New mesh animation system
Browse files Browse the repository at this point in the history 
Scrapped the old crappy animation system because it made absolutely
no sense and was horribly limiting. The new system is based on two
mechanisms. The first is a new section in PIE files called ANIMOBJ
that modify the position, rotation and scaling of frames for the
given mesh level. The second is a new directive in PIE files called
EVENT which tells the game to use a different model instead when
the given event is triggered for the game object, such as burning and
moving.

There used to be three animations systems in the game - texture
coordinate flipping, key frames, and skeletal. Key frames are now
merely expressed in terms of skeletal frames in which scaling for
all but the key frame is set to a fixed -1000, which disables the
frame entirely.

The reason that this information went into the PIE files is simply
because it was easier. Making a new file format when there is current
exactly two models with proper animation (supercyborg and oil derrick)
made little sense. In the long run we should reconsider the whole PIE
format.

Scaling now actually supported, in all three dimensions. It used to
possible to specify in ANI files, but was never used. Each level can
now have separate animation framerates and cycle counts (how many
times to run an animation, zero for infinity).

Currently implemented for structures and droid bodies (which includes
cyborg feet).

Currently supported animation event types: Movement, power generator
active, firing, and dying. All units can now have a dying animation.
However, babas no longer run around screaming before they die - this
was just too hard to generalize (and was pretty much broken anyway).

See documentation in doc/ for further details.
