E.g. Could I extend the SpriteFont plugin with scripting, and add a scripting block that could essentially do a "load image from URL" for the SpriteFont (as this action currently does not exist)?
I have a few ideas like this, very niche ideas that probably wouldn't get far on the suggestions platform, but important enough to me that I'm willing to work hard to try and get these extra features in my project.
Develop games in your browser. Powerful, performant & highly capable.
You can subclass instances to add your own properties and methods. But this doesn't grant any new capabilities beyond what existing scripting APIs are provided.
Thanks so much for the pointer!
