 				Copies the viewport to a region of the screen specified by [code]rect[/code]. If [method viewport_set_render_direct_to_screen] is [code]true[/code], then the viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to.
 				For example, you can set the root viewport to not render at all with the following code:
-				[codeblock]
+				FIXME: The method seems to be non-existent.
+				[codeblocks]
+				[gdscript]
 				func _ready():
 				    get_viewport().set_attach_to_screen_rect(Rect2())
 				    $Viewport.set_attach_to_screen_rect(Rect2(0, 0, 600, 600))
-				[/codeblock]
+				[/gdscript]
+				[/codeblocks]
 				Using this can result in significant optimization, especially on lower-end devices. However, it comes at the cost of having to manage your viewports manually. For a further optimization see, [method viewport_set_render_direct_to_screen].

 		The [SurfaceTool] is used to construct a [Mesh] by specifying vertex attributes individually. 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.
