如何在特定時間后遍歷每個 object 的對象？

Question

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);
    }
}

這個想法不是阻塞整個編輯器並等待foreach循環完成，而是讓它在第一個項目上循環等待一秒鍾，然后繼續到下一個，依此類推。

現在它讓編輯器窒息，凍結它直到循環結束。

我到目前為止所做的事情還沒有很好地工作：

我為檢查器中的按鈕創建了一個新的編輯器腳本：

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();
        }
    }
}

然后在比較對象中：

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);
            }
        }
    }
}

但它只做一個 object 而不是所有的對象。

Answer 1

StartCoroutine 的行為方式與啟動新線程的方式相同，因此當您調用Compare時，您所做的只是循環遍歷游戲對象並創建事件對象，這些對象在主線程中運行時，不會阻止創建的方法它停止運行，所以最終只有新事件 object 等待指定的時間，而 main 方法繼續循環通過游戲對象的 rest 並創建更多事件對象，它本身沒有調用任何睡眠函數，而是你應該做像這樣的東西：

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;

StartComparing將啟動一個Compare協程，它將 go 遍歷所有對象，因此，首先 object 然后等待指定的waitTime然后第二個StopComparing被調用，以此類推。Compar 完成

測試了代碼，這是它的一個小（字面意思）預覽，您會看到在更改速度后它記錄對象的速度變慢：
