Implementation Notes

• Design patterns used include:
  • Singleton - CONFIG, CONSTANT, Audio etc
  • Strategy - Powerups apply different strategy to render() and update() in Playing state
  • State - Game is state machine. Avoid if else as much as possible
  • Null Object - NullBall to avoid null checking on balls
  • Decorator - render() has decorators applied to draw fps, heart and score, and powerup timeleft
• At one point, the game had memory leaks where RAM usage increases as the player progresses the level. The reason was due to dangling reference to Playing state when implementing Strategy pattern via types.Methodtype(). This causes the garbage collector to unable to free the memory of the Playing state. Problem is fixed once I changed the implementation of Strategy pattern. Lesson: Be careful when implementing strategy via types.MethodType() or __get__ magic method. It may end up in cyclic reference if you are not careful.
