:tea: All Gang of Four Design Patterns written in Unity C# with many examples. And some Game Programming Patterns written in Unity C#. | 各种设计模式的Unity3D C#版本实现
A Unity3D reference implementation of all 23 Gang of Four patterns plus 9 patterns from the Game Programming Patterns book, with each pattern in its own folder containing structure code, examples, and Unity scenes. It targets Unity/C# developers who want to see classic OOP patterns applied in a game engine context rather than a generic C# console app. Last touched in early 2020.
Each pattern comes with both a bare-bones structural implementation and at least one real-world game example, so you can compare the abstract skeleton against something concrete. The Game Programming Patterns section covers things GoF doesn't — object pool, dirty flag, data locality — which matter more day-to-day in Unity than most of the GoF behavioral patterns. The per-pattern Unity scenes mean you can open one folder, hit Play, and see the pattern running without wiring anything up yourself. Command pattern gets four examples including undo/redo input handling, which is actually the hard case most references skip.
Abandoned since February 2020 — Unity has changed significantly (jobs system, Burst, ECS) and none of that is reflected here, so the patterns for performance-sensitive code (data locality, object pool) are written against the old MonoBehaviour model that the job system is meant to replace. No tests anywhere; the only way to verify an example works is to open it in the Unity Editor, which makes this a read-only reference rather than something you can fork and extend with confidence. The observer pattern example ignores C# events and delegates entirely, implementing a manual subscription list instead — a beginner following it would end up writing worse code than just using `event Action`. The repo also predates Unity's own design pattern guidance, so it has no opinion on scriptable objects or the addressables patterns that Unity developers actually argue about now.
