The Dolly behavior moves the camera a specified distance along the camera’s Z axis.
After you apply this behavior, the Dolly section of the Behaviors Inspector contains the following parameter controls:
Distance: A slider to set the distance of the dolly movement.
Speed: A pop-up menu to set the type of interpolation used for the movement. The value can be set to Constant, Ease In, Ease Out, Ease Both, Accelerate, or Decelerate.
The HUD contains the same controls as the Inspector.
