Hey Freeman97, guess what? I'm 13. AND I CAN'T MOD A COOKIE JAR. Seriously, I think that you should join a modding team and gain experience first. Make a few maps, maybe some custom scripts, some skins, THEN think about modding.
The gun can only pick up soldiers once it's supercharged int the Citadel, and you're supposed to left click that orb, to knock it loose from the generator.
I have the exact same problem, if I kill an NPC in GMOD, even If I'm far away and not looking at it it still crashes. My comp's specs are good enough to run GMOD fairly smoothly.
