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"

Why is SpawnActor() returning NULL?

Blockquote

I am spawning two pawns in the BeginPlay() in my game mode class like so:

     FActorSpawnParameters SpawnParams;
     SpawnParams.Owner = this;
     SpawnParams.Instigator = Instigator;
     FVector LeftPawnLocation = FVector(0, 2450, 1500);
     FVector RightPawnLocation = FVector(0, -2450, 1500);
     FRotator PawnRotation = FRotator(0.0f, 0.0f, 0.0f);
     UWorld* const PongWorld = GetWorld();
 
     if (PongWorld) {
         FirstPlayer = PongWorld->SpawnActor<APongPaddlePawn>(LeftPawnLocation, PawnRotation, SpawnParams);
         SecondPlayer = PongWorld->SpawnActor<APongPaddlePawn>(RightPawnLocation, PawnRotation, SpawnParams);
     }

When I debug, i try to set the size of the pawns of FirstPlayer and SecondPlayer and they are both NULL. I can see the pawns showing up in my game. Why are they both NULL?

Try giving the SpawnActor the class you want to spawn. For example:

 // h
 UPROPERTY()
 TSubclassOf<APongPaddlePawn> PongPaddlePawnClass;
 
 // cpp
 FirstPlayer = PongWorld->SpawnActor<APongPaddlePawn>(PongPaddlePawnClass, LeftPawnLocation, PawnRotation, SpawnParams);
