Scratch Jr. Simple Input Examples: Moving Characters with Taps

📚 Quick Study Guide

• 🖐️ Tap Event: In ScratchJr, tapping a character can trigger an action. This is done using the 'Start on Tap' block (the yellow block with a finger).
• 🧱 Programming Blocks: Use blocks like 'Move Right,' 'Move Left,' 'Grow,' or 'Shrink' to make your character respond to the tap.
• ➕ Chaining Blocks: You can connect multiple blocks after the 'Start on Tap' block to create a sequence of actions. For example, move right, then grow, then say something.
• 📍 Coordinates: Remember that ScratchJr uses a grid system. Moving right or left changes the character's horizontal (x) position.
• 🔁 Loops: While simple taps usually trigger a one-time action, you *can* use repeat blocks *within* the tap event to create simple animations.
• 🎨 Customization: Change the character's appearance and sounds to add more fun to your tap interactions.
• 💡 Troubleshooting: If your character isn't responding, double-check that the 'Start on Tap' block is correctly connected to other action blocks.
