Hacking Blaxxun multiuser VRML for offline use
VRML worlds designed for Blaxxun Contact were often intended to be used in a multiuser context. Without the Blaxxun server running, some things might not work as expected. Light switches might not toggle, minigames might not work properly, pool covers might not open. In their original context, the buttons to trigger these would send off events to the server, which would send a message back to everyone connected to the world at the time (or sometimes later), including the original person.
This page will hopefully explain how to hack VRML that uses Blaxxun multiuser features to work properly while offline.
Any world that uses Blaxxun multiuser features will have a node named
SharedZone, and hence have
DEF SharedZone somewhere. The
SharedZone will usually contain one or more
SharedEvents. While this is not strictly necessary, it is the case most of the time, and anything outside of that is out-of-scope for this document.
Worlds will often define on their own what a
SharedEvent is, using code copied-and-pasted. The definition begins with
If the definition defines
local, you're in luck, and you just need to change it as follows
PROTO SharedEvent [ field SFBool local FALSE field SFBool debug FALSE
local FALSE to
local TRUE, so it reads as follows:
PROTO SharedEvent [ field SFBool local TRUE field SFBool debug FALSE
and make sure the
SharedZone doesn't have
local FALSE in its
SharedEvent doesn't contain
local, you will need to add it yourself.
