Important:
Several Simulation behavior parameters contain object wells into which target
objects used as attractors, repellers, orbiters, and so on, are dragged. Dragging an object
to a well may be tricky—be sure to click the object name in the Layers tab and immediately
drag the object to the object well (without releasing the mouse button). The behavior
must remain active even though you are dragging another object in the Layers tab. If
you click the object in the Layers tab and release the mouse button, that object becomes
selected, and the behavior’s parameters are no longer displayed. This behavior is true of
all wells, including mask source and image wells.

Align To Motion
The Align To Motion behavior changes the rotation of an object to match changes made
to its direction along an animation path. This behavior is meant to be combined with
Simulation behaviors that animate the position of an object or with a keyframed animation
path you create yourself.
