pymel.core.effects.radial

radial(*args, **kwargs)

A radial field pushes objects directly towards or directly away from it, like a magnet. 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.

Flags:

Long name (short name)		Argument Types	Properties
attenuation (att)		float
	Attentuation rate of field
magnitude (m)		float
	Strength of field.
maxDistance (mxd)		float
	Maximum distance at which field is exerted. -1 indicates that the field has no maximum distance.
name (n)		unicode
	name of field
perVertex (pv)		bool
	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 froce is exerted only from the geometric center of the set of points.
position (pos)		float, float, float
	Position in space where you want to place a field. The field 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.
torusSectionRadius (tsr)		float
type (typ)		float
	Type of radial field (0 - 1). This controls the algorithm by which the field is attenuated. Type 1, provided for backward compatibility, specifies the same algorithm as Alias | Wavefront Dynamation. A value between 0 and 1 yields a linear blend. Flag can have multiple arguments, passed either as a tuple or a list.
volumeExclusion (vex)		bool
volumeOffset (vof)		float, float, float
volumeShape (vsh)		unicode
volumeSweep (vsw)		float

Derived from mel command maya.cmds.radial

Example:

import pymel.core as pm

pm.radial( 'particle1', m=5.0, mxd=2.0 )
# Creates a radial field with magnitude 5.0 and maximum distance 2.0,
# and adds it to the list of fields particle1 owns.

pm.radial( pos=(2, 0, 4 ))
# Creates a radial field at position (0,2,4) in world coordinates,
# with default magnitude(1.0), attentuation (1.0),
# and max distance (5.0).

pm.radial( 'radialField1', e=True, att=0.98 )
# Edits the attenuation value of the field named radialField1

pm.radial( 'radialField1', q=True, m=True )
# Queries radialField1 for its magnitude.

pm.radial( 'radialField1', e=True, mxd=10.0 )
# Changes the maximum distance of the field called
# "radialField1" to 10.0.

pm.radial( m=2.0 )
# Creates a radial field with magnitude 2.0 for every active selection.
# If no there are active
# selections, creates such a field at world position (0,0,0).
