Method Detail

easeIn

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

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

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

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

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

easeOut

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

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

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