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"

Using SoundCue in actor class?

I would like to access a SoundCue in one of my actor classes. I have an Actor class which contains a UAudioComponent member. The AudioComponent member is assigned a SoundCue class using AudioComponent::SetSound(). I set which SoundCue to use from the UE4 editor. THe AudioComponent member is then exposed through a blueprint method. I call Play() on it from my Blueprint. Only problem is I get no sound. Maybe it's my BluePrint? Or is this doomed to fail from the onset?!

My Actor header contains the following:

 UPROPERTY(EditAnywhere, Category = "Sound")
 USoundCue* SoundCue;

 UPROPERTY()
 UAudioComponent* audioComponent;

 UFUNCTION(BlueprintCallable, Category = "Sound")
 UAudioComponent* getAudioComponent()
 {
     audioComponent->Sound = SoundCue;
     return audioComponent;
 }

I've checked the validity of the AudioComponent, and the SoundCue, and they are both valid. Any ideas?

I guess I can just call UGameplayStatics::PlaySound2D or something like that. I thought it might be better to expose the AudioComponent but perhaps this is cleaner.
