Other than old, this aimbot uses colors to identify its target which is a bad method (by bad i mean slow and higher chance to be inaccurate). The best way to make an aimbot is to get your player coordinates then loop through your enemies coordinates and calculate what your pitch and yaw should be so that it is aiming at your enemy. It is a lot faster then this aimbot and the only problem is just visibility check.
Look a CA hack with some esp + aim function O.o
