Summary

In this chapter, we learned about the Decorator pattern and its application in creating dynamic power-up systems for games. The Decorator pattern is a structural design pattern that allows us to wrap objects with additional functionalities at runtime without altering their underlying code, as we learned in this chapter. This approach adheres to the open-closed principle, which promotes extending functionality while keeping the original class intact. By applying this pattern, we learned that we can flexibly add or remove features to an object during the game, such as modifying player attributes, including movement speed, jump height, and attack strength when power-ups are collected.

We explored how the Decorator pattern works by wrapping a base object, in this case, the Stats class, with new behaviors through decorator objects. The decorators act as wrappers, allowing us to stack multiple power-ups and apply their effects in different combinations. For instance, when a player...
