Classpublic class Elastic
InheritanceElastic Inheritance Object

The Elastc class defines three easing functions to implement motion with Flex effect classes, where the motion is defined by an exponentially decaying sine wave. For more information, see http://www.robertpenner.com/profmx.

Public Methods
 MethodDefined by
  
easeIn(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number
[static] The easeIn() method starts motion slowly, and then accelerates motion as it executes.
Elastic
  
easeInOut(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion slowly, accelerate motion, then decelerate.
Elastic
  
easeOut(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number
[static] The easeOut() method starts motion fast, and then decelerates motion as it executes.

Method detail
easeIn()method
public static function easeIn(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number

The easeIn() method starts motion slowly, and then accelerates motion as it executes.

Parameters
t:Number — Specifies time.
 
b:Number — Specifies the initial position of a component.
 
c:Number — Specifies the total change in position of the component.
 
d:Number — Specifies the duration of the effect, in milliseconds.
 
a:Number (default = 0) — Specifies the amplitude of the sine wave.
 
p:Number (default = 0) — Specifies the period of the sine wave.

Returns
Number — Number corresponding to the position of the component.
easeInOut()method 
public static function easeInOut(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number

The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion slowly, accelerate motion, then decelerate.

Parameters
t:Number — Specifies time.
 
b:Number — Specifies the initial position of a component.
 
c:Number — Specifies the total change in position of the component.
 
d:Number — Specifies the duration of the effect, in milliseconds.
 
a:Number (default = 0) — Specifies the amplitude of the sine wave.
 
p:Number (default = 0) — Specifies the period of the sine wave.

Returns
Number — Number corresponding to the position of the component.
easeOut()method 
public static function easeOut(t:Number, b:Number, c:Number, d:Number, a:Number = 0, p:Number = 0):Number

The easeOut() method starts motion fast, and then decelerates motion as it executes.

Parameters
t:Number — Specifies time.
 
b:Number — Specifies the initial position of a component.
 
c:Number — Specifies the total change in position of the component.
 
d:Number — Specifies the duration of the effect, in milliseconds.
 
a:Number (default = 0) — Specifies the amplitude of the sine wave.
 
p:Number (default = 0) — Specifies the period of the sine wave.

Returns
Number — Number corresponding to the position of the component.
