class bpy.types.Constraint(bpy_struct)

Constraint modifying the transformation of objects and bones

active

Constraint is the one being edited

Type :boolean, default False
error_location

Amount of residual error in Blender space unit for constraints that work on position

Type :float in [-inf, inf], default 0.0, (readonly)
error_rotation

Amount of residual error in radiant for constraints that work on orientation

Type :float in [-inf, inf], default 0.0, (readonly)
influence

Amount of influence constraint will have on the final solution

Type :float in [0, 1], default 0.0
is_proxy_local

Constraint was added in this proxy instance (i.e. did not belong to source Armature)

Type :boolean, default False
is_valid

Constraint has valid settings and can be evaluated

Type :boolean, default False, (readonly)
mute

Enable/Disable Constraint

Type :boolean, default False
name

Constraint name

Type :string, default “”, (never None)
owner_space

Space that owner is evaluated in

  • WORLD World Space, The constraint is applied relative to the world coordinate system.
  • POSE Pose Space, The constraint is applied in Pose Space, the object transformation is ignored.
  • LOCAL_WITH_PARENT Local With Parent, The constraint is applied relative to the local coordinate system of the object, with the parent transformation added.
  • LOCAL Local Space, The constraint is applied relative to the local coordinate sytem of the object.
Type :enum in [‘WORLD’, ‘POSE’, ‘LOCAL_WITH_PARENT’, ‘LOCAL’], default ‘WORLD’
show_expanded

Constraint’s panel is expanded in UI

Type :boolean, default False
target_space

Space that target is evaluated in

  • WORLD World Space, The transformation of the target is evaluated relative to the world coordinate system.
  • POSE Pose Space, The transformation of the target is only evaluated in the Pose Space, the target armature object transformation is ignored.
  • LOCAL_WITH_PARENT Local With Parent, The transformation of the target bone is evaluated relative its local coordinate system, with the parent transformation added.
  • LOCAL Local Space, The transformation of the target is evaluated relative to its local coordinate system.
Type :enum in [‘WORLD’, ‘POSE’, ‘LOCAL_WITH_PARENT’, ‘LOCAL’], default ‘WORLD’
