Creating "draggable" door with Blueprint - game crashes

So I’m trying to create door that would rotate based on player mouse input while key ‘E’ is pressed down, but every time I press it ingame it crashes back to editor. Just started learning UE4 so any advices are welcome.

The While-Loop will run until the bool gets false, unfortunately it will never be changed because your program is executing the loop.

Hope this help you :smiley:

PS: Are you sure you want to change the roll? I think you want the yaw to be changed
