AActor::IsOverlappingActor

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Returns true if any component of this actor overlaps any component of the given actor. Checks against the currently cached overlap state, not a live physics query.

Caveats & Gotchas

• The result depends on the cached overlap list, not a real-time physics query. If UpdateOverlaps() hasn't been called after a non-swept move, this can return stale results.
• Both actors must have bGenerateOverlapEvents enabled on at least one overlapping component pair for the overlap to have been registered in the first place.
