Give the touchplate and all masterswitches in the earthquake the same unique lotag. Give all S.E. sprites a lotag of 2. Each sector will move in the direction that the S.E. sprite is pointing. Vents are very similar to windows, except vents are actually sprites. First make your vent shaft, then place a sprite where you want the vent to go.
Nuke buttons are one of two ways to end a level.
Another way to end a level is to give a sector a lotag of 65535, which will make the level end when the player steps on that sector. Also give the S.E. sprites a lotag of 13. Sometimes, this problem is simply because the ceiling is up too high, or the floor down too low. Make the sector that will be the conveyor, get it to be the way you want it and place a S.E. sprite in it. Give the sprite a lotag of 24 and point the sprite in the direction you want the conveyor to go.
