本文主要是介绍[游戏开发][Unity]Assetbundle打包篇（2）打包资源配置篇，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

目录

打包与资源加载框架目录

正文

可视化配置的方式有很多种，Json、XML、以及Unity内置的ScriptableObject序列化

配置文件里要有哪些内容呢，很显然，最重要的就是目标文件路径，其次是权重类型，权重类型有：必要打包型、被引用打包型、忽略类型。为何会有忽略类型呢，是因为我们设置目标文件路径是个文件夹，同文件夹内可能有不想被打包的文件夹，因此，我们需要另开一条配置，把该子文件夹也设置进去，并且权重类型设置为：忽略类型即可。被引用打包型比较好理解，虽然该资源在目标文件路径中，如果最终统计该资源被引用的次数等于0，说明该资源不需要进包。

我选择的是使用 ScriptableObject，其可视化内容可以参考下图。

我安装了Odin Inspector插件所以Inspector面板是可以直接操作的，有需要自行安装。

CollectionSetting顾名思义就是收集配置，请注意还有一些比较特殊的配置

PackRule设置

PackRule看三个变量就知道是对文件夹是否收集的操作

  1. Collect必须收集该文件夹

  1. Ignore必须忽略该文件夹

  1. Passive 该文件夹被引用时收集

LabelRule

这里要重点强调一下这个规则的作用，我们测试项目中，所有的资源都在一个根目录下Assets/Works/Resource，看我时如何运用LabelRule规则对根目录下的子文件夹实现控制，如下图所示

首先，根目录Assets/Works/Resource设置为LabelByFilePath,意思是说，该目录下的每一个子文件夹内文件，都要单独打成一个AB包，那疑问就来了，每个文件一个AB包，肯定太碎了。

所以就有了第二步操作，第二个操作就是设置根目录的子文件夹Assets/Works/Resource/Sprite/BuffIcon 的LabelRule为LabelByFolderPath，意思是以文件夹路径打包。子路径的LabelRule可以覆盖根路径的LabelRule

还有一个重点提示的内容就是，有些文件我们想以文件夹打包，但是！部分子文件太大了，比如好几十M，因此还有个特殊选项LabelByFolderPathExceptBig，意思是，该文件夹还是打成一个整包，但是过大的文件，会根据自己的路径生成一个单独的AB包。

具体代码请看下面的第三个方法

EncryptRule加密规则

加密规则的作用是，AB包打出来后，使用我们规定的加密方式，对AB包数据进行处理，从而让外部的人无法查看包内容。这些加密方式都是自己定的，没有特定的规则

Quick模式：往AB包二进制数据前插一段数据，等将来读取的时候再把插入部分删掉。插入部分你可以自己定义，就算塞入一个数，也可以起到加密作用，只不过别人还是有办法破解，我的Quick模式是用该AB包的Hash生成了一个二进制key插进去，加载AB包时用Hash再算出来这个key，把这个key删掉读包。

BundlePos设置

buildin模式启动时要热更进APP，ingame模式比较特殊，边玩边下载。

CollectionSettingData脚本是用来管理使用CollectionSetting配置的脚本，该CollectionSettingData提供了4个基本的方法供搜集资源时使用。

下面是CollectionSettingData的全部代码，部分代码在下面单独讲解

}/// <summary>
/// 获取资源的打包位置
/// </summary>
public static EBundlePos GetAssetBundlePos(string assetPath)
{// if (assetPath.Contains("Assets/WorksArt/Model/Live2D")//      || assetPath.Contains("Assets/Works/Resource/Audio/live2D")//      || assetPath.Contains("Assets/Works/Resource/Model/Live2D"))// {//     return EBundlePos.ingame;// }List<string> buildInList = ConfigParser.GetBuildInResList();foreach(string path in Setting.InGames){if (assetPath.Contains(path)){bool match = false;foreach (string name in buildInList){if (assetPath.Contains(name)){match = true;break;}}if (match)break;elsereturn EBundlePos.ingame;}}// 注意：一个资源有可能被多个规则覆盖List<CollectionSetting.Wrapper> filterWrappers = new List<CollectionSetting.Wrapper>();for (int i = 0; i < Setting.Elements.Count; i++){CollectionSetting.Wrapper wrapper = Setting.Elements[i];if(IsSubPath(wrapper.FolderPath, assetPath)){filterWrappers.Add(wrapper);}}// 我们使用路径最深层的规则CollectionSetting.Wrapper findWrapper = null;for (int i = 0; i < filterWrappers.Count; i++){CollectionSetting.Wrapper wrapper = filterWrappers[i];if (findWrapper == null){findWrapper = wrapper;continue;}if (wrapper.FolderPath.Length > findWrapper.FolderPath.Length)findWrapper = wrapper;}// 如果没有找到命名规则if (findWrapper == null){return EBundlePos.buildin;}return findWrapper.BundlePos;
}public static void ApplyReplaceRules(ref string name)
{if (name.Contains("TempLuaCode")){name = name.Replace("TempLuaCode", "Lua");}if (name.Contains("Resource_min")){name = name.Replace("Resource_min", "Resource");}
}}

2：获取所有资源配置信息，是一个很重要的接口，代码在上面也有

    public static List<string> GetAllCollectPath(){List<string> result = new List<string>();for (int i = 0; i < Setting.Elements.Count; i++){CollectionSetting.Wrapper wrapper = Setting.Elements[i];if (wrapper.PackRule == CollectionSetting.EFolderPackRule.Collect)result.Add(wrapper.FolderPath);}return result;}

3：获取该资源目录的AssetbundleLabel，不知道AssetbundleLabel的小伙伴，看下图

/// <summary>
/// 获取资源的打包标签
/// </summary>
public static string GetAssetBundleLabel(string assetPath)
{// 注意：一个资源有可能被多个规则覆盖List<CollectionSetting.Wrapper> filterWrappers = new List<CollectionSetting.Wrapper>();for (int i = 0; i < Setting.Elements.Count; i++){CollectionSetting.Wrapper wrapper = Setting.Elements[i];if (IsSubPath(wrapper.FolderPath, assetPath))filterWrappers.Add(wrapper);}// 我们使用路径最深层的规则CollectionSetting.Wrapper findWrapper = null;for (int i = 0; i < filterWrappers.Count; i++){CollectionSetting.Wrapper wrapper = filterWrappers[i];if (findWrapper == null){findWrapper = wrapper;continue;}if (wrapper.FolderPath.Length > findWrapper.FolderPath.Length)findWrapper = wrapper;}// 如果没有找到命名规则if (findWrapper == null) return assetPath.Remove(assetPath.LastIndexOf("."));string labelName = "";// 根据规则设置获取标签名称if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.None){// 注意：如果依赖资源来自于忽略文件夹，那么会触发这个异常throw new Exception($"CollectionSetting has depend asset in ignore folder : {findWrapper.FolderPath}, asset : {assetPath}");// MotionLog.Log(ELogLevel.Log, $"CollectionSetting has depend asset in ignore folder : {findWrapper.FolderPath}, asset : {assetPath}");// labelName = assetPath.Remove(assetPath.LastIndexOf("."));}else if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByFileName){labelName = Path.GetFileNameWithoutExtension(assetPath); // "C:\Demo\Assets\Config\test.txt" --> "test"}else if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByFilePath){labelName = assetPath.Remove(assetPath.LastIndexOf(".")); // "C:\Demo\Assets\Config\test.txt" --> "C:\Demo\Assets\Config\test"}else if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByFolderName){string temp = Path.GetDirectoryName(assetPath); // "C:\Demo\Assets\Config\test.txt" --> "C:\Demo\Assets\Config"labelName = Path.GetFileName(temp); // "C:\Demo\Assets\Config" --> "Config"}else if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByFolderPath){labelName = Path.GetDirectoryName(assetPath); // "C:\Demo\Assets\Config\test.txt" --> "C:\Demo\Assets\Config"}else if (findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByFolderPathExceptBig){long sizeMB = EditorTools.GetFileSize(assetPath) / 1024;if (sizeMB < bigSizeMB)labelName = Path.GetDirectoryName(assetPath); // "C:\Demo\Assets\Config\test.txt" --> "C:\Demo\Assets\Config"elselabelName = assetPath.Remove(assetPath.LastIndexOf(".")); // "C:\Demo\Assets\Config\test.txt" --> "C:\Demo\Assets\Config\test"}else if(findWrapper.LabelRule == CollectionSetting.EBundleLabelRule.LabelByRootFolderPath){labelName = findWrapper.FolderPath;}else{throw new NotImplementedException($"{findWrapper.LabelRule}");}ApplyReplaceRules(ref labelName);return labelName.Replace("\\", "/");
}

4：获取该资源的BundlePos，BundlePos是什么，前文已经介绍了

public static EBundlePos GetAssetBundlePos(string assetPath)
{
// if (assetPath.Contains("Assets/WorksArt/Model/Live2D")
//      || assetPath.Contains("Assets/Works/Resource/Audio/live2D")
//      || assetPath.Contains("Assets/Works/Resource/Model/Live2D"))
// {
//     return EBundlePos.ingame;
// }
List<string> buildInList = ConfigParser.GetBuildInResList();foreach(string path in Setting.InGames)
{if (assetPath.Contains(path)){bool match = false;foreach (string name in buildInList){if (assetPath.Contains(name)){match = true;break;}}if (match)break;elsereturn EBundlePos.ingame;}
}// 注意：一个资源有可能被多个规则覆盖
List<CollectionSetting.Wrapper> filterWrappers = new List<CollectionSetting.Wrapper>();
for (int i = 0; i < Setting.Elements.Count; i++)
{CollectionSetting.Wrapper wrapper = Setting.Elements[i];if(IsSubPath(wrapper.FolderPath, assetPath)){filterWrappers.Add(wrapper);}
}// 我们使用路径最深层的规则
CollectionSetting.Wrapper findWrapper = null;
for (int i = 0; i < filterWrappers.Count; i++)
{CollectionSetting.Wrapper wrapper = filterWrappers[i];if (findWrapper == null){findWrapper = wrapper;continue;}if (wrapper.FolderPath.Length > findWrapper.FolderPath.Length)findWrapper = wrapper;
}// 如果没有找到命名规则
if (findWrapper == null)
{return EBundlePos.buildin;
}return findWrapper.BundlePos;
}
