Hey there, have you checked if PressurePlate or ActorThatOpens is not null? What is that UOpenDoor(); function you are calling? That seems like a constructor.
This is the output im getting from the UnrealEditor Crash log. As soon as I click play the editor crashes.
the only code I added was:
// if ActorThatOpens is in TriggerVolume
if (PressurePlate->IsOverlappingActor(ActorThatOpens))
{
UOpenDoor();
}
Access violation - code c0000005 (first/second chance not available)

Took me 3 weeks, found the solution.
Turns out when I was doing the unreal engine course I duplicated a door which duplicated the C++ file with it, not realizing this when I added code to open the door with a pressureplate i forgot to select the TriggerVolume on both doors, this was what was causing the error and crash.
Thankyou anyway,
Adam
