本章节实现了死亡后重新启动游戏，并且加入了游戏管理器

加入了重新开始游戏的按钮

GameManager.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;//2024.11.28 17:04
public class GameManager : MonoBehaviour
{public static GameManager instance;//单例模式,全局变量private void Awake(){if (instance != null)Destroy(instance.gameObject);elseinstance = this;}public void RestartScene(){Scene scene = SceneManager.GetActiveScene();SceneManager.LoadScene(scene.name);}
}

UI.cs

修改了结束动画之后的协程，加入了重启

using System.Collections;
using UnityEngine;
using UnityEngine.UI;public class UI : MonoBehaviour
{[Header("End screens")][SerializeField] private UI_FadeScreen fadeScreen;[SerializeField] private GameObject endText;[SerializeField] private GameObject restartButton;[Space][SerializeField] private GameObject characterUI;[SerializeField] private GameObject skillTreeUI;[SerializeField] private GameObject craftUI;[SerializeField] private GameObject optionsUI;[SerializeField] private GameObject inGameUI;//物品提示框和状态提示框public UI_SkillToolTip skillToolTip;public UI_ItemTooltip itemToolTip;public UI_StatToolTip statToolTip;public UI_CraftWindow craftWindow;private void Awake(){SwitchTo(skillTreeUI);//2024年11月22日，P138 Skill Tree Hot Fix，启动时默认显示技能树界面}void Start(){SwitchTo(inGameUI);itemToolTip.gameObject.SetActive(false);//戏启动时隐藏物品提示框和状态提示框statToolTip.gameObject.SetActive(false);}void Update(){if (Input.GetKeyDown(KeyCode.C))SwitchWithKeyTo(characterUI);if (Input.GetKeyDown(KeyCode.B))SwitchWithKeyTo(craftUI);if (Input.GetKeyDown(KeyCode.K))SwitchWithKeyTo(skillTreeUI);if (Input.GetKeyDown(KeyCode.O))SwitchWithKeyTo(optionsUI);}public void SwitchTo(GameObject _menu)// 该方法用于切换到指定的UI界面{for (int i = 0; i < transform.childCount; i++)//遍历当前UI对象的所有子物体{bool fadeScreen = transform.GetChild(i).GetComponent<UI_FadeScreen>() != null;//检查UI界面是否有FadeScreensif (fadeScreen==false)transform.GetChild(i).gameObject.SetActive(false);//遍历并隐藏所有子元素,确保了在显示新的UI界面时，所有其他的UI界面都会被隐藏}if (_menu != null)//传入的菜单不为空{_menu.SetActive(true);//显示}}public void SwitchWithKeyTo(GameObject _menu)//处理切换UI的逻辑{if (_menu != null && _menu.activeSelf)// UI界面已经显示，隐藏, 如果目标UI界面未显示，调用 SwitchTo 显示。{_menu.SetActive(false);CheckForInGameUI();return;}SwitchTo(_menu);}private void CheckForInGameUI()//关闭其他UI都会回到InGameUI{for (int i = 0; i < transform.childCount; i++){if (transform.GetChild(i).gameObject.activeSelf)//检查当前 UI 对象的第 i 个子对象是否处于激活状态。return;}SwitchTo(inGameUI);}public void SwitchOnEndScreen(){fadeScreen.FadeOut();StartCoroutine(EndScreenCorutione());}IEnumerator EndScreenCorutione(){yield return new WaitForSeconds(1);endText.SetActive(true);yield return new WaitForSeconds(1.7f);restartButton.SetActive(true);}public void RestartGameButton() => GameManager.instance.RestartScene();
