rotation, or scale of an object in an animation. We will use the
translation of a sphere to control the translation of a cube.
Set up a scene as shown in Figure 14.14. The object to
which the constraint is applied is called the owner. This is the
object that will be controlled; in this case, it's the cube. The
controlling object (the sphere) is the target. Set up an anima-
tion of the cube to translate along the x -axis from -3 grid units
at frame 1.00 to +3 grid units at frame 100.00 (see Chapter 9
for a refresher on animation basics).
With the animation of the cube created, select the cube in
the 3D window and add an action constraint by going to the
properties window - “Object Constraints” button, clicking on
“Add Constraint,” and selecting “Action” from the drop down
menu. Set the values in the action constraint panel as shown
in Figure 14.15.
Target. The controlling object (sphere).
Action. The animation of the cube (“CubeAction”).
Translation. “Location X,” movement along the x -axis.
