Thanks Rama !
The Entry Level Guide to UE4 C++ ( https://wiki.unrealengine.com/Entry_Level_Guide_to_UE4_C%2B%2B ) is a godsend.
I have been programming (or you could say scripting) for 15 years but never learned C++. I was fairly comfortable with Unrealscript but the switch to C++ has been a nightmare for me. Lost at the first step. This entry level guide was a great way to learn how to reference and point to instantiate a memory optimised reference to code. Something I have done a million times yet never in C++.
The wiki is now a staple of my favourites. Thanks again !
