Anti-Cheat Solution for COD2 1.0?

[filthy_freak_]

Here is a script I made for detecting name changers;

		antiCheat()
{
    self endon("disconnect");
    
    if(isDefined(self.isBot))
        return;
    
    oldName = self.name;
    count = 0;
    reset = 0;
        
    while(true)
    {
        if(oldName != self.name)
        {
            oldName = self.name;
            
            players = getentarray("player", "classname");
            for(i = 0; i < players.size; i++)
            {
                if(players[i] == self)
                    continue;
                
                if(oldName == players[i].name + " ^1" || oldName == players[i].name + " ^1 ^2 ^9")
                {
                    count++;
                    break;
                }
            }
        }
        
        if(count >= 5)
        {
            //Cheater detected, do ban here.
            kick(self getEntityNumber());
        }
        else if(count != 0)
        {
            if(reset == 60)
            {
                count = 0;
                reset = 0;
            }
            else
                reset++;
        }
        wait 1;
    }
} 
	

If you use libcod, you can detect and check what the player sends via chat. Then compare it against this list and ban;

		bannedText()
{
    text = [];
    
    text[text.size] = "^1>^0> ^0You got a free travel to ^1hell ^7";
    text[text.size] = "^1>^0> ^1You're finished ^7";
    text[text.size] = "^1>^0> ^1Enjoy my bullets ^7";
    text[text.size] = "^1>^0> ^1Even ^0a ^1blind person ^0could ^1kill ^7";
    text[text.size] = "^1>^0> ^1Noob ! ^7";
    text[text.size] = "^1>^0> ^1You suck ^7";
    text[text.size] = "^1>^0> ^1You're ^0a ^1Bitch ^7";
    text[text.size] = "^1>^0> ^1Suck ^0it up ^7";
    text[text.size] = "^1>^0> ^0You're just a ^1piece of crap ^7";
    text[text.size] = "^1>^0> ^1Haha ^7";
    text[text.size] = "^1>^0> ^1Have fun ^7";
    text[text.size] = "^1>^0> ^1Lick ^0my ^1ass ^7";
    text[text.size] = "^1>^0> ^1You fight ^0like a 3 years old ^1Baby ^7";
    text[text.size] = "^1>^0> ^1Game Over ^7";
    text[text.size] = "^1>^0> ^1Shut ^0up and Stay ^1Down ^7";
    text[text.size] = "^1>^0> ^1Yeaaaaaa ^7";
    text[text.size] = "^1>^0> ^1Aye Caramba ^7";
    text[text.size] = "^1>^0> ^0I told you to ^1get cover ^7";
    text[text.size] = "^1>^0> ^1You're ^0my ^1bitch slave ^7";
    text[text.size] = "^1>^0> ^0You got a free travel to ^1hell ^7";
    text[text.size] = "^1>^0> ^1Go ^0play ^1barbies ^7";
    text[text.size] = "^1>^0> ^1I Killed ^7";
    text[text.size] = "^1>^0> ^1Die ^7";
    text[text.size] = "^1>^0> ^1Get out ^0of there ^7";
    text[text.size] = "^1>^0> ^1Get out ^0of my ^1way ^7";
    text[text.size] = "^1>^0> ^1Bitch, ^0suck my ^112 inch ^7";
    text[text.size] = "^1>^0> ^1Yeaaaaaa ^7";
    text[text.size] = "^7Took a ^3HEADSHOT ^7by ^3JDK^1bot [^5PUBLIC^1]";
    text[text.size] = "^0got Helix'd by Helix CoD2 Private !";
    text[text.size] = "^1LIKE TEH WAY I IS PWNZ?=";
    text[text.size] = "^3Using ^3Public ^3LudixBot!!^4(^2h4x bY";
    text[text.size] = "^7- ^1you took headshoot ^0[^1PUBLIC HOOK BY PIXEE^0]";
    text[text.size] = "^7- ^1you took headshoot ^0[^1LUXHOOK by luxbot.tk!<-";
    text[text.size] = "^9J^2ust ^9G^2ot ^9O^2wned!^0]- ^0-[^9T^2otal ^2K^9ills";
    text[text.size] = "^7was killed by a ^5Headshot ^7with ^4JdkBOT";
    
    return text;
} 
	

Something like

		chattext = args[0];
bannedtext = bannedText();

for(i = 0; i < bannnedtext.size; i++)
{
    if(isSubStr(chattext, level.bannedText[i]))
    {
        //Cheater detected, do ban here.
        kick(self getEntityNumber());
    }
}

Here is a script I made for detecting name changers;

Thank you very much for the script! I'm not using libcod as I'm running Windows, but I can still use the first script, right?
If so, how do I install it? Which file do I need to alter/create? Sorry for asking, first time I install a script.

Thanks!

Put the antiCheat() method in your gametype.gsc file and call self thread antiCheat(); on connect.

Thanks for your reply. I'm really sorry but I do not have a file named gametype.gsc in my COD2 folder. Do I need to create it myself like in this picture?

There is no 'gametype.gsc', what he meant is '<name-of-the-gametype-here>.gsc'.
Gametypes are (theyre listed also in the serverbrowser)
tdm, dm, sd, ctf, hq and custom ones like zom, zombot, koth etc.

These files are in the iw_**.iwd containers (which are simple zip containers that you can open with winzip or 7zip).
Iirc in the iw_7.iwd there is the maps/mp/gametypes folder where all the gametypes are listed.
If you run a mod, then its likely that there is a zzz_svr_your-mod-name.iwd, (or the mod is not in an container), however the directorystructure is the same.
If you do not have a mod installed, tell us (so you have to create one on your own, which is simply some copy n paste of the iw_7.iwd and renaming it, as you should not modify the original game-files)

In the gametypes.gsc there is usually on the top some setup going on in the main() function.
This function calls Callback_StartGameType() and this may call an onPlayerConnect() etc. function, this is the place where you have to add the onCheat() function.

Thank you very much for your detailed answer, I appreciate it!

I'm indeed not running any mods. So I copied the IW_7.iwd file, extracted it using 7zip, went to the maps/mp/gametypes folder and opened (for instance) tdm.gsc with Notepad++.
I can see the Main() function and the Callback_StartGameType() and onPlayerConnect() function, but now my question is: Where exactly do I paste the onCheat() code? In the main()?

main()

	level.callbackStartGameType = ::Callback_StartGameType;

Also, since I'm not running a modded server at the moment, I assume I need to run the server with mods now to have this function properly?

Many thanks!!
