unreal-engine4 - 虚幻错误：使用 -cook 或 -cookonthefly 需要游戏目标

问题描述

在 Unreal Engine 4.26.2 上，我正在尝试为 Win64 打包 Blueprint/C++ 混合项目。

但是，我遇到了以下错误：

LogMainFrame: Project does not require temp target
LogLauncherProfile: Found promoted target with matching version at ../../../Engine/Binaries/Win64/UE4Game-Win64-Shipping.target

完整异常跟踪的相关部分是：

Program.Main: AutomationTool exiting with ExitCode=1 (Error_Unknown)

是否存在“未找到游戏目标”的常规原因？

解决方案

虽然不清楚它为什么起作用，但复制Source目录中的默认 projectname.Target.cs 文件并将其重命名为 projectnameGame.Target.cs（并更改该文件的内部类名以匹配）似乎可以解决问题。目录中现在有 3 个Target.cs文件Source。

  • 项目名.Target.cs
  • 项目名称Game.Target.cs
  • 项目名称Editor.Target.cs

那时一切都恢复了......这看起来很奇怪，但它有效！
