Use The Gate Function

The open and close will allow you to use the (Interact Key) without messing with that specific object For example if you look at my picture this opens and closes a door, using the Move component to function. it works like this the player walks into the box trigger (Gate Opens) player presses E then it fires into flipflop A first which opens the door and it moves the door and if player presses E again while stangin in the box trigger the door will close again. Gate helps make it so that this function will only work if the player is standing in the Box Trigger
