Space Invaders with JavaScript and HTML Canvas by Christopher Lis

Ready to build your own retro arcade hit? This course dives into coding a Space Invaders game from the ground up using JavaScript and HTML Canvas. You’ll learn all the core mechanics, from player movement and shooting to enemy waves and power-ups, all while understanding the underlying math and logic rather than relying on pre-built libraries. It’s a fantastic way to boost your game development skills and create a portfolio-ready project.

🎯 What you’ll learn

• Set up a development environment for game coding.
• Create and control a player spaceship.
• Import and use game graphics.
• Generate and manage enemy grids.
• Implement projectile shooting and enemy destruction.
• Detect collisions accurately.
• Add explosive bombs and power-ups like machine guns.
• Increase enemy difficulty over time.
• Create particle animations.
• Develop a game UI with HTML and CSS.
• Implement start and end screens with restart functionality.
• Integrate custom sound effects and music.
• Ensure consistent frame rates for smooth gameplay.
• Deploy your game to GitHub Pages.

✅ Requirements

• Skills: Basic understanding of JavaScript principles (variables, loops, functions). Some familiarity with HTML canvas is helpful but not essential.
• Tools: A web browser and a code editor (like VS Code).
• Hardware: A computer capable of running a web browser and code editor.

📝 Description

This course is a hands-on journey into building a classic Space Invaders game using JavaScript and the HTML Canvas element. You’ll go beyond just copying code; you’ll learn the fundamental programming concepts that drive game development, often by implementing mathematical functions yourself. This approach gives you a deeper understanding of how games work under the hood, which is invaluable for tackling more complex projects later on.

The instructor, Christopher Lis, breaks down the process step-by-step, starting with setting up your development environment and moving through player controls, enemy AI, shooting mechanics, and collision detection. You’ll also add exciting features like power-ups, explosions, particle effects, and even integrate sound and music. The course culminates in deploying your finished game, making it accessible online. It’s designed to give you a solid foundation in 2D game development with web technologies.

🧑‍🎓 Who this course is for

• Beginner game developers looking to build practical skills and understand core game development concepts.
• Web developers wanting to expand their skillset into game creation using JavaScript.
• Anyone interested in recreating classic arcade games and learning frontend development in a fun, project-based way.
