Negative channels are popular for script communications because the standard Second Life client is unable to chat directly on those channels ("/-xxxx message" won't chat "message" on channel "-xxxx", it will chat "/-xxxx message" on channel zero).

Summary

Function: llRegionSayTo( key target, integer channel, string msg );

Says the text supplied in string msg on channel supplied in integer channel to the object or avatar specified by target

• key target group, avatar or prim UUID that is in the same region
• integer channel output chat channel, any integer value except DEBUG_CHANNEL
• string msg message to be transmitted
Channel Constant Description
PUBLIC_CHANNEL 0x0 Chat channel used to broadcast to a specific user or prim. This channel is sometimes referred to as: open chat, local chat and public chat.

Caveats

  • Messages sent on channel zero[1] are throttled to a rate of <200/10sec, per region, per owner/user.
    • Once the rate is exceeded, all following messages on channel zero will be dropped until the send rate is again below 200/10sec for the previous 10 sec. Dropped messages, despite being dropped still count against the limit.
  • Text is spoken directly to the object or avatar within the same region as the script.
  • Scripts in tasks other than target can not listen for and receive these text messages, with an exception for attachments as described below.
  • Text can be a maximum of 1024 bytes. This can convey 1024 ASCII-7 characters, or 512 UTF-8 characters such as á
  • A prim cannot hear itself, to prevent problems with recursion.
  • Sending text on DEBUG_CHANNEL is not supported
  • Text sent to an avatar's ID on channel zero will be sent to the receiver's viewer.
  • Text sent to an avatar's ID on non-zero channels can be heard by any attachment on the avatar
  • A quick series of messages sent by llRegionSayTo cannot be relied on to arrive at their destination in the same order as sent.

Examples

<lsl> default {

   touch_start(integer num_detected)
   {
       key id = llDetectedKey(0);
       // send a message to the chat window of the avatar touching
       llRegionSayTo(id, PUBLIC_CHANNEL, "You touched this!");
       // send a message to the attachments of the avatar touching
       // example channel: -12345
       llRegionSayTo(id, -12345, "Hello there attachments!");
   }

}

</lsl>

Notes

  • Channel 0 is the PUBLIC_CHANNEL. This should only be used for chat intended to be sent to the viewer.
  • If one object 'says' something to another object (e.g., a button that, when touched, turns on a lamp), it is a good idea to use a very negative channel, e.g.,

<lsl>

   llRegionSayTo("55499a64-45c3-4b81-8880-8ffb5a7c251b", -5243212, "turn on");

</lsl> Negative channels are popular for script communications because the standard Second Life client is unable to chat directly on those channels ("/-xxxx message" won't chat "message" on channel "-xxxx", it will chat "/-xxxx message" on channel zero).
