这篇文章介绍了用户在使用Rider For Unity插件时遇到的初始化缓慢问题，并通过反编译和修改插件代码，实现只扫描代码和shader文件，跳过其他非代码文件，从而大幅提升Rider启动速度，同时保留Debug和Shader提示功能。
一直以来，我都是Rider的忠实用户，它写代码真的很爽，但是随着公司项目越来越大，Rider的一个插件：Rider For Unity，其石一样的代码会导致每次Rider启动需要花几十分钟的时间，在项目中非代码文件特别多的时候，Rider打开时需要初始化非常非常久，原以为是额外扫描了非代码文件导致，但是我在Rider设置中过滤了所有非代码文件，也在这个插件的设置界面配置了大项目禁止文件索引，但结果还是一样的，但是，如果我禁用这个Unity插件，Rider就可以在1分钟之内完成初始化，开始正常工作，但是我又需要这个插件的Debug和Shader提示功能。
尝试过下载插件源码https://github.com/JetBrains/resharper-unity来重编译，但是复杂的编译模块和无数个报错让我放弃了
恰巧那阵子Cursor AI大火，我也就没继续深入研究，就转头去用Cursor了，基于VSCode的编码体验，你们懂得，经常遇到智能提示失效，缓慢的问题
又恰巧这阵子Claude以碾压姿态发布了自己的命令行工具，由于其优秀的性能和断档级领先的使用体验，国内各种中转站也是赚的盆满钵满（顺带打个广告：https://aicodewith.com/?invitation=IQCVL6U），而Claude由于其命令行的形式，可以无缝集成在各大IDE里，当我看到官网的Rider支持，不禁见景思人，回想起最近被VSCode折磨得经历，决定痛定思痛，去修复Rider For Unity这个插件。
首先，重编译插件肯定是走不通了，毕竟没有那个兴致和精力去学他们的编译模块，遂决定曲线救国：
Cursor分析插件源码，找到问题，并修复代码
直接通过dnspy反编译插件的dll，将Cursor给出的代码替换进去
Cursor 给出的答案
好的，我来直接帮您修改代码，让插件只扫描代码和shader文件，跳过所有其他文件。这样可以大幅提升性能。
让我先查看当前的文件处理逻辑，然后进行修改：
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
现在我来修改代码，让它只扫描代码和shader文件，跳过所有其他文件类型：
现在我需要添加 IsCodeOrShaderFile 方法来判断哪些文件应该被处理。让我在 ExternalFiles 类中添加这个方法：
现在让我确保有必要的 using 语句：
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
现在我需要更新大项目检测策略，因为我们跳过了大部分文件，现有的阈值可能不再适用。让我查看并调整索引禁用策略：
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
由于我们现在只处理代码和shader文件，原来的大项目检测策略就不再需要了。让我修改这部分代码：
现在让我查看并优化 FilterFiles 方法，因为我们不再处理大部分文件类型：
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
让我简化 FilterFiles 方法，因为现在我们只处理代码文件：
现在让我删除不再使用的 FilterFiles 重载方法：
让我更新 Dump 方法以反映新的文件处理逻辑：
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
Read file: resharper/resharper-unity/src/Unity/Core/Psi/Modules/UnityExternalFilesModuleProcessor.cs
让我更新 Dump 方法以反映我们只处理代码文件的新逻辑：
最后，让我在文件顶部添加一个注释来说明这个重要的性能优化：
✅ 修改完成！
我已经成功修改了代码，实现了您的需求：只扫描代码和shader文件，跳过所有其他文件类型。
🔧 主要修改内容：
新增文件类型过滤器：
只处理：.cs、.shader、.cginc、.hlsl、.asmdef、.asmref、manifest.json
跳过：.asset、.prefab、.scene、.meta、图片、音频等所有非代码文件
简化处理逻辑：
移除了复杂的资产文件分类和大项目检测
直接跳过不需要的文件，避免不必要的磁盘IO
优化日志输出：
更新了统计信息以反映新的处理逻辑
🚀 性能提升效果：
大幅减少文件扫描量：从可能的数万个文件减少到数百个代码文件
消除主线程阻塞：跳过大量文件处理，显著缩短初始化时间
保留核心功能：Debug和Shader提示功能完全保留
📋 编译步骤：
现在您可以按照之前提到的步骤编译插件：
在项目根目录运行
.\build.ps1 -Configuration Release
编译完成后，新的插件将不会扫描非代码文件，这应该能解决您遇到的初始化缓慢问题。测试时您会发现Rider启动速度明显提升，同时Debug和Shader功能依然正常工作。

Rider For Unity插件反编译
不知道从哪个版本起，Unity插件被内置到Rider了，可以从Rider主界面-帮助-特殊文件和文件夹，看到所有路径，而Rider For Unity位于C:\Users\UserName\AppData\Local\Programs\Rider\plugins\rider-unity
根据命名空间原则，我们直接找到JetBrains.ReSharper.Plugins.Unity.dll进行修改，用dnspy打开，并添加基础dll：全都位于C:\Users\UserName\AppData\Local\Programs\Rider\lib\ReSharperHost中，直接拖到dnspy窗口即可
在dnspy定位到JetBrains.ReSharper.Plugins.Unity.Core.Psi.Modules.UnityExternalFilesModuleProcessor文件
修改代码，并编译保存，如果有报错直接注释整个函数内容，只保留空函数体即可，反正我们不需要这些乱七八糟的功能
重新打开Rider，原本几十分钟的初始化时间，现在几分钟直接搞定！
拓展
当然，这只是核心问题被解决，实际上可以继续优化，比如让Cursor帮我们将文件扫描的入口整个关掉，但是不确定会不会导致其他问题，大家可以自行尝试
