在專案開發中經常需要儲存場景中物體的旋轉，位置，大小。為了每次儲存成統一的格式方便複用，給Transfrom加入設定和獲取的拓展方法。關於拓展方法的可以推薦 拓展方法 這篇文章。下面是改功能的實現：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

/// <summary>
/// 類必須是靜態類，
/// 另外擴充套件方法（Extension Methods）必須也是靜態方法，
/// 方法的引數中必須要有被擴充套件類作為其中一個引數，
/// 此引數前面用this關鍵字修飾。
/// </summary>
public static class TransformExtension {

    /// <summary>
    /// 根據字串設定Transform的位置旋轉和縮放
    /// </summary>
    /// <param name="transform"></param>
    /// <param name="info">px,py,pz;rx,ry,rz;sx,sy,sz</param>
    public static void SetTransformByString(this Transform transform, string info)
    {
        string[] infos = info.Split(';');
        if (infos.Length >= 3)
        {
            transform.localPosition = GetVectorFromString(infos[0]);
            transform.localEulerAngles = GetVectorFromString(infos[1]);
            transform.localScale = GetVectorFromString(infos[2]);
        }
    }

    /// <summary>
    /// 獲取transform 9軸資訊的字串
    /// </summary>
    /// <param name="transform"></param>
    /// <returns>px,py,pz;rx,ry,rz;sx,sy,sz</returns>
    public static string GetTransformDetails(this Transform transform)
    {
        string result = "";
        result += GetVectorString(transform.localPosition) + ";";
        result += GetVectorString(transform.localEulerAngles) + ";";
        result += GetVectorString(transform.localScale);

        return result;
    }

    public static Vector3 GetVectorFromString(string str)
    {
        Vector3 result = Vector3.zero;
        try
        {
            string[] temps = str.Split(',');
            result.x = float.Parse(temps[0]);
            result.y = float.Parse(temps[1]);
            result.z = float.Parse(temps[2]);
        }
        catch (Exception e)
        {
            throw e;
        }
        return result;
    }

    public static string GetVectorString(Vector3 vec)
    {
        string result = vec.x.ToString("0.00") + "," + vec.y.ToString("0.00") + "," + vec.z.ToString("0.00");

        return result;
    }
}
