Unity Editor Inspector界面编辑

一、继承MonoBehaviour

1、[Header(" ")] 标题

//Add a header above some fields in the Inspector.
[Header("Tittle")]
public string Str;

2、[Tooltip(" ")] 如果鼠标光标是在字段上，显示的说明文本

//Specify a tooltip for a field.
[Tooltip("This is a Tooltip")]
public string Str;

3、[Range(0, 5)] 将int、float变量限制在特定范围内，滑动条

//Attribute used to make a float or int variable in a script be restricted to a
//specific range.
[Range(0, 5)]
public int Int;
[Range(0, 5)]
public float Float;

4、[Multiline] 字符串多行文本显示

//Attribute used to make a string value be shown in a multiline textarea.
[Multiline]
public string Str;

5、[TextArea(2, 5)] 字符串多行文本显示，可以设置可现实的最大值和最小值的行数

//Attribute to make a string be edited with a height-flexible and scrollable 
//text area.
[TextArea(2, 5)]
public string Str;

6、[ContextMenu(" ")] 右键脚本添加菜单事件

//Adds the function to the context menu of the component.
[ContextMenu("QwQ")]
void HelloWorld(){Debug.Log("我发出了QwQ");}

7、[ContextMenuItem(" ", " ")] 右键变量添加菜单事件

//Use this attribute to add a context menu to a field that calls a named method.
[ContextMenuItem("ResetValue", "resetValue")]
public int A = 100;void resetValue()
{A = 50;
}

8、[HideInInspector] 在Inspector面板中隐藏

//Makes a variable not show up in the inspector but be serialized.
[HideInInspector]
public string Str;

9、[Serializable] 可序列化

[Serializable]
public class SerializableTest
{public int A = 5;public Color c = Color.white;
}public SerializableTest Test;

10、[Space(50)] 两个变量之间添加间距

//Use this DecoratorDrawer to add some spacing in the Inspector.
public string Str0;
[Space(50)]
public string Str1;

11、Class序列化

[Serializable]
public class TestClass
{public string Str = "这是一句话...";public bool IsOn;
}public class Test : MonoBehaviour
{public TestClass testClass;
}

12、[MenuItem("A/B")] 在菜单栏添加事件

（1）在顶部菜单栏添加事件

public class Test : MonoBehaviour
{[MenuItem("QAQ/QvQ")]public static void QvQ(){print("O-O");}
}

 

（2）在Project空白部分右键菜单栏添加事件

public class Test
{const string menuA = "Assets/QAQ/QvQ";const string menuB = "Assets/QAQ/Q_Q";const string menuC = "Assets/QAQ/QuQ";static bool isOn;[MenuItem(menuA, priority = 0, validate = false)]private static bool OvO(){bool value = !EditorPrefs.GetBool("HAHA", false);EditorPrefs.SetBool("HAHA", value);Menu.SetChecked(menuA, value);isOn = value;Debug.Log("OvO" + value);        return value;}[MenuItem(menuB, priority = 100)]private static void O_O(){if (isOn)Debug.Log("O_O");}[MenuItem(menuC)]private static void OuO(){if (!isOn)Debug.Log("OuO");}
}

  

 

二、继承Editor

1、[CustomEditor(typeof(Test))]

TestEditor类继承自Editor，[CustomEditor(typeof(Test))]特性指向Test类，可重写Test类的Inspector界面显示。

public class Test : MonoBehaviour
{public string Str;
}//Defines which object type the custom editor class can edit.
[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){//基于原本Test类的所有原本布局base.OnInspectorGUI();}
}

2、EditorGUILayout.PropertyField(); 

在不基于原InspectorGUI的情况下，显示原Class中的变量。

（1）PropertyField

public class Test : MonoBehaviour
{public string Str = "字符串";
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{SerializedProperty str;private void OnEnable(){str = serializedObject.FindProperty("Str");}public override void OnInspectorGUI(){//base.OnInspectorGUI();EditorGUILayout.PropertyField(str);//str.stringValue = "string...";//Apply property modifications.serializedObject.ApplyModifiedProperties();}
}

（2）Test t = (Test)target;

public class Test : MonoBehaviour
{public string Str = "字符串";
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){Test t = (Test)target;//以下写法一致//Test t = target as Test;t.Str = EditorGUILayout.TextField("_Str", t.Str);}
}

（3）示例1

public class Test : MonoBehaviour
{public bool IsOn = false;public string Str = "QAQ";public string Str1 = "T_T";
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{SerializedProperty str;SerializedProperty str1;private void OnEnable(){str = serializedObject.FindProperty("Str");str1 = serializedObject.FindProperty("Str1");}public override void OnInspectorGUI(){Test t = (Test)target;t.IsOn = EditorGUILayout.Toggle("_Toggle", t.IsOn);if (t.IsOn){EditorGUILayout.PropertyField(str);}else{EditorGUILayout.PropertyField(str1);}serializedObject.ApplyModifiedProperties();}
}

（4）示例2

public class Test : MonoBehaviour
{[Range(0,10)]public int Int;public enum TestType { A, B, C, }public TestType _TestType;//以下写法显示一样//[SerializeField]//TestType _TestType;
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{SerializedProperty _int;SerializedProperty _testType;private void OnEnable(){_int = serializedObject.FindProperty("Int");_testType = serializedObject.FindProperty("_TestType");}public override void OnInspectorGUI(){EditorGUILayout.PropertyField(_testType);EditorGUILayout.PropertyField(_int);switch (_int.intValue){case 1:_testType.intValue = (int)TestNew.ETestType.Type1;break;case 2:_testType.intValue = (int)TestNew.ETestType.Type2;break;default:_testType.intValue = (int)TestNew.ETestType.Type3;break;}serializedObject.ApplyModifiedProperties();}
}

3、各类Field（普通变量获取及定义）

public class Test : MonoBehaviour
{public string Str = "字符串";public string Password = "123456";public int Int = 1;public float Float = 1.1f;public double Double = 1.1;public long Long = 1;public bool Bool = true;public Gradient Gradient = new Gradient();public Color Color = Color.white;public AnimationCurve Curve = AnimationCurve.Linear(0, 0, 10, 10);public Vector2 V2 = new Vector2(1.1f, 1.1f);public Vector2Int V2Int = new Vector2Int(1, 1);public Vector3 V3 = new Vector3(1.1f, 1.1f, 1.1f);public Vector3Int V3Int = new Vector3Int(1, 1, 1);public Vector4 V4 = new Vector4(1.1f, 1.1f, 1.1f, 1.1f);public Rect Rect = new Rect(1.1f, 1.1f, 1.1f, 1.1f);public RectInt RectInt = new RectInt(1, 1, 1, 1);public Bounds Bounds = new Bounds(new Vector3(1.1f, 1.1f, 1.1f), new Vector3(1.1f, 1.1f, 1.1f));public BoundsInt BoundsInt = new BoundsInt(1, 1, 1, 1, 1, 1);public GameObject GameObj;public Camera Camera;public Toggle Toggle;
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){Test t = (Test)target;t.Str = EditorGUILayout.TextField("_Str", t.Str);//stringt.Password = EditorGUILayout.PasswordField("_Password", t.Password);//密码t.Int = EditorGUILayout.IntField("_Int", t.Int);//intt.Float = EditorGUILayout.FloatField("_Float", t.Float);//floatt.Double = EditorGUILayout.DoubleField("_Double", t.Double);//doublet.Long = EditorGUILayout.LongField("_Long", t.Long);//longt.Bool = EditorGUILayout.Toggle("_Toggle", t.Bool);//bool值，以toggle方式显示t.Gradient = EditorGUILayout.GradientField("_Gradient", t.Gradient);//颜色梯度t.Color = EditorGUILayout.ColorField("_Color", t.Color);//colort.Curve = EditorGUILayout.CurveField("_Curve", t.Curve);//curve曲线t.V2 = EditorGUILayout.Vector2Field("_V2", t.V2);//Vector2t.V2Int = EditorGUILayout.Vector2IntField("_V2Int", t.V2Int);//Vector2Intt.V3 = EditorGUILayout.Vector3Field("_V3", t.V3);//Vector3t.V4 = EditorGUILayout.Vector4Field("_V4", t.V4);//Vector4(X、Y、Z、W)t.Rect = EditorGUILayout.RectField("_Rect", t.Rect);//Rect(X、Y、W、H)t.RectInt = EditorGUILayout.RectIntField("_RectInt", t.RectInt);//RectInt(X、Y、W、H)t.Bounds = EditorGUILayout.BoundsField("_Bounds", t.Bounds);//Bounds，两个三维变量t.BoundsInt = EditorGUILayout.BoundsIntField("_BoundsInt", t.BoundsInt);//BoundsInt,两个三维整数变量GUILayout.Space(20f);//20f的空白GUILayout.Label("获取变量");t.GameObj = (GameObject)EditorGUILayout.ObjectField("_GameObj", t.GameObj, typeof(GameObject), true);t.Camera = (Camera)EditorGUILayout.ObjectField("_Camera", t.Camera, typeof(Camera), true);t.Toggle = (Toggle)EditorGUILayout.ObjectField("_Toggle", t.Toggle, typeof(Toggle), true);  }
}

4、Slider和下拉框

public class Test : MonoBehaviour
{public string SelectableLabel = "我可以被复制";public string Label = "哈哈哈";public string StrDelayedField = "int，按Enter键或将焦点从字段移开之前，不会返回新值";public float Slider = 1.1f;public int SliderInt = 1;public float SliderMin = 1.1f;public float SliderMax = 2.2f;public int PopupInt = 11;public int PopupStrIndex = 0;public int ArrayValue = 0;public string[] StrArray = new string[] { "AA", "BB", "CC", "DD", "EE" };public int[] IntArray = new int[] { 1, 2, 3, 4, 5 };public enum EnumType { A, B, C, D }public EnumType Enum0;public EnumType Enum1;public string Tag = "None";public int Layer = 0;
}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){Test t = (Test)target;EditorGUILayout.SelectableLabel(t.SelectableLabel);//可复制文字EditorGUILayout.LabelField("_Label", t.Label);//标签GUILayout.Space(10f);t.StrDelayedField = EditorGUILayout.DelayedTextField("_InputFieldEnter", t.StrDelayedField);EditorGUILayout.HelpBox("与EditorGUILayout.TextField类似，但在按Enter键或将焦点从字段移开之前，不会返回新值。", MessageType.Info);GUILayout.Space(10f);t.Slider = EditorGUILayout.Slider("_Slider", t.Slider, 0, 10);//滑动条t.SliderInt = EditorGUILayout.IntSlider("_IntSlider", t.SliderInt, 0, 10);//整数滑动条EditorGUILayout.MinMaxSlider("_MinMaxSlider", ref t.SliderMin, ref t.SliderMax, 1, 10);// 最小值、最大值滑动条(现在最小值、现在最大值、最小值、最大值)//下拉Int数选择框t.PopupInt = EditorGUILayout.IntPopup("_IntPopup", t.PopupInt, new[] { "a", "b" }, new[] { 11, 22 });//下拉string选择框t.PopupStrIndex = EditorGUILayout.Popup("_PopupStr", t.PopupStrIndex, new[] { "AA", "BB", "CC", "DD", "EE" });GUILayout.Space(10f);t.ArrayValue = EditorGUILayout.MaskField("_MaskField:", t.ArrayValue, t.StrArray);//下拉选择框，可多选EditorGUILayout.HelpBox("ArrayValue返回值为2的index次幂(0,-1,1,2,4,8,16...)(0、-1为nothing和everything选项)，若多选则为各返回值的和", MessageType.Info);GUILayout.Space(10f);//下拉选择框t.Enum0 = (Test.EnumType)EditorGUILayout.EnumFlagsField("_EnumType多选", t.Enum0);t.Enum1 = (Test.EnumType)EditorGUILayout.EnumPopup("_EnumType单选", t.Enum1);t.Tag = EditorGUILayout.TagField("_Tag", t.Tag);//Tag下拉框，可获取所有Tagt.Layer = EditorGUILayout.LayerField("_Layer", t.Layer);//Layer下拉框，可获取所有Layer }
}

5、区域、横纵向布局

public class Test : MonoBehaviour
{}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{bool isShowA;bool isShowB;float fspace = 0;Vector2 scrollPos;string scrollStr = "这是Scroll view区域";public override void OnInspectorGUI(){Test t = (Test)target;isShowA = EditorGUILayout.BeginToggleGroup("开启区域(BeginToggleGroup)", isShowA);GUILayout.Label("这是一片区域A");GUILayout.Label("----------------");EditorGUILayout.EndToggleGroup();EditorGUILayout.Space(20f);GUILayout.Label("不同平台(BeginBuildTargetSelectionGrouping)");BuildTargetGroup selectedBuildTargetGroup = EditorGUILayout.BeginBuildTargetSelectionGrouping();if (selectedBuildTargetGroup == BuildTargetGroup.Android){GUILayout.Label("安卓(BuildTargetGroup.Android)");}if (selectedBuildTargetGroup == BuildTargetGroup.WebGL){GUILayout.Label("WebGL(BuildTargetGroup.WebGL)");}if (selectedBuildTargetGroup == BuildTargetGroup.Standalone){GUILayout.Label("PC(BuildTargetGroup.Standalone)");}EditorGUILayout.EndBuildTargetSelectionGrouping();EditorGUILayout.Space(10f);GUILayout.Label("一个可变区域(BeginFadeGroup)");fspace = EditorGUILayout.Slider("可变范围", fspace, 0f, 2);if (EditorGUILayout.BeginFadeGroup(fspace)){GUILayout.Label("这是一片区域B");}EditorGUILayout.EndFadeGroup();if (isShowB = EditorGUILayout.BeginFoldoutHeaderGroup(isShowB, "一个可展开的区域(BeginFoldoutHeaderGroup)")){GUILayout.Label("这是一片区域C");}EditorGUILayout.EndFoldoutHeaderGroup();GUILayout.Space(10f);GUILayout.Label("一个Scroll区域(BeginScrollView)");scrollPos = EditorGUILayout.BeginScrollView(scrollPos, GUILayout.Width(150), GUILayout.Height(100));GUILayout.Label(scrollStr);EditorGUILayout.EndScrollView();//开始横向布局EditorGUILayout.BeginHorizontal();if (GUILayout.Button("添加一行文字", GUILayout.Width(100), GUILayout.Height(50))){scrollStr += " \n添加一行文字-------------";}//开始纵向布局EditorGUILayout.BeginVertical();if (GUILayout.Button("Clear")) {scrollStr = "";}if (GUILayout.Button("诗经")){scrollStr = "《蒹葭》\n 蒹葭苍苍,白露为霜。\n所谓伊人,在水一方。";}EditorGUILayout.EndVertical();EditorGUILayout.EndHorizontal();}
}

6、Foldout折叠区域

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{bool isShowA;bool isShowB;bool isShowC;public override void OnInspectorGUI(){if (isShowA = EditorGUILayout.BeginFoldoutHeaderGroup(isShowA, "折叠(点击范围为一整行)")){GUILayout.Box(new GUIContent("一个200x50的BOX"), new[] { GUILayout.Height(50), GUILayout.Width(200) });}EditorGUILayout.EndFoldoutHeaderGroup();isShowB = EditorGUILayout.Foldout(isShowB, "折叠(只可点小三角)");if (isShowB){GUILayout.BeginHorizontal("Box", GUILayout.Width(500));GUILayout.Label("水平布局", GUILayout.Width(100));GUILayout.Button("Button", GUILayout.Width(200));GUILayout.EndHorizontal();}isShowC = EditorGUILayout.InspectorTitlebar(isShowC, GameObject.Find("IsShowC"), true);if (isShowC){//用于解决EditorGUILayout和EditorGUI(或者GUI)混着用的情况//这样确保自动布局不会乱, 不会叠在一起Rect a = EditorGUILayout.GetControlRect();EditorGUI.LabelField(a, "这是区域C");EditorGUILayout.HelpBox("此处依据Hierarchy界面的GameObject物体的enabled状态来控制此处区域的开关", MessageType.Info);GUILayout.Label("------------");}}
}

7、HelpBox、Event、Button、Label、LinkButton超链接

（1）HelpBox提示框

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){EditorGUILayout.HelpBox("-------", MessageType.None);EditorGUILayout.HelpBox("-------", MessageType.Info);EditorGUILayout.HelpBox("-------", MessageType.Warning);EditorGUILayout.HelpBox("-------", MessageType.Error);}
}

（2）Event事件

}[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{SerializedProperty Action1;SerializedProperty Action2;private void OnEnable(){Action1 = serializedObject.FindProperty("Action1");Action2 = serializedObject.FindProperty("Action2");}public override void OnInspectorGUI(){EditorGUILayout.PropertyField(Action1);EditorGUILayout.PropertyField(Action2);serializedObject.ApplyModifiedProperties();}
}

（3）Button

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{GUIContent content;private void OnEnable(){content = EditorGUIUtility.TrTextContent("测试按钮", "这是一个测试按钮", "PlayButton");}public override void OnInspectorGU(){if (GUILayout.Button(content)){Debug.Log("点击了测试按钮");}serializedObject.ApplyModifiedProperties();//普通Buttonif (GUILayout.Button("Button", GUILayout.Width(100), GUILayout.Height(30))){//再次确认对话框DisplayDialogif (EditorUtility.DisplayDialog("再次确定", "是否确定", "确定", "取消")){Debug.Log("yes");}}}
}

（3）Label，显示图片

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){GUILayout.Label("图片");GUILayout.Label(Resources.Load<Texture2D>("Icon"), GUILayout.Width(100), GUILayout.Height(100));}
}

（5）LinkButton超链接

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){EditorGUILayout.LinkButton("");}
}

8、进度条、

（1）DisplayProgressBar

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{int range = 0;public override void OnInspectorGUI(){range = EditorGUILayout.IntSlider("完成度", range, 0, 100);if (range == 100 || range == 0){EditorUtility.ClearProgressBar();}else{EditorUtility.DisplayProgressBar("进度条", "当前进度", range / 100f);}}
}

（2）Knob

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{public override void OnInspectorGUI(){EditorGUILayout.Knob(new Vector2(50, 50), 40, 0, 100, "圆圈进度QvQ", Color.cyan, Color.blue, true);EditorGUILayout.Knob(new Vector2(50, 50), 60, 0, 100, "圆圈进度QwQ", Color.yellow, Color.red, true);}
}

9、工具栏Toolbar

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{int index = 0;public override void OnInspectorGUI(){index = GUILayout.Toolbar(index, new[] { "A", "B", "C"});switch (index){case 0:GUILayout.Label("这是A");break;case 1:GUILayout.Label("这是B");break;case 2:GUILayout.Label("这是C");break;}}

10、打开文件

无法打开文件，也无法保存文件，待研究。。。

[CustomEditor(typeof(Test))]
public class TestEditor : Editor
{string dir0, dir1, dir2, dir3, dir4, dir5;public override void OnInspectorGUI(){if (GUILayout.Button("打开文件位置")){dir0 = EditorUtility.OpenFilePanel("打开文件位置", dir0, ".txt");}if (GUILayout.Button("打开文件位置，筛选文件名称")){dir1 = EditorUtility.OpenFilePanelWithFilters("打开文件位置", dir1, new[] { "haha", "txt" });}if (GUILayout.Button("选择文件路径")){dir2 = EditorUtility.OpenFolderPanel("选择文件路径", dir2, "");}if (GUILayout.Button("保存文件")){dir3 = EditorUtility.SaveFilePanel("保存文件", dir3, "name", ".txt");}if (GUILayout.Button("在项目内保存文件")){dir4 = EditorUtility.SaveFilePanelInProject("在项目内保存文件", "name", "txt", "message");}if (GUILayout.Button("SaveFolderPanel")){dir5 = EditorUtility.SaveFolderPanel("保存文件", dir5, "name");}GUILayout.Space(20f);GUILayout.Label("-------------------------------------");GUILayout.Label("无法打开文件，也无法保存文件，待研究");}
}

三、继承PropertyDrawer

1、待研究，不太会...

[Serializable]
public class TestClass
{public float x;public float y;public float z;public float w;
}public class Test : MonoBehaviour
{public TestClass testClass;
}[CustomPropertyDrawer(typeof(TestClass))]
public class TestClassEditor : PropertyDrawer
{public override void OnGUI(Rect position, SerializedProperty property, GUIContent label){Rect positionZ;Rect positionW;EditorGUI.BeginProperty(position, label, property);//显示字段标签，返回标签占用后剩余的区域if (position.width >= 200){EditorGUIUtility.labelWidth = position.width / 3;}else{EditorGUIUtility.labelWidth = 50;}position = EditorGUI.PrefixLabel(position, label);//区域宽度设置为一半if (position.width >= 200){position.width = position.width / 3;}else if (position.width < 100){position.width = position.width / 2;}else{position.width = 70;}//调整标签Label宽度为当前的1/2EditorGUIUtility.labelWidth = 15;EditorGUI.PropertyField(position, property.FindPropertyRelative("x"));positionZ = new Rect(position.x, position.y + 20, position.width, position.height);EditorGUI.PropertyField(positionZ, property.FindPropertyRelative("z"));//y属性右移position.x += position.width + 5;EditorGUI.PropertyField(position, property.FindPropertyRelative("y"));positionW = new Rect(position.x, position.y + 20, position.width, position.height);EditorGUI.PropertyField(positionW, property.FindPropertyRelative("w"));EditorGUI.EndProperty();}
}
