STransform

public class STransform
{
    public SVector position = new SVector();
    //the examples currently don't use scale/rotation but you may
    public SVector scale = new SVector();
    public SVector rotation = new SVector();//replace for whatevers relavent for you
}

Soft float version of a Transform. Transforms in games usually have position, scale, rotation as a minimum. You’re welcome to add more to here if you like though. As stated in the comment, currently the example is not taking use of scale or rotation.
