6.7 MOVE & DIR

As you probably have already realized, the direction method is a very powerful way to create many kinds of nice animations. However, there are situations where you have to control the direction of the object independently from the motion; that is not possible with the direction method, because it uses the same curve to define both the direction and the motion. MOVE & DIR method is designed for these situations.

The move & dir method uses two parameters: the first one defines a motion for target objects just as the path method parameter does, and the second parameter defines the direction for the targets just as the direction method parameter does. This means that if both parameter curves are equal, the method will work exactly the same way as the direction method does and if the parameter defining the direction is a straight line, the method works similar to the path method (because the direction of the object remains constant).
