I am trying to build up a scene using python to copy objects and their drivers. The object to copy is a simple cube which has the Custom Property prop and a driver for its x-location. The driver consists of a Scripted Expression which references to the variable var, which is just the Single Property prop of the cube. So when I change the value of the Custom Property prop of the cube, I change its x-location.
To copy this cube, I wrote the following python script:
import bpy def main(): scn = bpy.context.scene cube = bpy.data.scenes['Scene'].objects['Cube'] copy_loc_x = 2 copy_obj(scn, cube, copy_loc_x) def copy_obj(scn, obj, prop): # copy object and set a custom property copy = obj.copy() copy.data = obj.data.copy() copy['prop'] = prop scn.objects.link(copy) if __name__ == '__main__': main()
This works perfectly to copy the object and set a new property for the copy, but the copy remains at the same x-location as the original cube. The reason for this is that the variable var of the copy still references to the Custom Property prop of the original cube.
How do I copy the cube, so that its driver variable is automatically referenced to its own Custom Property, just as Shift-D would do? Or, if this is not possible, how do I set the ID-block of a driver variable using python?
