bpy.ops.rigidbody.object_add(type='ACTIVE')

Add active object as Rigid Body

Parameters:type (enum in ['ACTIVE', 'PASSIVE'], (optional)) –

Rigid Body Type

Copy Rigid Body settings from active object to selected

File:startup/bl_operators/rigidbody.py:61
bpy.ops.rigidbody.objects_add(type='ACTIVE')

Add selected objects as Rigid Bodies

Parameters:type (enum in ['ACTIVE', 'PASSIVE'], (optional)) –

Rigid Body Type

  • ACTIVE Active, Object is directly controlled by simulation results.
