For my side-scroller, I worked in a team on a game called Bob Ross Doing Everyday Normal Bob Ross Things. I mostly worked on the side-scrolling elements and putting the assets into the game, while my teammate found the assets and helped with the design process. To make the side-scrolling work, I had to have the background be a sprite, and when the arrow keys are pressed to move, the background moves instead. When the background is at a certain x coordinate, it stops moving and the sprite moves instead. I only managed to fit in one variable, which controlled the health bar, but I didn’t have time to make it work.
