  9. **Inherited By:** :ref:`AnimationNodeAdd2<class_AnimationNodeAdd2>`, :ref:`AnimationNodeAdd3<class_AnimationNodeAdd3>`, :ref:`AnimationNodeBlend2<class_AnimationNodeBlend2>`, :ref:`AnimationNodeBlend3<class_AnimationNodeBlend3>`, :ref:`AnimationNodeOneShot<class_AnimationNodeOneShot>`, :ref:`AnimationNodeOutput<class_AnimationNodeOutput>`, :ref:`AnimationNodeTimeScale<class_AnimationNodeTimeScale>`, :ref:`AnimationNodeTimeSeek<class_AnimationNodeTimeSeek>`, :ref:`AnimationNodeTransition<class_AnimationNodeTransition>`, :ref:`AnimationRootNode<class_AnimationRootNode>`
  10. Base resource for :ref:`AnimationTree<class_AnimationTree>` nodes.
  11. Description
  12. -----------
  13. Base resource for :ref:`AnimationTree<class_AnimationTree>` nodes. In general, it's not used directly, but you can create custom ones with custom blending formulas.
  14. Inherit this when creating nodes mainly for use in :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`, otherwise :ref:`AnimationRootNode<class_AnimationRootNode>` should be used instead.

  151. Here, call the :ref:`blend_input<class_AnimationNode_method_blend_input>`, :ref:`blend_node<class_AnimationNode_method_blend_node>` or :ref:`blend_animation<class_AnimationNode_method_blend_animation>` functions.
  152. You can also use :ref:`get_parameter<class_AnimationNode_method_get_parameter>` and :ref:`set_parameter<class_AnimationNode_method_set_parameter>` to modify local memory.
  153. This function returns the time left for the current animation to finish (if unsure, just pass the value from the main blend being called).
