How to Make a Geometry Dash Game on Scratch: A Step-by-Step Tutorial

Introduction
Geometry Dash is a popular rhythm-based platformer game known for its challenging obstacles, vibrant visuals, and addictive gameplay. If you’ve ever wanted to create your own version of Geometry Dash, Scratch—the block-based coding platform—is the perfect place to start! In this guide, you’ll learn how to make a Geometry Dash game on Scratch using simple coding concepts, sprites, and creative level design. Whether you’re a coding newbie or a Scratch enthusiast, this tutorial will walk you through every step.

Prerequisites
Before diving in, ensure you have:

  1. A free Scratch account (scratch.mit.edu).

  2. Basic familiarity with Scratch’s interface (sprites, blocks, stage).

  3. Creativity and patience!

Step 1: Set Up Your Scratch Project

  1. Create a New Project: Log into Scratch and click “Create” to start a new project.

  2. Choose a Background: Geometry Dash features colorful, geometric backdrops. Delete the default cat sprite and pick a background by clicking the “Choose a Backdrop” icon. Search for “grid” or “neon” for a retro vibe.

  3. Rename Your Project: Click the title field and name it “Geometry Dash Scratch Game.”

Step 2: Create the Player Character
The player (often a cube or ship in Geometry Dash) will navigate through obstacles.

  1. Design Your Player Sprite:

    • Click “Choose a Sprite” and select a simple shape like a square or triangle.

    • Use the costume editor to color it brightly.

  2. Code Movement and Gravity:

    • Add these blocks to the player sprite:

      when green flag clicked  
      forever  
          if  then  
              change y by (10)  
          end  
          change y by (-2) // Simulates gravity  
      end  
    • Adjust the gravity value (-2) to control falling speed.

  3. Limit Movement to the Screen:
    Prevent the player from moving off-screen with:

    blocks
    Copy
    if  [180]> then  
        set y to [180]  
    

Step 3: Design Obstacles and Platforms
Geometry Dash challenge comes from avoiding spikes, gaps, and moving blocks.

  1. Create Obstacle Sprites:

    • Design spike shapes or use the sprite library’s “Bat” or “Block” assets.

    • Place them along the stage to form a basic level.

  2. Add Movement to Obstacles (Optional):
    Make obstacles move horizontally for extra difficulty:

    when green flag clicked  
    forever  
        move (5) steps  
        if  then  
            turn around (180 degrees)  
        end   

Step 4: Implement Collision Detection
The game ends if the player hits an obstacle.

  1. Code a “Game Over” Message:
    Add this script to the obstacle sprites:

    blocks
    Copy
    when green flag clicked  
    forever  
        if  then  
            broadcast [game over]  
        end  
    end  
  2. Handle the Game Over Event:
    In the player sprite:

    blocks
    Copy
    when I receive [game over]  
    stop [all]  

Step 5: Add Level Progression
Geometry Dash levels auto-scroll to the finish line.

  1. Create a Scrolling Effect:

    • Make the background or obstacles move left to simulate forward motion.

    • Attach this script to obstacles:

      when green flag clicked  
      forever  
          change x by (-5) // Adjust speed here  
          if  then  
              hide // Remove off-screen obstacles  
          end  
      
  2. Design Multiple Levels:

    • Use backdrops to represent different levels.

    • Switch backdrops when the player reaches a certain x-position.

Step 6: Polish Your Game
Enhance gameplay with music, effects, and a start menu.

  1. Add Sound Effects:

    • Import a soundtrack by clicking “Sounds” > “Choose Sound.” Search for “8-bit” or “electronic” music.

    • Play the sound when the game starts:

      when green flag clicked  
      play sound [sound name] until done  
  2. Include a Start/Reset Button:

    • Create a “Play” sprite. Use this code:

      when this sprite clicked  
      broadcast [start game]  
  3. Add Visual Effects:

    • Make obstacles flash on collision:

      when I receive [game over]  
      set [ghost] effect to (50)  

Step 7: Test and Share Your Game

  1. Test Frequently: Click the green flag to check for bugs. Adjust obstacle speeds or gravity as needed.

  2. Share on Scratch: Click “Share” to publish your game. Add tags like “Geometry Dash” and “platformer” for visibility.

Conclusion
Congratulations! You’ve just built a Geometry Dash-inspired game on Scratch. By mastering movement, collision detection, and level design, you’ve taken a big step into game development. Experiment with new features—like power-ups or custom animations—to make your game unique. Don’t forget to share your project with the Scratch community for feedback!
