Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Widget cannot be created after openlevel() GameInstance

I tried to call "OpenLogin()" function in Init() function but it didn't work in no way.

I checked this, https://answers.unrealengine.com/questions/272995/umgwidget-dont-show-from-gameinstance.html

"When "Event Init" is called no "PlayerController" exist yet in your level , to solve that add a "delay" node (ex 0.05sec) before you create your widget" 'Mhousse1247

As far as I understand, in Init function, we cannot create widgets because some objects are not installed yet.

This time I call the functions in OnStart(). if I remove this line "OpenLevel(LEVEL::LOGIN)", it works.

Here is my game instance.

 class X_API UGameManager : public UGameInstance, public FTickableGameObject
     {
     ...
     static UGameManager game_manager; // initialized in .cpp
     
     UPROPERTY() ULevelManager* level_manager;
     UPROPERTY() ULoginWidget* login_widget;
     ...
     Init()
     OnStart()
     }
     
     Init()
     {
     game_manager = this;
     Creating level_manager, login_widget
     }
     
     OnStart()
     {
     level_manager->OpenLogin()
     }


 class ULevelManager : UObject
 {
 void OpenLogin()
  {
 OpenLevel(LEVEL::LOGIN)
             
 GameManager->LoginWidget->ConstructWidget() --  this doesn't work
             
 GameManager->GetWorld()->SpawnActor<AActor>(); -- this doesn't work either
 }
             
  void OpenLevel(uint16 level){....UGamePlayStatics::OpenLevel(..)....}
 }


 class   ULoginWidget : UObject
 {
 void ConstructWidget()
 {  
 CreateWidget()
  ...
 ....
 }
                 
 void CreateWidget()
 {
  LoginWidgetClass = LoadObject<UClass>(nullptr, LOGINWIDGETCLASS_PATH);
 checkifnull(LoginWidgetClass)
                 
 LoginWidget = ::CreateWidget<UUserWidget>(UGameManager::Instance()->GetWorld(), LoginWidgetClass);
 checkifnull(LoginWidget)
                 
 LoginWidget->AddToViewport();
 
  }
  }

Thanks.
