obj is a object. If I want to add a driver for its scale X, I can do
d = obj.driver_add("scale", 0).driver
obj has the custom property
var, the following
d = obj.driver_add("var").driver
gives an error:
Traceback (most recent call last): File "<blender_console>", line 1, in <module> TypeError: bpy_struct.driver_add(): property "var" not found
How do I add a driver in this case?
