IU Prefabs list from xml string, Help me

Morpheus-Tao · Sep 9, 2015

Hi, I am days that I try in every way to make a list of messages, but I can not imagine the mechanism.

Then I created a php function that draws from the message list and returns this structure in xml:

Code (CSharp):

<messages>

<count value="2">

<message>

<idmsg>1</idmsg>

<sender>Morpheus Tao</sender>

<title>Title text message</title>

<body>Message</body>

<readed>0</readed>

<date>2015-09-06 01:52:30</date>

</message>

<message>

<idmsg>2</idmsg>

<sender>Tirion Namir</sender>

<title>Title text message</title>

<body>Message</body>

<readed>0</readed>

<date>2015-09-06 01:52:30</date>

</message>

</count>

</messages>

With this function:

Code (CSharp):

public IEnumerator LoadMessage(string username){

string MessageUrl= config.ServerUri + "Etc....";

var www = new WWW (MessageUrl);

if (!www.isDone)

yield return www;

if (!string.IsNullOrEmpty (www.error)) {

Debug.LogException(new Exception("NetworkManager.Messages error" + www.error));

IsLoggedIn = true;

yield break;

}

Debug.Log ("result:" + www.text);

XmlDocument xmlDoc = new XmlDocument ();

xmlDoc.LoadXml (www.text);

int count = 0;

XmlNodeList xnl = xmlDoc.SelectNodes("/messages/count");

foreach (XmlNode node in xnl)

{

Debug.Log( count = Convert.ToInt32(node.Attributes["value"].InnerText));

if (count != 0)

{

XmlNodeList xnl2 = xmlDoc.SelectNodes("/messages/count/message");

foreach (XmlNode node2 in xnl2)

{

//Test Debug info loaded

Debug.Log(node2["idmsg"].InnerText);

Debug.Log(node2["sender"].InnerText);

Debug.Log(NetworkSecurity.Decrypt(node2["title"].InnerText));

Debug.Log(NetworkSecurity.Decrypt(node2["body"].InnerText));

Debug.Log(node2["readed"].InnerText);

Debug.Log(node2["date"].InnerText);

}

}

}

}

Now I would like the messages loaded from XML
They were listed in the UI of my game (with canvas)
example:

How do I program the UI so that it works, you can help me, maybe with some examples?
Still they are not very practical new UI 4.6

Code (csharp):

using UnityEngine;

using UnityEngine.UI; // need this to use Text type

using System.Collections;

using System.Collections.Generic; // needed for using list, you might not need this one

public class TestScript : MonoBehaviour

{

List<string> myMessages; // I need something to show

public Transform canvasElementToPutMessagesIn;

public Transform messageTextPrefab;

void Start()

{

myMessages = new List<string>();

// impart wise message on the world... :P

myMessages.Add("hello");

myMessages.Add("world");

myMessages.Add("my");

myMessages.Add("name");

myMessages.Add("is");

myMessages.Add("bob");

// it isn't really :D

// the bit you need to look at

foreach(string message in myMessages)

{

Transform clone = Instantiate(messageTextPrefab);

clone.SetParent(canvasElementToPutMessagesIn);

// UI elements must be parented to a canvas, or a descendant of a canvas or they wont show

clone.GetComponent<Text>().text = message;

}

}

}

messageTextPrefab just needs to be a standard Text ui element (i.e. create in the hierarchy via the r-click menu and drag it into the project as a prefab), or you can style it as you would like.

if you add a "layout" component onto the UI element you target as the container for the messages you can style them as you need to.

Thanks for the help, do experiments and tell you how it went

Hi LeflyRighty Thanks for help,
I was able to perform the function private message with your advice, but I would have another question.
As you can see from the screenshot it all works perfectly, except that does not list in the right posts.

Correct order:

Code (CSharp):

<messages>

<count value="3">

<message>

<idmsg>1</idmsg>

<sender>Ashma Daeva</sender>

<title>5H/pt/8kK3wI40fwiaxP0r5IsSrE1t6fhN2tjVYSngM=</title>

<body>8/+Qod7sfRZL6eE32rl7wg==</body>

<sendlv>3</sendlv>

<readed>0</readed>

<date>2015-09-10 20:59:35</date>

</message>

<message>

<idmsg>2</idmsg>

<sender>Ashma Daeva</sender>

<title>KmZNz46Ny4CiNeCeti2zVQ==</title>

<body>h99DsUhkdI4n7zNA7WxXrA==</body>

<sendlv>3</sendlv>

<readed>0</readed>

<date>2015-09-10 20:59:31</date>

</message>

<message>

<idmsg>3</idmsg>

<sender>Ashma Daeva</sender>

<title>e8vv+nuyuGG1X5MIFbAxZw==</title>

<body>

<sendlv>3</sendlv>

<readed>0</readed>

<date>2015-09-10 20:58:55</date>

</message>

</count>

</messages>

Result:

How could I improve the script so that it works well?

Code (CSharp):

using UnityEngine;

using UnityEngine.UI; // need this to use Text type

using System.Collections;

using System.Collections.Generic; // needed for using list, you might not need this one

public class pm_MessageListUI : MonoBehaviour {

public GameObject MessageUIPrefab = null;

public Transform MessageList = null;

public Text MessageCountText = null;

public Text senderText = null;

public Text titleText = null;

public Text bodyText = null;

public Text statusText = null;

public Text dateText = null;

pm_MessageClass rdr;

// Use this for initialization

void Awake ()

{

rdr = new pm_MessageClass("http://link"); //Not work ssl :'(

// now display the feed items

foreach(pm_MessageClass.messages itm in rdr.rowNews.message)

{

GameObject f = Instantiate(MessageUIPrefab) as GameObject;

f.transform.SetParent(MessageList, false);

senderText.text = itm.sender;

titleText.text = itm.title;

statusText.text = itm.readed;

dateText.text = itm.date;

// UI elements must be parented to a canvas, or a descendant of a canvas or they wont show

}

}

}

This is the class:

Code (CSharp):

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

using System.Xml;

using SecureConnection;

public class pm_MessageClass{

XmlTextReader PMReader;

XmlDocument PMDoc;

XmlNode nodePM;

XmlNode nodeMessages;

XmlNode nodeMessage;

public channel rowNew;

public struct channel

{

public string count;

public List<messages> message;

}

public struct messages

{

public string idmsg;

public string sender;

public string title;

public string body;

public string readed;

public string date;

}

// our constructor takes the URL to the feed

public pm_MessageClass (string feedURL){

// setup the messages structure

rowNew = new channel ();

// make the list available to write to

rowNew.message = new List<messages>();

PMReader = new XmlTextReader (feedURL);

PMDoc = new XmlDocument ();

PMDoc.Load (PMReader);

// Loop for the <messages> tag

for (int i = 0; i < PMDoc.ChildNodes.Count; i++)

{

// If it is the messages tag

if (PMDoc.ChildNodes[i].Name == "messages") {

// <messages> tag found

nodePM = PMDoc.ChildNodes[i];

}

}

// Loop for the <count> tag

for (int i = 0; i < nodePM.ChildNodes.Count; i++) {

// If it is the count tag

if (nodePM.ChildNodes[i].Name == "count") {

// <count> tag found

nodeMessages = nodePM.ChildNodes[i];

}

}

for (int i = 0; i < nodeMessages.ChildNodes.Count; i++) {

if (nodeMessages.ChildNodes[i].Name == "message") {

nodeMessage = nodeMessages.ChildNodes[i];

messages pm = new messages();

pm.idmsg = nodeMessage["idmsg"].InnerText;

pm.sender = nodeMessage["sender"].InnerText;

pm.title = NetworkSecurity.Decrypt(nodeMessage["title"].InnerText);

pm.body = NetworkSecurity.Decrypt(nodeMessage["body"].InnerText);

pm.readed = nodeMessage["readed"].InnerText;

pm.date = nodeMessage["date"].InnerText;

rowNew.message.Add(pm);

}

}

}

}

I wanted to use "public IEnumerator LoadMessage (string username)"
but then I would not know how to call up the list with the function Messages
StartCoroutine (NetworkManager.messages (link));
so I might as well use SSL when I am not allowed
