[pre_v2.0.0] Create Collision Objects by mesh

Question

[pre_v2.0.0] Create Collision Objects by mesh

brothermechanic opened this issue a year ago · comments

Describe the bug
Create Collision Objects by mesh don't works (any other options like cube - works)

To Reproduce
Steps to reproduce the behavior:

Run bpy.ops.phobos.create_collision_objects() ("Create Collision Objects")
Select type - Mesh
See error

Error: Python: Traceback (most recent call last):
  File "/home/bm/.config/blender/3.5/scripts/addons/phobos/blender/operators/editing.py", line 1343, in execute
    bpy.ops.object.transform_apply(location=False, rotation=False, scale=True, properties=False)
  File "/usr/share/blender/3.5/scripts/modules/bpy/ops.py", line 113, in __call__
    ret = _op_call(self.idname_py(), None, kw)
RuntimeError: Error: Cannot apply to a multi user: Object "grip_rotator_collision", Mesh "Part__Feature007.003", aborting

Expected behavior
In Phobos v1 it works

Desktop:

OS: Gentoo
Version: ~amd64

Thanks @brothermechanic for your bug reports, this is really a great help, which I appreciate a lot!
Please let me ḱnow whether fc80018 solves your issue.
The commented lines seem to be a residue from an older version. As collision are allowed to use the same mesh as their visual to reduce the size of the exported model. Therefore applying the scale only to the collision doesn't make sense.

@hwiedPro Hi,
Error message has changed

Python: Traceback (most recent call last):

@hwiedPro new error message

Error: Python: Traceback (most recent call last):
  File "/home/bm/.config/blender/3.5/scripts/addons/phobos/blender/operators/editing.py", line 1318, in execute
    origin=representation.Pose.from_matrix(phobos_vis.origin.to_matrix().dot(transform))
TypeError: Pose.from_matrix() missing 1 required positional argument: 'relative_to'

i think collision wants be relative from armature object, but can't find it

Perfect that you have found that. To facilitate more profound SDF support I recently made the relative_to property mandatory for all Poses. I thought I had found all usages but some seem to have slipped through. I'll push the fix asap

Ok, please try again ;)

Maybe I'm doing something wrong ?

Thanks, this was a not yet handled blender color type in the color parser. Should be fixed now.

I consider this as solved, please reopen if not.
