【Unity&XLua】热更新框架 | Bundle构建_xlua热更新游戏框架

框架开发

1. Bundle处理（构建-加载-更新）
2. C#调用Lua（Lua加载与管理、Lua绑定与执行）
3. 向Lua提供接口
4. 完善和优化

资源目录划分

将Assets根据是否需要打bundle分类

1：Lua，UI,模型，特效，声音，动画
0：
  xlua
  c#：
    bundle构建工具等工具
    与Lua交互：
        c#调用Lua（加载Lua脚本，执行Lua逻辑）
      Lua调用c#（c#给Lua提供接口用于资源加载、资源管理、事件管理、场景模型加载等）`

Bundle构建

xLua下载链接：xLua
解压后Assets下的文件导入Unity

策略：对每个单独文件打包bundle
使用Unity提供的BuildPipeline构建

//BuildPipeline(输出路径，数组列表，压缩格式，bundle目标平台）
        BuildPipeline.BuildAssetBundles(PathUtil.BundleOutPath, assetBundleBuilds.ToArray(), BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);

查找BuildResources下的资源文件

//获取所有文件策略 GetFiles(路径，搜索的匹配字符串，搜索选项：全部文件夹)
        string[] files = Directory.GetFiles(PathUtil.BuildResourcesPath, "*", SearchOption.AllDirectories);

生成标签：

[MenuItem("Tools/Build Windows Bundle")]
    static void BundleWindowsBuild()
    {
        Build(BuildTarget.StandaloneWindows);
    }

放入UI

运行Build Windows Bundle
结果：路径斜杠混乱

对路径规范处理：

public static string GetStandardPath(string path)
    {
        if (string.IsNullOrEmpty(path))
            return string.Empty;
        return path.Trim().Replace("\\", "/");
    }

Code

PathUtil.cs

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

public class PathUtil
{
    //根目录
    public static readonly string AseetsPath = Application.dataPath;
    //需要打bundle的目录
    public static readonly string BuildResourcesPath = Application.dataPath + "/BuildResources";
    //bundle输出目录
    public static readonly string BundleOutPath = Application.streamingAssetsPath;
    
    public static string GetUnityPath(string path)
    {
        if (string.IsNullOrEmpty(path))
            return string.Empty;
        return path.Substring(path.IndexOf("Assets"));
    }

    //获取标准路径
    public static string GetStandardPath(string path)
    {
        if (string.IsNullOrEmpty(path))
            return string.Empty;
        return path.Trim().Replace("\\", "/");//替换
    }
}
