There’s a note at top of video for fix when Unreal crashes, this is code put in and it works…
// Called every frame
void UOpenDoor::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
// poll the TriggerVolume,
//if the ActorThatOpens is in the volume, then
if (PressurePlate && PressurePlate->IsOverlappingActor(ActorThatOpens))
{
OpenDoor();
}
}
