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"

UE_LOG No constructor could take the source type, or constructor overload resolution was ambiguous

Hey guys, so I defined a custom macro to log out of a tutorial somewhere on YouTube

 #define __FUNCTION__String                                    FString(__FUNCTION__)
 #define __LINE__String                                        FString(__LINE__)
 /** Helper to log with class name, function identifier, and line number included */
 #define DH_LOG(CategoryName, Verbosity, Format, ...)        UE_LOG(CategoryName, Verbosity, TEXT("%s [%s]: %s"), *__FUNCTION__String, *__LINE__String, *FString(Format), __VA_ARGS__)

However, when using the VA_ARGS parameter to enter in an FString with TEXT("%s")

 DH_LOG(LogOnlineGame, Display, TEXT("Starting session %s on client"), *DHPlayerState->SessionName.ToString());

Compiler outputs this error:

 1>D:\Library Storage\Unreal Projects\DistantHome\Source\DistantHome\Private\Player\DHPlayerController.cpp(193): error C2440: '<function-style-cast>' : cannot convert from 'int' to 'FString'
 1>          No constructor could take the source type, or constructor overload resolution was ambiguous

So how do I resolve this?

Here's the full UBT log, just in case: http://pastebin.com/QXBRkYzA
