unity ui toolkit

1、项目初始化，导入UI Builder

1.1 导入UI Builder

Unity版本2020及以上才支持，2020版本需要打开preview，才能使用

 1.2 创建编辑器面板

2、使用UI Builder搭建面板结构

2.1 参数设置修改的样式

3、在代码中使用控件，使用ObjectField和ListView

  1. using UnityEditor;
  2. using UnityEngine;
  3. using UnityEngine.UIElements;
  4. using UnityEditor.UIElements;
  5.  
  6.  
  7. public class TestWindow : EditorWindow
  8. {
  9.     private ObjectField objectField;
  10.  
  11.     [MenuItem("UI Toolkit Window/TestWindow")]
  12.     public static void ShowExample()
  13.     {
  14.         TestWindow wnd = GetWindow<TestWindow>();
  15.         wnd.titleContent = new GUIContent("TestWindow");
  16.     }
  17.  
  18.     public void CreateGUI()
  19.     {
  20.         // Each editor window contains a root VisualElement object
  21.         VisualElement root = rootVisualElement;
  22.  
  23.         // Import UXML
  24.         var visualTree = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/Scripts/UIToolKit/Editor/TestWindow.uxml");
  25.         VisualElement labelFromUXML = visualTree.Instantiate();
  26.         labelFromUXML.style.flexGrow = 1;
  27.         root.Add(labelFromUXML);
  28.  
  29.         //获取控件
  30.         objectField = root.Q<ObjectField>("ObjectField");
  31.         //设置控件参数
  32.         objectField.objectType = typeof(GameObject);
  33.  
  34.     }
  35. }
  1.         //获取控件
  2.         listView = root.Q<ListView>("ListView");
  3.         //listView组件单个item组件创建方法绑定
  4.         listView.makeItem = MakeListItem;
  5.         //listView组件单个item绑定数据
  6.         listView.bindItem = BindListItem;
  7.         //listView组件选中item改变事件
  8.         listView.onSelectionChange += OnSelectItem;
  9.  
  10.  
  11.     private void OnSelectItem(IEnumerable<object> obj)
  12.     {
  13.         foreach (var item in obj)
  14.         {
  15.             GameObject go = item as GameObject;
  16.             Selection.activeObject = item as GameObject;
  17.             /*
  18.             //nameText.value = go.name;
  19.             //posText.value = go.transform.localPosition;
  20.             
  21.             SerializedObject so = new SerializedObject(go);
  22.             nameText.Bind(so);
  24.             SerializedObject so2 = new SerializedObject(go.transform);
  25.             posText.Bind(so2);
  26.             */
  27.  
  28.             if(go.TryGetComponent<MyCube>(out comp))
  29.             {
  30.                 var so = new SerializedObject(comp);
  31.                 tempField.Bind(so);
  32.             }
  33.             else
  34.             {
  35.                 tempField.Unbind();
  36.             }
  37.  
  38.         }
  39.     }
  40.  
  41.     private void BindListItem(VisualElement ve, int index)
  42.     {
  43.         Label label = ve as Label;
  44.         var go = sceneObjects[index];
  45.         label.text = go.name;
  46.     }
  47.  
  48.     private VisualElement MakeListItem()
  49.     {
  50.         var label = new Label();
  51.         label.style.unityTextAlign = TextAnchor.MiddleLeft;
  52.         label.style.paddingLeft = 5;
  53.         return label;
  54.     }

4、数据绑定、事件监听

  1.         //数据绑定
  2.         nameText = root.Q<TextField>("NameText");
  3.         posText = root.Q<Vector3Field>("PosText");
  4.         nameText.bindingPath = "m_Name";
  5.         posText.bindingPath = "m_LocalPosition";
  6.  
  7.         tempField = root.Q<IntegerField>("TempField");
  8.         tempField.bindingPath = "Temp";
  9.  
  10.         //事件监听
  11.         tempTextField = root.Q<TextField>("TempTextField");
  12.         tempTextField.RegisterValueChangedCallback<string>(OnTempTextFieldValueChange);
  13.  
  14.     private void OnSelectItem(IEnumerable<object> obj)
  15.     {
  16.         foreach (var item in obj)
  17.         {
  18.             GameObject go = item as GameObject;
  19.             Selection.activeObject = item as GameObject;
  20.             /*
  21.             //nameText.value = go.name;
  22.             //posText.value = go.transform.localPosition;
  23.             
  24.             SerializedObject so = new SerializedObject(go);
  25.             nameText.Bind(so);
  27.             SerializedObject so2 = new SerializedObject(go.transform);
  28.             posText.Bind(so2);
  29.             */
  30.  
  31.             if(go.TryGetComponent<MyCube>(out comp))
  32.             {
  33.                 var so = new SerializedObject(comp);
  34.                 tempField.Bind(so);
  35.             }
  36.             else
  37.             {
  38.                 tempField.Unbind();
  39.             }
  40.  
  41.         }
  42.     }
  43.  
  44.     private void OnTempTextFieldValueChange(ChangeEvent<string> evt)
  45.     {
  46.          Debug.Log($"Old: {evt.previousValue},_____ New: {evt.newValue}");
  47.     }

5、USS样式、Debug调试

5.1 USS样式

5.2 Debug调试

6、UI复用到Inspect面板

6.1 将内容创建为创建为VisualElement子类

  1. using System.Collections;
  2. using System.Collections.Generic;
  3. using UnityEditor.UIElements;
  4. using UnityEditor;
  5. using UnityEngine;
  6. using UnityEngine.SceneManagement;
  7. using UnityEngine.UIElements;
  8.  
  9. public class SceneObjectPanel : VisualElement
  10. {

  12.     private ObjectField objectField;
  13.     private Button createBtn;
  14.     private Button refreshBtn;
  15.  
  16.     private ListView listView;
  17.     private TextField nameText;
  18.     private Vector3Field posText;
  19.  
  20.     public SceneObjectPanel()
  21.     {
  22.         // Each editor window contains a root VisualElement object
  23.         VisualElement root = this;
  24.  
  25.         // Import UXML
  26.         var visualTree = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/Scripts/UIToolKit/Editor/SceneObjectWindow.uxml");
  27.         //VisualElement labelFromUXML = visualTree.Instantiate();
  28.         //labelFromUXML.style.flexGrow = 1;
  29.         //root.Add(labelFromUXML);

 6.2 创建子类并使用

  1. using System.Collections;
  2. using System.Collections.Generic;
  3. using UnityEditor;
  4. using UnityEngine;
  5. using UnityEngine.UIElements;
  6.  
  7. [CustomEditor(typeof(MyCube))]
  8. public class MyCubeInspector : Editor
  9. {
  10.     public override VisualElement CreateInspectorGUI()
  11.     {
  12.         //var root = new VisualElement();
  13.         //root.Add(base.CreateInspectorGUI());
  14.         //var visualTree = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/Scripts/UIToolKit/Editor/SceneObjectWindow.uxml");
  15.         //VisualElement labelFromUXML = visualTree.Instantiate();
  16.         //labelFromUXML.style.flexGrow = 1;
  17.         //root.Add(labelFromUXML);
  18.  
  19.         //var bas = base.CreateInspectorGUI();
  20.         //root.Add(bas);
  21.         var root = new VisualElement();
  22.         root.Add(new IMGUIContainer(OnInspectorGUI));
  23.         root.Add(new SceneObjectPanel());
  24.  
  25.         return root;
  26.     }
  27. }
