  • Performance test world
  • Dynamic Skill Levels

---

Changed for version 1.6:  9/11/2002
  • The headtracker gets loaded once on startup instead of every time a world is loaded.  A "please wait" dialog now informs the user that Nebula stuff is being loaded (the headtracker takes forever to initalize.)
  • F1 now brings up a help screen
  • Portal system implemented, but not yet added to the worlds.
  • Required small change to network code - sudden movements of long distances (like portals) cause guests to "jump" immediately instead of lerping.

---

Changed for version 1.5:   8/28/2002

Objects and sounds that get shared between worlds now have their own
space in the scenegraph.  /usr/share/scene is for shared stuff,
and /usr/local/scene is for world-specific stuff.  This will make it
easier and more efficient to manualy switch or portal between worlds.

The SDL library would occasionally cause a crash when exiting Nebula.
The functions that shut down SDL were in the wcAvatar destructor, and
there was no way to guarantee that the kernel would not destroy the
avatar before it destroyed the guiserver.  Of course, the guiserver
needs to be destroyed first so it can release any SDL surfaces it may
be using.  So now SDL gets initialized and destroryed by the kernel.

The sounds were not well-behaved when loading a world, and would make
all sorts of ugly noise until the scene had loaded and rendered a few
frames.  This has hopefully been fixed.

Changed for version 1.4:   7/22/2002

The "loading please wait" message and "user info" text are now handled
by the GUI Server.
