public enum PhysicsComposer.Operation
Remarks
Pass an operation into PhysicsComposer.AddLayer to control how each new layer combines with the layers already added to the PhysicsComposer. adds the shape, keeps only the areas where the new shape and the existing shapes overlap, subtracts the new shape from the existing shapes, and removes overlapping areas but keeps the non-overlapping areas.
