How to Code: Galactic Light Trails

Getting a galactic light trail effect isn't achieved by rotating particles individually-it's actually created by rotating a canvas as a whole. With a few tweaks to rotation, opacity fills, and object randomness, we can create an eye-catching effect that emulates a time-warp in space.

I don't know why such high level content don't get views on RUclips,

[@armandsalle8447]

Nice to see you back on RUclips ! 🔥🔥🔥

[@ChrisCourses]

Armand Sallé thank you bro, hope to see more of your sweet canvas creations on Twitter!

[@johnadriandodge]

Really good stuff Chris! Thank you kindly!

[@serjmarkelov9915]

Thanks man! I've never meet such a useful content yet, really happy I find you :)

[@alishata8]

Best series on canvas I've ever seen!

[@chirilcugureanu1853]

So cool Chris. I'm happy you came back on YT. Stay safe and good look!

[@aleksandroff2757]

Thanks ! It is very interesting to study canvas with your tutorial!

[@theman7050]

You are working so hard to make something as complex as this so easy :D

[@kienboy9999]

painfully underrated

[@konradchyrzynski3927]

Wow, good job! :)

[@LN-rz5eg]

Thank you for the great tutorial! Is there a way to affect the previously created particles to make their shadow radius narrower as the new circles get created in order to create a fading effect?

[@dominikdeimel9486]

Great video! I really like the canvas tutorials!
But can you please close the sidebar in sublime so that your code doesn’t break so creepy and is a bit better readable?

[@ujjalkhadka]

I was wondering when you would teach us.. I tried few months ago after visiting your website, but I tried in a tilted way... more like a 2.5d not 2d and was stuck in between.. so as always, the project never got finished..
Thank you for this tutorial man. Hope you show us how you did that perlin noise of yours...

[@abdoseadaa]

you are more like davinci but with js , great as usual

[@gektorix]

Now it's time to try my hand at making games based on your guide.

[@elitegaming7903]

can you explain why reducing alpha makes those trail effects?

[@danielwestlund9208]

Great tutorial! I get an error from chrome dev tools about not using document.write() , anyone know why?

[@assimez-zaky8363]

Document.write just block any other dom from being generated

[@luischinchilla-garcia4840]

Will definitely sub to your site!

[@ChrisCourses]

Thank you homie, going to be the main job instead of the side job soon enough with your help 🤩

[@luischinchilla-garcia4840]

@@ChrisCourses Quick question on that: do you think you'll ever do Nuxt/Firestore related content??

[@ChrisCourses]

Luis Chinchilla-Garcia nuxt for sure, it’s my favorite framework by far, and pretty much the only thing I use for professional web apps. The web app course for beginners actually makes use of it a lot, but I’ll def get a singular intro course up here eventually

[@veliea5160]

how can I apply this to react.js? or can I apply?

[@assimez-zaky8363]

I believe you can use states instead of vars
