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"

Overriding CPP functions in blueprint

It seems like I am only able to override BlueprintNativeEvent functions, but what in the case I want the function to return something? I tired overriding BlueprintCallable but the editor just gives me signature error.

Product Version: UE 4.12

You can't override C++ functions, blueprint virtual machine can't manipulate machine code (produced by C++) that is executing in C++. What BlueprintNativeEvent does is create a illusion of it, by injecting C++ code (UHT does that in compilation time) which decides to either execute C++ function or blueprint function in virtual machine.

BlueprintNativeEvent supports return value events if i remember right in fact they are used in GameMode class, events with return value will apper in "Override" button in "Functions" type in the list of stuff in blueprint editor, it creates event blueprint function where you can return stuff.
