4.按钮功能
5.题目对错判断

四、后言

一、前言 【Unity3D实战之答题系统的实现】这是本专栏系列的第一篇，答题系统的开发。
这个答题系统，可以从文本文档中提取题目和分数，然后绑定到UI上，在答题的过程中，自动判断分数，自动判断正确率。
目的是实现一个可快速导入到项目中使用的小模块。
二、效果图及工程下载

题目文档密码:1234
源工程

三、实现
1.界面搭建
首先，新建工程，然后摆UI，如下图所示：

2.读取文档
题目存放在txt文档中，首先，我们看一下结构：

每一行都是一道题目，然后题号、题目、选项、得分，都是用冒号进行分割的。
下一步就需要用脚本进行读取文档了。
新建脚本Answer.cs：编写代码：
读取文档：

using System.Collections.Generic; using UnityEngine; public class Answer : MonoBehaviour{//读取文档string[][] ArrayX; string[] lineArray; private int topicMax = 0; //最大题数private List isAnserList = new List(); //存放是否答过题的状态void Start(){TextCsv(); }/*****************读取txt数据******************/void TextCsv(){//读取csv二进制文件TextAsset binAsset = Resources.Load("YW", typeof(TextAsset)) as TextAsset; //读取每一行的内容lineArray = binAsset.text.Split('\r'); //创建二维数组ArrayX = new string[lineArray.Length][]; //把csv中的数据储存在二维数组中for (int i = 0; i < lineArray.Length; i++){ArrayX[i] = lineArray[i].Split(':'); }//查看保存的题目数据for (int i = 0; i < ArrayX.Length; i++){for (int j = 0; j < ArrayX[i].Length; j++){Debug.Log(ArrayX[i][j]); }}//设置题目状态topicMax = lineArray.Length; for (int x = 0; x < topicMax + 1; x++){isAnserList.Add(false); }}}

可以看到，所有的题目数据都读取出来了：

3.加载题目

using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class Answer : MonoBehaviour{//读取文档string[][] ArrayX; //题目数据string[] lineArray; //读取到题目数据private int topicMax = 0; //最大题数private List isAnserList = new List(); //存放是否答过题的状态//加载题目public GameObject tipsbtn; //提示按钮public Text tipsText; //提示信息public List toggleList; //答题Togglepublic Text indexText; //当前第几题public Text TM_Text; //当前题目public List DA_TextList; //选项private int topicIndex = 0; //第几题void Start(){TextCsv(); LoadAnswer(); }/*****************读取txt数据******************/void TextCsv(){//读取csv二进制文件TextAsset binAsset = Resources.Load("YW", typeof(TextAsset)) as TextAsset; //读取每一行的内容lineArray = binAsset.text.Split('\r'); //创建二维数组ArrayX = new string[lineArray.Length][]; //把csv中的数据储存在二维数组中for (int i = 0; i < lineArray.Length; i++){ArrayX[i] = lineArray[i].Split(':'); }//设置题目状态topicMax = lineArray.Length; for (int x = 0; x < topicMax + 1; x++){isAnserList.Add(false); }}/*****************加载题目******************/void LoadAnswer(){tipsbtn.SetActive(false); tipsText.text = ""; for (int x = 0; x < 4; x++){toggleList[x].isOn = false; }indexText.text = "第" + (topicIndex + 1) + "题："; //第几题TM_Text.text = ArrayX[topicIndex][1]; //题目int idx = ArrayX[topicIndex].Length - 3; //有几个选项for (int x = 0; x < idx; x++){DA_TextList[x].text = ArrayX[topicIndex][x + 2]; //选项}}}

题目正常加载：

4.按钮功能

/*****************按钮功能******************/void Select_Answer(int index){switch (index){case 0://提示int idx = ArrayX[topicIndex].Length - 1; int n = int.Parse(ArrayX[topicIndex][idx]); string nM = ""; switch (n){case 1:nM = "A"; break; case 2:nM = "B"; break; case 3:nM = "C"; break; case 4:nM = "D"; break; }tipsText.text = "" +"正确答案是："+ nM + ""; break; case 1://上一题if (topicIndex > 0){topicIndex--; LoadAnswer(); }else{tipsText.text = "" + "前面已经没有题目了！" + ""; }break; case 2://下一题if (topicIndex < topicMax-1){topicIndex++; LoadAnswer(); }else{tipsText.text = "" + "哎呀！已经是最后一题了。" + ""; }break; case 3://跳转int x = int.Parse(jumpInput.text) - 1; if (x >= 0 && x < topicMax){topicIndex = x; jumpInput.text = ""; LoadAnswer(); }else{tipsText.text = "" + "不在范围内！" + ""; }break; }}

5.题目对错判断

/*****************题目对错判断******************/void AnswerRightRrongJudgment(bool check,int index){if (check){//判断题目对错bool isRight; int idx = ArrayX[topicIndex].Length - 1; int n = int.Parse(ArrayX[topicIndex][idx]) - 1; if (n == index){tipsText.text = "" + "恭喜你，答对了！" + ""; isRight = true; tipsbtn.SetActive(true); }else{tipsText.text = "" + "对不起，答错了！" + ""; isRight = false; tipsbtn.SetActive(true); }//正确率计算if (isAnserList[topicIndex]){tipsText.text = "" + "这道题已答过！" + ""; }else{anserint++; if (isRight){isRightNum++; }isAnserList[topicIndex] = true; TextAccuracy.text = "正确率：" + ((float)isRightNum / anserint * 100).ToString("f2") + "%"; }//禁用掉选项for (int i = 0; i < toggleList.Count; i++){toggleList[i].interactable = false; }}}

将按钮对象拖进卡槽中，运行程序即可：

完整代码如下：

using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class Answer : MonoBehaviour{//读取文档string[][] ArrayX; //题目数据string[] lineArray; //读取到题目数据private int topicMax = 0; //最大题数private List isAnserList = new List(); //存放是否答过题的状态//加载题目public GameObject tipsbtn; //提示按钮public Text tipsText; //提示信息public List toggleList; //答题Togglepublic Text indexText; //当前第几题public Text TM_Text; //当前题目public List DA_TextList; //选项private int topicIndex = 0; //第几题//按钮功能及提示信息public Button BtnBack; //上一题public Button BtnNext; //下一题public Button BtnTip; //消息提醒public Button BtnJump; //跳转题目public InputField jumpInput; //跳转题目public Text TextAccuracy; //正确率private int anserint = 0; //已经答过几题private int isRightNum = 0; //正确题数void Awake(){TextCsv(); LoadAnswer(); }void Start(){toggleList[0].onValueChanged.AddListener((isOn) => AnswerRightRrongJudgment(isOn,0)); toggleList[1].onValueChanged.AddListener((isOn) => AnswerRightRrongJudgment(isOn,1)); toggleList[2].onValueChanged.AddListener((isOn) => AnswerRightRrongJudgment(isOn,2)); toggleList[3].onValueChanged.AddListener((isOn) => AnswerRightRrongJudgment(isOn,3)); BtnTip.onClick.AddListener(() => Select_Answer(0)); BtnBack.onClick.AddListener(() => Select_Answer(1)); BtnNext.onClick.AddListener(() => Select_Answer(2)); BtnJump.onClick.AddListener(() => Select_Answer(3)); }/*****************读取txt数据******************/void TextCsv(){//读取csv二进制文件TextAsset binAsset = Resources.Load("YW", typeof(TextAsset)) as TextAsset; //读取每一行的内容lineArray = binAsset.text.Split('\r'); //创建二维数组ArrayX = new string[lineArray.Length][]; //把csv中的数据储存在二维数组中for (int i = 0; i < lineArray.Length; i++){ArrayX[i] = lineArray[i].Split(':'); }//设置题目状态topicMax = lineArray.Length; for (int x = 0; x < topicMax + 1; x++){isAnserList.Add(false); }}/*****************加载题目******************/void LoadAnswer(){for (int i = 0; i < toggleList.Count; i++){toggleList[i].isOn = false; }for (int i = 0; i < toggleList.Count; i++){toggleList[i].interactable = true; }tipsbtn.SetActive(false); tipsText.text = ""; indexText.text = "第" + (topicIndex + 1) + "题："; //第几题TM_Text.text = ArrayX[topicIndex][1]; //题目int idx = ArrayX[topicIndex].Length - 3; //有几个选项for (int x = 0; x < idx; x++){DA_TextList[x].text = ArrayX[topicIndex][x + 2]; //选项}}/*****************按钮功能******************/void Select_Answer(int index){switch (index){case 0://提示int idx = ArrayX[topicIndex].Length - 1; int n = int.Parse(ArrayX[topicIndex][idx]); string nM = ""; switch (n){case 1:nM = "A"; break; case 2:nM = "B"; break; case 3:nM = "C"; break; case 4:nM = "D"; break; }tipsText.text = "" +"正确答案是："+ nM + ""; break; case 1://上一题if (topicIndex > 0){topicIndex--; LoadAnswer(); }else{tipsText.text = "" + "前面已经没有题目了！" + ""; }break; case 2://下一题if (topicIndex < topicMax-1){topicIndex++; LoadAnswer(); }else{tipsText.text = "" + "哎呀！已经是最后一题了。" + ""; }break; case 3://跳转int x = int.Parse(jumpInput.text) - 1; if (x >= 0 && x < topicMax){topicIndex = x; jumpInput.text = ""; LoadAnswer(); }else{tipsText.text = "" + "不在范围内！" + ""; }break; }}/*****************题目对错判断******************/void AnswerRightRrongJudgment(bool check,int index){if (check){//判断题目对错bool isRight; int idx = ArrayX[topicIndex].Length - 1; int n = int.Parse(ArrayX[topicIndex][idx]) - 1; if (n == index){tipsText.text = "" + "恭喜你，答对了！" + ""; isRight = true; tipsbtn.SetActive(true); }else{tipsText.text = "" + "对不起，答错了！" + ""; isRight = false; tipsbtn.SetActive(true); }//正确率计算if (isAnserList[topicIndex]){tipsText.text = "" + "这道题已答过！" + ""; }else{anserint++; if (isRight){isRightNum++; }isAnserList[topicIndex] = true; TextAccuracy.text = "正确率：" + ((float)isRightNum / anserint * 100).ToString("f2") + "%"; }//禁用掉选项for (int i = 0; i < toggleList.Count; i++){toggleList[i].interactable = false; }}}}

四、后言整体来看，只使用了一个场景，一个脚本，就完成了答题系统。
步骤如下：
1、读取文档
2、解析文档保存数据
3、根据数据加载题目
4、上一题下一题，选项选择，跳转，按钮的功能实现
代码还是延期了一贯的简洁风格，希望你可以在这篇文章学到东西。
