By inserting keyframes at 5 frame intervals and moving and rotating
the fish, create an animation that makes the fish swim across the
stage. Use the Free Transform tool to rotate the fish (or Modify menu
> Transform > Scale and Rotate).
By altering the distance the fish moves each time (sometimes a short
distance, sometimes long), a darting effect can be achieved.
Add motion tween to make the swimming action smooth and play the movie clip,
adjusting the keyframes if necessary.
Using the ‘onion skin’ tool shows the path of my fish:
Click on Scene 1 to leave the movie clip timeline and return to the main timeline.
3. Creating the shoal of ‘swim’ movie clips
First make a blue background for your fish. Go to Modify menu > Document and
change the background colour.
Name Layer 1 ‘swim’, because it is going to contain all your ‘swim’ movie clips.
Drag the ‘swim’ movie clip from the Library onto the
stage and test the movie by pressing Ctrl+Enter.
Now you can add an ‘instance’ of the movie clip
which can be altered without changing the original.
Drag another ‘swim’ movie clip onto the stage. It
may arrive with its registration point (around which it
rotates) far away, so the first job is to move that
point.
