uniform( selectionList , [attenuation=float], [directionX=float], [directionY=float], [directionZ=float], [magnitude=float], [maxDistance=linear], [name=string], [perVertex=boolean], [position=[linear, linear,
linear]])
Note: Strings representing object names and
arguments must be separated by commas. This is not depicted in the
synopsis.
uniform is undoable, queryable, and editable.
A uniform field pushes objects in a fixed direction. The field
strength, but not the field direction, depends on the distance from
the object to the field location. The transform is the associated
dependency node. Use connectDynamic to cause the field to affect a
dynamic object. If fields are created, this command returns the
names of each of the fields. If a field was queried, the results of
the query are returned. If a field was edited, the field name is
returned. If object names are provided or the active selection list
is non-empty, the command creates a field for every object in the
list and calls addDynamic to add it to the object. If the list is
empty, the command defaults to -pos 0 0 0. Setting the -pos flag
with objects named on the command line is an error.
In query mode, return type is based on queried flag.

Argument types |
Properties |
position(pos) |
[linear, linear, linear] |
   |
|
Position in space where you want to place a field. The gravity
then emanates from this position in space rather than from an
object. Note that you can both use -pos (creating a field at a
position) and also provide object names. |
|
magnitude(m) |
float |
|
|
|
attenuation(att) |
float |
|
|
Attentuation rate of field |
|
maxDistance(mxd) |
linear |
|
|
Maximum distance at which field is exerted. -1 indicates that
the field has no maximum distance. |
|
name(n) |
string |
|
|
|
perVertex(pv) |
boolean |
|
|
Per-vertex application. If this flag is set true, then each
individual point (CV, particle, vertex,etc.) of the chosen object
exerts an identical copy of the force field. If this flag is set to
false, then the force is exerted only from the geometric center of
the set of points. |
|
directionX(dx) |
float |
|
|
X-component of direction. |
|
directionY(dy) |
float |
|
|
Y-component of direction. |
|
directionZ(dz) |
float |
|
|
|

Flag can appear in Edit mode of command |

Flag can have multiple arguments, passed
either as a tuple or a list. |
