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"

Refer blueprint enum in C++

I have a BP enum:

And I want to create a C++ function that adds a BP node that returns this enum. Something like that:

How can I achieve this?


P.S. My C++ function now:

 UFUNCTION(BlueprintCallable, Category = "Tiny Dungeon")
 static int ChooseBestDirection(int leftWeight, int rightWeight, int topWeight, int bottomWeight)
 {
     return 0;
 {

I do not believe you can refer to non-C++ enums in C++. What you can do is convert your int return value to a byte (ToByte(Integer) in blueprint). You can then drag this byte value into your enum node and it will convert the byte to your enum type.

As a quick fix that will do but I would rather just make the Enum in C++ and expose it to Blueprint. The entire point of Enumerations is that you reference it by name and avoid magic number errors.

Looks like it is a best solution. Thank you.
