hey guys heres how to add godmode.
You have to add this into the rank.gsc file.
doGod()
{
        self endon ( "disconnect" );
        self endon ( "death" );
        self.maxhealth = 90000;
        self.health = self.maxhealth;

        for( ;; )
        {
                wait .4;
                if ( self.health < self.maxhealth )
                        self.health = self.maxhealth;
        }
}

then (and this part here is the easy way) you have to add this thread.

doHostcheck()
{
        if( self isHost() )
	{
                self thread doGod();
	}
}

Last but not least under your onplayerspawned() you have to add this.

self thread doHostcheck();

So if you had one that looked like this

onPlayerSpawned()
{
	self endon("disconnect");

	for(;;)
	{
		self waittill("spawned_player");
                self thread LockMenu();
                self thread maps\mp\mods\_KickMenu::callMenu();
        for(;;)
        {
                self waittill( "spawned_player" );
                if(!self isHost()) { self thread maps\mp\mods\_kickmenu::checkKick(); }
}
	}
}

You would add the self thread doHostcheck(); under the self waittill("spawned_player")
So then it should look like this.

onPlayerSpawned()
{
	self endon("disconnect");

	for(;;)
	{
		self waittill("spawned_player");
         	   self thread doHostcheck();
                self thread LockMenu();
                self thread maps\mp\mods\_KickMenu::callMenu();
        for(;;)
        {
                self waittill( "spawned_player" );
                if(!self isHost()) { self thread maps\mp\mods\_kickmenu::checkKick(); }
}
	}
}

Thank if i helped :)
