The code is weird.. ^_^

For such things, a "bool" var is good and has better performance.

pawn Код:

//Global Variable (On top of your script)
new bool:gGMEnabled[MAX_PLAYERS];

COMMAND:god(playerid, params[])
{
    if(Adminstrator[playerid] == 0) return SendClientMessage(playerid, 0xFF0000FF, "You're not an Adminstrator!");

    if(!gGMEnabled[playerid])
    {
        SetPlayerHealth(playerid, INFINITY);
        SendClientMessage(playerid, 0x00FF00FF, "Godmode ON");
    } else {
        SetPlayerHealth(playerid, 100);
        SendClientMessage(playerid, 0xFF0000FF, "Godmode OFF");
    }
    return 1;
}

//And add gGMEnabled[playerid] = false; on player connect/disconnect, as you wish.

EDIT: ahh, too late.. xD
