Referencing pawn player

hi, for a project i am designing a tank game and want a tank to be constantly looking at my player but after looking online a lot i haven’t found a solution to referencing my player in c++

ATank* myCharacter = Cast<ATank>(this);

	if (myCharacter)
		FVector targetLocation = myCharacter->GetActorLocation();
		FVector myLocation = GetActorLocation();

		FRotator newrot = (myLocation -targetLocation).Rotation();

		NewRotation.Yaw = newrot.Yaw;

above is what i have at the moment which does nothing as i dont think ifs finding the player and before i put the if statement in it was just crashing, any help/guidance is appreciated and thanks in advance.
