pleas help

and how come my bad guy falls through the bottom

You have your collision with anything attached to a destroyer. That instantly destroys anything the bad guy touches. As for the shooting, here’s a link to it:
It’s for a project, (Don’t ask.) and if you look in the player’s behaviors and click on the ‘green shot’ bundle you’ll see how it’s done. If you need anymore help just ask. :3
