If adequate for your needs, use the Low quality setting rather than High. Using Low turns off anti-aliasing, which
in turn, speeds up Flash animation rendering. A handy technique is to switch the quality of the sprite to Low while
displaying a fast-moving animation sequence (such as a spinning logo), and then switch the quality back to High on
the fly as the animation slows down or comes to a stop. This way, performance can be improved during the part of
the sequence where it would be more difficult to perceive the improved quality, without sacrificing quality in the end
result.
•
Experiment with different system color depths to see what provides the best performance. For example, some
graphics, such as gradients, display faster at 16 bits.
•
Use Copy ink if possible. Transparency, using Background Transparent ink, requires much more processing
time. If your Flash sprite is in the background (no other Director sprites are behind it), use Copy instead of
Background Transparent, and author your Flash content in such a way that its background color is the same as the
background color you chose for your Director Stage.
•
Use Direct To Stage if possible. Layering and transparency are not supported in this mode; however, if you just
want to play Flash content within a box with the best performance possible, this may be the best choice.
•
Make sure that the Director movie tempo is set high enough. Unless you're using Direct To Stage, your Flash
content does not play faster than the Director movie frame rate, regardless of the
For smoothest playback, set the Director frame rate to at least 30 frames per second (fps).
•
Use Lock-Step or Fixed playback mode to adjust the Flash content frame rate. Lock-Step gives the best perfor-
mance, because playback of the Flash content is synchronized to the Director movie frame for frame.
•
Set the
property of the sprite to
static
and doesn't overlap other moving Director sprites. This keeps Director from redrawing the sprite every frame unless
it moves or changes size.
•
When modifying Flash properties by using script, set the properties for the sprite rather than for the cast
member. Setting the properties for the cast member modifies values at the cast member level and broadcasts the
change to all sprites on the Stage. This overhead can affect performance. If you have only a single sprite for the cast
member, modify the sprite property directly.
•
Limit the amount of script that executes while the Flash content plays. Avoid tight repeat loops between frames.
The usual Director performance optimizations apply when using Flash movies.
•
If you import compressed SWF files, be aware that Director will use memory for both the compressed and
decompressed versions of the file until the file has been completely decompressed into memory.
Using Director movies within Director movies
You can import a Director movie into another movie as an internal or a linked cast member, using the Import
command. As with other media types, you can link to an external movie file or import the file so that it becomes
internal media. The way you choose to import a movie affects its properties:
•
For linked movies, cast member scripts and behaviors (sprite scripts) work as before. (Select Enable Scripts in
the Linked Movie tab of the Property inspector.) Frame and movie scripts do not work. As with other types of linked
media, the external movie file must be present on the system when the host movie plays.
•
For movies imported as internal media, the movie appears as a film loop, and interactivity does not work. Use
this mainly for animations.
For both types of imported movies, the host movie controls the tempo settings, palette settings, and transitions.
Settings for these methods in the imported movie are ignored.
