Interactivity is awesome — it’s what differentiates a Scratch project from a still image or a video, and is at the heart of all games. Condition is a question whose answer is “yes” or “no” or statement that is “true” or “false”
Create Scratch programs that solve some or all of the following interactivity puzzles
- Whenever you press the B key, the sprite gets a little bigger. Whenever you press the S key, the sprite gets a little smaller.
- When the sprite touches something blue, it plays a high note. When the sprite touches something red, it plays a low note.
- Whenever two sprites collide, one of them says: “Excuse me.”
