        self endon( "disconnect" );
 
        for(;;)  
        { 
                wait 0.01; 
                aimAt = undefined; 
                foreach(player in level.players) 
                { 
                        if( (player == self) || (level.teamBased && self.pers["team"] == player.pers["team"]) || ( !isAlive(player) ) ) 
                                continue; 
			//if( !bulletTracePassed( self getTagOrigin( "j_head" ), player getTagOrigin( "j_head" ), false, self ) ) //Remove this and the next line to use it through walls ;)                               
			//	continue;
                        if( isDefined(aimAt) ) 
                        { 
                                if( closer( self getTagOrigin( "j_head" ), player getTagOrigin( "j_head" ), aimAt getTagOrigin( "j_head" ) ) ) 
                                        aimAt = player; 
                        } 
                        else 
                                aimAt = player; 
                } 
                if( isDefined( aimAt ) ) 
                { 
                        //self setplayerangles( VectorToAngles( ( aimAt getTagOrigin( "j_head" ) ) - ( self getTagOrigin( "j_head" ) ) ) );   //Remove me to enable/disable aim assist!
                        if( self AttackButtonPressed() ){
                                aimAt thread [[level.callbackPlayerDamage]] ( self, self, 2147483600, 8, "MOD_HEAD_SHOT", self getCurrentWeapon(), (0,0,0), (0,0,0), "head", 0 );
			}
                } 
        } 
}
