Use this skill for collision, physics bodies, movement, and spatial queries in melonJS — the built-in SAT world and the planck, matter and Rapier adapters. Covers bodyDef vs Body, collision types and masks, the collision callback family and their firing rules, raycast/queryAABB/querySphere, the behaviour differences between adapters, and which one to pick for a given game. Triggers on: which physics engine, choosing an adapter, switching adapters, setAdapter, PhysicsAdapterClass, create, rotati…

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'melonjs-physics' ] || [ -L ~/.agents/skills/'melonjs-physics' ]; then echo 'A skill folder named melonjs-physics already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melonjs/melonJS' "$d" && git -C "$d" checkout --quiet 'ea6157308367fab7a5aa7ba6ee719b4a1f79fae8' -- 'packages/melonjs/skills/melonjs-physics' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/melonjs/skills/melonjs-physics' ~/.agents/skills/'melonjs-physics' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'melonjs-physics' ~/.claude/skills/'melonjs-physics' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
