Just one of those things I keep putting off. There is a default
directory that Aztec will look in for scripts when you explicitly load
them (the /script directory), but no code for doign an auto load.
Probably no more than 10-20 lines of code to do the job.

I agree. Problem is that writing text editors isn't my forte. I put
together a very simple variant of a windows edit box to make a command
window. If I find some nice code laying around for a console window,
I'll happily replace what I did with something better. Suggestions?

There are a couple of ways to do what you want. First (and probably
least useful) is an undocumented function, "stats(...)". You can dump
every symbol in the interpreter with:
js> stats('atom')
all the global ones with:
js> stats('global')
Look at all the methods of an object (the global Scene object is used in
the example) with:
js> stats('Scene')
If you want to see what object are in the scene, you can simply show all
of its properties (shown after creating a cube primitive):
js> for (x in Scene) print(x)
WhiteLightShape
whiteLight
backLightShape
backLight
TimeSegment01
CubeShape
Cube1
Phil has some nice examples below to show other things you can do with
the Scene object. Also, you can refer to the script docs in the
docs/htdocs/webpage directory. [File is script-api.html] That is a
relatively complete description of what has been implemented to date.
Note that it doesn't document writing JavaScript - you can find tons of
resources for that on the web (and better written that I'm going to be
able to do). The docs are for the Aztec specific classes.
Note that adding the LiveConnect classes (to allow running real Java
from JavaScript) is easy and works well. It is not currently enabled
(mostly because I'm not really sure what sort of JRE people might or
might not have installed). If there is a real desire for this, I can
get it plugged in (with extra work it could be an configurable option).
