| - | * message can be a maximum of 1024 bytes. This can convey 1024 ASCII characters, or 512 UTF-8 characters such as á. | + | * Messages sent on channel 0 or on $lct[DEBUG_CHANNEL], are throttled to a rate of about 200 every 10 seconds, per region, per owner/user. |
| + | * $prm[message] can be a maximum of 1024 bytes when translated to [[http://en.wikipedia.org/wiki/UTF-8|UTF-8]]. The allowed number of characters can vary depending on what characters the message contains. For example, it allows: | ||
| + | * up to 1024 UTF-8 characters in the ASCII range such as A or %, | ||
| + | * up to 512 two-byte UTF-8 characters such as И or £, | ||
| + | * up to 341 three-byte UTF-8 characters such as ツ or €, | ||
| + | * etc. or a mixture of them. | ||
| + | * Negative channels are typically used for inter-object communication. | ||
| + | * A script cannot hear anything said by any script within the same prim. This avoids recursion problems. It can hear text sent from a script in another prim within the same object, if it's within range. | ||
| + | * Attached objects in avatars can't be heard by other avatars if the avatars can't see nor hear each other due to parcel privacy settings. They still can be heard by other objects, though. | ||
