Property Detail
alignToPathproperty
public var alignToPath:Boolean

Defines whether the 3d object aligns its rotation to the axis of the path while animating along the path. Defaults to false.

offsetproperty 
public var offset:Vector3D

sets an optional offset to the position on the path, ideal for cameras or reusing the same Path object for parallel animations

pathproperty 
path:Path

defines the path used by the animation.


Implementation
    public function get path():Path
    public function set path(value:Path):void

positionproperty 
position:Vector3D  [read-only]

returns the current interpolated position on the path with no optional offset applied


Implementation
    public function get position():Vector3D
rotationproperty 
rotation:Vector3D  [read-only]

returns the current interpolated rotation along the path.


Implementation
    public function get rotation():Vector3D
rotationsproperty

Constructor Detail
PathAnimator()Constructor
public function PathAnimator(path:Path = null, target:Object3D = null, init:Object = null)

Creates a new PathAnimator

Parameters
path:Path (default = null) — [optional] Defines the Path object used tp define the path of the animation.
 
target:Object3D (default = null) — [optional] Defines the 3d object to which the animation is applied.
 
init:Object (default = null) — [optional] An initialisation object for specifying default instance properties.

Method Detail
getDefaultFps()method
override protected function getDefaultFps():Number

Returns
Number
getPathPosition()method 
public function getPathPosition(time:Number, position:Vector3D = null):Vector3D

Returns a position on the path determined by the elapsed time given.

Parameters

time:Number — A number representing the elapsed time in seconds.
 
position:Vector3D (default = null) — [optional] A 3d number object representing the instance to be returned.

Returns
Vector3D — A Vector3D object representing the position.
getPositionOnPath()method 
public function getPositionOnPath(p:Vector3D, t:Number):void

Updates a position Vector3D on the path at a given time. Do not use this handler to animate, it's in there to add dummy's or place camera before or after the animated object. Use the update() method or progress property instead.

Parameters

p:Vector3D — Vector3D. The Vector3D to update according to the "t" time parameter.
 
t:Number — Number. A Number from 0 to 1

update
getTimeSegment()method 
public function getTimeSegment(t:Number):Number

returns the segment index that is used at a given time;

Parameters

t:Number (default = NaN) — [Number]. A Number between 0 and 1. If no params, actual pathanimator time segment index is returned.

Returns
Number
updateProgress()method 
override protected function updateProgress(val:Number):void

Parameters

val:Number

updateTarget()method 
override protected function updateTarget():void
