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"

I'm not sure if this will answer your question, but one way of getting your USTRUCT into an array of bytes can be done like so:

 struct FSaveMyStruct
     int32 AnyInt32;
 FSaveMyStruct MyStructInstance;
 MyStructInstance.AnyInt32 = 77;
 FBufferArchive Buffer(true);
 FSaveMyStruct::StaticStruct()->SerializeBin(Buffer, &MyStructInstance);
 TArray<uint8> Bytes = Buffer;

Since FBufferArchive inherits from TArray you could just use any TArray functions on Buffer. Hope this helps.

Oh, dunno how I missed it. I saw there is JSON automatic serializer and wanted to implement my own binary. Now I don't need to do it, Thank you!
