Visual programming language Catnip! Plus better bitmap font support, Typeface asset type, and more!
The main feature of ct.js v5 is Catnip — a block-based visual scripting language, made specifically for ct.js. It functions similarly to Google Blockly or Scratch, but better, and can do everything other languages can do! Documentation received a new section called Learn Catnip, and tutorials have Catnip code blocks alongside JS and CoffeeScript ones, too.
Besides that, we updated the way ct.js handles fonts — Font assets turned into Typefaces, and Typefaces can house several font files for different weights and styles in one asset for easier programmatic use. Issues with bitmap fonts rendering was fixed, and buttons and textboxes can now use bitmap fonts instead of canvas-based labels, which provides pixel-perfect rendering for pixelart projects. For individual labels, a new base class was introduced.
Ct.js v4 projects can be safely migrated to v5 — but make sure to update your text styles according to our migration guide: https://docs.ctjs.rocks/troubleshooting/migration-4to5.html
