using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using UnityEditor;
using UnityEngine;

public class CompareObjects : MonoBehaviour
{
    public float waitTime;

    private GameObject[] allObjects;

    public void Compare()
    {
        allObjects = FindObjectsOfType<GameObject>();

        foreach (GameObject go in allObjects)
        {
            Debug.Log(go.name + " >>>>> " + go.scene.name + " >>>>> is active object");
            StartCoroutine(Comparing());
        }
    }

    IEnumerator Comparing()
    {
        yield return new WaitForSeconds(waitTime);
    }
}

我们的想法不是阻塞整个编辑器并等待foreach循环结束，而是让它在第一个项目上循环等待一秒钟，然后继续下一个项目，依此类推。

现在的情况是，它会阻塞编辑器，冻结它，直到循环结束。

到目前为止，我所做的并不是很好：

我为检查器中的一个按钮创建了一个新的编辑器脚本：

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(CompareObjects))]
public class CompareObjectsButton : Editor
{
    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();

        CompareObjects myTarget = (CompareObjects)target;

        if (GUILayout.Button("Compare Objects"))
        {
            myTarget.StartComparing();
        }
    }
}

然后在比较对象中：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using UnityEditor;
using UnityEngine;

public class CompareObjects : MonoBehaviour
{
    public float waitTime;

    private Coroutine comparer;
    private GameObject[] allObjects;

    public void StartComparing()
    {
        if (comparer == null)
        {
            comparer = StartCoroutine(Compare());
        }
    }

    public void StopComparing()
    {
        if (comparer != null)
        {
            StopCoroutine(comparer);

            comparer = null;
        }
    }

    IEnumerator Compare()
    {
        while (true)
        {
            allObjects = FindObjectsOfType<GameObject>();

            foreach (GameObject go in allObjects)
            {
                Debug.Log(go.name + " >>>>> " + go.scene.name + " >>>>> is active object");

                yield return new WaitForSeconds(waitTime);
            }
        }
    }
}

但是它只做一个对象，而不是所有的对象。

StartCoroutine的行为方式与启动新线程的方式相同，所以当您调用Compare时，您所做的就是循环访问游戏对象并创建事件对象，而这些对象在主线程中运行时，不会阻止创建它的方法运行，所以最终只有新的事件对象等待指定的时间，而main方法继续循环访问其余的游戏对象并创建更多的事件对象，sins它本身并没有调用任何睡眠函数，相反，您应该这样做：

public void StartComparing()
{
    if (comparer == null)
    {
        comparer = StartCoroutine(Compare());
    }
}

public void StopComparing()
{
    if (comparer != null)
    {
        StopCoroutine(comparer);

        comparer = null;
    }
}

IEnumerator Compare()
{
    while (true)
    {
        allObjects = FindObjectsOfType<GameObject>();

        foreach (GameObject go in allObjects)
        {
            Debug.Log(go.name + " >>>>> " + go.scene.name + " >>>>> is active object");

            yield return new WaitForSeconds(waitTime);
        }
    }
}

private Coroutine comparer;

private GameObject[] allObjects;

public float waitTime;
