Orblike Hideout 1

Summary

First major work session on the Orblike v2 rewrite (Anchor 2 framework) — ported v1 player movement, set up the edition shader system, fully ported the wall visual system (gradient, symbols, shader), refactored everything into a map class with proper cleanup, and prototyped a flat-wall layout for the hideout (later reverted pending design rethink).

Session start / context gathering:

Player port (player.lua):

Edition shader system:

Palette colors:

Wall system port — Phase A (boundary + collision):

Phase B step 1 — distance field visualization:

Phase B step 2 — colored gradient bake:

Phase C — edge lines:

Phase D — symbol scattering + per-pixel coloring:

Per-pixel symbol coloring:

Map class refactor (major architectural change):

F5 reload + texture leak fix:

plan.md updates:

Flat wall layout prototype (later reverted):

State at session end:

Let's get started on the new Orblike plan. Read it to get up to date on everything. There's also a new design mockup for UI in reference/ I think which we'll follow and improve as we go.

1    # Orblike — Implementation Plan
2   
3   Phase-by-phase plan for the Anchor 2 rewrite. See `design.md` for locked-in design decisions this plan implements.
4   
5   **Strategy recap:** Build the high-level shell (hideout, menus, inventory, orbs UI, map UI, run lifecycle) in Anchor 2 first. Port the combat (arena) from v1 last. The v1 code stays functional at `v1/` for reference and comparison throughout.
6   
7   **Pacing:** Incremental. Each phase should be testable on its own. User tests and gives feedback between phases. No chaining phases without check-ins.
8   
9   ---
10  
11  ## Phase 0 — Setup (done)
12  
13  - `v1/` holds old game + old framework, runnable via `run-v1.bat`
14  - Root holds v2 starter `main.lua` + v2 framework (`anchor/`), runnable via `run.bat`
15  - Assets duplicated into `v1/assets/` for isolation
16  - Design locked in `design.md`
17  
18  ---
19  
20  ## Phase 1 — Hideout shell
21  
22  **Goal:** A player walks around an empty room. Camera follows. ESC opens a stub menu.
23  
24  **Scope:**
25  - Port v1 player movement code (collider, input, sprite) to Anchor 2 idioms
26  - Rectangular room with wall colliders
27  - Camera follows player
28  - ESC toggles a stub "options" overlay (placeholder text, "press ESC to close")
29  - Background/floor rendering (solid color is fine)

1    # Orblike — Design
2   
3   High-level design for the Anchor 2 rewrite. Captures locked-in decisions. Not exhaustive — downstream details (specific items, NPCs, balance numbers) live elsewhere or will emerge during implementation.
4   
5   ---
6   
7   ## Concept
8   
9   A roguelike action RPG built on a PoE-style meta-loop. You play a sigil mage sponsored by the **Psyonian state** to cleanse regions of **null mana** corruption. Between cleansings, you return to a sponsored hideout to re-equip, craft, and plan the next expedition. Die, and everything resets — the state assigns a new mage to the post.
10  
11  The game is designed as a **platform for leagues**: modular map-level mechanics that vary gameplay style (bullet-hell, tower defense, survivors, etc.) while sharing the same hideout/inventory/map shell.
12  
13  ---
14  
15  ## Lore (brief)
16  
17  The Psyonian state sponsors null-mana cleansing. Mages with sigil/orb training are funneled into state-issued hideouts as independent contractors. The hideout is a Psyonian-run waystation: starter gear on loan, staffed NPCs, access to the teleporter network. Other NPCs at the hideout are state-employed support: a logistics/gear officer, a teleporter engineer, etc.
18  
19  Maps are places in the world saturated with null mana. "Map items" are teleporter beacons attuned to a specific place. The goal of a run is to track null mana back to its source and destroy it (the final boss).
20  
21  **Equipment visual identity** (from `reference/lore.md`): floating, robed, masked figure. Sigil glowing overhead. Orbs circling. Hands and feet ringed with magical bands.
22  
23  ---
24  
25  ## Core Loop
26  
27  1. **Spawn in empty hideout.** (New game or after death.)
28  2. **Approach gear NPC** → pick starter sigil / mask / orbs (one-time, diegetic).
29  3. **Approach map NPC** → select a map (starter map free from this NPC; others from your inventory).
30  4. **Portal appears in hideout** → step through → enter arena.

I've read design.md, plan.md, the current main.lua (just the empty Anchor 2 starter), and skimmed the SNKRX-grammar UI mockup. Here's where things stand:

Status: Phase 0 done. main.lua is a 19-line stub — black screen, one game layer, nothing else. Anchor 2 framework is copied into anchor/. v1 lives intact at v1/ for porting reference.

Next phase: Phase 1 — Hideout shell. Player walks around an empty room, camera follows, ESC opens a stub overlay. The phase explicitly validates that v1 movement code ports cleanly to Anchor 2 idioms (same code shape will power arena later in Phase 8).

UI direction: The Apr 18 mockups (mockup_ui_v2_snkrx.html, mockup_ui_elements.html, two book mockups) establish the SNKRX visual grammar — Pixelify Sans / Jersey 15 / Silkscreen fonts, dark warm palette (#2E2F33 bg, #EDE6D5 fg, saturated accents), checker background. These don't apply to Phase 1 directly (no UI yet beyond a stub ESC overlay), but they'll drive Phase 2 onward.

A few things worth deciding before I start writing Phase 1 code:

  1. Movement port scope. Lift v1's player+collider+input mostly verbatim (translated to v2 idioms), or take this as a chance to clean it up?
  2. Room dimensions / wall layout. Just a rectangular room matching screen size (480×270), or larger than the viewport so camera-follow is actually visible?
  3. ESC stub overlay. Just dim + "press ESC to close" text, or do you want the real options-menu layout sketched now (even with non-functional buttons) so Phase 2 has scaffolding?

Want me to open v1/main.lua and the relevant Anchor 2 docs next, then propose a Phase 1 structure?

We need to lift two things from Orblike, the movement system which should be pretty much exactly the same, including how the player is drawn, all the juice it has and so on. And then we also need to lift the wall gradient system. We want the hideout to be the size of the screen (no camera, at least not for now), and on the edges there are portions that have flat walls, other portions that have rocky polygons (like the current map generation there and more generally like rocks are done). We want to make sure that the wall system looks the same as it did in Orblike, but actually we can also improve it. I don't know if the design or plan documents have a plan for it, but in the last discussion about it (Orblike Design Plan), I believe that instance mentioned multiple ways we could improve the wall system to make the game look better. Maybe you could take a look at that log in anchor.blot.im/logs and find exactly what they said. I think those are the two most important points for us to start on. First gather information, don't start coding yet.

Got it. Let me gather information on movement, player draw, walls, and find that previous design discussion.

Let me delegate the deeper investigation in parallel — the design plan log and the v1 player/wall code are both substantial.

Wall Data Generation\n\nThe wall perimeter is built through these key functions:\n\n**Main Map Generation Function (Linear Map Example):**\n```lua\nfunction generate_linear_map(seed)\n  map_floor = nil\n\n  local rng = an.random\n  if seed then rng:set_seed(seed) end\n\n  local map_w = gw*3\n  local map_h = gh\n\n  -- Parameters\n  local top_margin = 28\n  local bottom_margin = 28\n  local side_margin = 32\n  local jitter = 6\n  local jitter_along = 2\n  local step = 20\n  local cr = 30  -- corner radius\n\n  local lx = side_margin\n  local rx = map_w - side_margin\n  local ty = top_margin\n  local by = map_h - bottom_margin\n\n  -- Build floor boundary CW in screen coords\n  local verts = {}\n\n  -- === Left closure: curved corner from left edge \u2192 top edge ===\n  map_gen_corner(verts, lx + cr, ty + cr, math.pi, 3*math.pi/2, cr, rng, jitter*0.5)\n\n  -- === Top edge: continuous jagged line, all 3 sections ===\n  map_gen_jagged_h(verts, lx + cr, rx - cr, ty, 1, rng, step, jitter, jitter_along)\n\n  -- === Right closure: curved corner from top edge \u2192 right edge ===\n  map_gen_corner(verts, rx - cr, ty + cr, 3*math.pi/2, 2*math.pi, cr, rng, jitter*0.5)\n\n  -- === Right edge: top to bottom ===\n  map_gen_jagged_v(verts, ty + cr, by - cr, rx, 1, rng, step, jitter, jitter_along)\n\n  -- === Right closure: curved corner from right edge \u2192 bottom edge ===\n  map_gen_corner(verts, rx - cr, by - cr, 0, math.pi/2, cr, rng, jitter*0.5)\n\n  -- === Bottom edge: continuous jagged line, all 3 sections (right to left) ===\n  map_gen_jagged_h(verts, rx - cr, lx + cr, by, -1, rng, step, jitter, jitter_along)\n\n  -- === Left closure: curved corner from bottom edge \u2192 left edge ===\n  map_gen_corner(verts, lx + cr, by - cr, math.pi/2, math.pi, cr, rng, jitter*0.5)\n\n  -- === Left edge: bottom to top ===\n  map_gen_jagged_v(verts, by - cr, ty + cr, lx, -1, rng, step, jitter, jitter_along)\n\n  -- Finalize: create chain shape + floor triangles\n  map_gen_finalize(verts)\n\n  -- Generate wall visuals\n  map_gen_wall_points()\n  map_gen_wall_distances()\n  wall_edge_wave_init()\n  wall_edge_wave_init_springs()\nend\n```\n\n### 2. Rocky Polygon (Jagged Edge) Generation\n\n**Jagged Horizontal Edge:**\n```lua\nfunction map_gen_jagged_h(verts, x1, x2, base_y, dir, rng, step, jitter, jitter_along)\n  step = step or 20\n  jitter = jitter or 6\n  jitter_along = jitter_along or 2\n  local sx = dir > 0 and step or -step\n  local x = x1 + sx\n  while (dir > 0 and x < x2 - step*0.5) or (dir < 0 and x > x2 + step*0.5) do\n    verts[#verts + 1] = x + rng:float(-jitter_along, jitter_along)\n    verts[#verts + 1] = base_y + rng:float(-jitter, jitter)\n    x = x + sx\n  end\nend\n```\n\n**Jagged Vertical Edge:**\n```lua\nfunction map_gen_jagged_v(verts, y1, y2, base_x, dir, rng, step, jitter, jitter_along)\n  step = step or 20\n  jitter = jitter or 6\n  jitter_along = jitter_along or 2\n  local sy = dir > 0 and step or -step\n  local y = y1 + sy\n  while (dir > 0 and y < y2 - step*0.5) or (dir < 0 and y > y2 + step*0.5) do\n    verts[#verts + 1] = base_x + rng:float(-jitter, jitter)\n    verts[#verts + 1] = y + rng:float(-jitter_along, jitter_along)\n    y = y + sy\n  end\nend\n```\n\n**Curved Corner Arc:**\n```lua\nfunction map_gen_corner(verts, corner_cx, corner_cy, start_angle, end_angle, r, rng, corner_jitter, steps)\n  corner_jitter = corner_jitter or 3\n  steps = steps or 6\n  for i = 0, steps do\n    local t = i/steps\n    local a = math.lerp(t, start_angle, end_angle)\n    local pr = r + rng:float(-corner_jitter, corner_jitter)\n    verts[#verts + 1] = corner_cx + pr*math.cos(a)\n    verts[#verts + 1] = corner_cy + pr*math.sin(a)\n  end\nend\n```\n\n**Rocky Polygon Parameters:**\n- `step`: 20 pixels (sampling interval along edges)\n- `jitter`: 6 pixels (perpendicular random offset from baseline)\n- `jitter_along`: 2 pixels (parallel random offset along edge)\n- `corner_jitter`: 3 pixels (radius variation for curved corners)\n- `cr` (corner_radius): 30 pixels\n\nThe algorithm generates a perturbed edge by stepping along the baseline (either horizontal or vertical) at regular intervals and adding random offsets perpendicular and parallel to the edge direction.\n\n### 3. Wall Data Structure\n\nAfter generation, the wall data is stored in the global `map_floor` structure:\n\n```lua\nmap_floor = {\n  vertices = verts,    -- flat array {x1, y1, x2, y2, ...}, stride 2, CW winding\n  triangles = triangulate(verts),  -- list of {i, j, k} index triples for rendering\n}\n```\n\n### 4. Wall Finalization\n\n```lua\nfunction map_gen_finalize(verts)\n  -- Clean up previous map\n  if map_boundary_obj then map_boundary_obj:kill(); map_boundary_obj = nil end\n  clear_arena_walls()\n\n  local n = #verts/2\n  local cx, cy = 0, 0\n  for i = 0, n - 1 do\n    cx = cx + verts[i*2 + 1]\n    cy = cy + verts[i*2 + 2]\n  end\n  cx, cy = cx/n, cy/n\n\n  -- Reverse CW \u2192 CCW for inward-facing chain normals\n  local local_verts = {}\n  for i = n - 1, 0, -1 do\n    local_verts[#local_verts + 1] = verts[i*2 + 1] - cx\n    local_verts[#local_verts + 1] = verts[i*2 + 2] - cy\n  end\n\n  -- Create collision body\n  local boundary = object:extend()\n  function boundary:new(lv, wcx, wcy)\n    object.new(self, 'map_boundary')\n    self.x, self.y = wcx, wcy\n    self:add(collider('wall', 'static', 'chain', lv, true))\n    self.collider:set_position(wcx, wcy)\n  end\n  map_boundary_obj = boundary(local_verts, cx, cy)\n  an:add(map_boundary_obj)\n\n  -- Triangulate floor for rendering\n  map_floor = {\n    vertices = verts,\n    triangles = triangulate(verts),\n  }\n\n  print('Generated map: ' .. n .. ' boundary points, ' .. #map_floor.triangles .. ' floor triangles')\nend\n```\n\n### 5. Gradient Implementation\n\nThe gradient effect uses a **distance field texture** approach. It's a 2-pass system:\n\n**Step 1: Compute Distance Field (Cached)**\n```lua\nfunction map_gen_wall_distances()\n  if not map_floor then wall_gradient_cache = nil; map_wall_gradient = nil; return end\n  local fv = map_floor.vertices\n\n  local min_x, min_y = math.huge, math.huge\n  local max_x, max_y = -math.huge, -math.huge\n  for i = 0, #fv/2 - 1 do\n    local x, y = fv[i*2 + 1], fv[i*2 + 2]\n    if x < min_x then min_x = x end\n    if x > max_x then max_x = x end\n    if y < min_y then min_y = y end\n    if y > max_y then max_y = y end\n  end\n  local margin = math.max(gw/2, gh/2) + 20\n  local bx0 = min_x - margin\n  local by0 = min_y - margin\n  local bx1 = max_x + margin\n  local by1 = max_y + margin\n\n  local scale = 8\n  local tw = math.ceil((bx1 - bx0)/scale)\n  local th = math.ceil((by1 - by0)/scale)\n\n  local n = #fv/2\n  local edges = {}\n  for i = 0, n - 1 do\n    local j = (i + 1) % n\n    edges[#edges + 1] = {\n      x1 = fv[i*2 + 1], y1 = fv[i*2 + 2],\n      x2 = fv[j*2 + 1], y2 = fv[j*2 + 2],\n    }\n  end\n\n  local fade = wall_gradient_fade_dist\n  local fade_sq = fade*fade\n  local distances = {}  -- normalized 0-1 per texel\n\n  -- Bucket edges by column ranges for fast lookup\n  local bucket_size = scale*8\n  local num_buckets = math.ceil((bx1 - bx0)/bucket_size) + 1\n  local edge_buckets = {}\n  for i = 1, num_buckets do edge_buckets[i] = {} end\n  for _, e in ipairs(edges) do\n    local ex_min = math.min(e.x1, e.x2) - fade\n    local ex_max = math.max(e.x1, e.x2) + fade\n    local b0 = math.max(1, math.floor((ex_min - bx0)/bucket_size) + 1)\n    local b1 = math.min(num_buckets, math.floor((ex_max - bx0)/bucket_size) + 1)\n    for b = b0, b1 do\n      local bucket = edge_buckets[b]\n      bucket[#bucket + 1] = e\n    end\n  end\n\n  for ty = 0, th - 1 do\n    local wy = by0 + (ty + 0.5)*scale\n    for tx = 0, tw - 1 do\n      local wx = bx0 + (tx + 0.5)*scale\n      local bi = math.max(1, math.min(num_buckets, math.floor((wx - bx0)/bucket_size) + 1))\n      local bucket = edge_buckets[bi]\n      local min_d = fade_sq\n      for i = 1, #bucket do\n        local e = bucket[i]\n        local dx, dy = e.x2 - e.x1, e.y2 - e.y1\n        local len_sq = dx*dx + dy*dy\n        local t = 0\n        if len_sq > 0 then t = math.clamp(((wx - e.x1)*dx + (wy - e.y1)*dy)/len_sq, 0, 1) end\n        local cx, cy = e.x1 + t*dx, e.y1 + t*dy\n        local dd = (wx - cx)*(wx - cx) + (wy - cy)*(wy - cy)\n        if dd < min_d then min_d = dd end\n      end\n      distances[#distances + 1] = math.clamp(math.sqrt(min_d)/fade, 0, 1)\n    end\n  end\n\n  -- Also create a grayscale distance field texture for the shader\n  local df_pixels = {}\n  for i = 1, #distances do\n    local v = math.floor(distances[i]*255)\n    df_pixels[i] = string.char(v, v, v, 255)\n  end\n  local df_tex = texture_create(tw, th, table.concat(df_pixels))\n\n  wall_gradient_cache = {\n    distances = distances, tw = tw, th = th,\n    bx0 = bx0, by0 = by0, bx1 = bx1, by1 = by1, scale = scale,\n    df_texture = df_tex,  -- grayscale distance field for shader\n  }\n  print('Cached ' .. #distances ..

8-- User proposed pincer approach: code the high-level portion (menus, between-maps, between-runs, UIs) in Anchor 2 first, then progressively port the low-level portion (combat, maps, abilities) from Anchor 1
9-- Claude assessed this strategy as sound and actually stronger than initially thought because the high-level portions don't exist yet — it's greenfield in the new engine, not a port
10:- Anchor 2's explicit procedural style (no tree, no hooks, IDs not pointers, poll not subscribe) is a better fit for menu/flow code than for combat code
11-- Eventual combat port will be substantial (uses every pattern v2 removed: tree hierarchy, tags, link, flow_to, action phases), but by then will have deep v2 fluency
12-- User's long-term vision: Orblike as a "homebase" game supporting PoE-style leagues (tower defense, survivors, etc.) plugged into the same map/run/progression shell

148-The high-level portions — menus, map selection, run structure, between-run flow — **don't exist yet**. This isn't a port, it's greenfield development. You're writing new code in the new engine, which is the easiest possible migration path. Meanwhile, the combat code (~7000+ lines of deeply Anchor 1-style Lua using trees, tags, link, flow_to) is the hardest thing to port. Deferring it is correct.
149-
150:Anchor 2's explicit procedural style is actually a **better fit** for the high-level flow code than it is for the combat code. Menu screens, map selection graphs, run state machines — these are naturally sequential, state-driven things that benefit from reading top-to-bottom with no hidden hooks.
151-
152-**The PoE leagues vision makes the architecture critical.** If the game needs to support radically different gameplay modes (tower defense, survivors, etc.) plugging into the same map/run/progression shell, then the high-level structure needs to be designed as a stable platform with clean extension points. Getting this right first, before the combat code muddies the water, is the right sequencing.

821-## What's good
822-
823:- **Hideout-as-hub** is elegant. It collapses "main menu + meta-game + run launch" into one coherent physical space. Much better than a menu system — every interaction is diegetic, and adding a new system is just "add an NPC."
824-- **"Inventory on right, action UI on left"** is a strong unification. Crafting, orb composition, trading, enchanting, whatever — they all feel the same. PoE itself has some inconsistency here (currency stash, heist, etc.) that Orblike can avoid by committing to the pattern early.
825-- **No meta-progression for now** is wise. Removes a whole category of design (unlock pacing, save migration, balancing meta vs. in-run power) and lets the core loop prove itself first.
--
930-You asked about connectivity. Three options, from simplest to richest:
931-
932:**(A) No connectivity, flat tier progression.** Just run any map at any tier you can afford. Higher tier = better loot. Simple, works, a bit flat.
933-
934-**(B) Region unlocking.** Start with 1-2 regions. Beating a region's boss unlocks the next. By end-game all regions unlocked. Lore fits (you're discovering new corrupted places).

Information gathered. Here's the picture.

1. v1 player system (port mostly verbatim)

Setup (v1/main.lua:7243): box collider 10×10, gravity off, fixed rotation; three springs (hit, shoot, move) all init at 1.0; base_speed = 100; color = blue; r (true facing) + visual_r (spin tween).

Update (v1/main.lua:7343): 8-directional WASD/arrow input → angle → velocity = speed*(cos, sin) straight to collider. Per-axis 0.8 friction multiplier when no key held. Rotation lerps toward mouse via math.lerp_angle_dt(0.99, 0.1, dt, ...).

Juice on movement (the part that matters):

Draw (v1/main.lua:7618): s = spring.hit.x * spring.shoot.x * spring.move.x, then rounded_rectangle(-w/2, -h/2, w, h, 2, color) at (x, y), rotation r + visual_r, scale sx*s, sy*s. Color override on flashing (white). No sprite — purely procedural rounded rect. Trail system + draw_health_ui are layered around it.

We can lift this almost line-for-line; the spring + timer modules are already in Orblike/anchor/.

2. v1 wall system (rocky polygon + distance-field gradient)

The pipeline (from generate_linear_map and friends):

  1. Boundary verts built CW: map_gen_jagged_h/v walks an edge in step=20 increments, perturbing perpendicular by jitter=6 and parallel by jitter_along=2. map_gen_corner does the rounded corners with radius jitter.
  2. map_gen_finalize: triangulates the floor polygon, builds a Box2D static chain collider for collision (CCW after reversal so normals face inward).
  3. map_gen_wall_points: scatters symbol positions (Poisson/grid/hex/etc.) outside the floor, each with (x, y, rotation, dist_to_edge).
  4. map_gen_wall_distances: precomputes a distance-to-edge field at scale 8 (so ~one texel per 8×8 px), bucketed for speed (~1–2s, cached). Stored normalized 0–1.
  5. map_gen_wall_gradient: bakes a small RGBA texture interpolating wall_bg_color → wall_bg_color_2 across the distance field. Re-bakes instantly on palette swap.
  6. wall_edge_wave_init + springs: subdivides boundary into ~5px segments, gives each a spring + outward normal so impacts ripple along the wall.

Each frame: draw the gradient texture once, draw floor triangles (using wall_edge_get_displaced so floor edges ride the wave), draw wall symbols (white — shader colorizes), draw edge lines (dashed or full) along the displaced boundary.

Palette is parameterized — 8 named palettes (blue/purple/red/green/orange/yellow/blue2/neutral), each with a wall + wall2 pair and a sym_darken value used by the shader.

3. Wall improvement notes from prior sessions

I want to be honest about what I found. orblike-design-plan.md (Apr 17) does not actually contain wall-improvement suggestions — I searched it for wall/gradient/rock/polygon/improve and only got passing references ("empty square room with wall collision" in the Phase 1 list).

The wall-improvement discussion you're remembering is probably in orblike-wall-visuals-ability-editions.md (Apr 4) or orblike-map-gen-wall-visuals.md (Mar 28). Those logs contain extensive iteration on the v1 wall system and notes on what was tried, kept, and rejected:

If you want the actual improvement suggestions you're remembering, I should dig into one of those two logs directly — say which one rings a bell (the Apr 4 one is the more recent visual pass). Or if you remember roughly what the suggestion was about, that'd narrow the search.

Plan suggestions before coding

Two open questions before I start writing:

  1. Hideout scope for Phase 1. Screen-sized, no camera — straightforward. But do you want the whole v1 wall pipeline lifted (gradient texture + symbols + edge wave + palettes) for the empty hideout? Or strip it to just generate_jagged → triangulate → chain collider → flat-color floor + edge line for now and layer the gradient/symbols/wave back in once we know the hideout shape?
  2. Mixed flat + rocky sections. You said some perimeter portions should be flat walls, others rocky polygons. v1 only has the all-rocky variant. Easiest is to make map_gen_jagged_h/v accept a jitter=0 mode (degenerates to a straight subdivided edge with same vertex stride), so the per-side calls in generate_linear_map can mix flat and rocky freely. That keeps the chain collider + gradient + wave systems unchanged. Sound right, or did you have a different layout in mind (e.g., one whole wall flat, one whole wall jagged, vs. interleaved within a wall)?

Ready to dig deeper into either log, or move toward a Phase 1 structure once you weigh in.

Ah, the post with the wall discussion is likely "Orblike Visual Design (not published)", you can only find it as a jsonl file I think.

Here's what I found:\n\n**Session File Location:**\n- File: `C:/Users/adn/.claude/projects/E--a327ex/0b31d43b-9e27-45a1-b644-48c76f7a90b2.jsonl`\n- Size: 293 KB\n- Modified: Apr 20 10:31\n- Status: This session was actually *searching for* the \"Orblike Visual Design\" wall improvements discussion but hasn't completed yet\n\n**The actual wall improvements discussion is documented in these published logs:**\n\n1. **`orblike-map-gen-wall-visuals.md`** (E:/a327ex/anchor.blot.im/logs/ - Mar 28, 524 KB)\n   - Detailed implementation of the wall system with distance-field gradients\n   - Contains suggestions like:\n     - **Removing the `+4` from X color** to simplify the wall symbol appearance\n     - **Drawing dashed lines for wall edges** to make them more pronounced (initially rendered in white)\n     - **Making symbols smaller** for better visual balance\n     - **World-based gradients instead of screen-based** \u2014 gradient should respond to distance from the actual wall edge, not just screen position\n     - **Rim glow along floor boundary** \u2014 3 layers of thick semi-transparent lines along the floor edge, bleeding outward, creating a world-space gradient brighter at the wall-floor junction, fading deeper into walls\n     - **Gradient encompassing the whole visual** \u2014 suggested that the gradient should be drawn OVER decorative symbols, not below them, so it tints everything uniformly\n\n2. **`orblike-wall-visuals-ability-editions.md`** (Apr 4, 268 KB)\n   - Refinements to wall visuals tied to ability edition system\n\n**Key Wall Improvement Techniques Mentioned:**\n- **Distance-field-based gradients** \u2014 computed once per map (~1-2s), cached, regenerated instantly on palette changes\n- **Shader-based coloring** \u2014 post-process shader detects white pixels (whiteness > 0.9) and replaces with gradient colors\n- **Multi-layer approach** \u2014 separate layers for rim glow, gradient overlay, floor, floor gradient, walls\n- **World-space vs screen-space** \u2014 gradients based on distance to wall edge rather than screen coordinates\n- **Complementary color palettes** \u2014 JoJo-inspired color schemes with gradients that \"pop\"\n\nThe unpublished Claude Code session (0b31d43b-9e27-45a1-b644-48c76f7a90b2.jsonl from April 20) references this prior work and is attempting to locate these exact suggestions to guide a v2 implementation of the hideout system."

Let me compile the final report:\n\n## Report: Wall Visual System Improvement Discussions\n\nThis Claude Code session extensively discusses improvements to Orblike's wall visual system. Here are the key suggestions and design directions proposed:\n\n### **Initial State Assessment (Line 83 - Assistant)**\n\nThe assistant identifies the current wall system as \"where the game has a signature\":\n- Distance-field gradient (`wall_gradient.frag`) from bright palette color at floor edge to dark palette2 color deep inside\n- Decorative symbols (X, wave, kanji, rune, etc.) scattered via Poisson/grid/hex distributions\n- Per-pixel recoloring of symbols from the distance field\n- Dashed or solid 2px outline at floor edge\n- Floor itself is a wash ~12% of the wall color\n\nThe assistant notes: **\"The wall gradient + symbol shader is the most distinctive thing you have. It's not a SNKRX element, it's yours. The per-pixel distance-field colorization of scattered symbols is a real signature.\"**\n\n### **User Response (Line 88 - User)**\n\nUser agrees: \"I also agree that the walls could similarly use more attention like the ability elements.\"\n\nThis establishes the direction: walls should receive visual treatment similar to elements (fire/ice/wind/lightning/poison/psy).\n\n### **Wall System as Environmental Identity (Line 680 - Assistant)**\n\nThe assistant recommends a **\"(1) atmospheric/moody with (4) mark-making\"** approach, stating:\n\n> \"Push the walls harder: more distinctive palettes per region, more evocative symbol sets, more subtle animation in the gradient. Let the combat primitives stay pills \u2014 their job is readability, not identity. The *environment* carries identity.\"\n\nKey proposal: **\"The third element [of Orblike's lineage] is the real differentiator. Nothing else looks like Orblike's wall regions \u2014 distance-field gradient coloring per pixel through hand-drawn symbols is a signature you've already built. That's the thing to lean into.\"**\n\n### **Specific Improvement Direction**\n\nThe assistant identifies the opportunity:\n\n**Four possible atmospheric directions for the game:**\n1. **Atmospheric/moody** \u2014 lean harder into walls, lighting, fog, depth. Each map a strongly characterized *place* with its own palette and symbol vocabulary. References: Hyper Light Drifter's saturated-on-dark, Downwell's extreme palette restraint.\n2. **Chromatic/jewel-like** \u2014 lean harder into editions and shader treatment. Every object is a small luxurious colored thing.\n3. **Kinetic/particle-dense** \u2014 action is the visual identity. Every ability leaves trails, screen fills with motion.\n4. **Calligraphic/mark-making** \u2014 push the wall-symbol system as the signature. Hand-drawn-feeling glyphs per region, inky textures.\n\n**Recommendation:** Pursue (1) and (4) together because \"that's where your unique asset (the wall shader) already lives.\"\n\n### **Concrete Proposals for Wall Enhancement**\n\nFrom the discussions, the specific improvements mentioned are:\n\n1. **More distinctive palettes per region** \u2014 rather than generic color assignment\n2. **More evocative symbol sets** \u2014 expand beyond X, wave, kanji; region-specific glyph vocabularies\n3. **More subtle animation in the gradient** \u2014 the static gradient can become dynamic (though with details preserved in later sections)\n4. **Environmental mood as identity carrier** \u2014 walls establish atmosphere, enemies/abilities remain readable primitives\n5. **Each map like a different illustrator's page** \u2014 visual distinctiveness between regions\n\n### **UI Canvas Integration (Line 688 & 700 - Assistant)**\n\nA critical secondary proposal: **use the wall shader on UI backgrounds**\n\n> \"Your wall-gradient + scattered symbols shader is Orblike's most unique asset. Nothing else looks like it. If **menu/inventory/hideout page backgrounds use the same shader**, the UI literally *lives in the same visual world* as combat. A hideout screen would feel like standing in front of a wall of scattered kanji with gradient lighting.\"\n\nThe mockup (line 700) demonstrates this: \"Background is a dark gradient with very sparse scattered X-symbol pattern \u2014 a cheap CSS approximation of the wall-shader treatment. In-engine it'd be the actual distance-field shader.\"\n\n### **Why This Matters (Line 680)**\n\nThe assistant positions this choice as identity-sharpening: \"Picking one [direction] to commit to \u2014 and letting the others recede to supporting roles \u2014 will sharpen the identity more than any new system.\" The wall system is identified as Orblike's *unique* visual asset compared to SNKRX and survivor-genre peers.\n\n### **No Code Snippets**\n\nThe session does not include GLSL shader code modifications for walls \u2014 it's purely strategic discussion of direction and application. The improvements are conceptual (more distinctive regional palettes, more evocative symbols, subtle animation) rather than technical shader rewrites.\n\n---\n\nThe session strongly establishes that Orblike's visual signature lives in the walls \u2014 not in the enemy pills (which are intentionally minimal for readability). The core improvement direction is **environmental depth through wall treatment**: push regional distinctiveness, symbol vocabularies, and mood, and extend that same visual grammar into the UI layer itself using the same shader."

Found and extracted. The "Orblike Visual Design" session (3ea3493f-...jsonl, 43MB, Apr 18–19) discussed walls strategically rather than as a list of specific shader changes. The relevant content:

What the previous instance said about wall improvements

Framing: the wall system was identified as Orblike's signature — the one thing nothing else has. Assistant's quote: "the wall gradient + symbol shader is the most distinctive thing you have. It's not a SNKRX element, it's yours. The per-pixel distance-field colorization of scattered symbols is a real signature." Your reply agreed walls deserve more attention, on par with the ability elements pass.

Recommended visual direction (out of four options it sketched — atmospheric/moody, chromatic/jewel-like, kinetic/particle-dense, calligraphic/mark-making): commit to (1) atmospheric/moody + (4) calligraphic mark-making together. Quote: "Push the walls harder: more distinctive palettes per region, more evocative symbol sets, more subtle animation in the gradient. Let the combat primitives stay pills — their job is readability, not identity. The environment carries identity."

Concrete improvement levers proposed:

  1. Region-specific palettes — not just the 8 generic palettes; each map is a "different illustrator's page" with its own color identity.
  2. Region-specific symbol vocabularies — the current scatter pulls from a global symbol pool. Per-region pools (kanji-heavy region, runic region, geometric region, etc.) would make places feel different.
  3. Subtle gradient animation — the gradient is currently fully static. Slow chromatic drift or breathing intensity gives the walls life without distracting from combat.
  4. Use the wall shader on UI backgrounds. This was the most actionable point. Quote: "If menu/inventory/hideout page backgrounds use the same shader, the UI literally lives in the same visual world as combat. A hideout screen would feel like standing in front of a wall of scattered kanji with gradient lighting." The mockup approximated this with CSS — in-engine it'd be the real distance-field shader.

What it didn't say: no specific shader/GLSL rewrites, no proposed new draw passes, no fix for any current visual bug. It's a strategic direction, not a punch list.

My read for what this means for Phase 1

The hideout is a wall-bounded space, and per the discussion it should be the first place where the wall shader gets to carry visual identity outside combat. So three layered options for how much of the wall system to bring up in Phase 1:

I'd lean toward middle for Phase 1 — the gradient is what carries identity, the symbols are extra, and the edge wave only matters when something hits the wall. Symbols + wave can come in a Phase 1.5 polish pass once the hideout shape is decided. But the previous session's strongest ask (UI backgrounds using the same shader) argues for lifting the full pipeline early so it's available when Phase 2 UI work starts.

Two things I want to confirm before any code:

  1. Pipeline depth for Phase 1: minimum, middle, or full?
  2. Mixed flat+rocky perimeter: how do you actually want this laid out? Some sketches:
    • Whole-side: top wall flat, side walls rocky (or any other per-side mix).
    • Per-section: each wall has flat segments and rocky segments interleaved (e.g., a flat "doorway" segment in the middle of an otherwise rocky wall).
    • Architectural: flat sections imply built/civilized (a Psyonian station wall) and rocky sections imply carved-out/natural (where the station meets the cave). The hideout is a built waystation, so maybe it's mostly flat with rocky breaks where the station opens onto raw stone?

The third option fits the lore (Psyonian-run waystation embedded in a corrupted region) and gives the walls meaning, not just visual variety. Want me to go that direction, or did you have something specific in mind?

Let me think more on the walls. For now, let's just do the player movement. Create a player.lua file and get it working mostly there, changing main.lua as necessary so I can test later.

Before writing, I need to understand Anchor 2's idioms — the v2 framework is quite different from v1 (procedural, IDs, no tree).

2     object — entity registry, kill queue, deferred destruction.

4     This is the foundation of Anchor 2's reference discipline. Entities are
5     plain tables with a numeric id; the global `entities` table maps id to
6     entity. Cross-entity references are stored as IDs and resolved via
7     lookup, so stale references are impossible (they just return nil).

I have the full picture of v2's API now. Here's the port plan — present it for review before writing.

Plan

player.lua — player = class() with :new, :update(dt), :draw(lyr), :destroy(). Mirrors v1 behavior:

main.lua changes:

Omitted for now (per your "just movement" scope):

One deviation from v1: v1 kept its movement code inline in the big update function. Splitting it out as player.lua with a class means you get p:update(dt) called from main instead of baked-in. That's the only structural change; the behavior is 1:1.

Does this look right? If yes, I'll write both files.

Go ahead.

Write (E:\a327ex\Orblike\player.lua)

File created successfully at: E:\a327ex\Orblike\player.lua (file state is current in your context — no need to Read it back)

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

The file E:\a327ex\Orblike\main.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Done. player.lua has the ported movement + juice; main.lua wires up physics, input bindings, palette globals, and spawns the player at screen center.

Test with run.bat — WASD or arrows should move, mouse position should rotate, you should feel the spin + squash on left/right presses and the bounce on stop. No walls, so the player drifts off-screen if you hold a direction long enough.

Player is not rotating towards the mouse direction correctly.

Let me check how mouse coordinates are actually handled.

Found it — mouse_position() returns game-space coords (480×270), not window pixels. I was dividing by scale which put the cursor at roughly (80, 45) instead of where it actually is. Fix:

The file E:\a327ex\Orblike\player.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Fixed — mouse_position() is already game-space. Try again.

Is the player color that you copied over correct? We will eventually use the edition system for most things, actually, so the color doesn't matter now. Actually, why don't we do that now? Since we'll also use it for the wall system, right? The wall system and the players and every other element in the game uses the same edition system colors, except the wall also adds on top of it the gradient, if I believe. But I'm not sure, I don't know the details of those systems that much.

Let me gather info on the edition system before recommending an approach.

Quick fact-check on the color: v1 blue is color(82, 179, 203) and v1 fg_color is color(222, 222, 222) — I used different values. So no, my colors weren't the v1 ones.

How the edition system actually works

The edition shader (assets/edition.frag already exists in your assets) is a fragment shader that recolors whatever's been drawn, based on a u_edition integer uniform. There are roughly three categories of mode:

In v1 the workflow is:

  1. set_draw_shader('assets/draw_shader.frag') once at startup — replaces the default fragment shader globally.
  2. Before each object/group of draws: shader_set_float(draw_shader, 'u_edition', N) and shader_set_float(draw_shader, 'u_time', time).
  3. After: reset u_edition to 0.

So an orb with edition 9 shimmers sapphire; the next orb with edition 7 shimmers emerald; the player normally has edition 0 (its self.color = blue) but can be cosmetically reskinned via edition.

How walls use this

Walls don't go through the edition shader for their gradient — that's baked separately as a distance-field texture using two palette colors. But there are also "edition wall palettes" defined (lines 5556–5566 of v1/main.lua) that derive wall + wall2 + sym_darken from each edition's hue. So when you pick an edition palette for a map, the walls get colors that match the edition. The scattered wall symbols also get colored per-pixel based on the wall color — that's a separate shader (wall_gradient.frag, also already in assets).

So the shared piece is the palette of hue centers. Walls and editions agree on which hue means "sapphire", which means "ruby", etc. They render it via different paths (edition: shimmer shader; walls: baked gradient + symbol shader).

My recommendation

Port the edition shader infrastructure now, in a minimal form that proves it works and sets the pattern. Concretely:

  1. Add set_draw_shader('assets/edition.frag') to main.lua and store draw_shader = get_draw_shader().
  2. Define time global gets refreshed each frame (already happens via sync_engine_globals).
  3. Player draws in white; before its draw call, layer_shader_set_float(game_layer, draw_shader, 'u_edition', player.edition) and 'u_time', time. After, reset to 0. Default player.edition = 9 (sapphire shimmer) so you can actually see the shader doing something.
  4. Replace my made-up palette globals with v1's actual values: blue = color(82, 179, 203), fg_color = color(222, 222, 222), etc.

That's the smallest possible "edition system is wired up" change. When walls come later, they'll use the same draw_shader for symbol coloring, and add the gradient texture + palette as separate concerns.

One caveat: I haven't verified that v2's set_draw_shader + per-object shader_set_float actually works the same as v1 — there's batching in v2's layer system, and per-object uniform changes only work if each layer_* call actually flushes or stores its own uniform state. If v2 batches across objects, all draws between renders would share one u_edition value. We'd find out by trying it. Worst case we apply the shader as a post-process to the whole layer with a single mode per frame, which is simpler but less flexible.

Want me to go ahead with that minimal port? Or look at v2's render/batching behavior first to know whether per-object uniforms will work?

There has been no logical changes to the way v2 works regarding layers, so it should work the same. Port the edition shader, make sure that anything we draw (player or not) can be drawn with it, and also make sure that the colors you port over are the same as the originals. We'll handle the wall later. But you mentioned that it has its own wall_gradient shader but you also said just that they use the same shader as the edition for symbol coloring? Which is it?

Let me check the actual wall shader setup before answering.

You were right to call me out — those were two different shaders. Let me clarify before coding.

Two shaders, two different jobs

edition.frag — replaces the default fragment shader globally via set_draw_shader. Every draw call passes through it. Reads u_edition per object: mode 0 = pass-through (original color preserved), modes 2–13 = animated gemstone shimmer, modes 14–22 = flat palette. The player, abilities, enemies, projectiles all use this. You draw white, the shader colorizes.

wall_gradient.frag — applied as a post-process shader specifically to the wall layer. Reads a precomputed distance-field texture, computes mix(wall_near, wall_far, distance) for the gradient, adds ripple effects, and detects symbol pixels (drawn in marker color 255,254,253) vs floor vs wall, recoloring each appropriately. Symbols have their own 9 coloring modes baked into this shader (HSV-based). Walls do not route through edition.frag.

The two systems share the palette of hue centers (so "edition 9 = sapphire = hue 0.6" matches "wall edition 9 has a hue-0.6-derived gradient"), and you pick a wall palette per map that visually matches an edition. But the rendering paths are independent.

So when I said "walls use the same shader for symbol coloring" — that was wrong. Walls have their own symbol coloring inside wall_gradient.frag. Only the concept (per-pixel coloring of white symbols) is shared.

Implementation plan

  1. main.lua: port the full v1 palette, set the edition shader as default, add a set_edition(lyr, mode) helper, add white color.
  2. player.lua: drop self.color, add self.edition = 9 (sapphire — visibly shimmery so we can confirm the shader is working), draw as white. Flash state uses edition 0 + fg_color.

Done. Edition shader is loaded as the default draw shader in main.lua, palette matches v1 exactly, and player.lua draws white at edition 9 (sapphire shimmer — you should see animated blue). Any future object can call set_edition(lyr, mode) before drawing and set_edition(lyr, 0) after. Flash state bypasses the shader to stay fg_color.

v1 had a change to the default draw shader that the engine uses for drawing everything, that should have been in the assets folder as the modified draw_shader that allows shaders like edition and wall_gradient to work as they do, that's how it works now too, right?

Good catch — let me check what v1's draw_shader.frag actually contains vs edition.frag.

You're right, I got it wrong. draw_shader.frag is the engine's default fragment shader with edition logic appended. It still does all the SDF shape rendering (rectangles, circles, polygons, rounded rects, sprites, AA) — those are the lines 37–82 for the SDF primitives and lines 228–299 for dispatching to them. Then it appends the apply_edition() function and calls it at the end of main(). Using edition.frag as the default drop-kicks all of that — no shapes would render at all.

edition.frag by itself is only applied as a post-process to entire layers (e.g. the effects layer in v1) where you just need to recolor an already-rendered texture.

Fix:

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

The file E:\a327ex\Orblike\main.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Fixed. Now the engine still does all its normal SDF shape rendering, and apply_edition() runs as a post-color transform at the end. Uses world position (vPos) for the organic field too, so the shimmer looks like it's in world space, not stuck to the sprite. Test again.

The player is being drawn as white, which means the shader isn't being applied. Are you sure the draw_shader is set in the original like you set it here? The draw_shader is a modification of the default one that the engine uses, so I'm not sure if it's loaded automatically on top of the original or if it has to be loaded like this.

Let me verify v2's engine handles set_draw_shader the same way.

Actually the shader is being applied — but I made a logic mistake. Drawing white and expecting edition 9 to produce a visible blue shimmer doesn't work, because of how apply_edition is written:

For hue-locked editions (2–13, including sapphire=9), the shader does:

White input has lightness 1.0. With l=1.0, you can't saturate anything — hsl2rgb of (0.6, 0.5, 0.945) comes out to roughly (234, 240, 248). That's basically white with an imperceptible blue tint.

This is by design: editions shimmer hue around whatever base color you give them, they don't pick a color from nothing. For edition-based coloring to be visible, the base color needs midrange lightness. v1's player draws with self.color = blue (which has lightness ~0.55) and applies the edition on top — the shimmer is the ±0.05 hue wobble around already-blue.

Two ways to make it visible:

  1. Match v1 exactly: base = blue, edition defaults to 0 (no shimmer). The shader's working but invisible until you assign a cosmetic edition. Faithful port.
  2. Default edition on for testing: base = blue, edition = 9. You'll see subtle hue drift around blue. Confirms the shader pipeline, but it's subtle because hue is already close to 0.6.

For a clearly-visible test, edition 12 (polychrome) cycles the full rainbow so you'd see the shader running unmistakably. Or drawing at medium grey (color(128, 128, 128)) + any hue-locked edition gives you a fully-saturated result.

My recommendation: restore self.color = blue, keep self.edition = 9 — matches v1's draw pattern and still gives visible shimmer. Want me to swap in polychrome (12) temporarily first just to prove the shader is live, then set back to sapphire?

Let's test polychrome since it's the easiest test.

Player is now blue base + edition 12 (polychrome). You should see the full rainbow cycling across the sprite over time — if it's still flat blue, the shader isn't wired up and we have a different bug to chase.

OK, it works. I think by default we can just draw everything as grey and then color everything using only the edition system. So blue = grey player + blue edition. Give me a key to go through all editions so I can see if each looks correct. And draw another bigger static rectangle on the side, no object attached to it, but it also goes through all editions with the player, its size should be big, like 80x80 or something.

Done. Press space to cycle 0→22 (wraps back). Expected sequence:

Current edition prints to console on each press. The 80×80 grey rect sits on the left at (40, 95)–(120, 175); both it and the player share the same edition each frame.

OK, for variety we should definitely have different underlying colors for the objects instead of just grey for everything because it makes the shaders look slightly different. So we'll keep doing what we were doing in v1, where each object has its own color but we color with edition on top. For now player is just blue, later when we add enemies they'll be red, and then abilities also have their own colors based on elements.

Now let's move on to bringing over the wall system. We need to do this on a step-by-step basis because this is one of the most important systems, both for how the generation algorithms will work, but also for how the game will look visually, so I want to make sure I understand how it works entirely. Tell me your plan for porting it over in detail before doing anything.

Plan: porting the wall system

Before any phase, let me lay out what the wall system actually is so we share a model. The "wall system" is really 7 subsystems layered on top of each other. Each does one thing, and each is testable in isolation.

The seven subsystems

  1. Boundary generation — algorithmic — produces a CW polygon of jagged edge vertices. Composed of three primitives: map_gen_jagged_h (horizontal jagged segment), map_gen_jagged_v (vertical jagged segment), map_gen_corner (rounded corner arc with radius jitter). Step size, perpendicular jitter, parallel jitter are tunable. Output: a flat array {x1, y1, x2, y2, ...}.

  2. Finalization — triangulates the polygon (for floor rendering) and creates a Box2D chain static collider (for player collision). Centers vertices around the polygon centroid. Output: map_floor = {vertices, triangles} and a static collider entity.

  3. Distance field — slow precompute (~1-2s). For each 8×8 px texel, find distance to nearest edge of the polygon, normalize to 0-1, store as grayscale texture. Bucketed by columns for speed. Output: wall_gradient_cache.df_texture (grayscale) + the raw distances array.

  4. Gradient texture — fast bake. Uses the distance field to interpolate mix(wall_color1, wall_color2, distance) into an RGBA texture. Re-baked instantly on palette swap. Output: map_wall_gradient.texture.

  5. Symbol scattering — generates positions for decorative symbols outside the floor polygon (so they appear on the wall area). Uses Poisson/grid/hex/etc. distributions. Filters out points too close to the floor edge. Output: wall_points = {x, y, rotation, dist_to_edge, ...} stride 4.

  6. Wall gradient shader (wall_gradient.frag) — applied as post-process to the wall layer. Does three things: (a) draws the gradient based on distance field, (b) detects symbol pixels (drawn in marker color 255,254,253) and recolors them with one of 9 modes, (c) computes ripple effects from impact origins. Reads multiple uniforms.

  7. Edge wave + springs — subdivides the boundary into ~5px segments, gives each a damped spring + outward normal. Wave coupling propagates impacts as ripples. Used for wall-deformation when something hits. Requires combat to be visible; for hideout this is optional.

Layering note (important for understanding)

The shader can do its symbol-detection trick because v1 draws everything to the same wall layer in a specific order: gradient texture (background), then white symbols on top, then floor triangles in the floor color, then edge lines. The shader reads each pixel and decides "this is a symbol" / "this is floor" / "this is wall" based on color matching. That's why we can't just draw symbols in their final color — they have to be drawn near-white as a marker, and the shader colorizes them per-pixel based on the gradient color at that location.

Proposed phases

I'd split the port into 5 incremental phases, each independently testable. We do them one at a time, you confirm each looks/feels right, then we move on.

Phase A — Boundary + collision (no visuals). Port map_gen_jagged_h, map_gen_jagged_v, map_gen_corner, map_gen_finalize. Build a rectangular jagged perimeter sized to the screen. Wire up the chain collider so the player can't escape. Floor renders as a flat color. Test: player hits walls, bounces correctly along the jagged edges. No gradient, no symbols, no shader. Why first: it's the foundation; everything else assumes valid floor geometry.

Phase B — Distance field + flat gradient. Port map_gen_wall_distances and map_gen_wall_gradient. Draw the baked gradient texture as the wall background. Pick a single palette (e.g. blue: wall_color = blue * 0.4, wall_color_2 = blue2 * 0.3). Test: the dark blue gradient appears around the perimeter, brighter near the floor edge, fading deeper into walls. No symbols, no shader yet. Why second: validates the distance field math + texture pipeline works in v2.

Phase C — Edge lines + clean floor. Add the dashed-or-full edge line along the boundary. Draw floor triangles in the floor color (not flat-color clear). Test: hideout starts looking like a real space — gradient walls, defined floor edge, clean floor color. Still no symbols/shader. Why third: rounds out the no-shader version; if we stopped here, the game would already look "Orblike-y."

Phase D — Symbol scattering + wall gradient shader. Port map_gen_wall_points (start with just one distribution like Poisson). Port wall_gradient.frag setup. Draw white symbols (just X for now) to the wall layer. Apply the shader as post-process. Test: symbols appear as colorized dots, gradient continues to work, layer composition is correct. Why fourth: this is the signature visual — the per-pixel colorized symbols against the gradient. It's the most complex visual setup, but everything underneath has been verified.

Phase E — Symbol variety + palette parameterization. Add the other symbol shape draw functions (triangle, circle, diamond, hash, etc.). Add the wall palette table so we can swap palettes. Add apply_wall_palette(). Test: can switch between palettes (blue, purple, red, etc.) and symbol types. Why fifth: content/tuning, not new mechanics. Lets us test the gradient look across the actual palette set the game will ship with.

Deferred to later (Phase F or beyond):

Open questions before starting Phase A

  1. Hideout perimeter shape. Phase A needs a perimeter generator. Three options:

    • (a) All-jagged rectangle, like v1's arena. Simplest port. Looks like an arena, not a hideout.
    • (b) Mixed flat + jagged, per your earlier idea. E.g., south wall flat (built/civilized — Psyonian station wall), north wall jagged (raw stone). I'd add a flat = true mode to map_gen_jagged_h/v that just steps without perturbing, so we can mix freely on a per-side basis.
    • (c) Defer the hideout shape. Use the v1 arena rectangle for Phase A–E to validate the system, then design the hideout shape as a final pass.

    I'd vote (c) — get the rendering pipeline right first, then design the shape. Otherwise we conflate "does the system work" with "does the layout work." But it's your call.

  2. Layer organization. v1 uses multiple layers (ground, ground_floor, ground_2) for the shader to do its symbol-detection trick. We don't have any of those yet — just game_layer. Do we:

    • (a) Add a wall_layer with the shader applied, draw walls to it, leave game_layer for player + non-wall stuff. Cleaner separation.
    • (b) Apply the shader to game_layer, accept that everything on that layer goes through it. Player will be detected as "wall pixel" by the shader and processed weirdly.

    Has to be (a). Just confirming you're OK with adding another layer.

  3. Hideout vs arena reuse. All seven subsystems are generic — they just take a polygon and palette. The hideout and arena will share 100% of the wall code; only the perimeter shape and palette will differ per-place. Sound right? (Means we should put the wall code in its own file, e.g. wall.lua, not inline in main.)

  4. Distance field cost. v1's distance field takes ~1-2s in pure Lua. For a hideout that doesn't change shape, this is a one-time cost at startup. We could later move it to C for instant generation, but for now: acceptable to eat the startup cost?

Let me know on these four, then I'll start Phase A.

  1. Sure, c seems reasonable. 2. The layer organization plus the specific way in which the trick is done is actually very confusing and we can probably simplify it. But yes, add wall_layer for now. 3. Yes. This should be in its own file, wall.lua, or map_generation.lua, or both, your choice. 4. This is a phase B concern.

Let me verify two things v2 needs to match v1: triangulation, and RNG.

Plan locked in. Phase A specifics:

File: map_generation.lua (new)

main.lua changes

Player still spawns at center (240, 135) which lands inside the floor.

Writing now.

Phase A done. map_generation.lua holds the boundary builders, triangulation, finalize, and the map_boundary collider class. main.lua calls generate_arena_rectangle() once at startup, draws floor triangles to wall_layer, player on game_layer above.

When you test you should see:

If the floor shape doesn't look right or the player passes through walls, that's the place to debug before Phase B.

Great looking code on the map generation file. Everything seems to work fine. The floor is a kind of dark blue that looks wrong and unlike v1, but we can fix that later. What's next?

Good. Floor color will become palette-derived in Phase E so that fits.

Let me check a couple v2 things before laying out Phase B.

Engine has texture_create(w, h, pixel_data_string) — undocumented but present. So we can port v1's pipeline almost verbatim.

Phase B plan

What it does:

Two passes that run once after the boundary is generated:

  1. compute_wall_distances() — for each texel in a grid covering the floor's bounding box (plus a small margin), find the minimum distance from the texel center to any edge of the polygon. Normalize to 0-1 by dividing by wall_gradient_fade_dist. Store as a Lua array. Also pack into a grayscale RGBA texture (we'll need this in Phase D for the shader, so we build it now). Bucketed by columns for performance — for our hideout this'll run in tens of ms, not v1's 1-2s.

  2. bake_wall_gradient() — fast bake using the cached distances. For each texel, output mix(wall_color, wall_color_2, distance) packed as RGBA. Build into a texture via texture_create. Re-bakeable instantly on palette swap.

Drawing:

In draw(), before the floor triangles, draw the gradient texture covering the bbox area. Floor triangles still go on top, so the gradient is only visible in the wall band (between polygon edge and screen edge).

Parameter tuning for hideout scale:

v1's arena was 3 screens wide, so it used wall_gradient_fade_dist = 250 (huge fade band) and a bbox margin of gw/2 + 20 = ~260. For our 480×270 hideout with 20px wall thickness, those numbers would produce no visible gradient — fade barely starts before going off-screen.

Sensible Phase B defaults:

Wall colors:

These are placeholders for Phase B testing. Phase E will derive them from a palette table.

File organization: New file wall.lua for the visuals side. Generation calls into wall.lua's compute_wall_distances + bake_wall_gradient at the end of map_gen_finalize. main.lua draws the gradient texture in the draw loop.

What you should see when Phase B works: A blue gradient surrounding the dark-blue floor — bright near the floor edge, fading to a darker blue-purple as it goes out toward the screen edge. The bg color (near-black) might show in the corners if the gradient bbox doesn't reach. The walls will start to look like Orblike walls.

Sound right? If yes I'll write it.

Can you write the first step only first and show it to me in the game? The visual texture that has the distances, the one that's generated by bake_wall_gradient. This way I can understand what's happening visually first.

Let me check how layer_draw_texture positions a texture in v2, then write step 1.

Step 1: distance field computation + visualization. I'll build the grayscale texture and draw it directly so you can see the raw distance values — black at the polygon edge, white deep into walls or floor interior. Floor triangles temporarily skipped so you see the full field both inside and outside the polygon.

Done. What you should see:

The texture is centered on the bbox using push(bx0+bw/2, by0+bh/2, 0, scale, scale) then draw_texture(0, 0) — the texture's tw × th texels are scaled up by 4 to cover the bbox. If positioning is off (e.g. shifted by half the texture), that's the texture-center-vs-top-left semantics being different than I assumed; easy fix.

Player still walks around on top so you can see the field relative to where you can actually go.

Game is crashing without an error, likely wrong value passed to a function that expects a C pointer to something.

Found it. v2's layer module has no layer_draw_texture wrapper — only layer_image (for image objects with .handle) and layer_texture (for raw texture handles). The global layer_draw_texture is the raw C function expecting a layer pointer; passing the Lua state table to it crashed.

Camera follows the player now. Bg stays screen-fixed; the wall gradient texture and the player both follow camera world space. Mouse-aim in player.lua reads from main_camera.mouse so rotation still tracks correctly.

Default follow uses smooth lerp (lerp=0.9, time=0.5) so the camera trails slightly. If you want it locked tight to the player, say so and I'll switch to camera_follow(main_camera, p, 1, 0) or similar.

[Pasted image/png]

Is this what it's supposed to look like? It's not generating anything beyond the initial screen, and there's no real gradient to speak of like in v1.

That's correct as far as the math goes — black at the polygon edge, white where distance ≥ fade_dist — but I picked tuning values that hide what the system actually does. Two issues:

1. Bbox too tight. I set margin = 20, so the distance field stops just 20px outside the polygon. Beyond that, the wall_layer is empty and the screen-fixed bg_color (black) shows through. That's why "nothing is generating beyond the initial screen" — the field literally doesn't exist out there.

2. fade_dist too small. I set it to 30, so the gradient saturates to white within 7-8 texels (~30px). v1 used fade_dist = 250 for its 3-screen-wide arena, so the gradient was extremely gradual — a soft halo that filled the entire wall area.

For our hideout to look like v1's walls, the bbox needs to extend WAY past the polygon (so there's wall to fade through), and the fade_dist needs to be much larger.

Also worth noting before we color it in step 2: the grayscale you see now is inverted from how the colored gradient will look. In step 2, distance 0 (black here) maps to wall_color (bright); distance 1 (white here) maps to wall_color_2 (dark). So the bright halo will hug the polygon edge and fade dark outward — that's the v1 effect.

Bumping both numbers:

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

The file E:\a327ex\Orblike\wall.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Try again. You should see the wall area extend ~250px in every direction beyond the polygon (visible by scrolling the camera with the player), and the gradient transition is now ~80px wide — much smoother. The polygon interior is still solid white because it's bigger than 80px from any edge, but the wall side will show the full fade from bright (at edge) to dark (deep in wall).

If it looks too dramatic or not dramatic enough, fade_dist is the dial.

[Pasted image/png]

This looks better. Let's increase the gradient transition by 1.5x.

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

The file E:\a327ex\Orblike\wall.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Done. fade_dist is now 120, so the gradient transitions over a wider band — each step on the gradient covers more distance, so the fade is gentler. Bbox margin is still 250 so there's plenty of room for the wider gradient to fully reach white before hitting the bbox edge.

Ok, what's the next step?

Step 2: bake the colored gradient texture from the distances, draw it instead of the grayscale, put the floor triangles back on top.

What changes:

  1. bake_wall_gradient() in wall.lua — runs after compute_wall_distances(). Iterates the cached distances array and produces an RGBA texture: each texel is mix(wall_color, wall_color_2, distance). Stored as wall_gradient_cache.gradient_texture.

  2. Wall colors in main.lua — wall_color = color_darken(blue, 0.4) (bright, near edge), wall_color_2 = color_darken(blue2, 0.3) (dark, deep). Placeholder values; Phase E derives these from a palette table.

  3. Drawing — replace the grayscale df_texture with the colored gradient_texture. Add the floor triangles back on top so the polygon interior shows floor_color instead of the gradient leaking through.

What you should see: bright-ish dark-blue hugging the polygon edge, fading to deeper blue-purple as it goes outward into the wall. Inside the polygon: the floor color solid. Past the bbox margin (250px out): bg black still hard-cuts.

Done. Test should show:

The hard bbox cut is the next thing we'll want to address eventually — either by extending the bbox even further, by making the bg color match the gradient's far color so the cut is invisible, or by fading the texture's alpha at its edges. Worth flagging but not blocking.

This step seems to be working, looks the same as in v1. What's next? Tell me first before doing.

Step / Phase C: edge line

What it is: a bright outline traced along the polygon's perimeter — between the floor and the wall gradient. In v1 this is what gives the floor a defined "edge" instead of just blending fuzzily into the gradient. It's the third visual layer in the wall sandwich (gradient → edge line → floor inside).

What I'd do:

  1. Add wall_edge_color = color_darken(blue, 0.6) in main.lua. This is brighter than the wall_color at the edge (blue × 0.4), so it pops as a highlight. Placeholder, palette-derived in Phase E.
  2. Add wall_edge_width = 2 (matches v1).
  3. Add draw_wall_edge(layer) in wall.lua — iterates map_floor.vertices consecutively and draws short line segments between each pair (the polygon is closed, so the last connects back to the first).
  4. In main draw, call it after the floor triangles, still on wall_layer. Player draws on game_layer above so won't be obscured.

Style: v1 supports dashed, full, none. Default in v1 was full (continuous line). I'll match — drop the dashed mode for now to avoid bikeshedding the dash pattern; can add later if you want it.

Visual you should see: a bright dark-blue line tracing the rocky polygon edge, with the wall gradient outside fading to dark and the floor color inside.

Sound good?

  1. Does that match v1's color? And yes, it's fine to drop dashed mode.

Yes, exact match. v1 sets wall_edge_color_base = p.wall * (p.edge_mult or 0.6) and for the blue palette p.wall = blue (full 82/179/203). So edge color = (49, 107, 122), which is what color_darken(blue, 0.6) produces.

Done. Bright dark-blue line tracing the rocky polygon edge, sandwiched between the wall gradient outside and the floor color inside.

Great, this works too. What's next? Tell me before.

Step / Phase D: symbol scattering — and a simplification

This is where v1 had the confusing layered marker-color trick you mentioned. Here's the simplification I want to propose.

v1's approach: draw scattered symbols in marker color (255,254,253), apply wall_gradient.frag to the wall layer as post-process, the shader detects "is this pixel a symbol?" by color match, recolors per-pixel based on distance field. This conflates symbol drawing, gradient drawing, floor drawing, and ripples all in one shader doing color-detection per pixel. Confusing.

My proposal: precompute each symbol's color in CPU when scattering, then draw the symbol directly in its final color. No marker trick, no per-pixel detection in shader, no wall_gradient.frag for now. We already have the distance for each scatter point — mix(wall_color, wall_color_2, dist) × (1 - darken) gives the same color v1's shader produces (mode 0, which is the most common mode anyway). The only thing lost is per-pixel color variation within a single 6px symbol — which is invisible in practice because symbols are tiny.

If you later want the per-pixel HSV variation modes (the 9 fancy modes in wall_gradient.frag), we add a real shader pass that samples the distance field. That's an additive change on top of this simpler base.

What I'd implement:

  1. Add helper point_to_polygon_edge_dist(px, py, vertices) to wall.lua — computes shortest distance from a point to any edge of a polygon. v1 has it; same algorithm as the distance field uses per texel.
  2. Add scatter_wall_symbols() to wall.lua — generates symbol positions using a jittered grid (simpler than v1's Poisson, looks similar, small bias toward regularity that's fine for first pass). Filters out points too close to the polygon edge (margin = (symbol_size + symbol_width) × 1.5). Stores wall_points = {x, y, rotation, normalized_dist} stride 4.
  3. Add draw_wall_symbols(layer) to wall.lua — for each point, push transform (translate + rotate), draw an X as two crossing lines, pop. Per-symbol color computed from wall_color, wall_color_2, normalized distance, and wall_symbol_darken.
  4. Globals: wall_symbol_size = 6, wall_symbol_width = 3 (v1 thicknesses for the X arms), wall_symbol_darken = 0.175 (v1's blue palette value).
  5. Draw order: gradient texture → symbols → floor triangles → edge line. Symbols underneath the floor so any near the boundary get hidden — defensive layering.

Deferred to later sub-step (D2 if needed):

Visual result: scattered Xes peppered across the wall area, each slightly darker than the gradient at its location, rotated randomly. The wall area starts to feel textured instead of just gradient.

One open question: symbol density. v1 uses spacing = wall_symbol_size × 6 = 36px between scatter points — meaning ~1 X every 36px square. Want to match that, or denser/sparser?

Sound good? And what density?

Match it. Later we want to add different types of ways in which the symbols are spread, how much they're spaced by, their size, shape, etc, but this will happen on a per map basis as we design the "feel" of each map. For now it's fine to just have a default for each of those for testing.

Implementing now.

Updated.

Great, what's next? Tell me first.

We've finished the meat of the wall system. Here are the natural next steps — your call which to do:

  1. Phase E: palette parameterization — bundle floor_color, wall_color, wall_color_2, wall_edge_color, wall_symbol_darken into a palette table, add apply_wall_palette('blue' / 'purple' / 'red' / etc.) that updates all of them and re-bakes the gradient + recomputes symbol colors. Small cleanup; enables per-map palette swaps later. Closes out the wall system cleanly.

  2. Fix the bbox hard cut — when you scroll the camera far out, you see a sharp edge where the gradient texture stops and bg_color starts. Fix options: extend bbox further, set bg_color = wall_color_2 so the cut is invisible, or alpha-fade the texture's outer rim. Quick polish.

  3. Phase 1 finish (per plan.md) — add the ESC stub overlay. Phase 1's deliverable was "walk around, hit ESC, see stub." We have movement and walls; ESC is missing. Cheap to add. Marks Phase 1 of the overall plan as done and primes us for Phase 2 (real UI primitives).

  4. Hideout shape design — the polygon is currently v1's arena rectangle. The actual hideout should have a deliberate shape — your earlier idea was mixed flat + rocky walls (Psyonian-built south wall, raw cave on north, etc.). This is the first design work that'll feel "hideout-specific" rather than "system-generic."

  5. Per-pixel symbol shimmer (deferred from Phase D) — port a stripped wall_gradient.frag pass for the 9 HSV symbol-coloring modes. Adds chromatic variation within each symbol. Visual richness, not blocking anything.

My pick: 1 then 3. Phase E closes the wall chapter cleanly so we don't have stale "TODO: palette-derived" comments scattered around. ESC stub then officially closes Phase 1 of the larger plan. After that, 4 (hideout shape) becomes the natural next conversation — and we'd have real palette infrastructure to use when designing that.

What do you want to do?

Let's actually get most of the important parts for the wall system working, regardless of which phase they're in. The most important one is making it so that symbols are also affected by the gradient, Currently they're a single color, right? They should also be affected by the gradient that's applied to the walls. Is this what's happening in v1 or something else?

Let me check shader binding details for v2 before describing the plan.

Yes — v1 does per-pixel coloring, ours does per-symbol (one color per X computed at scatter time from the symbol's center distance). For most symbols this looks fine, but symbols straddling a gradient transition look slightly "off" vs v1 because the whole X is one color even though one side of it is in a brighter zone.

Plan: per-pixel symbol coloring

Approach — same simplification logic from before. v1 uses one big shader on a combined layer with a marker-color trick to detect what's a symbol vs floor vs wall. We keep the simplification: a separate symbol-only layer with a small dedicated shader. The shader knows every fragment on the layer is a symbol pixel — just compute the gradient color at this fragment's world position and output it.

New asset: assets/wall_symbols.frag (~15 lines):

Lua changes:

  1. Add symbol_layer = layer_new('symbols') and load the shader in main.lua.
  2. Add point_in_polygon(px, py, verts) helper to wall.lua. Filter scatter_wall_symbols to keep only points outside the polygon (currently we keep both sides and rely on the floor draw to hide the inside ones — outside-only is cleaner since the inside ones are pure waste anyway).
  3. draw_wall_symbols now draws on symbol_layer, color = white. No per-symbol color computation. Delete recompute_wall_symbol_colors.
  4. In main draw, after drawing wall_layer, set shader uniforms on symbol_layer (u_cam, u_screen, u_color_near, u_color_far, u_darken, u_df_origin, u_df_size, u_dist_field), apply_shader, render, draw.

Draw order on screen: bg → wall_layer (gradient + floor + edge) → symbol_layer (per-pixel-colored symbols) → game_layer (player).

This puts symbols above the edge line, slightly different from v1 where edges are above symbols. Minor visual difference; can swap by drawing the edge on a separate layer last if you want v1 ordering exactly.

One thing to flag: the camera-following hideout means u_cam changes every frame, so the shader uniforms need to be set every frame (cheap — just a few layer_shader_set_* calls). That's the only ongoing cost.

Sound good?

This seems good to me.

Writing the shader and Lua changes now.

Done. Symbols now drawn white to their own layer, recolored per-pixel by wall_symbols.frag based on the distance field at each pixel's world position. Symbols inside the polygon are filtered at scatter time so we don't waste cycles drawing them.

When you test you should see Xes that visually blend smoother into the gradient — pixels of an X near the polygon edge come out brighter, pixels deeper into walls come out darker, all within a single X.

If the y-coordinate convention is wrong (symbols colored as if mirrored vertically) the fix is one sign change in the shader: swap (0.5 - TexCoord.y) to (TexCoord.y - 0.5). v1's formula assumes a specific FBO orientation — if v2 differs, that's the place to flip.

Perfect, looks good. Let's remove the stub from phase 1 in the plan file because we can just do that in the next section where we'll also do UI. Now the only thing left is figuring out the feel of the hideout itself via the map generation + the color and symbols we'll use. Before that, actually, we need to change main.lua to create a system that allows us to change "map" and that kills relevant objects between those changes so that we don't leak memory. We need to get on top of this first before the game spirals out in complexity. The only map we have now is the hideout, but we should still add it now. Reason through what would have to be done to get this done and tell me.

Let me handle the plan.md edit first, then walk through the map system reasoning.

Plan updated. Now the map system reasoning.

What "loading a map" actually involves

Walking through what a map currently produces in our code:

Owned by the map What it is Cleanup required
map_floor global table {vertices, triangles} nil-out
map_boundary_obj entity with Box2D static chain collider :kill() triggers :destroy() which destroys the collider
wall_gradient_cache.df_texture GL texture (grayscale distance field) texture_unload() — currently nothing frees this; this is the leak
wall_gradient_cache.gradient_texture GL texture (colored gradient) texture_unload() — same leak
wall_gradient_cache (table) distances + bbox metadata nil-out
wall_points list of scatter point structs nil-out
Palette globals wall_color, wall_color_2, wall_edge_color, floor_color, bg_color, wall_symbol_*, wall_gradient_fade_dist, etc. overwritten by next map's load

What's NOT map-owned (stays across map changes):

The two GPU textures are the actual memory leak. Lua tables get GC'd, but texture_create allocates a GL texture object that only texture_unload can free. Any solution must call texture_unload on both textures before nilling the cache.

Proposed structure

A map is a definition table holding everything that varies per location: visual params (colors, dimensions, symbol settings, fade dist), the polygon-generation function, and the player's spawn point. Maps are registered in a global maps table.

A load_map(name) function does the orchestration:

  1. Unload current map (kill boundary, free textures, clear globals)
  2. Look up the new map's definition
  3. Apply its visual params to globals
  4. Call its generate function (which builds the polygon, runs distance field, bakes gradient, scatters symbols — all the existing pipeline)
  5. Move the player to the new spawn point

File layout:

The maps/ directory anticipates more maps. For now only one entry.

Map definition shape

maps.hideout = {
  bg_color = color(17, 17, 17),
  floor_color = color_darken(blue, 0.18),
  wall_color = color_darken(blue, 0.4),
  wall_color_2 = color_darken(blue2, 0.3),
  wall_edge_color = color_darken(blue, 0.6),
  wall_edge_width = 2,
  wall_symbol_size = 6,
  wall_symbol_width = 3,
  wall_symbol_darken = 0.175,
  wall_gradient_fade_dist = 120,

  generate = function() generate_arena_rectangle() end,
  spawn_x = 240,
  spawn_y = 135,
}

load_map iterates these fields, sets each as a global (skipping generate/spawn_x/spawn_y which are handled separately). One source of truth per map; no per-map call to set 12 different globals manually.

main.lua becomes simpler

Currently main.lua hardcodes the palette globals and calls generate_arena_rectangle(). After the refactor:

require('map')
require('maps.hideout')
...
p = player(0, 0)
camera_follow(main_camera, p)
load_map('hideout')  -- moves player to spawn, builds wall pipeline

Palette globals disappear from main.lua; they live in the map definition.

The cleanup contract for future entities

Right now only map_boundary_obj is map-owned. Eventually maps will own NPCs, enemies, projectiles, dropped items, portals, etc. The natural extension: track them. Two patterns:

(a) Tag-based: entities call self:tag('map_owned') (or whatever) in their constructor; unload_current_map iterates all entities and kills those with that tag.

(b) Manifest: maintain a map_owned_entities list; entity constructors push themselves onto it; unload kills everything in the list.

(b) needs no changes to the entity model; just a global list. (a) needs a tag system. Anchor 2 is "no tag system" by design (per its docs), so (b) is more idiomatic.

For now, with only map_boundary_obj, just kill it explicitly. Add the manifest pattern when the second map-owned entity type appears. Premature abstraction is worse than a one-line nil-check.

Open questions before I implement

  1. Should unload_current_map be safe to call when no map is loaded? I'd say yes (just guard each cleanup with nil checks) — that way load_map can always call it as the first step without thinking.

  2. Spawn point semantics — spawn_x, spawn_y as numbers (simple) vs spawn = function() return x, y end (allows computed spawns, e.g., spawn at the center of the polygon). I'd start with numbers; switch to function later if needed.

  3. Do you want me to also enable a hot-reload key (e.g., F5 reloads the current map) for testing palette/symbol/feel changes quickly? Useful while we iterate on the hideout's feel. Cheap addition.

Tell me on these three and I'll implement.

Why don't we create a map class then and create a map instance instead of a table? Then we can have arbitrary objects inside the map, and move any updating and drawing that relevant to maps there. Later, when we add UI, we'll add it outside the map because none of the UI belongs to the map, despite using information from it. But the player, enemies, etc, and all other "gameplay" objects do belong to it, so they should be inside the map objects. Does this make sense? This makes it easier to destroy the object and create a new instance with the relevant values, this also means we don't have to use globals unless they really need to be globals.

But let's think about this carefully first. Is it better to do it this way or to do it the way you proposed?

Honest comparison.

The case for your approach (map instance)

State ownership is explicit. Right now wall_gradient_cache, wall_points, map_floor, palette colors — they're all globals. With a map instance, they become map.gradient_cache, map.wall_points, map.floor, map.wall_color, etc. Reading the code you can see in one place "everything this map owns." No accidental cross-map state.

Cleanup is centralized and contractual. map:destroy() is the single place that has to know "free these textures, kill the boundary collider, kill the NPCs." Forgetting one becomes a one-line bug in one location, not a leak scattered across globals.

Map-owned entities are tracked naturally. Add map.entity_ids = {}, push IDs in when spawning, iterate to kill on destroy. No tag system needed (which is good — v2 explicitly avoids tags). My earlier "manifest pattern" suggestion fits exactly into this.

Future-proofs for things we'll want. Multiple maps loaded simultaneously becomes cheap (e.g., previewing the next map in a portal, miniature minimap reference, smooth crossfade between hideout and arena). With globals, that's impossible without refactoring.

Less mental tax. When designing a new map you're reading one file (maps/hideout.lua) that fully describes that map's state and behavior. With globals you have to mentally trace which globals get set when, and whether they collide with system defaults.

The case for my original (table + globals)

Less refactor cost. wall.lua and map_generation.lua all operate on globals right now. Switching to "take a map instance" means changing every signature: compute_wall_distances() → compute_wall_distances(map), draw_wall_symbols(layer) → draw_wall_symbols(map, layer), etc.

Matches v2's procedural style more directly. v2 prefers free functions over methods. timer_new() + timer_update(t, dt) rather than t:update(dt).

That's about it though. The procedural style argument doesn't actually conflict with your proposal — we can do map_new(def) → map_update(m, dt) → map_draw(m, ...) and keep the v2 style while still gaining instance ownership. Doesn't have to be m:update() to gain the encapsulation.

My recommendation

Go with your approach. The refactor cost is real but acceptable — much cheaper to pay now while only the hideout exists than after we add arenas, leagues, NPCs spawned by maps, etc. The benefits compound as the game grows; the costs are one-time.

I'd lean toward class() syntax matching v2's pattern for entities (Player is class()-based, Collider is class()-based). So map = class() with :new, :update, :draw, :destroy methods. Internal wall pipeline (compute_wall_distances, etc.) stays as procedural functions that take the map as first arg — those are reusable algorithms across map types, not behaviors of a single map.

Player ownership question

Important edge case: the player is NOT map-owned. Per design.md, the player walks through portals between hideout and arenas, persisting across map swaps. They die on death (full game reset, separate concern from map swap).

So:

load_map() destroys old map, builds new map, and repositions the existing player to the new map's spawn point (p.collider:set_position(map.spawn_x, map.spawn_y)). Player itself isn't recreated.

What gets refactored

Confirm this and the player-stays-global call, and I'll do it. Also, your call on the F5 hot-reload key for tweaking hideout feel — useful while iterating on shape/palette, two lines to add.

Keep the palette globals in main.lua, like the SNKRX-theme colors (blue, yellow, etc), we'll use those in the future so we should keep it somewhere in the codebase for reference. The ones that belong to the map wall, floor etc colors can be moved accordingly. Everything else looks good.

Implementing now. This touches a lot of files; presenting after.

Done. Summary of what changed:

New files:

Refactored:

Cleanup contract:

Player ownership: stays global. load_map repositions the existing player to the new spawn point, zeroing velocity. Player and camera survive map swaps unchanged.

Test: run, walk around. Should look identical to before. The leak is fixed — calling load_map('hideout') again would now properly free the previous map's textures and collider.

Does process_destroy_queue call :destroy on killed objects?

Yes — looking at object.lua:

function process_destroy_queue()
  while #destroy_queue > 0 do
    local q = destroy_queue
    destroy_queue = {}
    for i = 1, #q do
      local e = q[i]
      if e.destroy then e:destroy() end
      if e.id then entities[e.id] = nil end
      e._dead = true
    end
  end
end

So entity:kill() queues, and process_destroy_queue calls :destroy() on each queued entity at the end of the frame. For our boundary, that triggers map_boundary:destroy() which destroys the chain collider.

But this raises an issue with my current map:destroy() that you may be circling: the collider isn't destroyed synchronously. map:destroy calls e:kill() which only marks for destruction. The collider stays alive in Box2D until the next process_destroy_queue() at end of frame.

Right now this doesn't matter — load_map only runs at startup, before any player movement, before any process_destroy_queue. But the moment we call load_map mid-game (portal traversal, region change, etc.), there's a window where:

  1. load_map('arena') runs
  2. current_map:destroy() queues old boundary for kill — collider still alive
  3. map(maps.arena) creates new map → new boundary collider added to physics world
  4. Both old and new boundary colliders are now in the physics world
  5. Player bounces off whichever segment is closer
  6. End of frame: process_destroy_queue fires, old boundary destroyed
  7. From next frame on: only new collider, fine

The fix is to drain the queue between destroy and create:

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

The file E:\a327ex\Orblike\map.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Now load_map works correctly mid-game too: old colliders are gone before new ones arrive. The end-of-frame process_destroy_queue() in update() still runs as normal for entities killed during gameplay (combat deaths, etc.) — this just adds an extra immediate drain at the map-swap moment.

I wasn't even getting at that, but seems reasonable. Give me a key to kill the current map and also load a new hideout.

F5 reloads the hideout — destroys the current map (kills boundary, frees both gradient textures, drains the queue so the old collider is gone) then builds a fresh one (new polygon seed → slightly different jagged perimeter, new symbol scatter, new bbox). Player gets repositioned to spawn each time.

Useful for verifying no leak (you can hammer F5 and watch memory stay flat) and for eyeballing how variable the random generation is.

Game crashed on F5. Likely to do with some C function, I'd guess the texture one.

Yes, it's texture_unload — but the bug is in the engine, not our Lua. Here's the chain:

Calling texture_unload on a texture_create result crashes on the free() because that pointer is into Lua-managed memory, not malloc'd.

So our textures (created via texture_create for the distance field + gradient) can't be safely unloaded with the current texture_unload. F5 → first call to texture_unload(gradient_cache.df_texture) → free on a Lua userdata pointer → crash.

Fix

The cleanest fix is to make l_texture_create behave the same as l_texture_load — return light userdata pointing to a malloc'd Texture, registered. Then texture_unload works uniformly for both.

In E:/a327ex/Anchor/engine/src/anchor.c around line 4910, replace:

    Texture* ud = (Texture*)lua_newuserdata(L, sizeof(Texture));
    *ud = *tex;
    free(tex);
    return 1;

with:

    // Register for cleanup on shutdown
    if (texture_count < MAX_TEXTURES) {
        texture_registry[texture_count++] = tex;
    }
    lua_pushlightuserdata(L, tex);
    return 1;

This makes texture_create return the same shape as texture_load. texture_unload's existing registry removal + texture_destroy(tex) then runs correctly (glDelete + free on a real heap pointer).

Want me to apply this and rebuild the engine?

Yes.

Done. Engine rebuilt with the texture_create → lightuserdata fix, copied to Orblike. F5 should now reload the hideout cleanly without crashing — both gradient textures get properly freed in texture_unload.

Seems to work. Add this as a task to do before we start the next phase in the plan file, but we should build a way to actually track memory usage accurately for the engine and the game.

Read (E:\a327ex\Orblike\plan.md)

20   ## Phase 1 — Hideout shell
21  
22  **Goal:** A player walks around an empty room. Camera follows.
23  
24  **Scope:**
25  - Port v1 player movement code (collider, input, sprite) to Anchor 2 idioms
26  - Rectangular room with wall colliders
27  - Camera follows player
28  - Background/floor rendering (solid color is fine)
29  
30  **Validates:**
31  - Anchor 2 framework works in Orblike's resolution/scale setup
32  - v1 movement ports cleanly to v2 idioms (important — same code shape will power arena later)
33  - Basic rendering + camera + input loop works
34  
35  **Deliverable:** Run the game, walk around inside the room.
36  
37  ---
38  
39  ## Phase 2 — UI primitives
40  
41  **Goal:** Reusable text/button/panel primitives we'll use for every UI downstream.
42  
43  **Scope:**
44  - Text rendering helpers (positioned text, centered text, colored text)
45  - Button (rectangle + text + hover/press states + click callback)
46  - Full-screen UI pattern (covers screen, dims hideout behind, closable)
47  - ESC opens an options menu (graphics/audio/keybinds stubs, resume, quit)
48  - UI input focus / event capture (while UI open, hideout doesn't receive inputs)

Edit (E:\a327ex\Orblike\plan.md)

The file E:\a327ex\Orblike\plan.md has been updated successfully. (file state is current in your context — no need to Read it back)

Added. Slotted between Phase 1 and Phase 2 with the rationale (the texture_create bug as the prompting case), the scope split between engine-side counts and Lua-side counts, and a concrete validation hook (hammering F5 keeps everything flat).

Ok, now the last task before we end this session. Let's make sure we find the right feel for the layout. First, we need to add a specific generation algorithm for it. Let's just do a mix of straight walls with more rocky looking portions. It should never be the case that we have a wall on top or bottom entirely, like you mentioned before. It should be always a mix of walls and normal rocks. First, decide on the number of wall sections, random between 3 and 5 is good for start I think (this is for all sides, not 3-5 per side). Then the walls should be far apart enough from each other that they never come close to overlapping. You may also decide if you want a wall to be a corner, which might give it a nice look. Let's start with this first, see if you can get it right, and then we'll iterate.

Implementing now. I'll add emit_side (a generic helper) to map_generation.lua, and generate_hideout (the hideout-specific layout) to maps/hideout.lua.

Done. F5 now generates a fresh hideout each time with a mix of flat and rocky walls.

Algorithm summary:

What you should see on F5:

Iterate from here — likely tuning candidates are min_wall_len/max_wall_len, min_gap, corner_buffer, and n_walls range. Or adding the corner-spanning wall variant if it'd add visual interest.

Bigger side on the walls, and immediately following each wall the rockiness (jitter) around it (on both sides) is higher and then decreases progressively as it gets away from the wall. This will increase the delta between rock vs. wall which will make it standout more.

Two changes — bigger walls in the placement, and a per-vertex tapered jitter in the rocky emission.

The file E:\a327ex\Orblike\maps\hideout.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Done. Two changes:

Bigger walls: min_wall_len 40 → 60, max_wall_len 100 → 120. Still fits within the short side (170 - 2×20 = 130 available), so rejection sampling still resolves cleanly.

Tapered jitter: emit_side now takes jitter_low / jitter_high / jitter_decay instead of one jitter. Per rocky vertex, computes distance to the nearest wall edge in the segment (not to corners — only walls trigger the taper), then linearly interpolates between jitter_high (at distance 0) and jitter_low (at jitter_decay or beyond).

Defaults for hideout: jitter_low = 6 (same baseline as before — far from walls looks the same), jitter_high = 14 (more than 2× normal — wild right next to walls), jitter_decay = 40 (~2 step intervals worth of taper).

F5 to see the new look. If the contrast isn't strong enough, bump jitter_high further; if walls feel too long, reduce max_wall_len.

[Pasted image/png]

I drew what I want kind of. At least one side of the wall should have a rock formation that is kind of a bump that then slowly tapers off. The other side of the wall can continue as normal. However, when a wall appears, it should appear higher than it would normally, by higher I mean more inwards by some value compared to the rest of the generation, and then on one of the sides it also has the rock formation which goes even higher before tapering off. I don't actually want the jitter change, I want this instead, however it may be achieved. Does it make sense or is it too vague?

Got it — clearer now. Let me restate to make sure I understand:

Reverting the jitter taper and implementing the inset + tapered bump:

The file E:\a327ex\Orblike\maps\hideout.lua has been updated successfully. (file state is current in your context — no need to Read it back)

Done. Summary of how it works:

Wall inset: every wall is pushed wall_inset = 20 px inward from the rest of the perimeter. The wall vertices sit at that depth.

Per-wall bump direction: each wall gets a random bump_dir of -1 (bump on the rocky portion before the wall) or +1 (bump on the rocky portion after the wall). Always exactly one side bumped.

Bump shape (linear-up, linear-down):

On the non-bumped side: rocky offset is just baseline (0). The wall's last vertex at offset 20 → next rocky vertex at offset 0 → that's a 1-step (~20 px) drop, giving the sharp angle visible in your sketch.

Inward direction is computed per side automatically: rotate the side's CW walk direction 90° CCW. So top side bumps go down-onto-the-floor, right side bumps go left, etc. — always pointing into the polygon interior.

Tunable dials per the parameters at the top of generate_hideout. Likely things you'll want to tweak after looking: wall_inset (how recessed walls are), bump_peak (how dramatic the peak), bump_length (how gentle the taper).

Hmmmm, this isn't it. Revert all changes back to normal. Normal is before we added the notion of walls at all.

By walls I mean the flat walls.

Reverted. maps/hideout.lua calls generate_arena_rectangle(m) directly again with no flat-wall logic. emit_side removed from map_generation.lua. Back to the all-rocky perimeter we had before the wall feature was added.

Let's end the session here, I need to think more about how I want the hideout to look, actually. Let's call this Orblike Hideout 1.

Launching skill: end-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 for the session title (max 30 characters). Examples: "Anchor Phase 10 Part 5", "Physics Arena Setup", "Timer System Fix", "Thalien Lune Design".

Determine the project yourself from your session context — you know which repo(s) were worked on, which files were created/modified, and where they live. No need to ask. See Step 6 for the list of known project roots; if the session touched something outside the list, infer the root from the paths you actually edited.

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 (Claude + Cursor; see script). Same script lives in Anchor2:
python E:/a327ex/Anchor2/scripts/find-recent-session.py --limit 5
# or: python E:/a327ex/Anchor/scripts/find-recent-session.py --limit 5

The 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/Anchor2/scripts/jsonl-to-markdown.py [SESSION_PATH] E:/a327ex/anchor.blot.im/logs/[slug].md
# or: python E:/a327ex/Anchor/scripts/jsonl-to-markdown.py ...

The same script auto-detects Claude Code JSONL vs Cursor/Composer agent JSONL (~/.cursor/projects/.../agent-transcripts/...). For Composer sessions, use find-recent-session.py (it merges both sources) and pick the [cursor] line for the current chat.

Use 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/

When the session was Anchor2 (optional):

cp E:/a327ex/Anchor2/.claude/CLAUDE.md E:/a327ex/anchor.blot.im/context/CLAUDE_ANCHOR2.md

Step 6: Commit Project Repo

Identify the project repo(s) worked on this session from your own context — you already know which repos were touched and which files changed. For the common projects, here are the canonical staging commands:

Project Root Stage command
Anchor E:/a327ex/Anchor git add docs/ framework/ engine/ scripts/ reference/
Anchor2 E:/a327ex/Anchor2 git add framework/ engine/ arena/ reference/ scripts/ docs/ .claude/
emoji-ball-battles E:/a327ex/emoji-ball-battles git add -A
orblike E:/a327ex/orblike git add -A
thalien-lune E:/a327ex/thalien-lune git add -A

For a project not listed, infer the root from the files you actually created or modified this session and stage those. If multiple candidate roots look valid, ask the user which files to stage.

cd into the project root, stage, run git status to verify before committing.

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 ## Summary line):

# 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.txt

Step 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 master

Step 8: Confirm

Tell the user: - Commit hash - That GitHub push succeeded - That Blot push succeeded

ARGUMENTS: Orblike Hideout 1

Here's the proposed title and summary:

Title: Orblike Hideout 1

Summary:

# Orblike Hideout 1

## Summary

First major work session on the Orblike v2 rewrite (Anchor 2 framework) — ported v1 player movement, set up the edition shader system, fully ported the wall visual system (gradient, symbols, shader), refactored everything into a map class with proper cleanup, and prototyped a flat-wall layout for the hideout (later reverted pending design rethink).

**Session start / context gathering:**
- Read Orblike/plan.md, design.md, main.lua (19-line stub), and recent UI mockups (mockup_ui_v2_snkrx.html, etc.)
- Discovered "Orblike Visual Design" was an unpublished jsonl session at `C:/Users/adn/.claude/projects/E--a327ex/3ea3493f-73fa-4cd0-9a19-7a7ee28aae9c.jsonl`
- Extracted wall improvement notes from that session: identified walls as Orblike's signature, recommended (1) atmospheric/moody + (4) calligraphic mark-making direction, suggested using wall shader on UI backgrounds
- Investigated v1 player code (player:new at line 7243, update at 7343, draw at 7618) and v1 wall pipeline (boundary generation, distance field, gradient, symbols, edge wave)

**Player port (player.lua):**
- Created `player = class()` with `:new(x, y)`, `:update(dt)`, `:draw(layer)`, `:destroy()`
- Direct port of v1 movement: 8-directional WASD/arrows → angle → velocity, base_speed=100, 0.8 friction per axis
- All v1 juice preserved: visual_r spin tween (±π over 0.2s on left/right press), squash tween (sx,sy → 0.8 over 0.05s, then → 1.0 over 0.4s), spring 'move' pull on stop bounce
- Box collider 10×10, dynamic, gravity_scale=0, fixed_rotation=true
- Three springs (hit, shoot, move) all init at 1.0 with default freq=5, bounce=0.5
- Mouse rotation via `math.lerp_angle_dt(0.99, 0.1, dt, ...)` toward `main_camera.mouse.x/y`
- Initially used `mouse_position()/scale` — bug, removed division (mouse_position returns game-space coords)

**Edition shader system:**
- Discovered `assets/edition.frag` is a standalone post-process shader, but `assets/draw_shader.frag` is the engine's default fragment shader replacement with edition logic appended
- Set `set_draw_shader('assets/draw_shader.frag')` in main.lua, captured via `draw_shader = get_draw_shader()`
- Helper: `set_edition(layer, mode)` sets `u_edition` and `u_time` uniforms
- Debugging: drew player white expecting edition 9 (sapphire) shimmer — invisible because hue-locked editions preserve input lightness, so white in = near-white out
- User reverted to v1 pattern: each object has its own base color, edition shimmers around it
- Tested polychrome (12) to confirm shader pipeline works
- Added space-key cycling through editions 0-22 with debug rect — user later removed this

**Palette colors:**
- Defined SNKRX-theme reference globals in main.lua: bg_color=(17,17,17), fg_color=(222,222,222), fg_alt, yellow, orange, blue=(82,179,203), green, red, purple, blue2=(71,120,186), yellow2, white, grey
- These match v1's exact palette values (lines 75-85 of v1/main.lua)

**Wall system port — Phase A (boundary + collision):**
- Created `map_generation.lua` with: `triangulate(verts)` (ear-clipping), `map_gen_jagged_h/v(verts, ..., step, jitter, jitter_along)`, `map_gen_corner(verts, cx, cy, start_angle, end_angle, r, jitter, steps)`
- Replaced v1's `rng:float()` with v2's `random_float()`
- `map_boundary = class()` entity wrapping a static chain collider, made via `make_entity`
- `map_gen_finalize(verts)` triangulates, builds chain collider with CCW local verts (for inward-facing normals)
- `generate_arena_rectangle()` adapted from v1's generate_linear_map: 480×270 with margin=20, jitter=6, step=20, corner_radius=30
- Added `wall_layer` separate from `game_layer`; bg fill on wall_layer; floor triangles on wall_layer

**Phase B step 1 — distance field visualization:**
- Created `wall.lua` with `compute_wall_distances(m)` ported from v1
- Bucketed by columns (bucket_size = scale*8) for performance; tens of ms not v1's seconds
- Initial params: fade_dist=30, margin=20, scale=4 — too tight, no visible gradient
- Visualized as grayscale `df_texture` via `texture_create(tw, th, table.concat(pixels))`
- **Engine bug discovery #1:** v2's `layer_draw_texture` is the raw C function expecting layer pointer, not state table; correct wrapper is `layer_texture(lyr, tex, x, y)`. Crash without error.
- **Camera follow added:** created `main_camera = camera_new(width, height)`, `camera_follow(main_camera, p)`, `camera_update`, `camera_attach`/`camera_detach` for wall and game layers; bg drawn screen-fixed (no camera attach)
- After camera: tuned to fade_dist=80, margin=250 to see proper gradient extent
- User: increased fade_dist to 120 (1.5x bigger transition)

**Phase B step 2 — colored gradient bake:**
- Added `bake_wall_gradient(m)` — interpolates `mix(wall_color, wall_color_2, distance)` per texel into RGBA texture
- Wall colors: `wall_color = color_darken(blue, 0.4)`, `wall_color_2 = color_darken(blue2, 0.3)`, matching v1 blue palette
- Floor color: `floor_color = color_darken(blue, 0.18)` placeholder
- Drawing order: bg → gradient texture → floor triangles → (later) edge → (later) symbols
- Confirmed match with v1 visual

**Phase C — edge lines:**
- `draw_wall_edge(m, layer)` iterates m.floor.vertices, draws line segments between consecutive verts
- `wall_edge_color = color_darken(blue, 0.6)` matches v1's `p.wall * 0.6` formula exactly
- `wall_edge_width = 2`

**Phase D — symbol scattering + per-pixel coloring:**
- **Simplification proposed:** v1 uses one big shader with marker-color (255,254,253) trick to detect symbol pixels on a combined layer. v2 uses a separate symbol_layer with a small dedicated shader.
- Initially: `scatter_wall_symbols(m)` with jittered grid, per-symbol color computed at scatter time
- User asked for Poisson disc instead — replaced with v1's `poisson_disc(x0, y0, x1, y1, r, k)` (Bridson's algorithm), `dist_poisson` wrapper
- `wall_symbol_size=6`, `wall_symbol_width=3`, `wall_symbol_darken=0.175`, spacing = symbol_size*6 = 36
- `point_to_polygon_edge_dist`, `point_in_polygon` helpers (ray-casting)
- Symbols filtered: must be > margin from polygon edge AND outside polygon
- Each X drawn as two crossing diagonal lines, random rotation 0 to π/2

**Per-pixel symbol coloring:**
- User noticed symbols were single-color (per-symbol, not per-pixel like v1)
- Created `assets/wall_symbols.frag` (~30 lines): samples u_dist_field at fragment's world position, outputs `mix(u_color_near, u_color_far, dist) * (1 - u_darken)` with original alpha
- World position recovered from `TexCoord + u_cam + u_screen` (matches v1's wall_gradient.frag formula)
- Applied as post-process to symbol_layer via `layer_apply_shader`
- Uniforms set per frame in `apply_wall_symbols_shader(m, layer)`: u_cam, u_screen, u_df_origin, u_df_size, u_color_near/far (vec4 normalized), u_darken (float), u_dist_field (texture, unit 1)
- Removed `recompute_wall_symbol_colors` (no longer needed)

**Map class refactor (major architectural change):**
- User proposed map class to own all map-specific state (palette, generation, entities, textures)
- Discussed tradeoffs: (a) my original plain-table+globals vs (b) user's map instance
- Conclusion: instance approach better — explicit state ownership, centralized cleanup, future-proof for portal previews etc.
- Used `class()` syntax matching v2's pattern (player, collider) with `:new`, `:update`, `:draw`, `:destroy`, `:add_entity` methods
- Player NOT map-owned — persists across map swaps; load_map repositions via `p.collider:set_position(spawn_x, spawn_y) + set_velocity(0, 0)`
- Created `map.lua`: `map = class()`, `maps = {}` registry, `current_map` global, `load_map(name)` function
- Created `maps/hideout.lua`: hideout's def table with all visual params + spawn + `generate(m)` callback
- Refactored `wall.lua` functions to take `m` first arg: `compute_wall_distances(m)`, `bake_wall_gradient(m)`, `scatter_wall_symbols(m)`, `draw_wall_*(m, layer)`, `apply_wall_symbols_shader(m, layer)` — state on `m.gradient_cache`, `m.wall_points`, `m.floor` instead of globals
- Refactored `map_generation.lua`: `map_gen_finalize(m, verts)`, `generate_arena_rectangle(m)`
- main.lua simplified: only SNKRX palette globals + wiring; wall draws delegated to `current_map:draw(wall_layer, symbol_layer)`
- map:destroy frees both gradient textures via `texture_unload` + kills all entity_ids; map_boundary added to entity manifest so destruction cascades

**F5 reload + texture leak fix:**
- Added `bind('reload_map', 'key:f5')`; in update: `if is_pressed('reload_map') then load_map('hideout') end`
- Added `process_destroy_queue()` call inside load_map after destroy and before creating new map — ensures map-owned colliders are destroyed before new ones enter physics world (otherwise old + new coexist for a frame)
- **Engine bug discovery #2:** F5 crashed without error. Root cause: `texture_unload` called `free(tex)` on Lua-managed userdata memory.
  - `texture_load` returns light userdata pointing to malloc'd Texture (registered for shutdown cleanup)
  - `texture_create` returned full userdata (Lua-managed memory containing copied Texture struct), original heap freed
  - `texture_unload` assumed malloc'd model — `free()` on Lua memory = crash
  - **Fix in `Anchor/engine/src/anchor.c` l_texture_create:** changed to return light userdata pointing to malloc'd Texture, registered like texture_load. Both now have same shape, texture_unload works uniformly.
  - Rebuilt engine via `cd E:/a327ex/Anchor/engine && ./build.bat`, copied to `E:/a327ex/Orblike/anchor.exe`
- F5 now cleanly reloads — fresh polygon, fresh symbols, properly freed textures

**plan.md updates:**
- Removed ESC stub bullet from Phase 1 (will happen in Phase 2 with real UI primitives)
- Added "Before Phase 2 — Memory tracking" section: track GL resource counts (textures, FBOs, shaders) + native heap (Box2D bodies, audio, fonts) + Lua heap via `collectgarbage("count")`; F3 toggle overlay; validate F5 keeps counters flat

**Flat wall layout prototype (later reverted):**
- User: "Let's just do a mix of straight walls with more rocky looking portions" — every side has both flat walls and rocky portions
- Implementation: `emit_side(verts, walls, x1, y1, x2, y2, opts)` walks an axis-aligned side, alternating between rocky (jagged) and flat (straight) segments
- `generate_hideout(m)` in maps/hideout.lua: rejection-sampled placement of 3-5 walls across 4 sides, each 40-100 px (later 80-160), with min_gap=30 (later 80) between walls on same side and corner_buffer=20 (later 30) from corners
- Console prints "Hideout: N walls placed (T/R/B/L per side)"
- Iteration 1: tapered jitter near walls (jitter_low=6, jitter_high=14, jitter_decay=40) to make rocks wilder near walls — user rejected this approach
- Iteration 2: per user sketch, walls inset from baseline + tapered "bump" on one side rising further inward
  - `wall_inset = 20` (walls pushed inward from baseline)
  - `bump_peak = 30` (extra inward at peak)
  - `bump_peak_pos = 30` (distance from wall where peak hits)
  - `bump_length = 100` (taper completes at this distance)
  - Each wall: random `bump_dir` of -1 (bump before) or +1 (bump after); always exactly one side bumped
  - Inward direction = side direction rotated 90° CCW
  - Bump shape: linear-up from wall_inset at d=0 to peak at bump_peak_pos, linear-down from peak to 0 at bump_length
- User: "Hmmmm, this isn't it. Revert all changes back to normal." — reverted both files to pre-walls state
- maps/hideout.lua now calls `generate_arena_rectangle(m)` again; `emit_side` removed from map_generation.lua

**State at session end:**
- Hideout uses v1 arena rectangle (all-rocky perimeter)
