Create beautiful particle systems with HTML5, CSS3 and plain vanilla JavaScript, no frameworks and no libraries. Understanding how the code works will allow us to transform this codebase into multiple very different effects. Let's explore the basic techniques and then take them to the limits in this particle effects crash course.
Today we will learn:
🎨 how to make HTML5 Canvas projects fully responsive
🎨 how to detect and react to mouse events
🎨 how to calculate distance between 2 points and direction of push in a 2D space
🎨 how to add physics - acceleration & friction

I am so glad I found your channel. These tutorials are so thorough and well-explained. Thank you SOOO much!
Happy to hear, glad you found some value
Love these tutorials, thanks Frank.
Thanks for all your videos you make them super easy to follow and to code along with
Perfect as always
Thank you
Awesome work ❤
Wow, amazing video. Showing how atan2 calculates the angle was so important and you have done it so beautifully. Thank you!
Waiting for the optimization techniques video. Please do make it. 🙏
Thanks a lot!! I'm totally in love with what we can do with Js thaks to your videos. I was able to follow along and achieve the same results.
Nice work! :)
Thanks Frank! excellent explanation, this is awesome how you visualized & explained every bit of code, especially part with trigonometry :) P.S. it is possible to make code a bit more touch-friendly by replacing all mouse events with pointer events, in order it to work nicely on touch devices too
Touch and drag events are very easy to implement, takes only a few lines of code. The more challenging part is everything else in regards to hellscape that is mobile phone browsers :D The only reason I don't do touch events on everything is that people would ask me to make it fully mobile compatible :D

Beautiful! Subscribed!
I imagine that letting go of the mouse you can trigger a gravity to pull back particles to the center of where the mouse was. Has the effect of putting your finger in a fluid, then taking it out the fluid rushes back and normilizes
Great idea, it wouldn't be so hard to implement, will try it now
@@Frankslaboratory I'm happy to hear :)
Would be cool to see that !
Btw I'm really inspired by your videos.
I'm a long time architect and BE dev, starting to work on my own projects, and studying up on FE. The fact that you're using canvas & vanilla js makes it so much easier to use anywhere I want :) so thanks a lot!
@@Frankslaboratory my current idea, which I'm trying to do, is a project dashboard. I'd like to have a zoomable (and navigatable w/ touch support) canvas, like a showcase or wallpaper of square images w/titles, the center square locked, and has a big "+" icon which will spawn a new square/project to the cancas.
I want to have background particles to bounce off all sides of the squares, something akin to how you bounce particles on html elements (but 0 gravity). The challenge is to be able to drag (and snap to grid) the project elements around, and moving the html elements with it, not sure how to accomplish that... Let me know if there's anything you can suggest 🙏
Thanks a lot and all the best!
Hello Frank, do you have something in mind for creating the opposite effect, for example collapsing text on a point?
Hi, I did advance particle text class, that code can be easily converted into text breaking into pieces that collapse into a point. For example you can suck the letters into mouse cursor etc. If I misunderstood let me know what exactly you are trying to achieve,
I would love to see how we can improve performance.
I share small performance tips as I code along, I will cover the more complex techniques as well
Thanks for the excellent video, it helps much and show me a exciting way to write code. By the way, i found a weird situation that if i dont invoke beginPath() before every connection lines was drawing , there will be a huge frame drop on screen. What I searched on Google didnt helps, and as a very beginner for canvas, i dont know the reason. I wonder if you can explain what happend ?
Hi. Begin path ends and the previous shape and starts a new one. Without beginPath you are drawing all circles as one massive connected shape in a single draw call. It will be noticeable on performance even if you have only 20 circles. I think it's because it's connecting all shapes together so the calculation is much more demanding. Or canvas is just not optimised for that because arc is supposed to be always called after beginPath
You describe exactly what happened to me. And I benefited a lot from your answer. Thank you once again.
es is wunderschoen frank, aaber alter is des kompliziert. i bin net so super in mathe - des wird gg ende immer zacher. dabei wuerd i sowas so gern machen
Hi, not sure if the translation is correct, are you saying it's too complicated because of the math?
@@Frankslaboratory hi frank, basically yes that was kind of my mental sigh, that my brain does not seem to be cut our for this mathematical approach for unfolding this kind of beauty. for some moments , i was under the impression, you might be german - this was why i bothered you with german, i am austrian. i love your work, it is so inspriring ! it's just, i wish it would be easier to follow that coding logic and mathematical causality. i'm too stupid, that's why i became architect and could never be a lawyer or a surgeon. sitting between rocks on the hard place, watching your generative beauty from outside ^^
Большое спасибо за видео, Фрэнк. Очень креативно ! Есть несколько хороших видео, обсуждающих физику частиц, такие как ниже. Это математическая тема, но математика - это весело, так почему бы и нет.

sir, please 😢 cloth simulation for your next tutorial 😊❤💋
