xLua | xLua Framework | 2 加载

0. 基础

0.1 不同加载模式 测试用

编辑器模式；打包模式；更新模式

public enum GameMode {     EditorMode,     PackageBundle,     UpdateMode, }

0.2 加载资源步骤与接口

     private void LoadAsset(string assetName, Action<Object> action) {     if (AppConst.GameMode == GameMode.EditorMode)     { #if UNITY_EDITOR         EditorLoadAsset(assetName, action); #else         Debug.LogError("Editor mode is not supported in the built version."); #endif     }     else     {         StartCoroutine(LoadBundleAsync(assetName, action));     } }

0.3 解析版本文件

/// <summary> /// 解析版本文件 /// </summary> public void ParseVersionFile() {     //版本文件路径     string url = Path.Combine(PathUtil.BundleResourcePath, AppConst.FileListName);     string[] data = File.ReadAllLines(url);      //解析文件信息     for (int i = 0; i < data.Length; i++)     {         string[] info = data[i].Split('|');          BundleInfo bundleinfo = new BundleInfo()         {             AssetsName = info[0],             BundleName = info[1]         };          //list特性：本质是数组但可动态扩容         bundleinfo.Dependences = new List<string>(info.Length - 2);         for (int j = 2; j < info.Length; j++)         {             bundleinfo.Dependences.Add(info[j]);         }         m_BundleInfos.Add(bundleinfo.AssetsName, bundleinfo);     } }

1. 打包模式加载资源

递归异步加载资源：
根据资源的依赖关系递归加载所有需要的资源包，并最终加载目标资源，加载完成后调用回调函数处理加载资源。

/// <summary> /// 递归异步加载资源 /// </summary> /// <param name="assetName"></param> /// <param name="action"></param> /// <returns></returns> IEnumerator LoadBundleAsync(string assetName, Action<Object> action = null) {     string bundleName = m_BundleInfos[assetName].BundleName;     string bundlePath = Path.Combine(PathUtil.BundleResourcePath, bundleName);     List<string> dependences = m_BundleInfos[assetName].Dependences;     if (dependences != null && dependences.Count > 0)     {         for (int i = 0; i < dependences.Count; i++)         {             yield return LoadBundleAsync(dependences[i]);         }     }      AssetBundleCreateRequest request = AssetBundle.LoadFromFileAsync(bundlePath);     yield return request;      AssetBundleRequest bundleRequest = request.assetBundle.LoadAssetAsync(assetName);     yield return bundleRequest;      //Log     Debug.LogFormat("Package Bundle Mode Load Resource : {0}", assetName);      action?.Invoke(bundleRequest?.asset); }

2. 编辑器模式加载资源

/// <summary> /// 编辑器模式加载资源 /// </summary> /// <param name="assetName"></param> /// <param name="actioin"></param> #if UNITY_EDITOR void EditorLoadAsset(string assetName, Action<Object> actioin = null) {     //Log     Debug.LogFormat("Editor Mode Load Resource : {0}", assetName);      Object obj = UnityEditor.AssetDatabase.LoadAssetAtPath(assetName, typeof(Object));     if (obj == null)         Debug.LogError("Asset name is not exist" + assetName);      actioin?.Invoke(obj); } #endif

3. 更新模式加载资源
