Synopsis

pointOnPolyConstraint [-layer string] [-maintainOffset] [-name string] [-offset float float float] [-remove] [-skip string] [-targetList] [-weight float] [-weightAliasList] [target...] [object]

pointOnPolyConstraint is undoable, queryable, and editable.

Constrain an object's position to the position of the target object or to the average position of a number of targets. A pointOnPolyConstraint takes as input one or more "target" DAG transform nodes at which to position the single "constraint object" DAG transform node. The pointOnPolyConstraint positions the constrained object at the weighted average of the world space position target objects.

Return value

string[] Name of the created constraint node

In query mode, return type is based on queried flag.

Flags

layer, maintainOffset, name, offset, remove, skip, targetList, weight, weightAliasList
Long name (short name) Argument types Properties
-name(-n) string createqueryedit
Sets the name of the constraint node to the specified name. Default name is constrainedObjectName_constraintType
-weight(-w) float createqueryedit
Sets the weight value for the specified target(s). If not given at creation time, the default value of 1.0 is used.
-remove(-rm) edit
removes the listed target(s) from the constraint.
-targetList(-tl) query
Return the list of target objects.
-weightAliasList(-wal) query
Returns the names of the attributes that control the weight of the target objects. Aliases are returned in the same order as the targets are returned by the targetList flag
-layer(-l) string createedit
Specify the name of the animation layer where the constraint should be added.
-offset(-o) float float float createqueryedit
Sets or queries the value of the offset. Default is 0,0,0.
-maintainOffset(-mo) create
The offset necessary to preserve the constrained object's initial position will be calculated and used as the offset.
-skip(-sk) string createeditmultiuse
Specify the axis to be skipped. Valid values are "x", "y", "z" and "none". During creation, "none" is the default. This flag is multi-use.

MEL examples

// Position cube1 at the location of cone1.
pointOnPolyConstraint cone1 cube1;

// Uses the average of the position of cone1 and surf2.
pointOnPolyConstraint -w .1 cone1 surf2 cube2;

// Sets the weight for cone1's effect on cube2 to 10.
pointOnPolyConstraint -e -w 10. cone1 cube2;

// Removes surf2 from cube2's pointOnPolyConstraint
pointOnPolyConstraint -e -rm surf2 cube2;

// Adds surf3 to cube2's pointOnPolyConstraint with the default weight
pointOnPolyConstraint surf3 cube2;

// Constrain the y & z translation of sph2 to sph1
pointOnPolyConstraint -skip x sph1 sph2;
