Timeline object

Parameters

frameNumIndex A zero-based index that specifies the frame index at which to insert the keyframe in the current layer.

If you omit frameNumIndex, the method uses the frame number of the current playhead or selected frame. This

parameter is optional.

Returns

Nothing.

Description

Method; inserts a keyframe at the specified frame. If you omit the parameter, the method inserts a keyframe using the

playhead or selection location.

This method works the same as timeline.insertBlankKeyframe() except that the inserted keyframe contains the

contents of the frame it converted (that is, it’s not blank).

Example

The following example inserts a keyframe at the playhead or selected location:

fl.getDocumentDOM().getTimeline().insertKeyframe();

The following example inserts a keyframe at Frame 10 of the second layer (remember that index values are different

from frame or layer number values):

fl.getDocumentDOM().getTimeline().currentLayer = 1;

fl.getDocumentDOM().getTimeline().insertKeyframe(9);

timeline.layerCount

Availability

Flash MX 2004.

Usage

timeline.layerCount

Description

Read-only property; an integer that represents the number of layers in the specified timeline.

Example

The following example uses the NumLayer variable to store the number of layers in the current scene:

var NumLayer = fl.getDocumentDOM().getTimeline().layerCount;

timeline.layers

Availability

Flash MX 2004.
