A SetFormation Behavior (crowdBeSetFormation) enables a group of
Entities of the same Group Entity Type
to keep a formation. Formations are defined using a population tool.
the formation is not moving, and must be
placed exactly where slots are (no moving direction management). This is
the right choice for crowd merging in a logo shape for example.
Moving Way
Controls which side of formation will face
the moving direction. There are 3 modes :
Toward World X Axis : formation "front" moving direction is world X
Axis.
Toward Poptool Transform X Axis : formation "front" moving direction
is Population Tool locator X Axis
Toward Mean orientation (default) : formation "front" moving
direction is the mean orientation of Population Tool particles.
Slots Assignment Mode
The slots assignment mode offers different
methods for different needs :
Direct : slots will be assigned arbitrarily. This is suitable if you
want to use a formation on a group done with the same Population Tool,
else it will lead to an arbitrary assignment without specific
rules.
Sort By X : slots and entity positions are sorted by their X, then
assigned "lesser X entity to lesser X slot", etc.
Sort By Z : slots and entity positions are sorted by their Z, then
assigned "lesser Z entity to lesser Z slot", etc.
Bidding Algorithm (Fast) : compute the smallest mean error to
allocate slots to entities. This should only be used for groups of less
than 1000 entities for computation time reasons. Using it on bigger
groups may lead to unresponsive Maya.
Bidding Algorithm (Precise) : compute the smallest mean error to
allocate slots to entities, and also favor the smallest standard
deviation for entities displacement. This should only be used for groups
of less than 500 entities for computation time reasons. Using it on
bigger groups may lead to unresponsive Maya.
