It can be used to construct a [Mesh] from a script. All properties except indices need to be added before calling [method add_vertex]. For example, to add vertex colors and UVs: - [codeblock] + [codeblocks] + [gdscript] var st = SurfaceTool.new() st.begin(Mesh.PRIMITIVE_TRIANGLES) st.set_color(Color(1, 0, 0)) st.set_uv(Vector2(0, 0)) st.set_vertex(Vector3(0, 0, 0)) - [/codeblock] + [/gdscript] + [csharp] + var st = new SurfaceTool(); + st.Begin(Mesh.PrimitiveType.Triangles); + st.SetColor(new Color(1, 0, 0)); + st.SetUv(new Vector2(0, 0)); + st.SetVertex(new Vector3(0, 0, 0)); + [/csharp] + [/codeblocks] The above [SurfaceTool] now contains one vertex of a triangle which has a UV coordinate and a specified [Color]. If another vertex were added without calling [method set_uv] or [method set_color], then the last values would be used. Vertex attributes must be passed [b]before[/b] calling [method add_vertex]. Failure to do so will result in an error when committing the vertex information to a mesh. Additionally, the attributes used before the first vertex is added determine the format of the mesh. For example, if you only add UVs to the first vertex, you cannot add color to any of the subsequent vertices. @@ -155,8 +164,8 @@ <argument index="0" name="flip" type="bool" default="false"> </argument> <description> - Generates normals from vertices so you do not have to do it manually.
