C# =>public float magneticHeading;

Description 描述

The heading in degrees relative to the magnetic North Pole. (Read Only)
相对于磁北极的航向，单位度。(只读)

The value in this property is always measured relative to the top of the screen in its current orientation. The heading of magnetic north is not exactly the same as true geographical north - to get the exact heading, use the trueHeading property.
在当前的方向，该属性值总是相对于屏幕顶端。磁北的航向并不是与真正的地理的磁北极一样——要得到精确的航向，使用trueHeading属性。

JavaScript:

  function Update () {
		// Orient an object to point to magnetic north.
		transform.rotation = Quaternion.Euler(0, -Input.compass.magneticHeading, 0);
	}

C#:

  function Update () {
		// Orient an object to point to magnetic north.
		transform.rotation = Quaternion.Euler(0, -Input.compass.magneticHeading, 0);
	}
