The only method I could find was to use an operator which seems more like a workaround than a solution.

  • $\begingroup$ Could you clarify? Add a rigid body object to the mesh, or add rigid body properties to the mesh? More information is better, and you are more likely to get an answer. $\endgroup$ – VRM Jan 2 '15 at 20:48
  • $\begingroup$ I meant a rigid body object to an object in the scene, though adding properties to the rigid body would be helpful too $\endgroup$ – hell2o Jan 2 '15 at 22:01

This will add rigid body to the object (add the object to the rigid body group of the scene)


as zeffii pointed this assumes that a rigid_body_world has been created, which is done with bpy.ops.rigidbody.world_add()

  • $\begingroup$ This seems to assume that the rigid body world has been enabled. Which might not be the case until the .ops is used at least once. Else rigidbody_world is None $\endgroup$ – zeffii Mar 13 '15 at 17:43
  • $\begingroup$ @zeffii yes, I'll add that in $\endgroup$ – Chebhou Mar 13 '15 at 17:45

Select an object and make sure no other object is selected (deselect them if that is the case), then run the following script to add a rigid body to the object of your choice.

I found this out by hovering my mouse over the 'Rigid Body' button... the tool tip is 'bpy.ops.rigidbody.objects_add()'

import bpy
bpy.context.scene.objects.active.rigid_body.type=True # Set to False for Passive objects
  • $\begingroup$ In the question I did specify that I wasn't looking for an operator as blender.org/api/blender_python_api_2_73_release/… seems to imply that operators shouldn't be used in scripting with "Blender’s operators are tools for users to access" or at least that was what I thought it implied when reading previously $\endgroup$ – hell2o Jan 12 '15 at 9:26
  • $\begingroup$ So you did. I've done some more searching, but came up with no solution. It appears that via python, the 'rigid_body' component of an 'object' is readonly. (blender.org/api/blender_python_api_2_73_release/…) $\endgroup$ – JohnD Jan 13 '15 at 22:53
