1. 简介：

IMGUI是代码驱动gui系统，由 OnGUI 函数驱动：

void OnGUI() {
if (GUILayout.Button("Press Me")){
Debug.Log("Hello!");
}
}

复制代码

IMGUI常用于：
创建 in-game debugging displays and tools；
为组件创建自定义inspector；
创建editor windows and tools；
2. IMGUI底子：

OnGUI()函数在脚本激活时每帧调用；

using UnityEngine;
[ExecuteAlways]
public class TestGUI : MonoBehaviour
{
private void OnGUI()
{
GUI.Box(new Rect(10, 10, 100, 90), "Loader Menu");
if(GUI.Button(new Rect(20, 40, 80, 20), "Button 1"))
{
Debug.Log("Button 1");
}
if (GUI.Button(new Rect(20, 70, 80, 20), "Button 2"))
{
Debug.Log("Button 2");
}
}
}

复制代码

3. 调用函数来绘制控件：
(GUI/GUILayout).Type (Rect, Content)；
定义 Rect 时，坐标系基于屏幕左上角，可使用 Screen.width 和 Screen.height ；
Content范例：
string；
Texture2D；
GUIContent；

GUI.Box(new Rect(10, 10, 100, 50), icon);
GUI.Box(new Rect(10, 60, 100, 50), new GUIContent("text", icon));
GUI.Box(new Rect(10, 110, 100, 50), new GUIContent("text", icon, "This is the tooltip"));
GUI.Button(new Rect(10, 160, 100, 20), new GUIContent("Click me", "This is the tooltip"));
GUI.Label(new Rect(10, 180, 100, 20), GUI.tooltip); //显示当前的tooltip内容

复制代码

3. IMGUI控件：

Label：

GUI.Label(new Rect(100, 100, 100, 30), "show text");

复制代码

Button：

if(GUI.Button(new Rect(100, 100, 100, 30), "button"))
{
Debug.Log("Click button");
}

复制代码

RepeatButton：

类似 Button，只是点击时一直返回 true；
TextField：

str = GUI.TextField(new Rect(100, 100, 100, 30), str);

复制代码

单行文本输入；
TextArea：

str = GUI.TextArea(new Rect(100, 100, 100, 100), str);

复制代码

多行文本输入；
Toggle：

toggleVal = GUI.Toggle(new Rect(100, 100, 100, 30), toggleVal, "Toggle");

复制代码

Toolbar：

一行单选按钮，toolbarInt 用来记录选择的按钮索引；

private int toolbarInt = 0;
private string[] toolbarStrings = { "Toolbar1", "Toolbar2", "Toolbar3" };
void OnGUI()
{
toolbarInt = GUI.Toolbar(new Rect(100, 100, 300, 30), toolbarInt, toolbarStrings);
}

复制代码

SelectionGrid：

多行Toolbar；

private int selectionIndex = 0;
private string[] selectionStrings = { "Toolbar1", "Toolbar2", "Toolbar3", "Toolbar4" };
void OnGUI()
{
selectionIndex = GUI.SelectionGrid(new Rect(100, 100, 300, 60), selectionIndex, selectionStrings, 2);
}

复制代码

HorizontalSlider：

水平滑动条

private float sliderValue = 0.0f;
void OnGUI()
{
sliderValue = GUI.HorizontalSlider(new Rect(100, 100, 100, 30), sliderValue, 0.0f, 10.0f);
}

复制代码

VerticalSlider：

垂直滑动条；

private float sliderValue = 0.0f;
void OnGUI()
{
sliderValue = GUI.VerticalSlider(new Rect(100, 100, 100, 30), sliderValue, 0.0f, 10.0f);
}

复制代码

HorizontalScrollbar：

类似 Slider，用于导航 ScrollView 控件，有一个额外参数控制旋钮宽度；

private float scrollValue = 0.0f;
void OnGUI()
{
scrollValue = GUI.HorizontalScrollbar(new Rect(100, 100, 100, 30), scrollValue, 1, 0.0f, 10.0f);
}

复制代码

VerticalScrollbar：

类似 HorizontalScrollbar；
ScrollView：

private Vector2 scrollPosition = Vector2.zero;
void OnGUI()
{
//第一个参数指定可视区域，第三个参数指定在滚动列表内的大小
scrollPosition = GUI.BeginScrollView(new Rect(100, 100, 100, 100), scrollPosition, new Rect(0, 0, 400, 400));
GUI.Label(new Rect(0, 0, 400, 400), "text");
GUI.EndScrollView();
}

复制代码

Window：

可拖动的容器；

private Rect windowRect = new Rect(100, 100, 100, 100);
void OnGUI()
{
windowRect = GUI.Window(0, windowRect, WindowFunction, "My Window");
}
void WindowFunction(int id)
{
GUI.Label(new Rect(10, 20, 100, 30), "text");
GUI.DragWindow(); //让window可拖动
}

复制代码

GUI.changed：
检测用户是否有操作；

selectIndex = GUI.Toolbar(new Rect(100, 100, 200, 30), selectIndex, options);
if(GUI.changed)
{
Debug.Log("selectIndex = " + selectIndex);
}

复制代码

4. 使用GUIStyles样式化控件：

GUIStyles 控制控件的外观显示；

GUISkins 包罗一系列 GUIStyles；

所有控件可设置一个可选的 GUIStyle；

//指定 GUIStyle 的名字 button
GUI.Label(new Rect(100, 100, 100, 30), "text", "button");

复制代码

在脚本中声明一个序列化的GUIStyle ，查看属性：

public GUIStyle style;
void OnGUI()
{
//指定 GUIStyle 的名字 button
GUI.Label(new Rect(100, 100, 100, 30), "text", style);
}

复制代码

设置GUISkin：

public GUISkin skin;
void OnGUI()
{
GUI.skin = skin;
//绘制
//...
//恢复默认skin
GUI.skin = null; //
}

复制代码

改变GUIStyle：

GUIStyle style = GUI.skin.GetStyle("label");
style.fontSize = 30;
GUI.Label(new Rect(100, 100, 400, 100), "text1");
style.fontSize = 50;
GUI.Label(new Rect(100, 150, 400, 100), "text2");

复制代码

5. IMGUI Layout 模式：

固定结构和自动结构：

要使用自动结构，使用 GUILayout 代替GUI；
可以在 OnGUI() 函数中同时使用两种结构方式，但是两种结构相互独立；
GUILayout 不必要指定 Rect；

// Fixed Layout
GUI.Button(new Rect(25, 25, 100, 30), "I am a Fixed Layout Button");
// Automatic Layout
GUILayout.Button("I am an Automatic Layout Button");

复制代码

固定结构 Group：

Group内的控件将基于组的左上角定位；

GUI.BeginGroup(new Rect(Screen.width / 2 - 50, Screen.height / 2 - 50, 100, 100));
GUI.Box(new Rect(0, 0, 100, 100), "Group is here");
GUI.Button(new Rect(10, 40, 80, 30), "Click me");
GUI.EndGroup();

复制代码

可以嵌套使用Group，可获取裁剪效果：

// background image that is 256 x 32
public Texture2D bgImage;
// foreground image that is 256 x 32
public Texture2D fgImage;
// a float between 0.0 and 1.0
public float playerEnergy = 1.0f;
//使用默认style绘制box
public GUIStyle style = new GUIStyle();
void OnGUI()
{
if(bgImage == null || fgImage == null)
{
return;
}
GUI.BeginGroup(new Rect(300, 300, 256, 32));
// 绘制背景
GUI.Box(new Rect(0, 0, 256, 32), bgImage, style);
// 通过 playerEnergy 控制显示大小，达到裁剪效果
GUI.BeginGroup(new Rect(0, 0, playerEnergy * 256, 32));
GUI.Box(new Rect(0, 0, 256, 32), fgImage, style);
GUI.EndGroup();
GUI.EndGroup();
}

复制代码

自动结构 Area：

类似固定结构 Group;
定义屏幕的一块区域来包罗 GUILayout 控件，控件基于 Area 的左上角定位；

GUILayout.Button("I am not inside an Area");
GUILayout.BeginArea(new Rect(Screen.width / 2, Screen.height / 2, 300, 300));
GUILayout.Button("I am completely inside an Area");
GUILayout.EndArea();

复制代码

注意Area里控件的宽度将被拉伸到与Area一样；
自动结构 Horizontal and Vertical Group：

使用自动结构时，控件默认从上往下一个接一个；
为了修改这一行为，提供了Horizontal 和 Vertical Group；
Horizontal Group 里的控件被水平摆放；
GUILayout.BeginHorizontal(), GUILayout.EndHorizontal()
Vertical Group 里的控件被垂直摆放；
GUILayout.BeginVertical(), and GUILayout.EndVertical()

GUILayout.BeginArea(new Rect(400, 400, 200, 100));
GUILayout.BeginHorizontal();
GUILayout.Button("Button\nfirst");
GUILayout.BeginVertical();
GUILayout.Button("Button2");
GUILayout.Label("Label");
GUILayout.EndVertical();
GUILayout.EndHorizontal();
GUILayout.EndArea();

复制代码

GUILayoutOptions ：

使用 GUILayoutOptions 覆盖一些自动结构参数；

GUILayout.BeginArea(new Rect(100, 50, Screen.width - 200, Screen.height - 100));
GUILayout.Button("I am a regular Automatic Layout Button");
GUILayout.Button("My width has been overridden", GUILayout.Width(95));
GUILayout.EndArea();

复制代码

6. 使用 IMGUI 扩展编辑器：

1. 创建自定义 Editor Window：

1. 创建脚本继续 EditorWindow：

using UnityEditor;
using UnityEngine;
public class MyWindow : EditorWindow
{
private void OnGUI()
{
}
}

复制代码

2. 显示window：

using UnityEditor;
using UnityEngine;
public class MyWindow : EditorWindow
{
[MenuItem("Window/My Window")]
public static void ShowWindow()
{
EditorWindow.GetWindow(typeof(MyWindow));
}
private void OnGUI()
{
}
}

复制代码

3. 实现 gui：
EditorGUI 和 EditorGUILayout 提供了额外的控件；

using UnityEditor;
using UnityEngine;
public class MyWindow : EditorWindow
{
string myString = "Hello World";
bool groupEnabled;
bool myBool = true;
float myFloat = 1.23f;
[MenuItem("Window/My Window")]
public static void ShowWindow()
{
EditorWindow.GetWindow(typeof(MyWindow));
}
private void OnGUI()
{
GUILayout.Label("Base Settings", EditorStyles.boldLabel);
myString = EditorGUILayout.TextField("Text Field", myString);
groupEnabled = EditorGUILayout.BeginToggleGroup("Optional Settings", groupEnabled);
myBool = EditorGUILayout.Toggle("Toggle", myBool);
myFloat = EditorGUILayout.Slider("Slider", myFloat, -3, 3);
EditorGUILayout.EndToggleGroup();
}
}

复制代码

2. 自定义 Inspector：

1. 自定义 GUI of Serializable class：

using System;
using UnityEngine;
public enum PersonLevel { A, B, C}
[Serializable]
public class Person
{
public string name;
public int age;
public PersonLevel personLevel;
}
public class PersonInfo : MonoBehaviour
{
public Person person;
public Person[] persons;
}

复制代码

（默认显示）
使用 Property Drawer 来控制其在 Inspector 上的显示：

using UnityEditor;
using UnityEngine;
[CustomPropertyDrawer(typeof(Person))]
public class PersonDrawer : PropertyDrawer
{
public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
// Using BeginProperty / EndProperty on the parent property means that
// prefab override logic works on the entire property.
EditorGUI.BeginProperty(position, label, property);
// Draw label
position = EditorGUI.PrefixLabel(position, GUIUtility.GetControlID(FocusType.Passive), label);
// Don't make child fields be indented
var indent = EditorGUI.indentLevel;
EditorGUI.indentLevel = 0;
// Calculate rects
var nameRect = new Rect(position.x, position.y, 30, position.height);
var ageRect = new Rect(position.x + 35, position.y, 50, position.height);
var personLevelRect = new Rect(position.x + 90, position.y, position.width - 90, position.height);
// Draw fields - pass GUIContent.none to each so they are drawn without labels
EditorGUI.PropertyField(nameRect, property.FindPropertyRelative("name"), GUIContent.none);
EditorGUI.PropertyField(ageRect, property.FindPropertyRelative("age"), GUIContent.none);
EditorGUI.PropertyField(personLevelRect, property.FindPropertyRelative("personLevel"), GUIContent.none);
// Set indent back to what it was
EditorGUI.indentLevel = indent;
EditorGUI.EndProperty();
}
}

复制代码

2. 使用 Property Attribute 自定义脚本成员 GUI：

创建 Attribute：

using UnityEngine;
public class MyRangeAttribute : PropertyAttribute
{
public float min;
public float max;
public MyRangeAttribute(float min, float max)
{
this.min = min;
this.max = max;
}
}

复制代码

对 Attribute 进行自定义绘制：

using UnityEditor;
using UnityEngine;
//对MyRangeAttribute
[CustomPropertyDrawer(typeof(MyRangeAttribute))]
public class RangeDrawer : PropertyDrawer
{
public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
// First get the attribute since it contains the range for the slider
MyRangeAttribute range = (MyRangeAttribute)attribute;
// Now draw the property as a Slider or an IntSlider based on whether it's a float or integer.
if (property.propertyType == SerializedPropertyType.Float)
EditorGUI.Slider(position, property, range.min, range.max, label);
else if (property.propertyType == SerializedPropertyType.Integer)
EditorGUI.IntSlider(position, property, (int)range.min, (int)range.max, label);
else
EditorGUI.LabelField(position, label.text, "Use MyRange with float or int.");
}
}

复制代码

（注意，为了性能考虑，EditorGUILayout 不可在 PropertyDrawer 中使用）
使用 Attribute：

using UnityEngine;
public class TestAttribute : MonoBehaviour
{
[MyRange(1.5f, 35f)]
public float fValue;
}

复制代码

3. Component 自定义编辑器：

创建 component：

using UnityEngine;
[ExecuteInEditMode]
public class LookAtPoint : MonoBehaviour
{
public Vector3 lookAtPoint = Vector3.zero;
void Update()
{
transform.LookAt(lookAtPoint);
}
}

复制代码

创建组件自定义编辑器：

using UnityEditor;
[CustomEditor(typeof(LookAtPoint))]
[CanEditMultipleObjects]
public class LookAtPointEditor : Editor
{
LookAtPoint targetComp;
SerializedProperty lookAtPoint;
void OnEnable()
{
lookAtPoint = serializedObject.FindProperty("lookAtPoint");
}
public override void OnInspectorGUI()
{
targetComp = target as LookAtPoint;
serializedObject.Update();
EditorGUILayout.PropertyField(lookAtPoint);
serializedObject.ApplyModifiedProperties();
}
}

复制代码

通过 OnSceneGUI 往 Scene View 中添加编辑器代码：

using UnityEngine;
using UnityEditor;
[CustomEditor(typeof(LookAtPoint))]
[CanEditMultipleObjects]
public class LookAtPointEditor : Editor
{
private void OnSceneGUI()
{
LookAtPoint t = (LookAtPoint)target;
//使用 Handles 类来实现3D场景编辑控制
EditorGUI.BeginChangeCheck();
//给定位置，在场景中画中控制轴，拖动的话，返回变化的pos
Vector3 pos = Handles.PositionHandle(t.lookAtPoint, Quaternion.identity);
if (EditorGUI.EndChangeCheck())
{
Undo.RecordObject(target, "Move point");
t.lookAtPoint = pos;
t.Update();
}
}
}

复制代码

如果要在场景中添加 GUI，使用 Handles.BeginGUI() and Handles.EndGUI()；
4. TreeView ：

是一个 IMGUI 控件，用于显示分层数据，可展开和折叠；
使用 TreeView 创建高度自定义的列表视图和多列表格；
按行渲染，每行代表一个 TreeViewItem，包罗父节点和子节点的信息；
TreeView 有一个潜伏的根 TreeViewItem，是所有其他 item的根；
重要的类和方法：

类 TreeViewState：
包罗交互的状态信息，可序列化，以便在编辑器编译和进入Play模式时生存数据；
类 TreeViewItem：
包罗每个 TreeView item 的数据，在 TreeView 中必要一个唯一 id；
depth 属性用来视觉缩进；
抽象方法 BuildRoot：
TreeView 类的抽象方法，每次调用 TreeView 的 Reload 方法就会触发；
用于创建 root item；
对于简单树，可创建所有的 TreeViewItem；
对于复杂树，通过覆写 BuildRows 来创建当前必要的行；
虚方法 BuildRows：
默认实现创建整个树；
可覆写只创建展开的行；

初始化 TreeView：

调用 Reload 方法来初始化；
两种方式设置 TreeView：
1. 在 BuildRoot 中创建整个树；
2. 在 BuildRoot 中只创建根，然后在 BuildRows 中只创建展开的 items；
Example 1: A simple TreeView：

using System.Collections.Generic;
using UnityEditor.IMGUI.Controls;
public class SimpleTreeView : TreeView
{
public SimpleTreeView(TreeViewState state) : base(state)
{
Reload();
}
protected override TreeViewItem BuildRoot()
{
// BuildRoot is called every time Reload is called to ensure that TreeViewItems
// are created from data. Here we create a fixed set of items. In a real world example,
// a data model should be passed into the TreeView and the items created from the model.
// This section illustrates that IDs should be unique. The root item is required to
// have a depth of -1, and the rest of the items increment from that.
var root = new TreeViewItem { id = 0, depth = -1, displayName = "Root" };
var allItems = new List<TreeViewItem>
{
new TreeViewItem {id = 1, depth = 0, displayName = "Animals"},
new TreeViewItem {id = 2, depth = 1, displayName = "Mammals"},
new TreeViewItem {id = 3, depth = 2, displayName = "Tiger"},
new TreeViewItem {id = 4, depth = 2, displayName = "Elephant"},
new TreeViewItem {id = 5, depth = 2, displayName = "Okapi"},
new TreeViewItem {id = 6, depth = 2, displayName = "Armadillo"},
new TreeViewItem {id = 7, depth = 1, displayName = "Reptiles"},
new TreeViewItem {id = 8, depth = 2, displayName = "Crocodile"},
new TreeViewItem {id = 9, depth = 2, displayName = "Lizard"},
};
// Utility method that initializes the TreeViewItem.children and .parent for all items.
SetupParentsAndChildrenFromDepths(root, allItems);
// Return root of the tree
return root;
}
}

复制代码

另一种方式添加 Item：

protected override TreeViewItem BuildRoot()
{
// BuildRoot is called every time Reload is called to ensure that TreeViewItems
// are created from data. Here we create a fixed set of items. In a real world example,
// a data model should be passed into the TreeView and the items created from the model.
// This section illustrates that IDs should be unique. The root item is required to
// have a depth of -1, and the rest of the items increment from that.
var root = new TreeViewItem { id = 0, depth = -1, displayName = "Root" };
//不指定depth，通过 TreeViewItem.AddChild 来添加节点
var animals = new TreeViewItem { id = 1, displayName = "Animals" };
root.AddChild(animals);
var mammals = new TreeViewItem { id = 2, displayName = "Mammals" };
animals.AddChild(mammals);
mammals.AddChild(new TreeViewItem { id = 3, displayName = "Tiger" });
mammals.AddChild(new TreeViewItem { id = 4, displayName = "Elephant" });
mammals.AddChild(new TreeViewItem { id = 5, displayName = "Okapi" });
mammals.AddChild(new TreeViewItem { id = 6, displayName = "Armadillo" });
var reptiles = new TreeViewItem { id = 7, displayName = "Reptiles" };
animals.AddChild(reptiles);
reptiles.AddChild(new TreeViewItem { id = 8, displayName = "Crocodile" });
reptiles.AddChild(new TreeViewItem { id = 9, displayName = "Lizard" });
SetupDepthsFromParentsAndChildren(root);
// Return root of the tree
return root;
}

复制代码

使用 EditorWindow 显示 TreeView：

using UnityEditor;
using UnityEditor.IMGUI.Controls;
using UnityEngine;
public class SimpleTreeViewWindow : EditorWindow
{
// SerializeField is used to ensure the view state is written to the window
// layout file. This means that the state survives restarting Unity as long as the window
// is not closed. If the attribute is omitted then the state is still serialized/deserialized.
[SerializeField]
TreeViewState m_TreeViewState;
//The TreeView is not serializable, so it should be reconstructed from the tree data.
SimpleTreeView m_SimpleTreeView;
void OnEnable()
{
// Check whether there is already a serialized view state (state
// that survived assembly reloading)
if (m_TreeViewState == null)
m_TreeViewState = new TreeViewState();
//创建 TreeView
m_SimpleTreeView = new SimpleTreeView(m_TreeViewState);
}
void OnGUI()
{
//绘制 TreeView
m_SimpleTreeView.OnGUI(new Rect(0, 0, position.width, position.height));
}
// Add menu named "My Window" to the Window menu
[MenuItem("TreeView Examples/Simple Tree Window")]
static void ShowWindow()
{
// Get existing open window or if none, make a new one:
var window = GetWindow<SimpleTreeViewWindow>();
window.titleContent = new GUIContent("SimpleTreeView Window");
window.Show();
}
}

复制代码

Example 2: A multi-column TreeView：

最终效果：

（列Header鼠标右键菜单）
EditorWindow：

using System;
using System.Collections.Generic;
using UnityEditor.Callbacks;
using UnityEditor.IMGUI.Controls;
using UnityEngine;
namespace UnityEditor.TreeViewExamples
{
class MultiColumnWindow : EditorWindow
{
[NonSerialized] bool m_Initialized;
// Serialized in the window layout file so it survives assembly reloading
[SerializeField] TreeViewState m_TreeViewState;
[SerializeField] MultiColumnHeaderState m_MultiColumnHeaderState;
SearchField m_SearchField;
MultiColumnTreeView m_TreeView;
MyTreeAsset m_MyTreeAsset;
[MenuItem("TreeView Examples/Multi Columns")]
public static MultiColumnWindow GetWindow ()
{
var window = GetWindow<MultiColumnWindow>();
window.titleContent = new GUIContent("Multi Columns");
window.Focus();
window.Repaint();
return window;
}
//双击资源时触发
[OnOpenAsset]
public static bool OnOpenAsset (int instanceID, int line)
{
var myTreeAsset = EditorUtility.InstanceIDToObject (instanceID) as MyTreeAsset;
if (myTreeAsset != null)
{
var window = GetWindow ();
window.SetTreeAsset(myTreeAsset);
return true;
}
return false; // we did not handle the open
}
void SetTreeAsset (MyTreeAsset myTreeAsset)
{
m_MyTreeAsset = myTreeAsset;
m_Initialized = false;
}
// TreeView 显示区域
Rect multiColumnTreeViewRect
{
get { return new Rect(20, 30, position.width-40, position.height-60); }
}
// 搜索显示区域
Rect toolbarRect
{
get { return new Rect (20f, 10f, position.width-40f, 20f); }
}
//底部工具栏区域
Rect bottomToolbarRect
{
get { return new Rect(20f, position.height - 18f, position.width - 40f, 16f); }
}
public MultiColumnTreeView treeView
{
get { return m_TreeView; }
}
void InitIfNeeded ()
{
if (!m_Initialized)
{
// Check if it already exists (deserialized from window layout file or scriptable object)
if (m_TreeViewState == null)
m_TreeViewState = new TreeViewState();
//创建 HeaderState，包含各列头部ui相关显示
bool firstInit = m_MultiColumnHeaderState == null;
var headerState = MultiColumnTreeView.CreateDefaultMultiColumnHeaderState(multiColumnTreeViewRect.width);
//应用本地数据
if (MultiColumnHeaderState.CanOverwriteSerializedFields(m_MultiColumnHeaderState, headerState))
MultiColumnHeaderState.OverwriteSerializedFields(m_MultiColumnHeaderState, headerState);
m_MultiColumnHeaderState = headerState;
//根据 HeaderState 创建 MultiColumnHeader
var multiColumnHeader = new MyMultiColumnHeader(headerState);
if (firstInit)
multiColumnHeader.ResizeToFit ();
var treeModel = new TreeModel<MyTreeElement>(GetData());
//根据 TreeViewState，MultiColumnHeader， TreeModel 创建 TreeView
m_TreeView = new MultiColumnTreeView(m_TreeViewState, multiColumnHeader, treeModel);
//搜索输入框
m_SearchField = new SearchField();
m_SearchField.downOrUpArrowKeyPressed += m_TreeView.SetFocusAndEnsureSelectedItem;
m_Initialized = true;
}
}
// 获取列表数据
IList<MyTreeElement> GetData ()
{
if (m_MyTreeAsset != null && m_MyTreeAsset.treeElements != null && m_MyTreeAsset.treeElements.Count > 0)
return m_MyTreeAsset.treeElements;
// generate some test data
return MyTreeElementGenerator.GenerateRandomTree(130);
}
// 选择某个资源时触发
void OnSelectionChange ()
{
if (!m_Initialized)
return;
var myTreeAsset = Selection.activeObject as MyTreeAsset;
if (myTreeAsset != null && myTreeAsset != m_MyTreeAsset)
{
m_MyTreeAsset = myTreeAsset;
