The RotationToLocal method of the Transform struct converts a given world rotation to a local rotation relative to the transform. This is useful when you need to understand how a rotation in the world space relates to the local space of an object.
To use the RotationToLocal method, you need to have a Transform instance and a Rotation object representing the world rotation you want to convert. The method will return a Rotation object that represents the equivalent rotation in the local space of the transform.
// Assume 'transform' is an instance of Transform // and 'worldRotation' is a Rotation object representing a world rotation. Rotation localRotation = transform.RotationToLocal(ref worldRotation); // 'localRotation' now contains the rotation in the local space of 'transform'.
