Here is some platformer code so you don't have to make any!If you are confused on slopes,this is the code for you!You can add this in any of your projects although,the wall jumps are not that good.Whenever you do a wall jump,the player will just rise up. You use arrows to move,you could add WASD to your project if you'd like. If you want to add this to your project,click "see inside'' ,open your backpack,and drag the player into the backpack.
I did not do this all by myself.I learned this from a tutorial on how to make an advanced platformer. And believe me,this is better than any of my previous platformers lol. And here is proof: https://scratch.mit.edu/projects/758573161/ Yep,it SUCKS
