Ok I don???t know where to start on this.
What I want to do is make halo have more functions for example.
I want it to ban by name, hash and ip.
If a player shoots me the damage is done to them and not me.
A list of players the server can???t kick or ban.
Some type of player and map voting.
A lot of things that adminmod that counter strike has I want in halo.
I just don???t know where to start is it hooking, sub classing, process injecting I don???t know.
Thank you
