Go into the project and it will teach you to use a scrolling platformer. Make sure to give credit to @0rangie-Fr3sh and @griffpatch if you use it. :D *Notes and Credits* @griffpatch for his tutorials, I just did them and made it so it is easier to use it. Also if you need a platforer engine use this one, it is very good: https://scratch.mit.edu/projects/491691290/
