I did it...both barrels...nice :)
Epicfaic: I...managed to do that too...I just wanted to fire both barrels at once :(
OMG I BUGGED IT AND ITS A MACHINE GUN NOW!!!!! =D =D
When you press ctrl+b in the bottom right corner is the computer. there are tree gaps in the switch area. put nscn in the two outer gaps and leave the middle one open. this will fix the full auto problem.
you need to make the reloading mech more realistic by making the second shell load slower (both shells load at the same time and a real shotgun you usually have to load a shell at a tyme not bothatonce
at least you fixed the bug with shooting 2 bullets at once
if you hold down the trigger on the first shot it makes it full auto (sorry for commenting on it) I kinda like it full auto, the first full auto shottie made on TPT
