Blueprint documentation is quite satisfactory.
People like me who want to speed game performance, need to use C++. API Documentation is undefined, and unexplained. It’s incomplete too.
Documentation is significant for me: I could have a one-million-dollar software on my PC, but if I don’t know how to use it, it’s useless.
We are well aware of the shortcomings of the API reference documentation. There has been a lot of effort focused on improving it for the most important and commonly used classes for gameplay programmers. Of course, that leaves tons of classes and systems that still need help. It may not be readily apparent, but we are making progress. Slow but steady.
We are looking into ways to allow all of you to make contributions in this area as well. Hopefully we will have more to share on that soon.
