Hi,
For your player, you will need to make sure it's set up like on the no exit demo. Not easy, but pay attention to the component attached to the no exit player and spot the difference between yours, or better, import the player from no exit into your game and see if it works.
as for the "play animation" action, once the animation is played, the action is then idling, so it won't have any impact if you increase the number of doors to high numbers. In short, the "play animation" fire once the animation and then do nothing.
bye,
Jean
