public class Resetscr : MonoBehaviour
{
    

    public List<GameInstance> quizInstances;
    // Start is called before the first frame update
    void awake()
    {
        quizInstances[0].Score = 0;


    }

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

我做了一个问答游戏，并且有一个得分面板，得分和游戏实例。（每个测试都有自己的得分面板，得分和游戏实例。）

我需要一个按钮脚本，单击该脚本可以将当前的测试和分数面板重置为0。

要执行此操作，我应该在脚本中写些什么（分数面板和当前测试将得分的数据从一个场景传输到另一个场景，并且我需要在单击该按钮时擦除该数据）。

我应该为每个游戏实例使用按钮脚本还是有使其通用的方法？

您需要提供更多详细信息。这种方法看起来有些问题。

  button.onClick.AddListener(() => { GameInstance1.Score++; });

因为没有检查答案是对还是错。它将继续增加分数。

您可以通过在整个游戏中使用一个Canvas来解决问题，而不破坏Canvas和gameobject使用以下按钮保持回调：

 DontDestroyOnLoad(gameObject);

现在，您需要在该脚本中保留按钮的“ Refreence”（而不是所有Score1实例），以便每个Score1实例可以在需要时添加侦听器和删除侦听器。

现在，在每个Score1实例的开始，您可以订阅Button侦听器并删除旧的侦听器。

 private ButtoncallbackHandler buttoncallback;

 void Start ()
 {
  buttoncallback= GameObject.FindObjectOfType<ButtoncallbackHandler >();
  if(buttoncallback)
 {
    buttoncallback.ScoreButton.onClick.AddListener(() => AnswerValidity());
    buttoncallback.ResetButton.onClick.AddListener(() => OnResetClick());
 }
 }

 void AnswerValidity()
 {
  if(answerisCorrect)
  {

   GameInstance1.Score++;

  }
  else
  {
  ///Wrong Answer Logic.
  }

   // Update your Text Box here
   UpdateTextBox();
 }
 void OnResetClick()
 {

  // Do what you want to do in reset
  UpdateTextBox();

 }

类似地实现ResetButton，您可以重置当前Instacne得分，或者所有得分取决于您，在整个游戏中保留单个文本框。

如何独立重设测验分数？
