The RotationToLocal method of the Transform struct converts a given world rotation to a local rotation relative to the transform's current orientation. This is useful when you need to understand how a global rotation would be represented in the local space of an object.
To use the RotationToLocal method, you need to have a Transform instance. You can then call this method by passing a reference to a Rotation object that represents the world rotation you want to convert. The method will return a new Rotation object that represents the equivalent rotation in the local space of the transform.
// Assume 'transform' is an instance of Transform Rotation worldRotation = new Rotation(0, 90, 0); // Example world rotation Rotation localRotation = transform.RotationToLocal(ref worldRotation); // 'localRotation' now contains the rotation in the local space of 'transform'.
