Drop a model

[ORDI]

mhm where is the problem ? i would like every 0.1 second, the model move according to my vision.

		sentry()
{
    self endon("disconnect");
    self endon("killed_player");
    
    self iprintlnbold("^7Press ^3[^7F^3] ^7to Place a sentry");
    sentry = spawn("script_model",self geteye()+(0,0,-40));
    sentry setmodel("xmodel/ordi_sentrygun");
    s1 = undefined;
    
    for(;;)
    {
        wait 0.1;
        trace = bullettrace(self getEye()+(0,0,-40), self getEye()+(0,0,-40)+maps\mp\_utility::vectorScale(anglesToForward(self getPlayerAngles()), 100000), false, undefined);
        
        if(trace["fraction"]!=1)
        {
            if(isdefined(trace["entity"]))
            {
                if(isplayer(trace["entity"]))
                {
                    s1=trace["entity"];
                    sentry.origin = s1.origin;
                    s1 linkto(sentry);
                }
            }
        }
        
        if(self usebuttonpressed())
        {
            sentry unlink();
            s1=undefined;
            self iprintln("Sentry placed!");
            self thread activation_sentry();
            break;
        }
    }
}
