 <p>The best practice here would be to use two different stages.</p> <p>Using two stages will simplify design in sense that the viewport management for 2d animation will simplify by a considerable amount. Also the event handling has to be completely different style. Your information panel won't have much relative layout changes in actors as compared to 2d animation.</p> <p>Using same stage would make sense only if both contents overlap each other in some form. I'm sure this is not the case here. Your info panel will always be ABOVE animation (most probably).</p> <p>Hope this helps.</p>
