addFilterPropertyArray | () | method |
public function addFilterPropertyArray(index:int, name:String, values:Array, startFrame:int = -1, endFrame:int = -1):void
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Modifies a filter property in all corresponding keyframes for a Motion object. Call initFilters()
before
using this method. The order of the values in the array determines the assignment of each value
to the filter property for all keyframes. For each non-null value in the specified values
array, this method finds the keyframe corresponding to the value's index position in the array,
and stores the property name/value pair for the filter in the keyframe.
Parameters
index:int — The zero-based index position in the array of filters.
| |
name:String — The name of the filter property to store in each keyframe.
| |
values:Array — The array of values for the property specified in the name
parameter. Each non-null value is assigned to the filter in a keyframe that corresponds to
the value's index in the array.
| |
startFrame:int (default = -1 )
| |
endFrame:int (default = -1 )

Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Stores an array of values in corresponding keyframes for a declared property of the Motion class.
The order of the values in the array determines the assignment of each value to a keyframe. For each
non-null value in the given values

corresponding to the value's index position in the array, or creates a new keyframe for that index
position, and stores the property name/value pair in the keyframe.
Parameters
name:String — The name of the Motion class property to store in each keyframe.
| |
values:Array — The array of values for the property specified in the name
parameter. Each non-null value is assigned to a keyframe that corresponds to the value's
order in the array.

getCurrentKeyframe | () | method |
public function getCurrentKeyframe(index:int, tweenableName:String = ""):KeyframeBase
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Retrieves the keyframe that is currently active at a specific frame in the Motion instance. A frame that is not a keyframe derives its values from the keyframe that preceded it.
This method can also filter values by the name of a specific tweenables property.
You can find the currently active keyframe for x
, which may not be
the same as the currently active keyframe in general.
Parameters
index:int — The index of a frame in the Motion instance, as an integer greater than or equal to zero.
| |
tweenableName:String (default = " ") — Optional name of a tweenable's property (like "x" or "rotation" ).
|
KeyframeBase — The closest matching keyframe at or before the supplied frame index.

public function getFilters(index:Number):Array
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Retrieves an interpolated array of filters at a specific time index in the Motion instance.
Parameters
index:Number — The time index of a frame in the Motion, as an integer greater than or equal to zero.
|
Array — The interpolated array of filters.
If there are no applicable filters, returns an empty array.

public function getMatrix(index:int):Matrix
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 10, AIR 1.5, AIR 1.0 |
Returns the Matrix object for the specified index position of the frame of animation.
Parameters
index:int — The zero-based index position of the frame of animation containing the matrix.
|
Matrix — The Matrix object, or null value. This method can return a null value even if
MotionBase.is3D is false , because other motion tween property changes can be used
without a Matrix object.

Returns the Matrix3D object for the specified index position of the frame of animation.
Parameters
index:int — The zero-based index position of the frame of animation containing the 3D matrix.
|
Object — The Matrix3D object, or null value. This method can return a null value even if
MotionBase.is3D is true , because other 3D motion tween property changes can be used
without a Matrix3D object.

getNextKeyframe | () | method |
public function getNextKeyframe(index:int, tweenableName:String = ""):KeyframeBase
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Retrieves the next keyframe after a specific frame in the Motion instance. If a frame is not a keyframe, and is in the middle of a tween, this method derives its values from both the preceding keyframe and the following keyframe.
This method also allows you to filter by the name of a specific tweenables property to find the next keyframe for a property, which might not be the same as the next keyframe in general.
Parameters
index:int — The index of a frame in the Motion instance, as an integer greater than or equal to zero.
| |
tweenableName:String (default = " ") — Optional name of a tweenable's property (like "x" or "rotation" ).
|
KeyframeBase — The closest matching keyframe after the supplied frame index.

initFilters | () | method |
public function initFilters(filterClasses:Array, gradientSubarrayLengths:Array, startFrame:int = -1, endFrame:int = -1):void
Language Version: | ActionScript 3.0 |
Product Version: | Flash CS3 |
Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Initializes the filters list for the target object and copies the list of filters to each Keyframe instance of the Motion object.
Parameters
filterClasses:Array — An array of filter classes. Each item in the array is the fully qualified
class name (in String form) for the filter type occupying that index.
| |
gradientSubarrayLengths:Array — An array of numbers containing a value for every filter that will be in the filters
list for the motion (every class name in the filterClasses array). A value in the
gradientSubarrayLengths array is only used if the filter class entry at the same index position in the
filterClasses array is GradientGlowFilter or GradientBevelFilter.
The corresponding value in the gradientSubarrayLengths array is a number that determines the length for the arrays
that initialize the colors , alphas , and ratios parameters for the
GradientGlowFilter and GradientBevelFilter constructor functions.
