Class | public class Back
Inheritance | Back Object

The Back class defines three easing functions to implement motion with Flex effect classes. For more information, see http://www.robertpenner.com/profmx.

Public Methods

| Method | Defined 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. | Back
|  | 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. | Back
|  | easeOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0):Number [static] The easeOut() method starts the motion by moving towards the target, overshooting it slightly, and then reversing direction back toward the target. | Back

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 : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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`

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 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`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.
