I've followed instructions of BrashMonkey's videos.
but i cannot import sprite sheeted animations into the project.
there are three files (animation.json, animation.png, animation.scml)
in c2, I dragged and dropped a single .scml file into the project, than opened a .png file into .scml object, but nothing happened.
in c3, I even cannot drag and drop a .zip file(contains png, scml and json) at all...
its so frustrating.
