本文使用winform实现简单的石头剪刀布的游戏，主要实现，电脑随机出拳，玩家手动点击出拳；实现简易背景图片3秒切换；简易统计信息。
1、效果图
2.实现代码
新建一个windows窗体程序,用数字1代表石头，用数字2代表剪刀，用数字3代表布，结果取玩家和电脑出拳之差，有三种结果
- 玩家赢: -1，2
- 平手: 0
- 玩家输: 其它值
新建3个类：
1）Computer.cs 电脑随机出拳
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; namespace 石头剪刀布
{
class Computer
{ public string Fist
{
get;
set;
} public int ShowFist()
{
Random rnd = new Random();
int fist = rnd.Next(, );
switch (fist)
{
case : Fist = "石头"; break;
case : Fist = "剪刀"; break;
case : Fist = "布"; break;
}
return fist;
} }
}
2）、Judge.cs 裁判类 判断输赢
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; namespace 石头剪刀布
{ class Judge
{ public enum RESULT
{
玩家赢,
电脑赢,
平手
} public static RESULT WhoWin(int playerNum, int computerNum)
{
int result = playerNum - computerNum;
if (result == - || result == )
{
return RESULT.玩家赢;
}
else if (result == )
{
return RESULT.平手; }
else
{
return RESULT.电脑赢;
} } }
}
3）、Player.cs 玩家，出拳
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; namespace 石头剪刀布
{
class Player
{
public static int ShowFist(string fist)
{
switch (fist)
{
case "石头": return ;
case "剪刀": return ;
case "布": return ;
default: return ;
}
} }
}
界面后台实现代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms; namespace 石头剪刀布
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
/// <summary>
/// 点击石头按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnStone_Click(object sender, EventArgs e)
{
String fist = "石头";
Game(fist);
}
/// <summary>
/// 点击剪刀按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnScissors_Click(object sender, EventArgs e)
{
String fist = "剪刀";
Game(fist);
}
/// <summary>
/// 点击布按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnCloth_Click(object sender, EventArgs e)
{
String fist = "布";
Game(fist); } //背景图片轮播
String[] paths = Directory.GetFiles(@"C:\work\stone");//此目录里面必须有图片，否则会报错
private void timer1_Tick(object sender, EventArgs e)
{
this.BackgroundImage = Image.FromFile(paths[new Random().Next(, paths.Length)]); }
static int playerWinTimes = ;//玩家赢的次数
static int gameTimes = ;//总共次数
static int tieTimes = ;//平手次数 /// <summary>
/// 通用方法
/// </summary>
/// <param name="fist"></param>
private void Game(String fist)
{
gameTimes++;
lbPlayer.Text = fist;
int playerNum = Player.ShowFist(fist);
Computer cpu = new Computer();
int cpuNum = cpu.ShowFist();
lbComputer.Text = cpu.Fist;
Judge.RESULT result = Judge.WhoWin(playerNum, cpuNum);
lbJudge.Text = result.ToString();
lbStatistics.Text = "统计信息：\n\n1.您赢了" + playerWinTimes + "场比赛!\n\n" + "2.平手了" + tieTimes + "次; \n\n" + "3.输掉了" + (gameTimes - playerWinTimes - tieTimes) + "场比赛; \n\n" + "4.共进行了" + gameTimes + "场比赛!\n\n"; if (result == Judge.RESULT.玩家赢)
{
playerWinTimes++;
MessageBox.Show("恭喜，您已经赢了" + playerWinTimes + "场比赛！" + " 共进行了" + gameTimes + "场比赛！");
}
else if (result == Judge.RESULT.平手)
{
tieTimes++;
} } }
}
实现游戏的难点在于要想到将石头剪刀布用数字来替换,如果逻辑通了实现起来并不难。
