Timelines and Animation
Move, duplicate, or delete tween spans
•
To move a span to a new location in the same layer, drag the span.
Note:
Locking a layer prevents editing on the Stage but not the Timeline. Moving a span on top of another span
consumes the overlapped frames of the second span.
•
To move a tween span to a different layer, drag the span to the layer or copy and paste the span into the new layer.
You can drag a tween span onto an existing normal layer, tween layer, guide layer, mask layer, or masked layer. If
the new layer is a normal empty layer, it becomes a tween layer.
•
To duplicate a span, Alt-drag (Windows) or Command-drag (Macintosh) the span to a new location in the
Timeline, or copy and paste the span.
•
To delete a span, select the span and choose Remove Frames or Clear Frames from the span context menu.
Edit adjacent tween spans
•
To move the breakline between two contiguous tween spans, drag the breakline.
Each tween is recalculated.
•
To separate the adjacent start and end frames of two contiguous tween spans, Alt-drag (Windows) or Command-
drag (Macintosh) the start frame of the second span.
This allows you to make room for frames between the two spans.
•
To split a tween span into two separate spans, Ctrl-click (Windows) or Command-click (Macintosh) a single frame
in the span and then choose Split Motion from the span context menu.
Both tween spans have same target instance.
Note:
You cannot split motion if more than one frame is selected. If the tween that was split had easing applied, the
two smaller tweens may not have exactly the same motion as the original.
•
To join two contiguous tween spans, select both spans and choose Join Motions from the span context menu.
Edit the length of a tween span
•
To change the length of an animation, drag the right or left edge of the tween span.
Dragging the edge of one span into the frames of another span replaces the frames of the second span.
•
To extend the presence of a tweened object on Stage beyond either end of its tween, Shift-drag either end frame of
its tween span. Flash adds frames to the end of the span without tweening those frames.
You can also select a frame after the tween span in the same layer and press F6. Flash extends the tween span and
adds a property keyframe for all properties to the selected frame. If you press F5, Flash adds frames but will not add
a property keyframe to the selected frame.
Note:
To add static frames to the end of a span that is immediately adjacent to another span, first move the adjacent
span to make room for the new frames.
Add or remove frames within a tween span
•
To remove frames from within a span, Ctrl-drag (Windows) or Command-drag (Macintosh) to select frames and
choose Remove Frames from the span context menu.
•
To cut frames from within a span, Ctrl-drag (Windows) or Command-drag (Macintosh) to select the frames and
then choose Cut Frames from the span context menu.
