Summary

In this chapter, we learned how to implement AI behaviors using the Strategy pattern, which is one of the simplest yet most versatile design patterns. The Strategy pattern allows us to encapsulate algorithms within individual classes, making them interchangeable and enabling dynamic behavior changes at runtime. By decoupling the algorithms from the classes that use them, this pattern offers flexibility and scalability, allowing us to extend and modify behavior without altering the underlying code base. This approach aligns with the principle of composition over inheritance, making it a fundamental tool for building scalable and maintainable game architecture.

We applied the Strategy pattern to enhance the AI of the Bumping Pig enemy in our game, enabling it to attack, fire, pick up, and throw objects based on the current strategy. By doing so, we created a modular and flexible system that allows the AI to adapt its behavior depending on the game’s context. The Strategy...
