Methods

_runFrame

private static void _runFrame ( )
Called per Interval to handle each animation frame.

getBezier

Configuration Attributes

direction - String

How iterations of the animation should behave. Possible values are "normal" and "alternate". Normal will repeat the animation, alternate will reverse on every other pass.
Default Value: "normal"

duration - NUM

The length of the animation. Defaults to "1" (second).

easing - Function

The method that will provide values to the attribute(s) during the animation. Defaults to "Easing.easeNone".

elapsedTime - Int

Current time the animation has been running.
Default Value: 0

from - Object supports any unit, provided it matches the "to" (or default) unit (e.g. "{width: 10em', color: 'rgb(0, 0 0)', borderColor: '#ccc'}". If using the default ('px' for length-based units), the unit may be omitted ( (e.g. "{width: 100}, borderColor: 'ccc'}", which defaults to pixels and hex, respectively).

The starting values for the animated properties. Fields may be strings, numbers, or functions. If a function is used, the return value becomes the from value. If no from value is specified, the DEFAULT_GETTER will be used.

iterationCount - Int

The number of iterations that have occurred. Resets when an animation ends (reaches iteration count or stop() called).
Default Value: 0

iterations - Int

The number of times the animation should run
Default Value: 1

node - Node

The object to be animated.

paused - Boolean

Whether or not the animation is currently paused.
Default Value: false

reverse - Boolean

If true, animation begins from last frame
Default Value: false

running - Boolean

Whether or not the animation is currently running.
Default Value: false

startTime - Int

Date stamp for the first frame of the animation.
Default Value: 0

to - Object supports any unit, provided it matches the "from" (or default) unit (e.g. "{width: '50%', color: 'red', borderColor: '#ccc'}". If using the default ('px' for length-based units), the unit may be omitted ( (e.g. "{width: 100}, borderColor: 'ccc'}", which defaults to pixels and hex, respectively).

The ending values for the animated properties. Fields may be strings, numbers, or functions.
