I've created a graphic symbol that includes a single shape and nothing else. Now I want to apply a motion tween to that shape inside the symbol timeline: I want it to wiggle back'n'forth so I can reuse that wiggling symbol many times on the main timeline.
However, the program keeps demanding that I make another symbol out of that shape before I apply a motion tween.
This just seems weird: having a symbol that includes nothing but a single shape, and then creating another symbol that includes nothing but that same shape just so I can nest it inside that first symbol and apply a motion tween to it. Just wanted to make sure that I'm doing everything right.
