Node that represents a 3D collision polygon, given by the thickening of a 2D polygon in the local XY plane along the local Z axis.
Provides a 3D collision polygon to a [CollisionObject3D] parent, by thickening a 2D (convex or concave) polygon in the local XY plane along the local Z axis. The 2D polygon in the local XY plane can be drawn in the editor or specified by a list of vertices. That 2D polygon is thickened evenly in the local Z and -Z directions. This node has the same effect as several [ConvexPolygonShape3D] nodes, created by thickening the 2D convex polygons in the convex decomposition of the given 2D polygon (but without the overhead of multiple nodes). [b]Warning:[/b] A non-uniformly scaled CollisionPolygon3D node will probably not function as expected. Please make sure to keep its scale uniform (i.e. the same on all axes), and change its [member polygon]'s vertices instead.
- Length that the resulting collision extends in either direction perpendicular to its 2D polygon.
- If [code]true[/code], no collision will be produced.
- The collision margin for the generated [Shape3D]. See [member Shape3D.margin] for more details.
- Array of vertices which define the 2D polygon in the local XY plane. [b]Note:[/b] The returned value is a copy of the original. Methods which mutate the size or properties of the return value will not impact the original polygon. To change properties of the polygon, assign it to a temporary variable and make changes before reassigning the [code]polygon[/code] member.
