本文主要分享從 Unity 2D 小遊戲轉移到 Cocos Creator 上的一些心得。
1. Why？
2. 會遇到什麼問題？
3. 轉移要花多少時間？
4. C# => TypeScript
5. Unity => Cocos
6. 小結
Use Unity.app directly instead of UnityHub.
Insert access database by SQLite.

![[Unity] Performance Test – String Concat](http://blog.ctrlxctrlv.net/wp-content/uploads/2019/07/unity-performance-string-concat-700x290.png "[Unity] Performance Test – String Concat")
Recommended to use string.Concat() or directly use + operator for better performance.
Test times: 10,000,000
1. PlusOperator: 6825
2. Interpolation: 10037
3. StringFormat: 9940
4. StringConcat: 6822
5. StringJoin: 8255
6. StringBuilder: 7157
命名曾經被程式設計師們列為，寫程式時最困難的事
當有用到的 Serialized Fields 需要重新命名時
GameObject 或 ScriptableObject 中的資料會遺失
範例情境
1. 原始設計：private member with public getter
2. 需求變更：private member with public getter & setter
3. 重構問題：將 private member 改為 public member，並移除多餘的 public getter & setter
解決方案
1. 直接使用文字編輯器打開 Prefab 或 ScriptableObject
2. 使用 [FormerlySerializedAs] attribute

![[Unity] Performance Test – String Comparison](http://blog.ctrlxctrlv.net/wp-content/uploads/2017/07/unity-string-comparison-700x290.png "[Unity] Performance Test – String Comparison")
Recommended to use string.Equals() for better performance.
Test times: 10,000,000
1. EqualityOperator: 464
2. StringEquals: 406
3. StringEqualsByIgnoreCase: 13557

使用 Unity Time 下的各種屬性，包含 time、deltaTime、fixedDeltaTime
只有在不同 Frame 才會有值
想要正確測試某個函式的時間，可以採用以下三種方法
值得一提的是，Stopwatch 似乎就是為了做這件事情而存在的
1. DateTime.Now
2. Environment.TickCount
3. System.Diagnostics.Stopwatch
