二、新增收集事件
1、新增物体
(1) 新增物体：UI-Image。Questions。设置它的Rect Transform。
(2) 新增文本：ItemsText, TipText（可设置有透明度的黑色背景）
2、新建CollectedItems.cs
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;public class CollectedItems : MonoBehaviour
{public QuestionCollision QuestionCollision;//public GameObject Questions;public TextMeshProUGUI ItemsText, TipText;static int nucleus=0, mitochondria = 0, GolgiApparatus = 0, endoplasmicReticulum = 0, ribosome = 0;void Start(){if (ItemsText == null || TipText == null){Debug.LogError("Questions或ItemsText 或 TipText 未被正确分配!");}}private void OnTriggerEnter(Collider other){if (other.CompareTag("Player")){RandomEvent();}}public void RandomEvent(){int numericValue = Random.Range(0, 100);if (numericValue < 5 && nucleus==0){nucleus = 1;TipText.text = "你发现了细胞核！";}else if(numericValue < 26){mitochondria++;TipText.text = "你得到了线粒体！";}else if (numericValue < 41){endoplasmicReticulum++;TipText.text = "你得到了内质网*1！";}else if (numericValue < 56){GolgiApparatus++;TipText.text = "你得到了高尔基体*1！";}else if (numericValue < 76){ribosome++;TipText.text = "你得到了核糖体*1！";}else if (numericValue < 86){QuestionCollision.ShowQuestions(true);//Questions.SetActive(true);}else{TipText.text = "你什么都没有发现……";}ItemsUpdate();}void ItemsUpdate(){ItemsText.text = "当前持有：细胞核" + nucleus + "；线粒体" + mitochondria + "；高尔基体" + GolgiApparatus + "；内质网" + endoplasmicReticulum + "；核糖体" + ribosome;}
}using System;
using System.Collections;
using System.Collections.Generic;
using TMPro;
using Unity.Mathematics;
using UnityEngine;
using UnityEngine.UI;
using static UnityEngine.Rendering.DebugUI;public class Observer : MonoBehaviour
{public Exercises exercises;public Transform player;public GameObject Questions;public TextMeshProUGUI ItemsText, TipText;static int nucleus=0, mitochondria = 0, GolgiApparatus = 0, endoplasmicReticulum = 0, ribosome = 0;bool canTriggerEffect = true;void OnTriggerEnter(Collider other){if (other.CompareTag("Player")) // 玩家的标签为 "Player" {exercises.ShowQuestion(0);RandomEvent(); }}public void QuitBtn() {GetComponent<UnityEngine.UI.Button>().gameObject.SetActive(false);Questions.SetActive(false);}void ItemsUpdate(){ItemsText.text ="当前持有：细胞核" + nucleus + "；线粒体" + mitochondria + "；高尔基体" + GolgiApparatus + "；内质网" + endoplasmicReticulum + "；核糖体" + ribosome;}void Start(){if (ItemsText == null || TipText == null){Debug.LogError("ItemsText 或 TipText 未被正确分配!");}}void RandomEvent(){if (canTriggerEffect){// 触发效果代码int numericValue = UnityEngine.Random.Range(0, 100);if (numericValue < 5 && nucleus == 0)//获取的随机数范围在0~4{nucleus = 1;TipText.text = "你发现了细胞核！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 21){mitochondria++;TipText.text = "你得到了线粒体！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 41){endoplasmicReticulum++;TipText.text = "你得到了内质网*1！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 61){GolgiApparatus++;TipText.text = "你得到了高尔基体*1！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 81){ribosome++;TipText.text = "你得到了核糖体*1！"; StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 96){Questions.SetActive(true);}else{TipText.text = "你什么都没有发现……";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}//gameEnding.CaughtPlayer ();ItemsUpdate();canTriggerEffect = false; // 触发效果，将canTriggerEffect设置为falseStartCoroutine(CooldownRoutine()); // 启动冷却时间协程}}IEnumerator CooldownRoutine(){yield return new WaitForSeconds(60f); // 等待1分钟canTriggerEffect = true; // 冷却结束，可以再次触发效果}IEnumerator ClearTextRoutine(float delay){yield return new WaitForSeconds(delay);TipText.text = "";}
}3、更改enemy设置
(1) 复制 PointOfView预制体，得到PointOfView(1)，更名为CollectedItems
(2) 移除CollectedItems上的Observer.cs，添加CollectedItems.cs
(3) 删除Hierarchy面板上的除Ghost (3)以外的敌人的PointOfView。添加CollectedItems预制体并赋值
三、编辑答题面板预制体
1、设置面板
(1) UI-Image，命名为Questions。
(2) 选中导入的图片，然后在Inspector面板中将Texture Type设置为Sprite (2D and UI)
(3) 更改Questions的Image，Transform
(4) 添加按钮，QuitBtn（以隐藏答题面板）
2、添加test
(1) 添加文本。TitleText
(2) 添加按钮。OptionBtnA，按钮下文本的名字OptionTextA，更改文字字体，复制这个按钮得到四个选项按钮
(3) 将Questions制成预制体
(4) 制作题目
3、建立题库——简单题库
A. 创建ChoiceQuestion.cs（不用挂载的脚本）可以与其他脚本放在一起
定义问题类（包含一个问题（question字段）、四个选项（options数组）和正确答案的索引（correctOptionIndex字段））
using System.Collections;
using System.Collections.Generic;
using UnityEngine;[System.Serializable]
public class Question
{public string question; // 问题文本public string[] options = new string[4]; // 选项数组，假设每个问题都有4个选项public int correctOptionIndex; // 正确答案的索引（0表示A，1表示B，依此类推）// 构造函数（可选），用于初始化问题public Question(string q, string[] opts, int correctIndex){question = q;options = opts;correctOptionIndex = correctIndex;}// 检查答案是否正确public bool CheckAnswer(int playerChoice){return playerChoice == correctOptionIndex;}
}B. 在一个空物体上添加Exercises.cs，控制显示题目和选项、正误判断、答题后禁用按钮
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;public class Exercises : MonoBehaviour
{public Database_01 Database_01;//题库脚本public TextMeshProUGUI questionText;public Button[] optionButtons;private int currentQuestionIndex = 0; // 初始化当前问题索引为0public void ShowQuestion(int index){if (index >= 0 && index < Database_01.questionsDatabase.Count)//如果index在questionsDatabase列表的有效范围内{// 显示题目(从列表中取出索引为index的问题，并将其文本内容显示在questionText的文本组件上）questionText.text = Database_01.questionsDatabase[index].question;// 显示选项（将Database_01中当前问题的选项文本显示在optionButtons数组或列表中的相应UI元素上）for (int i = 0; i < Database_01.questionsDatabase[index].options.Length; i++){optionButtons[i].GetComponentInChildren<TextMeshProUGUI>().text = Database_01.questionsDatabase[index].options[i];}}}// 选项按钮的点击事件public void OnOptionButtonClicked(int buttonIndex){foreach (var button in optionButtons){button.interactable = false; // 设置为false以禁用按钮}// currentQuestionIndex：当前显示的问题的索引// 检查用户选择的答案是否正确bool isCorrect = Database_01.questionsDatabase[currentQuestionIndex].CheckAnswer(buttonIndex);// 根据检查结果执行相应的操作，比如更新UI、显示消息等if (isCorrect){Debug.Log("回答正确！");currentQuestionIndex++; // 更新当前问题索引}else{Debug.Log("回答错误！");}}
}C.给空物体添加Database_01.cs，以建立题库
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Database_01 : MonoBehaviour
{public List<Question> questionsDatabase = new List<Question>(); // 选择题数据库void Start(){// 初始化选择题数据库InitializeQuestions();}void InitializeQuestions(){//添加一个问题到数据库questionsDatabase.Add(new Question("…………是？",new string[] { "A. ……", "B. ……", "C. ……", "D. ……" },0 // 假设"选项A"是正确答案，所以索引是0));//添加一个问题到数据库questionsDatabase.Add(new Question("…………",new string[] { "A. 复杂性", "B. 多样性", "C. 统一性", "D. 稳定性" },2 // 假设"选项C"是正确答案，所以索引是2));}
}4、建立题库——导入txt文本的方式
(1) 加载文本
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using TMPro;
using UnityEngine;public class QuizManager : MonoBehaviour
{private Question currentQuestion;//存储当前展示的题目private List<Question> questionList;public TextMeshProUGUI questionTextComponent; // 用于显示题干的Text组件public TextMeshProUGUI optionATextComponent; // 用于显示选项A的Text组件public TextMeshProUGUI optionBTextComponent; // 用于显示选项B的Text组件public TextMeshProUGUI optionCTextComponent; // 用于显示选项C的Text组件public TextMeshProUGUI optionDTextComponent; // 用于显示选项D的Text组件void Start(){questionList = new List<Question>();LoadQuestionsFromTxt("QuestionBank.txt");GetRandomQuestion();}//加载文本文件void LoadQuestionsFromTxt(string filename){// 组合文件的完整路径。Application.streamingAssetsPath是Unity的一个属性，// 指向StreamingAssets文件夹的路径string filePath = Path.Combine(Application.streamingAssetsPath, filename);// 检查文件是否存在if (File.Exists(filePath)){// 使用File.OpenText来打开文件，并创建一个StreamReader来读取内容using (StreamReader reader = File.OpenText(filePath)){// 声明一个字符串变量line，用于存储从文件中读取的每一行内容string line;// 逐行读取文件内容，直到读取到文件末尾while ((line = reader.ReadLine()) != null){// 使用 | 分隔每一行的内容string[] data = line.Split('|');// 检查是否至少有6个由竖线分隔的值（问题、四个选项和答案）if (data.Length < 6){Debug.LogError("Invalid line format in question file: " + line);continue; // 跳过这一行，继续读取下一行}// 从分割后的数组中提取问题、选项和答案string question = data[0];string optionA = "A.

}
// 定义一个名为Question的类，用于存储问题及其相关信息
[Serializable]
public class Question
{public string QuestionText;public string OptionAText;public string OptionBText;public string OptionCText;public string OptionDText;public string Answer; // 注意这里不需要ToUpper()，除非您有特定的需求public Question(string question, string optionA, string optionB, string optionC, string optionD, string answer){QuestionText = question;OptionAText = optionA;OptionBText = optionB;OptionCText = optionC;OptionDText = optionD;Answer = answer;}

}// 定义一个名为Question的类，用于存储问题及其相关信息
[Serializable]
public class Question
{public string QuestionText;public string OptionAText;public string OptionBText;public string OptionCText;public string OptionDText;public string Answer; // 注意这里不需要ToUpper()，除非您有特定的需求public Question(string question, string optionA, string optionB, string optionC, string optionD, string answer){QuestionText = question;OptionAText = optionA;OptionBText = optionB;OptionCText = optionC;OptionDText = optionD;Answer = answer;}
}(1)
(2) QuestionBank.txt文件位于Unity项目的StreamingAssets文件夹中，并且格式正确（即每行都有六个由 | 分隔的值）答案用ABCD表示
(3)
(4)
4、设置调用test
(1) 给JohnLemon添加PlayerQuest.cs
5、判断正误
6、生命值脚本
using UnityEngine;public class PlayerHealth : MonoBehaviour
{public int maxLives = 3;private int currentLives;private void Start(){currentLives = maxLives;}public void AddLife(){if (currentLives < maxLives){currentLives++;}}public void LoseLife(){if (currentLives > 0){currentLives--;}else{Debug.Log("角色死亡！退出游戏");}}
}
7、问题面板显示和隐藏脚本
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;public class QuestionCollision : MonoBehaviour
{public GameObject questionPanel;//问题面板public Button QuitBtn;public TextMeshProUGUI questionText;//问题文本public Button[] optionBtns;public PlayerHealth playerHealth;public void ShowQuestions(bool isQuestionActivated){if (isQuestionActivated){questionPanel.SetActive(true);}else{questionPanel.SetActive(false);}foreach (Button button in optionBtns){button.onClick.AddListener(()=> CheckAnswer(button));}}public void OnClickQuitBtn(){questionPanel.SetActive(false);}void Start(){questionPanel.SetActive(false);}private void CheckAnswer(Button button){if (button.CompareTag("CorrectAnswer")){playerHealth.AddLife();}questionPanel.SetActive(false);}
} public List<Transform> bodyList = new List<Transform>();public GameObject bodyPrefab;public Sprite[] bodySprites = new Sprite[2];//数组中只含有2张图片private Transform canvas;private void Awake(){canvas = GameObject.Find("Canvas").transform;//找到Canvas的Transform}void BodyCreate(){//如果bodyList的元素数量是偶数，Index将被赋值为0。如果bodyList的元素数量是奇数，Index将被赋值为1int Index = (bodyList.Count % 2 == 0) ? 0 : 1;//bodyList.Count：列表中的元素数量（生成几种物体）//bodyList.Count % 2：元素数量除以2，的余数//bodyList.Count % 2 == 0：检查余数是否是0（是0，说明元素数量是偶数）//? 0 : 1：如果元素数量是偶数（余数是0）则整个表达式的值是0。否则是1GameObject body = Instantiate(bodyPrefab,new Vector3(2000,2000,0),Quaternion.identity);//生成预制体在看不到的位置body.GetComponent<UnityImage>().sprite = bodySprites[Index];//从bodySprites数组中获取位于Index位置的图片body.transform.SetParent(canvas, false);//使Canvas成为body的父物体，而不使用它的世界坐标bodyList.Add(body.transform);}ItemsBackground，ItemsText，TipText
九、暂存
1、隐藏按钮
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class ButtonHideObjectController : MonoBehaviour
{public GameObject objectToHide; // 在Inspector中设置这个引用void Start(){// 获取Button组件Button button = GetComponent<Button>();if (button != null){// 添加点击事件监听器button.onClick.AddListener(HideObject);Debug.Log(button.interactable);}}// 点击按钮时调用的方法public void HideObject(){if (objectToHide != null){objectToHide.SetActive(false); // 隐藏物体}}
}2、含有构造函数的问题组成设置
using System.Collections;
using System.Collections.Generic;
using UnityEngine;[System.Serializable]
public class Question
{public string question; // 问题文本public string[] options = new string[4]; // 选项数组，假设每个问题都有4个选项public int correctOptionIndex; // 正确答案的索引（0表示A，1表示B，依此类推）// 构造函数（可选），用于初始化问题public Question(string q, string[] opts, int correctIndex){question = q;options = opts;correctOptionIndex = correctIndex;}// 检查答案是否正确public bool CheckAnswer(int playerChoice){return playerChoice == correctOptionIndex;}
}3、题库脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Database_01 : MonoBehaviour
{public List<Question> questionsDatabase = new List<Question>(); // 选择题数据库void Start(){// 初始化选择题数据库InitializeQuestions();}void InitializeQuestions(){//添加一个问题到数据库questionsDatabase.Add(new Question("生命系统最基本的结构层次是？",new string[] { "A. 细胞", "B. 组织", "C. 器官", "D. 系统" },0 // 假设"选项A"是正确答案，所以索引是0));//添加一个问题到数据库questionsDatabase.Add(new Question("细胞学说揭示了动物和植物的",new string[] { "A. 复杂性", "B. 多样性", "C. 统一性", "D. 稳定性" },2 // 假设"选项C"是正确答案，所以索引是2));}
}4、显示题目并判断对错
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UI;public class Exercises : MonoBehaviour
{public Database_01 Database_01;//题库脚本public TextMeshProUGUI questionText;public Button[] optionButtons;private int currentQuestionIndex = 0; // 初始化当前问题索引为0public void ShowQuestion(int index){if (index >= 0 && index < Database_01.questionsDatabase.Count)//如果index在questionsDatabase列表的有效范围内{// 显示题目(从列表中取出索引为index的问题，并将其文本内容显示在questionText的文本组件上）questionText.text = Database_01.questionsDatabase[index].question;// 显示选项（将Database_01中当前问题的选项文本显示在optionButtons数组或列表中的相应UI元素上）for (int i = 0; i < Database_01.questionsDatabase[index].options.Length; i++){optionButtons[i].GetComponentInChildren<TextMeshProUGUI>().text = Database_01.questionsDatabase[index].options[i];}}}// 选项按钮的点击事件public void OnOptionButtonClicked(int buttonIndex){foreach (var button in optionButtons){button.interactable = false; // 设置为false以禁用按钮}// currentQuestionIndex：当前显示的问题的索引// 检查用户选择的答案是否正确bool isCorrect = Database_01.questionsDatabase[currentQuestionIndex].CheckAnswer(buttonIndex);// 根据检查结果执行相应的操作，比如更新UI、显示消息等if (isCorrect){Debug.Log("回答正确！");currentQuestionIndex++; // 更新当前问题索引}else{Debug.Log("回答错误！");}}
}5、退出
using TMPro;
using UnityEngine;
using UnityEngine.SceneManagement;public class GameEnding : MonoBehaviour
{public float fadeDuration = 1f;public float displayImageDuration = 1f;public GameObject player;public CanvasGroup exitBackgroundImageCanvasGroup;public AudioSource exitAudio;public CanvasGroup caughtBackgroundImageCanvasGroup;public AudioSource caughtAudio;bool m_IsPlayerAtExit;bool m_IsPlayerCaught;float m_Timer;bool m_HasAudioPlayed;void OnTriggerEnter (Collider other){if (other.gameObject == player){m_IsPlayerAtExit = true;}}public void CaughtPlayer (){m_IsPlayerCaught = true;}void Update (){if (m_IsPlayerAtExit){EndLevel (exitBackgroundImageCanvasGroup, false, exitAudio);}else if (m_IsPlayerCaught){EndLevel (caughtBackgroundImageCanvasGroup, true, caughtAudio);}}void EndLevel (CanvasGroup imageCanvasGroup, bool doRestart, AudioSource audioSource){if (!m_HasAudioPlayed){audioSource.Play();m_HasAudioPlayed = true;}m_Timer += Time.deltaTime;imageCanvasGroup.alpha = m_Timer / fadeDuration;if (m_Timer > fadeDuration + displayImageDuration){if (doRestart){SceneManager.LoadScene (0);}else{Application.Quit ();}}}
}6、获取物体
using System;
using System.Collections;
using System.Collections.Generic;
using TMPro;
using Unity.Mathematics;
using UnityEngine;
using UnityEngine.UI;
using static UnityEngine.Rendering.DebugUI;public class Observer : MonoBehaviour
{public Exercises exercises;public Transform player;public GameObject Questions;public TextMeshProUGUI ItemsText, TipText;static int nucleus=0, mitochondria = 0, GolgiApparatus = 0, endoplasmicReticulum = 0, ribosome = 0;bool canTriggerEffect = true;void OnTriggerEnter(Collider other){if (other.CompareTag("Player")) // 玩家的标签为 "Player" {exercises.ShowQuestion(0);RandomEvent(); }}public void QuitBtn() {GetComponent<UnityEngine.UI.Button>().gameObject.SetActive(false);Questions.SetActive(false);}void ItemsUpdate(){ItemsText.text ="当前持有：细胞核" + nucleus + "；线粒体" + mitochondria + "；高尔基体" + GolgiApparatus + "；内质网" + endoplasmicReticulum + "；核糖体" + ribosome;}void Start(){if (ItemsText == null || TipText == null){Debug.LogError("ItemsText 或 TipText 未被正确分配!");}}void RandomEvent(){if (canTriggerEffect){// 触发效果代码int numericValue = UnityEngine.Random.Range(0, 100);if (numericValue < 5 && nucleus == 0)//获取的随机数范围在0~4{nucleus = 1;TipText.text = "你发现了细胞核！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 21){mitochondria++;TipText.text = "你得到了线粒体！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 41){endoplasmicReticulum++;TipText.text = "你得到了内质网*1！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 61){GolgiApparatus++;TipText.text = "你得到了高尔基体*1！";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 81){ribosome++;TipText.text = "你得到了核糖体*1！"; StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}else if (numericValue < 96){Questions.SetActive(true);}else{TipText.text = "你什么都没有发现……";StartCoroutine(ClearTextRoutine(2f));print("随机数" + numericValue);}//gameEnding.CaughtPlayer ();ItemsUpdate();canTriggerEffect = false; // 触发效果，将canTriggerEffect设置为falseStartCoroutine(CooldownRoutine()); // 启动冷却时间协程}}IEnumerator CooldownRoutine(){yield return new WaitForSeconds(60f); // 等待1分钟canTriggerEffect = true; // 冷却结束，可以再次触发效果}IEnumerator ClearTextRoutine(float delay){yield return new WaitForSeconds(delay);TipText.text = "";}
