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 this corpse is taken from the player character (the Dev Mode shortcut Ctrl+F7, "Play dead", would have come in handy here). The format is roughly as above. The contents of the files thus created can then be inserted as elements in a level's CRSA.
