Simple coding examples: Connecting blocks to make things move

📚 Simple Coding for Movement: Quick Study Guide

• 🧱 Connecting Blocks: In visual coding environments like Scratch, you drag and drop blocks to create scripts.
• ➡️ Movement Blocks: Blocks like "move [number] steps" or "change x by [number]" control an object's position.
• 🔄 Looping Blocks: "Forever" or "repeat [number]" blocks make actions happen continuously or a set number of times.
• 🕹️ Event Blocks: "When [key] pressed" or "when flag clicked" start scripts based on user interaction.
• 🧭 Direction: Objects have a direction (0-360 degrees) that determines where they move when using "move" blocks.
• ➕ Coordinates: The stage uses x and y coordinates. Changing x moves objects horizontally; changing y moves them vertically.
• 💡 Tips: Combine different blocks to create complex movements. Experiment with different values to see how they affect the object's motion!
