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"

Removefromparent() does not work

Hello, I'm trying to display and toggle a widget (like a menu screen when hit esc) using c++. I was able to display the widget but wasn't able to toggle it on and off. The code is below GameState.cpp

 void AMyGameStateBase::SetVisible(bool v)
     Visible = v;
 bool AMyGameStateBase::GetVisible()
     return Visible;

NOTE: Visible is defined as bool in header file and initialized to false


 void AMyPlayerController::Inventory() {
     AMyGameStateBase* GameState = Cast<AMyGameStateBase>(GetWorld()->GetGameState());
     GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Blue, FString::Printf(TEXT("%i"), GameState->GetVisible()));
     if (Widgets && GameState) {
         InventoryWidget = CreateWidget<UUserWidget>(this, Widgets);
         if (InventoryWidget) {
             if (GameState->GetVisible() == true) {
                 GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Blue,TEXT("Hello!!!!"));
             else {


 void Apractice_cppCharacter::Inventory() {
     AMyPlayerController* Controller = Cast<AMyPlayerController>(GetWorld()->GetFirstPlayerController());
     if (Controller) {

and inventory() is called by using:

     PlayerInputComponent->BindAction("Inventory", IE_Pressed, this, &Apractice_cppCharacter::Inventory);

Any help is appreciated, thanks in advance!

You have no reference to the widget you have created.

Currently your code will always create a new InventoryWidget and add it to the screen, it will never get removed.

 InventoryWidget = CreateWidget<UUserWidget>(this, Widgets);

This line will always create a widget, your previously created widget no longer has a reference and is now just in memory.
