Linking Objects to Delegates
You c an link objects or bipeds to delegates to make
them follow the simulated animation.
You can link objects to delegates with 3ds Max
linking. Alternatively, the crowd system has a tool
for automatically aligning and linking objects with
delegates.
When you want to use bipeds with delegate s, you
associate bipeds with delegates rather than link
them.Thisapproachenablesthebipedstousea
motion flow network to determine their motion
during the simulation. For an explanation of how
to set up a biped crowd simulation, see Biped
Crowds (page 2–1172).
Pr ocedur es
To link objects to delegates:
1.
Set up a crowd simulation with a crowd helper
and delegates. See Creating Crowd Helpers
(page 2–1157).
2. Create a series of objects to follow the delegates.

local Y axis to point in its corresponding
delegate’s forward direction. For this reason,

local Y axes point in the direction you consider
tobe“forward”.Theeasiestwaytodothisisto
set up one object with its Y axis pointing in the
forward direction, then clone the object.
3. Select the crowd helper, a nd access the Modify
panel.
4. On the Setup rollout (page 2–1188),click
Object/Delegate Associations.
The Object/Delegate Associations dialog (page
2–1196) appears.
5. Click Add un der the Objects lis t to add objects
to link with delegates.
6. Click Add under the Delegates list to add
delegates to link with the objects you added in
the prev ious step.
Each object in the Objects l ist will b e associated
w ith the delegate in the same position in the
Delegates list. If necessary, reorder either list
manually by highlighting entries and using the
Shift Up/Shift Down buttons; these are the
arrow buttons between t he two lists.
7. Click Alig n Objects with Delegates to align each
object with its corresponding delegate.
The objects on the Objects list are moved and
rotated to align w ith delegates. Each object’s
local Y axis points in the delegate’s forward
direction.
8. Click Link Objects to Delegates.
9. Click OK to exit.
To a ss ociate bipeds wi th delega tes:
1.
Set up a crowd simulation with a crowd helper
and delegates.
2. Create several bipeds, one for each delegate.
3. Select the crowd helper, a nd access the Modify
panel.
