Listen only in 5m range

Is it possible to have an object only listen on all and any channels just within a 5m range? If so how?

no

There isn't any way to set the range that triggers a listen event but you can check the distance of the object after the event is triggered. It's kinda tricky but you could sensor for the person/object that spoke and find its coordinates. Then use llVecDist to find out if it's more than 5m away. If it is, ignore it.

Even with that you can't listen to all channels. There's a limit of 64 listeners, there's a lot of channels. I could probably work it out, but I'll lay long odds you'd crash the sim just from the listeners. Adding in the sensors to check out the range, bye bye sim for sure.

How to find a persons/objects coordinates?

Use an llSensor call that only selects the key of who/whatever you heard speaking, then use llDetectedPos(0). But it's easier just to limit the range of the sensor.

e.g.

gMessage = "";

...

listen(integer c, string name, key id, string msg)
{
   gMessage = msg;
   llSensor("", id, AGENT, 5.0, PI);
}

sensor(integer n)
{
   llOwnerSay("Within 5m, position " + (string)llDetectedPos(0) + ", message was " + gMessage);
}

no_sensor()
{
   llOwnerSay("Not within 5m");
}

Which is why I just said no - any solution thaat is workable is gonna make me wanna kill whoever is using it hee hee

Are you wanting to listen to all channels in order to discover what channel some particular communications are occuring on?

You can't listen to all channels at once, but you can listen to a fairly large range without too much effort or noticable hit to sim performance. If you don't find anything in one range, switch to the next, repeat until you find what you're looking for. That way, rather than lagging the sim with a "super-scanner", you just take a little more time to find what you're looking for.

My answer would have matched yours. But, after the next poster talked about how to make a listener that ignored things more than 5m away, I thought it worth explaining that the other part of the equation wasn't really doable either.

Hi Thorne

Channel numbers are signed 32 bit integers ranging +- 2 billion. You may catch fixed numeric low channel transmissions but you'd have to be very lucky to catch randomly selected channels. I use those random channels for dialog boxes from multiple prims.
