Hey, would physics work in weapons maybe like say for the projectile in a grenade launcher? and if so, anyone got any how-to's? I use commercial A6 so It would probably need to be so that the launched grenade would need to explode before the next one could be fired.

Yes, it can be used for weapons. My suggestion on how to do it (this will save you from some major vector calculations):

First create the entity at the desired postion and then rotate based on players pan and tilt of aiming. Then just apply a central force to the object to move it.

With the right force and settings it should react like a real grenade launcher.

You could even do this with shell codes in A5.

ok, but does anyone have any ideas how to code such a thing?
