Summary
Function: llListenRemove( integer handle );| 0.0 | Forced Delay |
| 10.0 | Energy |
Removes listen event callback handle
| • integer | handle | – | handle to control listen event |
Caveats
- On state change or script reset all listens are removed automatically.
- A state change can be used as a shortcut to releasing all listens in the script.
- No error is thrown if handle has already been released or is invalid.
Examples
<lsl> // Listen for one line of chat from the owner, echo it back to them, then stop listening integer ListenHandle; default {
state_entry()
{
// Start listening on channel 0, for text from owner only
ListenHandle = llListen(0, "", llGetOwner(), "");
}
listen(integer channel, string name, key id, string message)
{
llOwnerSay(message); // Echo the message back to the owner
llListenRemove(ListenHandle); // Stop listening
}
}</lsl>
Notes
- It is good practice to remove listeners when they are no longer required, or set them inactive via llListenControl
