unity编辑器拓展二——一键调整scene中物件坐标朝向

1.描述

　　在项目中，我们遇到很多这种情况，美术制作的时候从来不管坐标朝向，真正使用起来就会有各种问题。

需要美术来调整坐标朝向的时候，物体数量很多，就会很麻烦，很枯燥的工作，还得耐主性子一个一个调整。

 

　　如图，我们今天要做的是不动任何物体的情况下，一键控制物体的坐标朝向

 2.步骤分析

　　1.绘制窗口部分

　　2.lab绘制

　　3.button绘制

　　4.功能实现

代码如下：

using System.Collections.Generic;using UnityEngine;using UnityEditor;public class SceneTool : EditorWindow{    [MenuItem("Owen/Tool")]    //绘制窗口    static void tranPoint()    {        SceneTool win = (SceneTool)EditorWindow.GetWindow(typeof(SceneTool), false, "Tool", false);        win.Show();    }    void OnGUI()    {        //设置字体类型        GUIStyle style1 = new GUIStyle();        //字体大小为15        style1.fontSize = 15;        //字体颜色为灰白色        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);        //垂直绘制        GUILayout.BeginHorizontal();        {            //lab的绘制            EditorGUILayout.LabelField("▼TransformDirection", style1);            //按钮的绘制            if (GUI.Button(new Rect(100, 40, 25, 25), "↑"))            {                if (Selection.activeGameObject)                {                    forward();                }            }            //坐标朝向-z方向 按钮触发            if (GUI.Button(new Rect(100, 100, 25, 25), "↓"))            {                if (Selection.activeGameObject)                    back();            }            //坐标朝向-x方向 按钮触发            if (GUI.Button(new Rect(70, 70, 25, 25), "←"))            {                if (Selection.activeGameObject)                    left();            }            //坐标朝向x方向 按钮触发            if (GUI.Button(new Rect(130, 70, 25, 25), "→"))            {                if (Selection.activeGameObject)                    right();            }        }        GUILayout.EndHorizontal();    }    //坐标朝向Z轴方向    void forward()    {        Transform parent = Selection.activeGameObject.transform;        if (parent != null)        {            if (parent.GetComponent<Renderer>())            {                GameObject parent02 = new GameObject(parent.name+"-Parent");
