This opens the MotionClip Parameters dialog,
which lets you set the name, color , and frame
range for a motion clip.
11. Choose a descriptive name and a frame range
for the motion clip.

your glide animation.
12. Continue to define clips us ing different frame
ranges from the Global object’s animation.
Give the clips descriptive names.
Next, you define states w hose parameters

13. Click the State tab, and then click New State.

the top of the Synthesis States group. Give the
state a descriptive name. In many cases, the

that’s to be associated with it.
Next, you specif y the state’s parameters; that is,
how the delegate should be moving when the
associated object is to use its motion clip. For
example, your glide motion should be act ive
only if acceleration is less than 0.
14. Click Edit Properties and define how the
software should ac tivate the clip, based on any
combination of speed, acceleration, and so on.
Click each appropriate t ab, turn on its Use ...
check box, and set parameters. Click E xit to
exit the dialog.
When usi ng a range, make sure the Min setting
is lower than the Max setting. For example,
when using a negative range such as -180 to
-10, enter the number with the higher absolute
value (-180) as the Min setting.
You should already have several motion clips.
Now you need to associate a clip with this state.
For example, if you’ve defined a state whose
acceleration is less than 0, you might associate
the Glide clip with it.
15. In the MotionClips group, click Add Clip, and
in the Select MotionClip dialog, highlight a clip
and click OK.
16. Repeat steps 14 and 15 for each state to be used
in motion synthesis.
17. Go to the Synthesis panel, click New Master
Motion Clip, and add all of the cloned objects.
18. Click Auto Blend All and then click Synthesize
All.
The synthesis occurs as a progress bar displays.
When the synthesis is completed, the Synthesis
dialog reappears. You can now view the
ClipState parameters’ ranges and average values
by clicking State panel > Edit properties. This
is useful in fine-tuning state propert ies.
Click OK to exit t he Sy nthesis dialog.
19. Click Play. It’s not necessary to re-solve t he
simulation.
The objects follow the delegates and are
animated using clips that are activated
according to delegate motion and the states you
created.
