HelpHow does Propkill Help work?

I installed a new Garrys Mod hack, HackBETA, a Remake from AHack. I want to Propkill someone, but the prop flys, without killing someone randomly, how can i set that the prop flys on a enemy?

with the power of the gods you can do anything you want
all you need to do is believe in yourself
but knowing Lua will probably be the biggest help

Woah, be careful with that hack man. I know a friend that got arrested for using that hack it can do some serious things.
