Add the Dolly Camera behavior

Another way to manipulate the view of a 3D world during movie playback is to dolly the camera. Dollying is a motion picture technique in which the camera's position changes without changing the direction of the lens itself (as if the camera were transported forward and backward, without turning, on a tripod with wheels).

For dollying, you will drag the behavior to the Score rather than the Stage.

1 | If the Score is not open, select Window > Score.
2 | In the Library palette, verify that 3D > Actions is selected.
3 | Drag the Dolly Camera action from the Library palette to the Magic tricks sprite in the Score. Release the mouse button when the pointer appears with a plus sign and empty rectangle.
4 | In the Parameters for Dolly Camera dialog box, specify the following:
| In the "Amount to dolly per frame" text box, type 20.
| The Dolly Camera action moves in world units, which are units of measurement unique to the 3D world.
| In the "Which group does this behavior belong to?" text box, type Dolly. Then click OK.
