Full support for textual scripting BluePrints would help a lot instead. Because BluePrints are a real mess to deal with visually for complex algorithms. There is an unsupported/unofficial way of seeing the actual script for the visual part thru copy/paste but it still is an hack and it is just undocumented.
I would code everything in C++ if that was possible but most APIs aren’t documented at all and for some things C++ just can’t be used and BluePrint is the only way.
So official support for text version of BluePrints would help a lot. But I still hope Epic Games will release full documents for proper C++ coding of all the APIs in UE4. And that UE5 won’t have any of these issues anymore when it happens.
Reading online documents about the old UDK it shows that it was well documented on practically everything… probably because it was a very expensive premium product for big software houses only that were able to afford the license… While it seems that UE4 being almost free is not getting the same level of care about releasing full documents to the public, unless the big software houses are getting full documents anyway, otherwise the whole C++ part of UE4 wouldn’t be so badly documented as it still is right now so forcing developers to use BluePrints even when they wouldn’t.
