The Back class defines three easing functions to implement
motion with Flex effect classes.

public static function easeIn(t:Number, b:Number, c:Number, d:Number, s:Number = 0, ... rest):Number
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) |
| |
| ... rest |
Returns
| Number — Number corresponding to the position of the component.
|
public static function easeInOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0, ... rest):Number
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) |
| |
| ... rest |
Returns
| Number — Number corresponding to the position of the component.
|
public static function easeOut(t:Number, b:Number, c:Number, d:Number, s:Number = 0, ... rest):Number
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) |
| |
| ... rest |
Returns
| Number — Number corresponding to the position of the component.
