This tutorial is a pretty simple but very functional platformer engine. It features mobile, wall jumping, all collisions, and explains how everything works inside the “Player” sprite. Very simple but works well - 144 blocks only
So a few years ago I was using Griffpatch tutorials for this but they never worked. So I used some of the things he had but tweaked them so they still work. Please don’t follow me and follow @-KingMoose-
