[游戏开发]关于Unity中字典在Inspector的显示

字典在Inspector的显示

《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。

public class SerializeTest :MonoBehaviour,ISerializationCallbackReceiver
{
    [SerializeField]
    private List<Sprite> mValues=new List<Sprite>();
    [SerializeField]
    private List<string> mKeys=new List<string>();
    public Dictionary<string,Sprite> mSpriteDic=new Dictionary<string, Sprite>(5);
    /// <summary>
   /// 监听发序列化之前的事件
   /// </summary>
    public void OnAfterDeserialize()
    {
        mSpriteDic.Clear();
        if(mKeys.Count!=mValues.Count) Debug.Log("键和值不对应");
        else
        {
            //进行添加到字典中
            for(int i=0;i<mValues.Count;++i)
            {
                mSpriteDic.Add(mKeys[i],mValues[i]);
            }
        }
    }

   /// <summary>
   /// 监听序列化之前的事件
   /// </summary>
    public void OnBeforeSerialize()
    {
        mKeys.Clear();
        mValues.Clear();
        foreach(var pair in mSpriteDic)
        {
             mKeys.Add(pair.Key);
             mValues.Add(pair.Value);
        }
    }
}

#if UNITY_EDITOR
[CustomEditor(typeof(SerializeTest))]
public class ScriptInspector:Editor
{
      public override void OnInspectorGUI()
    {
        //更新数据
        serializedObject.Update();
        SerializedProperty propertyKey=serializedObject.FindProperty("mKeys");
        SerializedProperty propertyValue=serializedObject.FindProperty("mValues");
        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.objectReferenceValue=EditorGUILayout.ObjectField("value",
            value.objectReferenceValue,typeof(Sprite),false);
            GUILayout.EndHorizontal();
        }
        GUILayout.EndVertical();
        GUILayout.BeginHorizontal();
        if(GUILayout.Button("+"))
        {
            (target as SerializeTest).mSpriteDic[size.ToString()]=null;
        }
        GUILayout.EndHorizontal();
        //保存数据
        serializedObject.ApplyModifiedProperties();
    }
