Let's build awesome animations that will work in any browser and on any website. In this vanilla JavaScript and HTML canvas tutorial we will learn A LOT about image manipulation and create many cool effects including 'pixel fire'. At the same time we will learn about important JavaScript techniques, that can help us to pass coding interview and get hired as a junior Front End Web Developer. In this tutorial we will add more tools to our vanilla JavaScript coding toolkit and I will show you how to create different animations using pixels from an image.

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.

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 3 жыл бұрын

@@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.

@@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

@RobertWildling Жыл бұрын

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 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.

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

@JM-de2gh 3 жыл бұрын

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 3 жыл бұрын

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 3 жыл бұрын

@@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.

How to export the code as video?

@MsSomeonenew 3 жыл бұрын

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 3 жыл бұрын

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.
