456→### 1.17 Camera Integration
   457→
   458→**Goal**: Camera shake and handcam for ambient motion.
   459→
   460→**Camera shake**: `camera\shake\trauma 0.1` on significant collisions.
   461→
   462→**Handcam**: `camera\shake\handcam true, 0.5, 0.3` for subtle ambient motion.
   463→
   464→### 1.18 Gun Weapon + Projectiles ✓
   465→
   466→**Goal**: Ranged weapon that fires projectiles.
   467→
   468→**Implemented**:
   469→
   470→**Projectile class**:
   471→- Box collider (15x8), gravity scale 0.5, restitution 0.75
   472→- Sensor shape for ball detection (passes through balls)
   473→- Bounces twice on walls, dies on third hit
   474→- Can be parried by weapons (treated like wall hit)
   475→- `owner_id` prevents hitting the ball that spawned it
   476→- Spring feedback and flash on spawn
   477→- Yellow hit particles with gravity on wall/weapon impact
   478→
   479→**Gun weapon**:
   480→- `weapon_type = 'gun'` with gun-specific visuals (image, offsets, y-flip)
   481→- `weapon_category = 'ranged'` - no contact damage, can't kill plants (only sway)
   482→- Auto-fires when raycast from gun tip detects enemy ball
   483→- 0.6s cooldown between shots using `timer\when` with manual `@gun_ready` flag
   484→- Recoil animation: rotation (-45°) + position offset (4px toward ball), tweens back
   485→- `boom_particle` muzzle flash effect (boom emoji scales down quickly)

Based on the search results, here's what I found about Freya Holmér's Shapes Unity plugin and gradient API documentation:

## Overview of Shapes

Shapes is a real-time vector graphics library for Unity by Freya Holmér.(no content)It offers high-quality line drawing and infinite resolution shapes, rendered with advanced anti-aliasing techniques.

## Gradient API Documentation

Users have noted that programmatically filling a Polygon with a linear gradient in ImmediateMode isn't immediately obvious in terms of what objects and settings need to be applied.(no content)According to Freya Holmér's response, the gradient documentation is "currently a little hidden away on the changelog page, under version 4.0.0" if you want a guide.

## Resources

- **Main Website**: https://acegikmo.com/shapes
- **Documentation**: https://acegikmo.com/shapes/docs/
- **Feedback Center**: shapes.userecho.com
- The asset is available on the Unity Asset Store for $100, currently at version 4.5.1 (updated April 30, 2025).

## Additional Notes

Freya added an interactive color picker sample scene for immediate mode drawing as of version 4.2.0. Some users have noted that the asset is based on a high level of mathematical knowledge and wished for more tutorials explaining the sample materials.

For detailed gradient API usage, I'd recommend checking the changelog page for version 4.0.0 on the official documentation site at acegikmo.com/shapes/docs/.

Here's what I found about Cairo graphics library's gradient fill shapes API for linear and radial gradients:

## Overview

There are three main kinds of sources in cairo: colors, gradients, and images.(no content)Gradients describe a progression of colors by setting a start and stop reference location and a series of "stops" along the way. Linear gradients are built from two points which pass through parallel lines to define the start and stop locations. Radial gradients are also built from two points, but each has an associated radius of the circle on which to define the start and stop locations.

## Linear Gradients

Linear gradients are blendings of colours or shades of colours along a line. They are created with the `cairo_pattern_create_linear` function.(no content)The `LinearGradient` accepts two points (x0, y0) and (x1, y1) that determine the extent of the gradient.

## Radial Gradients

Radial gradients are blendings of colours or shades of colours between two circles.(no content)Creates a new radial gradient `cairo_pattern_t` between the two circles defined by (cx0, cy0, radius0) and (cx1, cy1, radius1). Before using the gradient pattern, a number of color stops should be defined using `Cairo::Gradient::add_color_stop_rgb()` or `Cairo::Gradient::add_color_stop_rgba()`.

## Key API Functions

`cairo_pattern_add_color_stop_rgb()` adds an opaque color stop to a gradient pattern. The offset specifies the location along the gradient's control vector. For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle.(no content)`cairo_pattern_add_color_stop_rgba()` adds a translucent color stop to a gradient pattern. The offset specifies the location along the gradient's control vector.(no content)A notable exception is `cairo_pattern_add_color_stop_rgb()` and `cairo_pattern_add_color_stop_rgba()` which must only be called with gradient patterns (either LINEAR or RADIAL). Otherwise the pattern will be shutdown and put into an error state.

## Color Stops

Stops are added to the gradient with `cairo_add_color_stop_rgb()` and `cairo_add_color_stop_rgba()` which take a color like `cairo_set_source_rgb*()`, as well as an offset to indicate where it lies between the reference locations. The colors between adjacent stops are averaged over space to form a smooth blend. Finally, the behavior beyond the reference locations can be controlled with `cairo_set_extend()`.(no content)The four parameters (double) given to LinearGradient constructor specify a gradient vector (x0, y0, x1, y1). The first parameter given to AddColorStop is the offset (0 to 1). The point located at x0, y0 will have the color where offset = 0, while point located at x1,y1 will have a color of offset = 1. Other values are interpolated between the two. You can add as many color stops as you need.

## Retrieving Gradient Information

`cairo_pattern_get_radial_circles()` gets the gradient endpoint circles for a radial gradient, each specified as a center coordinate and a radius.(no content)`cairo_pattern_get_color_stop_rgba()` gets the color and offset information at the given index for a gradient pattern. Values of index range from 0 to n-1 where n is the number returned by `cairo_pattern_get_color_stop_count()`.

Here's what I found about the HTML5 Canvas gradient API:

## Overview

HTML5 Canvas gradients are patterns of color that can be used as the fill or stroke of shapes, instead of solid colors.(no content)Different shapes, such as rectangles, circles, lines, text, etc, can be filled with Gradients.(no content)There are two types of gradients: `createLinearGradient(x,y,x1,y1)` for creating a linear gradient, and `createRadialGradient(x,y,r,x1,y1,r1)` for creating a radial gradient.

## createLinearGradient()

The `CanvasRenderingContext2D.createLinearGradient()` method of the Canvas 2D API creates a gradient along the line connecting two given coordinates.(no content)The `createLinearGradient()` method is specified by four parameters defining the start and end points of the gradient line. Parameters include:

- The x-axis and y-axis coordinates of the start point
- The x-axis and y-axis coordinates of the end point(no content)A linear gradient changes color along a linear pattern (horizontally/vertically/diagonally).

## createRadialGradient()

The `CanvasRenderingContext2D.createRadialGradient()` method of the Canvas 2D API creates a radial gradient using the size and coordinates of two circles.(no content)The `createRadialGradient()` method is specified by six parameters, three defining the gradient's start circle, and three defining the end circle.(no content)A radial gradient is defined by 2 circles. Each circle has a center point and a radius.

## Applying Gradients to Shapes

To be applied to a shape, the gradient must first be assigned to the `fillStyle` or `strokeStyle` properties.(no content)Note: Gradient coordinates are global, i.e., relative to the current coordinate space. When applied to a shape, the coordinates are NOT relative to the shape's coordinates.

## Color Stops

The `addColorStop()` method specifies the color stops, and its position along the gradient. The positions can be anywhere between 0 and 1.(no content)You must add a color stop to a gradient object to make the gradient visible.

Here's what I found about conic gradients and the `createConicGradient` API:

## Canvas 2D API: `createConicGradient()`

The `CanvasRenderingContext2D.createConicGradient()` method of the Canvas 2D API creates a gradient around a point with given coordinates.(no content)This method returns a conic `CanvasGradient`. To be applied to a shape, the gradient must first be assigned to the `fillStyle` or `strokeStyle` properties.

### Syntax
The syntax is: `CanvasRenderingContext2D.createConicGradient(angle, x, y)`(no content)When using conic gradients, `CanvasGradient` stops are normalized from 0 to 1 (as opposed to using radians). This is consistent with other gradients that use normalized values.

### CanvasGradient Interface
The `CanvasGradient` interface represents an opaque object describing a gradient. It is returned by the methods `createLinearGradient()`, `createConicGradient()`, or `createRadialGradient()`. It can be used as a `fillStyle` or `strokeStyle`.

## What is a Conic Gradient?

The conic-gradient creates an image consisting of a gradient with color transitions rotated around a center point (rather than radiating from the center). Example conic gradients include pie charts and color wheels.(no content)Conic gradients create color transitions that sweep around a center point, similar to a color wheel or pie chart. Unlike radial gradients that radiate outward, conic gradients rotate around a point, making them perfect for creating color wheels, pie charts, and unique background effects.(no content)CSS conic-gradient is a powerful function that creates gradients that sweep around a center point, forming angular patterns similar to pie charts or color wheels. Unlike linear or radial gradients, conic gradients rotate around a central axis.

### CSS Syntax
The CSS syntax is: `conic-gradient([from angle] [at position,] color [degree], color [degree], ...)`. By default, angle is 0deg and position is center. If no degree is specified, the colors will be spread equally around the center point.(no content)The conic-gradient syntax is similar to the radial-gradient syntax, but the color-stops are placed around a gradient arc, the circumference of a circle. With conic gradients, the colors transition as if spun around the center of a circle, starting at the top and going clockwise.

1→# Emoji Ball Battles - Implementation Plan
     2→
     3→## Philosophy
     4→
     5→This plan follows the **beginning/end/constraint** framework:
     6→
     7→1. **Beginning**: Get the moment-to-moment combat working
     8→2. **End**: Validate power fantasies by implementing actual classes/weapons/items and testing broken builds
     9→3. **Middle**: Only then build the meta loop (draft, evolution, etc.) — planned after Phase 2 findings
    10→
    11→---
    12→
    13→## Architecture Principles
    14→
    15→### Single File
    16→
    17→The entire codebase lives in `main.yue`. No separate modules, no `game/` or `data/` folders.

   102→Balls are children of arena, allowing arena to manage fight state and collision systems.
   103→
   104→---
   105→
   106→## Phase 1: Beginning (Basic Combat)
   107→
   108→### 1.1 Arena Setup ✓
   109→
   110→**Goal**: Walled rectangular arena with gravity.
   111→
   112→**Wall design**: Walls are huge blocks that extend well beyond screen boundaries. This ensures screen shake never reveals edges.
   113→
   114→**Implemented**:
   115→- Screen size: 480x270 at 3x scale (1440x810 window)
   116→- Play area: 200x200, centered (scaled from 600x600 at 1920x1080)
   117→- Wall thickness: 200 pixels (extends off-screen)
   118→- Walls are static box colliders with `wall` physics tag
   119→- Gravity: `an\physics_set_gravity 0, 384`
   120→- `arena` class contains walls as children
   121→- `wall` class: static box collider, draws itself in `update`
   122→- Wall color: `fg\clone!\mix yellow, 0.1` (slightly yellowed background)
   123→
   124→### 1.2 Ball with Physics ✓
   125→
   126→**Goal**: Two balls that bounce around the arena.
   127→
   128→**Implemented**:
   129→- Ball is an object with circle collider (dynamic body), radius 10
... [120 more lines]

250→- Physics world step uses scaled dt
   251→
   252→**Framework binding** (init.yue):
   253→- `an.time_scale` — synced to engine each frame
   254→- `an.dt` — scaled delta time
   255→- `an.unscaled_dt` — unscaled delta time
   256→
   257→### 1.7 Spritesheet Support ✓
   258→
   259→**Goal**: Load spritesheets and draw specific frames for animations.
   260→
   261→**Implemented** (anchor.c):
   262→- `spritesheet_load(path, frame_width, frame_height, padding)` — loads spritesheet
   263→- `spritesheet_get_frame_width/height/total_frames` — getters
   264→- `layer_draw_spritesheet_frame(layer, spritesheet, frame, x, y, color, flash)` — draws frame
   265→
   266→**Framework binding**:
   267→- `an\spritesheet(name, path, frame_width, frame_height, padding?)` — registers spritesheet
   268→- `an.spritesheets[name]` — access registered spritesheet
   269→- Spritesheet has `.frames`, `.frame_width`, `.frame_height` properties
   270→- `layer\spritesheet(sheet, frame, x, y, color, flash)` — draws frame (use push/pop for transforms)
   271→
   272→### 1.8 Slow-Mo System ✓
   273→
   274→**Goal**: Easy slow-motion triggers with automatic recovery.
   275→
   276→**Implemented** (init.yue):
   277→```yue
   278→an\slow(amount, duration=0, easing=math.cubic_in_out, tag='slow')
   279→an\cancel_slow(tag='slow')
... [120 more lines]

400→**Implemented**:
   401→
   402→**Plant class** (`plant` in main.yue):
   403→- Ghost sensor collider for detecting ball/weapon passing through
   404→- Per-plant properties: image, size (w/h), layer (front/back for depth), y offset, min_rotation
   405→
   406→**Group-based spawning system**:
   407→- 8 predefined plant group templates, each with specific plant compositions
   408→- Each group has defined horizontal extents (left/right bounds relative to spawn point)
   409→- Groups include: small seedling pairs, sheaf clusters, tulip rows, mixed arrangements with blossom/clover
   410→- Plants within groups use front/back layers for depth variation
   411→- 2-3 groups spawned per arena, randomly selected without replacement
   412→
   413→**Non-overlapping placement algorithm**:
   414→1. First group placed randomly within safe horizontal range
   415→2. Subsequent groups attempt random placement, checking overlap with all previously placed groups
   416→3. If random attempts fail after 50 tries, finds gaps between placed groups
   417→4. Places in largest gap that fits the group (with 10px margin)
   418→5. Groups track their occupied horizontal extent for collision checking
   419→
   420→**Two force types**:
   421→
   422→1. **Moving force** (gentle sway from passing objects):
   423→   - Triggered by weapon passing through plant's ghost sensor
   424→   - Weapon velocity calculated from angular velocity: `weapon_vx = -av * offset * sin(angle)`
   425→   - Uses damped velocity physics for smooth return to rest
   426→   - `@moving_max_v` controls maximum rotation velocity
   427→
   428→2. **Direct force** (snappy reaction to ground impacts):
   429→   - Triggered when ball collides with floor (normal_y > 0.5)

   211→

   213→    This system compensates by adding energy on collisions while creating interesting

   215→
   216→    1. ENERGY REDISTRIBUTION (keeps both balls active) - ball-ball collisions
   217→       Problem: When a fast ball hits a slow ball, energy transfers completely,
   218→       creating a "ping-pong" effect where only one ball is fast at a time.
   219→       Solution: At higher speeds, redistribute energy between balls favoring equal splits.
   220→       - Chance to redistribute increases with speed (0% at rest, 100% at max speed)
   221→       - Uses normal distribution centered at 0.5 for the split ratio
   222→       - Stddev shrinks at higher speeds (0.3→0.1), making equal splits more likely
   223→       - Apply @ball_energy_boost (1.09x) to compensate for Box2D energy leakage
   224→
   225→    2. HIGH SPEED BYPASS (creates pacing/rhythm) - ball-ball collisions
   226→       Problem: Constant high-speed action becomes monotonous and hard to follow.
   227→       Solution: Track consecutive high-speed hits. As count increases, probability of
   228→       bypassing grows (S-curve, guaranteed at 9 hits). When bypass triggers, balls
   229→       lose 30% energy, creating calm moments. Counter resets after bypass.

288→    COLLISION ENERGY SYSTEM
   289→
   290→    Box2D leaks energy even with restitution=1, causing balls to eventually stop bouncing.
   291→    This system compensates by adding energy on collisions while creating interesting
   292→    gameplay dynamics through energy redistribution and pacing control.
   293→
   294→    1. ENERGY REDISTRIBUTION (keeps both balls active) - ball-ball collisions
   295→       Problem: When a fast ball hits a slow ball, energy transfers completely,
   296→       creating a "ping-pong" effect where only one ball is fast at a time.
   297→       Solution: At higher speeds, redistribute energy between balls favoring equal splits.
   298→       - Chance to redistribute increases with speed (0% at rest, 100% at max speed)
   299→       - Uses normal distribution centered at 0.5 for the split ratio
   300→       - Stddev shrinks at higher speeds (0.3→0.1), making equal splits more likely
   301→       - Apply @ball_energy_boost (1.09x) to compensate for Box2D energy leakage
   302→
   303→    2. HIGH SPEED BYPASS (creates pacing/rhythm) - ball-ball collisions
   304→       Problem: Constant high-speed action becomes monotonous and hard to follow.
   305→       Solution: Track consecutive high-speed hits. As count increases, probability of
   306→       bypassing grows (S-curve, guaranteed at 9 hits). When bypass triggers, balls
   307→       lose 30% energy, creating calm moments. Counter resets after bypass.

330→       Problem: Weapon collisions drain energy from the system.
   331→       Solution: Apply @weapon_energy_boost (1.14x) on weapon-weapon collisions.
   332→       Also cap linear speed at @max_ball_speed and angular velocity at ball.max_angular_velocity.
   333→
   334→    Speed is capped at @max_ball_speed to prevent things from getting too chaotic.

1→# Emoji Ball Battles - Implementation Plan
     2→
     3→## Philosophy
     4→
     5→This plan follows the **beginning/end/constraint** framework:
     6→
     7→1. **Beginning**: Get the moment-to-moment combat working
     8→2. **End**: Validate power fantasies by implementing actual classes/weapons/items and testing broken builds
     9→3. **Middle**: Only then build the meta loop (draft, evolution, etc.) — planned after Phase 2 findings
    10→
    11→---
    12→
    13→## Architecture Principles
    14→
    15→### Single File
    16→
    17→The entire codebase lives in `main.yue`. No separate modules, no `game/` or `data/` folders.
