Guidelines on working with Configuration File (WIP)

using UnityEngine; //Telling unity its going to use its functions

#if UNITY_EDITOR // From the start of the if to the end of the if, it will only run this code using UnityEditor; // if its running Unity Editor and not a build/release executable. #endif

using System.Collections; // This is telling unity to gather the collection types which are using System.Collections.Generic; // types of object that contain multiple objects of a user defined type

using Xml = System.Xml; // Since we want to write a xml file we will call a class

using ConfigWriter = System.Xml.XmlWriter; // Tells unity ConfigWriter is of System.Xml's XmlWriter type

using ConfigReader = System.Xml.XmlDocument; // Saves ConfigReader as type of XmlDocument

public class Config : MonoBehaviour { // Unity reads this as script config uses mono functionality begins

`private string configPath = "Assets/config.xml";` // Saves text in configPath for later use

`static public Dictionary<string, string[]> colorsDictionary = new Dictionary<string, string[]>();`
    //This creates a Dictionary that will be used to store colors.

`void Start () {`  // When the config script starts being used start doing the code bellow

             // Verifies if files exist on configPath (the folder path we set config file to save
             // and returns the answer if true or false, then if it is false executes the code
             // that is inside the {}

                    // Creates a new xml file writer

		`settings.Indent = true;`//Set file indentation

		`string levelsPath = "Assets/scenes/";` //Set the path to where levels are stored

                    //Gets the name of each level and saves it
