constraining the translation of joints
You don’t normally think of joints that can move positions. However, in Flash
Professional CS6, you can allow joints to actually slide in either the x (horizontal)
or the y (vertical) direction, and set the limits on how far those joints can travel.
In this example, you’ll allow the first node (the tall first segment of the crane) to
move back and forth as if it were on a track. This will give it the capability to pick
up any sort of cargo from the ocean and place it on the dock.
1 Click on the first node in the crane armature.
2 Deselect the Enable option in the Joint: Rotation section of the Properties
inspector.
