If you have a child movieclip on stage with an animation in it, can you have the main timeline play the child movieclip at a certain timeline?
mc_child is a 20 frame animation with this.stop() at frame one so that it is paused at the beginning.
If you add the code this.mc_child.play() or this.mc_child.gotoAndPlay(5) you get an error in createJS. "Uncaught TypeError: Cannot read property 'play' of undefined."
How do you make child movieclips play at a certain frame?
You can use
gotoAndPlay(5);
