im making a game and so far its been pretty easy, but i ran into a problem detecting when a bullet hits a guy. I duplicated both the bullet and the guy so i figured i could put code into the bullet and nest a do loop inside to test which guy i hit. but the do loop runs too slowly and only detects a collision every once in a while. Is there any way to test if any guy duplicated is hit?
