–建構、解構–<

public class ClassA { //建構子 public ClassA() { }

//解構子 ~ClassA() { } }

{ object obj = new object; <= 建構

} <= 解構(之後都用不到時)

–實例，工廠與控制中心–< public class FactoryConsole {

public static event Action OperationAllFactory;
public static event Action StopAllFactory;

Factory factory001 = new Factory();
Factory factory002 = new Factory();
Factory factory003 = new Factory();
Factory factory004 = new Factory();

public void StartAllFactory()
{
    OperationAllFactory.Invoke();
}
public void StopAllFactory()
{
    StopAllFactory.Invoke();
}

}

public class Factory { bool isOperation = true;

public Factory()
{
//在建構時先把事件註冊好
FactoryConsole.OperationAllFactory += StartOperation;
FactoryConsole.StopAllFactory += StopOperation;
}

public void StartOperation()
{
    isOperation = true;
}
public void StopOperation()
{
    isOperation = false;
}

~Factory()
{
    //在解構時取消註冊所有事件(即使可能取消過了)，以避免Invoke event時可能的錯誤
    FactoryConsole.OperationAllFactory -= StartOperation;
    FactoryConsole.StopAllFactory -= StopOperation;
}

}

一些細節 GetSet可以直接添加判斷式 private object obj; public object Obj { get => obj; set { if (value != null) obj = value; } }

transform是 { get; } transform等同於 GetComponent(); 所以每禎調用的話會很吃效能

簡寫if(object != null) { object.Function(); } 可以簡寫成 object?.Function();

如果你無法預期一個Coroutine需要執行多久(禎)，但你需要在他執行完後做某件事，你可以丟一個委派當輸入 IEnumerator WaitRandomSecond(System.Action callback) { float duration = UnityEngine.Random.Range(1f, 3f); yield return new WaitForSeconds(duration); callback?.Invoke(); }

清除event 用迴圈取出已註冊的事件，一個一個取消 foreach(Delegate d in FindClicked.GetInvocationList()) { FindClicked -= (FindClickedHandler)d; } 可以使用 = null 來清除，但不建議
