USING FLASH CS4 PROFESSIONAL
Timelines and Animation
Delete a motion preset
You can remove presets from the Motion Presets panel. When you remove a preset, Flash deletes its XML file from
disk. Consider making a backup of any presets you might want to use again later by exporting copies of them first.
1
Select the preset to delete in the Motion Presets panel.
2
Do one of the following:
Choose Remove from the panel menu.
Click the Remove item button in the panel.
Create a preview for a custom preset
You can create a preview for any custom motion presets that you create. Do this by storing a SWF file that
demonstrates the tweened animation in the same directory with the motion preset XML file.
1
Create the tweened animation and save it as a custom preset.
2
Create a FLA file that contains only a demonstration of the tween. Save the FLA with the exact same name as the
custom preset.
3
Create a SWF file from the FLA file with the Publish command.
4
Place the SWF file in the same directory as the saved custom motion preset XML file. These files are stored in the
following directories:
Windows: <hard disk>\Documents and Settings\<user>\Local Settings\Application Data\Adobe\Flash
CS4\<language>\Configuration\Motion Presets\
Macintosh: <hard disk>/Users/<user>/Library/Application Support/Adobe/Flash
CS4/<language>/Configuration/Motion Presets/
The preview now displays when the custom tween is selected in the Motion Presets panel.
Create motion tweens
Tweens are applied to symbol instances and text fields. Only symbol instances and text fields can be tweened. All other
object types are wrapped in a symbol when a tween is applied to them. The symbol instance can contain nested
symbols, which can themselves be tweened on their own timelines.
The minimal building block in a tween layer is a tween span. A tween span in a tween layer can contain only one
symbol instance. The symbol instance is called the target instance of the tween span. Adding a second symbol to the
tween span replaces the original symbol in the tween. You can change the target object of a tween by dragging a
different symbol from the library onto the tween span in the Timeline. You can delete the symbol from a tween layer
without removing or breaking the tween. You can then add a different symbol instance to the tween at a later time.
You can also change the type of the target symbol of a tween span.
You can edit individual property keyframes on Stage, in the Property inspector, or in the Motion Editor.
When you add a tween to an object or set of objects on a layer, Flash either converts the layer to a tween layer or creates
a new layers to preserve the original stacking order of the objects on the layer, according to these rules:
If there are no objects on the layer other than the selection, the layer changes to a tween layer.
If the selection is at the bottom of the stacking order of the layer (under all other objects), a layer will be created
above the original layer to hold the non-selected items and the original layer becomes a tween layer.
If the selection is at the top of the stacking order of the layer (above all other objects), a new layer is created, the
selection is moved to it and that layer becomes a tween layer.
