Click the green flag. Up and Away you Go, with Scratch. Super Cat sails through the air, but the cat is not moving. Each building has code the make it move and come to the front or go to the back so the cat appears to be flying in front of some buildings and behind others. The cat, which is the main sprite, has no code. Click 'See inside' then click the thumbnail picture under the stage to see the code on each sprite.
This is the starter project in PART 1 (the Basics) Up and Away with Scratch when you start the course 'SCRATCH for Your Kids'.
