Command, Flyweight, Factory, Builder, Strategy and Decorator can often be implemented to fix common code smells – in today's video you'll learn how as we refactor an Enemy Spawner from a naive implementation to a robust, modular and extensible system using game programming patterns.

NOTE: The custom method RandomPointInAnnulus achieves uniform distribution within an annulus by using the square root of a uniformly distributed random value to determine the radius, thus ensuring a uniform distribution of points across the area. This approach takes into account the increasing area with the square of the radius, resulting in a uniform density of points. In contrast, Unity's Random.insideUnitCircle generates points based on a uniform radius distribution, resulting in a higher concentration of points near the center because the larger area is not taken into account at larger radii.
