I just found a blog http://monkeygameprogramming.blogspot.it full of source code for MonkeyX (at the moment there are 38 examples ).
Some are very simple (a sort of introduction to the language) other more ‘useful’ for a game-oriented programmer (always very easy to learn!)
I appreciate the fact that every single example doesn’t need any external resources (at the moment): no graphics, no sounds etc.
You just copy and paste the code in your IDE and compile it.
The focus is the source.
