About god mode

Iv been wondering about godmode,as i have seen plenty of players not dieng after 2 M107 shots while at 0 health and people just not loosing health,is there anyone here that knows how or can tell me how to do so.I have no coding experience so i cant help what so ever but iv read i think,that someone after being shot a command or something is executed and then they take damage ,there might be a way to block that idk

-Thanks

no one codes hacks for this game
