Hacking a pserver

So I am not sure if this is off topic but does anyone know how to modify a flash client of an rotmg pserver so that you would have godmode and enemies damage themselves?

download jpexs, open the swf file, enter com-company-assamblegameclient-objects, open objectproperties, search player and change to "players" or "enemy", (don't use the exp. option). badabing badaboom i'm done
