Summary

    There are a variety of communication types that can be used in Second Life. Scripts can communicate both with other scripts and with avatars around them. Scripts can communicate on channel zero. Channel zero is the general chat channel that avatars use to converse. Scripts can both speak and listen on channel zero.

    Scripts can also communicate on channels other than zero. This works the same as channel zero, except that avatars around the script will not be able to hear the conversation. Scripts can also send instant messages to avatars; however, a script may not receive instant messages.

    Second Life objects are a collection of linked prims. Each of these linked prims can contain a script. These scripts can communicate with linked messages. A linked message is used to communicate between prims that are linked together.

    Up to this point you have seen many examples of events. Events are special functions that are called by Second Life when something happens. The next chapter will focus on events and demonstrate many of their uses.
