roblox-physics

separate

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.

When to use

• Use for BasePart assemblies, constraints, collision/query policy, ray/overlap queries, forces,
• Use when `Touched` is unreliable/security-sensitive, parts tunnel or jitter, a mechanism breaks

When not to use

• ordinary Humanoid lifecycle/control
• remote validation
• decorative UI/world motion
