Message: 2 new features - Billboarding and model nick names
========================
Billboarding
========================
Billboarding is a technique where you can make something always face the camera
no matter which angle you are looking at it from. This is used in lots of
games both present and past. If you play WOW, this is the technique they use
for the priest bubble for instance. It's just a 2d "halo image" that always
faces you so it looks like a bubble encasing them but it's not. This technique
is also used in games to give a halo effect around light sources. Old games
used to use this technique for bushes and trees, and in wolfenstein 3d it
happened as a side effect of how they rendered all the objects in the game :P
You can turn billboarding on and off for a model by using the script function
SetBillBoarding(). There isnt an interface in the editor for it yet but if you
manually put the command into the _geometry file, that works fine (and when you
save it will still be there).
As an example of this, there are 3 flickering lights on the candles in the
fortune teller's tent that use billboarding.
========================
Model Nick Names
========================
This is a feature where an object can be placed and manipulated in the editor,
and then a nick name can be given to it so that Kent can call up that model
from script by it's nick name to be able to manipulate it. Before this, all
models manipulated in script had to be loaded and placed inside the script file
which isn't editable in the editor.
I put an example of this in the fortune teller's tent. The 3 flickering lights
are each given a unique nick name, and in the script it calls them up by nick
name and manipulates them, even though they were placed in the editor.
There is no way currently to specify a nick name in the editor, but that will
come later, and since Kent will be the one dealing with this mostly, he can
manually give nicknames to objects for now by putting the command in the
_geometry file (which will persist even after a save).
The candles flickering is just crappy programmer art but it's just an example
to show these 2 new features.
Feedback welcome of course :P
