1.描述

　　在專案中，我們遇到很多這種情況，美術製作的時候從來不管座標朝向，真正使用起來就會有各種問題。

需要美術來調整座標朝向的時候，物體數量很多，就會很麻煩，很枯燥的工作，還得耐主性子一個一個調整。

　　如圖，我們今天要做的是不動任何物體的情況下，一鍵控制物體的座標朝向

 2.步驟分析

　　1.繪製視窗部分

　　2.lab繪製

　　3.button繪製

　　4.功能實現

程式碼如下：

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

public class SceneTool : EditorWindow
{
    [MenuItem("Owen/Tool")]
    //繪製視窗
    static void tranPoint()
    {
        SceneTool win = (SceneTool)EditorWindow.GetWindow(typeof(SceneTool), false, "Tool", false);
        win.Show();
    }
    void OnGUI()
    {
        //設定字型型別
        GUIStyle style1 = new GUIStyle();
        //字型大小為15
        style1.fontSize = 15;
        //字型顏色為灰白色
        style1.normal.textColor = new Color(0.7f, 0.7f, 0.7f);

        GUIStyle style2 = new GUIStyle();
        style2.fontSize = 13;
        style2.normal.textColor = new Color(0.7f, 0.7f, 0.7f);

        //垂直繪製
        GUILayout.BeginHorizontal();
        {
            //lab的繪製
            EditorGUILayout.LabelField("▼TransformDirection", style1);


            //按鈕的繪製
            if (GUI.Button(new Rect(100, 40, 25, 25), "↑"))
            {
                if (Selection.activeGameObject)
                {
                    forward();
                }
            }

            //座標朝向-z方向 按鈕觸發
            if (GUI.Button(new Rect(100, 100, 25, 25), "↓"))
            {
                if (Selection.activeGameObject)
                    back();
            }
            //座標朝向-x方向 按鈕觸發
            if (GUI.Button(new Rect(70, 70, 25, 25), "←"))
            {
                if (Selection.activeGameObject)
                    left();
            }
            //座標朝向x方向 按鈕觸發
            if (GUI.Button(new Rect(130, 70, 25, 25), "→"))
            {
                if (Selection.activeGameObject)
                    right();
            }
        }
        GUILayout.EndHorizontal();
    }

    //座標朝向Z軸方向
    void forward()
