Describing the animation

Flash Player 9 and later, Adobe AIR 1.0 and later, requires Flash CS3 or later

The addPropertyArray() method of the MotionBase class adds an array of values to describe every tweened property.

Potentially the array contains one array item for every keyframe in the motion tween. Often some of these arrays contain fewer items than the total number of keyframes in the motion tween. This situation occurs when the last value in the array does not change for the remaining frames.

If the length of the array argument is greater than the duration property of the Motion object, addPropertyArray() adjusts the value of the duration property accordingly. It does not add keyframes for the properties that were previously added. The newly added keyframes persist for the extra frames of the animation.

The x and y properties of the Motion object describe the changing position of the tweened object as the animation is running. These coordinates are the values that are most likely to change in every keyframe, if the position of the display object changes. You can add additional motion properties with the addPropertyArray() method. For example, add the scaleX and scaleY values if the tweened object is resized. Add the s cewX and skewY values if it is skewed. Add the rotationConcat property if it rotates.

Use the addPropertyArray() method to define the following tween properties:

x

horizontal position of the transformation point of the object in the coordinate space of its parent

y

vertical position of the transformation point of the object in the coordinate space of its parent

z

depth (z-axis) position of the transformation point of the object in the coordinate space of its parent

scaleX

horizontal scale as a percentage of the object as applied from the transformation point

scaleY

vertical scale as a percentage of the object as applied from the transformation point

skewX

horizontal skew angle of the object in degrees as applied from the transformation point

skewY

vertical skew angle of the object in degrees as applied from the transformation point

rotationX

rotation of the object around the x-axis from its original orientation

rotationY

rotation of the object around the y-axis from its original orientation

rotationConcat

rotation (z-axis) values of the object in the motion relative to previous orientation as applied from the transformation point

useRotationConcat

If set, causes the target object to rotate when addPropertyArray() supplies data for motion

blendMode

BlendMode class value specifying mixture the colors of the object with graphics underneath

matrix3D

matrix3D property if one exists for the keyframe; used for 3D tweens; if used, all the previous transform properties are ignored

rotationZ

z-axis rotation of the object, in degrees, from its original orientation relative to the 3D parent container; used for 3D tweens instead of rotationConcat

The properties that are added in the automatically generated script depend on the properties that were assigned to the motion tween in Flash. You can add, remove, or modify some of these properties when customizing your own version of the script.

The following code assigns values to the properties of a motion tween named __motion_Wheel. In this case, the tweened display object does not change location but rather spins in place throughout the 29 frames in the motion tween. The multiple values assigned to the rotationConcat array define the rotation. The other property values of this motion tween do not change.

__motion_Wheel = new Motion(); 
__motion_Wheel.duration = 29; 
__motion_Wheel.addPropertyArray("x", [0]); 
__motion_Wheel.addPropertyArray("y", [0]); 
__motion_Wheel.addPropertyArray("scaleX", [1.00]); 
__motion_Wheel.addPropertyArray("scaleY", [1.00]); 
__motion_Wheel.addPropertyArray("skewX", [0]); 
__motion_Wheel.addPropertyArray("skewY", [0]); 
__motion_Wheel.addPropertyArray("rotationConcat",

__motion_Wheel.addPropertyArray("blendMode", ["normal"]); 

In the next example, the display object named Leaf_1 moves across the stage. Its x and y property arrays contain different values for each of the 100 frames of the animation. In addition, the object rotates on its z axis as it moves across the stage. The multiple items in the rotationZ property array determine the rotation.

__motion_Leaf_1 = new MotionBase(); 
__motion_Leaf_1.duration = 100; 
__motion_Symbol1_4.addPropertyArray("y",
