String to Float conversion not working :(

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class DatabasePosition : MonoBehaviour
5. {
6.     private string secretKey = "kep"; // Edit this value and make sure it's the same as the one stored on the server
7.     public string addPosURL = "url"; //be sure to add a ? to your url
8.     public string getPosXURL = "url";
9.     public string getPosYURL = "url";
10.     public string getPosZURL = "url";
11.     public MD5Test MD5Test;
12.  
13.     public string returnedvalueX;
14.     public string returnedvalueY;
15.     public string returnedvalueZ;
16.  
17.     public float xToFloat;
18.     public float yToFloat;
19.     public float zToFloat;
20.  
21.     public bool valueReturned = false;
22.  
23.     public GUIText test;
24.  
25.  
26.  
27.    
28.  
29.     public IEnumerator GetPlayerPosition(string user)
30.     {
31.         test.guiText.text = "Loading Position";
32.  
33.         string getposX_url = getPosXURL + "user=" + user;
34.         Debug.Log ("X Url" + getposX_url);
35.  
36.         string getposY_url = getPosYURL + "user=" + user;
37.         Debug.Log ("Y Url" + getposY_url);
38.  
39.         string getposZ_url = getPosZURL + "user=" + user;
40.         Debug.Log ("Z Url" + getposZ_url);
41.  
42.         WWW X_get = new WWW(getposX_url);
43.         yield return X_get;
44.  
45.         WWW Y_get = new WWW(getposY_url);
46.         yield return Y_get;
47.  
48.         WWW Z_get = new WWW(getposZ_url);
49.         yield return Z_get;
50.      
51.         if (X_get.error != null)
52.         {
53.             print("There was an error getting the high score: " + X_get.error);
54.         }
55.         else
56.         {
57.  
58.  
59.             returnedvalueX = X_get.text;
60.             returnedvalueY = Y_get.text;
61.             returnedvalueZ = Z_get.text;
62.  
63.             xToFloat = float.TryParse(returnedvalueX);
64.             yToFloat = float.TryParse(returnedvalueY);
65.             zToFloat = float.TryParse(returnedvalueZ);
66.  
67.  
68.  
69.             valueReturned = true;
70.         }
71.     }
72.  
73. }

Can someone help me out with this script? I have been trying to find answer for quite some time to no avail.

So a rundown of how this script is suppose to work.

It sends a username to my php script asking for the X Y and Z of the player. Long long story short it returns me a number which gets put into returnedvalue (XYZ respectively)

From this point I need to convert the web result (the returnedvalue variables), which is a string for some reason to a float to use as XYZ coordinates.

Can someone help me get this working?

 

TryParse returns a bool indicating success and takes an out parameter to which the value is applied if successful. So you'd want something like this

Code (csharp):

1.  
2. valueReturned = float.TryParse(returnedvalueX, out xToFloat) && float.TryParse(returnedvalueY, out yToFloat) && float.TryParse(returnedvalueZ, out zToFloat);
3.  

 

What error are you getting? I expected float.TryParse(float, out float) to need two parameters, not just one.

Code (csharp):

1. // Set xToFloat. If this is false, then we failed.
2. if (!float.TryParse(returnedvalueX, out xToFloat)) {
3.   Debug.Log("Unable to parse the string " + returnedvalueX + " to a float.");
4. }

 

Im getting a character unrecognized error and I found out why.... I tested it by hard coding it and it worked fine.

The problem is when the browser outputs... When I view it in the browser i get just number, However when it gets sent to unity it looks like this:

31
<!-- Hosting24 Analytics Code -->
<script type="text/javascript" src="http://stats.hosting24.com/count.php"></script>
<!-- End Of Analytics Code -->

I only want the "31" whats the rest of this stuff?!

EDIT:

I have confirmed it is client side, I accessed the script in my browser and hit ctrl+a then copied and pasted into notepad, it only pasted the number, Why is unity reading the rest of that stuff? am I outputting incorrectly in my php script?

EDIT:

Is there a way to check for that analytic stuff and simply delete it leaving just the number?

 

When you copy and paste, are you just pasting what you see in a browser? That other part is a script by your hosting service to keep track of page counts and it usually doesn't get displayed in a browser. I don't know if your hosting service does that automatically or if it's a setting on your hosting account.

EDIT: If you look at "Page Source" when you access the page in a web browser, is that script appearing there too? If so, then it's definitely server-side.

 

I was using the select all command. All I see on the page is the number. I have no doubt it is server side because im really new to php. Here is the script for getting the X value, am I calling stuff wrong? For some reason that While loop at the end seems unnecessary and might be causing the problem. Any thoughts?

PHP:

<?php
    // Send variables for the MySQL database class.
    $database = mysql_connect('host', 'user', 'pass') or die('Could not connect: ' . mysql_error());
    mysql_select_db('database') or die('Could not select database');

    $user = mysql_real_escape_string($_GET['user'], $database); 

$query  = "SELECT user, PlayerX  FROM Users WHERE user = '$user'";
$result = mysql_query($query) or die (mysql_error());

while($row = mysql_fetch_array($result))
{
    echo "{$row['PlayerX']}";


} 

         
?> 

 

Oh man, it's been a while since I dealt with php and SQL code. I'm not going to be able to help there!

I really think that 3 lines dealing with analytics is being added by your server and has nothing to do with your php/SQL script. I would guess that those 3 lines are being added to every single web page served on that web host.

If you do want to see the page source, I don't know what web browser you're using, but in Firefox I can just right click to bring up a menu and select "View Page Source".

 

Let me take a look, Im using 000webhost. Don't suppose you know how I would disable this?

 

You are correct, I viewed the source and I see this:

841.928
<!-- Hosting24 Analytics Code -->
<script type="text/javascript" src="http://stats.hosting24.com/count.php"></script>
<!-- End Of Analytics Code -->

 

Well, searching Google for "hosting24 analytics" brings this up as the first result. Interestingly, it's about 000webhost specifically.

EDIT: Maybe as a work around you can just strip everything after the first line of your string?

 

Ok I went into control panel and yes they were adding code to my stuff. Thanks so much! Would not have thought of that!

 

If I can disable it entirely will that be ok? or should i just try to remove it?

EDIT:

Disabled it entirely and the code works flawlessly, Thanks all for your suggestions!
