UKismetSystemLibrary::CapsuleOverlapActors

function Engine Blueprint Since 4.0

#include "Kismet/KismetSystemLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Finds every actor whose collision overlaps the given axis-aligned capsule.

Caveats & Gotchas

• Forwards to CapsuleOverlapActorsWithOrientation with FRotator::ZeroRotator.
• HalfHeight is measured from the capsule's center to the tip of a hemisphere cap (per the header comment), not the half-height of just the cylindrical section — it already includes the caps.

Signature

static ENGINE_API bool CapsuleOverlapActors(const UObject* WorldContextObject, const FVector CapsulePos, float Radius, float HalfHeight, const TArray<TEnumAsByte<EObjectTypeQuery> > & ObjectTypes, UClass* ActorClassFilter, const TArray<AActor*>& ActorsToIgnore, TArray<class AActor*>& OutActors)

Parameters

Name	Type	Description	Default
WorldContextObject	const UObject*	Object used to resolve which UWorld to run the query in.	—
CapsulePos	const FVector	Center of the capsule in world space.	—
Radius	float	Radius of the capsule's hemispheres and cylindrical section.	—
HalfHeight	float	Half-height of the capsule, from center to the tip of a hemisphere cap.	—
ObjectTypes	const TArray<TEnumAsByte<EObjectTypeQuery> >&	Object Types (Project Settings > Collision) to restrict the query to.	—
ActorClassFilter	UClass*	If set, only actors of this class or subclasses are returned.	—
ActorsToIgnore	const TArray<AActor*>&	Actors excluded from the results.	—
OutActors	TArray<AActor*>&	Returned array of overlapping actors. Unsorted.	—

Return Type

bool

Example

Find overlapping actors around a capsule C++

TArray<TEnumAsByte<EObjectTypeQuery>> ObjectTypes;
ObjectTypes.Add(UEngineTypes::ConvertToObjectType(ECC_Pawn));

TArray<AActor*> ActorsToIgnore;
ActorsToIgnore.Add(this);

TArray<AActor*> OverlappingActors;
UKismetSystemLibrary::CapsuleOverlapActors(this, GetActorLocation(), 34.f, 88.f, ObjectTypes, nullptr, ActorsToIgnore, OverlappingActors);
