Resources.FindObjectsOfTypeAll

Parameters

Returns

Object[] An array of objects whose class is type or is derived from type.

Description

Returns a list of all objects of Type type.

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);
