Unity3D答题系统
恬静的小魔龙 人气:0一、前言
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
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<bool> isAnserList = new List<bool>();//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<bool> isAnserList = new List<bool>();//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<Toggle> toggleList;//答题Toggle public Text indexText;//当前第几题 public Text TM_Text;//当前题目 public List<Text> 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 = "<color=#FFAB08FF>" +"正确答案是:"+ nM + "</color>"; break; case 1://上一题 if (topicIndex > 0) { topicIndex--; LoadAnswer(); } else { tipsText.text = "<color=#27FF02FF>" + "前面已经没有题目了!" + "</color>"; } break; case 2://下一题 if (topicIndex < topicMax-1) { topicIndex++; LoadAnswer(); } else { tipsText.text = "<color=#27FF02FF>" + "哎呀!已经是最后一题了。" + "</color>"; } 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 = "<color=#27FF02FF>" + "不在范围内!" + "</color>"; } 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 = "<color=#27FF02FF>" + "恭喜你,答对了!" + "</color>"; isRight = true; tipsbtn.SetActive(true); } else { tipsText.text = "<color=#FF0020FF>" + "对不起,答错了!" + "</color>"; isRight = false; tipsbtn.SetActive(true); } //正确率计算 if (isAnserList[topicIndex]) { tipsText.text = "<color=#FF0020FF>" + "这道题已答过!" + "</color>"; } 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<bool> isAnserList = new List<bool>();//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<Toggle> toggleList;//答题Toggle public Text indexText;//当前第几题 public Text TM_Text;//当前题目 public List<Text> 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 = "<color=#FFAB08FF>" +"正确答案是:"+ nM + "</color>"; break; case 1://上一题 if (topicIndex > 0) { topicIndex--; LoadAnswer(); } else { tipsText.text = "<color=#27FF02FF>" + "前面已经没有题目了!" + "</color>"; } break; case 2://下一题 if (topicIndex < topicMax-1) { topicIndex++; LoadAnswer(); } else { tipsText.text = "<color=#27FF02FF>" + "哎呀!已经是最后一题了。" + "</color>"; } 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 = "<color=#27FF02FF>" + "不在范围内!" + "</color>"; } 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 = "<color=#27FF02FF>" + "恭喜你,答对了!" + "</color>"; isRight = true; tipsbtn.SetActive(true); } else { tipsText.text = "<color=#FF0020FF>" + "对不起,答错了!" + "</color>"; isRight = false; tipsbtn.SetActive(true); } //正确率计算 if (isAnserList[topicIndex]) { tipsText.text = "<color=#FF0020FF>" + "这道题已答过!" + "</color>"; } 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。
