In the following example, a graphic of an airplane is shown travelling a spiral motion
path. On its own, the orientation of the graphic doesn’t change, because only the Position
parameter is affected.
If you add the Snap Alignment to Motion behavior to the airplane graphic, the Rotation
parameter is affected so the graphic points in the direction of motion, without the need
for additional keyframing.
Parameters in the Inspector
Rotation Axis: A pop-up menu that lets you rotate the object around the X, Y, or Z axis.
You can also choose All to rotate the object around all three axes. The default rotation
axis is Z. All uses the acceleration direction as “up,” like a roller coaster.
Axis: A pop-up menu that lets you specify whether the object aligns to its horizontal or
vertical axis.
Invert Axis: If the object is aligning on the correct axis, but appears backwards, this
checkbox flips the object so it faces the proper direction.
