Give your games more juice with particle effects! In this tutorial, we'll build a complete data-driven particle system that lets you plug in any future particle effects you can imagine. We're using vanilla JavaScript to build everything from scratch, so you can see exactly how it works under the hood. Game engines like Unity and Godot abstract much of this away for you, but understanding the underlying architecture will make you a better game developer no matter which engine or framework you use.

🎓 This is part of a full vanilla JavaScript game development series, where we’re building a reusable starter kit step by step: youtube.com/playlist?list=PLYElE_rzEw_tjnJ_5gzRw0ZM5HRn7AIS0&si=j53kz7v7JoN5dg1B

In this class we will learn:
How to make a particle system in JavaScript and HTML5 Canvas
How to make spark and smoke effects in JavaScript
How to organize game code so it's easy to extend
How to make different particles move in different ways
How to trigger effects when something happens in a game (like taking damage)
How to make particles fade out smoothly
How to make particles shrink over time
How to randomize particle color, size, and count
How to apply gravity to moving objects in Canvas
How to draw and animate lots of objects efficiently on Canvas
How to structure a JavaScript game so it's easy to add new features later

By the end of this tutorial you'll have a reusable particle framework capable of supporting everything from simple sparks and smoke to much more advanced effects later in the series.
