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
