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"

Not sure i understand this one. I've seen a few other similar posts but no answer seems to work for me.

Are you sure? Breakpoints cut the execution before the node they are on is executed.

Can you "Step Over" and see if the value is filled?

Can you also show the watched variables in the "Blueprint Debugger" tab as (for me) the bubbles are hard to track.

I suspect that the "ToText (string)" node does not return a proper value from the screenshot but I'll have to try it.

Well. I'm getting "Variable not in scope" error on the image and totext part.

Oh how silly of me. I was deleting the object while this was all happening... That's why half way through it loses reference. MAtttt Daemmonnnn

I was deleting the object:

 void AInteractiveActor::PickUp_Implementation(AActor* item)
     if (item->GetClass()->ImplementsInterface(UInteractiveItem::StaticClass()))
         IInteractiveItem* interactiveItem = Cast<IInteractiveItem>(item);
         if (AInventoryItem* inventoryItem = Cast<AInventoryItem>(interactiveItem))
             APlayerPawnController* playerPawnController = Cast<APlayerPawnController>(GetWorld()->GetFirstPlayerController());

so half way through the blueprint running, the ref was removed. Clever me :)
