goal is undoable, queryable, and NOT editable.
Specifies the given objects as being goals for the given particle
object. If the goal objects are geometry, each particle in the
particle object will each try to follow or match its position to
that of a certain vertex/CV/lattice point of the goal. If the goal
object is another particle object, each particle will try to follow
a paricle of the goal. In any other case, all the particles will
try to follow the current location of the goal object's transform.
You can get this latter behavior for a geometry or particle object
too by using -utr true. The goal weight can be keyframed. It lives
on the particle object to which the goal was added and is a
multi-attribute.
In query mode, return type is based on queried flag.

-goal(-g) |
string |
   |
|
This flag specifies string to be a goal of the particle object
on the command line or the currently selected particle object. This
flag can be used multiple times to specify multiple goals for a
particle object. Query is for use by the attribute editor. |
|
-weight(-w) |
float |
|
|
This specifies the goal weight as a value from 0 to 1. A value
of 0 means that the goal's position will have no effect on the
particle object, while a weight of 1 will make the particle object
try to follow the goal object exactly. This flag can only be passed
once and sets the weight for every goal passed with the -g/-goal
flag. |
|
-index(-i) |
|
|
|
Returns array of multi-attribute indices for the goals.
Intended for use by the Attribute Editor. |
|
-useTransformAsGoal(-utr) |
boolean |
|
|
Use transform of specified object instead of the shape.
Meaningful only for particle and geometry objects. Can only be
passed once, applies to all objects passed with -g. |

goal -g surface1 -w .75 Particle;
// This command assigns surface1 as a goal of Particle with a goal
// weight of 0.75.
goal -g surface1 -w .75 -utr true Particle;
// This command assigns the transform of surface1 as a goal of Particle
// with a goal weight of 0.75.
goal -g camera1 -w .75 Particle;
// This command assigns the transform of camera1 as a goal of Particle
// with a goal weight of 0.75. The -utr flag is not relevant because
// only the transform can be used for any object other than geometry
// or particles.
