为监听器创建协程

Question

我的主脚本按 1 对一组球进行排序，我正在调用该脚本，所以当我 click this 按钮时，它将触发排序按钮，它会通过在示例之间等待 1-2 秒来按 1 对 1 排序每次交换。但是，当我单击用于立即触发自动排序的按钮时，这里的协程并没有做它应该做的事情。

这是一组未分类的球。 Here 有没有什么办法解决这一问题？

namespace Assets
{
    public class Trigger : MonoBehaviour
    {
        public Gameobjects _Gameobjects; 
        public Button e_YourButton;
        public void Start()
        {
            Button btn = e_YourButton.GetComponent<Button>();
            for (int k = 0; k < 4; k++)
            {
                btn.onClick.AddListener(_Gameobjects.TaskOnClick);
                btn.onClick.AddListener(() => { _Gameobjects.Click1(); });
                StartCoroutine(Example());    
            }
        }   

        IEnumerator Example()
        {

           yield return new WaitForSeconds(1);
        }
    }
}

Answer 1

您的第二个脚本（Gameobjects 命名顺便说一句非常糟糕）应该如下所示：

// Don't start another sort while the current isn't finished
// Or: stop the current one with StopAllCoroutines()
bool isSorting = false;

public void TaskOnClick()
{
    if(isSorting == false)
    {
        isSorting = true;
        StartCoroutine(PerformInsertionSort());
    }
}

private IEnumerator PerformInsertionSort()
{
    for(int i = 0; i < Balls.Length - 1; i++)
    {      
        if (string.Compare(Balls[i].name, Balls[i+1].name) > 0)                   
        {
            GameObject temp = Balls[i];
            Balls[i] = Balls[i+1];
            Balls[i+1] = temp;

            posA = Balls[i].gameObject.transform.position;
            posB = Balls[i + 1].gameObject.transform.position;
            Balls[i].gameObject.transform.position = posB;
            Balls[i + 1].gameObject.transform.position = posA;

            // If you want to wait only after a switch actually happend,
            // wait here.
        }

        // This is where you need to wait:
        yield return new WaitForSeconds(1f);
    }

    isSorting = false;
}

您排序的数组是脚本的成员，因此将其作为参数传递给脚本内的函数是没有意义的。
