Resources.FindObjectsOfTypeAll

Parameters

Returns

Object[] 对象数组，其类为 type 或派生自 type。

Description

返回所有类型为 type 的对象的列表。

This function can return any type of Unity object that is loaded, including game objects, prefabs, materials, meshes, textures, etc. It will also list internal objects. Therefore be careful with the way you handle the returned objects. Contrary to Object.FindObjectsOfType this function will also list disabled objects.

Note: This function is very slow and is not recommended to be used every frame.

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;
    }
}

Description

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。

    // 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<UnityEngine.Object>().Length);
        print("Textures " + Resources.FindObjectsOfTypeAll<Texture>().Length);
        print("AudioClips " + Resources.FindObjectsOfTypeAll<AudioClip>().Length);

            objectsInScene.Add(go);

        return objectsInScene;

Display the stored GameObject names:

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

public class ExampleScript : MonoBehaviour
{
    // Find all of the GameObjects in the Resources folder
    // Add a GameObject called "Player" so at least 1 GameObject will be stored.
    // However, there are nearly twenty GameObjects.

    void Start()
    {
        string s = "";
        GameObject[] gameObjects;
        int count = 0;

        GameObject player = new GameObject("Player");
        gameObjects = Resources.FindObjectsOfTypeAll<GameObject>();

        foreach (GameObject go in gameObjects)
        {
            s = s + go.name;

            if ((count == 4))
            {
                s = s + "\n";
                count = 0;
            }
            else
            {
                s = s + ' ';
                count++;
            }
        }

        Debug.Log(s);

        // Prints:

        //GameObject InternalIdentityTransform torus cube cylinder
