Movie Symbols
Rotation
Now let’s create another part of the train – wheel. If it’s moving – it may be done as a movie symbol.-
Create a drawing of the wheel
- Select it and transform it to a graphic symbol grWheel
- Select it again and transform it to movie symbol mvWheel. Check if it’s in the right sequence – Scene1-mvWheel-grWheel
- Enter mvWheel (it must be Scene1-mvWheel on the bar)
- Expand timeline of mvWheel up to the 15 frames
- Insert keyframes in frame 5 , 10 and 15
- Highlight frame 5 and open Menu-Window-Transform panel (Ctrl-T shortcut)
- Change the Rotation to 120 degrees. Hit Enter key to confirm
- Highlight frame 10 and through Transform Panel change the Rotation to –120 degrees
- You may also change the Rotation of Frame 15 to –1 degree
- Insert Motion Tween between frames 1-5, 5-10, 10-15
Test your movie. You should see rotating wheel.
This is the simple way to simulate rotation. To make the rotation smooth – make sure that the frame intervals match the rotation degree
