roblox-physics SKILL.md skillA
roblox-physics from gamedev-skills/awesome-gamedev-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Implement Roblox physical simulation and queries with assemblies, anchoring, constraints, collision groups, CanCollide/CanTouch/CanQuery, raycasts and overlap queries, mass, impulses, forces, velocity, moving assemblies, cleanup, and network ownership. Use for Roblox collisions, hit detection, RaycastParams, PhysicsService, projectiles, vehicles, knockback, constraints, deprecated BodyMovers, unstable motion, or client-owned physics exploits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Roblox physics Choose deliberately between simulation, character control, hit detection, and visual-only motion; they are different jobs. Targets Roblox's rolling platform APIs. Pair with `physics-tuning` for engine-neutral stability and feel. ## When to use - Use for BasePart assemblies, constraints, collision/query policy, ray/overlap queries, forces, impulses, moving physical objects, network ownership, or physics cleanup. - Use when `Touched` is unreliable/security-sensitive, parts tunnel or jitter, a mechanism breaks when anchored, or old BodyMover patterns appear. **When not to use:** ordinary Humanoid lifecycle/control belongs to `roblox-characters`; remote validation belongs to `roblox-networking`; decorative UI/world motion may only need a tween. ## Decide the system first | Goal | Mechanism | |---|---| | sustained physical interaction | unanchored assembly + modern constraints/forces | | instantaneous physical change | `ApplyImpulse` / `ApplyAngularImpulse` | | kinematic platform/path | controlled pivot/transform with an explicit passenger policy | | character locomotion | Humanoid/custom character controller (`roblox-characters`) | …

How to install
mdr add gamedev-skills/awesome-gamedev-agent-skills/roblox-physics@sha256:b91d88793183b61eThe line at the top of this page pins the label git:20260908.c17213a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
