Unity系统自带定位系统

之前发了一篇unity获取当前 IP地址所在的位置信息

而且是利用百度的接口返回结果的:链接

今天这是unity系统内部主要应用LocationService 和 LocationInfo这二个类

相关API详见官方文档地址https://docs.unity3d.com/ScriptReference/LocationService.html

我也相关的方法和属性也都尝试了一遍

代码如下:

public class Test1 : MonoBehaviour {

    string GetGps;
    public Text ShowGPS;
    /// <summary>
    /// 初始化一次位置
    /// </summary>
    void Start()
    {
        StartCoroutine(StartGPS());
        GetGps = "N:" + Input.location.lastData.latitude + " E:" + Input.location.lastData.longitude;
        ShowGPS.text += GetGps + "\n" +  Input.location.lastData.altitude + "\n" + Input.location.lastData.horizontalAccuracy + "\n" +
        Input.location.lastData.horizontalAccuracy + "\n"+ " Time:" + Input.location.lastData.timestamp + "\n";
    }
    /// <summary>
    /// 刷新位置信息（按钮的点击事件）
    /// </summary>
    public void updateGps()
    {
        StartCoroutine(StartGPS());
        GetGps = "N:" + Input.location.lastData.latitude + " E:" + Input.location.lastData.longitude;
        ShowGPS.text += GetGps + "\n" + " Time:" +Input.location.lastData.altitude+"\n"+Input.location.lastData.horizontalAccuracy+"\n"+
        Input.location.lastData.horizontalAccuracy + "\n" + Input.location.lastData.timestamp+"\n"; 
    }
    /// <summary>
    /// 停止刷新位置（节省手机电量）
    /// </summary>
    public void StopGPS()
    {
        Input.location.Stop();
    }

    IEnumerator StartGPS()
    {
        // Input.location 用于访问设备的位置属性（手持设备）, 静态的LocationService位置  
        // LocationService.isEnabledByUser 用户设置里的定位服务是否启用  
        if (!Input.location.isEnabledByUser)
        {
            GetGps = "isEnabledByUser value is:" + Input.location.isEnabledByUser.ToString() + " Please turn on the GPS";
            ShowGPS.text += GetGps + "\n";
            yield return false;
        }

        // LocationService.Start() 启动位置服务的更新,最后一个位置坐标会被使用  
        Input.location.Start(10.0f, 10.0f);

        int maxWait = 20;
        while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
        {
            // 暂停协同程序的执行(1秒)  
            yield return new WaitForSeconds(1);
            maxWait--;
        }

        if (maxWait < 1)
        {
            GetGps = "Init GPS service time out";
            ShowGPS.text += GetGps + "\n";
            yield return false;
        }

        if (Input.location.status == LocationServiceStatus.Failed)
        {
            GetGps = "Unable to determine device location";
            ShowGPS.text += GetGps + "\n";
            yield return false;
        }
        else
        {
            GetGps = "N:" + Input.location.lastData.latitude + " E:" + Input.location.lastData.longitude;
            GetGps = GetGps + " Time:" + Input.location.lastData.timestamp;
            yield return new WaitForSeconds(20);
        }
    }
}

官网的API都这在了
