Runtime Versions: Flash Player 9.0, AIR 1.0

The None class defines easing functions to implement nonaccelerated motion with ActionScript animations. Its methods all produce the same effect, a constant motion. The various names, easeIn, easeOut and so on are provided in the interest of polymorphism. The None class is identical to the fl.motion.easing.Linear class in functionality.

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

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0, AIR 1.0

The easeIn() method defines a constant motion, with no acceleration.

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.
