Crash on SetActorRotation()

Development Programming & Scripting
1

Hey guys,

Bit of a strange one. Whenever the 1 line function below is called, the editor crashes. OpenAngle is set to 90.f and Owner is set in BeginPlay with GetFirstPlayerController(). Any ideas?

void UOpenDoor::OpenDoor()
{
	Owner->SetActorRotation(FRotator(0.0f, OpenAngle, 0.0f));
}

if your game crashes your owner ptr is not valid.

To be sure try this:
if(Owner)
{
Owner->SetActorRotation(FRotator(0.0f, OpenAngle, 0.0f));
}

Thanks for the quick reply! That’s stopped the crashing but interestingly that means that

AActor* Owner = GetOwner();

in BeginPlay() doesn’t set Owner. Is there a circumstance where GetOwner() doesn’t work?

That’s the case whenever an uobject isn’t owned by anything. You have to set the owner manually. Actor components do that for you.

:frowning:
it is an actor component, oh no!

Are you creating the component in the actors constructor?

ah, there it is. both there and the header file. Such a noob!

Thank you
