load line from a text file and separate it

If I were you, I think I would define an XML format for the questions, and then have the answers be child tags of each question. A child tag would then have two attributes, one with the answer text, and another with a boolean True/False indicating whether that particular answer was correct or not.

Here's an example of what such an XML file COULD look like:

<?xml version="1.0" encoding="utf-8" ?>
<Questions>
  <Question Text="The country called the Land Of Rising Sun is ?">
    <Answer Text="China" Correct="False"></Answer>
    <Answer Text="Japan" Correct="True"></Answer>
    <Answer Text="France" Correct="False"></Answer>
    <Answer Text="UK" Correct="False"></Answer>
  </Question>
  <Question Text="What is the common name for ascorbic acid ?">
    ...(Answer tags)
  </Question>
</Questions>

Then, in your script, you load the file using this simple command:

System.Xml.XmlDocument questions = new System.Xml.XmlDocument();
questions.Load("Questions.xml");

Assuming you call the file "Questions.xml", of course. You then have an xml document with nodes and everything that you can traverse in code. Here's an example that generates buttons out of the answers:

// Grab the second node (The first is an XmlDeclaration) foreach (XmlNode xmlNode in questions.ChildNodes[1].ChildNodes) { // Put the question's text attribute in a label GUILayout.Label(xmlNode.Attributes["Text"].Value);

 // For each of the answers in the question node
 foreach (XmlNode answer in xmlNode.ChildNodes)
 {
     // Make a button that you can click to select that answer
     if (GUILayout.Button(answer.Attributes["Text"].Value))
     {
         // If clicked, check that node's Correct-attribute to see if it was correct
         if (answer.Attributes["Correct"].Value == "True")
         {
             // YAY, that was correct
         }
         else
         {
             // Wrong answer
         }
     }
 }            

First of all to design the xml file as you want.

 <levels>  
   <level>  
     <name>Level 1 (xml)</name>  
     <tutorial>Try comes close to all four objects. (xml)</tutorial>  
     <object name="Cube"> Hi, I'm a cube! (xml) </object>  
     <object name="Cylinder"> Hi, I'm a Cylinder! (xml) </object>  
     <object name="Capsule"> Hi, I'm a Capsule! (xml) </object>  
     <object name="Sphere"> Hi, I'm a Sphere! (xml)</object>  
     <finaltext>Very Good! (xml)</finaltext>  
   </level>  
   <level>  
     <name>Level 2 (xml)</name>  
     <tutorial>Try comes close to all four objects, again. (xml)</tutorial>  
     <object name="Cube"> Hi, I'm a cube in the level 2! (xml)</object>  
     <object name="Cylinder"> Hi, I'm a Cylinder in the level 2! (xml)</object>  
     <object name="Capsule"> Hi, I'm a Capsule in the level 2! (xml)</object>  
     <object name="Sphere"> Hi, I'm a Sphere in the level 2! (xml)</object>  
     <finaltext>Congratulations! (xml)</finaltext>  
   </level>  
 </levels>

Any node "level" can represents a question for your game.

Try to study this method: http://unitynoobs.blogspot.com/2011/02/xml-loading-data-from-xml-file.html

 public void GetLevel()  
  {  
   XmlDocument xmlDoc = new XmlDocument(); // xmlDoc is the new xml document.  
   xmlDoc.LoadXml(GameAsset.text); // load the file.  
   XmlNodeList levelsList = xmlDoc.GetElementsByTagName("level"); // array of the level nodes.  
    
   foreach (XmlNode levelInfo in levelsList)  
   {  
    XmlNodeList levelcontent = levelInfo.ChildNodes;  
    obj = new Dictionary<string,string>(); // Create a object(Dictionary) to colect the both nodes inside the level node and then put into levels[] array.  
      
    foreach (XmlNode levelsItens in levelcontent) // levels itens nodes.  
    {  
     if(levelsItens.Name == "name")  
     {  
      obj.Add("name",levelsItens.InnerText); // put this in the dictionary.  
     }  
       
     if(levelsItens.Name == "tutorial")  
     {  
      obj.Add("tutorial",levelsItens.InnerText); // put this in the dictionary.  
     }  
       
     if(levelsItens.Name == "object")  
     {  
      switch(levelsItens.Attributes["name"].Value)  
      {  
       case "Cube": obj.Add("Cube",levelsItens.InnerText);break; // put this in the dictionary.  
       case "Cylinder":obj.Add("Cylinder",levelsItens.InnerText); break; // put this in the dictionary.  
       case "Capsule":obj.Add("Capsule",levelsItens.InnerText); break; // put this in the dictionary.  
       case "Sphere": obj.Add("Sphere",levelsItens.InnerText);break; // put this in the dictionary.  
      }  
     }  
       
     if(levelsItens.Name == "finaltext")  
     {  
      obj.Add("finaltext",levelsItens.InnerText); // put this in the dictionary.  
     }  
    }  
    levels.Add(obj); // add whole obj dictionary in the levels[].  
   }  
  } 

And to get the values:

 string lvlName = "";  
   levels[actualLevel-1].TryGetValue("name",out lvlName);  
     
   string tutorial = "";  
   levels[actualLevel-1].TryGetValue("tutorial",out tutorial);  
     
   levels[actualLevel-1].TryGetValue("Cube",out Cube_Character);  
   levels[actualLevel-1].TryGetValue("Cylinder",out Cylinder_Character);  
   levels[actualLevel-1].TryGetValue("Capsule",out Capsule_Character);  
   levels[actualLevel-1].TryGetValue("Sphere",out Sphere_Character);  
     
   string finaltext = "";  
   levels[actualLevel-1].TryGetValue("finaltext",out finaltext);  

Note: actualLevel is just a int value, you can increment it and pass with your answers.

I am a bit confused about how to access different nodes ([actualLevel-1])

1. I would like to know how to access the level 2 node node.

2. I would like to access the level 2 node

Thanks

,If I wanted to access the level 2 node and drill into object cylinder for example. What code would I need. I have this running but the array containing what looks like a range [actualLevel-1] I am confused about. Thanks
