5.
Addtheobjectsanddelegatesintotheir
respective columns.
6. Click Alig n Objects With Delegates, and then
click Link Objects To Delegates, and then click
OK to exit the dialog.
The objects align themselves with the delegates
and are linked to the delegates.
Next, animate the delegates with behav iors.
See Assigning B ehaviors (page 2–1159) for
information on using behaviors.
When you solve the simulation, the cloned
objects follow the delegates, which are guided
by behaviors. You then generate motion
sy nthesis based on the delegate movement.
7. Select the Crowd object. On the Modify panel
> Global Clip Controllers rollout, click New,
and use the Select dialog to select the Global
object from step 1.
TheobjectappearsintheGlobalClip
Controllers rollout list.
8. In the list, click the object, and then click the
Edit button.
The Synthesis dialog displays. Its name is that
of the object.
9. On the Motion Clips panel, tur n off all check
boxes in the From Glob al Object and Remove
Local groups.
Use these options only if your original object
has lateral motion to coordinate with footsteps.
10. On the Motion Clips panel, click New.
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 fr ame range
for the motion clip.

12. Continue to define clips using different frame
ranges from the Global object’s animation.
Give the clips descriptive names.
Next, you define states whose parameters
determine when motion synthesis is to use each
clip.
13. Click the State tab, and then click New State.
A new state is added to the drop-down list at
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 specify 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 active
only if acceleration is less than 0.
14. Click Edit Properties and define how the
software should ac t ivate the clip, based on any
combination of speed, acceleration, and so on.

check b ox, and set parameters. Click Exit to
exit the dialog.
When using a range, make sure the Min setting
is lower than t he Max sett ing. 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 st ate.
For example, if you ’ve defined a state whose
acceleration is less than 0, you might associat e
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.
