Here is a project using move, glide, turn, point in direction, sounds, waits, broadcasts and loops. Press "go" to start the code and get a small tutorial. Then, review the code inside to see in detail how these effects are accomplished. Can you parse the code? Remix and add your own twists!
Check out my other project all about exploring how to make the ball roll: https://scratch.mit.edu/projects/333309427 (Note: The confetti effect is a bit more complex and uses clones and the random variable. Don't worry if you haven't learned those yet.)
