A set of :ref:`AnimationRootNode<class_AnimationRootNode>`\ s placed on a virtual axis, crossfading between the two adjacent ones. Used by :ref:`AnimationTree<class_AnimationTree>`.

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

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

A resource used by :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`.

\ **AnimationNodeBlendSpace1D** represents a virtual axis on which any type of :ref:`AnimationRootNode<class_AnimationRootNode>`\ s can be added using :ref:`add_blend_point<class_AnimationNodeBlendSpace1D_method_add_blend_point>`. Outputs the linear blend of the two :ref:`AnimationRootNode<class_AnimationRootNode>`\ s adjacent to the current value.

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