using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using UnityEngine.SceneManagement;

public class TxtHandle : MonoBehaviour
{
    public static string[] configAry;
    static  List<string> list = new List<string>();
    string txtName = "configuration.txt";
    // Use this for initialization
    void Awake()
    {
        //StartCoroutine(WWWLoadTxtFile("/" + txtName));
        IOLoadTxtFile(txtName);

    }

    /// <summary>
    /// 檔案流讀取Txt檔案
    /// </summary>
    /// <param name="_filePath"></param>
    void IOLoadTxtFile(string _filePath)
    {
        //本地路徑
        var fileAddress = System.IO.Path.Combine(Application.streamingAssetsPath, _filePath);
        FileInfo fInfo0 = new FileInfo(fileAddress);
        string s = "";
        if (fInfo0.Exists)
        {

            s = r.ReadToEnd();
            configAry = s.Trim().Split(',');
            foreach (var item in configAry)
            {
                list.Add(item);
            }
        }
    }

    /// <summary>

    /// <returns></returns>
    public IEnumerator WWWLoadTxtFile(string _filePath)
    {
      
        print(Application.streamingAssetsPath);
        WWW www = new WWW(Application.streamingAssetsPath + _filePath);
        yield return www;
        if (www.error == null)
        {
            configAry = www.text.ToString().Trim().Split(',');
            foreach (var item in configAry)
            {

            }
            SceneManager.LoadScene(1);
        }
        else
        {
            Debug.Log(www.error);
        }
    }

    /// <summary>
    /// 根據傳過來的 string 返回 該字串在txt檔案中的下一個字串
    /// </summary>
    /// <param name="str"></param>
    /// <returns></returns>
    public static string TxtReadStr(string str)
    {
        string tempStr = null;
        if (list.Contains(str))
        {
            for (int i = 0; i < TxtHandle.configAry.Length; i++)
            {
                if (TxtHandle.configAry[i].Trim().Equals(str, StringComparison.CurrentCultureIgnoreCase))
                {
                    tempStr = TxtHandle.configAry[i + 1];
                    break;
                }
            }
        }
        else
        {
            Debug.Log("list not contain" + str);
        }
        return tempStr;
    }

}
