@kilopop Mine is not overly complicated… What I tried to do was extend skeleton to contain all the animation, images, etc to keep them in one structure. I also killed all that extra math and locked the animations into 30 or 60 FPS based on what the config.lua is set at… I figure if your animations can’t keep up you have bigger issues.
Finally I wrapped all the state events into one onEvent() but it should probably be renamed to onAnimation()
So I use it like this… Create a display object…
hero = display.newObject() physics.addBody(hero)
Then I create the spine as a metatable (or object) off of that display object
hero.spine = spine.new("spine/hero.json", { x=hero.x, y=hero.y, imageDir = "spine/heroParts", tetherObject = hero, mixTime = 0.25, }) hero.spine:play("idle",true)
Then I hide the original display object
hero.isVisible = false
I keep my spine runtimes in a package structure, so you’ll need to update the one spine = require()
Anything you can do to speed this up or improve the stability is appreciated.
