一：功能

1.实例化

//设置插件在菜单栏的位置   和快捷键      [MenuItem("YCC's Tools/模型更改/更改父物体和测量长度 %W")]    //实例化窗体      static void Init()    {        myTools window = (myTools)EditorWindow.GetWindow(typeof(myTools));        window.titleContent.text = "更改父物体/测长";        window.Show();    }

 

 

2.选项卡制作

//用GUI画出窗体的空间布局      void OnGUI()    {        toolbarOption = GUILayout.Toolbar(toolbarOption, toolbarTexts);        switch (toolbarOption)        {            case 0:                fnChangeParent();                break;            case 1:                fnLength();                break;        }    }

 

 

3.多个物体更改模型父物体

 

void fnChangeParent()    {        GUILayout.BeginHorizontal("box");        GUILayout.Label("父物体：", EditorStyles.boldLabel);        ObjParent = EditorGUILayout.ObjectField(ObjParent, typeof(Transform)) as Transform;        GUILayout.EndHorizontal();        GUILayout.BeginHorizontal("box");        iChildCount = Selection.transforms.Length;//获取当前鼠标选中的物体个数        if (Selection.transforms.Length > 0)        {            GUILayout.Label("当前选中子物体个数："+iChildCount, EditorStyles.boldLabel);            if (GUILayout.Button("应用"))            {                if (ObjParent != null)                {                    for (int i = 0; i < iChildCount; i++)                    {                        if (Selection.transforms[i].parent != ObjParent)                            Selection.transforms[i].parent = ObjParent;                    }                    EditorUtility.DisplayDialog("提示", "已更换父物体", "确定");//显示对话框 DisplayDialog (title : string, message : string, ok : string, cancel : string = "") : bool                }                else                    this.ShowNotification(new GUIContent("当前没有父物体！"));//显示通知            }        }        else            GUILayout.Label("当前没有选中子物体" , EditorStyles.boldLabel);        GUILayout.EndHorizontal();    }

 

 

 

4.测量两个物体在场景中的距离

void fnLength()    {        GUILayout.BeginHorizontal("box");        GUILayout.Label("测量基准物体1：", EditorStyles.boldLabel);        T1 = EditorGUILayout.ObjectField(T1, typeof(Transform)) as Transform;        GUILayout.EndHorizontal();        GUILayout.BeginHorizontal("box");        GUILayout.Label("测量参考物体2：", EditorStyles.boldLabel);        T2 = EditorGUILayout.ObjectField(T2, typeof(Transform)) as Transform;        GUILayout.EndHorizontal();        GUILayout.BeginHorizontal();        if (T1 != null && T2 != null)        {            Debug.DrawLine(T1.position, T2.position, Color.red);            //if (GUILayout.Button("查    寻"))            //{              fDistance = Vector3.Distance(T1.position, T2.position);            //}            GUILayout.Label("距离：", EditorStyles.boldLabel);            EditorGUILayout.FloatField(fDistance, EditorStyles.boldLabel);        }        GUILayout.EndHorizontal();    }

 

 

二：注意

1.重绘

//在OnInspectorUpdate上调用重绘，因为它在窗口上较少重绘，就好象是OnGUI/Update    void OnInspectorUpdate()    {        Repaint();//重绘    }

 

2.错误

 出现错误： Invalid editor window UnityEditor.FallbackEditorWindow   解决方法：Layout-> Revert Factory Settings
