Notify actor overlaping

Development Programming & Scripting

If you want to use OnComponentBeginOverlap(), you will need to use Delegates.

Step1: Register your PrimitiveComponent to receive the delegate broadcast

YourComponentPrimitive->OnComponentBeginOverlap.AddUniqueDynamic(this, &YourComponent::CapsuleTouched);

Step2: Create the function to handle the delegate call.

void YourComponent::CapsuleTouched( AActor* Other, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult )

Now you have any information you need about the actors overlapping each other.

Step 3: Make sure to clean up your delegates when the actor is removed

if (YourComponentPrimitive->OnComponentBeginOverlap.IsBound())
	{
		YourComponentPrimitive->OnComponentBeginOverlap.RemoveDynamic(this, &YourComponentPrimitive::CapsuleTouched);
	}

Hope that helps =)
