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"

Can I use switch case in C++ with FString?

Hi, I'm making XML parsing code with FXmlNode. I want to iterate through GetChildrenNodes(), and use switch-case with FString which is return value of FXmlNode::GetTag(). Is there someway to do that? Or should I use

 if (Tag == TEXT("XX") ..
 else if (Tag == TEXT("YY"));

Thanks.

Well no, it is a limitation from FString, and every string type in UE, but you can use a trick, you can make a TArray with FNames from your FStrings, then set a number for everyone, and then get every number in the switch, but to be honest just use if and else, is less annoying.

 FString hey = "hey";
 FName ConvertedFString = FName(*hey);
     
 switch (ConvertedFString.GetNumber())
 {
     case 1:
     {
 
     }
 }
