Packagefl.motion.easing
Classpublic class Exponential

The Exponential class defines three easing functions to implement motion with ActionScript animation. It produces an effect similar to the popular "Zeno's paradox" style of scripted easing, where each interval of time decreases the remaining distance by a constant proportion.

easeIn(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeIn() method starts motion slowly and then accelerates motion as it executes.
Exponential
  
easeInOut(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion from a zero velocity, accelerate motion, then decelerate to a zero velocity.
Exponential
  
easeOut(t:Number, b:Number, c:Number, d:Number):Number
[static] The easeOut() method starts motion fast and then decelerates motion to a zero velocity as it executes.

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

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

Parameters
t:Number — Specifies the current time, between 0 and duration inclusive.
 
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.

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

easeInOut()method 
public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number

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

Parameters
t:Number — Specifies the current time, between 0 and duration inclusive.
 
b:Number — Specifies the initial value of the animation property.
 
c:Number — Specifies the total change in the animation property.
 
d:Number — Specifies the duration of the motion.

Returns
Number — The value of the interpolated property at the specified time.

easeOut()method 
public static function easeOut(t:Number, b:Number, c:Number, d:Number):Number

The easeOut() method starts motion fast and then decelerates motion to a zero velocity as it executes.

Parameters
t:Number — Specifies the current time, between 0 and duration inclusive.
 
b:Number — Specifies the initial value of the animation property.
 
c:Number — Specifies the total change in the animation property.
 
d:Number — Specifies the duration of the motion.

Returns
Number — The value of the interpolated property at the specified time.
