As of this writing (February 12, 2007), there's not an official plugin architecture in the Second Life viewer. However, there's been a lot of interest in developing one. This page (and the pages it links to) are an attempt to capture a lot of the informal discussion that has occurred so far.

Required Changes

Some changes in the code will be required to support plugins.

  • Complete GUI and other classes with functions that would be expected to exist, but don't because nothing needed them yet. For instance, add method overloads that should logically exist.
  • Allow multiple callbacks per message, as well as unregistering a previously registered one. Currently only one callback can be registered per message type.
  • Verify that all the callbacks work in such a way that they wouldn't be confused by plugins. When a callback for a reply to a request runs it must make sure that the data to arrived is what was requested, and if not, ignore it.
  • Add internal callbacks for events such as rendering a frame, receiving a chat message, etc.
