ct.js v2 is out 🎉


Better. Smarter. More powerful. Ct.js v2, after almost a year of development, is finally out 🎉 This update makes a groundwork for a more efficient evolvement of ct.js, and also brings a ton of new features and improvements.

It has experimental mobile export support, free asset gallery, asset grouping, translatable catmods, new UI themes, new documentation articles, ct.pointer as a successor to ct.mouse and ct.touch, and yadayadayada.

I will probably make a video with highlights tomorrow, and will need to upload packages to Github as well. Right now, I need to sleep 😴

Note that this update brings a bunch of breaking changes. Please see this migration guide to see what changed and what needs updating from your side.

If you’ve updated ct.js to v2 by mistake, you can still download previous releases here.

If you face any issues, write to our Discord server or file an issue on Github (links below).

I Already Have Many Game Project In This Engine... Seeing This Engine Have An Update... It's Hype Me Up...

Also That Export To Android Feature... I Wanna Try It...

Good Luck On Developing This Engine... :3.

Oh WOW!!!

I still remember trying out Ct.js 3 years back (if I’m not wrong it was 0.3.0). I got busy with a project and lost touch with this engine. Today I was searching for something and found your post and was going through the list of new and existing features I’m like this => 😲.

Good job.
