Skews a movieclip like in the Flash IDE's transform panel.
You can specify the duration, easing equation and callback properties either with setting the properies directly or with the animationStyle() method like it is used in de.alex_uhlmann.animationpackage.drawing.
Example 1:
Example 2: The alternative way is shorter. The same like above in one line.var mySkew:Skew = new Skew(mc.inner_mc); mySkew.animationStyle(1000,Sine.easeInOut,"onCallback"); mySkew.skewHorizontal(30);
Example 3: You can also specify the properties via the constructor. This might come in handy if you're using the Sequence or Parallel class. Take a look at their class documentations for more information. The animate() method and its start and end percentage parameters might also be useful.new Skew(mc.inner_mc).skewHorizontal(30,1000,Sine.easeInOut,"onCallback");
Example 4: By default, the start value of your animation is the current value. You can explicitly define the start values either via the setStartValue or run method or via the constructor. Here is one example for the constructor solution. This also might come in handy using composite classes, like Sequence.var mySkew:Skew = new Skew(mc.inner_mc,"HORIZ",30,1000,Sine.easeInOut,"onCallback"); mySkew.animate(0,100);
var mySkew:Skew = new Skew(mc.inner_mc,"HORIZ",[-30,30],2000,Sine.easeInOut); mySkew.skewHorizontal();
usage:
var mySkew:Skew = new Skew(inner_mc);
var mySkew:Skew = new Skew(inner_mc, type, degree);
var mySkew:Skew = new Skew(inner_mc, type, degree, duration);
var mySkew:Skew = new Skew(inner_mc, type, degree, duration, callback);
var mySkew:Skew = new Skew(inner_mc, type, degree, duration, easing, callback);
var mySkew:Skew = new Skew(inner_mc,type, values);
var mySkew:Skew = new Skew(inner_mc,type, values, duration, callback);
var mySkew:Skew = new Skew(inner_mc,type, values, duration, easing, callback);
parameters:
(String)(static) Property that can be used to set the skew mode.
(String)(static) Property that can be used to set the skew mode.
(MovieClip) Movieclip to animate. Movieclip must have a parent clip.
(Number) Duration of animation in milliseconds or frames. Default is milliseconds.
(Object) Easing equation in Robert Penner style. Default equation is Linear.easeNone. www.robertpenner.com/easing/
(String) Function to invoke after animation. See APCore class.
description: Skews a movieclip horizontally from its current slope to a specified slope in a specified time and easing equation. Note: only movieclips that are contained by another movieclip can be skewed.
Example 1: skew a movieclip 360 degrees horizontally in 1 second using linear easing.
new Skew(mc.inner_mc).skewHorizontal(360,1000);
Example 2: (Example .swf) skews a movieclip 30 degrees horizontally first clockwise, then counterclockwise, and then back to normal. Each animation takes 1 second using Sine easing.
var mySkew:Skew = new Skew(mc.inner_mc);
mySkew.skewHorizontal(30,1000,Sine.easeInOut,"onCallback");
myListener.onCallback = function() {
mySkew.skewHorizontal(-30,1000,Sine.easeInOut,"onCallback2");
}
myListener.onCallback2 = function() {
mySkew.skewHorizontal(0,1000,Sine.easeInOut);

description: Skews a movieclip vertically from its the current slope to a specified slope in a specified time and easing equation. Note: only movieclips that are contained by another movieclip can be skewed.
Example 1: skew a movieclip 360 degrees vertically in 1 second using linear easing.
new Skew(mc.inner_mc).skewVertical(360,1000);
Example 2: (Example .swf) skews a movieclip 30 degrees vertically first clockwise, then counterclockwise, and then back to normal. Each animation takes 1 second using Sine easing.

description: similar to the skewHorizontal() and skewVertical() methods. Offers start and end parameters.
usage:
mySkew.animate(start, end);
parameters:
returns: void
description: jumps to a specific step of the animation and stays there.
usage:
instance.goto(percentage);
parameters:
returns: void
description: set the animation style properties for your animation. Notice that if your easing equation supports additional parameters you can send those parameters with the easing parameter in animationStyle. You have to send an Array as easing parameter. The first element has to be the easing equation in Robert Penner style. The following parameters can be your additional parameters. i.e.:
See also "Customizable easing equations" in readme for more information.var myRotation:Rotation = new Rotation(mc); myRotation.animationStyle(2000,[Back.easeOut,4]); myRotation.run(360);
usage:
myInstance.animationStyle(duration);
myInstance.animationStyle(duration, callback);
myInstance.animationStyle(duration, easing, callback);
parameters:
returns: Void.
description: rounds animation results to integers. (might be usefull for animating pixelfonts). Default is false.
usage:
myInstance.roundResult(rounded);
parameters:
true rounds the result. Animates with integers. Less accuracy. false animates with floating point numbers.returns: Void.
description: Flash does not guaranteed that time-based tweening will reach the end value(s) of your animation. By default AnimationPackage guarantees that the end value(s) will be reached. The forceEnd method allows you to disable this guarantee and only accept the values from your easing equation. In certain situations this can lead to a smoother ending of the animation. Notice that in frame-based tweening the end value(s) will always be reached.
usage:
myInstance.forceEnd(forceEndVal);
parameters:
true or false.returns: Void.
description: returns the optimization mode. See setOptimizationMode for more information.
usage: getOptimizationMode();
returns: Boolean
description:
Allows to explicitly remove parts of the animation that don't change during
the animation.
This can add additional performance to your animation. Note that
setting this method to true has side effects. If all start and end values match,
the animation won't start and will immediatly invoke an onEnd event.
The order of values returned by getStartValue(s), getCurrentValue(s),
getEndValue(s) and the value property of the eventObject returned
by EventDispatcher might change if you set this method to true. You can
still retrieve the parts of the animation that are actually animated
if you access the Animator instance of your animation class via
myAnimator. Ask myInstance.myAnimator.setter to retrieve
all currently animated parts of the animation. See Animator
documentation. Of cource, if you know your input values you would
probably look at them.
Note that the AnimationCore class offers a static setOptimizationModes method (note the last "s" at the end) that allows you to remove parts of 'all' your animations that don't change during the animation.

myInstance.setOptimizationMode(optimize);
