Scratch Lessons:
Jumping and Platforms 1. Now that both our backgrounds and character move, it’s time to program our character to jump. There are many ways to do this, but in our method we will begin by painting the bottom of our character’s feet red. You must do this for each costume.

Click on your first background and drag the whole block of code onto your first platforms.
Drag the whole block of code
* Repeat steps 5 and 6 for more platforms, except drag the code from your next background onto your next set of platforms. For example, for your second set of platforms, drag the code from your second background onto it:
