Since the “Tutorial” section on this forums requires that the tutorial is actually within the topic, I’ve decided to post the link here.
I’ve created (and continue creating) videos showing the whole process of writing a game engine for a generic Platformer - open source of course. I’m using libGDX for rendering (OpenGL under the hood) and Entity Component System for the game logic binding.
