I wonder if this is a scripting system?
Its not. Sorry! Its a bunch of readymade objects, scripts and code snippets that allow you to easily create your own platforming game!
I understand, but can you explain to me how it matters to the game maker studio 2?
Im afraid I don't understand the question. Can you rephrase?
Ok,but how can i export these files to game maker studio 2?
They are already in game maker studio 2. It is a game maker studio 2 project, and you can simply look at and use the code.
Got it, I really liked it.
