ReadObject() static private méthode

Loads a Loksim3D object from a file.
static private ReadObject ( string FileName, System Encoding, ObjectManager LoadMode, bool ForceTextureRepeatX, bool ForceTextureRepeatY, double RotationX, double RotationY, double RotationZ ) : ObjectManager.StaticObject
FileName string The text file to load the animated object from. Must be an absolute file name.
Encoding System The encoding the file is saved in. If the file uses a byte order mark, the encoding indicated by the byte order mark is used and the Encoding parameter is ignored.
LoadMode ObjectManager The texture load mode.
ForceTextureRepeatX bool Whether to force TextureWrapMode.Repeat for the X-axis
ForceTextureRepeatY bool Whether to force TextureWrapMode.Repeat for the Y-axis
RotationX double
RotationY double
RotationZ double
