/** * VERSION: 1.12 * DATE: 10/2/2009 * ACTIONSCRIPT VERSION: 3.0 * UPDATES AND DOCUMENTATION AT: http://www.TweenMax.com **/ package com.greensock.plugins { import com.greensock.*; /** * Identical to bezier except that instead of defining bezier control point values, you * define points through which the bezier values should move. This can be more intuitive * than using control points. Simply pass as many objects in the bezier Array as you'd like, * one for each point through which the values should travel. For example, if you want the * curved motion path to travel through the coordinates x:250, y:100 and x:50, y:200 and then * end up at 500, 100, you'd do:

* * TweenLite.to(mc, 2, {bezierThrough:[{x:250, y:100}, {x:50, y:200}, {x:500, y:200}]});

* * Keep in mind that you can bezierThrough tween ANY properties, not just x/y.

* * Also, if you'd like to rotate the target in the direction of the bezier path, * use the orientToBezier special property. In order to alter a rotation property accurately, * TweenLite/Max needs 5 pieces of information: *
    *
  1. Position property 1 (typically "x")
  2. *
  3. Position property 2 (typically "y")
  4. *
  5. Rotational property (typically "rotation")
  6. *
  7. Number of degrees to add (optional - makes it easy to orient your MovieClip properly)
  8. *
  9. Tolerance (default is 0.01, but increase this if the rotation seems to jitter during the tween)
  10. *

* * The orientToBezier property should be an Array containing one Array for each set of these values. * For maximum flexibility, you can pass in any number of arrays inside the container array, one * for each rotational property. This can be convenient when working in 3D because you can rotate * on multiple axis. If you're doing a standard 2D x/y tween on a bezier, you can simply pass * in a boolean value of true and TweenLite/Max will use a typical setup, [["x", "y", "rotation", 0, 0.01]]. * Hint: Don't forget the container Array (notice the double outer brackets)

* * USAGE:

* * import com.greensock.TweenLite;
* import com.greensock.plugins.TweenPlugin;
* import com.greensock.plugins.BezierThroughPlugin;
* TweenPlugin.activate([BezierThroughPlugin]); //activation is permanent in the SWF, so this line only needs to be run once.

* * TweenLite.to(mc, 2, {bezierThrough:[{x:250, y:100}, {x:50, y:200}, {x:500, y:200}]});
