序列化显示问题

[amerkiousy (c1oudust)]

最近把做的一个小游戏迁移到了3.0，inspector面板上自定义属性的序列化显示出现了问题。
自定义一个item类

自定义数组

在inspector面板里显示是这样的

自定义属性里的内容完全没显示上去，请问该怎么解决，还是我的写法有问题？

https://docs.cocos.com/creator/3.0/manual/zh/scripting/ccclass.html item只是保存数据就没必要继承component了吧

[amerkiousy (c1oudust)]

然后就变成了这样

[22647814 (Ailzac)]

import { _decorator, CCInteger, SpriteFrame } from "cc";

const { ccclass, property } = _decorator;

@ccclass("Item")

export class Item {

  @property({

    displayName: "ID",

    type: CCInteger,

    serializable: true,

  } as any)

  public id: number = 0;

  @property({

    displayName: "Image",

    type: SpriteFrame,

    serializable: true,

  } as any)

  public img: SpriteFrame | null = null;

}

import { _decorator, Component, Node } from "cc";

import { Item } from "./Item";

const { ccclass, property } = _decorator;

@ccclass("ItemManager")

export class ItemManager extends Component {

  @property([Item])

  public items: Item[] = [];

}
