ue-physics-collision

quodsoler/unrea…e-skills

Use when setting up collision channels and profiles, running line/sweep/overlap queries, wiring hit and overlap events, or simulating rigid bodies in Unreal Engine C++. Also use when the user mentions 'collision channel', 'collision profile', 'LineTraceSingleByChannel', 'SweepSingleByChannel', 'OverlapMultiByObjectType', 'FHitResult', 'FCollisionQueryParams', 'FCollisionShape', 'OnComponentHit', 'OnComponentBeginOverlap', 'SetCollisionProfileName', 'SetSimulatePhysics', 'AddRadialImpulse', 'ragdoll', 'Chaos solver', 'ECC_GameTraceChannel1', or 'my overlap never fires'. For component attachment, see ue-actor-component-architecture; for capsule floor checks, see ue-character-movement.

UE Physics & Collision

Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".

Collision and physics live in the Engine module (UPrimitiveComponent, UWorld queries, FHitResult, UCollisionProfile) and the PhysicsCore module (FCollisionShape, UPhysicalMaterial, FBodyInstanceCore, ECollisionTraceFlag, EPhysicalSurface). The simulator itself is Chaos (Chaos / ChaosSolverEngine modules); destruction adds GeometryCollectionEngine and FieldSystemEngine. Most gameplay code only needs "Engine" and "PhysicsCore" in Build.cs.

Context

Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.

Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.
