We already removed it from the online docs with #35132. Currently it can only be "Built-In Types" (Variant types) or "Core" (everything else), which is of limited use. We might also want to consider dropping it from `ClassDB` altogether in Godot 4.0.

|
|
[Mesh] type that provides utility for constructing a surface from arrays.
|
|
</brief_description>
|
|
<description>
|
|
The [ArrayMesh] is used to construct a [Mesh] by specifying the attributes as arrays.
|
|
The most basic example is the creation of a single triangle:
|
|
[codeblock]
|
|
var vertices = PoolVector3Array()
|
|
vertices.push_back(Vector3(0, 1, 0))
|
|
vertices.push_back(Vector3(1, 0, 0))
|
|
vertices.push_back(Vector3(0, 0, 1))
|
|
# Initialize the ArrayMesh.
|
|
var arr_mesh = ArrayMesh.new()
|
|
var arrays = []
|
|
arrays.resize(ArrayMesh.ARRAY_MAX)
|
|
arrays[ArrayMesh.ARRAY_VERTEX] = vertices
|
|
# Create the Mesh.
|
|
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arrays)
|
|
var m = MeshInstance.new()
|
|
m.mesh = arr_mesh
|
|
[/codeblock]
|
|
The [MeshInstance] is ready to be added to the [SceneTree] to be shown.

|
Creates a new surface.
|
|
Surfaces are created to be rendered using a [code]primitive[/code], which may be any of the types defined in [enum Mesh.PrimitiveType]. (As a note, when using indices, it is recommended to only use points, lines or triangles.) [method Mesh.get_surface_count] will become the [code]surf_idx[/code] for this new surface.
|
|
The [code]arrays[/code] argument is an array of arrays. See [enum ArrayType] for the values used in this array. For example, [code]arrays[0][/code] is the array of vertices. That first vertex sub-array is always required; the others are optional. Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data and the index array defines the vertex order. All sub-arrays must have the same length as the vertex array or be empty, except for [constant ARRAY_INDEX] if it is used.
|
|
Adding an index array puts this function into "index mode" where the vertex and other arrays become the sources of data, and the index array defines the order of the vertices.
|
|
Godot uses clockwise winding order for front faces of triangle primitive modes.

<constant name="ARRAY_INDEX" value="8" enum="ArrayType">
|
|
[PoolIntArray] of integers used as indices referencing vertices, colors, normals, tangents, and textures. All of those arrays must have the same number of elements as the vertex array. No index can be beyond the vertex array size. When this index array is present, it puts the function into "index mode," where the index selects the *i*'th vertex, normal, tangent, color, UV, etc. This means if you want to have different normals or colors along an edge, you have to duplicate the vertices.
|
|
For triangles, the index array is interpreted as triples, referring to the vertices of each triangle. For lines, the index array is in pairs indicating the start and end of each line.
