Rockets have a 'knock-back' value, try fiddling with that.
Yeah I posted that reply awhile ago in some other thread.I'll just rehash it, basicly you make a big thin block as a v3m make the texture on it totaly transparent when fired it should send the person flying back. I wasnt sure if you wanted the person to be damaged but if not make sure it does no damage in the tbl editing.
Isn't it just the mass of the projectile, multiplyed by the speed? I believe all weapons have a mass setting, and of course a speed setting. Upping the mass to about 40 kg with the speed of a bullet would cause some serious bumpage action.... hell 10 kg would probably do for your purposes.
This would also be good for a "gravity gun" effect, like the Grav. Gun from Turok, where you shot it and it was like "a train hitting them"... just create a semi-transparent trail, much like a rocket, only speed it up. Don't make the trail smoke, make it some weird semi-transparent barely visible circle... would create a nice gravity-warpage effect.
you have the right idea. i know i'v tried it on every weapon RF hase only prolem is... i just can't get people to fly backwords more than two feet. maby i'm doing somthing wrong or maby it has to do with the fack that all i know is table editing. which ever the case maby you could mess with around with it and see if you can get it to work
