What is one of the most useful pieces of MATH every game developer should know? The Pythagorean theorem! Let’s use it to detect collisions. In this episode, we build a fully animated HUD and layered health bar, create a reusable collision system, and allow player to be damaged using event-driven logic. Let's make web games with vanilla JavaScript!
You’ll learn:
How to build an animated health bar with CSS variables
Event-driven game architecture using emitters
Circle-vs-circle collision detection
Why squared distance checks are faster than using square roots
Data-driven asset loading with map() and Object.values()
How CollisionManager and CollisionSystem work together
How to keep game.js clean and modular
Better ways to structure larger JavaScript game projects
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

Tiny details like hit reactions, UI animation, and sound feedback completely change how a game feels. Most games are really just layers of systems constantly communicating with each other in real time, so let’s learn how to build a flexible, reusable collision system for our 2D games.
This class is for beginners and intermediate developers interested in JavaScript game development, 2D game programming, and game architecture design. Whether you're building a top-down shooter, roguelike, survival game, or browser-based HTML5 canvas game, these techniques will help you create cleaner systems, better game feel, and more scalable code. We’ll work with vanilla JavaScript, object-oriented programming, collision detection algorithms, event-driven systems, reusable managers, and responsive UI effects commonly used in real game development workflows.

Lets take a look at CSS filters, specifically SVG turbulence animation (and displacement map) which apply perlin noise effect to any HTML element. It can also be applied to HTML canvas so you can try to combine it with any of the canvas effects we created in previous videos. Lets create really cool CSS3 creative menu hover effects also known as Squigglevision.
I have used CSS filters before to create sticky liquid effect. To achieve that we first blur the elements and then we apply strong contrast to make the famous flowing goo effect.
Today I will show you how to rapidly iterate between 5 distortion states using turbulence and displacement map inline SVG filters and how to tweak the effect to create your own variations
There is a patented cartoon animation technique called Squigglevision and we will recreate it with CSS. It was used for shows like Dr Katz and it is a computer animation style, that is supposed to remind viewer of hand drawn animation sketches. It is characteristic by shaking squiggly lines even when the characters are standing still.
Squigglevision cartoon technique is much faster to produce than hand drawn animation, because its made using computer. The shaking lines are done by looping 5 slighly different images over and over.

Code along with me and gain skills to get your first job in the industry. If I could do it you can do it too. If you decide to code along and modify the effects, share your Codepen/JS Fiddle in the comments, I want to see what you came up with.
My name is Frank, Im a self-taught Front End Web Developer. I learned everything I know in my free time and I used the knowledge to get a great job in web development industry. The part I enjoy the most is building creative animations and interactive effects for the web using HTML, CSS and JavaScript. Thank you for watching my video.

![JavaScript project tutorial for beginners [HTML Canvas Particles]](https://i.ytimg.com/vi/nrJh8-Ixnu8/mqdefault.jpg "JavaScript project tutorial for beginners [HTML Canvas Particles]
Do you want to bring your website to life? In todays JavaScript project tutorial for beginners I will take you through a step by step process on how to create your first particle system on HTML canvas element. We will give particles physics (wind and gravity) and we will learn how to make particles bounce. Then in the second part of this tutorial we will set up collision detection with a regular website element, for example h1 title element, but it will work with any HTML element you choose.
Welcome to my JavaScript laboratory where we practice HTML, CSS and JavaScript to create all different kinds of interactive animated effects. That includes games, generative art, webdesign elements and much more. In each JavaScript tutorial I take you step by step through the code base as we build our project from scratch.
And thats not all, we dont use any libraries or frameworks so not only we build cool stuff, but in the process we also learn fundamental JavaScript techniques. These techniques are completely transferable to other kinds of front end web development projects and will help you to pass your coding interview and get your first programming job.
My name is Frank and I am a self taught Front End Web Developer. I learned everything I know in my free time from structured Udemy courses and YouTube project tutorials just like this one. If I could do it you can do it to.

There are a lot of videos teaching you the basics of programming, but how are we supposed to learn some of the more interesting effects. Thats why I created this series, where we combine basic fundamental JavaScript techniques into creative coding experiments, generative art, games, animations for websites and more. For science of course:D
