- Improve arms attachment
The arm bones were at an angle, so that the bones were difficult
to orient correctly, as unintuitive combinations of angles
would be needed to get the default orientation, or any other
acceptable orientation. Moreover, a simple rotation of the arm,
e.g. forward, would require all angles to be adapted, instead
of just one.
The ends of the arms bones were moved from touching the body, to
the center of the arm, at an equal distance from the sides of the
arm and the shoulder; the arm bone is now in the center of the arm.
- Fix body rotation
The body was rotated 180° while the rest wasn't, leading to
strange results when setting bone positions manually.
- Fix default rotation of limbs (manually positioning them in
their default position would require an 180° rotation).
Is is not know how this was fixed. Maybe just because the
model was re-exported.
- The bone of the cape was moved to the center of the cape (it was
at the edge). For some reason this fixed the 180° rotation of the
cape when it was manually positioned (similar to previous issue).
The changes above fix most of the issues mentioned in #1376
- Add a player-model-specific workaround for the problem described in:
https://github.com/minetest/minetest/issues/2813#issuecomment-198796927https://github.com/minetest/minetest_game/pull/1392#issuecomment-261669915
During walking, attached tools would randomly switch hands. Walking also
happens to be the only animation where the body does not move. Making the
body move an imperceptible amount makes the issue disappear for the player
model.
- Fix body vertex group: it no longer includes parts of arms and legs
Thanks to @stujones11 for these last two changes.
