Main Crate 0.20.0 - 2024-10-12

Added

• A TnuaBuiltinKnockback action for applying knockback that will not be
  nullified even with very high walk acceleration settings (see
  #30)

Changed

• Instead of fixating it to positive Y, Tnua now calculates the up direction to
  be the reverse of the gravity direction (see see
  #40)
• [BREAKING] API changes:
  • (only relevant for custom basis/actions) The up_direction of
    TnuaBasisContext and TnuaActionContext is now a field instead of a
    method.
  • TnuaController method for feeding basis and actions no longer return
    &mut Self (this was always redundant, since they get called from queries
    anyway rather than on freshly created objects, so they don't benefit from a
    fluent API)
  • desired_forward fields of TnuaBuiltinWalk and TnuaBuiltinDash were
    changed from Vector3 to Option<Dir3>.
  • The direction fields of some of TnuaBuiltinDashState's variants were
    changed from Vector3 to Dir3.
