Method Detail
easeIn | () | method |
public static function easeIn(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0, AIR 1.0 |
The easeIn() method starts the motion by backtracking and
then reversing direction and moving toward the target.
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.
| |
s:Number (default = 0) |
Number — The value of the interpolated property at the specified time.
|
Example ( How to use this example )
This example animates a rectangle using the
Back.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", Back.easeIn, startValue, finishValue, duration, true); myTween.looping = true;
easeInOut | () | method |
public static function easeInOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0, AIR 1.0 |
The easeInOut() method combines the motion
of the easeIn() and easeOut() methods
to start the motion by backtracking, then reversing direction and
moving toward the target, overshooting the target slightly, reversing
direction again, and then moving back toward the target.
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.
| |
s:Number (default = 0) |
Number — The value of the interpolated property at the specified time.

Back.easeInOut 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", Back.easeInOut, startValue, finishValue, duration, true); myTween.looping = true;
easeOut | () | method |
public static function easeOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0, AIR 1.0 |
The easeOut() method starts the motion by
moving towards the target, overshooting it slightly,
and then reversing direction back toward the target.
