在Game场景中，每个UI的UpdateFun需要通过消息系统来更新。

首先先在Scripts——Module中新建Message文件夹

MessageSystem

using System.Collections.Generic;

public interface IMessageSystem
{
    void AddListener(int key, IReceiver receiver);
    void RemoveListener(int key, IReceiver receiver);
    void DispatchMsg(int key, params object[] args);

    void AddListener(string key, IReceiver receiver);
    void RemoveListener(string key, IReceiver receiver);
    void DispatchMsg(string key, params object[] args);
}

public class MessageSystem : IMessageSystem
{
    private readonly Dictionary<int, HashSet<IReceiver>> _intReceivers = new();
    private readonly Dictionary<string, HashSet<IReceiver>> _stringReceivers = new();
    public void AddListener(int key, IReceiver receiver)
    {
        if (!_intReceivers.ContainsKey(key))
        {
            _intReceivers[key] = new HashSet<IReceiver>();
        }
        _intReceivers[key].Add(receiver);
    }
    public void RemoveListener(int key, IReceiver receiver)
    {
        if (_intReceivers.ContainsKey(key))
        {
            _intReceivers[key].Remove(receiver);
        }
    }
    public void DispatchMsg(int key,params object[] args)
    {
        foreach (var receiver in _intReceivers[key])
        {
            receiver.ReceiveMessage(args);
        }
    }

    public void AddListener(string key, IReceiver receiver)
    {
        if (!_stringReceivers.ContainsKey(key))
        {
            _stringReceivers[key] = new HashSet<IReceiver>();
        }
        _stringReceivers[key].Add(receiver);
    }

    public void RemoveListener(string key, IReceiver receiver)
    {
        if (_stringReceivers.ContainsKey(key))
        {
            _stringReceivers[key].Remove(receiver);
        }
    }

    public void DispatchMsg(string key, params object[] args)
    {
        foreach (var receiver in _stringReceivers[key])
        {
            receiver.ReceiveMessage(args);
        }
    }
}

使用int作为key，性能相对更好。

使用string作为key备用，后面输入模块会用到。

IReceiver

public interface IReceiver
{
    void ReceiveMessage(params object[] args);
}

MsgEvent

在Const文件夹内新建MsgEvent，在里面定义各种Event常量，使用int作为key。

public class MsgEvent
{
    public const int EVENT_HP = 0;
    public const int EVENT_SCORE = 1;
}

MessageMgr

在Manager文件夹中新建MessageMgr

public class MessageMgr : NormalSingleton<MessageMgr>, IMessageSystem
{
    private MessageSystem _messageSystem;
    public MessageMgr()
    {
        _messageSystem = new MessageSystem();
    }
    public void AddListener(int key, IReceiver receiver)
    {
        _messageSystem.AddListener(key, receiver);
    }

    public void AddListener(string key, IReceiver receiver)
    {
        _messageSystem.AddListener(key, receiver);
    }

    public void DispatchMsg(int key, params object[] args)
    {
        _messageSystem.DispatchMsg(key, args);
    }

    public void DispatchMsg(string key, params object[] args)
    {
        _messageSystem.DispatchMsg(key, args);
    }

    public void RemoveListener(int key, IReceiver receiver)
    {
        _messageSystem.RemoveListener(key, receiver);
    }

    public void RemoveListener(string key, IReceiver receiver)
    {
        _messageSystem.RemoveListener(key, receiver);
    }
}

GameUIView

修改GameUIView，添加修改分数和星星的逻辑

[BindPrefab(Pathes.GAMEUI_VIEW,Consts.BIND_PREFAB_PRIORITY_VIEW)]
public class GameUIView : ViewBase, IReceiver
{
    public void ReceiveMessage(params object[] args)
    {
        UpdateScore();
        UpdateStars();
    }

    protected override void InitChild()
    {
        UIUtil.Get("Life").AddCo<Life>();
        UpdateScore();
        UpdateStars();
    }
    public override void Show()
    {
        base.Show();
        MessageMgr.Instance.AddListener(MsgEvent.EVENT_SCORE, this);
    }
    public override void Hide()
    {
        base.Hide();
        MessageMgr.Instance.RemoveListener(MsgEvent.EVENT_SCORE, this);
    }
    private void UpdateScore()
    {
        UIUtil.Get("Score").SetText(GameModel.Instance.Score);
    }
    private void UpdateStars()
    {
        UIUtil.Get("Star/Value").SetText(GameModel.Instance.Stars);
    }
}
