Tweening with action script +/- from a set location
I know the basics of tweening with action script but I have a picture set in the center of the stage at x = 50. On a click I would like that picture move - 10 x from that position so it will end the tween at 40. On a different button I would like to do the oppositie, + 10 x to its current position so if it was at 40 it would be back to the start and if it was at the start it would be at 60.
Thanks
