Unity3D LuaBundleLoader(基于cslua)

说明：异步加载lua的bundle，会优先加载cache目录下bundle(一般更新的资源都在cache下)

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

public class LuaBundleLoader : MonoBehaviour {

	public delegate void DelegateLoading(int idx, int total, string bundleName, string path);
	public delegate void DelegateLoadOver();

	//正在加载中回掉
	public DelegateLoading OnLoading;

	//加载完成回掉
	public DelegateLoadOver OnLoadOver;

	//总共要加载的bundle个数
	private int mTotalBundleCount = 0;

	//当前已加载的bundle个数
	private int mBundleCount = 0;

#if UNITY_5

#else
	public void LoadBundle(string dir, List<string> bundleList)
	{

	}
#endif
	 IEnumerator CoLoadBundle(string name, string path)
	{
		using (WWW www = new WWW(path))
		{
			if (www == null)
			{

		}
#else
        list = bundleList;
#endif
		mTotalBundleCount = list.Count;

		for (int i = 0; i < list.Count; i++)

	IEnumerator CheckLoadFinish()

}

　　

使用代码

var loader = GetComponent<LuaBundleLoader>();
			if (null == loader)
			{
				loader = gameObject.AddComponent<LuaBundleLoader>();
			}

			loader.OnLoading = (idx, total, bundleName, path) =>
			{
				Debug.Log(path+"    ok");
			};

			loader.OnLoadOver = OnBundleLoadOver;

			loader.LoadBundle(LuaConst.osDir, LuaConst.osDir);
