I haven't done much game development stuff, because my job as a web dev and preparation for entering college have been taking most of my time in the past few months. I couldn't find a tutorial about how to render a camera which focuses on the character for my 2D RPG, so I coded it myself with PyGame one free afternoon. I needed to store the entities' world coordinate, and calculate their screen coordinate based on the character's world coordinate. It was fun, drawing the logic on a piece of paper and wrote the code right away. It's nothing big, but I'm kinda proud about it. I still need to learn so many things.
