Real-World Examples of Parameters in Scratch Animations

📚 Quick Study Guide

• ⚙️ Parameters are inputs that you can pass into a custom block in Scratch.
• 🧩 They allow you to create more flexible and reusable code.
• ➕ Parameters act like variables within the custom block.
• ✏️ You define parameters when you create a custom block.
• 💡 Using parameters makes your code cleaner and easier to understand.
