字典在Inspector的显示

方法一：实现ISerializationCallbackReceiver接口

《unity3D游戏开发第二版》记录
在编辑面板中可以利用序列化监听接口特性对字典进行序列化。
主要继承ISerializationCallbackReceiver接口 实现OnAfterDeserialize() OnBeforeSerialize() 的方法进行监听序列化和反序列化之前的事件。

例子：
配置的ScriptableObject脚本：

[CreateAssetMenu(fileName = "FileName2PathConfig", menuName = "xasset/Custom/FileName2PathConfig")]public class FileName2PathConfig : ScriptableObject{public SerializationDic<string, string> fileDictionary;}// Dictionary<TKey, TValue> 可序列化字典[Serializable]public class SerializationDic<TKey, TValue> :ISerializationCallbackReceiver{[SerializeField]List<TKey> keys;[SerializeField]List<TValue> values;Dictionary<TKey, TValue> target;public Dictionary<TKey, TValue> ToDictionary() { return target; }public SerializationDic(Dictionary<TKey, TValue> target){this.target = target;}public void OnBeforeSerialize(){keys = new List<TKey>(target.Keys);values = new List<TValue>(target.Values);}public void OnAfterDeserialize(){var count = Math.Min(keys.Count, values.Count);target = new Dictionary<TKey, TValue>(count);for (var i = 0; i < count; ++i){target.Add(keys[i], values[i]);}}}

控制Inspector面板显示的脚本：

[CustomEditor(typeof(SerializationDic<string,string>))]public class SerializationDicEditor : Editor{public override void OnInspectorGUI(){//更新数据serializedObject.Update();SerializedProperty propertyKey=serializedObject.FindProperty("keys");SerializedProperty propertyValue=serializedObject.FindProperty("values");int size=propertyKey.arraySize;GUILayout.BeginVertical();for(int i=0;i<size;i++){GUILayout.BeginHorizontal();SerializedProperty key=propertyKey.GetArrayElementAtIndex(i);SerializedProperty value=propertyValue.GetArrayElementAtIndex(i);key.stringValue=EditorGUILayout.TextField("key",key.stringValue);value.stringValue=EditorGUILayout.TextField("value",value.stringValue);GUILayout.EndHorizontal();}GUILayout.EndVertical();//保存数据serializedObject.ApplyModifiedProperties();}}

效果

方法二 使用插件Odin Inspector 官网

代码：

[CreateAssetMenu(fileName = "FileName2PathConfig", menuName = "xasset/Custom/FileName2PathConfig")]public class FileName2PathConfig : SerializedScriptableObject{[DictionaryDrawerSettings(KeyLabel = "资源名字", ValueLabel = "资源路径")]public Dictionary<string, string> fileDictionary;}

效果：
