471 EXTENDING FLASH CS4 PROFESSIONAL
Timeline object
Usage
timeline.createMotionTween([startFrameIndex [, endFrameIndex]])
Parameters
startFrameIndex A zero-based index that specifies the beginning frame at which to create a motion tween. If you
omit startFrameIndex, the method uses the current selection. This parameter is optional.
endFrameIndex A zero-based index that specifies the frame at which to stop the motion tween. The range of frames
goes up to, but does not include, endFrameIndex. If you specify only startFrameIndex, endFrameIndex defaults to the
startFrameIndex value. This parameter is optional.
Returns
Nothing.
Description
Method; sets the
frame.tweenType property to motion for each selected keyframe on the current layer, and converts
each frame’s contents to a single symbol instance if necessary. This property is the equivalent to the Create Motion
Tween menu item in the Flash authoring tool.
Example
The following example converts the shape in the first frame up to, but not including, Frame 10 to a graphic symbol
instance and sets the
frame.tweenType to motion (remember that index values are different from frame number
values):
fl.getDocumentDOM().getTimeline().createMotionTween(0, 9);
timeline.currentFrame
Availability
Flash MX 2004.
Usage
timeline.currentFrame
Description
Property; the zero-based index for the frame at the current playhead location.
Example
The following example sets the playhead of the current timeline to Frame 10 (remember that index values are different
from frame number values):
fl.getDocumentDOM().getTimeline().currentFrame = 9;
The following example stores the value of the current playhead location in the curFrame variable:
var curFrame = fl.getDocumentDOM().getTimeline().currentFrame;
