UE5使用过程问题记录

标签：__ obj 记录 void project cpp error UE5 过程

一、 Action RPG编译报错

使用U5打开UE Demo Action RPG

Demo链接：https://www.unrealengine.com/marketplace/en-US/product/action-rpg-01

现象：

使用UE5打开此Demo时，在编译时，会提示找不到插件“SlateRemote”

解决方法：

可以直接打开ActionRPG.uproject，然后把“SlateRemote”的Enabled改成false，重新编译即可

二、启动UnrealEditor的报错

现象：

启动UnrealEditor的报错：

Plugin 'RuntimePhysXCooking' failed to load because module 'RuntimePhysXCooking' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.

解决方法：

Engine\Binaries\Win64\UnrealEditor.modules里面，补充一下

"PhysXCooking": "UnrealEditor-PhysXCooking.dll",

怀疑是装rider的插件把这个文件搞坏了

三、UE编译时msado15.tlh报错

现象：

重新编译UE5时，报错：

1>[1/9] Touch msado15.tlh

1>[1/9]Touch msado15.tlh - Error but no output

解决方法：

参考：https://zenn.dev/shiena/scraps/19d01c0ad6af72

删掉这个目录：“Engine\Plugins\Runtime\Database\ADOSupport\Intermediate\Build\Win64\UnrealEditor\Development\ADOSupport”

四、UE编译成Game时，链接GLiveCodingEngineDir报错

原因：

存在多个IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, Game, "Game" )

只允许存在一个，其它的要改成：

class FSomeModuleGameModule : public FDefaultGameModuleImpl
{
};

IMPLEMENT_GAME_MODULE(FSomeModuleGameModule, SomeModule);

五、UE编译成Game时，链接GIsGameAgnosticExe报错

现象：

error LNK2001: unresolved external symbol “bool GIsGameAgnosticExe” (?
Error 2 error LNK2001: unresolved external symbol “bool GIsGameAgnosticExe” (?
Error 3 error LNK2001: unresolved external symbol “wchar_t * GGameName” (?GGameName@@3PA_WA)

原因：

没有IMPLEMENT_PRIMARY_GAME_MODULE

解决方法：

把其中一个模块改成IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, Game, "Game" ) 其中Game自己命名。

六、UE启动时，提示游戏模块加载后，无法被成功初始化

现象：

The game module 'xxx' could not be successfully initialized after it was loaded.

原因：
没有给模块'xxx'添加相应的模块初始化文件，类似这个：

class xxx : public FDefaultGameModuleImpl

解决方法：
在模块的根目录下，添加相应的模块初始化文件即可
