You shall use something like this

pawn Код:

public OnPlayerWeaponShot( playerid, weaponid, hittype, hitid, Float:fX, Float:fY, Float:fZ )
{
    if( hittype != BULLET_HIT_TYPE_NONE ) // Bullet Crashing uses just this hittype
    {
        if( !( -1000.0 <= fX <= 1000.0 ) || !( -1000.0 <= fY <= 1000.0 ) || !( -1000.0 <= fZ <= 1000.0 ) ) // a valid offset, it's impossible that a offset bigger than 1000 is legit (also less than -1000.0 is impossible, not used by this hack, but still, let's check for it, just for the future, who knows what hacks will appear). The object with biggest offset is having ~700-800 radius.
        {

            Ban(playerid);
            SendClientMessage(playerid,COLOR_YELLOW,"[ANTICHEAT]: You got Banned form server . post appeal on http://www.goofycrew.proboards.com ");
            SendClientMessage(playerid,COLOR_RED,"****[INFO]pres F8 and upload your pic on imgur.com****");
            return 0; // let's desynchronize that bullet, so players won't crash
        }
    }
    return 1;
}
