Thanks for your help Bruce. Brad Carroll sent me the formula. the pendulum is swinging now: on animateMe angle = angleStart * sin(2*pi*f*t) x = cordLength * sin(angle) + centerH y = cordLength * cos(angle) + centerV newPoss = point(x, y) mySprite.loc = newPoss end animateMe f is the frequency t is the elapsed time centerH and centerV is where the pendulum is suspended ralf.
