  4. Extrudes a 2D polygon shape to create a 3D mesh.

  6. <description>
  7. An array of 2D points is extruded to quickly and easily create a variety of 3D meshes. See also [CSGMesh] for using 3D meshes as CSG nodes.
  8. [b]Note:[/b] CSG nodes are intended to be used for level prototyping. Creating CSG nodes has a significant CPU cost compared to creating a [MeshInstance] with a [PrimitiveMesh]. Moving a CSG node within another CSG node also has a significant CPU cost, so it should be avoided during gameplay.

  26. When [member mode] is [constant MODE_PATH], by default, the top half of the [member material] is stretched along the entire length of the extruded shape. If [code]false[/code] the top half of the material is repeated every step of the extrusion.

  36. </member>
  37. <member name="path_local" type="bool" setter="set_path_local" getter="is_path_local">
  38. When [member mode] is [constant MODE_PATH], if [code]true[/code] the [Transform] of the [CSGPolygon] is used as the starting point for the extrusions, not the [Transform] of the [member path_node].
