43. 实现休息房间的逻辑

本节目标

实现休息房间可以回一次血，实现宝箱房间可以获得卡牌

实现办法

休息房间回血

添加一个 RestRoomPanel，给它挂上 UI 和脚本

代码实现如下

using System;
using UnityEngine;
using UnityEngine.UIElements;

public class RestRoomPanel : MonoBehaviour
{
    private VisualElement rootElement;
    private Button restButton;
    private Button backToMapButton;

    public Effect restEffect;

    public ObjectEventSO loadMapEvent;

    private CharacterBase player;

    private void OnEnable()
    {
        rootElement = GetComponent<UIDocument>().rootVisualElement;
        restButton = rootElement.Q<Button>("RestButton");
        backToMapButton = rootElement.Q<Button>("BackToMapButton");

        player = FindAnyObjectByType<Player>(FindObjectsInactive.Include);

        restButton.clicked += OnRestButtonClicked;
        backToMapButton.clicked += OnBackToMapButtonClicked;
    }

    private void OnBackToMapButtonClicked()
    {
        loadMapEvent.RaiseEvent(null, this);
    }

    private void OnRestButtonClicked()
    {
        restEffect.Execute(player, null);
        restButton.SetEnabled(false);
    }
}

当点击休息一下之后，会执行 restEffect，然后禁用休息按钮

当点击返回地图之后，会广播loadMapEvent事件

其中 restEffect 是一个给自己回 20 点血的卡牌效果
