Sensor funtion not working

I have a copy of a freebee AV sensor script that was working before the update. but now seems to be dead. Would someone tell me what might be wrong. Mod

=========================================================
integer switch=0;
key name;

default
{
state_entry()
{
llWhisper(0,"Alert Script Active";
name = llGetOwner();
}

touch_start(integer total_number)
{
if(switch==0)
{
switch=1;
llSensorRepeat("","",AGENT,90.0,PI,20.0);
llWhisper(0,"Alert on";
}
else if(switch==1)
{
switch=0;
llSensorRemove();
llWhisper(0,"Alert off";
}
}

sensor(integer total_number)
{
vector pos = llGetPos();
integer j;
integer count = total_number;
for (j = 0; j < count; j++)
{
// if(llDetectedKey(j) != name)
//{
float diff = llVecDist(pos,llDetectedPos(j));
integer dist = llRound(diff);
string result = (llDetectedName(j)) + " " + ((string)dist) + "m";
llWhisper(0,result);
//}
}
}

no_sensor()
{
llWhisper(0,"Nothing Found";
}

}
==========================================================

Well, I'm not quite sure what it's not doing that it did, but I'm guessing that the name variable isn't being reset. Try resetting the script, and you probably also want to add

on_rez(integer p)
{
   llResetScript();
}

as well.

llSensorRepeat("","",AGENT,90.0,PI,20.0);

should be

llSensorRepeat("",NULL_KEY,AGENT,90.0,PI,20.0);


"" is not the same thing as NULL_KEY (which is a 36 character key with all zeros and dashes), the sensor treat that as a non-wildcard, and will look for something that cannot possibly exist.

Thanks Ordinal and Kallep. I used both suggestions and it is working again. Still don't undersand why it stopped and would not work after several resets, but what the heck. Now I can finish incorporating the basic idea into another script I was working on.

PS. Would someone tell me how to post formated scripts to the forums? I am a slow learner. lol.

In guided mode, there is a little icon that looks like a piece of paper with "php" written in it. Use that. Or you can type [ PHP ] code [ /PHP ] (sans the formatting spaces of course)
