Make a 1 BLOCK DOOR using only 1 BLOCK
Wrench it go to events set to wait for : trigger
Add another event named door Decolide and invisible.
Put a button or something and wrench put trigger and whatever you want
Set this blocks group name to the same group name as the door
Hit the button and there you go instant door..
