Unity EditorWindow 筆記

 

一：功能

1.實例化

 //設置插件在菜單欄的位置   和快捷鍵  
    [MenuItem("YCC's Tools/模型更改/更改父物體和測量長度 %W")]
    //實例化窗體  
    static void Init()
    {
        myTools window = (myTools)EditorWindow.GetWindow(typeof(myTools));
        window.titleContent.text = "更改父物體/測長";
        window.Show();
    }

 

 

2.選項卡制作

 //用GUI畫出窗體的空間布局  
    void OnGUI()
    {
        toolbarOption = GUILayout.Toolbar(toolbarOption, toolbarTexts);
        switch (toolbarOption)
        {
            case 0:
                fnChangeParent();
                break;
            case 1:
                fnLength();
                break;
        }
    }

 

 

3.多個物體更改模型父物體

 

void fnChangeParent()
    {
        GUILayout.BeginHorizontal("box");
        GUILayout.Label("父物體：", EditorStyles.boldLabel);
        ObjParent = EditorGUILayout.ObjectField(ObjParent, typeof(Transform)) as Transform;
        GUILayout.EndHorizontal();
        GUILayout.BeginHorizontal("box");
        iChildCount = Selection.transforms.Length;//獲取當前鼠標選中的物體個數
        if (Selection.transforms.Length > 0)
        {
            GUILayout.Label("當前選中子物體個數："+iChildCount, EditorStyles.boldLabel);
            if (GUILayout.Button("應用"))
            {
                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", "已更換父物體", "確定");//顯示對話框 DisplayDialog (title : string, message : string, ok : string, cancel : string = "") : bool
                }
                else
                    this.ShowNotification(new GUIContent("當前沒有父物體！"));//顯示通知
            }
        }
        else
            GUILayout.Label("當前沒有選中子物體" , EditorStyles.boldLabel);
        GUILayout.EndHorizontal();
    }

 

 

 

4.測量兩個物體在場景中的距離

 void fnLength()
    {
        GUILayout.BeginHorizontal("box");
        GUILayout.Label("測量基准物體1：", EditorStyles.boldLabel);
        T1 = EditorGUILayout.ObjectField(T1, typeof(Transform)) as Transform;
        GUILayout.EndHorizontal();
        GUILayout.BeginHorizontal("box");
        GUILayout.Label("測量參考物體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    尋"))
            //{  
            fDistance = Vector3.Distance(T1.position, T2.position);
            //}
            GUILayout.Label("距離：", EditorStyles.boldLabel);
            EditorGUILayout.FloatField(fDistance, EditorStyles.boldLabel);
        }
        GUILayout.EndHorizontal();
    }

 

 

二：注意

1.重繪

 //在OnInspectorUpdate上調用重繪，因為它在窗口上較少重繪，就好象是OnGUI/Update
    void OnInspectorUpdate()
    {
        Repaint();//重繪
    }

 

2.錯誤

 出現錯誤： Invalid editor window UnityEditor.FallbackEditorWindow   解決方法：Layout-> Revert Factory Settings
