AnimationNodeBlendSpace1D
=========================

**Inherits:** :ref:`AnimationRootNode<class_AnimationRootNode>` **<** :ref:`AnimationNode<class_AnimationNode>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Blends linearly between two of any number of :ref:`AnimationNode<class_AnimationNode>` of any type placed on a virtual axis.

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

A resource to add to an :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`.

This is a virtual axis on which you can add any type of :ref:`AnimationNode<class_AnimationNode>` using :ref:`add_blend_point<class_AnimationNodeBlendSpace1D_method_add_blend_point>`.

Outputs the linear blend of the two :ref:`AnimationNode<class_AnimationNode>`\ s closest to the node's current value.

You can set the extents of the axis using the :ref:`min_space<class_AnimationNodeBlendSpace1D_property_min_space>` and :ref:`max_space<class_AnimationNodeBlendSpace1D_property_max_space>`.
