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"

Thanks!

You could bind a lambda and then capture what you want. Even if it needs to be an UFunction just make a wrapped with the lambda and call your inner UFunction with the captured members.

Hey Moss, would it be possible for you to post a code snippet showing how to do that? I'm having a hard time figuring out how to get a UFunction pointer from a lambda. Thanks!

You could do something like:

 void UMyClass::FunctionWithVar(const FString& MyVar, TFunction<void(const FString&)> InFunction)
 {
     MyLambdaHandle = OnMyDelegate.BindStatic([MyVar](TFunction<void(const FString&)> callback) {
         callback(MyVar);
     }, InFunction);
 
     // TODO: You have to track MyLambdaHandle to be able to unregister it when needed
 }

Note: It's all hand written and may not compile
