llRegionSayTo

Summary

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

0.0	Forced Delay
10.0	Energy

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
• string	msg

Caveats

• 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.
• There is a per-destination throttle of 200 messages sent over 10 seconds on channel zero. Thereafter, there is also a per-sending-object throttle of 100 messages on channel zero over 300 seconds (5 minutes). This throttle is relevant only after the first throttle is activated. Messages sent on channels other than zero do not trigger the throttle but, once it is triggered, the block applies to all channels. The block is region-wide and applies to all objects with the same owner. The block apparently lasts until the region is restarted.

Examples

default
{
    touch_start(integer num_detected)
    {
        key id = llDetectedKey(0);

        // send a message to the chat window of the avatar touching
        llRegionSayTo(id, 0, "You touched this!");

        // send a message to the attachments of the avatar touching
        // example channel: -12345
        llRegionSayTo(id, -12345, "Hello there attachments!");
    }
}

Notes

• 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.,

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

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).

• Messages sent on channel zero via LLRegionSayTo() are blocked after 200 messages on to the same destination in a 10 second period. After this throttle is activated, there is a further throttle, on objects belonging to the owner of the object that triggered the first throttle, of 100 messages per object over 5 minutes (see https://jira.secondlife.com/browse/BUG-5457). The block is region-wide and applies to all objects belonging to the owner, so if a script triggers the throttle, all objects in the same region belonging to the same owner will also be blocked. Messages sent on channels other than zero do not trigger the throttles. The throttles apparently reset only when the region is restarted.

Therefore, llRegionSayTo() is unsuitable for (say) verbose script debugging, and even moderate use can break users' content completely unrelated to the script for an indeterminate (and potentially very long) period of time. Consider using llOwnerSay() for debugging instead or, if this not appropriate, try llRegionSayTo(avatar, non-zero-channel, message) and have an attachment relay the message using llOwnerSay().
