UNITY_ARCore：localEulerAngles始终提供0值

Question

与ARCore合作在UNITY中创建指南针。 播放器是AR核心设备：第一人称相机。 任何人都可以解决始终获得0的问题。 Click here for Screenshot

using UnityEngine.UI;
using UnityEngine;
public class Compass : MonoBehaviour
{
    public RawImage CompassImage;
    public Transform Player;
    public Text CompassDirectionText;

    public void Update()
    {
        CompassImage.uvRect = new Rect(Player.localEulerAngles.y / 360, 0, 1, 1);

        Vector3 forward = Player.transform.forward;

        forward.y = 0;

        float headingAngle = Quaternion.LookRotation(forward).eulerAngles.y;
        headingAngle = 5 * (Mathf.RoundToInt(headingAngle / 5.0f));

        int displayangle;
        displayangle = Mathf.RoundToInt(headingAngle);

        CompassDirectionText.text = headingAngle.ToString ();
    }
}
