Summary
Function: llRegionSay( integer channel, string msg );| 0.0 | Forced Delay |
| 10.0 | Energy |
Says the string msg on channel number channel that can be heard anywhere in the region by a script listening on channel.
| • integer | channel | – | Any integer value except 0 (which would be open chat, or PUBLIC_CHANNEL). | |
| • string | msg |
Regardless of where the prim is, the message will not travel over region borders.
Caveats
- This function cannot transmit on channel 0, this is a design feature and not a bug.
- If msg is longer than 1024 characters it is truncated to 1024 characters. (Note that in Mono, each character occupies 2 memory bytes).
- A prim can not hear itself, this to prevent problems with recursion. It can however hear other prims within the same object.
Examples
<lsl>default {
state_entry()
{
llRegionSay(25,"This is an incredibly useless program." );
}
}</lsl>
To avoid making your object spam its neighborhood, use llOwnerSay or llInstantMessage.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., <lsl> llRegionSay(-5243212,"turn on");</lsl> Negative channels are popular for script communications because the standard SL 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). The only way to do so prior to llTextBox was to use llDialog which was limited to 24 bytes.
If DEBUG_CHANNEL is used as channel, the script will say msg to the Script Warning/Error window.
If you wish two objects owned by the same person to communicate within a SIM, one idea is to make both scripts compute the channel based on the owner UUID. e.g. :- <lsl>
gChannel = 0x80000000
