This is my favorite Unreal 4 demo - [VIDEO] (sadly missing the wonderful quote "I light my level by dropping a sun in.") I'm completely in awe of the feedback loop here. It even compiles and swaps code while you're in the game!

I believe that on Unreal Engine 4, you use C++ and it does have a feature that mimics "live coding" where it recompiles and hot-reload your game even while playing. edit: here it is [VIDEO] (jump to 9:40 if it doesn't load at this point automatically)

A few years ago (2012) I was taken aback by the Unreal Engine development process. Their IDE features a running game with all elements being selectable and interactively editable. In one video fragment [1] they hop to Visual Studio where they change gravity. After a few seconds of compilation, the game's code is updated. [1] [VIDEO]
