easeInFraction
property, it
then uses uniform (linear) motion through the next phase, and
finally decelerates until the end during the period specified
by the easeOutFraction
property.
The easing values for the three phases are calculated such that the behavior of constant acceleration, linear motion, and constant deceleration all occur within the specified duration of the animation.
Strict linear motion can be achieved by setting
easeInFraction
and easeOutFraction
to 0.0.
Note that if acceleration or
deceleration are not 0.0, then the motion during the middle
phase is not at the same speed as that of pure
linear motion. The middle phase consists of
uniform motion, but the speed of that motion is determined by
the size of that phase relative to the overall animation.
The <s:Linear>
tag
inherits all of the tag attributes of its of its superclass,
and adds the following tag attributes:

public function ease(fraction:Number):Number
Wersja języka: | ActionScript 3.0 |
Wersja produktu: | Flex 4 |
Wersje środowiska wykonawczego: | Flash Player 10, AIR 1.5 |
Calculates the eased fraction value based on the
easeInFraction
and easeOutFraction
properties.
If fraction
is less than easeInFraction
, it calculates a value
based on accelerating up to the linear motion phase.
If fraction
is greater than easeInFraction
and less than
(1-easeOutFraction)
, it calculates a value based
on the linear motion phase between the easing in and easing out phases.
Otherwise, it calculates a value based on constant deceleration
between the linear motion phase and 0.0.
Parametry
fraction:Number — The elapsed fraction of the animation,
between 0.0 and 1.0..
|
Number — The eased fraction of the animation.
