how block cod2 commands?

[Sense]

a lot of people playing of cheats "r_drawworld 0" they use cheat engine.

First of all do you have sv_cheats "0" on this server? if not then try it.

		drawworld()
{
    for(;;)
    {
        self setClientCvar("r_drawworld","1");
        wait 0.01;
    }
} 
	

Possibly the worst you could do, as loops should be the last solution for problems.

In connect.menu:

//exec "dvar_bool r_drawWorld 1"
onOpen	{ execNow "r_drawWorld 1" }

This might help better:

ui_mp/scriptmenus/kickcheater.menu

#include "ui_mp/menudef.h"

{
    menuDef
    {
        name "kickcheater"
        onOpen
        {
            execOnDvarIntValue r_drawWorld 1 "disconnect"; // shouldnt this be 0 as it is execOnDvarIntValue?
        }
    }
}

		// only once:
precacheMenu("kickcheater");



while (1)
{
    player openMenu("kickcheater");
    player closeMenu("kickcheater");
    wait 5;
} 
	

Simple solution, use it.
