  • 《Debug UE4/3 FString》

    UE3或者UE4的FString类型无法在内存中直接看到值，为了debug方便，需要第三方文件的协助，可以将以下两个文件UE3.natvis和UE4.natvis拷贝到$USERPROFILE/Documents/Visual Studio 2012/Visualizers 目录下，在debug的时候可以实时看到FString的值了：

    下面的sh执行文件可以用于一键执行：

    #!/bin/bash

cp_args="-v --preserve=timestamps"
cp $cp_args UE{3,4}.natvis    "$USERPROFILE/Documents/Visual Studio 2012/Visualizers"
cp $cp_args UE{3,4}.natvis    "$USERPROFILE/Documents/Visual Studio 2013/Visualizers"
cp $cp_args PS4UE{3,4}.natvis "$USERPROFILE/Documents/SCE/orbis-debugger"

    注意在以上几个文件中更改自己所使用的VS版本号使之与本机VS版本一致；
