This is a command from NifSE.

Syntax

(bool:success) NiAVObjectSetLocalRotation array_var:rotation short:nifID short:blockID
(bool:success) NiAVObjSetLocRot array_var:rotation short:nifID short:blockID

Sets the local rotation of the specified NiAVObject-derived block. Since blockID defaults to 0, the NIF's root NiNode, and NiNode is derived from NiAVObject, this function will change the local rotation of the NIF's root if called with no explicit blockID.

The passed array_var must be a 3×3 rotation matrix

Example[edit | edit source]

This script will rotate each of the root's children, which are NiAVObject blocks, 180° about the X axis. This will effectively flip the NIF upside-down.

array_var R
array_var children
array_var child
short nifID
short blockID
...
let R := GenerateRotationMatrix X 180
let children := NiNodeGetChildren nifID
foreach child <- children
  let blockID := *child
  let locRot := NiAVObjectGetLocalRotation nifID blockID

  let locRot := MatrixMultiply R locRot ; order matters

  NiAVObjectSetLocalRotation locRot nifID blockID
loop

-* Because OBSE Plug-Ins cannot currently accept arrays as arguments, this function takes 9 floats instead of one 3x3 matrix of floats. OBSE v1900 is expected to enable the acceptance of arrays, in which case this function will be deprecated in favor of the version that accepts the matrix. Backwards compatibility ''will'' be maintained however.
-* Due to Wiki software limitations, the syntax section cannot be written on one line. Furthermore, it would be hideous to attempt to read that way in any case. However, the CS '''requires''' that all 11 arguments appear on a single line.
