Scratch 'When Green Flag Clicked' Examples: Basic Animation for Kids

📚 Quick Study Guide

• 🟢 The Green Flag: The green flag in Scratch is your project's "start" button. Clicking it initiates the code attached to the 'when green flag clicked' block.
• 🎬 Event-Driven Programming: Scratch uses event-driven programming. The 'when green flag clicked' block is an event handler, meaning it waits for a specific event (the green flag being clicked) before running the code.
• 🐱‍👤 Sprites and Scripts: Sprites are the characters or objects in your Scratch project. Scripts are collections of blocks that tell sprites what to do.
• 🎨 Basic Animation: You can use the 'when green flag clicked' block to trigger a series of motion and appearance blocks, creating simple animations.
• 🔁 Loops: The 'forever' block can be combined with 'when green flag clicked' to make animations that repeat continuously.
• ⏱️ Timing: Use 'wait' blocks to control the speed of your animations.
• 💡 Troubleshooting: If your animation isn't working, check that the 'when green flag clicked' block is properly connected to the rest of your code.
