Ontopic:
If the buttons work fine when you press and you want them to say, spawn a projectile these are the basic events you should use.
Oncontentstart/started. That happens when the button/door/lever starts moving.
So if you wanted it to shoot a projectile when it goes down/opens/moves, make an event.
Oncontentstart>self>spawnprojectile> 0 0 0 (Wep) 0 0 0 1.000.
Or use oncontent started, they do the same thing with a small amount of time in between.
