the fork is maintained uptodate regularly so if you build from that fork you’ll have latest mx2 with some more docs on core language. It’s not perfect though..
abakobo, I tried the docs link, yes, it is in there and many more. Good, I am writing a Monkey2 reference page for myself step by step, that helps a lot, thanks.
gridshooter sample is itself a 2d game engine, I am impressed! The game sample shows many interesting language features of Monkey2. This is way beyond BlitzMAX. I donated last year, monthly donation on the way.
