加載方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using UnityEngine.Networking;

public class LoadFromFileExample : MonoBehaviour {

    private string path;
    void Start()
    {
        path = "AssetBundles/kaka.luete";
        //從記憶體中異步加載
        StartCoroutine(LoadFromMemoryAsync());
        //記憶體中同步加載
        LoadFromMemory();
        //本地中異步加載
        StartCoroutine(LoadFromFileAsync());
        //從緩存或伺服器上加載
		StartCoroutine(LoadFromCache());
		//第四種方法，最常用的方法，使用UnityWebRequest加載
		StartCoroutine(LoadFromUnityWebRequest());

    }

講解

上邊呢是使用了四種方法加載，本次使用本地加載方法（最後一種）

首先記得修改路徑為你的本地路徑

然後呢修改你的名字 ，就是你的AB包的名字

完事
