The script that says [if touching color green] [set y velocity to 1] causes the sprite to shake a little bit when it touches the ground. If a sprite gets stuck in the middle of a platform, this script causes the sprite to slowly rise to the top of the platform. If you change the [set y velocity to 1] to [set y velocity to 0], you can avoid this.
Thank you for looking at this tutorial. :D BTW, use the little white arrow in the bottom-right corner to go to the next page, and use the white arrow in the bottom-left corner to go back a page. If you can't see one of the arrows, it means that you are at the first page or you are at the last page. Update: 1000 views! Thanks everyone!
