I want to make a trap door in the floor that can be opened by pressing the "use" button(E). I want the door when your above it to open upwards when you press "use". Then when you are under it I want it to fall down from the bottom. I want it to have a timer for it to automatically close too because it will be held by a spring so when u open it from underneath and pull it down there will be a spring that will push it up then when ur above it will just fall down to where the spring holds it in place. So is this possible?
