llSay

Summary

Function: llSay( integer channel, string msg );

0.0	Forced Delay
10.0	Energy

Says the text supplied in string msg on channel supplied in integer channel.

• integer	channel	–	output chat channel, any integer value
• string	msg	–	message to be transmitted

Channel Constant		Description
DEBUG_CHANNEL	0x7FFFFFFF	Chat channel reserved for script debugging and error messages, broadcasts to all nearby users.
PUBLIC_CHANNEL	0x0	Chat channel that broadcasts to all nearby users. This channel is sometimes referred to as: open chat, local chat and public chat.

Caveats

• Messages sent on channel zero^[1] and DEBUG_CHANNEL are throttled to a rate of <200/10sec, per region, per owner/user.
  • Once the rate is exceeded, all following messages on channel zero or DEBUG_CHANNEL 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 spoken can only be heard within 20 meters of the speaking prim (rather than the root). This is contrary to how the event listen works, where a message can only be heard by any prim in the object if and only if the root prim is capable of hearing it.
• Text can only be a maximum of 1023 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()
   {
       llSay(0,"Hello, Avatar!");
   }

}</lsl>

To avoid making your object spam its neighborhood, use llInstantMessage or llOwnerSay.

Notes

• Channel 0 is the PUBLIC_CHANNEL. Everyone can hear chat transmitted on this channel. All other channels are private channels (not sent to users, with the exception of DEBUG_CHANNEL).
• Consider using llInstantMessage, llOwnerSay, or the DEBUG_CHANNEL for debugging purposes. If DEBUG_CHANNEL is used as channel, the script will say msg to the Script Warning/Error window.
• 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>

   llSay(-5243212,"turn on");

</lsl> Negative channels are popular for script communications because the 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.
