@iliazeus nope, the graphics (frames, MovieClips, buttons, etc) are separate from scripting. You *can* draw programmatically from ActionScript, but things you draw in the editor are represented more like SVG or Lottie.

I haven't read the format spec, but if you need proof, look at the failure mode of Ruffle when it encounters something unimplemented. Still draws the frame, just doesn't react to anything and gets angry in logs.
