# roblox-animation

A skill for Roblox character animation: tracks, IK poses, marker events and UI tweens. Useful when you need locomotion or an emote without breaking priorities.

## What it does

The skill picks a motion system for the job. Authored rig motion goes through `Animator` and `AnimationTrack`, with priority, weight, fade and speed. Simple property changes and UI transitions go through `TweenService`. Procedural poses — a hand reaching for an object, a foot landing on uneven ground — go through `IKControl`.

Three references ship with it: `references/3d-animations.md` covers loading and blending tracks, `references/ui-tweens-and-sequences.md` covers properties, easing and typewriter text, `references/integration-and-events.md` covers wiring markers into gameplay. There are also three starter scripts: `AnimationLoader.lua`, `TweenHelper.lua`, `IKSetup.lua`. A marker in a track can fire a footstep sound, a particle, a hitbox or a cooldown-ring tween.

The trap is trusting client markers. For NPCs and other characters the server is the authority, so damage windows need server-side validation — otherwise a hit lands on the picture alone. The skill also flags `Humanoid:LoadAnimation` as deprecated and warns against tweening raw pixel offsets instead of scale plus `AnchorPoint`, because that breaks the moment resolution changes.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nonlooped/roblox-suite roblox-animation
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/nonlooped/roblox-suite --path roblox-animation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-animation -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/nonlooped/roblox-suite/tree/HEAD/roblox-animation/SKILL.md

## When to use it
- blend idle, walk and attack tracks into one locomotion set
- fire a footstep sound and particles from a track marker
- set up an IK pose for a hand or foot against the environment
- fade a UI panel in with a tween
- fix an animation that plays without fade or never cleans up

## Example prompts
- Build a walk animation for a Roblox character: idle on low priority, walk on medium, attack on high with a fade.
- Add a Footstep marker to the track and hook a sound plus a particle to the foot Attachment.
- Set up IKControl so the character's hand reaches the target, and check the elbow limits.

# roblox-animation

Choose animation tracks for authored rig motion, TweenService for property changes, and IKControl for procedural poses. Validate gameplay outcomes on the server even when a client animation triggers the visual effect.

**Key official sources:**
- https://create.roblox.com/docs/animation (overview)
- https://create.roblox.com/docs/animation/editor
- https://create.roblox.com/docs/animation/inverse-kinematics
- https://create.roblox.com/docs/animation/events
- https://create.roblox.com/docs/ui/animation (UI tweens + typewriter)
- Engine: Animator, AnimationTrack, Animation, AnimationClipProvider, IKControl, TweenService, TweenInfo, Tween, Enum.AnimationPriority, Enum.EasingStyle, etc.
- Full reference: https://create.roblox.com/docs/reference/engine

Cross-skill usage:
- Combine with roblox-user-interfaces for UI motion details and "particles in UI".
- Combine with roblox-vfx when animations should trigger emitters, beams, or trails via markers.
- Combine with roblox-core for Animator acquisition, RunService timing, and preloading via ContentProvider.
- Use roblox-networking to decide where to play/ control animations (server replication vs client-only cosmetics).

## Choose a motion system

**3D rig/character motion that needs to look authored and blendable?**  
→ Animation system (Animator + AnimationTrack). Pre-authored in Editor or from catalog, played with priority/weight/fade/speed. Drive gameplay from markers.

**Simple property changes, UI transitions, or one-off object motion?**  
→ TweenService. Use for GuiObjects (scale + AnchorPoint + UDim2), CFrame, Color3, Transparency, NumberSequence, etc.

**Need procedural interaction with environment (hand reaching, head tracking, foot placement on uneven ground)?**  
→ IKControl (procedural) + optional AnimationTracks or constraints for limits. Often combined with animation events.

**Combining systems:** Play a locomotion track on low priority while using IKControl or tweens for upper-body or UI overlays. Use markers in the track to start/stop IK or fire tweens/effects.

See references/3d-animations.md and references/ui-tweens-and-sequences.md for details.
