UE4 contacted for some time, from the beginning has been using BP (Blueprint), feeling BP function is indeed very powerful, but encountered some embarrassing questions during use, such as:
Although BP class can inherit C ++ classes, and C ++ classes can inherit BP class, but in the same way when using UMG bit helpless, and I think when an event such as the occurrence of at UMG (such as a button is clicked)
Inform other blueprints (here a checkpoint blueprint for example)?
Or a simple user login when the input is complete, you need to send the information about user name, password, etc. to the server, the same will happen very embarrassing thing. (Here I was thinking that when input is complete click Submit Get in C ++ to input information)
I hope they see the older generation can do a detailed tutorial busy, in this grateful!
