I'm impressed dude! That looks nice! ok, first- ball hitting the glass, change your glass height. Click on an empty area of the pf, and "Physics". I changed it to 240. Next, uncomment the add ball sub, it's constantly giving you an extraball. Next, create a light called shootagain as it's called in the script and you'll get an error without it. Even if you don't use the shootagain light, make it radius 1 and you won't see it. After that it works fine.
