-统一--提供反馈提示，无论单击哪一个错误按钮

Question

我是一名教育研究者，为我的博士课程开发了一个游戏。我正在通过教程和论坛来学习。

我有一个小测验面板(即四个按钮-一个正确的答案和三个错误的答案)。

我想知道如何提供反馈提示的顺序，无论哪个错误的按钮被点击。

这些是面板的一些图片和我目前拥有的代码。

 }     

 // Update is called once per frame
 void Update()
 {
    //check the rest of this post 
 }
 }

我所做的是让它发挥作用，就是把每个提示分配给一个错误的答案按钮。但是这个方法对我的研究来说并不有趣，特别是因为第三个提示实际上是给出了答案。因此，如果一个学生点击一个错误的答案，我手动分配了第三个提示，他们会得到答案的银盘，我的数据是糟糕的。=(

只是为了记住：，我需要显示提示1，2和3，无论学生单击哪个错误按钮。

是否有一种更经济有效的方法来管理这些面板游戏对象？

// Update is called once per frame
 void Update()
 {     
         //PPL buttons and answer management
         if (PPLChoiceMade == 1)
         {

             PPLCenterPanel.SetActive(true);

             PPLHint1TextBox.SetActive(true);
             PPLHint2TextBox.SetActive(false);
             PPLHint3TextBox.SetActive(false);

         }

         if (PPLChoiceMade == 2)
         {          

             PPLCenterPanel.SetActive(true);
             PPLHintPic1.SetActive(false);

             PPLWinPic.SetActive(true);

             PPLChoice1.SetActive(false);
             PPLChoice2.SetActive(true);

任何帮助都将不胜感激！(尤其是因为我已经烧掉了无数的神经元，试图自己找出答案.哈哈！)

Answer 1

要回答额外的请求，请创建一个父容器对象，并将所有容器放置在该父容器中，然后以这种方式遍历它们。

public GameObject hintBoxContainer;

private List<GameObject> hintBoxes = new List<GameObject>();

private void Start(){
  for(int i =0; i < hintBoxContainer.transform.childCount; i++){
    hintBoxes.Add(hintBoxContainer.transform.getChild(i).gameObject);
  }
}

private void Update(){
  if(PPLChoiceMade == 1){
    //Since we know the first hintbox is at the index of 0
    for(int i =0; i < hintBoxes.Count; i++){
      if(i == 0){
        hintBox[i].SetActive(true);
      }else{
        hintBox[i].SetActive(false);
      }
    }
  }
}

作为额外的注意

您应该创建一个单独的函数来初始化列表，这样就不会拥挤您的开始函数，并将更新中的内容分解为函数，从而保持代码的整洁和模块化。记住，要花一些时间来优化，并记住优化和模块化设计技术--在我的早期，许多项目因快速设计系统而不是“正确”而分崩离析:)

Answer 2

让我们来看看这个伪码

if student clicks wrong
    Increment the number of times they have given wrong answers by 1
    What number of incorrect answers have they given?
        if 1 then display hint 1
        if 2 then display hint 2
        if 3 then display hint 3
    Allow them to answer again

考虑到这个伪代码，您需要一些东西：

1. 记录错误答案数量的计数器 public int numberOfWrongAnswers = 0;
2. 为了给出线索的数组(或列表) public string[] hints;
3. 包含对按钮的引用的数组。 public GameObject[] answerButtons;
4. 确定按下哪个按钮的通用方法。 public void PPLChoiceOption(int selection)

从这个开始，我会让你的方法像这样

public void PPLChoiceOption(int selection)
{
    buttons[selection].GetComponent<Button>().interactable = false;
    PPLTextBox.GetComponent<Text>().text = hints[numberOfWrongAnswers - 1];
    showRandomHintImage();
    PPLChoiceMade = selection;
}

请确保将按钮上的引用更改为指向此方法，并在参数中为第一个按钮设置一个0，为下一个按钮设置一个参数，等等。
