A set of :ref:`AnimationRootNode<class_AnimationRootNode>`\ s placed on 2D coordinates, crossfading between the three adjacent ones. Used by :ref:`AnimationTree<class_AnimationTree>`.
.. rst-class:: classref-introduction-group
Description
-----------
A resource used by :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`.
\ **AnimationNodeBlendSpace2D** represents a virtual 2D space on which :ref:`AnimationRootNode<class_AnimationRootNode>`\ s are placed. Outputs the linear blend of the three adjacent animations using a :ref:`Vector2<class_Vector2>` weight. Adjacent in this context means the three :ref:`AnimationRootNode<class_AnimationRootNode>`\ s making up the triangle that contains the current value.
You can add vertices to the blend space with :ref:`add_blend_point()<class_AnimationNodeBlendSpace2D_method_add_blend_point>` and automatically triangulate it by setting :ref:`auto_triangles<class_AnimationNodeBlendSpace2D_property_auto_triangles>` to ``true``. Otherwise, use :ref:`add_triangle()<class_AnimationNodeBlendSpace2D_method_add_triangle>` and :ref:`remove_triangle()<class_AnimationNodeBlendSpace2D_method_remove_triangle>` to triangulate the blend space by hand.
