JavaScript Pixel Rain with Colors 🎨

[@mayank_singh_43]

after failing in 4 attempts for this thing in my pc ,finally yesterday's night , i was able to complete this work 100%. I had made some modifications too. Thanks alot for helping me ,u are a legend ❤️❤️❤️

[@Frankslaboratory]

Hi Mayank! Congratulations on completing the project, sounds like you were dedicated to make it work. There are many modifications that can be done here, I could have made this video 3 hours long. thank you for your feedback ❤

[@ConorBailey]

Love this Frank. Awesome work! Love that it’s all done with plain old js as well. Nice one bud.

[@Frankslaboratory]

Hi Conor, thanks. I do everything on my channel with plain JS, it's kinda my niche and people seem to like it

[@minzcode]

That's a cool effect. I'm looking forward to the next tutorial.

[@Frankslaboratory]

Hi, I haven't checked your channel for a while but I can see you really levelled up your content. I really like your latest set of videos. Getting close to 1000 subs, awesome. If you decide to be on camera eventually in your videos we can do a collab tutorial :)

[@李坤霖-c7m]

I follow your videos and try to reproduce these effects myself, and I remember that clearRect function is important to call at every frame, which became my mindset. So when I inspected the code of step6 on codepen, I dont know what are the differences between the code and mine at first. After a while, I found a tip on screen showing "Dont Clear .. ", and when I commented the clearRect funtion, the result shocked me, and so did your programming thinking.

[@Frankslaboratory]

Nice. It's fun to combine different ideas like this. Sometimes I come up with unexpected results. Glad to hear you found some value

Hi, thank you, very kind to say

[@HoldenTudiks81]

I had no idea there was going to be more to the first video💙💙💙. I am so glad I don’t have to search and combine elements from 20 different sources to get the effect I want.. still planning to and my own touch to the project I’m working on. Thanks for making video tutorials like this because I’m a total audio visual learner.

[@Frankslaboratory]

There are many other things that could be done with this technique, I could have spent another hour playing with the code making new effects. Good luck with your studies Curtis

[@coltonaallen]

Another great tutorial! I love all the experimentation and how you show your process. I'm already beginning trying out these methods. Your videos are always the ones I wait most for to release. Thanks again!

[@Frankslaboratory]

Hi Arthur, I do this experimentation with a lot of my codebases but usually don't make it into a video. I'm not sure how valuable it is to people but I guess it does give some insight into certain techniques. This one was a bit special, people reacted and liked the original effect so I decided to release this as a bonus :)

[@coltonaallen]

@@Frankslaboratory I personally would like to see more the the thoughtprocess that goes into these projects. I think it's cool and refreshing to see that you're just experimenting with values as opposed to other tutorials where it looks like they've done it a million times and just throw some code up on the screen. We got to hear what you wanted to do, and then the process in which you accomplished said goal. I think this is exactly what new coders need to realize, myself included, is that there's a particular mindset that you have to have while problem-solving or coming up with a new project. Very cool to see, in my opinion.

[@Frankslaboratory]

@@coltonaallen I'm hearing your feedback, thank you for taking the time to let me know. I will show more behind the scenes when it fits the project. Some projects are more flexible than others. What I mean this video like this I can make many variations quickly, if it was a gamedev video, variations and experiments would most likely mean additional features, which take more code to implement. Maybe this experimentation part would also fit a live stream format, hmm. Now you gave me an idea :D

[@coltonaallen]

@@Frankslaboratory I would totally subscribe to livestreams! Although the 8+ hour time difference would be hard to catch, but I whole-heartedly support it. Lol. Keep up the inspiring work. I think I've learned so much about how javascript actually works through your tutorials without the need of any libraries. This fire variant has given me a great idea to try so I'm currently working on it.

[@chefbennyj]

I have been waiting to watch this tutorial! Thank you Frank. I've also been following along from your codepen. That fire effect is really really cool!

[@Frankslaboratory]

Hi Benjamin, thank you. I need to work on some optimizations now, have few ideas

[@Radu]

Cool! Any idea how CSS filters compare with Canvas filters?

[@JM-de2gh]

If you are talking about compositing images over images: CSS, Canvas, and almost any photo editing program has the same filters. Things like Additive, Subtractive, Multiply, Screen, Overlay, Lighten... etc. They each might use different words, but it's all the same principle. Here's a list of Canvas compositions: developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/globalCompositeOperation However, if what you mean by compare is 'processing and speed' - CSS filters will be more efficient to use over Canvas unless you are already using Canvas to achieve other effects, then it would be better to just use Canvas filters.

[@Frankslaboratory]

Hi Radu and Jon, this is really interesting discussion I love filters. The naming is slightly confusing because sometimes I use inline SVG filter and call it canvas filter as well, then we have as Jon says globalCompositeOperation from canvas 2d API, it's CSS counterpart is CSS mixed-blend-mode property. Then we have CSS filter property I used in this video and it's counterpart is inline SVG filter that is basically HTML mark-up applied via CSS using it's ID. I need to do a proper testing session with all these. The thing I used to create 'fire' effect is just filter I normally use for 'liquid' effect. filter: blur(2px) contrast(3). Sometimes I also use inline SVG mark-up to achieve the same result but in this codebase you get a completely different end result with inline SVG. I need to test this further to fully understand what's going on. Great question Radu thanks.

[@Radu]

@@JM-de2gh I was referring to what Frank does at 21:11 in CSS. I know you can also set blur to the context like ctx.filter = 'blur(2px)'; but not sure which I should use. I have a feeling that the CSS variant is faster.

[@Radu]

@@Frankslaboratory Yeah :-) too many technologies and way to accomplish similar effects.

[@ЕгорРура]

[@Frankslaboratory]

Hi Erop, nice to meet you, glad you found some value

[@RobertWildling]

Beautiful! - If you ever intend to make another video of this kind, I would really love to know how you would solve a kind of "fade out" effect, e.g. as button to stop the effect can be clicked; but then only those particles disappear, that are already disappearing, because they reached the edge of the screen. I could solve this only by implementing a method that splices the particlesArray as such, but not by splicing a "out-of-sight" particle (which would need indexOf, and that messes with the speed parameter, which will throw an error after the first removal already).

[@JM-de2gh]

Top notch stuff. I wish I had time to make tribute v2 for this (I have some ideas), but I really need to weary myself working on my portfolio for now.

[@Frankslaboratory]

Thanks Jon, I'm still enjoying the memory of the first tribute hahaha. Also the fact that we are calling it a tribute makes me feel super important right now :D :D What's the plan for your portfolio, are you going for visually impressive or clean and proffesional?

[@JM-de2gh]

​@@Frankslaboratory Although visuals have a special place in my heart -- I'm treating my portfolio like a business site where I'm the product. I'll stick to clean on this one. I'm trying to keep all movement or animations secondary and subtle. Now, on my projects that I demonstrate on there, I hope to showcase some visually interesting things.

[@Frankslaboratory]

@@JM-de2gh It does make sense. I guess also it is about what kind of jobs you are applying for. From my experience many front end hiring managers are creative people and they will appreciate if you include some neat animations, as long as you make sure it doesn't break mobile responsive styles and page performance. My advice would be make sure you have good accessibility score as well. Hiring manager check that.

The is gorgeous! Is there a way to render a HQ still frame from this?

[@Frankslaboratory]

Hi Ali. Canvas renders raster images. Its pixel based. To make it HQ you would have to make the entire project bigger so it contains more pixels.

[@Frankslaboratory]

Then taking screenshot is simple. In some cases you can just right click canvas and save it as png

[@gastonalejandrotrivi2944]

Im having a pretty horrible time with this one. Pc barely runs at 5000 particles. I take it my i5 w 4gb of ram doesnt cut it. Is there a way to make this work with relatively low specs? (without a whole course on node, im saving that for later)

Sir franks , can we add audio files in codepen ?

[@Frankslaboratory]

Hi tarun I think you need to have PRO subscription on Codepen to be able to store images and audio files on their servers, but you should still be able to link them from remote web accessible locations.

[@MsSomeonenew]

Constraining position1/2 with Min/Max to canvas size seem like a more straightforward solution then constant checking. And on my browser globalCompositeOperation increase processing demand 10x, so I'm not sure this is stuff to use on more general use websites as the end user might get a terrible experience.

[@Frankslaboratory]

Good idea with min/max, thank you for sharing. globalCompositeOperation and for example canvas shadows are very performance hungry, but I show it anyway, couple of years ago rotating image on canvas was very slow and now it's optimised and easy. I hope that as time goes on these features will be better supported and optimised, so we might as well learn some of them now.

[@kevintremerel2619]

Hi franck, i got one question, is that normal that the speed of particles is not linear, i mean there is like it goes slow and a bit fast then slow ..
