Resources.FindObjectsOfTypeAll

参数

返回

Object[] 对象数组，其类为 type 或派生自 type。

描述

返回所有类型为 type 的对象的列表。

此函数可以返回已加载的任何类型的 Unity 对象，包括游戏对象、预制件、材质、网格、纹理等。此函数还将列出内部对象。因此请小心处理返回的对象。 与 Object.FindObjectsOfType 不同的是，此函数还将列出禁用的对象。

**注意：**该函数的运行速度非常缓慢，不建议在每帧中使用。

using UnityEngine;
using System.Collections;

public class ExampleScript : MonoBehaviour
{
    // This script displays the number of allocated Unity objects by type.
    // This is useful for finding leaks. Knowing the type of object
    // (mesh, texture, sound clip, game object) that is getting leaked is
    // the first step. You could then print the names of all leaked assets of that type.

    void Start()
    {
        print("All " + Resources.FindObjectsOfTypeAll(typeof(UnityEngine.Object)).Length);
        print("Textures " + Resources.FindObjectsOfTypeAll(typeof(Texture)).Length);
        print("AudioClips " + Resources.FindObjectsOfTypeAll(typeof(AudioClip)).Length);
        print("Meshes " + Resources.FindObjectsOfTypeAll(typeof(Mesh)).Length);
        print("Materials " + Resources.FindObjectsOfTypeAll(typeof(Material)).Length);
        print("GameObjects " + Resources.FindObjectsOfTypeAll(typeof(GameObject)).Length);
        print("Components " + Resources.FindObjectsOfTypeAll(typeof(Component)).Length);
    }
}

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

public class ExampleScript : MonoBehaviour
{
    // This script finds all the objects in Scene, excluding Prefabs:

    List<GameObject> GetAllObjectsInScene()
    {
        List<GameObject> objectsInScene = new List<GameObject>();

        foreach (GameObject go in Resources.FindObjectsOfTypeAll(typeof(GameObject)) as GameObject[])
        {
            if (go.hideFlags == HideFlags.NotEditable || go.hideFlags == HideFlags.HideAndDontSave)
                continue;

            if (!EditorUtility.IsPersistent(go.transform.root.gameObject))
                continue;

            objectsInScene.Add(go);
        }

        return objectsInScene;
    }
}

描述

返回所有类型为 T 的对象的列表。

该函数可以返回任何类型的已加载的 Unity 对象，包括游戏对象、预制件、材质、网格、纹理等。此外，它还会列出内部内容，因此在处理返回的对象时要格外 小心。 与 Object.FindObjectsOfType 相反，该函数还会列出禁用的对象。

请注意，该函数的运行速度非常缓慢，不建议在每帧中使用。
