ue 配置c++环境

ue5.3，蓝图项目新建了个c++脚本，然后工程打不开了，删除多余文件，工程文件记事本打开，删掉mould里的内容，可以重新打开。

网上查了查内容，ue5.3需要使用的vs2022版本17.4到17.8。而我是17.14 。需要回退版本。由于我这没有规定好版本，所以下载了最新的ue5.6进行测试。

5.6可以打包之类的正常，但是新建c++类会有很多报错，重新下载5.5测试

直接新建ue5.5的c++项目。自动打开了vs2022 。右上角提示有依赖项需要安装，点安装会自动安装环境。

重启后查看自动弹出的集成配置。

提示需要安装visual studio integration tool，我这点安装到项目，一直失败，打开steamcommunity_302，并且配置里把github选上，点击手动配置可以正常打开github。这时候再点击安装到引擎就好使了。此时在ue引擎的插件里也会多了visual studio integration tool。

ue命名约定检查器状态为警告，点击详细了解命名约定规则，找到an .editorconfig file  ，点击进入。复制全部内容，点添加，然后选择文件夹，把内容复制进去。我这自动就生成了，不需要复制。

HLSL支持也一样，点配置，点确认，会自动生成文件。

这时候点总体配置状态的刷新按钮，全部显示为绿色。

这时候重启ue引擎，可以正常打开。

相同的操作在ue5.3中就不好使，也许需要回退vs版本，暂没试验。

这可能是模块依赖缺失，打开.build.cs文件，修改

PublicDependencyModuleNames.AddRange(new string[] {
    "Core", "CoreUObject", "Engine", "InputCore", 
    "UMG",  // 添加 UMG 模块支持 UI
    "Slate", "SlateCore"  // 添加 Slate 模块支持 UI 渲染
});

// 如果是 5.0+ 版本，可能需要添加:
PrivateDependencyModuleNames.AddRange(new string[] {
    "ApplicationCore"  // 确保 ApplicationCore 模块被包含
});

因为live coding，导致无法再打开ue编辑器的时候编译vs的c++代码。这时候关闭ue编辑器就行。

vs工程中有很多的莫名其妙错误，把下方的选项改为仅生成。
