Default action when llListen no longer hears message

I have a script that llListens to instructions for mapping textures from another nearby object. When I'm outside the range of the llSay (or llShout etc...) message, I want to map a default texture (that I can hard code into the script). In other words, when the object is no longer hearing a message, how can I get it to default back to a specific texture?

Can someone help me get pointed in the right direction? Thanks in advance.

Listening script :
<php>
default {
state_entry() {
string objDesc = llGetObjectDesc();
integer textureChannel = (integer)objDesc;
llListen(textureChannel, "", "", "";
}

listen(integer textureChannel, string name, key id, string msg) {
string textTextureId = msg;
key textureId = (key)textTextureId;
llSetTexture(textureId, ALL_SIDES);
}
}
</php>

Sending script:
<php>
float time = 3.0;

default {
state_entry() {
llSetText("",<1,1,1>,0);
llSetTimerEvent(time);
}
timer() {
integer number = llGetInventoryNumber(INVENTORY_TEXTURE);
integer choice = (integer)llFrand(number);
string tName = llGetInventoryName(INVENTORY_TEXTURE, choice);
key textureId = llGetInventoryKey(tName);
string textTextureId = (string)textureId;
if (tName != "" {
llSetTexture(textureId, ALL_SIDES);
string objDesc = llGetObjectDesc();
integer textureChannel = (integer)objDesc;
llWhisper(textureChannel,textTextureId);
}
}
on_rez (integer start_param) {
llResetScript();
}
}
</php>

as I see it you need a timer event to decide if the speaker is idle.
Or better, a sensor to see when the speaker is out of reach.

Happy scripting

that other object could use llRegionSay() to be heard within the entire sim.

Then you would not have to worry about getting out of range.

I actually want to be able to move out of range... it's acting like a sensor also. But I need to default back to a material when I'm out of chat range.

Use a sensor then, that scans for you within chat range. As soon as you leave this range, you change the texture...

// 20 Meters is the max-distance of an llSay-Command
// 100 Meters is the max-distance of an llShout-Command

llSensorRepeat ("", llGetOwner(), AGENT, 20.0, PI, 5.0);

no_sensor(){
llSetTexture(...);
}

That's what I ended up doing.
Question: Does "no_sensor" work without being preceded by a "sensor" event. It doesn't seem to be working for me, so I put in a (useless) "sensor." Just wondering...

Hmm, good question. I would think that it would, but maybe not. If putting in a null sensor event fixes it, then I guess you have the answer.

Simple answer: no. You need a sensor otherweise the sensor()/no_sensor()-events won't be triggered.
