I've created cannonballs for use with my ship's cannons, and they're func_physbox's. I've set the explosion magnitude/damage/radius all to substantially high numbers - 400 across the board - but they don't cause damage to the things they hit. They break like they're supposed to, but a func breakable that I shot one DIRECTLY at didn't even get a chip knocked out of it. Also, if it has an explosion, shouldn't there be some sort of effect or sound when it explodes? If any of you have possible answers to these questions, I would appreciate it beyond words.
