I am thinking about doing a few tweaks to the weapons of jka, and one of my main ideas is to increase the damage radius of the explosive weapons (rocket launcher, thermal det, trip mine, det pack), as well as the amount of damage they do. I peeked inside the weapons.dat file but didn't really see anything relating to these objectives. Any idea how I might go about this, or if its even possible?
For multi-player, you'd need a basic understanding of C, and the JKA MP SDK which can be found on jk3files. Most of the weapon damage/radius values are defined in g_weapons.c in the 'jk2game' project.
