Anti-Cheat Solution for COD2 1.0?

[CaptainSlow]

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;
	level.callbackPlayerConnect = ::Callback_PlayerConnect;
	level.callbackPlayerDisconnect = ::Callback_PlayerDisconnect;
	level.callbackPlayerDamage = ::Callback_PlayerDamage;
	level.callbackPlayerKilled = ::Callback_PlayerKilled;

	level.endgameconfirmed = ::endMap;
}

		spawnSpectator();
	}

	self setClientCvar("g_scriptMainMenu", scriptMainMenu);
}

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!!
