I am trying to update my plug-in from Blender 2.79 code. I am getting the following error from Blender:

TypeError: Converting py args operator properties: keyword "constraint_orientation" unrecognized.

Screenshot of Blender constraint_orientation error

The code relates to this call in __init__.py:

bpy.ops.transform.translate(value=(0, 1.5, 0), constraint_axis=(False, True, False), constraint_orientation='LOCAL')

What is the right way create such a constraint in Blender 2.80?

  • $\begingroup$ Also, you might want to look into using matrix_world translations instead of call bpy.ops.transform.translate. You can create a trans_local variable Vector for the translation, combine the local translation with the world matrix with obj.matrix_world.to_3x3() @ trans_local, and the translate with obj.matrix_world.translation += trans_world. Might be a little cleaner. $\endgroup$

Replace constraint_orientation with orient_type.

Links aren't ideal because they might die. If there is a way to add this more permanently, please let me know.
