♢Thanks to @Griffpatch for the platformer tutorial, which I heavily modified to make it a scrolling engine.♢ 2020 update: This is outdated, when I made it I didn't even realize Griffpatch had an actual scrolling platformer tutorial. This is not the same as my previous mobile engine, it's a brand-new one that actually has better physics.
