Hi Jack,

Thanks a bunch for the advice, I did it now this way:

import com.greensock.*;
import com.greensock.plugins.*;

TweenPlugin.activate([ShortRotationPlugin]);
TweenMax.to(mc, 1, {shortRotation:{rotation:210}});

Denny, that actually has nothing to do with TweenMax – it’s just that Flash ALWAYS reports rotation values between -180 and 180. So let’s say you start at rotation:0 and you rotate to 225. That’s a total of 225 degrees that it changes during the tween. Now when that tween is done, TweenMax did in fact set rotation to 225 BUT Flash will report the rotation value as -135! You can reproduce this without TweenMax, like:

mc.rotation = 225;
trace(mc.rotation); //reports “-135″!

TweenMax.to() always tweens from the current value to the destination value (of course). So if you tween mc again to 225, TweenMax will say “okay, what’s the current value?” and it will get back -135. So that tween will go from -135 to 225 which is 360 degrees!

You can use the shortRotation plugin so that TweenMax always plots the SHORTEST direction to the new rotation value. That way, in your scenario it would stay still on the 2nd tween. See the Plugin Explorer for an interactive example.

Hi,
is it meant that there is differenced between 180 degr ?
How can I fix that?

e.g. try the example above with with rotation:45 and rotation:225
anf hit the button “Tween” some times.
45 -> 1 rotation and than stop
225 -> always rotating 360 degr

nevertheless NICE work guy
