FastNoiseLite
=============
**继承：** :ref:`Noise<class_Noise>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
使用 FastNoiseLite 库生成噪声。
.. rst-class:: classref-introduction-group
描述
----
该类使用 FastNoiseLite 库生成噪声，该库是多种噪声算法的集合，包括 Cellular、Perlin、Value 等。
大多数生成的噪声值都在 ``[-1, 1]`` 范围内，但并非总是如此。一些蜂窝噪声算法返回高于 ``1`` 的结果。
