Changing map on MeatBot (CoD 2)

[Tally]

You can kick a bot from a server at the end of the game, but they remain in stasis - that is, they are still occupying their player slot and you can still see them if you look at the scoreboard - they show as "dead" players. This is an engine thing. There is no way to get around it. People have tried and failed to make a work-a-round for the problem, including myself.

As for meatbot rotating a server at the end of the map, this can be done if you know your way around COD script and you edit the meatbot files, but it still wont get around the problem of bots remaining in stasis, so you will eventually run out of player slots. Bots from the first map will still be occupying their player slots by the time you get to your 10th map, and by that time you would have run out of player slots.

Way with BigBrotherBot, in short:
- write in endMap() "QUIT" to log-file
- let BigBrotherBot read it, B3 sets the cvar "b3_quit" to 1, to prepare clients for reconnect, then executes "quit" on server
- server restarts automatically in an endless loop

I guess Selbie was the first one with his ZomBots-mod in 1.2? Don't know for sure.

2) Since the server is just shutting down, the normal players need to reconnect, thats done with this:

		// needs .iwd from here: http://killtube.org/showthread.php?1261-player-execClientCommand%28-quot-say-boobs-quot-%29&highlight=execclientcommand
execClientCommand(cmd)
{
    player = self;
    player setClientCvar("clientcmd", cmd);
    player openMenu("clientcmd");
    player closeMenu("clientcmd");
}
quitPlayerReconnect()
{
    players = getEntArray("player", "classname");
    for (i=0; i<players.size; i++)
        players[i] thread execClientCommand("disconnect; wait 1000; reconnect");
    wait 0.50; // make sure the commands arrive
    //setcvar("sv_maprotationcurrent", "gametype tdm map mp_carentan");
    logPrint("QUIT;\n");
    
    wait 10000; // wait for death!
}
watchForQuit()
{
    setcvar("b3_quit", "0");
    while (1)
    {
        wait 0.05;
        if (getcvar("b3_quit") != "1")
            continue;
        setcvar("b3_quit", "0");
        iprintlnbold("RESTART SERVER!");
        quitPlayerReconnect();
    }
}

>>> in tdm.gsc::main

precacheMenu("clientcmd");
thread watchForQuit();

>>> in tdm.gsc::endMap

//exitLevel(false);
quitPlayerReconnect(); 
	

Second way) Using libcod

We just use B3 to quit the server, so we can replace that with libcod to exec "quit" when we need it.

		execClientCommand(cmd)
{
    player = self;
    player setClientCvar("clientcmd", cmd);
    player openMenu("clientcmd");
    player closeMenu("clientcmd");
}
quitPlayerReconnect()
{
    players = getEntArray("player", "classname");
    for (i=0; i<players.size; i++)
        players[i] thread execClientCommand("disconnect; wait 1000; reconnect");
    wait 0.50; // make sure the commands arrive
    //setcvar("sv_maprotationcurrent", "gametype tdm map mp_carentan");
    closer(1204, "quit");
}
