Language Version : ActionScript 3.0
Player Version : Flash Player 9.0

The Strong class defines three easing functions to implement motion with ActionScript animation. The acceleration of motion for a Strong easing equation is greater than for a Regular easing equation. The Strong class is identical to the fl.motion.easing.Quintic class in functionality.

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

Language Version : ActionScript 3.0
Player Version : Flash Player 9.0

The easeIn() method starts motion from zero velocity and then accelerates motion 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.

Example

This example animates a rectangle using the Strong.easeIn easing function: 
import fl.transitions.*;
import fl.transitions.easing.*;

stage.frameRate = 31;

var box:Sprite = new Sprite();
box.graphics.beginFill(Math.random() * 0xFFFFFF);
box.graphics.drawRect(0, 0, 100, 350);
box.graphics.endFill();
box.x = 50;
box.y = 10;
addChild(box);

var startValue:Number = box.x;
var finishValue:Number = 400;
var duration:Number = 3;
var myTween:Tween = new Tween(box, "x", Strong.easeIn, startValue, finishValue, duration, true);
myTween.looping = true;
easeInOut()method 
public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number

Language Version : ActionScript 3.0
Player Version : Flash Player 9.0

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

Language Version : ActionScript 3.0

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.
