Getting HPB values from matrix

I frequently need to get the HOB rotation values from a matrix, and I don't like using the workaround of setting a dummy object's matrix with SetMg() then getting the HPB values with GetAbsRot().

Does anyone have the formula handy? Thanks.

  print rot

Ah, yes. How embarrassing. Forgot about that..

Thank you, Scott.

Thanks, Scott, for solving this issue 🙂

Just a link for future readers, here's the docs of utils module, which contains quite a bunch of these little helpers.
