Now, as the buoy moves from left to right, it rocks as if floating on water. The flag and flag pole continue to sway. Adding damping effects Damping refers to how much the spring effect decreases with time. It wouldn’t be realistic if the rocking of the buoy or the swaying of the flag and the flag pole continues indefinitely. Over time, the swaying should lessen and eventually stop. You can set a damping value from 0 (no damping) to 100 (maximum damping) to control how rapidly these effects diminish. 1 Select the first bone of the buoy (in the floating part),. | Now as the buoy moves from left to right it rocks as if floating on water.

You can set a damping value from 0 no damping to 100 maximum damping to control how rapidly these effects diminish. 1 Select the first bone of the buoy in the floating part and in the Properties inspector in the Spring section enter 100 for the Damping. Tjr SPRING srrenglh zo Damci nq F f The maximum damping value will decrease the rocking of the buoy over time. 2 Continue to select each of the bones of the armature and enter the maximum value 100 for Damping. 3 Choose Control Test Movie in Flash Professional to see the effects that the damping values have on the motion of your buoy. The buoy and the flag and flag pole still sway but their motion quickly subsides after the initial starting motion and after the buoy stops at the far right side of the Stage. The damping values help add a sense of weight to the armature. Experiment with both the strength and damping values in the Spring section of your armature to get the most realistic motion.
