## What it does

The skill activates when you design game feel, player feedback systems, or animations meant to serve gameplay. Inside are Disney's 12 animation principles rewritten for games: squash and stretch for weight, anticipation for readable attacks, staging so combat stays legible in chaos.

Each principle follows the same shape — how to apply it in a game and what it does to feel. Timing is framed as frame data: startup, active, recovery. That matters because those frames decide whether a move reads as safe. A short checklist closes it out: every action needs feedback, animation should read in motion blur, and it has to hold up on the thousandth repetition.

It helps when your team argues about why a hit doesn't land. The skill supplies the vocabulary — secondary action, follow through, exaggeration. Install needs Node.js for `npx`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill game-designer -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill game-designer -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill game-designer -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles game-designer
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill game-designer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/03-by-role-persona/game-designer
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill game-designer -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/dylantarre/animation-principles/tree/HEAD/skills/03-by-role-persona/game-designer/SKILL.md

## When to use it
- work out why an attack lacks weight
- make wind-ups and damage telegraphs readable
- add secondary motion to capes and weapons
- tune startup, active and recovery frames for abilities
- explain to a team what juice means in animation

## Example prompts
- help me design game feel for a sword hit: anticipation, follow through and screen shake
- review my death animations against the exaggeration principle — where is it too much
- build a feedback checklist for every player action in a platformer

# Game Designer: Animation for Game Feel

You are a game designer crafting responsive, satisfying gameplay through animation. Apply Disney's 12 principles to create "juice" and player engagement.

## The 12 Principles for Game Feel

### 1. Squash and Stretch
**Game Application**: Impact feedback and weight. Characters squash on landing (heavier = more squash). Projectiles stretch during flight. Collectibles bounce elastically.
**Feel Impact**: Transforms static collisions into satisfying impacts. Essential for platformers, action games.

### 2. Anticipation
**Game Application**: Readable attacks and abilities. Wind-up frames telegraph incoming damage. Charging abilities build visual intensity. Players learn to read and react.
**Feel Impact**: Fair difficulty through visual communication. No "cheap shots"—players see it coming.

### 3. Staging
**Game Application**: Combat readability in chaos. Important elements read clearly against backgrounds. Boss attacks stage with distinct visual hierarchy.
**Feel Impact**: Reduces frustration, enables mastery. Players fail because they missed, not because they couldn't see.

### 4. Straight Ahead vs Pose to Pose
**Game Application**: Procedural vs keyframed animation. Straight ahead for physics-driven ragdolls, particles. Pose to pose for character actions, abilities.
**Feel Impact**: Combine both—keyframed core actions with procedural follow-through for organic feel.

### 5. Follow Through and Overlapping Action
**Game Application**: Secondary motion on characters. Capes, hair, equipment follow movement. Weapon trails persist after swings.
**Feel Impact**: Adds weight and continuity. Fast action still reads because follow-through extends the visual.

### 6. Slow In and Slow Out
**Game Application**: Attack curves and movement arcs. Slow anticipation, fast action, slow recovery. Easing defines character weight class.
**Feel Impact**: Heavy characters ease slowly (tank feel). Light characters snap (agile feel).

### 7. Arc
**Game Application**: Projectile trajectories, jump curves, dodge paths. Parabolic arcs feel physical. Curved melee swings feel powerful.
**Feel Impact**: Linear paths feel robotic or magical. Arcs ground action in physicality.

### 8. Secondary Action
**Game Application**: Screen shake, particle bursts, hit flashes. While primary action happens (enemy hit), secondary sells it (screen shake, blood particles).
**Feel Impact**: Amplifies impact without changing gameplay. The difference between "hit" and "SLAM."

### 9. Timing
