setParticleAttr [-attribute string] [-floatValue float] [-object string] [-randomFloat float] [-randomVector float float float]
[-relative boolean] [-vectorValue float float float]
selectionList
setParticleAttr is undoable, NOT queryable, and NOT
editable.
This action will set the value of the chosen attribute for every
particle or selected component in the selected or passed particle
object. Components should not be passed to the command line. For
setting the values of components, the components must be selected
and only the particle object's names should be passed to this
action. If the attribute is a vector attribute and the -vv flag is
passed, then the three floats passed will be used to set the
values. If the attribute is a vector and the -fv flag is pass and
the -vv flag is not passed, then the float will be repeated for
each of the X, Y, and Z values of the attribute. Similarly, if the
attribute is a float attribute and a vector value is passed, then
the length of the vector passed will be used for the value. Note:
The attribute passed must be a Per-Particle attribute.

Argument types |
Properties |
-attribute(-at) |
string |
 |
|
Tells the action which attribute you want to set |
|
-floatValue(-fv) |
float |
|
|
Tells what you want the value to be set to of a float
attribute |
|
-vectorValue(-vv) |
float float float |
|
|
Tells what you want the value to be set to of a vector
attribute |
|
-randomFloat(-rf) |
float |
|
|
Tells the command to add a random value from -FLOAT to +FLOAT
to the results of each particle. The default is 0.0. |
|
-randomVector(-rv) |
float float float |
|
|
Tells the command to add a random value from
<<-x,-y,-z>> to <<x,y,z>> to the results of
each particle. The default 0 0 0. |
|
-relative(-r) |
boolean |
|
|
If this is set to TRUE (the default is FALSE), then the float
or vector value will be added to the current value for each
particle. |
|
-object(-o) |
string |
|
|
If this flag is passed and the STRING is the name of a particle
object's transform or shape, then ONLY that object will be edited,
ignoring the selection list or command line, and ALL of its
particles' values will be changed for the specified attribute. |
