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
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
