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"

[DOC REQUEST] Detail on exposing C++ elements to Blueprints

Hi, the documentation Extending Blueprints lacks any specific details about creating properties and functions with the various types of parameters possible in blueprints.

I had to experiment to find out the "correct" way to expose inputs and outputs. It would be great if this documentation included a table of parameter types and a number of examples so that everyone doesn't have to go through this guesswork.

The error messages when you guess wrong (e.g. I tried int32* when trying to get an out parameter happening) so some clear docs would be much appreciated.

Something like:

In parameters: - Text: const FText& - Int: int32

Out parameters: - Int: int32& - etc

I agree there were a few issues I had with the blueprint function specifiers because functions need to be declared in certain places and with seperate _Implementation functions.

There is also one where a blueprint type wont show break structure unless each of its properties are also declared UProps.
