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"

Receiveing data by UDP don't work

 uint32 Size;
     while (ListenSocket->HasPendingData(Size))
         uint8 *Recv = new uint8[Size];
         int32 BytesRead;
         ListenSocket->Recv(Recv, Size, BytesRead);
         //Do something with the received data
         char ansiiData[1024]; //A temp buffer for the data
         memcpy(ansiiData, Recv, BytesRead); //Assumes bytesRead is always smaller than 1024 bytes
         ansiiData[BytesRead] = 0; //Add null terminator
         FString debugData = ANSI_TO_TCHAR(ansiiData);
         ListenSocket->RecvFrom(Recv, Size, BytesRead, *targetAddr);
         GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, "Message " + debugData);

Above is my code No errors no data received
