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.

Collision Channels and Profiles

ECollisionChannel (Engine/EngineTypes.h:1098) has 8 engine channels, 6 hidden engine slots and 50 game slots (64 total; ECC_GameTraceChannel50 at :1168):

ECC_WorldStatic, ECC_WorldDynamic, ECC_Pawn, ECC_PhysicsBody,
ECC_Vehicle, ECC_Destructible                 // object channels (what a component IS)
ECC_Visibility, ECC_Camera                    // trace channels (what a query LOOKS FOR)
ECC_GameTraceChannel1 ... ECC_GameTraceChannel50  // project slots, either kind

Object channel — every component has exactly one, set with SetCollisionObjectType. Matched by *ByObjectType queries.
Trace channel — never an object type; a query passes it to *ByChannel and each component's response to that channel decides block/overlap/ignore.
ECollisionResponse (Engine/EngineTypes.h:1346): ECR_Ignore, ECR_Overlap, ECR_Block.
ECollisionEnabled::Type (Engine/EngineTypes.h:1805): NoCollision, QueryOnly, PhysicsOnly, QueryAndPhysics, ProbeOnly, QueryAndProbe.

#include "Components/PrimitiveComponent.h"

MyMesh->SetCollisionProfileName(TEXT("BlockAllDynamic"));   // preferred: one call sets everything
MyMesh->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
MyMesh->SetCollisionObjectType(ECC_PhysicsBody);
MyMesh->SetCollisionResponseToAllChannels(ECR_Block);
MyMesh->SetCollisionResponseToChannel(ECC_Pawn, ECR_Overlap);
MyMesh->SetCollisionResponseToChannel(ECC_Camera, ECR_Ignore);

FCollisionResponseContainer Responses(ECR_Ignore);
Responses.SetResponse(ECC_Visibility, ECR_Block);
MyMesh->SetCollisionResponseToChannels(Responses);

SetCollisionProfileName overwrites every manual response, so apply the profile first and the per-channel overrides after.

Engine profiles shipped in Config/BaseEngine.ini under [/Script/Engine.CollisionProfile]: NoCollision, BlockAll, OverlapAll, BlockAllDynamic, OverlapAllDynamic, IgnoreOnlyPawn, OverlapOnlyPawn, Pawn, Spectator, CharacterMesh, PhysicsActor, Destructible, InvisibleWall, InvisibleWallDynamic, Trigger, Ragdoll, Vehicle, UI, WaterBodyCollision.

Custom channels and profiles are config-only — there is no runtime API to create one:

[/Script/Engine.CollisionProfile]
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,DefaultResponse=ECR_Block,bTraceType=True,bStaticObject=False,Name="Weapon")
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel2,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False,Name="Interactable")
+Profiles=(Name="MyInteractable",CollisionEnabled=QueryAndPhysics,ObjectTypeName="Interactable",CustomResponses=((Channel="Weapon",Response=ECR_Ignore),(Channel="Visibility",Response=ECR_Block)),HelpMessage="Interactable props")
+EditProfiles=(Name="Pawn",CustomResponses=((Channel="Weapon",Response=ECR_Block)))

bTraceType=True declares a trace channel, False an object channel. +Profiles= adds or replaces a whole profile; +EditProfiles= only patches responses on an existing one (Engine/CollisionProfile.h:160-190). UCollisionProfile::Get() reads the table and UCollisionProfile::LoadProfileConfig(bool bForceInit) (Engine/CollisionProfile.h:237) re-reads it after a config change.

See collision-channel-setup.md for full profile sets, the ini reference and a debugging checklist.

Trace Sweep and Overlap Queries

All world queries are const members of UWorld (Engine/World.h:2128-2441). Three families, each in Test / Single / Multi form:

Suffix	Selects by	Extra parameter
`ByChannel`	the querier's trace channel vs each component's response	`ECollisionChannel TraceChannel`, optional `FCollisionResponseParams`
`ByObjectType`	the target component's object channel	`const FCollisionObjectQueryParams&`
`ByProfile`	the channel and responses stored in a named profile	`FName ProfileName`

#include "Engine/World.h"
#include "Engine/HitResult.h"
#include "CollisionQueryParams.h"
#include "CollisionShape.h"

FCollisionQueryParams Params(TEXT("MyWeaponTrace"), /*bTraceComplex=*/false, GetOwner());
Params.bReturnPhysicalMaterial = true;   // fills Hit.PhysMaterial
Params.bReturnFaceIndex        = false;  // fills Hit.FaceIndex; expensive
Params.bIgnoreTouches          = true;   // discard ECR_Overlap results (bIgnoreBlocks is the inverse)
Params.bFindInitialOverlaps    = true;   // report shapes already overlapping at Start
Params.MobilityType            = EQueryMobilityType::Any;  // Any | Static | Dynamic
Params.AddIgnoredActor(GetOwner());
Params.AddIgnoredComponent(MyMesh.Get());   // .Get(): a TObjectPtr member is ambiguous (CollisionQueryParams.h:267-269)

FHitResult Hit;
GetWorld()->LineTraceSingleByChannel(Hit, Start, End, ECC_Visibility, Params);

TArray<FHitResult> Hits;
GetWorld()->LineTraceMultiByChannel(Hits, Start, End, ECC_GameTraceChannel1, Params);

FCollisionObjectQueryParams ObjParams(ECC_Pawn);
ObjParams.AddObjectTypesToQuery(ECC_PhysicsBody);
GetWorld()->LineTraceSingleByObjectType(Hit, Start, End, ObjParams, Params);

GetWorld()->LineTraceSingleByProfile(Hit, Start, End, TEXT("BlockAll"), Params);

const bool bAnythingThere = GetWorld()->LineTraceTestByChannel(Start, End, ECC_Visibility, Params);

TraceTag is the first constructor argument; it also drives the TraceTagAll / named-tag debug drawing in the console.

Sweeps take a rotation and an FCollisionShape (PhysicsCore/Public/CollisionShape.h:284-316):

const FCollisionShape Sphere  = FCollisionShape::MakeSphere(30.f);                  // radius
const FCollisionShape Box     = FCollisionShape::MakeBox(FVector(50.f, 30.f, 80.f));// half-extents
const FCollisionShape Capsule = FCollisionShape::MakeCapsule(34.f, 88.f);           // radius, half-height

GetWorld()->SweepSingleByChannel(Hit, Start, End, FQuat::Identity, ECC_Pawn, Capsule, Params);
GetWorld()->SweepMultiByChannel(Hits, Start, End, FQuat::Identity, ECC_Pawn, Sphere, Params);
GetWorld()->SweepSingleByObjectType(Hit, Start, End, FQuat::Identity, ObjParams, Box, Params);
GetWorld()->SweepSingleByProfile(Hit, Start, End, FQuat::Identity, TEXT("Pawn"), Capsule, Params);

GetCapsuleHalfHeight() includes the end radius; GetCapsuleAxisHalfLength() is the shaft only.

Overlaps are stationary shape tests returning FOverlapResult (Engine/OverlapResult.h:12):

#include "Engine/OverlapResult.h"

TArray<FOverlapResult> Overlaps;
GetWorld()->OverlapMultiByObjectType(Overlaps, Center, FQuat::Identity,
    FCollisionObjectQueryParams(ECC_Pawn), FCollisionShape::MakeSphere(500.f), Params);
GetWorld()->OverlapMultiByChannel(Overlaps, Center, FQuat::Identity, ECC_Pawn,
    FCollisionShape::MakeSphere(500.f), Params);

const bool bBlocked = GetWorld()->OverlapAnyTestByChannel(Center, FQuat::Identity,
    ECC_WorldStatic, FCollisionShape::MakeBox(FVector(40.f)), Params);

for (const FOverlapResult& Result : Overlaps)
{
    AActor* Actor = Result.GetActor();
    UPrimitiveComponent* Comp = Result.GetComponent();
}

OverlapAnyTestByChannel stops at the first block or touch; OverlapBlockingTestByChannel ignores touches. When the query is "what is my own component already touching", use UPrimitiveComponent::GetOverlappingActors or ComponentOverlapComponent instead of a world query.

Async traces queue this frame and are readable next frame (Engine/World.h:2522, WorldCollision.h:148):

#include "WorldCollision.h"

// EAsyncTraceType: Test | Single | Multi
FTraceHandle Handle = GetWorld()->AsyncLineTraceByChannel(
    EAsyncTraceType::Single, Start, End, ECC_Visibility, Params);

FTraceDatum Datum;
if (GetWorld()->QueryTraceData(Handle, Datum) && Datum.OutHits.Num() > 0)
{
    const FHitResult& First = Datum.OutHits[0];
}

Passing a FTraceDelegate* (DECLARE_DELEGATE_TwoParams(FTraceDelegate, const FTraceHandle&, FTraceDatum&)) instead calls you back when the batch completes.

See trace-patterns.md for hitscan, melee sweep, interaction, ground check, AoE, line-of-sight and async sensor patterns, plus the Blueprint-layer UKismetSystemLibrary wrappers and performance guidance.

FHitResult

Engine/HitResult.h. Actor is no longer a member — the actor is reached through an accessor.

Hit.bBlockingHit;        // :107  false for a touch-only result
Hit.bStartPenetrating;   // :116  query began already overlapping; PenetrationDepth :91
Hit.Time;                // :33   0..1 along Start->End;  Distance :37 in cm
Hit.Location;            // :45   where the swept shape's origin ended up
Hit.ImpactPoint;         // :53   surface contact point
Hit.Normal;              // :61   normal opposing movement at Location
Hit.ImpactNormal;        // :69   geometric surface normal at ImpactPoint
Hit.TraceStart;          // :76;  TraceEnd :83
Hit.Item;                // :99   instance index (ISM/HISM); ElementIndex :103 shape index
Hit.FaceIndex;           // :26   needs Params.bReturnFaceIn

# 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.

## Collision Channels and Profiles

`ECollisionChannel` (`Engine/EngineTypes.h:1098`) has 8 engine channels, 6 hidden engine slots and 50 game slots (64 total; `ECC_GameTraceChannel50` at `:1168`):

```cpp
ECC_WorldStatic, ECC_WorldDynamic, ECC_Pawn, ECC_PhysicsBody,
ECC_Vehicle, ECC_Destructible                 // object channels (what a component IS)
ECC_Visibility, ECC_Camera                    // trace channels (what a query LOOKS FOR)
ECC_GameTraceChannel1 ... ECC_GameTraceChannel50  // project slots, either kind
```

- **Object channel** — every component has exactly one, set with `SetCollisionObjectType`. Matched by `*ByObjectType` queries.
- **Trace channel** — never an object type; a query passes it to `*ByChannel` and each component's response to that channel decides block/overlap/ignore.
- `ECollisionResponse` (`Engine/EngineTypes.h:1346`): `ECR_Ignore`, `ECR_Overlap`, `ECR_Block`.
- `ECollisionEnabled::Type` (`Engine/EngineTypes.h:1805`): `NoCollision`, `QueryOnly`, `PhysicsOnly`, `QueryAndPhysics`, `ProbeOnly`, `QueryAndProbe`.

```cpp
#include "Components/PrimitiveComponent.h"

MyMesh->SetCollisionProfileName(TEXT("BlockAllDynamic"));   // preferred: one call sets everything
MyMesh->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
MyMesh->SetCollisionObjectType(ECC_PhysicsBody);
MyMesh->SetCollisionResponseToAllChannels(ECR_Block);
MyMesh->SetCollisionResponseToChannel(ECC_Pawn, ECR_Overlap);
MyMesh->SetCollisionResponseToChannel(ECC_Camera, ECR_Ignore);

FCollisionResponseContainer Responses(ECR_Ignore);
Responses.SetResponse(ECC_Visibility, ECR_Block);
MyMesh->SetCollisionResponseToChannels(Responses);
```

`SetCollisionProfileName` overwrites every manual response, so apply the profile first and the per-channel overrides after.

Engine profiles shipped in `Config/BaseEngine.ini` under `[/Script/Engine.CollisionProfile]`: `NoCollision`, `BlockAll`, `OverlapAll`, `BlockAllDynamic`, `OverlapAllDynamic`, `IgnoreOnlyPawn`, `OverlapOnlyPawn`, `Pawn`, `Spectator`, `CharacterMesh`, `PhysicsActor`, `Destructible`, `InvisibleWall`, `InvisibleWallDynamic`, `Trigger`, `Ragdoll`, `Vehicle`, `UI`, `WaterBodyCollision`.

Custom channels and profiles are config-only — there is no runtime API to create one:

```ini
[/Script/Engine.CollisionProfile]
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,DefaultResponse=ECR_Block,bTraceType=True,bStaticObject=False,Name="Weapon")
+DefaultChannelResponses=(Channel=ECC_GameTraceChannel2,DefaultResponse=ECR_Block,bTraceType=False,bStaticObject=False,Name="Interactable")
+Profiles=(Name="MyInteractable",CollisionEnabled=QueryAndPhysics,ObjectTypeName="Interactable",CustomResponses=((Channel="Weapon",Response=ECR_Ignore),(Channel="Visibility",Response=ECR_Block)),HelpMessage="Interactable props")
+EditProfiles=(Name="Pawn",CustomResponses=((Channel="Weapon",Response=ECR_Block)))
```

`bTraceType=True` declares a trace channel, `False` an object channel. `+Profiles=` adds or replaces a whole profile; `+EditProfiles=` only patches responses on an existing one (`Engine/CollisionProfile.h:160-190`). `UCollisionProfile::Get()` reads the table and `UCollisionProfile::LoadProfileConfig(bool bForceInit)` (`Engine/CollisionProfile.h:237`) re-reads it after a config change.

See [collision-channel-setup.md](references/collision-channel-setup.md) for full profile sets, the ini reference and a debugging checklist.

```cpp
#include "Engine/World.h"
#include "Engine/HitResult.h"
#include "CollisionQueryParams.h"
#include "CollisionShape.h"

FCollisionQueryParams Params(TEXT("MyWeaponTrace"), /*bTraceComplex=*/false, GetOwner());
Params.bReturnPhysicalMaterial = true;   // fills Hit.PhysMaterial
Params.bReturnFaceIndex        = false;  // fills Hit.FaceIndex; expensive

Params.AddIgnoredActor(GetOwner());
Params.AddIgnoredComponent(MyMesh.Get());   // .Get(): a TObjectPtr member is ambiguous (CollisionQueryParams.h:267-269)

FHitResult Hit;
GetWorld()->LineTraceSingleByChannel(Hit, Start, End, ECC_Visibility, Params);

TArray<FHitResult> Hits;
GetWorld()->LineTraceMultiByChannel(Hits, Start, End, ECC_GameTraceChannel1, Params);

FCollisionObjectQueryParams ObjParams(ECC_Pawn);
ObjParams.AddObjectTypesToQuery(ECC_PhysicsBody);
GetWorld()->LineTraceSingleByObjectType(Hit, Start, End, ObjParams, Params);

GetWorld()->LineTraceSingleByProfile(Hit, Start, End, TEXT("BlockAll"), Params);

```

`TraceTag` is the first constructor argument; it also drives the `TraceTagAll` / named-tag debug drawing in the console.

GetWorld()->SweepSingleByChannel(Hit, Start, End, FQuat::Identity, ECC_Pawn, Capsule, Params);
GetWorld()->SweepMultiByChannel(Hits, Start, End, FQuat::Identity, ECC_Pawn, Sphere, Params);
GetWorld()->SweepSingleByObjectType(Hit, Start, End, FQuat::Identity, ObjParams, Box, Params);
GetWorld()->SweepSingleByProfile(Hit, Start, End, FQuat::Identity, TEXT("Pawn"), Capsule, Params);
```

`GetCapsuleHalfHeight()` includes the end radius; `GetCapsuleAxisHalfLength()` is the shaft only.

Overlaps are stationary shape tests returning `FOverlapResult` (`Engine/OverlapResult.h:12`):

```cpp
#include "Engine/OverlapResult.h"

TArray<FOverlapResult> Overlaps;
GetWorld()->OverlapMultiByObjectType(Overlaps, Center, FQuat::Identity,
    FCollisionObjectQueryParams(ECC_Pawn), FCollisionShape::MakeSphere(500.f), Params);
GetWorld()->OverlapMultiByChannel(Overlaps, Center, FQuat::Identity, ECC_Pawn,
    FCollisionShape::MakeSphere(500.f), Params);

const bool bBlocked = GetWorld()->OverlapAnyTestByChannel(Center, FQuat::Identity,
    ECC_WorldStatic, FCollisionShape::MakeBox(FVector(40.f)), Params);

for (const FOverlapResult& Result : Overlaps)
{
    AActor* Actor = Result.GetActor();
    UPrimitiveComponent* Comp = Result.GetComponent();
}
```

`OverlapAnyTestByChannel` stops at the first block **or** touch; `OverlapBlockingTestByChannel` ignores touches. When the query is "what is my own component already touching", use `UPrimitiveComponent::GetOverlappingActors` or `ComponentOverlapComponent` instead of a world query.

Async traces queue this frame and are readable next frame (`Engine/World.h:2522`, `WorldCollision.h:148`):

    EAsyncTraceType::Single, Start, End, ECC_Visibility, Params);

FTraceDatum Datum;
if (GetWorld()->QueryTraceData(Handle, Datum) && Datum.OutHits.Num() > 0)
{
    const FHitResult& First = Datum.OutHits[0];
}
```

Passing a `FTraceDelegate*` (`DECLARE_DELEGATE_TwoParams(FTraceDelegate, const FTraceHandle&, FTraceDatum&)`) instead calls you back when the batch completes.

See [trace-patterns.md](references/trace-patterns.md) for hitscan, melee sweep, interaction, ground check, AoE, line-of-sight and async sensor patterns, plus the Blueprint-layer `UKismetSystemLibrary` wrappers and performance guidance.

## FHitResult

`Engine/HitResult.h`. `Actor` is no longer a member — the actor is reached through an accessor.

```cpp
Hit.bBlockingHit;        // :107  false for a touch-only result
Hit.bStartPenetrating;   // :116  query began already overlapping; PenetrationDepth :91
