Level 2: Don’t Fall In

Official Raspberry Pi Project

This lesson is based on the official Raspberry Pi Foundation project. Open it alongside this guide to access the starter project, step-by-step instructions and community remixes.

How to use it: Click the link above, then click See Inside on the Scratch project to explore the finished version. Use Remix to get your own copy to edit.

What You Will Build

Create a game where a sprite must avoid falling into danger zones.

What You Will Learn

By the end of this project you will be able to:

• Use Events blocks to start scripts and respond to clicks
• Combine Motion, Looks and Sound blocks to create behaviours
• Use variables to track game state and scores
• Apply the specific Scratch concepts introduced in Level 2

You Will Need

Step-by-Step Guide

1. Choose a dangerous backdrop: lava field, ocean, pit.
2. Add a player sprite on a platform.
3. Add platform sprites across the stage.
4. Use if touching [edge] and if y position < -150 to detect falling.
5. Add gravity: in a forever loop, change y by [-2] constantly.
6. When on a platform: stop falling using if touching [platform] set y velocity to 0.
7. Use arrow keys to move left/right and spacebar to jump.
8. Add change y by [10] for the jump with gravity pulling back down.
9. If the player falls off: play a sound, reset position.
10. Add a lives variable that decrements on each fall.

Extension Challenges

Try these after completing the main project:

• Add moving platforms that slide back and forth.
• Add collectible coins on platforms for bonus points.
• Add an enemy sprite that patrols certain platforms.

Reflection Questions
