.. _class_ArrayMesh:
ArrayMesh
=========
**继承：** :ref:`Mesh<class_Mesh>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
:ref:`Mesh<class_Mesh>` 网格类型，提供了用于从数组构造表面的工具。
.. rst-class:: classref-introduction-group
描述
----
**ArrayMesh** 是用来构造 :ref:`Mesh<class_Mesh>` 的，其属性指定为数组。
最基本的例子是创建单个三角形：
.. tabs::
.. code-tab:: gdscript
var vertices = PackedVector3Array()
vertices.push_back(Vector3(0, 1, 0))
vertices.push_back(Vector3(1, 0, 0))
vertices.push_back(Vector3(0, 0, 1))
# 初始化 ArrayMesh。
var arr_mesh = ArrayMesh.new()
var arrays = []
arrays.resize(Mesh.ARRAY_MAX)
arrays[Mesh.ARRAY_VERTEX] = vertices
# 创建 Mesh。
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arrays)
var m = MeshInstance3D.new()
m.mesh = arr_mesh
.. code-tab:: csharp
Vector3[] vertices =
[
new Vector3(0, 1, 0),
new Vector3(1, 0, 0),
new Vector3(0, 0, 1),
];
// 初始化 ArrayMesh。
var arrMesh = new ArrayMesh();
Godot.Collections.Array arrays = [];
arrays.Resize((int)Mesh.ArrayType.Max);
arrays[(int)Mesh.ArrayType.Vertex] = vertices;
// 创建 Mesh。
arrMesh.AddSurfaceFromArrays(Mesh.PrimitiveType.Triangles, arrays);
var m = new MeshInstance3D();
m.Mesh = arrMesh;
这个 :ref:`MeshInstance3D<class_MeshInstance3D>` 就可以添加到要显示的 :ref:`SceneTree<class_SceneTree>` 中了。
程序几何体生成请参阅 :ref:`ImmediateMesh<class_ImmediateMesh>`\ 、\ :ref:`MeshDataTool<class_MeshDataTool>`\ 、\ :ref:`SurfaceTool<class_SurfaceTool>`\ 。
\ **注意：**\ Godot 对三角形图元模式的正面使用顺时针\ `环绕顺序 <https://learnopengl-cn.github.io/04%20Advanced%20OpenGL/04%20Face%20culling/>`__\ 。

创建一个新的表面。\ :ref:`Mesh.get_surface_count()<class_Mesh_method_get_surface_count>` 将成为这个新表面的 ``surf_idx``\ 。
创建表面以使用 ``primitive`` 进行渲染，它可以是 :ref:`PrimitiveType<enum_Mesh_PrimitiveType>` 中定义的任何值。
\ ``arrays`` 参数是数组的数组。每个 :ref:`Mesh.ARRAY_MAX<class_Mesh_constant_ARRAY_MAX>` 元素都包含一个数组，其中包含此表面的一些网格数据，如 :ref:`ArrayType<enum_Mesh_ArrayType>` 的相应成员所描述的一样；如果它未被使用，则为 ``null``\ 。例如，\ ``arrays[0]`` 是顶点数组。始终需要第一个顶点子数组；其他的是可选的。添加索引数组会将此表面置于“索引模式”，其中顶点和其他数组成为数据源，索引数组定义顶点顺序。所有子数组的长度必须与顶点数组的长度相同（或者是顶点数组长度的精确倍数，当子数组的多个元素对应于单个顶点时）；或者为空，如果使用了 :ref:`Mesh.ARRAY_INDEX<class_Mesh_constant_ARRAY_INDEX>` 则除外。
\ ``blend_shapes`` 参数是每个混合形状的顶点数据数组。 每个元素都是与 ``arrays`` 具有相同结构的数组，但是 :ref:`Mesh.ARRAY_VERTEX<class_Mesh_constant_ARRAY_VERTEX>`\ 、\ :ref:`Mesh.ARRAY_NORMAL<class_Mesh_constant_ARRAY_NORMAL>` 和 :ref:`Mesh.ARRAY_TANGENT<class_Mesh_constant_ARRAY_TANGENT>` 这些条目，当且仅当在 ``arrays`` 被设置且所有其他条目都是 ``null`` 时，会被设置。
\ ``lods`` 参数是一个带有 :ref:`float<class_float>` 键和 :ref:`PackedInt32Array<class_PackedInt32Array>` 值的字典。字典中的每个条目代表了表面的一个 LOD 级别，其中值是用于 LOD 级别的 :ref:`Mesh.ARRAY_INDEX<class_Mesh_constant_ARRAY_INDEX>` 数组，键大致与使用 LOD 统计信息的距离成正比。即，增加 LOD 的关键点也会增加在使用 LOD 之前对象必须与相机的距离。
\ ``flags`` 参数是根据需要按位或的：\ :ref:`ArrayCustomFormat<enum_Mesh_ArrayCustomFormat>` 的一个值左移 ``ARRAY_FORMAT_CUSTOMn_SHIFT``\ ，用于每个正在使用的自定义通道，\ :ref:`Mesh.ARRAY_FLAG_USE_DYNAMIC_UPDATE<class_Mesh_constant_ARRAY_FLAG_USE_DYNAMIC_UPDATE>`\ 、\ :ref:`Mesh.ARRAY_FLAG_USE_8_BONE_WEIGHTS<class_Mesh_constant_ARRAY_FLAG_USE_8_BONE_WEIGHTS>` 或 :ref:`Mesh.ARRAY_FLAG_USES_EMPTY_VERTEX_ARRAY<class_Mesh_constant_ARRAY_FLAG_USES_EMPTY_VERTEX_ARRAY>`\ 。
\ **注意：**\ 使用索引时，建议只使用点、线或三角形。
