BBMOD_MeshBuilder

A constructor defined in BBMOD_MeshBuilder.gml

new BBMOD_MeshBuilder([_primitiveType])

Description

Allows you to build meshes through code.

Arguments

Name	Type	Description
_primitiveType	`Constant.PrimitiveType`	The primitive type of built meshes. Defaults to `pr_trianglelist`.

Properties

Name	Description
Faces	List of vertex indices that make up a face. First three indices are the first face, next three indices are the second face etc.
PrimitiveType	The primitive type of built meshes.
Vertices	List of mesh vertices.

Methods

Name	Description
add_face	Adds a face to the mesh.
add_vertex	Adds a vertex to the mesh.
build	Builds a mesh from the added vertices and faces.
destroy	Frees memory used by the struct.
make_tangents	Makes tangent and bitangent vectors for added vertices.

Example

Following code shows how you can create a plane mesh using the mesh builder.

var _meshBuilder = new BBMOD_MeshBuilder();
var _vertexFormat = new BBMOD_VertexFormat(true);
var _v1 = new BBMOD_Vertex(_vertexFormat);
_v1.Position = new BBMOD_Vec3(0.0, 0.0, 0.0);
var _v1Ind = _meshBuilder.add_vertex(_v1);
var _v2 = new BBMOD_Vertex(_vertexFormat);
_v2.Position = new BBMOD_Vec3(1.0, 0.0, 0.0);
var _v2Ind = _meshBuilder.add_vertex(_v2);
var _v3 = new BBMOD_Vertex(_vertexFormat);
_v3.Position = new BBMOD_Vec3(1.0, 1.0, 0.0);
var _v3Ind = _meshBuilder.add_vertex(_v3);
var _v4 = new BBMOD_Vertex(_vertexFormat);
_v4.Position = new BBMOD_Vec3(0.0, 1.0, 0.0);
var _v4Ind = _meshBuilder.add_vertex(_v4);
_meshBuilder.add_face(_v1Ind, _v2Ind, _v4Ind);
_meshBuilder.add_face(_v2Ind, _v3Ind, _v4Ind);
var _mesh = _meshBuilder.build();
_meshBuilder = _meshBuilder.destroy();
