Running script produce an error

[Almaghasilah]

Hello,

I am trying to run a function from a library called Goo (https://github.com/smegason/Goo) in a Python script. Here is my code:

import bpy
from goo import goo 
from importlib import reload
reload(goo)
 
for collection in bpy.data.collections:  # loop through the existing collection
      for objs in collection.objects:
            bpy.data.objects.remove(objs)
      bpy.data.collections.remove(collection)

cA_collection = bpy.data.collections.new("A_Cells")
bpy.context.scene.collection.children.link(cA_collection)
cA1 = goo.Cell("cell_A1", loc=(2, 2, 0), flavor="ico_sphere")
goo.make_cell(cA1)
obj = bpy.context.active_object
bpy.ops.collection.objects_remove_all()
bpy.data.collections['A_Cells'].objects.link(obj)

Every time I run it, it would produce this following error

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'name'
Location: /Applications/Blender.app/Contents/Resources/3.2/scripts/modules/bpy/ops.py:113`

However, when I run it on Blender's Scripting tab, it runs fine and never produce the error above.

I am wondering if anyone has the same issue before.

Hi @Almaghasilah,
this seems like issue of the goo library. You can see that in the output the function make_cell expected some cell.data to exist, but it is None.

  File "/Users/ahmedalmaghasilah/Desktop/Blender/Goo/scripts/modules/goo/goo.py", line 568, in make_cell
    bpy.context.object.name = cell.data['name']
AttributeError: 'NoneType' object has no attribute 'name'

it might be the limitation of current running script implementation. But I do not have time to investigate it.

class RunScriptOperator(bpy.types.Operator):
    def execute(self, context):
        ctx = prepare_script_context(self.filepath)
        runpy.run_path(self.filepath, init_globals={"CTX": ctx})
        redraw_all()
        return {"FINISHED"}
