## What it does

The skill loads when you add or fix visual effects in Roblox: character animation, `ParticleEmitter`, beams, trails, tweens, camera shake. It also covers the annoying cases — an effect that stays invisible, feels too weak, lags, or never cleans up, and an animation that won't play or blend.

Inside is a quick reference to the engine pieces that matter. Tracks load through an `Animator` on a `Humanoid` or `AnimationController`, and `AnimationTrack.Priority` gets set on purpose. Named gameplay cues go through `GetMarkerReachedSignal()`, with the listener disconnected or replaced when the track ends. A burst `ParticleEmitter` usually runs with `Rate = 0` and fires `:Emit(count)`; frequent effects get pooled. Beams and trails need two attachments with a stable world-space relationship and an owner that removes them.

There is a separate section for Server Authority projects. Synchronized animation logic belongs in `RunService:BindToSimulation()`, which requires `Workspace.UseFixedSimulation` enabled in Studio. Current tracks are queried instead of cached across rollback, and predicted effects are made reversible. Profiling particle counts, lights and per-frame camera work should happen on the target device class. For recipes, the skill points to `references/full.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-animation-vfx -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-animation-vfx -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-animation-vfx -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TabooHarmony/roblox-brain roblox-animation-vfx
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-animation-vfx -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TabooHarmony/roblox-brain --path skills/gameplay/roblox-animation-vfx
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-animation-vfx -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/TabooHarmony/roblox-brain/tree/HEAD/skills/gameplay/roblox-animation-vfx/SKILL.md

## When to use it
- shape a hit effect into readable phases: warning, contact, peak, fade
- fix an animation that won't play or blend
- stop effects from leaking when they never clean up
- set up a burst `ParticleEmitter` with `:Emit(count)` instead of a constant stream
- move animation logic into `RunService:BindToSimulation()` for Server Authority

## Example prompts
- add a sword hit effect with particles, camera shake and a fade
- the run animation doesn't blend on transition — dig into it
- make the predicted effect reversible in a Server Authority project

# roblox animation and vfx

## When to Load

Load when implementing character animation, particle or beam effects, tweens, camera feedback, or visual cleanup.

## Quick Reference

- Load tracks through an `Animator` on a `Humanoid` or `AnimationController`; set `AnimationTrack.Priority` deliberately.
- Use `GetMarkerReachedSignal()` for named gameplay or presentation cues, then disconnect or replace the listener when the track ends.
- Track lifecycle: `Ended` is post-fade cleanup; `Stopped` includes explicit stops. Same-priority tracks blend by weight; see full.md for control and loading guards.
- A burst `ParticleEmitter` usually has `Rate = 0` and uses `:Emit(count)` with a bounded lifetime; use pooling for frequent effects.
- Shape each effect as readable phases: warning, contact, brief peak, and fade. Give impact a clear silhouette before adding secondary particles, light, sound, or camera feedback.
