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;
    }
