unity 如何将字典显示在Inspector面板上

主要通过ISerializationCallbackReceiver接口来实现, 将所有的Value值存入List显示即可. 这里在value里存了一个Key 也可以将Key和value分别保存

    public interface RecordValue<T>
    {
        public T Key { get; }
    }
  
    [Serializable]
    public class RecordDictionary<TKey, TValue> : ISerializationCallbackReceiver, IEnumerable<KeyValuePair<TKey, TValue>> 
        where TValue : RecordValue<TKey> 
    {
        [Tooltip("组")]
        public TValue Peek => Group.Count > 0 ? Group[0] : default(TValue);
        //缓存数据,通过key加快访问查询
        [SerializeField]
        Dictionary<TKey, TValue> table = new (); 
        public ICollection<TValue> Values => table.Values;
        public TValue this[TKey index]
        {
            get => table[index];
            set
            {
                if (table.ContainsKey(index))
                    table[index] = value;
                else
                    table.Add(index, value);
            }
        }
        public int Count => table.Count;
        [SerializeField]
        protected List<TValue> Group = new();

        public void Remove(TKey _index)
        {
            if (table.ContainsKey(_index))
            {
                table.Remove(_index);
            }
        }
        public bool Contains(TKey _index)
        {
            return table.ContainsKey(_index);
        }
        public void Clear()
        {
            table.Clear();
        }

        public IEnumerator<KeyValuePair<TKey, TValue>> GetEnumerator()
        {
            return (IEnumerator<KeyValuePair<TKey, TValue>>)table.GetEnumerator();
        }

        IEnumerator IEnumerable.GetEnumerator()
        {
            return table.GetEnumerator();
        }

        public void OnBeforeSerialize()
        {
            Group.Clear();
            foreach (var kv in table)
            {
                Group.Add(kv.Value);
            }
        }

        public void OnAfterDeserialize()
        {
            table.Clear();
            foreach (TValue value in Group)
            {
                if (table.ContainsKey(value.Key))
                {
                    Debug.LogWarning("无法添加字段");
                    if(value.Key is string s)
                    {
                        //table.Add((TKey)s.FixedRename(), value);
                    }
                    continue;
                }
                table.Add(value.Key, value);
            }
        }
    }
