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"

OnAudioFinished not called for USoundWaveProcedural

I have a class extended from USoundWaveProcedural:

 class UMySoundWave : public USoundWaveProcedural
         bool Initialize();
 UMySoundWave::UMySoundWave(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer) {}
 bool UMySoundWave::Initialize()
     uint32 BytesRead;
     uint8 *AudioBuffer = ...;// HERE: GENERATE PCM DATA AND FILL BytesRead
     NumChannels = 1;
     SampleRate = 44100;
     Duration = (BytesRead / 2) / 44100.0;
     SoundGroup = SOUNDGROUP_Voice;
     QueueAudio(AudioBuffer, BytesRead);
     delete AudioBuffer;
     return true;

The problem is when I use SpawnSoundAttached with this sound, OnAudioFinished never called.

Did you ever figure this out?

I've been struggling with the same issue for the past few days now. I'm considering just putting in a delayed event where the delay = the length of the audio, but that just feels sloppy...

I did the same - timer as a solution/workaround.
