I've made two movieclips of a cat's walk cycle, one walk left, the other walks right.
There is only one cat visible on the screen at a time, the other is invisible, having a alpha of 0.
I have also made up a movieclip which behaves like 2 play buttons, to play the two cat movies, and all this works fine. When then one walk cycle finishes, it just moves the the next keyframe, and the cat can walk in the opposite direction.
The problem is that to make my walk cycle more realistic, I wanted my cat to be able to turn around at its current _x position, so that it turns around/swaps to the other movieclip, and continue
