# create-game-vfx

A skill that steers an AI agent through building Three.js visual effects: attacks, impacts, status effects, telegraphs. Useful when an effect has to read in combat and hold the frame rate.

## What it does

The skill sets an order of work: gameplay meaning first, spectacle after. For every effect the agent is told to pin down a trigger, owner, duration, gameplay meaning, silhouette at camera distance, colour hierarchy, spawn cap, cleanup rule and a reduced-motion equivalent. Telegraph, contact, success, failure and lingering status visuals stay separate.

On the implementation side it asks for pooled short-lived objects, reused materials and geometry, capped particles and no per-frame allocation. Additive blending and transparency go in sparingly near important UI and targets. Cleanup has to be idempotent, otherwise reset, death and pause leak effects.

Verification covers overlaps, several targets at once, rapid repetition, pause and resume, the lowest quality tier, reduced motion and touch viewports. The skill advises sampling the live encounter for warnings, draw calls, frame time and readability. Worth installing if your project already runs on Three.js — on another renderer the material and pooling steps need rewriting.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill create-game-vfx -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/create-game-vfx/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/create-game-vfx/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill create-game-vfx -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/create-game-vfx/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill create-game-vfx -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/create-game-vfx/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills create-game-vfx
```

2. **Manually: put the files in place**
- File: `.github/skills/create-game-vfx/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill create-game-vfx -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/game-development/create-game-vfx
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/create-game-vfx/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill create-game-vfx -a opencode
```

### Claude.ai

## When to use it
- separate the attack telegraph from the contact frame
- keep an effect readable from a distant camera
- cap particles without dropping frames in combat
- make effect cleanup safe across pause and reset
- ship a reduced-motion variant of an effect

## Example prompts
- build a Three.js hit VFX with pooled objects and a particle cap
- check the status effects for overlaps and rapid repetition, report frame time
- add an attack telegraph plus a separate reduced-motion variant

# Create Game VFX

Make the gameplay meaning visible before adding spectacle.

## Specify

For every effect define trigger, owner, duration, gameplay meaning, camera-distance silhouette, color hierarchy, spawn cap, cleanup rule, and reduced-motion equivalent. Separate telegraph, contact, success, failure, and lingering status visuals.

## Implement safely

Pool short-lived objects, reuse materials/geometry, cap particles, and avoid per-frame allocation. Use additive/transparency sparingly around important UI and targets. Make cleanup idempotent so reset, death, and pause cannot leak effects.

## Verify

Test overlaps, multiple targets, rapid repetition, pause/resume, lowest quality, reduced motion, and touch viewports. Sample the live encounter for warnings, draw calls, frame time, and visual readability.
```
