Orblike 6 Abilities 30 Mods
Summary
Massive session building out the Orblike orb system: player slots, formations, beam carrier, modifier propagation, and compositional ability architecture. Added 6 new abilities (beam, lance, wall, snake, deploy, random_cast), ~30 modifiers, and several new systems (formation angles, spring-based orb movement, ability tags, cast triggers).
Orb Build Concept & Player Slots:
- Established the "orb build" archetype: 10-20 empty orbs as primary weapons via contact damage, contrasted with normal builds using 4-5 ability-loaded orbs
- Created player slot system (
p1:add_modifier,p1:add_ability,p1:get_mods()) for global modifiers that apply to all orbs - Key tension: player slots spent on orb behavior (contact damage, formations, orbit radius) can't be spent on ability enhancement
orb_contact_damagemodifier makes orbs deal damage on sensor collision with enemies- Player mods merge into every orb's mods table via
p1:get_mods()at the top oforb:activate()
Orb Movement — Spring System:
- Replaced rigid parametric orbit (
x = player.x + dist*cos(speed*time)) with damped spring on offsets - Spring operates on
ox, oy(offset from player), so player following is instant (zero lag) while orbit dynamics are springy - Parameters:
orb_follow_frequency = 20,orb_follow_damping = 0.8 - Orbs spawn at player position and spring outward with hit_circle + hit_particles effects
- Adding new orbs doesn't affect existing orb positions (random offset, no redistribution)
- Tested various approaches to make orbs follow player tightly while moving: adjusting damping, adding player velocity, lerp_dt center tracking — ultimately the offset-based spring solved it naturally
Formation System:
orb_formationglobal controls how orbs compute target positions viaorb:get_target_offset()build_formation_angles(r, mods)shared function builds directional arms from projectile modifiers (spreading, backshot, sideshots, nova, parallel)- All formations compose with these modifiers — e.g., lance + backshot = double-ended spear, wall + nova = 8 walls
- Formations are hold-type abilities on the player with speed_mult and turn_rate
- Turn rate limits player rotation while formation is active (
math.clampon angular diff per frame)
Formation Abilities:
- Lance: line from player in aim direction,
orb_spacing = 14between orbs. Speed 0.5x, turn rate 3. Usesp1.rfor direction (not mouse directly, so turn rate applies) - Wall: perpendicular line to aim. Speed 0.35x, turn rate 2. Orbs distributed using
n_in_rowcalculation with lateral offset - Snake: SNKRX-style — always moves forward, left/right to steer. Records position trail, orbs follow trail at distance-based intervals.
snake_turn_rate = 4 - Deploy: orbs deploy to mouse area using
math.poisson_disc_circle(). Slow-moving cursor (60px/s toward mouse). Speed 0.2x, turn rate 1. Supports magnetic_area (periodic pulse pulls enemies toward closest orb), growing_zone, shrinking_zone, area size modifiers
Ability Tags:
- Added
tagstable to all ability definitions ability_has_tag(name, tag)helper function- Renamed caustic_arrow to null_arrow with
nulltag - Tags: fire, null, area, duration, projectile, earth, melee, wind, chain, lightning, ice, force, channeling, formation, orb, beam
Null System:
- Abilities with
nulltag fire from orb position instead of player (lore: casters can't process null mana) null_conversionmodifier adds null behavior to any ability — fires from orb, color becomes purple- Startup visual: player→orb line (reversed from normal orb→player), purple particles
- All carrier code uses
fire_x, fire_yvariables set based on null status
Beam Carrier:
- Hold-type ability on orbs with animated dashed line visual (scrolling dashes with rounded caps)
- Ray simulation: step-by-step path building (3px steps) for homing support
- Homing: proximity-based (40px radius, not global nearest), each beam in a fan curves independently
- Path smoothing: stored
beam_pathslerped toward ideal path each frame (lerp_speed = 12*dt) to prevent abrupt changes - Beam width modifiers use parallel guide lines instead of thickening the center line (user: "the beam itself looking thicker makes it look wrong")
- Tick damage via point-to-segment distance check along path
- Tick speed affects drone pitch (
sound_handle_set_pitch) and dash scroll speed - White flash on dashes near source, transitions to beam color
- Startup: orb→player line + delay, then beam extends with lerp animation
- Sound:
beam_caston startup,beam_dronelooping via newsound_handle_set_loopingengine function
Beam Modifiers:
- Beam length: 6 tiers (slightly/increased/greatly increased/decreased), multiplier-based
- Beam width: flat increments (+1/+2/+3, -1/-2), visual guide lines at edges
- Tick speed: general modifier for beams AND zones, 6 tiers
- Homing turn rate: very_weak (0.0075), weaker (0.015), base (0.03), stronger (0.04) — applied to beams, projectiles, and zones
- Beam sweep:
beam_sweepmakes beam auto-rotate at 1.5 rad/s - All projectile formation modifiers (fan, parallel, backshot, sideshots, nova) create multiple beams via
build_formation_angles()
Ability Copy Modifier:
- On player: broadcasts player's manual ability to all orbs simultaneously
- On orb: when that orb fires, all other orbs fire the same ability with 0.08s stagger delay
- Orb-level copy uses
override_abilityparameter, guarded byif not override_abilityto prevent recursion
Channel Modifiers:
always_channel: hold abilities stay active without input (checked in both player update and orb beam update)trigger_while_channelling: auto-fires secondary abilities at 4x cooldown while primary channels- Player-level: triggers during formations (checks
any_formation) - Orb-level: triggers during beam channelling (checks
self.beam_active) - Two-pass processing in player update: hold abilities first (set
any_formation), then manual abilities
Cast Triggers:
cast_on_expire = N: fires secondary abilities at beam tip every N ticks- Uses
orb:secondary_abilities()to get non-primary abilities from orb slots - Fires through
orb:activate(sec_name, {x=tip_x, y=tip_y, r=tip_r})— full activate path with position override
Generic Activate Refactor:
orb:activate(override_ability, override_pos)— fire any ability from any position- All carriers (melee, self_area, aimed_area, chain, projectile, random) use
fire_x, fire_yinstead of hardcodedp1.x, p1.y override_posskips startup effects (line, flash, particles) and fires immediately- Player feedback (spring pull, flash) suppressed when firing from override position
- Self-area
followset to nil when override_pos (area stays at fire point, doesn't follow player)
Random Cast Ability:
carrier = 'random', picks frompooltable, callsself:activate(chosen, override_pos)- Forces all carriers to be modular — any ability must work when called generically
- Works as secondary with
trigger_while_channelling: beam + random_cast = periodic random spells from the orb
Engine Changes (anchor.c):
- Added
sound_handle_stop(handle)— stops and cleans up a playing sound immediately - Added
sound_handle_set_looping(handle, looping)— sets looping on a playing sound - Both use
sound_handle_decodefor stale handle detection - Lua bindings:
l_sound_handle_stop,l_sound_handle_set_looping, registered in init - Framework wrappers:
an:sound_handle_stop(handle),an:sound_handle_set_looping(handle, looping)
Shake System:
- Added
push_capto shake module — limits total directional push per frame (set to 12) push_usedtracked per frame, reset inearly_update- Prevents screen shake explosion when 20 orbs fire simultaneously
Utility:
math.poisson_disc_circle(radius, n)— generates N evenly-spaced points filling a circle via rejection sampling with adaptive min_dist relaxationsfx_handle(name, vol, pitch)— likesfx()but returns a handle for later control, logs to recording systemadd_orbs(n)— spawn N empty orbsorb:secondary_abilities()— returns non-primary abilities from slots
Sound Assets Added:
beam_cast: RPG3_ElectricMagic_Cast02 (volume 0.42)beam_drone: RPG3_PlasmaMagicEpic3_P5_BeamLayer_Loop (volume 0.37)- Both converted to OGG + lightmed bitcrushed variants

9→## Carriers — The fundamental object of the ability
10→
11→The carrier is what the ability creates in the game world — the entity or phenomenon that delivers effects to targets. Different carriers have different **modifier surface area**: the number of meaningful ways they can be changed by modifiers. Higher surface means more build diversity potential.
12→
13→**Design principle:** The most compositionally rich abilities deviate from "standard" carrier defaults on 1–2 axes while keeping other axes standard. The standard axes are where modifiers attach; the deviation is what gives the ability its identity.
14→
15→| Carrier | Description | Composability | Examples |
16→|---------|-------------|---------------|---------|
17→| Projectile | Discrete entity traveling through space | Very High — trajectory, count, and hit behavior all independently modifiable | Fireball, Ezreal Q, Sven Storm Hammer |
18→| Zone | Persistent region at a location, ticks over time | High — tick rate, duration, stacking, spatial mods | Caustic Arrow, Teemo mushroom, Gasoline |
19→| ~~Trap~~ | ~~Dormant zone that activates on a condition~~ | ~~High~~ | **→ Now a CTM (carrier-transforming modifier), not a standalone carrier. See Carrier-Transforming Modifiers section.** |
20→| Area | Instant region of effect at a point | High — inherent multi-hit, size/shape/cascade mods | Crystal Nova, Centaur Stomp, Reverse Polarity |
21→| Melee | Close-range hit or swing | Medium-High — attack speed × on-hit, splash is transformative | Nasus Q, Loader punch, Mercenary Laser Sword |

3→- **Cast on Return Apex** — Trigger point at the returning projectile's apex (where it reverses direction), allowing linked effects (explosion, nova, etc.) to fire at the turning point. Fits alongside other ORBS link trigger points like "Cast on Hit" and "Cast on Kill".
4→- ~~**DoT Sound**~~ — Done. Click sound 37 + Body Fall 18 merged.
5→- **Decreased Duration + Increased Damage** — Duration/damage tradeoff variants (concentrated effect style). Handle when doing damage system pass.
6→- **Shockwave Sounds** — Shockwave ability needs proper cast/hit sounds (currently using fireball_hit as placeholder).
7→
8→## Synergy Notes
9→
10→- **Worm Flask (enemy spawner item) + Infinite Chain** — An item that spawns additional enemies (like PoE's Writhing Jar worm flasks) would turn infinite chain into a powerful single-target damage source against bosses. The spawned enemies act as chain relay points, bouncing the chain back to the boss repeatedly.
11→
12→## Area/Zone Modifiers
13→
14→- ~~**Spell Cascade**~~ — Done. Renamed to Area Cascade.
15→- **Concentrated Effect** — Smaller radius, more damage. Classic tradeoff. Deferred to damage system pass.
16→- ~~**Increased Area of Effect**~~ — Done. Three tiers: slightly/normal/greatly.
17→- ~~**Decreased Duration**~~ — Done. Three tiers: slightly/normal/greatly.
18→- ~~**Increased Duration**~~ — Done. Three tiers: slightly/normal/greatly.
19→- ~~**Moving Zone**~~ — Done. Random diagonal drift.
20→- ~~**Homing Zone**~~ — Done. Drifts toward nearest enemy.
21→- ~~**Magnetic Area**~~ — Done. Areas: impulse pull + delayed detonation. Zones: per-tick impulse pull.
22→- ~~**Area Echo**~~ — Done. Repeats area/zone after delay.
23→- ~~**Growing Zone**~~ — Done. 2x size over duration.
24→- ~~**Shrinking Zone**~~ — Done. 0.5x size over duration.
25→- ~~**Zone Stacking**~~ — Done. Up to N zones stack damage per enemy.
26→- ~~**Zone Speed**~~ — Done. Three tiers: slightly/normal/greatly increased.

1→# Implemented
2→
3→## Abilities
4→
5→- **Fireball** — Projectile that explodes on hit, spawning an area that deals AoE damage.
6→- **Caustic Arrow** — Projectile that deals contact damage and spawns a persistent DoT zone on hit. Zone ticks damage periodically, with rotating arc segments that speed up on hit and decay to minimum speed. Blinks out on expiry.
7→- **Fissure** — Melee carrier. Spawns a sequence of rect areas in a line from the player with staggered delays. Camera shake on each wave.
8→- **Frost Nova** — Self-area carrier. Instant AoE centered on player that follows the player. Deals damage and applies guaranteed 50% slow for 2s. Supports cascade (diminishing radii), echo (re-aims at mouse), and magnetic area.
9→- **Windfield** — Aimed-area carrier. Rect AoE at mouse position with max range (150px). Deals damage, 50% chance to apply 50% slow for 2s. Per-ability cascade spacing and echo delay.
10→- **Arc** — Chain carrier. Auto-targets nearest enemy, chains between enemies with lightning_line visual. Each hop computed live (not pre-computed) with 0.08s delay between hops. Zigzag hit particles, blue hit circles, player-edge spawn effects. Supports all multi-source modifiers (spreading, backshot, sideshots, nova) as independent chain sources with angular cone targeting.
11→- **Shockwave** — Self-area carrier. Instant AoE centered on player, deals damage and knocks enemies away from center. White color. Placeholder sound (needs proper sounds).
12→
13→## Projectile Modifiers
14→
15→- **Homing** — Projectile steers toward closest enemy with quadratic distance falloff past 200 units. Convergence force and duration randomized per projectile at spawn.
16→- **Weaker Homing** — Lower convergence force and higher duration for softer tracking.
17→- **Stronger Homing** — Higher convergence force and lower duration for aggressive tracking.
18→- **Progressively Increasing Homing** — After 0.5s, convergence increases continuously at 15% of base value per 0.5s, capped at 0.95.
19→- **Progressively Decreasing Homing** — After 0.5s, convergence decreases continuously at 15% of base value per 0.5s, no lower limit.

Good, I've read through the full codebase and design docs. Here's my ideation on Blade Vortex and its modifiers:
Blade Vortex — Orbit Carrier
Core concept: Spinning blade entities orbit the player at a fixed radius. Enemies that contact a blade take damage. Duration-based — blades persist for a set time, then expire.
What makes it distinct from existing abilities: Every other ability in the game fires outward from the player. Blade Vortex is the first passive proximity offense — you deal damage by being near enemies, not by aiming at them. This inverts the gameplay loop: instead of kiting and shooting, you're weaving into enemy clusters.
Base Stats (first pass)
| Property | Value | Rationale |
|---|---|---|
| Carrier | orbit (new) |
Not a projectile, area, or chain — persistent rotating entities |
| Activation | manual |
Each cast adds blades (like PoE), or: single cast spawns all for duration |
| Blade count | 3 | Enough to be visible, sparse enough that rotation speed matters |
| Orbit radius | 24px | Just outside player hitbox (5px half-width), close enough to require proximity |
| Orbit speed | 2π/s (1 rotation/s) | Fast enough to feel active, slow enough that count matters for coverage |
| Hit cooldown | 0.5s per enemy per blade | Prevents machine-gun damage from standing still in an enemy |
| Duration | 6s | Long enough to feel like a "state," short enough to need recasting |
| Cooldown | 4s | Long — you're investing in a sustained effect |
| Color | fg_color (white) |
Neutral/sharp, like the blades are pure energy |
| Damage | 1 per hit | Same as everything else currently |
Key Design Decision: Activation Model
Two options worth discussing:
Option A: PoE-style stacking — Each activation adds 1 blade (up to a max, say 10). Each blade has its own duration timer. You spam-cast to build up, then maintain. The orb cooldown would be short (0.3s) but each blade expires independently.
Option B: Burst activation — One cast spawns all blades at once for the full duration. Simpler, more predictable. The modifiers that increase count just give more blades per cast.
I lean toward Option B for Orblike. PoE's stacking works because PoE has deep flask/charge/duration-extension mechanics. In Orblike, the interesting decisions happen in modifier composition, not in casting cadence. Burst activation keeps the "interesting stuff" in the build, not in the APM.
But Option A has a nice feel to it — the gradual spin-up, the maintenance gameplay. Worth prototyping both?
Visual
Blades could be small rounded rectangles (matching projectile style) oriented tangent to their orbit — they look like they're slicing through the air. On hit: hit_circle + hit_particles at the contact point, blade briefly flashes white.
The orbit itself should feel different from the ability-orbs already circling the player. Those orbs wobble randomly (orbit_distance is randomized, orbit_speed is randomized). Blade Vortex blades should be precise — uniform radius, uniform spacing, perfectly even rotation. The visual contrast signals "this is a weapon, not a UI element."
What Existing Modifiers Already Apply
These require zero new code in the modifier system — they'd work through the same mods table:
| Modifier | Maps to | Effect |
|---|---|---|
| Duration tiers | blade_vortex.duration |
1.5x / 2x / 3x / 0.75x / 0.5x / 0.25x duration |
| Area size tiers | orbit radius | 1.25x / 1.5x / 2x radius — bigger orbit = more coverage but less concentrated |
| Magnetic area | pull toward player center | Enemies get sucked into the blade ring — extremely strong synergy |
| Echo | re-cast blades after delay | Second wave of blades overlapping with the first |
| Growing zone | radius expands over duration | Blades spiral outward — covers more area as time goes on |
| Shrinking zone | radius contracts over duration | Blades spiral inward — concentrates damage, ends at melee range |
New Orbit-Specific Modifiers
These are unique to the orbit carrier and create its modifier identity:
1. Blade Count (+N blades) The most fundamental orbit modifier. More blades = more coverage = more DPS. Simple, satisfying, visually impressive. Three tiers feel right:
+2 blades(5 total)+4 blades(7 total)+7 blades(10 total, feels like a full ring)
2. Orbit Speed (faster/slower rotation) Directly impacts DPS — faster rotation = more hits per second. But also affects feel: slow rotation has a ponderous, heavy quality; fast rotation feels frantic.
slightly_increased_orbit_speed→ 1.3xincreased_orbit_speed→ 1.6xgreatly_increased_orbit_speed→ 2.5x
Decreased speed could pair with increased damage (concentrated strikes).
3. Chariot (front cluster)
Blades rearrange from a ring to a forward-facing cluster, biased toward the player's aim direction. Instead of uniform spacing around 2π, blades cluster within ±60° of p1.r. Turns Blade Vortex from passive defense into aggressive melee offense — you have to face enemies to hit them, but the concentrated blade density is devastating.
This is conceptually rich: it transforms the playstyle from "walk into enemies" to "aim at enemies while close."
4. Lance (forward line) Blades arrange in a line extending from the player in the aim direction. First blade at orbit radius, subsequent blades at increasing distances. Turns the ring into a blade-tipped spear. The "orbit" becomes more like a forward sweep — blades oscillate side-to-side in front of you.
Probably simpler to implement than Chariot but less interesting in practice?
5. Ringshot (fire all outward) All blades simultaneously launch outward as projectiles from their current positions. This could be:
- An automatic trigger (on duration expire, blades fire outward as a final burst)
- A manual recast (press again to detonate)
- Triggered by a modifier
The appeal: you build up a ring of blades, position yourself in an enemy cluster, then release them all at once. Each blade becomes a projectile that inherits any projectile modifiers on the orb. This is the orbit-to-projectile bridge — composability gold.
6. Tethered (damage web) Lightning/energy arcs between adjacent blades. Enemies that cross a tether take damage. With 3 blades, you get a damage triangle. With 10 blades, you get a damage decagon. The tethers create a "fence" effect — anything inside the orbit radius takes persistent damage, not just things that contact a blade.
This synergizes obscenely with blade count (more blades = more tethers = more coverage) and with magnetic area (pull enemies into the damage web).
7. Fire and Return Individual blades can briefly leave orbit to strike a nearby enemy, then return to their orbit slot. Auto-targeted (nearest enemy within range). Each blade fires independently on its own cooldown. Gives the orbit carrier some ranged capability without changing the fundamental playstyle.
Modifier Combos That Get Exciting
- Blade Vortex + Magnetic Area + Tethered — enemies get sucked toward the player, into a web of damage arcs between orbiting blades. The ultimate "death ball."
- Blade Vortex + Ringshot + Nova — build up 10 blades, walk into a pack, fire all outward. But wait — nova is already "fire in all directions." Maybe Ringshot IS the orbit's nova equivalent?
- Blade Vortex + Chariot + Increased Orbit Speed — forward-facing buzzsaw. Aggressive melee playstyle.
- Blade Vortex + Growing Zone + Blade Count — starts as a tight ring, expands to cover half the screen. A slowly expanding ring of death.
- Blade Vortex + Echo + Duration — double-layered blade rings with extended duration. Sustained area denial.
- Blade Vortex + Fire and Return + Homing — blades actively seek enemies and return. Turns passive offense into semi-active targeting.
Open Questions
Does the orbit carrier need its own object class, or can it reuse/extend
area? Areas already have follow, radius, duration, tick-based damage. An orbit could be an area with N blade sub-entities that rotate. But the per-blade hit tracking and orbit-specific mods might warrant a dedicated class.Hit tracking: Per-blade per-enemy cooldown, or per-rotation? Per-blade is more granular (and rewards blade count more). Per-rotation is simpler and makes blade count purely about coverage gaps.
Do blades visually overlap the ability-orbs? The player already has white orbs circling. Blade Vortex blades would also circle. They need to be visually distinct — different shape (elongated vs. circular), different orbit behavior (uniform vs. randomized), different layer (game layer for blades vs. wherever orbs draw).
Should Blade Vortex compose with the multi-source modifiers? (spreading, backshot, sideshots, nova) These are projectile-centric. For orbit, the equivalent is Chariot/Lance/Ringshot. Might be cleaner to keep orbit modifiers separate from projectile modifiers.
What aspects of this are you most interested in? I can go deeper on any of these, or we can start narrowing toward implementation.
Doesn't this feel redundant with the orbs themselves? Some of the interesting modifiers you have (lance, chariot, ringshot, etc) all sound like things you'd do to control the orbs as they deal damage. Maybe this should all just be the orb build instead?
You're completely right, and I think this is a much better direction.
The game already has entities orbiting the player. Blade Vortex as a separate ability would just create more things orbiting alongside them — visually cluttered and conceptually redundant. The interesting insight is that the orbit modifiers (chariot, lance, ringshot, tethered) are really about how the orbs themselves move and deal damage.
So the design becomes: Blade Vortex is the ability that says "this orb IS the weapon." You slot it into an orb, and instead of the orb firing something outward, the orb itself deals contact damage as it orbits. Then the orbit modifiers change the orb's orbit behavior — which is already partially defined by orbit_distance, orbit_speed, orbit_offset.
This has some nice consequences:
- Mixed builds. 2 blade vortex orbs (close-range contact damage, maybe tethered for arcs between them) + 2 fireball orbs (ranged). Your orb loadout becomes a melee/ranged ratio decision.
- Orbit modifiers are orb modifiers. Chariot doesn't create new entities — it rearranges where the blade vortex orbs cluster. Lance extends them forward. Ringshot fires the orbs themselves outward as projectiles.
- The orb's position matters tactically. Currently orbs are decorative — they orbit but their position doesn't affect gameplay. With blade vortex, where your orb is at any moment determines what gets hit.
One tension: currently all orbs share the same orbit ring (evenly spaced via orbit_offset). If only some orbs are blade vortex, do the blade vortex orbs get their own controlled orbit while the others wobble freely? Or does the orbit pattern affect all orbs on the ring?
And a bigger question: if blade vortex makes the orb the weapon, does it still make sense for that orb to also hold another ability? Or is "blade vortex" mutually exclusive with projectile/area/chain abilities — you're choosing between "this orb fires things" and "this orb hits things directly"?
Forget Blade Vortex for a second. You mentioned a lot of positions (chariot, etc) which are basically formations on the orbs. Orb builds can have things like more orbs, higher orb speed, orb contact damage (this is what makes the build work primarily), and then the various formations and other modifiers that we think might apply. Then we may have abilities that are player-centered, not orb-centered. We had the idea of "global modifiers", these would be like player-based modifiers, where the player is something like an additional board where abilities and modifiers can go, except they affect everything. Here instead you have your orb build modifiers, which adds some tension between choosing global modifiers that help all your orb abilities vs. focusing on orb builds and doing other things. So an orb build is like, have "global orb modifiers" on player slots, then on the orbs you may or may not have abilities, but those abilities won't be strong because your modifiers will be focused on changing and adding to orb behavior. You may also have waaaaaaaaay more orbs than a normal player. While a nomral build may have 4-5 orbs, an orb build might have 10-20, most of which will have nothing in them because they're just there to deal damage. Makes sense?
Yeah, this makes a lot of sense. It's a genuine build archetype with its own identity and tradeoffs.
The core tension is player slot allocation. Player slots are a shared resource — every slot you spend on "chariot formation" or "+5 orbs" is a slot NOT spent on "all projectiles gain homing" or "increased area of effect." So an orb build is a commitment: you're investing your global modifier budget into making the orbs themselves deadly, at the cost of having weaker abilities.
And then the orb count scaling reinforces this. A normal player has 4-5 orbs, each loaded with an ability and modifiers — the orbs are delivery vehicles. An orb build player has 10-20 orbs, most empty — the orbs ARE the damage. The few abilities you do slot in are utility or supplementary (maybe a frost nova for slow, an arc for finishing stragglers), not your main damage source.
What I find interesting about this:
Empty orbs become a "resource." In a normal build, an empty orb is waste. In an orb build, each empty orb is another body in your formation dealing contact damage. The "+N orbs" modifier is boring for normal builds but is the core scaling stat for orb builds. That's good design — same modifier, different value depending on context.
Formations change the playstyle. Default ring is passive — you just walk near enemies. Chariot means you have to aim (face enemies). Lance means you're jousting. These aren't just stat changes, they change how you physically play the game. That's the kind of modifier depth that's hard to get from projectile modifiers (which mostly just change numbers).
The visual identity is distinct. 20 orbs in chariot formation swarming through enemies looks and feels completely different from 4 orbs launching fireballs. You can immediately tell what kind of build someone is running.
Some things I'm uncertain about:
How does contact damage scale? If each orb does 1 damage on contact with a per-enemy cooldown, then 20 orbs is 20x the damage of 1 orb — but only if enemies stay in the formation long enough to get hit by all 20. Formations that concentrate orbs (chariot) would be higher single-target DPS but lower coverage than ring. Is that the right knob, or does the global modifier also boost per-orb damage?
Do formations affect ALL orbs or only empty ones? If you have 15 empty orbs in chariot formation + 2 ability orbs, do the ability orbs also cluster forward? Or do they maintain their own orbits? Having them join the formation could be interesting — your fireball orb is now in front of you, so it fires from a different position.
Ringshot specifically — if this is a global modifier that fires all orbs outward as projectiles, what happens to orbs with abilities? Do they fire their ability? Do they just do contact damage as they fly out? This could be the bridge between orb builds and ability builds — ringshot turns your 20-orb formation into a 20-projectile nova burst.
Let's answer these questions by creating the various builds and the system. Let's have only no-ability no-modifier orbs on the player for now. Maybe add a helper to add multiple of them at once.
Here's the code for adding multiple empty orbs. Currently the setup at line 2322 creates 6 orbs with abilities — I'd replace that with a single helper call:
function add_orbs(n)
for i = 1, n do
add_orb()
end
end
And then the spawn section becomes:
-- Spawn player
p1 = player(gw/2, gh/2)
an:add(p1)

Done. 10 empty orbs, no abilities, no modifiers. The orb-enemy sensor collision handler is already registered (line ~2397) — it's just empty, ready for contact damage when we get to that.
OK, what's the current speed range and radius of orbs spawned?
From orb:new (line 142-143):
self.orbit_distance = an.random:float(16, 64)
self.orbit_speed = an.random:float(2, 4)
So radius is 16–64px, speed is 2–4 rad/s (roughly 0.3–0.6 rotations per second).
Let's make sure there are bands of orb spawning lanes. So 16, 24, 32, etc. Actually, the distance between each band should increase the closer it is to the final radius (64) so it isn't linear. Speed is fine as is for now. Let's start with 5 lanes to see what it looks like.

5 lanes at: 16, 22, 33, 47, 64 px. Orbs assign round-robin — orb 1 → lane 1, orb 6 → lane 1 again, etc.
Perfect, now let's work on radius increase/decrease modifiers. These should change the radius such that, primarily, we're working with less/more bands. So slightly increased orbit radius should increase the radius such that we have maybe 2 more bands, while greatly increased one should double the number of bands, right? Similar logic for decreased ones.
So the modifier changes the lane count (and extends/shrinks the max radius accordingly). More bands = orbs extend further out. Fewer bands = tighter around the player.
Tiers:
- Slightly increased → +2 lanes (7), max ~88px
- Increased → +3 lanes (8), max ~100px
- Greatly increased → +5 lanes (10), max ~124px
- Slightly decreased → -1 lane (4), max ~52px
- Decreased → -2 lanes (3), max ~40px
- Greatly decreased → -3 lanes (2), max ~28px

Now generate_orb_lanes(N) + reassign_orb_lanes() is all a modifier needs to call. For testing you can just do generate_orb_lanes(10); reassign_orb_lanes() in a debug key. The actual modifier system (player slots, global modifiers) can plug into this later.
Let's actually add the player slots + these actual modifiers in it. You should also make it so that whatever is added to the player slots, applies to ALL orbs. So if we have an area increase modifier in a player slot, it's as if it was in all orbs simultaneously, makes sense?

Done. Here's what's in place:
Player slots:
p1:add_modifier(name, value)— adds a global modifier, auto-applies orbit effectsp1:remove_modifier(name)— removes itp1:get_mods()— returns all player mods as a table
Global propagation: In orb:activate(), the mods table now starts with p1:get_mods() and then overlays orb-specific mods on top. So any modifier on the player applies to every orb's ability as if it were on that orb directly.
Orbit radius modifiers: Adding/removing them triggers apply_global_modifiers() which regenerates lanes and reassigns all orbs.
Currently spawning with slightly_increased_orbit_radius for testing (7 lanes instead of 5). You can swap that out or remove it.
Why do you have an apply_global_modifier function that specifically names the modifiers we're adding? The system should be such that ANY modifier can be added to the player and will be global. These modifiers we're adding should be no different from the ones we added before.
You're right. add_modifier/remove_modifier should just store data — no special callbacks. The orbit radius modifiers get checked where the orbit distance is computed, same pattern as area size modifiers being checked in area:new().

Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
orb_contact_damage is a player modifier with a numeric value. The collision handler checks it — if it's > 0, orbs deal that much damage on contact with hit feedback (hit_effect, spring pull, flash, particles). Stackable by design — p1:add_modifier('orb_contact_damage', 2) would deal 2 per hit.
There's a big hit circle happening on top of the all the effects. Like, too many effects happening at once.
The hit_effect (spritesheet animation) is too much for frequent contact hits. Let me strip it down — orb contact should be light feedback since it happens constantly.
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Stripped it to just: damage (with quieter hit sound via 0.3 volume), orb spring pull + flash. No hit_effect, no extra particles — take_damage already handles the enemy-side feedback.
Add the hit particles, add back normal hit effect and damage volume. Let me check something

0.8 volume. Now let's change the orb adding behavior such that it doesn't affect how all other orbs are moving? Currently it kinds of does. Actually, let's remove the lane system and just have orbs spawn randomly within the range (always starting at 16).

Perfect, now we need a less rigid system of movement for the orbs. Currently, they follow a pretty strict path. But if we want this to feel fluid, they need to behave more like birds/boids in a steering behavior system than following a super fixed path. Their movement should be fluid so that we can animate the transition between formations in a nice way. The default behavior should be exaclty the same as it is now in terms of movement, they should orbit within a given radius like they do now, but it shouldn't be coded in a fixed way. Does that make sense? For instance, when spawning an orb we should be able to have it spawn near the player, and then it should move towards its position in the orbit and starting orbitting naturally, instead of just spawning directly while in orbit. First, tell me how you plan to accomplish all this.
Here's my plan:
Current system: Position is computed directly from a formula each frame — x = player.x + dist*cos(speed*time + offset). No velocity, no dynamics. The orb teleports to its computed position every frame.
Proposed system: The formula still exists, but it computes a target point, not the actual position. The orb has velocity (vx, vy) and steers toward the target with a spring-like force + damping:
-- Target orbits the player (same formula as now)
local tx = p1.x + self.orbit_distance*cos(self.orbit_speed*time + self.orbit_offset)
local ty = p1.y + self.orbit_distance*sin(self.orbit_speed*time + self.orbit_offset)
-- Orb steers toward target
local dx, dy = tx - self.x, ty - self.y
self.vx = self.vx + dx*stiffness*dt
self.vy = self.vy + dy*stiffness*dt
-- Damping prevents overshoot
self.vx = self.vx*damping
self.vy = self.vy*damping
-- Position updates from velocity
self.x = self.x + self.vx*dt
self.y = self.y + self.vy*dt
Why this works for everything you want:
- Default orbit: With tight stiffness + damping, the orb hugs its target closely — visually identical to current behavior, but with slight natural lag
- Spawn: Orb starts at the player's position. Target is already orbiting. Orb smoothly drifts outward and falls into orbit
- Formation changes: Change how the target is computed (chariot clusters targets forward, lance lines them up). The orb smoothly transitions because it's just steering toward a new target position — no teleporting
- Knockback/disruption: You could push orbs off their path and they'd recover naturally
The orbit formula becomes a "where should I be" signal, and the steering system is "how do I get there." Same pattern as the enemy seeker's steering, just applied to orbs.
Does this approach make sense, or would you change anything about it?
Can you use something like the math functions that have p, t parameters for stiffness, damping so I have more intuitive control over it?
Yeah — just use math.lerp_dt(p, t, dt, current, target) directly on position. Same pattern as the player's aim smoothing (math.lerp_angle_dt(0.99, 0.1, dt, ...)). No velocity tracking needed:
self.x = math.lerp_dt(p, t, dt, self.x, tx)
self.y = math.lerp_dt(p, t, dt, self.y, ty)
p = how tightly it follows (0.99 = snappy, 0.5 = floaty), t = time constant. Store them as self.orbit_p and self.orbit_t on the orb so you can tune them. Want me to go ahead and implement this?
Wait, you mentioned spring-like movement before, doesn't this remove it?
You're right — lerp_dt is purely convergent, no overshoot. A spring has momentum so it can overshoot and settle, which is what gives it that lively organic feel.
For spring dynamics with intuitive control, the standard damped spring uses two parameters:
- frequency — how snappy/responsive (higher = faster response)
- damping — how bouncy (1.0 = no overshoot, 0.7 = slight overshoot, 0.5 = bouncy)
local dx, dy = tx - self.x, ty - self.y
local w = self.orbit_frequency
local z = self.orbit_damping
self.vx = self.vx + (w*w*dx - 2*z*w*self.vx)*dt
self.vy = self.vy + (w*w*dy - 2*z*w*self.vy)*dt
self.x = self.x + self.vx*dt
self.y = self.y + self.vy*dt
So you'd tune with something like orbit_frequency = 8, orbit_damping = 0.8 — snappy with slight overshoot. These are more intuitive than raw stiffness/damping and give the spring character that lerp_dt doesn't. Want me to go with this?
Let's try it.

Orbs now spawn at the player's position and spring outward into orbit. orbit_frequency = 8 (snappy), orbit_damping = 0.8 (slight overshoot). You can tweak those values to feel it out.
Orbs are currently spawning at 0, 0, not the player's position.
The issue is p1 doesn't exist yet when the orbs are created — the player is spawned first but p1 is only assigned at the spawn section. Let me check the order:

Wait — the collider is created after self.x, self.y but never positioned. The collider defaults to (0,0). I need to set its position:

Doubles the spring frequency while the player is moving — orbs snap to their orbit positions more tightly so they keep up. When standing still they return to the looser, floatier follow.
This also makes the orbits spin faster, they should only follow stronger but not spin faster.
Right — increasing frequency makes the whole spring tighter, which includes the orbital motion. Instead, I should add the player's velocity directly to the orbs when moving — that way they're dragged along with the player without changing the orbit dynamics.
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Now the orbit spring stays the same speed, but the player's velocity is fed into the orbs as an extra force when moving. The *4 multiplier controls how strongly they're dragged along — you can tune it.
It's still slow. We want the equivalent of p, t arguments where we can change one of them so that the duration of the lerp is lower or higher.
[Request interrupted by user]
While still keeping the springy movement, of course.
The problem is the spring frequency controls both orbit-tightness and player-following-tightness simultaneously. I should separate them: a follow_p, follow_t (lerp_dt) for tracking the player's position, and the spring for the orbit dynamics around that tracked position.

Halves the damping while moving — orbs will overshoot more and feel bouncier/looser when following the player around. Same orbit speed though.
Let's try to increase it.

Doubles damping while moving — orbs will be more critically damped and track tighter with less overshoot.

Uh, let's go back to no difference when player moving. Nothing we tried made the orbs actually follow the player's relative position more tightly, there's always a delay.
Edit (E:\a327ex\Orblike\main.lua)

The reason nothing worked is that the spring operates on absolute position — so the orb is always chasing the player. The fix is to run the spring on the offset from the player instead. That way the orb always moves with the player perfectly (zero lag), but the orbit around the player has spring dynamics:
-- Spring on offset, not absolute position
local target_ox = self.orbit_distance*cos(...)
local target_oy = self.orbit_distance*sin(...)
-- spring self.ox, self.oy toward target_ox, target_oy
self.x = p1.x + self.ox
self.y = p1.y + self.oy
The player-following becomes instant (it's just addition), and the springiness only affects how the orb settles into its orbit. Want me to switch to this?
Let's try.

Now the spring runs on the offset (ox, oy) — the orb starts at offset (0,0) (player's position) and springs outward into orbit. Player following is instant via p1.x + self.ox. The H push key should still work since it adds to velocity — let me update it to use ovx, ovy:
Grep (o.vx = o.vx)
2462- local push_r = p1.r

2464: o.vx = o.vx + 300*math.cos(push_r)

Now orbs follow the player with zero lag, and the spring only affects the orbit around the player. Spawning starts at offset (0,0) and springs outward.
Yes, perfect. Now let's add an ability that arranges all orbs into a line from player to mouse. The orbs should always be equally distant.

1 orb 16 awy from player, 1 orb at mouse, then the middle fills with equally distant ones.

F toggles between orbit and lance formation. In lance mode, first orb sits 16px from player, last orb at mouse position, rest fill in with equal spacing. The spring handles the transition smoothly.
Instead of equally distant, let's keep the distance equal and then the sword just points in the direction of the mouse and has a length of however many orbs you happen to have. Can we also make the orbs follow the target position faster? Or let's make this a variable that can also be changed by orb modifiers, formation follow speed I guess?

Doubled the frequency to 16.
Perfect. Let's add 5 modifiers, instead of slightly/greatly, let's follow the delayed/very delayed homing naming convention. What should they be called, for faster/slower orb formation following?
Following the homing naming style (describing the character rather than just more/less):
Frequency (how fast orbs reach target):
snappy_formation— higher frequency, orbs snap to position fastervery_snappy_formation— even fastersluggish_formation— lower frequency, orbs drift lazilyvery_sluggish_formation— even slower
Damping (how much overshoot):
bouncy_formation— lower damping, orbs overshoot and oscillate more
That's 5, covering both axes. "Snappy/sluggish" reads immediately — you know what it does without thinking. And "bouncy" is a separate feel dimension from speed, like how "delayed homing" is a different axis from "weaker homing."
Does this naming work for you?
Need somewhat more formal and autistic names than snappy and sluggish
Faster:
responsive_formationhighly_responsive_formation
Slower:
dampened_formationheavily_dampened_formation
Overshoot:
elastic_formation
I like responsive, dampened feels wrong
How about:
delayed_formation/very_delayed_formation
Mirrors the homing convention directly. Or if you want something that conveys the physical quality:
inertial_formation/very_inertial_formation
delayed. responsive = 2x, very_responsive = 3x, similar for the downside. Let's try it and test it, give me a key to change between them. Also do elastic_formation in whatever way you think is correct and give me a second key to toggle it.

Now the keys cycle through actual player modifiers: G cycles normal → delayed → very_delayed → responsive → very_responsive, B toggles elastic_formation. The orb update reads these from p1:get_mods().
Once it becomes very responsive, when it becomes very delayed again it's not actually delayed?
The orbs still have all their velocity from the high-frequency spring. When you switch to low frequency, the weak spring can't rein them in. I need to reset velocities on switch:

Zeroes all orb velocities when switching response mode so they don't carry momentum from the previous setting.
Still not working.
The bug is ipairs stops at the first nil in the table — so modes[1] = nil means the removal loop never runs. None of the old modifiers get removed.

Done. Debug keys removed, very_responsive_formation added as a player modifier.
Perfect. What other formations are there?
From our earlier ideation and the design reference:
Already implemented:
- Orbit — default circular orbiting, random radii/speeds
- Lance — line from player toward mouse, fixed spacing
Remaining interesting ones:
Chariot — orbs cluster in a wedge/group in front of the player toward mouse. Aggressive melee formation — concentrated damage in the aim direction, but your back is exposed.
Shield — orbs form a line perpendicular to the mouse direction. A defensive wall between you and what you're facing. Opposite philosophy to lance.
Ring — evenly spaced at a fixed radius, no random wobble. A clean damage circle. Distinct from default orbit because it's uniform and predictable.
Tethered — not a formation per se, but a modifier that adds damage arcs between adjacent orbs. Works with any formation but gets interesting with ring (damage polygon) or shield (damage fence).
Ringshot — also not a formation but an action: all orbs fire outward from their current positions as projectiles. A "detonate the formation" burst.
Which of these interest you? Chariot and shield feel like the most distinct gameplay from lance and orbit — they change how you position relative to enemies.
Let's make it so that each mode is actually an ability, and each ability behaves like an ability does regarding input. The lance ability forms the lance it does now while the player holds down the button, but the player's movement speed is decreased by 50%.

OK, list the other formations again please
From the design reference:
- Chariot — orbs cluster in a wedge/group in front of player toward mouse. Concentrated forward damage, exposed back.
- Shield — orbs form a line perpendicular to mouse direction. Defensive wall.
- Ring — evenly spaced at a fixed radius, uniform rotation. Clean damage circle, no random wobble.
And modifier-like additions that layer on top of any formation:
- Tethered — damage arcs between adjacent orbs. Ring becomes a damage polygon, shield becomes a damage fence.
- Ringshot — all orbs fire outward from current positions as projectiles. "Detonate the formation" burst.
Let's make it so that the projectile modifiers in terms of projectile formation also apply here.
The projectile formation modifiers (backshot, sideshots, nova, spreading) already live as player mods. I just need to read them in get_target_offset and distribute orbs across the resulting angles.

build_formation_angles is shared — same angle logic as the projectile system. Orbs distribute round-robin across arms: with 10 orbs + backshot, 5 orbs lance forward, 5 lance backward. Same function will work for any future formation that uses directional arms.
Right-click to see it. Backshot is there for testing — you can swap it for sideshots, nova, or spreading_multiple_projectiles.

Parallel creates side-by-side lanes along each arm, spaced by orb_spacing. With parallel 3, you get 3 parallel lances.
Does it handle combinations, like fan 2 parallel 2?
Yes, it should — the distribution uses total_arms = #angles * parallel, so fan 2 + parallel 2 = 4 total arms (2 fan directions × 2 parallel lanes each). Let me set it up to test:
Edit (E:\a327ex\Orblike\main.lua)

When a formation ability is held, the player turns at a fixed turn_rate (radians/second) instead of snapping to the mouse. Lance has turn_rate = 3 (~172°/s) — you can sweep the formation around but not instantly whip it. Tune the value to taste.
Let me see 1 turn rate
Edit (E:\a327ex\Orblike\main.lua)

Doesn't seem like it's actually respective the turn rate at all. Setting r directly doesn't seem to be doing anything to affect how fast the orbs follow. I believe the player is turning slowly, but the orbs keep following the mouse normally
The lance formation computes its angle directly from the mouse (math.atan(mouse - player)), ignoring p1.r. It should use p1.r instead:

Perfect. Let's try another formation.
From our list:
- Chariot — orbs cluster in a wedge forward, concentrated damage ahead
- Shield — orbs form a wall perpendicular to aim direction
- Ring — evenly spaced at fixed radius, uniform rotation (no random wobble)
Which one do you want to try?
We need to think of formations that actually have different gameplay behavior. The lance allows for long range targetting. What do the others do that's different from long range and orbit? We need to think of more shapes that cover different cases.
The key question is: what different player behavior does each formation create?
- Lance → you AIM at things. Directional, ranged. Rewards facing enemies and holding position.
- Orbit (default) → you WALK INTO things. Omnidirectional, close range. Rewards positioning in enemy clusters.
So what other engagement patterns exist?
Wall — perpendicular line. You FACE things. It's a wide-but-short barrier. Gameplay: advance into groups and the wall sweeps through them as you turn. Like lance but width instead of depth. Good against wide packs, bad against single targets at range. Opposite tradeoff from lance.
Whip — orbs trail behind your movement path with delay. You CIRCLE things. Faster you move, wider the sweep arc. Rewards aggressive circular movement around enemy clusters. The tail whips through everything in your path. Stationary = useless (orbs just collapse on you). This is the most movement-dependent formation.
Concentrate — all orbs collapse to a single point at fixed distance ahead. You RAM into things. Maximum single-target DPS, zero coverage. Like a battering ram. Simplest mechanically, most extreme tradeoff.
Scatter — orbs deploy to fixed world positions and stay. You PLACE AND LEAVE. Creates a danger zone you can kite enemies through. You lose your orbiting damage but gain area control. When released, orbs spring back.
Each one rewards fundamentally different movement:
- Lance: hold still, aim
- Wall: advance, sweep
- Whip: circle, keep moving
- Concentrate: charge straight at one target
- Scatter: kite enemies through your field
Which of these interest you?
All of them interest me, very good coverage of ideas. Let's do wall. Are you thinking of it as similar to lance with sideshots or something different?
Different from lance + sideshots. Lance + sideshots gives three lances (forward, left, right) — each one is multiple orbs deep.
Wall is the perpendicular concept: all orbs in a single row across the aim direction. No depth, all width. Like a shield line:
o o o o o o o o o o
[player] →
Orbs are evenly spaced along the perpendicular axis, centered on the player (or with a small forward offset). The gameplay is about sweeping — you turn and the wall scythes through everything in an arc.
It composes with the existing modifiers differently than lance:
- backshot → wall behind you too (front and rear guard)
- parallel → multiple parallel walls at different forward distances (depth layers)
- spreading → V-shaped wall (angled wings)
So it's a genuinely different formation, not a lance modifier combo. Want me to implement it?
Yes.

Right-click for lance, space for wall. Wall has higher speed (0.7x vs 0.5x) and faster turn rate (4 vs 3) since it's more about sweeping than aiming. 20 orbs in a line perpendicular to where you're facing.
Add to to_implement: null abilities always fire from the orb instead of the player. Lore-wise reason for this is that casters can't process null mana, only the orbs can, so null abilities should come from the orbs. Whereas other spells process null mana, sends the processed mana to the caster, and then the caster casts the spell using his body.

Given wall and the 3 ideas I just mentioned, can you think of what combo I'm thinking?
A wall of beams.
Channelling beam ability (permanent, always on) + null (fires from each orb's position) + linked (every orb gets it) + wall formation = 20 parallel beams firing forward from a perpendicular line. A laser curtain you sweep through enemies by turning.
The turn rate on wall makes it so you can't just instantly whip 20 beams across the screen — you have to deliberately sweep, which is the gameplay.
Yes, that would work too. But I was actually thinking of linking the permanent channelling to wall itself, so you don't have to hold it to have it active, and then just like something like fireball to all orbs. But both ideas work, right?
Yeah, both work. Your version is arguably cooler because it uses existing pieces — make wall itself a permanent channelling ability (always on, no hold), then link fireball to all orbs. You get a permanent firing line of 20 orbs in wall formation, each launching fireballs. A walking artillery battery.
The three rules compose in different ways to produce different results:
- Your combo: permanent wall + linked fireball = artillery line
- My combo: wall + permanent null beam = laser curtain
Same building blocks, different assemblies. That's exactly the ORBS composability working as intended.
OK, implement wall.
Wall is already implemented and bound to space. It's in the abilities table, the formation code in get_target_offset, and assigned via p1:add_ability('wall', {key = 'space'}).
Hold space to activate — 20 orbs form a perpendicular line, 0.7x speed, turn rate 4. Right-click still does lance.
Or did you mean implement one of the other formations (whip, concentrate, scatter)?
Make L spawn enemies at mouse position and triple the number of enemies spawned.

Let's make null abilities always fire from orbs. To do this, we should also add tags to abilities in-game, so we have a clear way of telling which abilities have the null tag. Let's tag all abilities we have in the game so far. Show me your proposed list of tags, and I'll correct any mistakes.
Here's my proposed tag list. These are mana type tags — the type determines whether the ability fires from the caster (processed mana) or from the orb (null/raw mana):
| Ability | Tags | Reasoning |
|---|---|---|
| Fireball | fire, projectile |
Elemental fire projectile |
| Caustic Arrow | poison, projectile |
Toxic/caustic element |
| Fissure | earth, melee |
Ground/earth manipulation |
| Windfield | wind, area |
Air element |
| Arc | lightning, chain |
Electric element |
| Frost Nova | ice, area |
Cold element |
| Shockwave | force, area |
Pure physical force, no element |
| Lance | null, formation |
Direct orb manipulation, no mana processing |
| Wall | null, formation |
Direct orb manipulation, no mana processing |
The split I'm uncertain about: Shockwave — is it force (processed through the caster) or null (raw orb energy)? It's a pure force push with no element, which could go either way. As null it would fire from each orb's position instead of the player, which would actually be interesting gameplay.
Fireball - area, fire, projectile Null Arrow - area, duration, null, projectile Fissure - area, earth, melee Windfield - area, wind Arc - chain, lightning Frost Nova - area, ice Shockwave - area, force Lance - channeling, formation, orb Wall - channeling, formation, orb

The sound names can stay as caustic_arrow_fire/caustic_arrow_zone — they're just asset references. I only need to update the ability name references in the game logic:

Done. Renamed caustic_arrow → null_arrow, added tags to all abilities, and added ability_has_tag(name, tag) helper. The null tag is on null_arrow — ready for the "null fires from orbs" behavior when you want to implement it.
Perfect, now let's implement the null from orb behavior, let's test it with null arrow too.

Now I see the structure. For null abilities:
- Skip the orb-to-player line (no mana transfer needed)
- Fire from the orb's position instead of the player's position
- Use the orb's angle to the mouse for aiming instead of
p1.r

I see — the shots use p1.x, p1.y as the origin. For null abilities, these should use self.x, self.y (the orb's position). The aim direction r should also be from the orb to the mouse instead of using p1.r.
The cleanest approach: at the top of the activate function, determine the fire origin and aim angle based on whether the ability is null:

Should the linked ability override orbs that already have their own ability, or only fill in empty orbs? I'm guessing empty orbs only — since in an orb build most orbs are empty, and orbs with their own abilities should keep them.

The file E:\a327ex\Orblike\main.lua has been updated successfully.
All 20 empty orbs now fire fireball (from the player, since fireball isn't null). Mouse 1 to fire — whichever orb's keybind matches will activate it. The linked ability only fills in orbs that don't have their own.
Add null conversion to player too. Due to how these modifiers work, they should already automatically apply to the other orbs as well.

The file E:\a327ex\Orblike\main.lua has been updated successfully.
Since null_conversion is checked via p1:get_mods() which all orbs already read, every orb's linked fireball should now fire from the orb's position in purple.
OK, but we need to actually have fireball on the player, and thus when fireball fires, if it's linked with the copy modifier, then that will carry over to the orbs. We currently don't have fireball on the player nor an input method there.
Right — the ability lives on the player with a keybind, and a modifier makes it cascade to all orbs. Let me rework this.
First, add manual ability handling to the player update, and a linked modifier that broadcasts to orbs:

1407: if mods.linked_ability then
2577:p1:add_modifier('linked_ability', 'fireball')
2578:p1:add_modifier('null_conversion')

Now fireball is on the player (mouse 1), linked_ability broadcasts it to all orbs on fire, null_conversion makes them fire from the orbs in purple. The orbs' own keybinds don't matter here — the player's ability triggers all orbs directly.
Let's call it ability_copy instead
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated. All occurrences of 'linked_ability' were successfully replaced with 'ability_copy'.
Because all abilities are firing at once, the directional shake is very strong, let's add a cap to it.
Grep (shake:push)
463: an.camera.shake:push(r, 4)
722: an.camera.shake:push(r, 3)
2727: an.camera.shake:push(r, 2)
2749: an.camera.shake:push(r, 2)
2771: an.camera.shake:push(r, 2)
2792: an.camera.shake:push(r, 3)
Grep (shake:shake)
358: self.timer:after(wave_delay, function() an.camera.shake:shake(6, 0.4) end)
365: an.camera.shake:shake(8, 0.4)
421: an.camera.shake:shake(6, 0.3)
532: an.camera.shake:shake(3/hop, 0.15)
The simplest approach is to wrap the shake:push call so it caps the total accumulated push per frame:
Read (E:\a327ex\Orblike\main.lua)

What will you do exactly?
I'll track accumulated shake per frame and cap it. Something like:
shake_push_budget = 6 -- max total push per frame
shake_push_used = 0
function capped_shake_push(r, amount)
local remaining = shake_push_budget - shake_push_used
if remaining <= 0 then return end
local actual = math.min(amount, remaining)
an.camera.shake:push(r, actual)
shake_push_used = shake_push_used + actual
end
Reset shake_push_used to 0 each frame in an early_action. Then replace an.camera.shake:push calls with capped_shake_push.
Total directional shake per frame would never exceed 6 (or whatever cap), regardless of how many orbs fire simultaneously.
Just add a variable to the shake module that is the cap, and change that to some value. Do it internally in the shake module for that particular function.

Current Build: Null Orb Swarm
20 empty orbs orbiting the player with random radii (16–128px due to greatly_increased_orbit_radius) and random speeds. No abilities on the orbs themselves — they're just bodies.
What makes it work:
orb_contact_damage = 1— Every orb deals damage on contact. 20 orbs orbiting = passive damage field. Walk into enemies and they melt. This is the orb build's baseline DPS.ability_copy— The player has fireball on mouse 1. Normally only the player would cast it.ability_copybroadcasts it to ALL 20 orbs — one click, 20 fireballs.null_conversion— Converts fireball from a caster-processed spell into raw null mana. Instead of 20 fireballs firing from the player (which would look like one fireball), each fires from its own orb's position. 20 orbs scattered across the screen = 20 fireballs from 20 different positions, all aimed at the mouse. Also turns them purple.Lance (right-click hold) — Orbs arrange in a line from player toward aim direction. 50% speed, turn rate limited. Turns your swarm into a spear — poke into enemy clusters at range. The spring dynamics make the transition fluid.
Wall (space hold) — Orbs arrange perpendicular to aim. 70% speed, faster turn rate. Sweep through groups by turning. Same spring system, different target positions.
Why it's interesting:
The three modifiers (ability_copy, null_conversion, orb_contact_damage) transform 20 inert orbs into a multi-purpose weapon system. Default orbit = passive area damage. Lance = directional spear. Wall = sweeping scythe. And every formation doubles as a firing position — click mouse 1 in lance formation and 20 fireballs fire forward in a line. Click in wall formation and 20 fireballs fire from a perpendicular spread.
The formations also compose with projectile modifiers. Add backshot and lance becomes a double-ended spear, wall gets a rear guard. Add nova and lance becomes 8 arms of orbs radiating outward. All through the same build_formation_angles function that the projectile system uses.
How does wall with backshot work, let me see
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Space for wall — 10 orbs in front, 10 behind. Right-click lance also gets the backshot (forward + backward spear).
Seems like everything works great. What are the other formations you mentioned before?
From our earlier discussion:
Whip — Orbs trail behind your movement path with delay. You CIRCLE things. Faster movement = wider sweep arc. Stationary = useless (orbs collapse on you). Most movement-dependent formation.
Concentrate — All orbs collapse to a single point at fixed distance ahead. You RAM into things. Maximum single-target DPS, zero coverage. Battering ram.
Scatter — Orbs deploy to fixed world positions and stay there. You PLACE AND LEAVE. Creates a danger zone you kite enemies through. Orbs stop following the player. When released, they spring back.
Oh yea, wall should have lower speed and lower turn rate than the lance, I forgot that.

Wall: 35% speed, turn rate 2 (vs lance: 50% speed, turn rate 3). Slower and heavier — you commit to the sweep.
Let's try whip, call it snake instead.
[Request interrupted by user]
Actually, because I made SNKRX, let's make the behavior of this formation work similarly to that game. Orbs trail you, while active, you always move forward and can only turn left and right to steer. Makes sense?
That makes perfect sense. While holding the snake ability: constant forward movement, left/right to steer, orbs trail behind you along your path like in SNKRX.
I need to:
- Add "snake" ability (hold activation)
- While active: override movement to constant forward + turn-only steering
- Store a trail of player positions
- Each orb targets a position from the trail based on its index (orb 1 = closest behind player, orb 20 = tail end)
The trail needs distance-based sampling so orbs stay evenly spaced regardless of speed. Does this sound right, or do you want something different about the movement/trail?
Seems right.

The problem is slot processing order — fireball (manual) is checked before snake (hold), so any_formation is still false when fireball is evaluated. I need to process hold abilities first:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Two-pass: hold abilities first (sets any_formation = true), then manual abilities (can now see the formation is active and auto-fire).
Let's make the trigger while channelling cooldown 4x the ability's normal cooldown
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Auto-trigger uses 4x cooldown (fireball: 2s instead of 0.5s). Manual activation still uses normal cooldown.
What are the other two formations?
Concentrate — All orbs collapse to a single point at fixed distance ahead. Maximum single-target DPS, zero coverage. Battering ram.
Scatter — Orbs deploy to fixed world positions and stay there. Creates a danger zone you kite enemies through. When released, they spring back to you.
Both concentrate and scatter can be collapsed into the same thing. A formation that sends orbs to a location and spreads them through that area with some distance between them. Using area modifiers this area can be made smaller (concentrate) or bigger (scatter).
That's clean — one formation, area modifiers control the spectrum from battering ram to minefield.
Base behavior: orbs deploy to a location and spread within a radius. slightly_increased_area makes the spread wider (scatter), decreased_area or no modifier keeps it tight (concentrate). Same modifier system, different emergent behavior.
For the target location — should it be:
- Aimed point (like windfield): fixed distance in the aim direction, turn rate limited
- Mouse position: deploy wherever mouse is, within a max range
And what should we call it?
Mouse position with very low speed and turn rate (lowest on all counts).

Perfect. Should any of the fan, parallel, etc modifiers work with this or not?
I don't think they naturally fit. Lance and wall are directional — they extend from the player in a facing direction, so fan/backshot/sideshots map cleanly onto that (more directions to extend in). Deploy is positional — you're placing orbs at a point. The directional modifiers don't have an obvious meaning.
You could force it — backshot = second deploy area behind you, nova = 8 deploy areas — but that splits 20 orbs across many zones, each with 2-3 orbs. That undermines deploy's identity of "put your orbs HERE, densely."
Deploy's knobs are the area modifiers (radius), and potentially count (more orbs = denser field at the same size). The directional modifiers are lance/wall territory.
How about the area modifiers, cascade, etc?
Area size (increased/decreased) — already working, the core deploy knob.
Cascade — yes, makes sense. Multiple deploy circles in a line from the target point. Splits orbs across them. You'd lay down a corridor of orbs instead of one cluster.
Magnetic area — strong yes. Pull enemies toward the deploy center. Enemies get sucked into your orb cluster and shredded by contact damage. Obvious synergy.
Growing/Shrinking — radius changes over time while held. Deploy spread out, slowly concentrate. Or start tight, gradually scatter. Interesting tactical dimension.
Echo — doesn't apply. Echo creates new effects, but deploy positions existing orbs. Nothing to repeat.
Moving/Homing zone — could move the deploy center over time, but it already has the slow-moving cursor. These would conflict or be redundant.
Cascade and magnetic feel like the strongest fits. Want me to implement either?
Cascade doesn't make sense for me, but magnetic and ghrowing/shrinking do, implement those

Done. Both modifiers work with deploy:
- Growing zone: deploy radius expands over time (30% per second). Orbs gradually spread out.
- Shrinking zone: deploy radius contracts (15% per second, min 25%). Orbs concentrate inward.
- Magnetic area: enemies within 2x deploy radius get pulled toward the center. Combine with contact damage for a gravity well.
Test with p1:add_modifier('magnetic_area') or p1:add_modifier('growing_zone').

Uh, the pull is way too strong, like it's being applied many times continually.
e:push() applies an impulse with spin/flash effects — calling it every frame is way too much. I should apply a gentle continuous force instead:

Still weak, are you sure this code setting velocity here is having any effect? If velocity is set elsewhere, then we should just add to some variable here and add that variable there. But I'm not sure where this code is and when you added it.
You're right — the seeker's update overwrites velocity with steering forces every frame. But the seeker already has pull_fx, pull_fy fields that get added to its steering forces. I should use those:
Edit (E:\a327ex\Orblike\main.lua)

Now it feeds into the seeker's steering system properly — pull_fx/fy are added to the force calculation in seeker:update and reset to 0 each frame.
Good, but that's too strong now.

OK, let's recap everything we've added, from abilities to modifiers
New Systems
Player Slots — Player has slots table like orbs. Can hold abilities and modifiers. Player modifiers apply globally to all orbs via p1:get_mods().
Orb Spring Movement — Orbs use a damped spring system on offsets from the player. orb_follow_frequency (20) and orb_follow_damping (0.8) control how they track targets. Player following is instant (zero lag), springiness only affects the orbit/formation dynamics. Orbs spawn at player and spring outward with effects (hit_circle, particles).
Formation System — orb_formation global controls how orbs compute their target positions. build_formation_angles() shared function computes directional arms from projectile modifiers.
Ability Tags — Each ability has a tags table. ability_has_tag(name, tag) helper to check.
Push Shake Cap — shake.push_cap limits total directional shake per frame (set to 12).
Formations (player hold abilities)
| Formation | Behavior | Speed | Turn Rate |
|---|---|---|---|
| Lance | Line from player in aim direction, orb_spacing between orbs |
0.5x | 3 |
| Wall | Line perpendicular to aim direction | 0.35x | 2 |
| Snake | Always moves forward, left/right to steer, orbs trail behind path | 1.0x | snake_turn_rate: 4 |
| Deploy | Orbs deploy to mouse area (slow-moving cursor), poisson disc distribution | 0.2x | 1 |
All formations compose with projectile modifiers (backshot, sideshots, nova, spreading, parallel) via build_formation_angles() — except deploy which uses area modifiers instead.

Do you see a way for us to simplify the system such that the player/orb distinction doesn't exist but we somehow still maintain the difference between global and local modifiers?
[Request interrupted by user]
Or do you think this difference is interesting and shouldn't be simplified?
I think the distinction is interesting and should stay. Here's why:
The player/orb split creates a genuine resource allocation tension that mirrors proven ARPG design. Player slots are your identity — what kind of caster are you? Orb slots are your loadout — what tools do you carry?
The orb build we've been designing is a perfect example: you spend player slots on orb_contact_damage, greatly_increased_orbit_radius, formations — things that make the orbs themselves your weapon. A normal caster spends those same player slots on backshot, increased_area, homing — things that make their abilities stronger. Same resource pool, fundamentally different builds.
If you collapse the distinction, every modifier is just in a bag and there's no structural reason to specialize. The question "do I invest globally or locally?" disappears.
The one thing I'd simplify: the API for adding things. Right now player:add_modifier and orb:add_modifier are separate functions with identical code. The slot format is the same ({type = 'modifier', name = ..., value = ...}). The only meaningful difference is where the slot lives — on the player (global) or on an orb (local). That's already clean enough. The implementation difference is just that p1:get_mods() gets merged into every orb's mods table, which is one line of code.
I don't care about how you simplify it internally, do whatever you wish. But let's make sure then that ALL modifiers work as expected. If we have spreading_multiple_projectiles on player it should apply to all orbs, regardless of which ability is cast. Is this currently the case? Let's test it, let's go back to 4 orbs, and 4 different projectile abilities (if we have that many), with projectile modifiers applied to player instead of each orb, so I can see if they're affecting things correctly.

We only have two projectile abilities: fireball and null_arrow. The others are melee/chain/area carriers. Let me set up 4 orbs with fireball and null_arrow (the two projectile ones), plus spreading on the player:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
4 orbs: orbs 1-2 have fireball (mouse 1), orbs 3-4 have null_arrow (key Q). Player has spreading_multiple_projectiles = 3 + backshot globally. Since p1:get_mods() is merged into each orb's mods in orb:activate(), both abilities should fire in a 3-way fan + backshot pattern.
Seems like it works. You'd say the player -> all orbs pipeline is correct and will always work for all modifiers in the future?
Yes, because the merge happens at one choke point — right at the top of the activate function's timer callback:
local mods = p1:get_mods()
for _, slot in ipairs(self.slots) do
if slot.type == 'modifier' then
mods[slot.name] = slot.value
end
end
Every ability activation starts by collecting player mods, then overlaying orb-specific mods on top. Any code downstream that reads from mods sees both. So any new modifier we add in the future will automatically propagate from player to all orbs — as long as the code that checks it reads from the mods table, which everything already does.
The only exception is modifiers that have side effects outside the activate function — like the orbit radius modifiers, which are checked in orb:new, or the formation response modifiers, which are checked in orb:update. Those read p1:get_mods() directly where they're used, which also works.
The one thing to be careful about: orb-specific mods override player mods with the same name (since they're written second). That's intentional — a per-orb homing would override a global homing — but could be surprising if someone expects them to stack. If we ever want additive stacking, we'd need to change the merge to add values instead of overwrite. But for now, override semantics are cleaner.
What about the ability copy modifier. In player, it copies the ability to all orbs. What should it do when it's inside a single orb?
When this orb fires, all other orbs also fire that same ability. It makes the orb a "broadcast source" — like a leader orb.
So orb 1 has fireball + ability_copy + homing. When orb 1 fires, all 20 orbs fire fireball. But only orb 1's copy has homing — the other orbs fire with their own mods (plus player globals). The source orb's local mods don't transfer to the copies.
This is different from the player version: player ability_copy broadcasts the player's ability. Orb ability_copy broadcasts that orb's ability. You could have multiple broadcast orbs with different abilities — orb 1 broadcasts fireball, orb 2 broadcasts null_arrow, rest are empty receivers.
Sure. Let's make sure we do this with a visual effect, though. The source orb fires, simultaneously a line goes from that orb to player, and then from player to all other orbs, then all other orbs fire the copy with their own modifiers.

Now test it — put ability_copy on one orb:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Orb 1 has fireball + ability_copy. Mouse 1 to fire: orb 1 fires fireball → line from orb 1 to player → player flashes → lines from player to orbs 2-4 → orbs 2-4 fire fireball. The override_ability guard prevents infinite recursion (copies don't re-broadcast).
Add different modifiers to the other orbs.
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Orb 1 fires fireball + broadcasts. Orb 2 fires the copy with homing. Orb 3 fires with pierce 3. Orb 4 fires with near_return. Each copy gets its own orb's modifiers on top of player globals.
After the original fires, each new projectile is fired with a small delay from each other, so they don't overlap. There should also be no lines from player -> orb. Just the one from orb to player for the original (default behavior).
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
No lines from player to orbs. Copies fire with 0.08s stagger between each. The original orb still gets its normal orb-to-player line (default behavior). Each copy orb also does its own default line when it activates via activate(ability_name).
Perfect, this works wonderfully. Let's try to make sure that always channel and trigger while channelling work with another channelled ability. What channelled ability do you think we should add?
A few options that would be distinct from what we have:
Aura — persistent damage field around the player. While channelling, enemies within radius take periodic damage. Simple to implement, obvious visual (reuse the area circle drawing), and with always_channel it becomes Righteous Fire (permanently on). With trigger_while_channelling it would auto-fire your manual abilities while you walk around burning things.
Drain — while channelling, pull life from enemies within range. Defensive channelling option. always_channel makes it a passive lifesteal aura.
Focus — while channelling, player can't move but ability cooldowns are halved. A turret mode. always_channel would be a weird permanent turret build.
Aura feels like the strongest fit — it's the most natural "always on" ability, and it pairs well with trigger_while_channelling for a walking death ball that auto-fires. It's also easy to implement since we already have area damage/tick code.
No, let's just do like a beam.

Right-click to hold beam. Orange line from player in aim direction, 150px long, turn rate 2, 0.4x speed. Damages enemies along the line every 0.15s.
Let's make the beam anime towards the target position, let's also break the beam line into segments. We'll want to implement homing where the beam will bend and curve (likely using bezier curves, or simply lots of segments). But first let's get the animation going.

The file E:\a327ex\Orblike\main.lua has been updated successfully.
Beam now animates from 0 to full length (fast lerp, ~0.08s to reach target), drawn as 16 segments. When released, length resets to 0 so it re-extends on next activation. The segments are straight for now — ready for per-segment bending when we add homing.
Perfect. Center of the beam should be white. Color of the skill should be progressively decreasing alpha rectangles to give it a sort of beam of light feel. The primary beam line should be something close to the slightly jagged line, not 100% straight, but also not too terribly jagged. Line particles should move forward along the beam's path on the sides of the white center randomly to give the beam a sense of power moving forward, you may create a new beam_particle class for this. Every tick of the beam it should also do effects on the player, like spring pull and particles and hit circle on source. Beam source should also be placed similarly to how sources for projectiles are, not the very center of the player.
This is a lot of visual work. Let me implement it piece by piece.
First, the beam_particle class:

2371→ -- Decay arc speed towards minimum

2375→ else
2376→ self.elapsed = self.elapsed + dt
2377→ local mult = 1/(1 + math.exp(20*(self.elapsed - 0.25)))
2378→ self.arc_r = self.arc_r + self.arc_base_speed*mult*dt
2379→ end
Let me find where the other effect classes are defined (after hit_effect):
Grep (^-- Effect: hit_particle)
2599:-- Effect: hit_particle (dark variant style)
Grep (^-- Effect: slightly_jagged_line)
2746:-- Effect: slightly_jagged_line

2749→-- Holds after animation, then blinks out.
2750→slightly_jagged_line = object:extend()
I'll add the beam_particle class right before the slightly_jagged_line section, then rework the beam drawing code:

Now rework the beam drawing and tick effects in the player update:

Here's what's in the beam now:
- Source: offset 8px from player center in aim direction (like projectiles)
- White center: core beam drawn as jittered segments (regenerated every 2 frames for crackle)
- Colored glow: 3 layers of colored rectangles with decreasing alpha (25, 50, 80) and increasing width outward
- Beam particles: spawn every 4 frames at random positions along the beam sides, travel forward
- Tick effects: every 0.15s — player spring pull, flash, hit_circle + hit_particles at source point
- Endpoint: colored circle at beam tip
Jaggedness should be slightly lesser, but also be... longer? It should happen as often as it does in along the beam. Everything else is quite perfect. Also no hit circle needed.

Edit (E:\a327ex\Orblike\main.lua)

The user clarified — jitter should happen less often along the beam. So fewer segments but same total beam length:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
10 segments — each jitter point covers a longer stretch of beam, so the wobbles are wider/smoother. Jitter amplitude is still 0.8px, so it's subtle but across longer segments.
Let's try with limited alpha behavior in both the particles and the beam edges, to try to match the rest of the game. In the rest of the game there's usually only 1 alpha visual effect, like the middle of an area, so let's try to keep it like that. The particles should avoid alpha, and the edges should only have 1 level to it perhaps, let's see what it looks like.

One glow layer at alpha 40, full-opacity beam particles. Matches the rest of the game's style.
I see, the way you're drawing the lines is on a per segment basis that leaves some gaps between segments. We probably want to construct a polygon or multiple and use that instead so it covers the whole beam length, specially since we'll eventually want it to curve. Also, let's try decreasing the center beam width. What is it now?
The center beam width is def.beam_width which is set to 3 in the ability definition.
For the polygon approach — you're right, drawing individual line segments leaves gaps at the joints, especially when segments are angled. A polygon strip would give continuous coverage and handle curves properly. I'd build a quad strip from the segment points, using perpendicular offsets for width:
For each segment point, compute two vertices:
left = point + perp * half_width
right = point - perp * half_width
Then draw quads between consecutive pairs.
Does the engine have polygon/triangle drawing, or should I use filled rectangles between points? Let me check the layer API.
Grep (polygon|triangle)
96:an:query_polygon(x, y, vertices, tags) -> [object, ...]
293:-- shape_type: 'circle', 'box', 'capsule', 'polygon'
352:collider:add_polygon(tag, vertices, opts?) -> shape
No polygon drawing on layers. Let me check the full API for any triangle/quad drawing:
Grep (layer:triangle|layer:quad|layer:polygon|layer:mesh)
No matches found
No polygon/quad drawing available on layers. The options are lines, rectangles, and circles. To avoid gaps, I could use layer:push/pop with rotated rectangles spanning each segment — essentially a rotated rect per segment that overlaps slightly at joints. Want me to go that route, or would you prefer to add a polyline/polygon draw function to the engine first?
Try decreasing the beam width to 2 first so I can see

Wait — the drone is a loop, so playing it every 0.1s would be wrong. Let me check the drone sound duration and use proper looping. Actually, an:sound_play plays a one-shot. For looping I should use an:music_play. But the sfx wrapper only does sound_play. Let me use music directly:

No loop parameter on sound_play. The timer approach is the way to do it. The current implementation works — plays on activation, replays every 2.5s while active, cancels on release.
Did you forget to load the lightmed version also? And is the duration of this sound exactly 2.5s?
Bash (ffmpeg -i "E:/a327ex/Orblike/assets/RPG3_ElectricMagic_Drone02Epic_Loop.ogg" 2>&...)
Duration: 00:00:02.70, start: 0.000000, bitrate: 492 kb/s
2.7s, not 2.5. Let me fix the interval and check the lightmed loading:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
The lightmed variant is loaded — it's in the sound_files table which iterates and loads _lightmed versions automatically. The sfx() function appends sound_mode (_lightmed) when playing. So sfx('beam_drone', ...) plays beam_drone_lightmed. The base an:sound('beam_drone', ...) loads the normal version (used for recording), and the loop at the bottom loads the lightmed version. Both are covered.
The cancelling isn't cancelling the sound immediately, there's a delay, and sometimes it doesn't cancel it at all. I believe you're cancelling the timer but not actually killing the sound?
You're right — timer:cancel stops the replay timer but the currently playing sound instance keeps going. There's no sound_stop in the API. This is exactly the use case for an:music — it can be stopped on demand. Let me switch back to music for the drone:

The third arg is channel, but it expects a number not a string. Let me check the API:

Channel is a number. Let me use channel 2 (assuming 1 is default):

Perfect, now let's apply various modifiers to beam and make sure they work. The most important one is homing. We want the beam to bend around as it finds targets, but not do such crazy bends that it looks wrong, it has to have like a minimum turn rate or something so that we can't get crazy tight turns that would make it look wrong. This means the homing for the beam has to find appropriate targets on top of drawing the bent line correctly. How do you suppose we should solve this? Let's talk first before doing anything.
The core challenge is that a beam isn't a projectile traveling over time — it's drawn all at once each frame. So we can't use the same lerp-toward-target approach. Instead:
Step-by-step ray simulation:
Each frame, "walk" the beam forward from source in small steps (2-3px each):
- Start at source, facing
p1.r - Each step: look for the nearest enemy within a forward cone (say ±45°). If found, steer toward it — but limited to a max turn rate per step (radians per pixel traveled, e.g. 0.03 rad/px)
- Advance forward by step size
- Record the point
- Repeat until we've traveled
beam_length
This produces a list of points that naturally curves toward enemies. The turn rate limit means:
- At 0.03 rad/px over 150px = max 4.5 radians total bend (~260°). Enough to curve into targets but can't do instant right angles
- The cone check prevents the beam from targeting enemies behind its current heading
- Multiple enemies get hit as the beam sweeps through a cluster
The beam drawing code already works with segments — instead of computing segments from a straight line, I'd compute them from the simulated path. The dash animation scrolls along the path length.
What makes this work:
- Turn rate per pixel (not per second) means the curve looks the same regardless of beam length
- No target = straight line (graceful fallback)
- Continuous re-evaluation at each step means the beam finds natural paths through groups
- Same approach extends to other path modifications later (zigzag, spiral, etc.)
Does this direction make sense, or would you change anything?
Sure, let's try it

Now I'll replace the beam drawing and damage section with the ray simulation approach. The simulation builds a path of points, then drawing and damage use that path:
Edit (E:\a327ex\Orblike\main.lua)

Now add homing to the test orb:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Right-click to fire the beam from orb 2. It simulates the path in 3px steps, steering toward the nearest enemy within a ±60° forward cone at 0.03 rad/px turn rate. Dashes and damage follow the curved path. Without enemies it's a straight line.
This works, but over multiple frames the way the line bends shouldn't be able to change so abruptly depending on how the path computes. We want to be able to sort of lerp (doesn't need to use actual lerp, the solution might use something else) between the paths of each frame so it looks more natural, does that make sense?
Yes — store the beam path on the orb and each frame lerp each point toward the newly simulated "ideal" position. The displayed path smoothly follows instead of snapping:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Now clear the stored path on deactivation:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Each frame: simulate the ideal path, then lerp each stored point toward the ideal at 12*dt speed. Source point always snaps to player. New points (beam growing) appear instantly, excess points (beam shrinking) are trimmed. The beam now smoothly curves toward new targets instead of snapping.
Perfect, let's make the beam's length higher. Actually, let's just add some beam length modifiers along the same line as other similar types of modifiers for other carriers.

Six tiers: slightly/increased/greatly increased (1.25x/1.5x/2x) and slightly/decreased/greatly decreased (0.85x/0.7x/0.5x). Beam is now 300px with greatly_increased_beam_length.
Let's make sure fan, parallel, etc, also work here
The beam currently simulates one path starting at p1.r. I need to run multiple simulations, one per angle from build_formation_angles, and handle parallel offsets too.

3 homing beams in a fan, each 300px long. All from the same orb, all curving independently toward enemies. Right-click to test.
The nature of homing as it is makes it so that they all have the same path. The homing has to take into account their "original" direction somehow and only bend parts of the beam that are close to enemies sort of? If you get what I mean
Right — all beams find the same global nearest enemy and converge. The fix: each beam should only home toward enemies that are near its current path, not the nearest enemy anywhere. A proximity radius instead of a global search:
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Now each beam only curves toward enemies within 40px of its current tip position. No forward cone needed — proximity alone keeps each beam in its own lane. Fan beams stay spread out and only bend locally when passing near an enemy.
The in-game recording feature is not capturing the looping beam sound for some reason.
The beam drone uses an:sound_play_handle() directly, which bypasses the sfx() function. The recording system only captures sounds played through sfx(). I need a handle-returning variant of sfx:

OK, what other modifiers should work with beam do you think?
From what we have and what makes sense:
Already working: homing, beam length (6 tiers), fan/parallel/backshot/sideshots/nova
Should add:
- Beam width (like area size tiers) — thicker beam = wider damage zone. Simple, directly useful.
- Tick rate — faster/slower damage ticks. Could reuse zone speed modifier names or create beam-specific ones.
- Homing turn rate — how tight the curves can be. Weaker/stronger homing already exist and could map here.
- Null conversion — beam fires from the orb's position instead of the player. Already exists as a modifier, just needs to work with beam code (currently hardcodes
p1.x/p1.yas source).
Interesting but more work:
- Beam terminus effect — spawn an area/explosion at the beam tip. "Cast on expire" from the design reference. The beam endpoint becomes a damage zone.
- Beam sweep — beam automatically rotates while held, sweeping an arc. Different from homing — it's a fixed-rate rotation, not target-seeking.
Don't apply: pierce (beams inherently pierce), chain (beams don't jump), return (beams don't travel).
Which ones do you want to tackle?
Let's do beam width, let's make tick rate general for both zones and beams, let's reuse the homing ones for how tight the curves can/can't be, and yea add null conversion. Beam sweep might be interesting with always channel, so let's add it. And let's try to make the cast on expire trigger be reused here to cast at beam end at a certain interval, every N beam tick rates.
That's a lot — let me do them all in one pass through the beam code. Let me first read the current state to plan the edits:

Here's everything added:
Beam width — slightly_increased/increased/greatly_increased_beam_width (1.5x/2x/3x), slightly_decreased/decreased_beam_width (0.75x/0.5x)
Tick speed (general, works for zones too) — slightly_increased/increased/greatly_increased_tick_speed (0.85x/0.7x/0.5x interval), slightly_decreased/increased/greatly_decreased_tick_speed (1.25x/1.5x/2x interval)
Homing turn rate — weaker_homing halves beam curvature (0.015), stronger_homing doubles it (0.06)
Null conversion — beam fires from orb position in purple, aims at mouse from orb
Beam sweep — beam_sweep = true makes beam rotate continuously at 1.5 rad/s. beam_sweep_speed = N for custom speed. With always_channel, it sweeps forever.
Cast on expire — cast_on_expire = N spawns an area at each beam tip every N ticks.

Dash and gap scale proportionally with beam width. A 3x wider beam gets 3x longer dashes and gaps.
OK, actually, let's not do that, and let's increase the beam width visually by flat amounts instead of multiplying it.

The beam itself looking thicker makes it look wrong. What's another way we could signify the higher area for beam collision?
A few options:
Just increase collision width, don't change the visual. The beam line stays thin. You know it's wider because enemies get hit further from the center. Hit effects communicate the reach.
Parallel guide lines. Two faint thinner dashed lines running alongside the center beam at the hitbox edges. Like a corridor.
Edge particles. Small particles occasionally spawn at the hitbox boundary, defining the edges without thickening the line.
Bracket markers. Small perpendicular tick marks at intervals along the beam showing the width — like measurement notches.
I'd lean toward option 1 — just widen the collision without changing the visual. The beam's identity is the thin dashed line. Making it look "bigger" fights that. The modifier is felt through gameplay (more enemies hit) rather than seen through a thicker line.
Let's try 2

Center beam stays at base width (2px). When beam_width modifiers are active, two faint parallel dashed guide lines appear on either side at beam_width * 1.5 offset, 1px wide, 60 alpha. Collision still uses the wider beam_width.
This works for me, now remove increased beam width

Perfect, list the things you added that we still have to test
From the batch we just added:
- Tick speed modifiers —
slightly_increased/increased/greatly_increased_tick_speedand decreased variants. Should work for both beams and zones. - Homing turn rate —
weaker_homing(gentler curves) andstronger_homing(tighter curves) applied to beam. - Null conversion on beam — beam fires from orb position, purple color.
- Beam sweep —
beam_sweepmakes beam auto-rotate. Pairs withalways_channel. - Cast on expire —

Which one first?
Let's try greatly increased tick speed

Tick rate goes from 0.15s to 0.075s (2x faster damage ticks).
Can we also increase the speed with which the looping sound is played based on tick rate, as well as the velocity of the dash lines? Both increase/decrease

The drone pitch should scale with tick speed ratio. The dash scroll speed (currently hardcoded 80) should also scale. Let me find where both are used:
Grep (an.time*80)
1107: local scroll = math.loop(an.time*80, stride)
I need to compute the tick speed ratio and use it for both the drone pitch and scroll speed. The ratio is def.tick_rate / tick_rate (base / modified — faster tick = higher ratio):

Perfect, now beam sweep, right? Let's try that with sideshots as well

The file E:\a327ex\Orblike\main.lua has been updated successfully.
3 beams (forward + sides) auto-rotating at 1.5 rad/s. Right-click to hold.
What other modifiers, if any, might we use to increase this sweep's turn rate? Should it scale with something like attack speed, movement speed, something else entirely?
I think tick speed is the most natural fit. It already represents "how active the beam is" — faster ticks = faster damage + higher pitch drone. Making it also affect sweep speed means one modifier controls the beam's entire operating tempo. Three effects from one knob.
The alternative is a dedicated beam_sweep_speed modifier, but that's another axis for the player to think about. Tick speed coupling keeps it simple: "this modifier makes the beam go faster" — everything about it speeds up together.
Long-term, a general attack speed or cast speed modifier would be the proper home for all of these (tick rate, sweep speed, cooldowns, cast time). But for now, tick speed doing double duty works.
Want me to couple sweep speed to tick speed ratio?
No, let's leave it for now. What was the last thing to test?
Cast on expire — cast_on_expire = N spawns an area at each beam tip every N ticks. Want to try it?
Cast on expire is a trigger, it should only spawn an area if its linked to an ability that does that. It should do whatever is linked to it on expire, which for beams happens to be the end point every N ticks.
Right — it's a trigger, not a hardcoded effect. The cleanest way with the current system: the orb has beam as its primary ability, and a second ability in its slots that gets fired by the trigger. cast_on_expire = N means "every N ticks, fire non-primary abilities at the expire point."
So the setup would look like:
lua
orbs[2]:add_ability('beam')
orbs[2]:add_ability('fireball') -- secondary, triggered by cast_on_expire
orbs[2]:add_modifier('cast_on_expire', 3) -- every 3 ticks
Let me update the beam code to fire secondary abilities instead of hardcoded areas:

I see — the old code still has the original fire_x, fire_y and r assignments at line 370-378. These need to be removed since fire() now handles that. Let me read more to find what to replace:

OK so the fire() function is already defined. Now I need to find the old timer callback that had the duplicate fire_x/fire_y/r code:

386→ if def.carrier == 'melee' then
387→ -- Melee wave: spawn areas sequentially from player toward mouse
The old fire_x/fire_y/r block at lines 370-384 is a remnant. It's inside... wait, let me look at the full structure. The fire() function I created starts at line 366 and contains the new fire_x/fire_y/r logic. But then there's the old mods collection at line 379. These are both inside fire(). The structure looks correct actually — fire() defines fire_x/fire_y/r, then collects mods, then the carrier code follows.
But the old timer callback self.timer:after(delay, function() ... end) is gone. I need to find where fire() ends and make sure it's called properly. Let me find the end of the activate function:

OK so end) at 843 closes the old self.timer:after(delay, function() which I replaced with local function fire(). So end) should be just end. And then I need to call fire() via the timer. Let me fix the structure:

Now secondary abilities fire through the normal activate path with the orb's own mods, from the beam tip position. Fireball will spawn as an actual projectile from the beam endpoint.
Very interesting. This is a more general thing that you likely just had to grapple with. But imagine the idea of a character or ability that casts any random ability at random. How would the current code be able to cope with that? It means that each ability should be modular enough that we can just call it in a more contextless manner while also applying any mods to it. Let's maybe try designing that specific ability? A random ability that picks one at random. This ability existing should ensure that the way we code every carrier is modular such that it would work here. First, tell me your plan to approach it, including how, if at all, your current solution for the fireball here applies.
The override_pos mechanism I just built is the right foundation, but it only works for projectile carriers right now. The other carriers (melee, self_area, aimed_area, chain) all hardcode p1.x, p1.y inside fire(). A random ability exposes this — if it picks frost_nova, the area spawns at the player regardless of fire_x, fire_y.
The plan:
Propagate
fire_x, fire_ythrough all carriers. Replace everyp1.x, p1.yinsidefire()withfire_x, fire_y. Self-area centers onfire_x, fire_yinstead ofp1. Aimed area computes mouse offset fromfire_x, fire_y. Chain searches for enemies nearfire_x, fire_y. Melee originates fromfire_x, fire_y.Handle
follow. Self-area currently followsp1. When firing fromoverride_pos, it shouldn't follow anything (the area stays at the fire point). So:follow = override_pos and nil or p1.The random ability itself is trivial once carriers are generic:
lua random_cast = { activation = 'manual', cooldown = 1, carrier = 'random', pool = {'fireball', 'fissure', 'frost_nova', 'arc', 'shockwave'}, }The carrier code just picks one and callsself:activate(random_choice, override_pos).The same fix makes cast_on_expire work for ALL abilities, not just projectiles. Beam tip fires frost_nova? Works. Deploy orb triggers arc? Works.
The work is step 1 — a pass through all carrier code in fire() replacing p1.x/p1.y with fire_x/fire_y. Want me to do it?
Regarding follow, let's imagine we have a trigger that makes a projectile cast frost nova or some zone, in that case it should follow the projectile carrier, right? Is your system handling things like this or not?
Not yet. Currently override_pos is a static {x, y, r} — just coordinates. A frost_nova fired from a projectile would stay at the point where the projectile was when it triggered, not follow it.
The fix is simple: override_pos becomes an activation context that can include a follow entity:
-- From beam tip (static position):
self:activate('frost_nova', {x = tip_x, y = tip_y, r = tip_r})
-- From a projectile (follows it):
self:activate('frost_nova', {x = proj.x, y = proj.y, r = proj.r, follow = proj})
-- Normal activation (no override, follows player):
self:activate('frost_nova')
Then in the carrier code, self_area would do:
lua
local follow_target = override_pos and override_pos.follow or p1
an:add(area(fire_x, fire_y, {follow = follow_target, ...}))
No follow in the context = area stays put (beam tip, deploy point). follow = proj = area tracks the projectile. No override at all = follows player as it does now.
The data structure supports it already — I just need to read override_pos.follow where follow is used. Want me to add this now while I'm doing the fire_x, fire_y propagation pass?
No, let's add that only once we add triggers such that this is possible. For now let's just make random work. I didn't see any issues with your plan, so let's try it.
Let me do the full pass — propagate fire_x, fire_y through all carriers, then add the random carrier.

Orb 1 has random_cast (mouse 1). Each click picks a random ability from the pool and fires it through the normal activate path with all the orb's mods applied. All carriers now use fire_x, fire_y so they work from any position.
Perfect, now let's go back to why we added beams, making sure the channel modifiers work properly with something other than the orb formation ones.
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
But wait — beam is a hold ability on an orb, not on the player. always_channel is checked in the player's hold ability processing. The beam hold is in the orb update. Let me add always_channel support to the orb's beam hold check:
Grep (hold.*beam)
1018- self:activate()
1019- self.cooldown = def.cooldown
1020- end
1021: elseif def and def.activation == 'hold' and def.carrier == 'beam' then
1022- if orb_input_down(self.slot) then
1023- if not self.beam_active and not self.beam_starting then
1024- self.beam_starting = true
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Now the beam should be permanently active (always_channel), and trigger_while_channelling should auto-fire fireball from all orbs via ability_copy + null_conversion. The beam counts as any_formation = true for the trigger... wait, beam doesn't set any_formation. Let me check what trigger_while_channelling checks:
Grep (trigger_while_channelling)
2013: local auto_trigger = mods.trigger_while_channelling and any_formation and slot.cooldown <= 0
3259:p1:add_modifier('trigger_while_channelling')
It checks any_formation which is set by the player's hold abilities. But the beam is on an orb, not on the player. I need a way to signal that a channel is active. Let me add a global:
Edit (E:\a327ex\Orblike\main.lua)

Trigger while channelling should trigger a secondary ability while the primary is channelling. In the formation case the primary channelling was the formation, here it will be the beam itself.
Right — it's per-orb. While the orb's primary (beam) is channelling, it auto-fires its secondary abilities. No need for global state. Let me remove the global and add it to the orb's beam code:

Add trigger_while_channelling after the source effects, before the trim. This fires secondary abilities from the orb's position on a cooldown:

Now update the test setup — beam + fireball as secondary on the same orb, with the channel modifiers:

Orb 1 has beam (primary, always channelling) + fireball (secondary, auto-fires every 2s via trigger_while_channelling). always_channel on the player keeps the beam permanently active. Fireball fires from the orb through the normal activate path with all its mods.
Is every 2s fixed or based on some other calculation?
Based on a calculation: fireball.cooldown * 4 = 0.5 * 4 = 2s. Same formula as the player-level trigger_while_channelling — 4x the ability's normal cooldown. So faster abilities trigger more often, slower ones less.
Let's do random_cast instead of fireball
Edit (E:\a327ex\Orblike\main.lua)
The file E:\a327ex\Orblike\main.lua has been updated successfully.
Beam + random_cast secondary. Every 2s it picks a random ability from the pool and fires it from the orb.
Perfect, it all works. Let's list all abilities, modifiers, triggers that we implemented this session.

Base directory for this skill: E:\a327ex.claude\skills\end-session
End Session Workflow
This skill is invoked from the same conversation where the work was done. You already have the full session context in memory — you do NOT need to read the transcript.
Step 1: Get Session Info
Ask the user: 1. Session title (max 30 characters). Examples: "Anchor Phase 10 Part 5", "Physics Arena Setup", "Timer System Fix" 2. Which project was this session for? Options: Anchor, emoji-ball-battles, orblike, other
Step 2: Write Summary
Write the summary from your conversation memory. You have the full session context — no need to read any files.
The summary should be thorough and detailed. Each major topic deserves its own section with multiple specific bullet points. Don't compress — expand.
Purpose: These summaries serve as searchable records. Future Claude instances will grep through past logs to find how specific topics were handled. The more detail you include, the more useful the summary becomes for finding relevant context later.
Format (this is just an example structure — adapt sections to match what actually happened):
# [Title] ## Summary [1-2 sentence overview of the session's main focus] **[Topic 1 - e.g., "Spring Module Implementation"]:** - First specific detail about what was done - Second detail - include file names, function names - User correction or feedback (quote if notable) - Technical decisions and why **[Topic 2 - e.g., "Camera Research"]:** - What was researched - Key findings - How it influenced implementation **[Topic 3 - e.g., "Errors and Fixes"]:** - Specific error message encountered - Root cause identified - How it was fixed [Continue for each major topic...] --- [Rest of transcript follows]Rules: - Be thorough — If in doubt, include more detail, not less. Each topic should be as detailed as possible while still being a summary. - Think searchability — Future instances will search these logs. Include keywords, function names, error messages that someone might grep for. - One section per major topic — Don't combine unrelated work into one section - Chronological order — Sections should match conversation flow - Specific details — Error messages, file names, function names, parameter values - Include user quotes — When user gave notable feedback, quote it (e.g., "k/d variables are not intuitive at all") - Weight planning equally — Research, proposals, alternatives considered, user feedback on approach are as important as implementation - Weight problems solved — Errors, root causes, fixes, user corrections all matter - Technical specifics — Include formulas, API signatures, parameter changes when relevant
Step 3: Get User Approval
Show the title and summary to the user. Wait for approval before proceeding. If they have corrections, fix them.
Step 4: Convert Transcript and Write Log File
# Find recent sessions by LAST MESSAGE TIMESTAMP (not file modification time) python E:/a327ex/Anchor/scripts/find-recent-session.py --limit 5The script shows sessions sorted by when they ended. The first result is the current conversation (since end-session was invoked here). Use it.
Convert the transcript to markdown and write the log file with the approved summary as header:
python E:/a327ex/Anchor/scripts/jsonl-to-markdown.py [SESSION_PATH] E:/a327ex/anchor.blot.im/logs/[slug].mdUse lowercase hyphenated slug derived from the title (e.g., "anchor-primitives-hitstop-animation").
Then replace the default header (
# Session YYYY-MM-DD...) with the approved title and summary.Step 5: Sync Context Files to Blot
cp E:/a327ex/.claude/CLAUDE.md E:/a327ex/anchor.blot.im/context/CLAUDE.md cp E:/a327ex/Anchor/docs/* E:/a327ex/anchor.blot.im/context/Step 6: Commit Project Repo
Based on which project was worked on:
For Anchor:
bash cd E:/a327ex/Anchor git add docs/ framework/ engine/ scripts/ reference/ git statusFor emoji-ball-battles:
bash cd E:/a327ex/emoji-ball-battles git add -A git statusFor orblike:
bash cd E:/a327ex/orblike git add -A git statusFor other projects: Ask the user which files to stage.
IMPORTANT — FULL SUMMARY IN COMMIT: The commit message MUST include the FULL summary from the log file. Read the summary back from the log file to ensure nothing is missing.
IMPORTANT — COMMIT METHOD: The summary contains backticks, special characters, and markdown that WILL break heredocs and
git commit -m. ALWAYS use the file-based method below. NEVER try a heredoc first — it will fail and produce a malformed commit that needs amending.Commit using a temporary file (extracts only the summary text, not the markdown heading or
## Summaryline):# Extract summary: skip line 1 (# Title) and line 3 (## Summary), take lines 4 onward until the --- separator awk 'NR>=4 && /^---$/{exit} NR>=4{print}' E:/a327ex/anchor.blot.im/logs/[slug].md > /tmp/commit_msg.txt # Prepend the title (plain text, no #) and append attribution sed -i "1i [Title]\n" /tmp/commit_msg.txt printf "\nGenerated with [Claude Code](https://claude.com/claude-code)\n\nCo-Authored-By: Claude <noreply@anthropic.com>\n" >> /tmp/commit_msg.txt git commit -F /tmp/commit_msg.txtStep 7: Push Both Repos
# Push project repo to GitHub git push origin main # Push Blot repo (logs and context are already there) cd E:/a327ex/anchor.blot.im && git add -A && git commit -m "[Title]" && git push origin masterStep 8: Confirm
Tell the user: - Commit hash - That GitHub push succeeded - That Blot push succeeded
ARGUMENTS: Orblike 6 Abilities 30 Mods
The user already provided the title: "Orblike 6 Abilities 30 Mods" and the project is Orblike.
Let me write the summary:
Orblike 6 Abilities 30 Mods
Summary
Massive session building out the Orblike orb system: player slots, formations, beam carrier, modifier propagation, and compositional ability architecture. Added 6 new abilities (beam, lance, wall, snake, deploy, random_cast), ~30 modifiers, and several new systems (formation angles, spring-based orb movement, ability tags, cast triggers).
Orb Build Concept & Player Slots:
- Established the "orb build" archetype: 10-20 empty orbs as primary weapons via contact damage, contrasted with normal builds using 4-5 ability-loaded orbs
- Created player slot system (
p1:add_modifier,p1:add_ability,p1:get_mods()) for global modifiers that apply to all orbs - Key tension: player slots spent on orb behavior (contact damage, formations, orbit radius) can't be spent on ability enhancement
orb_contact_damagemodifier makes orbs deal damage on sensor collision with enemies- Player mods merge into every orb's mods table via
p1:get_mods()at the top oforb:activate()
Orb Movement — Spring System:
- Replaced rigid parametric orbit (
x = player.x + dist*cos(speed*time)) with damped spring on offsets - Spring operates on
ox, oy(offset from player), so player following is instant (zero lag) while orbit dynamics are springy - Parameters:
orb_follow_frequency = 20,orb_follow_damping = 0.8 - Orbs spawn at player position and spring outward with hit_circle + hit_particles effects
- Adding new orbs doesn't affect existing orb positions (random offset, no redistribution)
- Tested various approaches to make orbs follow player tightly while moving: adjusting damping, adding player velocity, lerp_dt center tracking — ultimately the offset-based spring solved it naturally
Formation System:
orb_formationglobal controls how orbs compute target positions viaorb:get_target_offset()build_formation_angles(r, mods)shared function builds directional arms from projectile modifiers (spreading, backshot, sideshots, nova, parallel)- All formations compose with these modifiers — e.g., lance + backshot = double-ended spear, wall + nova = 8 walls
- Formations are hold-type abilities on the player with speed_mult and turn_rate
- Turn rate limits player rotation while formation is active (
math.clampon angular diff per frame)
Formation Abilities:
- Lance: line from player in aim direction,
orb_spacing = 14between orbs. Speed 0.5x, turn rate 3. Usesp1.rfor direction (not mouse directly, so turn rate applies) - Wall: perpendicular line to aim. Speed 0.35x, turn rate 2. Orbs distributed using
n_in_rowcalculation with lateral offset - Snake: SNKRX-style — always moves forward, left/right to steer. Records position trail, orbs follow trail at distance-based intervals.
snake_turn_rate = 4 - Deploy: orbs deploy to mouse area using
math.poisson_disc_circle(). Slow-moving cursor (60px/s toward mouse). Speed 0.2x, turn rate 1. Supports magnetic_area (periodic pulse pulls enemies toward closest orb), growing_zone, shrinking_zone, area size modifiers
Ability Tags:
- Added
tagstable to all ability definitions ability_has_tag(name, tag)helper function- Renamed caustic_arrow to null_arrow with
nulltag - Tags: fire, null, area, duration, projectile, earth, melee, wind, chain, lightning, ice, force, channeling, formation, orb, beam
Null System:
- Abilities with
nulltag fire from orb position instead of player (lore: casters can't process null mana) null_conversionmodifier adds null behavior to any ability — fires from orb, color becomes purple- Startup visual: player→orb line (reversed from normal orb→player), purple particles
- All carrier code uses
fire_x, fire_yvariables set based on null status
Beam Carrier:
- Hold-type ability on orbs with animated dashed line visual (scrolling dashes with rounded caps)
- Ray simulation: step-by-step path building (3px steps) for homing support
- Homing: proximity-based (40px radius, not global nearest), each beam in a fan curves independently
- Path smoothing: stored
beam_pathslerped toward ideal path each frame (lerp_speed = 12*dt) to prevent abrupt changes - Beam width modifiers use parallel guide lines instead of thickening the center line (user: "the beam itself looking thicker makes it look wrong")
- Tick damage via point-to-segment distance check along path
- Tick speed affects drone pitch (
sound_handle_set_pitch) and dash scroll speed - White flash on dashes near source, transitions to beam color
- Startup: orb→player line + delay, then beam extends with lerp animation
- Sound:
beam_caston startup,beam_dronelooping via newsound_handle_set_loopingengine function
Beam Modifiers:
- Beam length: 6 tiers (slightly/increased/greatly increased/decreased), multiplier-based
- Beam width: flat increments (+1/+2/+3, -1/-2), visual guide lines at edges
- Tick speed: general modifier for beams AND zones, 6 tiers
- Homing turn rate: very_weak (0.0075), weaker (0.015), base (0.03), stronger (0.04) — applied to beams, projectiles, and zones
- Beam sweep:
beam_sweepmakes beam auto-rotate at 1.5 rad/s - All projectile formation modifiers (fan, parallel, backshot, sideshots, nova) create multiple beams via
build_formation_angles()
Ability Copy Modifier:
- On player: broadcasts player's manual ability to all orbs simultaneously
- On orb: when that orb fires, all other orbs fire the same ability with 0.08s stagger delay
- Orb-level copy uses
override_abilityparameter, guarded byif not override_abilityto prevent recursion
Channel Modifiers:
always_channel: hold abilities stay active without input (checked in both player update and orb beam update)trigger_while_channelling: auto-fires secondary abilities at 4x cooldown while primary channels- Player-level: triggers during formations (checks
any_formation) - Orb-level: triggers during beam channelling (checks
self.beam_active) - Two-pass processing in player update: hold abilities first (set
any_formation), then manual abilities
Cast Triggers:
cast_on_expire = N: fires secondary abilities at beam tip every N ticks- Uses
orb:secondary_abilities()to get non-primary abilities from orb slots - Fires through
orb:activate(sec_name, {x=tip_x, y=tip_y, r=tip_r})— full activate path with position override
Generic Activate Refactor:
orb:activate(override_ability, override_pos)— fire any ability from any position- All carriers (melee, self_area, aimed_area, chain, projectile, random) use
fire_x, fire_yinstead of hardcodedp1.x, p1.y override_posskips startup effects (line, flash, particles) and fires immediately- Player feedback (spring pull, flash) suppressed when firing from override position
- Self-area
followset to nil when override_pos (area stays at fire point, doesn't follow player)
Random Cast Ability:
carrier = 'random', picks frompooltable, callsself:activate(chosen, override_pos)- Forces all carriers to be modular — any ability must work when called generically
- Works as secondary with
trigger_while_channelling: beam + random_cast = periodic random spells from the orb
Engine Changes (anchor.c):
- Added
sound_handle_stop(handle)— stops and cleans up a playing sound immediately - Added
sound_handle_set_looping(handle, looping)— sets looping on a playing sound - Both use
sound_handle_decodefor stale handle detection - Lua bindings:
l_sound_handle_stop,l_sound_handle_set_looping, registered in init - Framework wrappers:
an:sound_handle_stop(handle),an:sound_handle_set_looping(handle, looping)
Shake System:
- Added
push_capto shake module — limits total directional push per frame (set to 12) push_usedtracked per frame, reset inearly_update- Prevents screen shake explosion when 20 orbs fire simultaneously
Utility:
math.poisson_disc_circle(radius, n)— generates N evenly-spaced points filling a circle via rejection sampling with adaptive min_dist relaxationsfx_handle(name, vol, pitch)— likesfx()but returns a handle for later control, logs to recording systemadd_orbs(n)— spawn N empty orbsorb:secondary_abilities()— returns non-primary abilities from slots
Sound Assets Added:
beam_cast: RPG3_ElectricMagic_Cast02 (volume 0.42)beam_drone: RPG3_PlasmaMagicEpic3_P5_BeamLayer_Loop (volume 0.37)- Both converted to OGG + lightmed bitcrushed variants
Does this look good? Any corrections before I proceed?
Sure, looks good.
