public static function easeIn(t:Number, b:Number, c:Number, d:Number):Number
Easing equation function for a quartic easing
in : accelerating from zero velocity.
Parameters
| t:Number — Current time (in frames or seconds).
|
| |
| b:Number — Starting value.
|
| |
| c:Number — Change needed in value.
|
| |
| d:Number — Expected easing duration (in frames or seconds).
|
Returns
| Number — Interpolated value.
|
public static function easeInOut(t:Number, b:Number, c:Number, d:Number):Number
Easing equation function for a quartic easing
in / out : acceleration until halfway, then deceleration.
Parameters

|
| |
| b:Number — Starting value.
|
| |
| c:Number — Change needed in value.
|
| |
| d:Number — Expected easing duration (in frames or seconds).
|
Returns
| Number — Interpolated value.
|
public static function easeOut(t:Number, b:Number, c:Number, d:Number):Number
