I was in the same boat a few years ago. I started programming in the Starcraft 2 editor, which allows you to basically create anything from a mini-game to a custom campaign for the game’s library. I had absolutely no idea what I was doing . I managed to make a few hashed-up projects by watching step-by-step tutorials.
First thing’s first, programming in any computer language takes dedication and a lot of time to get good at it (Which, I mean, what art doesn’t ). I’m still no good at it because I only recently started getting serious about it. There’s nothing specific, but take a look at these tutorials https://www.defold.com/tutorials/, especially the platformer, side scroller, and runner in your case to see what you’d like. Once you’ve learned enough, you can actually pull different aspects from each of those to create a Mario-like game.
Absolutely! It’s weird to get used to, but, once you create a project on the dashboard, you can use “Open project from disk” to do so. Then it will appear in your “Recent Projects” list to make it easy.
Ah @britzl, you beat me to the welcome committee.
