Used by :ref:`AnimationTree`. .. rst-class:: classref-introduction-group Description ----------- A resource used by :ref:`AnimationNodeBlendTree`. \ :ref:`AnimationNodeBlendSpace1D` represents a virtual 2D space on which :ref:`AnimationRootNode`\ s are placed. Outputs the linear blend of the three adjacent animations using a :ref:`Vector2` weight. Adjacent in this context means the three :ref:`AnimationRootNode`\ s making up the triangle that contains the current value. You can add vertices to the blend space with :ref:`add_blend_point` and automatically triangulate it by setting :ref:`auto_triangles` to ``true``. Otherwise, use :ref:`add_triangle` and :ref:`remove_triangle` to triangulate the blend space by hand. .. rst-class:: classref-introduction-group Tutorials --------- - :doc:`Using AnimationTree
