Bonjour et merci pour cette découverte de JavaScript avec ZTXT ! You are explaining very well this programming language, even in english. I'm french and I have fast all understood. ZTXT is an interesting IDE. We have the result of each line we write. Very well to study JavaScript and HTML Thank you !!!

[@NickNickSr]

YOU MADE THE BEST TUTORIAL FOR JS ANIMATION THAT I HAVE EVER SEEN, AFTER SEARCHING A LOT OF VIDEOS AND SITES!!!! YOU ARE THE MAN! THANK YOU SOOOOOO MUCH!!!!

[@RedFlagMobileDotCom]

Hey Mr. Z-- thanks so very much-- I feel like i learned more in that 20 minutes than I learned in the last 20 months. You are excellent && kind regards, mark-p. :)

[@KirklandsKnowBest]

You are the gooooooat. This helped me finish my assignment and understand fundamentally how the functions work

[@whatmargauxdoes]

An incredibly clear tutorial. Thank you! I Needed this for a class project.

Nice lesson. I also like the sound effect of the video.

[@sweethomes674]

Excellent explanations 😊

[@thegeorgepi]

Thank you so much. Best tutorial on this I've seen on this topic!

[@thegeorgepi]

Gonna reply to myself... Man. This was the first video of your's I watched and I was really excited, hoping you'd have hundreds of them like a bunch of the other guys who do tutorials on KZbin. Your way of explaining it and simplifying it is just incredible. I wish you would do more.

[@Anothergames]

Fantastic explanation! I would suggest showing the coordinate system as how it works with the canvas. Also, which book would you suggest to learn the canvas?

[@enginegod7537]

Hi Could you give me an idea on how i could create a canvas to be able to color different selected design on a web page? (example: same as if i would use a Crayola on a color book..) Thanks for the response Regards!

[@javierguerrero9486]

How do you even know all of those properties and methods for that particular objects from the canvas element?

[@susanhughes308]

How do I get a list of the functions that I can use with HTML5 canvas? LIke the function for bezier curves, for example? Please let me know. Thanks!

[@Itsme-gi1es]

Thank you for the video.anyone know how to drag a shape in canvas?

[@zevanrosser]

it depends on the kind of shape - boxes are easiest to drag - more complex shapes take a little more work

Ya its good thanks.

[@dancunchiriga]

Goodness i just asked the question before reading........:)

[@ezamavaughan3730]

what text editor do you use +Zhirayr Shirinyan

[@zevanrosser]

+Ezama Vaughan its called "ztxt" just google ztxt to get the github page and you can download it etc...

thanks

[@mdriyazuddinkhan]

thanks bro.

[@PheonixPhoenix101]

This small function converts degrees to radians if it helps anyone function degree2rad(degree) { return Math.PI * degree / 180; }

[@zevanrosser]

thanks for that... yeah I used to use that conversion a great deal - but at some point (many years ago) I just started using radians almost across the board because I got so used to them... I do use that when working with other programmers or - when specifically dealing with certain kinds of rotation... the fact that canvas doesn't have a simple `circle` function is stupid imo... still can't believe it all these years later... no circle function :/

[@PheonixPhoenix101]

@@zevanrosser To be honest, I really don't use canvas to often. I find the canvas API a bit quarky. I watched your video because I needed a refresher on canvas and your video is probably the best out there. I'm writing a function that tracks user interaction on a web site that uses canvas to display user activity over time.

[@zevanrosser]

@@PheonixPhoenix101 well, that sounds like a fun use a canvas at least. Thanks for the kind words :D

[@PheonixPhoenix101]

@@zevanrosser the function is driving me nuts. I get movement coordinates but I'm using time out instead of Interval to control the draw speed on the canvas but results are out of wack lol I actually want to shoot myself. I can't, for the life of me, figure out what's wrong.

[@zevanrosser]

@@PheonixPhoenix101 oh yeah - that stuff can be annoying - read up on `requestAnimationFrame` it's what people generally use now (~60fps = ~15ms interval)... or just use `setInterval`

[@simohamzaoui3164]

I should develope a method where you can just type cercle(x,y,r); do you guys wanna contribute ?

[@fengya2284]

i want to know your editor, what it is? thank you

[@zevanrosser]

its an old editor I created its still available though if you google "github ztxt" note the instructional video on how to get set up

thanks :-) !!

[@ren642653]

What mac are you using?

[@radouanebenmoudetter392]

how to download this

[@emilioaranda1434]

what if i put '3d' instead of '2d'???

[@clairecalloway6246]

I think you would need to use webGl

[@emilioaranda1434]

what is webGI?

[@JoelSjogren0]

Emilio Aranda According to www.html5canvastutorials.com/tutorials/html5-canvas-element/, there is only "2d" for 2d and "webgl" for 3d rendering.

[@clairecalloway6246]

webGl is a Javascript library to render objects in 3D using canvas. So instead of putting "2d" you would put "webGl" www.chromeexperiments.com/webgl/

[@dominicvelasco1756]

what's the name of the software?

[@zevanrosser]

there is a link in the description- its called `ztxt` - it is quite old though - and could really use an update - I still use it for lots of stuff - but it has some annoying quirks as a result of browser updates :/

[@dominicvelasco1756]

I see. Thank you for the reply :)

[@HdRFan7]

What editor is that?

[@HdRFan7]

***** Oh true :D didnt see it :/ Thanks!

[@zevanrosser]

yes just google ztxt to get the github page and you can download it etc...

my comment

[@mamerdimon]

pye no funciona el canvas

[@twilighttucson2526]

Welp... another beginner's tutorial (not intermediate) on canvas that is like every other pence introduction to it. All of these mind numbingsimilar tutorials are starting to run together. What about saving the canvas contents as an image? What about requestanimationframe? What about tying an event to an object that reflects on canvas?

[@zevanrosser]

+twilighttucson yeah this is an old tutorial - I might do a newer one - canvas had changed a good deal in the last few years

[@karinahulka1486]

waiting for it)

[@ZIMLEARN]

The canvas, or perhaps more specifically, libraries to help with canvas have advanced. ZIMjs is based on CreateJS but gives lots more like one line drag and drop, multiple hit tests and components. There are many tutorials in the Learn section. Hope they are helpful.

[@freedom-P]

It didn't work... I went through the entire video 2 times and I didn't see any mistakes... Why did it work for everyone else :(

[@zevanrosser]

if you paste your code here - I'll take a look - its probably a simple typo

[@freedom-P]

Ok btw I only have up to the black square I stopped cuz it wasn't there

[@freedom-P]

Just gimmie a sec

[@freedom-P]

Here:

[@freedom-P]

window.onload = function (){ var canvas = document.getelementbyid("paper"), c = canvas.getcontext("2d"); c.fillstyle = "black"; c.fillrect(0, 0, canvas.width, canvas.height); };

[@mamerdimon]

oye no funciona
