I am looking for the implementation of “Make Map” node in c++.

It’s a very special node since it has two different wildcards.

In Macro I can’t have two wildcards with different types. So I want to make a custom node in C++ like “Make Map”.

Basically I am trying to make a Map iterator node in blueprint. I hard code it every time i need it but that’s not satisfying ☹

All nodes are based out of UK2Node class (K2 = Kismet 2 as blueprint is evolution of Kismet from UE3) so you can find it here: `Source/Editor/BlueprintGraph/Private/K2Node_MakeMap.cpp`
