6 Data Structures in Unity – Arrays, Lists, Dictionaries, HashSets, and Game Logic

Building on the foundational knowledge acquired in Chapter 5, where we explored the vast capabilities of Unity’s API in enhancing game functionality through physics simulations, scene management, and environmental interactions, Chapter 6 delves deeper into the core of game development—data management. This chapter transitions from the dynamic world of game physics and API interactions to the structured realm of data handling, introducing essential data structures such as arrays, Lists, Dictionaries, and HashSets. Here, we’ll uncover how to effectively organize and manipulate game data, from managing collections of game objects to implementing complex inventory ...
