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"

Custom struct as key in TMap that will be JSON serialized

Hey all,

So I have a USTRUCT that I'm using as a key in a TMap and that is working correctly after overriding operator== and GetTypeHash (the main member is an FString )

This TMap is also serialized to JSON though and I'm getting JSON serialization errors when it attempts to serialize:

LogJson: Error: Json Value of type 'Object' used as a 'String'.

I think it's because for UStructProperty that acts as the key internally doesn't have HasExportTextItem & ExportTextItem implemented in the CppStructOps, but I'm not sure how exactly to set up my USTRUCT.

Any help greatly appreciated.

Many thanks,
