This allows the :ref:`Bone2D` nodes to react to physics thanks to the linked :ref:`PhysicalBone2D` nodes. Experimental. Physical bones may be changed in the future to perform the position update of :ref:`Bone2D` on their own. .. rst-class:: classref-reftable-group Properties ---------- .. table:: :widths: auto +-----------------------+------------------------------------------------------------------------------------------------------------------+-------+ | :ref:`int` | :ref:`physical_bone_chain_length` | ``0`` | +-----------------------+------------------------------------------------------------------------------------------------------------------+-------+ .. rst-class:: classref-reftable-group Methods ------- .. table:: :widths: auto +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | void | :ref:`fetch_physical_bones` **(** **)** | +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | :ref:`NodePath` | :ref:`get_physical_bone_node` **(** :ref:`int` joint_idx **)** |const| | +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | void | :ref:`set_physical_bone_node` **(** :ref:`int` joint_idx, :ref:`NodePath` physicalbone2d_node **)** | +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | void | :ref:`start_simulation` **(** :ref:`StringName[]` bones=[] **)** | +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | void | :ref:`stop_simulation` **(** :ref:`StringName[]` bones=[] **)** | +---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ .. rst-class:: classref-section-separator ---- .. rst-class:: classref-descriptions-group Property Descriptions --------------------- .. _class_SkeletonModification2DPhysicalBones_property_physical_bone_chain_length: .. rst-class:: classref-property :ref:`int` **physical_bone_chain_length** = ``0`` .. rst-class:: classref-property-setget - void **set_physical_bone_chain_length** **(** :ref:`int` value **)** - :ref:`int` **get_physical_bone_chain_length** **(** **)** The number of :ref:`PhysicalBone2D` nodes linked in this modification. .. rst-class:: classref-section-separator ---- .. rst-class:: classref-descriptions-group Method Descriptions ------------------- .. _class_SkeletonModification2DPhysicalBones_method_fetch_physical_bones: .. rst-class:: classref-method void **fetch_physical_bones** **(** **)** Empties the list of :ref:`PhysicalBone2D` nodes and populates it with all :ref:`PhysicalBone2D` nodes that are children of the :ref:`Skeleton2D`. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DPhysicalBones_method_get_physical_bone_node: .. rst-class:: classref-method :ref:`NodePath` **get_physical_bone_node** **(** :ref:`int` joint_idx **)** |const| Returns the :ref:`PhysicalBone2D` node at ``joint_idx``. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DPhysicalBones_method_set_physical_bone_node: .. rst-class:: classref-method void **set_physical_bone_node** **(** :ref:`int` joint_idx, :ref:`NodePath` physicalbone2d_node **)** Sets the :ref:`PhysicalBone2D` node at ``joint_idx``. \ **Note:** This is just the index used for this modification, not the bone index used in the :ref:`Skeleton2D`. .. rst-class:: classref-item-separator ---- .. _class_SkeletonModification2DPhysicalBones_method_start_simulation: .. rst-class:: classref-method void **start_simulation** **(** :ref:`StringName[]` bones=[] **)** Tell the :ref:`PhysicalBone2D` nodes to start simulating and interacting with the physics world.
