C# 如何通过单击Unity中的按钮来激活和停用20个面板阵列中的面板

我正在制作一个儿童教育游戏。 我有20个问题小组。如果回答正确，则会激活一个按钮。如果单击按钮，下一个面板应处于活动状态，最后一个活动面板应处于停用状态。这应该发生在所有20个面板上

代码如下：

public class PanelChanger : MonoBehaviour
{
    public GameObject nextButton;
    public GameObject[] QuestionsPanel;
    public GameObject wellDonePanel;

    // Start is called before the first frame update
    public void Start()
    {

        QuestionsPanel[Random.Range(0, QuestionsPanel.Length)].SetActive(true);
    }

    // Update is called once per frame
    void Update()
    {
   
    }

   ...

在这里，我想放置代码以激活下一个面板并停用活动面板。在这段代码中，我可以设置活动的随机面板，但不能停用当前面板

---

将当前面板存储在字段中

private GameObject currentPanel;

而且总是这样

// If a previous panel exists deactivate it
if(currentPanel) currentPanel.SetActive(false);

// Store the new panel
currentPanel = QuestionsPanel[Random.Range(0, QuestionsPanel.Length)];
// Activate the new panel
currentPanel.SetActive(true);

或者简单地迭代整个数组并执行以下操作

// Get the tendon index
var randomIndex = Random.Range(0, QuestionsPanel.Length);
// Iterate all panels
for(var i = 0; i < QuestionsPanel.Length; i++)
{
    // Set the matching panel active, all others inactive
    QuestionsPanel[i].SetActive(i == randomIndex);
}

非常感谢你的帮助，你正好提出了我要找的东西。非常感谢。

// Get the tendon index
var randomIndex = Random.Range(0, QuestionsPanel.Length);
// Iterate all panels
for(var i = 0; i < QuestionsPanel.Length; i++)
{
    // Set the matching panel active, all others inactive
    QuestionsPanel[i].SetActive(i == randomIndex);
}

using System.Linq;

...

private GameObject [] randomizedQuestions;

private int currentIndex;
private GameObject currentPanel;

private void Start ()
{
    Shuffle ();
    ShowNextQuestion();
}

private void Shuffle()
{
    randomizedQuestions = QuestionPanel.OrderBy(p => Random.value).ToArray();
}

public void ShowNextQuestion ()
{
    if(currentIndex >= randomizedQuestions.Length)
    {
        // Up to you. You can either just stop
        Debug.LogWarning("No more questions available", this);
        return;

        // Or you could just start over 
        Shuffle();
        currentIndex = 0;
    }

    if(currentPanel) currentPanel.SetActive(false);

    currentPanel = randomizedQuestions[currentIndex];

    currentPanel.SetActive(true);

    currentIndex++;      
}
