Question

我试图用手机位置的Lat和Lon绘制标签。当我在电脑上调试时，我返回0,0。这是预料到的，因为我在没有电脑的电脑上全球定位系统。 PC构建确实绘制了标签。当我运行同一件事的android构建时。标签根本没有绘制 - 我假设因为它不能正常工作。我的androidmanifest.xml使用正确的权限正确设置。

这是我的GPS代码 - 它附在游戏对象上。

    using UnityEngine;
    using System.Collections;

    public class GPS : MonoBehaviour {


float lat ;
float lon ;
float alt ;
float horz ;
float time ;
public GUIStyle myGuiStyle_CORDS;

IEnumerator Start (){
    // First, check if user has location service enabled
    if (!Input.location.isEnabledByUser)

    // Start service before querying location
    Input.location.Start ();
    // Wait until service initializes
    int maxWait = 20;

    while (Input.location.status
           == LocationServiceStatus.Initializing && maxWait > 0) {
         yield return new WaitForSeconds(1);
        maxWait--;
    }
    // Service didn't initialize in 20 seconds
    if (maxWait < 1) {
        print ("Timed out");

    }
    // Connection has failed
    if (Input.location.status == LocationServiceStatus.Failed) {
        print ("Unable to determine device location");

    }
    // Access granted and location value could be retrieved
    else {
        iPhoneSettings.StartLocationServiceUpdates();


        print ("Location: " + Input.location.lastData.latitude + " " +
               Input.location.lastData.longitude + " " +
               Input.location.lastData.altitude + " " +
               Input.location.lastData.horizontalAccuracy + " " +
               Input.location.lastData.timestamp);
    }


    // Stop service if there is no need to query location updates continuously
    Input.location.Stop ();
}

void  OnGUI (){
    if (Globals.DisplayMode == "GPSST") {
        GUI.depth = 0;
        lon = Input.location.lastData.longitude;
        lat = Input.location.lastData.latitude;
        GUI.Label (new Rect (Globals.displayOffsetX + 5, 110, 100, 50), "" + Input.location.lastData.longitude, myGuiStyle_CORDS);
        GUI.Label (new Rect (Globals.displayOffsetX + 5, 130, 100, 50), "" + Input.location.lastData.latitude, myGuiStyle_CORDS);


    }
}


}

Answer 1

可能的原因

1）您正在Start（）的最后一行停止位置服务。您是否忘记了if语句中的return-commands？如：

if (!Input.location.isEnabledByUser)
    return;

if (maxWait < 1) {
    print ("Timed out");
    return;
}

2）你的第一个if语句与Input.location.Start（）

有关

if (!Input.location.isEnabledByUser)
    Input.location.Start()

也许这不是故意的？

3）OnGUI（）中的if语句返回false

Answer 2

首先，在Start（）方法

中激活您的位置服务

string message = "";
int maxwait = 20; //my top waiting time for location start
Input.location.Start(1,1);
While(Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
{
     new WaitForSeconds(1f);
     maxWait--;
}
if(Input.location.status == LocationServiceStatus.Failed)
   message = "Unable to run location";
else
{
   if(Input.location.status == LocationServiceStatus.Running)
      message = "location Running";
   else
      message = Input.location.status.ToString();
}

这是我使用的，也是激活指南针，但我认为你没有使用如果你是，那么只需添加Input.compass.enabled = true;你知道服务在哪里运行

祝你好运，编码愉快;

C＃GPS位置没有绘制到屏幕？
