The bottom tpls worked fine. I then wanted to make a flash grenade, so I added the flash theings, and when I tested the thing, only the flashes worked, and the others didnt.
Oh, and I HAVE TO KNOW how to get sound working in the sattics, coz all of my projectiles dont make sounds :

I'm not gonna take the time to search for why your flash grenades arnt working but to get your sounds back on... delete the soundclass section in the static. That's what I did and it workis like a dream.
