第一款自己的VS控制台小游戏

版权声明：虽然都是基础，但都是开源的，哈哈。 https://blog.csdn.net/qq_41490433/article/details/84796474

当你用c++控制台一直练习  cout<<"hellow world"  写各种循环  写数组、链表、容器。

当你已经厌烦 看到你想要的内容输出在控制台上的那份成就感 ，你是否想写点不一样的东西。

在这里我就记录下写的第一个游戏——贪吃蛇。

                                                                                                                                                                                                --导读

  写一个完整的程序准备是非常重要的。

  首先我们要了解的游戏的本质：死循环（死循环的方法只有你点了退出游戏或者关闭电源）

  然后就是框架，打好一个框架对后续的编程有很大的影响，不然新手总会出现写了这行又停下来想半天下一行怎么写。

  最后就是动手了，动手是最快的学习编程的方法，如果你有想法，那就赶紧下载软件，然后开始自己的第一个项目。

  说了半天什么是死循环呢，死循环又怎么写呢。

  我们可以先想想一个最简单的游戏，就是我说1，你说2，然后我说3，直到谁说不下去或者不想说了。是不是很幼稚，但是用代码又是如何实现呢？

int main()
{
	while (true)
	{
        //玩家1输入i
        //玩家2输入i+1
    }
}    

伪代码。。。

切入正题

贪吃蛇嘛。先事先构思一下思路

1.画一个地图

2.然后画出蛇

3.让蛇移动

4.产生食物

5.蛇吃食物

6.撞自己或撞墙

1.画地图

首先需要画一个地图，先画一个矩形吧，这里没用到绘画技术，而是用到最简单的形式输出

int arrMap[20][40] = 
{
	1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,2,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
	1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,
};

没错，就是定义一个数组，但是如果只是输出01的话感觉不是很美观

这个时候我们就需要来遍历这个数组，当数组为0的时候就输出空地，为1就输出墙

void DrawALL()
{
	for (int i = 0; i < 20; i++)
	{
		for (int j = 0; j < 40; j++) 
		{
			if (1 == arrMap[i][j])
			{
				cout << "※";
			}
			else
			{
				cout << "  ";
			}
		}cout << endl;
	}
}

2.画蛇

其实贪吃蛇有很多种方法，但最终版的就是用链表去画蛇。不懂链表的可以翻翻我之前的笔记，有C++里的链表

首先定义一个蛇的结构体，就是蛇的蛇头和每一节身体。

//蛇结构体定义
struct Snake
{
    //初始化
	Snake()
	{
		iRow = 0;
		iCol = 0;
		pNext = nullptr;
		iRowBk = 0;
		iColBk = 0;
	}
    //行列坐标
	int iRow;
	int iCol;
    //行列坐标备份
	int iRowBk;
	int iColBk;
    //指向下一节身体
	Snake* pNext;
    //备份，每次走了一步后备份，先封装，后续使用
	void BackUp()
	{
		iRowBk = iRow;
		iColBk = iCol;
	}
};

结构体定义好了，接下来就是先画一个蛇头了

	//蛇头的初始化
	Snake* pSnakeHead = new Snake;
	pSnakeHead->iRow = 15;
	pSnakeHead->iCol = 15;
    //蛇身
	Snake* pSnakeBody = new Snake;
    //链接蛇头与蛇身
	pSnakeHead->pNext = pSnakeBody;

接着就是让他渲染出来了

在之前的渲染函数改进一下

for (int i = 0; i < 20; i++)
	{
		for (int j = 0; j < 40; j++)
		{
			if (1 == arrMap[i][j])
			{
				cout << "※";
			}
            //画蛇
			else if (DrawSnake(pSnakeHead, i, j))
			{
				cout << "◎";
			}
			else
			{
				cout << "  ";
			}
		}cout << endl;
	}

到这里就画出一条蛇来了

3.让蛇移动

说到移动，就先要想到移动的4个方向，因为用到链表，所以只要控制蛇头移动，其他的自动继承上一节点的坐标就能达到移动的效果了，这里用枚举来定义4个方向。枚举之前也有所说明

//蛇头的方向定义
enum
{
	//上，下，左，右
	E_SNAKE_UP,
	E_SNAKE_DOWN,
	E_SNAKE_LEFT,
	E_SNAKE_RIGHT
};

接下来就是让蛇根据方向移动，将下面的代码写在一开始写的while（true） 大循环里就可以了，当然这里只是没考虑速度的

    //最开始已蛇头为当前节点
    Snake* CurNode =pSnakeHead;
    //备份
	CurNode->BackUp();
     //让下一节点继承当前节点的坐标
	while (nullptr != CurNode&&nullptr!=CurNode->pNext)
	{
		CurNode->pNext->BackUp();
		CurNode->pNext->iRow = CurNode->iRowBk;
		CurNode->pNext->iCol = CurNode->iColBk;
		CurNode = CurNode->pNext;
	}
    //移动头节点，direction为方向，在初始的时候根据自己喜好定义好
	switch (direction)
	{
	case E_SNAKE_UP:
		pSnakeHead->iRow -= 1;
		break;
	case E_SNAKE_DOWN:
		pSnakeHead->iRow += 1;
		break;
	case E_SNAKE_LEFT:
		pSnakeHead->iCol -= 1;
		break;
	case E_SNAKE_RIGHT:
		pSnakeHead->iCol += 1;
		break;
	default:
		break;
	}

这时候你会发现你的蛇只能快速往你定义的方向一直走，然后消失在屏幕

那么这时候我们需要手动去改变蛇的方向了，键盘监听事件，这是游戏人机交互必须的方法。先加头文件

#include<cstdlib>
//用到的一起写上吧，不懂的自己搜一下
#include "stdafx.h"
#include<Windows.h>
#include<iostream>
#include<cstdlib>
#include <conio.h>
#include<vector>
using namespace std;

// x 为方向，这里封装了一个函数
int SetDirection(int x)
{
	char ch;
	if (_kbhit())
	{
		ch = _getch();
		switch (ch)
		{
		case ('w'):
            如果按了上，方向变为上
            x = E_SNAKE_UP;
			break;
		case 's':
            x = E_SNAKE_DOWN;
			break;
		case 'a':
            x = E_SNAKE_LEFT;
			break;
		case 'd':
            x = E_SNAKE_RIGHT;
			break;
		case ' ':
			system("pause");
			break;
		default:
			break;
		}
	}
	return x;
}

当然，在while（true)循环里也要调用这个函数，以此来实时获取改变的方向

direction = SetDirection(direction);

做到这里就能上下左右的移动了。

4.产生食物

蛇出来了，也能移动了，那就需要产生食物了，这时候就需要函数的重要性了。

敲代码的时候我们经常希望  随便什么时候只要简单地敲一句代码就能实现很复杂的功能。比如我写个 makeFood() 就能随机产生一个食物。但是万事开头难，想要这么简单就需要在一开始的时候就把该做的做了，专业名字 叫  定义。。。

首先要在main函数之前声明，并且产生一个食物，关于函数里面的参数看不懂的可以看看之前的，或者找度娘

void MakeFood(Snake* pSnakeHead);

Snake* g_sFood=new Snake;

然后在main 函数外定义，可以看出来食物并不是被吃了后消失，而是被吃了后改变了位置，但是效果就是消失的，因为这里的设定并不是很复杂，所以这样就够了

void MakeFood(Snake* pSnakeHead)
{
	Snake* pCurNode = pSnakeHead;
	g_sFood->iRow = rand() % 18 + 1;
	g_sFood->iCol = rand() % 38 + 1;
	//当食物产生到蛇的身上
	while (nullptr != pCurNode)
	{
		if (g_sFood->iRow == pCurNode->iRow&&g_sFood->iCol == pCurNode->iCol)
		{
			MakeFood(pSnakeHead);
			break;
		}
		pCurNode = pCurNode->pNext;
	}
	//无敌版本
	/*g_sFood.iRow = g_arrSnake[0].iRow ;
	g_sFood.iCol = g_arrSnake[0].iCol;*/
	/*for (int m = 0; m <VecSnake.size(); ++m)
	{
		if (g_sFood->iRow == VecSnake[m]->iRow && g_sFood->iCol == VecSnake[m]->iCol)
		{
			MakeFood();
			break;
		}
	}*/
}

---

5.蛇吃食物

接下来就是判断是否吃到食物了，到这一步可能又一筹莫展了。但其实换个思路，如果没一帧我们都去判断蛇头与食物是否在同一位置，在一起就算吃到食物了，吃到食物后就调用一次上面的 makeFood()函数，这样理论上就能完成一个完整的游戏了。

那么继续定义一个函数，要习惯这种方式，因为逻辑性会很高，对大型项目就不容易乱，并且在实际项目中的团队互动性会很好

void IsChangeFood(Snake*& pSnakeHead, Snake*& pSnakeBody);

接着定义了

void IsChangeFood(Snake*& pSnakeHead, Snake*& pSnakeBody)
{
    //蛇头的坐标与食物的坐标重叠
	if (pSnakeHead->iRow == g_sFood->iRow&&pSnakeHead->iCol == g_sFood->iCol)
	{
        //蛇的身体数量+1,
		Snake* snake = new Snake();
		pSnakeBody->pNext = snake;
		pSnakeBody = snake;
        //产生新的食物
		MakeFood(pSnakeHead);
        //分数加1
		g_iGrade++;
	}
}

然后就是在 while（true）里加入这个函数就可以了

---

6.判断死亡

天下没有不散的宴席，游戏也有结束的时候，但是判断游戏结束是需要自己写的，因为这时候当蛇跑出屏幕外的时候我们会觉得已经结束了，但实际上蛇还是一直在走，只是没显示在屏幕里而已，但是蛇又会在什么时候停止下来呢，当然是你停止调试或者程序崩溃的时候。

那么我们要怎么判断死亡呢。

1.蛇头撞到墙

2.蛇头撞到蛇身

作为一个敲代码的程序员上面的是不需要你去考虑的，你只需要怎么去实现这个功能。

声明函数。。。

//判断蛇是否存活
bool IsLive(Snake*& pSnakeHead);

定义函数

bool IsLive(Snake*& pSnakeHead)
{
    //将蛇头传进来，然后去遍历整个蛇身，如果蛇头撞到蛇身就返回false
    //这里没写撞墙
	Snake* pCurNode = pSnakeHead->pNext;
	while (nullptr!=pCurNode)
	{
		if (pSnakeHead->iRow == pCurNode->iRow&&pSnakeHead->iCol == pCurNode->iCol)
		{
			return false;
		}
		pCurNode = pCurNode->pNext;
	}

		return true;
}

好了，只要在while（true）里调用这个函数就好了

   //判断是否结束游戏
		if (!IsLive(pSnakeHead))
		{
			cout << "Game Over";
            //这里只是写了让程序暂停，让控制台关闭的函数也是有的，
			system("pause");
			break;
		}
