Boy! It's been a while since this was talked about. Such a simple
problem and actually nt that simple and pretty tedious to do.
http://www3.telus.net/robbert/temp/rubik.mov
It isn't perfect but I finally managed to do it. :P Each object's
hot point is the center of the cube. Just one group of all the
cubes. I wrote a simple plugin to rotate a selected bunch of objects
all the same. Which is a LOT faster than selecting each individually
and setting it's rotation. It's reacheable with the above link just
trim off temp/rubik.mov and mosey on into the development area.
I still had to manually set the hotpoint to zero on all of the
smaller cubes. So not everything was peaches and cream. Also this
was the first time I actually did some animation. You'll have to
play with the ease in/out values of some of the tweeners. For some
reason spill over in a previous tween happens. It looks like a bug
to me but then this might actually be expected behaviour. In the
above clip you'll see it on some of the blue and red cubes near the
end. They aren't exactly in place but they are not out of place by
much.
