zombie detector

[malyczolg]

hello , i make zombie detector
why if I am further than the distance detector see me ?

		detector()
{    
    self.detector = spawn("script_model",self.origin);
    self.detector.angles = (self.angles);
    self.detector setmodel("xmodel/prop_hydrant");
    
    time = 45;
    for(;;)
    {
        players = getentarray("player", "classname");
        for(i = 0; i < players.size; i++)            
        {    
            distance = distance(self.detector.origin, players[i].origin);
            if(distance < 100 && players[i].sessionstate == "playing" && isAlive(players[i]) && players[i].pers["team"] == "axis" && players[i].detector == 0)
            {                    
                players[i].detector = 1;
                iprintlnbold("detect : "+players[i].name);
                //players[i] thread detector2();
            }
            else
            {
                players[i].detector = 0;
            }
        }
        if(time<=0)
        {    
            players = getentarray("player", "classname");
            for(i = 0; i < players.size; i++)            
            {    
                players[i].detector = 0;
            }
                self.detector delete();
                break;
        }
        
        time -= 1;
        wait 1;
    } 
}
