UE5 项目设置

• 1、定义设置哪些参数

  UCLASS(config=Engine, globaluserconfig)
  class ADVMOD_API UGlobalSettings : public UObject
  {
  	GENERATED_BODY()
  
  public:
  	UGlobalSettings();
  
  const FString& GetPythonExePath() const { return PythonExePath.FilePath; }
  	
  private:
  	UPROPERTY(config, EditAnywhere, Category = "Path", meta = (DisplayName = "Python exe path"))
  	FFilePath PythonExePath;
  	
  	UPROPERTY(config, EditAnywhere, Category = "Path", meta = (DisplayName = "Python64"))
  	bool x64;
  };
  

• 2、模块启动时，注册

  void FAdvModModule::StartupModule()
  {
  	 项目设置 /
  	RegisterSettings();
  }
  
  void FAdvModModule::RegisterSettings()
  {
  	ISettingsModule* SettingsModule = FModuleManager::GetModulePtr<ISettingsModule>("Settings");
  	if (!SettingsModule) return;
  	
  	SettingsModule->RegisterSettings("Project", "Plugins", "AdvGlobalSettings", FText::FromString("Adv"), FText::FromString("Configure the Adv plugin."), GetMutableDefault<UGlobalSettings>());
  }
  

  • 卸载

    void FAdvModModule::ShutdownModule()
    {
    	UnregisterSettings();
    }
    
    void FAdvModModule::UnregisterSettings()
    {
    	ISettingsModule* SettingsModule = FModuleManager::GetModulePtr<ISettingsModule>("Settings");
    	if (!SettingsModule) return;
    	
    	SettingsModule->UnregisterSettings("Project", "Plugins", "AdvGlobalSettings");
    }
    

• 3、使用

  GetDefault<UGlobalSettings>()->GetPythonExePath();
