本文介绍了一个Unity游戏开发中使用AssetBundle加载预置物和精灵图集的非IncludeinBuild模式示例。通过IEnumerator协程Start()加载指定路径的资源包，并实例化游戏对象。OnEnable()和OnDisable()方法用于注册和注销SpriteAtlasManager的atlasRequested事件，以实现资源的按需加载。

下面的代码是非Include in Build模式

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.U2D;

public class loadpre : MonoBehaviour {
    
    public string prefabBundle = "preab_late";
    public string saBundle = "atlasab_late";
    
    IEnumerator Start ()
    {
        var loadOp = new WWW("file://" + Application.streamingAssetsPath + "/" + prefabBundle);
        yield return loadOp;

        var prepre = loadOp.assetBundle.LoadAsset<GameObject>("prop_parachute");
        GameObject.Instantiate(prepre);
    }

    void OnEnable()
    {
        SpriteAtlasManager.atlasRequested += RequestLateBindingAtlas;
    }

    void OnDisable()
    {
        SpriteAtlasManager.atlasRequested -= RequestLateBindingAtlas;
    }

    void RequestLateBindingAtlas(string tag, System.Action<SpriteAtlas> action)
    {
        StartCoroutine(LoadFromAssetBundle(tag, action));
    }

    IEnumerator LoadFromAssetBundle(string tag, System.Action<SpriteAtlas> action)
    {
        var loadOp = new WWW("file://" + Application.streamingAssetsPath + "/" + saBundle);
        yield return loadOp;

        var sa = loadOp.assetBundle.LoadAsset<SpriteAtlas>(tag);
        action(sa);
    }
    
}
