Summary

Function: llListenRemove( integer handle );

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

// 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
    }
}

Notes
