Distance the object from the path
By default, the object is locked to the motion path by its anchor point.
m
Select the Anchor Point tool from the toolbar, then drag the anchor point in the Canvas.
For more information on using the Anchor Point tool, see
on page 217.
Note: A separate Offset parameter lets you offset the starting location of the object on the
motion path (but does not offset the object from the path).
Use geometry for a motion path shape
You can use a shape that is animated with behaviors or keyframes as the source for a motion
path. This includes animated transforms (a shape changing its location in the Canvas) and
animated control points (a shape changing its shape due to keyframed control points).
1
Import (or draw) the shape to use as the path source.
2
Choose Geometry from the Path Shape pop-up menu.
The Shape Source well appears in the Inspector and HUD.
3
From the Layers list, drag the shape to the Shape Source well.
4
When the pointer becomes a curved arrow, release the mouse button.
A thumbnail of the shape appears in the well and the shape is used as the source shape for the
motion path.
Note: You can disable the source shape in the Layers list (by deselecting its activation checkbox)
so that the source shape is not visible in your project.
Select another geometry source for a motion path shape
m
Choose the object to use as the motion path’s shape source from the To pop-up menu (located
next to the Shape Source object well).
Note: To align the rotation of the object to the shape of its motion path, you can apply the Snap
Alignment to Motion behavior (in the Basic Motion behaviors subcategory).
Use the Custom Speed parameter
1
In the Inspector or HUD, choose Custom from the Speed pop-up menu.
The Custom Speed parameter becomes available. By default, a keyframe is set at the first and last
points of the behavior to create an animation of 0 percent to 100 percent, where at 0 the object
is at the beginning of the path, and at 100 the object is at the end of the path. This is the same
velocity used with the Constant preset.
2
Enable Record (press A).
Note: When Record is enabled, all keyframeable parameter value sliders are tinted red, to remind
you that any value change entered creates a keyframe.
