Public Methods
 MethodDefined by
  
easeIn(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeIn() method starts the motion by backtracking, then reversing direction and moving toward the target.

easeInOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number
[static] The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion by backtracking, then reversing direction and moving toward target, overshooting target slightly, reversing direction again, and then moving back toward the target.

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

The easeIn() method starts the motion by backtracking, then reversing direction and moving toward the target.

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.
 
s:Number (default = 0) — Specifies the amount of overshoot, where the higher the value, the greater the overshoot.

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

The easeInOut() method combines the motion of the easeIn() and easeOut() methods to start the motion by backtracking, then reversing direction and moving toward target, overshooting target slightly, reversing direction again, and then moving back toward the target.

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.
 
s:Number (default = 0) — Specifies the amount of overshoot, where the higher the value, the greater the overshoot.

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

The easeOut() method starts the motion by moving towards the target, overshooting it slightly, and then reversing direction back toward the target.

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.
 
s:Number (default = 0) — Specifies the amount of overshoot, where the higher the value, the greater the overshoot.

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