Data-Driven Particles: More Effects, Less Code
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: • Vanilla JavaScript Game Development Course
