雖然mono是支持unicode的。可以在枚舉里寫中文，但是我還是覺得寫英文好一些。可是在編輯器上策劃是希望看到的是中文的，還有就是枚舉的展示排序功能，策劃在編輯的時候為了方便希望把常用的枚舉排上前面。

把如下代碼放到你的工程里就可以直接用了。

C#

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161

使用是這樣的，第二個參數就是排序。接收int的不固定參數。

C#

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

using UnityEngine; using System.Collections; public class NewBehaviourScript : MonoBehaviour { ????[EnumLabel("我是的類型",10,1,5,2)] ????public NewType newType = NewType.One; } public enum NewType : byte { ????[EnumLabel("我是1")] ????One = 10, ????[EnumLabel("我是2")] ????Two = 1, ????[EnumLabel("我是3")] ????Three = 5, ????[EnumLabel("我是4")] ????Four = 2 }

OK 中文與排序都OK了。

但是，有時候我們做編輯器的時候是自己調用OnInspectorGUI來繪制面板的。而且我的枚舉對象可能會在另外一個子對象里，或者在子對象里的一個List<T>里面的子對象里。

比如這樣， class.data.newType 就是這個類對象的結構，你可以按照你自己類的結構去拼這個字符串。

C#

1 2 3 4 5 6 7 8 9 10

????????public override void OnInspectorGU() ????????{ ????????????NewType oldType = (NewType)EnumLabel.GetEnum(typeof(NewType),serializedObject,"class/data/newType"); ????????????NewType newType = (NewType)EnumLabel.DrawEnum(typeof(NewType),serializedObject,"class/data/newType"); ????????????if(oldType != newType) ????????????{ ????????????????//類型發生改變 ????????????} ????????}

還有一種特殊的就是可能枚舉在list<T>里，這樣在繪制的時候是需要遍歷的。

C#

1 2 3 4 5 6 7 8 9 10

?????? public override void OnInspectorGU() ????????{ ????????????SerializedProperty property = EnumLabel.GetPropety(serializedObject,"class/datas"); ????????????for(int i =0; i<??count; i++) ????????????{ ????????????????SerializedProperty eProperty = property.GetArrayElementAtIndex(i); ????????????????NewType newType = (NewType)EnumLabel.DrawEnum(typeof(NewType),serializedObject ????????????????????????????,eProperty.FindPropertyRelative("newType")); ????????????} ????????}

OK大功告成。
