Summary
Function: llListenControl( integer handle, integer active );| 26 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Makes listen event callback handle active or inactive
| • integer | handle | – | handle to control listen event | |
| • integer | active | – | TRUE (default) activates, FALSE deactivates |
Caveats
- On state change or script reset all listens are removed automaticaly.
Examples
a small example of an on and off switchable listen by use of llListenControl() <LSL> integer handle; integer toggle; default {
state_entry()
{
handle = llListen(5, "", NULL_KEY, ""); // Establish a listener to listen to anything on channel 5 ...
llListenControl(handle, FALSE); // ... but make the listener inactive for now
llSetText("not listening", <0.0,0.0,0.0>, 1.0);
}
touch_start(integer total_number)
{
toggle = !toggle;
llListenControl(handle, toggle); // Make the listener active or inactive as required
if(toggle)
{
llSay(0, "now listening on channel 5");
llSetText("listening on ch 5", <1.0,0.0,0.0>, 1.0);
}
else
{
llSay(0, "not listening any more");
llSetText("not listening", <0.0,0.0,0.0>, 1.0);
}
}
listen(integer channel, string name, key id, string message)
{
llSay(0, name + " just said " + message);
}
}
