This is a command from NifSE.
Syntax
(matrix:localRotation) NiAVObjectGetLocalRotation short:nifID short:blockID (matrix:localRotation) NiAVObjGetLocRot short:nifID short:blockID
Returns the matrix of the local rotation of the specified NiAVObject-derived block. The default value of blockID is 0, referring to the root NiNode, which is derived from NiAVObject. Therefore, this function can be used with the default argument when referring to the root node.
The matrix is a 3x3 array of floats, and is compatible with OBSE's linear algebra functions.
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.
