Summary

In this chapter, we explored the four foundational pillars of OOP: abstraction, encapsulation, inheritance, and polymorphism. We illustrated their application through the development of a LootCrate class in a game project. Abstraction was highlighted as the essential process of simplifying complex systems, enabling us to focus on the relevant aspects of a class while hiding unnecessary details. By abstracting a new LootCrate class, we identified its main features and behaviors, such as the ability to drop items with a specified drop rate. This helps in making the game more engaging for players. This abstraction clarified not only the class’s purpose but also how it should interact with other parts of the game, providing a clear roadmap for its implementation.

Following abstraction, we talked about encapsulation, which protects the internal state of objects and ensures that only necessary interfaces are exposed to other parts of the application. This principle was...
