synopsis.
orientConstraint is undoable, queryable, and editable.
Constrain an object's orientation to match the orientation of the
target or the average of a number of targets. An orientConstraint
takes as input one or more "target" DAG transform nodes to control
the orientation of the single "constraint object" DAG transform The
orientConstraint orients the constrained object to match the
weighted average of the target world space orientations.

Argument types |
Properties |
name(n) |
string |
   |
|
Sets the name of the constraint node to the specified name.
Default name is constrainedObjectName_constraintType |
|
weight(w) |
float |
|
|
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) |
boolean |
|
|
removes the listed target(s) from the constraint. |
|
targetList(tl) |
boolean |
|
|
Return the list of target objects. |
|
weightAliasList(wal) |
boolean |
|
|
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 |
|
|
Specify the name of the animation layer where the constraint
should be added. |
|
offset(o) |
[float, float, float] |
|
|
Sets or queries the value of the offset. Default is 0,0,0. |
|
maintainOffset(mo) |
boolean |
|
|
The offset necessary to preserve the constrained object's
initial orientation will be calculated and used as the offset. |
|
skip(sk) |
string |
 |
|
Specify the axis to be skipped. Valid values are "x", "y", "z"
and "none". The default value in create mode is "none". This flag
is multi-use. |
|
createCache(cc) |
[float, float] |
|
|
This flag is used to generate an animation curve that serves as
a cache for the constraint. The two arguments define the start and
end frames.
The cache is useful if the constraint has multiple targets and the
constraint's interpolation type is set to "no flip". The "no flip"
mode prevents flipping during playback, but the result is dependent
on the previous frame. Therefore in order to consistently get the
same result on a specific frame, a cache must be generated. This
flag creates the cache and sets the constraint's interpolation type
to "cache". If a cache exists already, it will be deleted and
replaced with a new cache. |
|
deleteCache(dc) |
boolean |
|
|
Delete an existing interpolation cache. |
