A constructor defined in BBMOD_MeshBuilder.gml
Implements BBMOD_IDestructible
new BBMOD_MeshBuilder([_primitiveType])Allows you to build meshes through code.
| Name | Type | Description |
|---|---|---|
| _primitiveType | Constant.PrimitiveType |
The primitive type of built meshes. Defaults to pr_trianglelist. |
| 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. |
| 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. |
Following code shows how you can create a plane mesh using the mesh builder.
