Godmode?

So i was thinking becuase ive seen a godmode user in ca not to long ago and i asked him about that and he said he coded the godmode but he had a vip running too...And he said that hp is server sided but theres another way but he wouldnt tell meh.. That got meh thinking soo I just got the idea of Looking for the Value of Life? Not the Number like 0 - 100 I mean like if ur living or dead so if we would freeze that instead of hp ur hp would go down but you wouldnt die?

What do u guys think?

PS. No flaming

He just took a different route. He didn't have godmode, it was probably that hp hack shit or w/e
