美好的一天，我的 Unity 游戲中有一個腳本，它創建一個列表并將其數字順序隨機化，然后將值傳遞給另一個列表以檢查一些特定屬性，這是代碼：// Use this for initializationprivate List<int> PreList = new List<int>();private List<int> ButtonList = new List<int>();private List<int> UserList = new List<int>();private System.Random Rnd = new System.Random();void Randomizer(){ PreList.Add(1); PreList.Add(2); PreList.Add(3); PreList.Add(4); PreList.Add(5); PreList.Add(6); PreList.Add(7); PreList.Add(8); PreList.Add(9); PreList = PreList.OrderBy(C => Rnd.Next()).ToList(); foreach (int Number in PreList) { Debug.Log(Number); Debug.Log(ButtonList.Count); if (Number == 1) { OneMethod(); } else if (Number == 2) { TwoMethod(); } else if (Number == 3) { ThreeMethod(); } else if (Number == 4) { FourMethod(); } else if (Number == 5) { FiveMethod(); } else if (Number == 6) { SixMethod(); } else if (Number == 7) { SevenMethod(); } else if (Number == 8) { EightMethod(); } else if (Number == 9) { NineMethod(); } }} void OneMethod() { ButtonList.Add(1); GameObject RedButton = GameObject.Find("Red"); //There are 8 methods just like this, but it variates some stuff like the name and the number, all of these add numbers to ButtonList }此時，輸出控制臺只是說 ButtonList 的計數是 9，但是，如果我放一個 if 來檢查它，它永遠不會將值設為 true，就像它不執行方法并且 ifs 永遠不會運行，但是，你知道為什么嗎？

我不確定這是否會解決您的問題，但這是生成隨機順序列表的更好方法：
public class MyClass {
private List<int> PreList = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
private List<int> ButtonList = new List<int>();
private List<int> UserList = new List<int>();
void Randomizer() {
while (PreList.Count > 0 ) {
var idx = UnityEngine.Random.Range(0, PreList.Count); // Randomly select from remaining items
var value = PreList[idx]; // Get item value
PreList.RemoveAt(idx); // Remove item from future options
ButtonList.Add(value); // Add to end of 'randomised' list
}
foreach (var value in ButtonList) {
DoSomethingWith(value);
}
}
void DoSomethingWith(int value) {
switch(value) {
case 1: OneMethod(); break;
case 2: TwoMethod(); break;
case 3: ThreeMethod(); break;
case 4: FourMethod(); break;
case 5: FiveMethod(); break;
case 6: SixMethod(); break;
case 7: SevenMethod(); break;
case 8: EightMethod(); break;
case 9: NineMethod(); break;
}
}
}
編輯：添加示例使用 DoSomething()
