SpringBoneCollision3D
=====================

**Inherits:** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`SpringBoneCollisionCapsule3D<class_SpringBoneCollisionCapsule3D>`, :ref:`SpringBoneCollisionPlane3D<class_SpringBoneCollisionPlane3D>`, :ref:`SpringBoneCollisionSphere3D<class_SpringBoneCollisionSphere3D>`

A base class of the collision that interacts with :ref:`SpringBoneSimulator3D<class_SpringBoneSimulator3D>`.

.. rst-class:: classref-introduction-group

Description
-----------

A collision can be a child of :ref:`SpringBoneSimulator3D<class_SpringBoneSimulator3D>`. If it is not a child of :ref:`SpringBoneSimulator3D<class_SpringBoneSimulator3D>`, it has no effect.

The colliding and sliding are done in the :ref:`SpringBoneSimulator3D<class_SpringBoneSimulator3D>`'s modification process in order of its collision list which is set by :ref:`SpringBoneSimulator3D.set_collision_path()<class_SpringBoneSimulator3D_method_set_collision_path>`. If :ref:`SpringBoneSimulator3D.are_all_child_collisions_enabled()<class_SpringBoneSimulator3D_method_are_all_child_collisions_enabled>` is ``true``, the order matches :ref:`SceneTree<class_SceneTree>`.

If :ref:`bone<class_SpringBoneCollision3D_property_bone>` is set, it synchronizes with the bone pose of the ancestor :ref:`Skeleton3D<class_Skeleton3D>`, which is done in before the :ref:`SpringBoneSimulator3D<class_SpringBoneSimulator3D>`'s modification process as the pre-process.

\ **Warning:** A scaled **SpringBoneCollision3D** will likely not behave as expected. Make sure that the parent :ref:`Skeleton3D<class_Skeleton3D>` and its bones are not scaled.
