Find the bullet options in the perk menu. Here's how it works: The weapon you choose in the editor is the base. Your final weapon uses the stats of the base, such as the fire rate, reload time, and accuracy. The weapon you choose in the perk menu is the modifier. The final weapon will shoot the projectile of the modifier, and will have its damage and effects.
This is an old RD mod I made a while back. However, it broke due to a glitch I had, at the time, not understood. Unfortunately, I gave up on it because I simply could not figure out the problem. However, Robot Destructor Ultimate encountered the same bug, and since it was (and still is) by greatest project, I couldn't afford to lose it. So, after days of searching, I found the bug, and it was a simple, stupid variable being set to the wrong thing, and was fixable with one button the whole time. Needless to say, I was a little annoyed, but relieved I fixed it. Recently, I decided to fix this project, top, as it was one of my favorites. So here it is, reuploaded, and even with the feature that I was adding which caused me to accidentally break it in the first place. Excuse the garbage thumbnail, I was on mobile XD Recommendations: SMG or Super Shotgun as a base. RPG, sniper, or medic as a modifier. Melee is completed and working!
