贪吃蛇
本篇文章是先不看老师教程的情况下，自己独立来完成的，顺便记录一下实现的过程。
项目展示
方向控制：WSAD
确定键：J
需求分析（UML类图）
UML类图是老师提供的，因为以我现在的能力还画不出逻辑这么清晰的UML类图！
补充知识点：
检测键盘是否激活
Console.KeyAvailable == true;
注意使用后会使程序变慢，具体为什么我还不得而知，后面慢慢的积累学习我想我会弄明白的。
开始前：
按照UML类图逐个去写逐个去实现（但是有些模块我没有用上）
主要精力是放在了功能实现上
下面是我实现的过程
一、万事开头难--游戏类
（我先确定了开始着手的地方--游戏类，因为它是所有类和方法的汇聚地）
cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//游戏类
namespace 自个先写CSharp核心小项目_贪吃蛇_
{
enum E_Scene
{
BeginID,
GamingID,
FinishID,
}
class Game
{
public static int x;
public static int y;
public static E_Scene scene = new E_Scene();
Begin begin = new Begin();
Finish finish = new Finish();
public Game()
{
x = 100;
y = 30;
scene = E_Scene.BeginID;
}
//初始化控制台
public void Consoles()
{
//隐藏光标
Console.CursorVisible = false;
//设置舞台大小
Console.SetWindowSize(x, y);
Console.SetBufferSize(x, y);
}
//游戏主循环
public void MajorCycle()
{
while (true)
{
//思考一下，为什么把开始场景和结束场景的类申明放在外面，而游戏场景的类申明放循环里面
//因为开始结束场景是一成不变的，只需申明一次就够用了
//而游戏场景进入一次就会执行出结果出来，每次结果都将不一样，所以每次都得重新申明
switch (scene)
{
case E_Scene.BeginID:
Console.Clear();
begin.newers();
break;
case E_Scene.GamingID:
Console.Clear();
GameScene gameScene = new GameScene();
gameScene.newers();
break;
case E_Scene.FinishID:
Console.Clear();
finish.newers();
break;
default:
break;
}
}
}
//场景切换
public void SceneMove()
{
}
}
}二、游戏帧更新接口
1.更新接口
2.开始和结束场景基类
开始场景类
cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//开始场景
namespace 自个先写CSharp核心小项目_贪吃蛇_
{
class Begin : BeginAndFinish
{
public Begin()
{
str = "贪吃蛇";
str1 = "开始游戏";
str2 = "结束游戏";
}
//重写更新方法
public override void newers()
{
Console.SetCursorPosition(48, 10);
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine(str);
Console.SetCursorPosition(47, 13);
Console.ForegroundColor = key == 1 ? ConsoleColor.Red : ConsoleColor.White;
Console.WriteLine(str1);
Console.SetCursorPosition(47, 15);
Console.ForegroundColor = key == 2 ? ConsoleColor.Red : ConsoleColor.White;
Console.WriteLine(str2);
char c = Console.ReadKey(true).KeyChar;
switch (c)
{
case 'W':
case 'w':
key = 1;
break;
case 'S':
case 's':
key = 2;
break;
case 'J':
case 'j':
if (key == 2)
{
//关闭控制台
Environment.Exit(0);
}
Game.scene = (E_Scene)key;
break;
default:
break;
}
}
}
}结束场景类
cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//结束场景
namespace 自个先写CSharp核心小项目_贪吃蛇_
{
class Finish : BeginAndFinish
{
string str0;
public static int num;
public Finish()
{
key = 0;
str = "游戏结束";
str0 = "本次游戏的长度为:";
str1 = "回到开始界面";
str2 = "结束游戏";
}
//重写更新方法
public override void newers()
{
Console.SetCursorPosition(47, 10);
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine(str);
Console.SetCursorPosition(42, 12);
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine(str0 + num);
Console.SetCursorPosition(45, 15);
Console.ForegroundColor = key == 0 ? ConsoleColor.Red : ConsoleColor.White;
Console.WriteLine(str1);
Console.SetCursorPosition(47, 17);
Console.ForegroundColor = key == 2 ? ConsoleColor.Red : ConsoleColor.White;
Console.WriteLine(str2);
char c = Console.ReadKey(true).KeyChar;
switch (c)
{
case 'W':
case 'w':
key = 0;
break;
case 'S':
case 's':
key = 2;
break;
case 'J':
case 'j':
if (key == 2)
{
//关闭控制台
Environment.Exit(0);
}
Game.scene = (E_Scene)key;
break;
default:
break;
}
}
}
}（这里面其实可以把这些方法提取到开始和结束场景基类里面的，但我懒，没有去整！！！）
3.游戏场景类
（第二个大类，游戏里的墙壁、食物、蛇、各种方法等等都汇聚在这个类中）
三、游戏场景中的各类
1.绘制接口
2.游戏对象类
（讲真的这个类没怎么用上，具体怎么用我还得看看老师是怎么用的）
3.位置结构体
（这个是完全没有用上！！）
4.地图墙壁类
5.食物类
6.蛇类--（最复杂的类）
蛇身体类--没用上
蛇类
cs
using System;
using System.Collections.Generic;

//打印出长度

//蛇绘制

{
//打印长度
Console.SetCursorPosition(2, 1);
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine(longs + bodyNum);
Finish.num = bodyNum;
//蛇头的绘制
Console.SetCursorPosition(x, y);
Console.ForegroundColor = ConsoleColor.Yellow;
Console.WriteLine(snakeHead);
//蛇身的绘制
for (int i = 0; i < bodyNum; i++)

C#核心实践项目（自个先写）--贪吃蛇
全部代码文件：看资源
说一下：CSDN下载个资源还要VIP，真服了！
如果需要源码的可以私信滴滴我，无偿！
但是代码有些拙劣，不要建议。
总结一下下
代码有点屎山，but跑起来就好！！！
还是知识点运用的不够，很多没用上。
