Begin Play Doesn't Fire

Hi.

I made a blueprint deriving from a c++ class.
I try to add a new widget variable when begin play fires, but it doesn’t.

Here is the BP:

when the game starts, it doesn’t print “Hello”…

the code for begin play in the C++ class:

Super::BeginPlay();

	gameStatePtr = (AVikingKingGameState*)(GetWorld()->GetGameState());
	gameModePtr = (AVikingKingGameMode*)GetWorld()->GetAuthGameMode();

UE4 is binary, ver: 4.7.6-2513093

Anyone? Staff?

What class? Is it an AActor? Can i see your header file and the entire begin play function? Give us more info so we can help, or don’t expect too much. :slight_smile:

@Azarus That was the entire begin play. Also it derives from another class which is a base building class which derives from AActor

I am pretty sure that you missed a Super::BeginPlay(); in one one of your classes? Check ABuildingsMain if it calls the BeginPlay function of its parent class.
By the way the ReceiveBeginPlay(); calls the blueprint event, adding that to your code should work.

@Azarus you are right. I did miss it. I feel so stupid :/. write that as an answer and I’ll approve.
