Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Populates an output array with all UPrimitiveComponents from other actors that are currently overlapping any component of this actor. The array is reset before population.

Signature

Parameters

Name	Type	Description	Default
OverlappingComponents	TArray<UPrimitiveComponent*>&	Output array filled with components currently overlapping any component of this actor.	—

Return Type

void

Caveats & Gotchas

• Returns components from *other* actors — not this actor's own components.
• Requires at least one component on this actor to have 'Generate Overlap Events' enabled.
• A TSet overload is available in C++ if you need to avoid duplicate entries.

Example

Log all overlapping components C++

TArray<UPrimitiveComponent*> Overlapping;
GetOverlappingComponents(Overlapping);
for (UPrimitiveComponent* Comp : Overlapping)
{
    UE_LOG(LogTemp, Log, TEXT("Overlapping: %s"), *Comp->GetName());
}
