Array capacity

The array capacity is larger than the number of "fixed"/"used" corpses to allow the engine to store new corpses at runtime. "Fixed" means that those corpses are never overwritten/deleted at runtime, all new corpses are stored after the "fixed" ones. This means that "fixed" <= "used" <= "capacity".

Bones

Here is one of the few places where the bone count 19 is apparently hardcoded.

I.e., custom characters with weird bone counts won't work. See, e.g., TRIA

What's in a bone?

The transformation matrix (3D rotation/scale/shear/mirror and translation)

can be seen as four 3D vectors X, Y, Z, and R in world space.

If a bone mesh has a vertex at (x, y, z) in its native coordinates,

then the actual position of that vertex in the level will be R + x X + y Y + z Z

That's the transformation defined by the 3x4 transform matrix.

Reminder : the 2nd coordinate of X, Y, Z, and R is the height.

Authoring

The script command make_corpse(filename) creates a separate corpse file in the Oni folder.

The pose of the corpse is taken from the player character. The format is roughly as above.

The contents of the files thus created can then be inserted as elements in a level's CRSA.
