:ref:`RefCounted` **<** :ref:`Object` 一组放置在 2D 坐标上的 :ref:`AnimationRootNode`\ ，在三个相邻节点之间交叉淡化。被 :ref:`AnimationTree` 使用。 .. rst-class:: classref-introduction-group 描述 ---- :ref:`AnimationNodeBlendTree` 使用的资源。 \ **AnimationNodeBlendSpace2D** 代表放置 :ref:`AnimationRootNode` 的虚拟 2D 空间。输出的是使用 :ref:`Vector2` 权重对相邻的三个动画进行线性混合的结果。此处的“相邻”指的是构成包含当前值的三角形的三个 :ref:`AnimationRootNode`\ 。 你可以使用 :ref:`add_blend_point()` 向混合空间中添加顶点，将 :ref:`auto_triangles` 设为 ``true`` 可以将其自动三角形化。否则，请使用 :ref:`add_triangle()` 和 :ref:`remove_triangle()` 手动对混合空间进行三角形化。 .. rst-class:: classref-introduction-group 教程
