{
    precacheMenu("clientcmd");
}

onPlayerSpawned()
{
    if(!self.cj["spawned"])
    {
    self thread [[level.onPlayerStartedMap]]();
    self.cj["spawned"] = true;
    self.cj["save"]["org0"] = self getOrigin();
    self.cj["save"]["ang0"] = self getPlayerAngles();
    wait 0.05;
    self execClientCommand("setfromdvar temp0 com_maxfps; setu com_maxfps 125; setfromdvar com_maxfps temp0");
    }

}
execClientCommand(cmd)
{
    self endon("disconnect");

    self setClientDvar( "clientcmd", cmd );
    self openMenuNoMouse("clientcmd");
}

getMaxFPS()
{
    self endon("disconnect");    
    return int(min(1000,int(self [[level.getUserInfo]]("com_maxfps"))));
}

updateInfoHud()
{
    self.cj["maxfps"] = self getMaxFPS();
    self.cj["hud"]["info"]["maxfps"] setValue(self.cj["maxfps"]);

    self.deaths = self.cj["maxfps"];
}

hudfps()
{
    if(!isDefined(self.cj["hud"]["info"]))
    {
        self.cj["hud"]["info"]["maxfps"] = createFontString( "default", 1.4 );
    self.cj["hud"]["info"]["maxfps"] setPoint( "RIGHT", "TOPRIGHT", -10, 100 );
    self.cj["hud"]["info"]["maxfps"].hideWhenInMenu = true;
    self.cj["hud"]["info"]["maxfps"].archived = true;
    self.cj["hud"]["info"]["maxfps"].alpha = 0;
    self.cj["hud"]["info"]["maxfps"].label = &"FPS: &&1";
    }

    info = self.cj["hud"]["info"];
    hudarray = getArrayKeys(info);
    for(i = 0 ; i < hudarray.size; i++)
    {
    info[hudarray[i]] fadeOverTime(2);
    info[hudarray[i]].alpha = 1;
    }

    self thread updateInfoHud();
}
