Hi! This was sent as a follow-up to this old mail I sent almost 2 weeks ago. http://web.archiveorange.com/archive/v/1bjALgeMrd68xjNLOS02
Roughly I could now be able to get over the polling problem for using bpy.ops.sculpt.brush_stroke() by implementing it in a simple modal operator class and run it when the View_3D is set to Sculpt Mode. I also have some ideas how to use OperatorStrokeElement to define new property into the scene. Here is the testing script: http://www.pasteall.org/20953/python The script may appear odd that I use mouse coordinates to feed into the sculpting brush. This is just a test trial as I will supply a new set of coordinates from other input source. However, I still failed to match the required input type for the "stroke" parameter. I often encountered such error messages: ==================================================================================== <YOUR BLENDER DIRECTORY>\2.57\scripts\module\bpy\ops.py", line 179, in __call__ ret = op_call(self.idname_py(), None, kw) TypeError: Converting py args to operator properties: SCULPT_OT_brush_stroke.stroke expected a each sequence member to be a dict for an RNA collection, not XXX ==================================================================================== I'm confused to these error remarks and variations... XXX can be ranging from "tuple", "str", "dict" or "OperatorStrokeElement", etc. They seem to relate to how I defined and used the custom property: If I tried to use a CollectionProperty term of OperatorStrokeElement type (defined in register()) OR If I introduced a dict instance to store readings temporarily from CollectionProperty term instead... You can find out the exact errors by commenting and uncommenting some of the python statements. As a whole, it complaint me for supplying the wrong type of parameters to match the required bpy_prop_collection term at all. Honestly, what I should do to create this required [b]bpy_prop_collection[/b] of OperatorStrokeElement type for the "stroke" parameter? Is it possible to access such RNA collection from Blender? (as I'm not sure if they are all read-only). As still being new to Blender Python and the API didn't review everything, I'm totally stuck. Hope this time I provided sufficient materials for people to look into my problem. Look forwards to your kind replies soon.
