> How can I simulate the shockwave of an explosion? A very quick hack that I was using is to place a body-less sphere (only for collision) in place of explosion. Grow the sphere for a short time, then shrink it or just delete it. Probably it's very far from being "correct" :) Aras Pranckevicius aka NeARAZ http://www.gim.ktu.lt/nesnausk/nearaz/
