Thankyou!
It is not so much inside a game itself that I will be using the Widget, rather, just in spaces where a user's character will be seen by itself in a basic idle animation with next to no interactivity. (These will be most often seen next to forum posts to represent a user as an avatar or a public facing character sheet outside the game with some stats, etc.) With each user having their own json file (or, that's the plan right now, anyway), the site will be able remember each user's character's equipped clothing parts (or I could store this data elsewhere and make it render these parts dynamically, but I want to try Widgets with multiple json files first). I'll test a few things for speeds sake.
I've seen similar setups out of Japan use Flash but I wanted to try something new with just Canvas that won't require third party plugins that don't render well or at all on mobile devices. :coffee: Spine should be really great for this.
