a way wasier way to do this (i made an elite plasma sword instead of a lightsaber) is to change the firing rate of a weapon to like 99999999 in HMT and put the damage WAY up, and make it so the projectile dies after like 3 feet (like the needler(it explodes after a few meters) Again in HMT)
and there ya go! if ya wanna be real thurough, (sorry canttype) you could change the model of the weapon to look like the end of a lightsaber or the part the elite holds if yer doin' the sword. Anyway...keep up the good work!
