Is there any text based programming environment for it? the one thing game engines like unity or unreal get right IMO is having a pretty GUI for doing basic things and prototyping while still having the text based programming available to modify further
I don't know (I haven't used the editor, my work network blocks domains with "game" in it) but in most of the "no code" solutions I've tried it's simply faster to define things in text than to try and figure out how to represent that with the graphical tools given. It also allows for code to be transferred between projects easier
