Description 描述

The raw geomagnetic data measured in microteslas. (Read Only)
原始地磁数据，单位微特斯拉。(只读)

The compass is actually a magnetometer that measures the magnetic field in the device's XYZ coordinates - in the absence of a stronger magnet, it will measure the Earth's field from which the compass heading can be found. This property can be used if you want to make non-standard use of the compass (eg, find the heading from the X or Z axis of the device).
指南针实际上是在设备的XYZ坐标上测量磁场的磁力仪，当没有强大的磁力时，它将以指南针航向发现的地球磁场计算。如果你想使用非标准的指南针，可以使用这个属性(例如，找到这个设备的X或Z轴航向)。

JavaScript:

function OnGUI() {
		GUILayout.Label("Magnetometer reading: " + Input.compass.rawVector.ToString());
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnGUI() {
        GUILayout.Label("Magnetometer reading: " + Input.compass.rawVector.ToString());
    }
}
