效果

按方向键移动
按空格加速
按esc暂停
按两次esc退出
随着蛇的长度增加，蛇移动速度加快
没有屏闪

main()

int main()
{ 
   
	Init();							//初始化
	while (!die)
	{ 
   
		ProcessKey();				//处理按键
		Move();						//移动蛇
		Judge();					//碰撞检测
		Draw();						//画图
		Sleep(snack.timeperstep);	//延时
	}
	while (_getch() != 27);			//游戏结束后按esc退出
}

Init()

void Init()
{ 
   
	SetConsoleTitleW(L"贪吃蛇");
	system("MODE CON: COLS=64 LINES=32");
	snack.body.push_back(new COORD{ 
    15,15});
	snack.body.push_back(new COORD{ 
    14,15 });
	GenerateFood();
}

ProcessKey()

这里有坑，方向键会产生两个键码，所以要用两次getch。方向键会先产生-32键码，然后产生72 75 77 80这四个键码中的一个

void ProcessKey()
{ 
   
	Direction before = snack.heading;
	snack.timeperstep = 1000 / snack.body.size();
	char ch1, ch2;
	while (_kbhit())
	{ 
   
		ch1 = _getch();
		switch (ch1)
		{ 
   
		case VK_ESCAPE:
			if (_getch() == 27)exit(0);
			break;
		case -32:
			switch (ch2 = _getch())
			{ 
   
			case 72://up
				if (Direction::down != before)
					snack.heading = Direction::up;
				break;
			case 80://down
				if (Direction::up != before)
					snack.heading = Direction::down;
				break;
			case 75://left
				if (Direction::right != before)
					snack.heading = Direction::left;
				break;
			case 77://right
				if (Direction::left != before)
					snack.heading = Direction::right;
			}
			break;
		case VK_SPACE:
			snack.timeperstep = snack.timeperstep = 300 / snack.body.size();;
		}
	}
}

Move()

这里只是把头往前移动了一格

void Move()
{ 
   
	COORD* head = snack.body.front();
	switch (snack.heading)
	{ 
   
	case Direction::up:
		snack.body.push_front(new COORD{ 
    head->X,head->Y - 1 });
		break;
	case Direction::down:
		snack.body.push_front(new COORD{ 
    head->X,head->Y + 1 });
		break;
	case Direction::left:
		snack.body.push_front(new COORD{ 
    head->X - 1,head->Y });
		break;
	case Direction::right:
		snack.body.push_front(new COORD{ 
    head->X + 1,head->Y });
		break;
	}
}

Judge()

判断头有没有和食物、墙、身体重叠。这里的坑就是判断身体的时候，一定要掐头去尾来判断

void Judge()
{ 
   
	COORD* head = snack.body.front();
	if (food.X == head->X && food.Y == head->Y)
		GenerateFood();
	else if (head->X < 0 || head->Y < 0 || head->X == 30 || head->Y == 30)
		die = true;
	else
	{ 
   
		delete snack.body.back();
		snack.body.pop_back();
		for (list<COORD*>::iterator i = ++snack.body.begin(); i != snack.body.end(); i++)
		{ 
   
			if ((*i)->X == head->X && (*i)->Y == head->Y)
				die = true;
		}
	}
}

Draw()

用缓冲，先把要输出到屏幕的东西写道缓冲区，解决屏闪。大致顺序是先画墙，再画食物，再画蛇，如果蛇死了就再画一个lost

void Draw()
{ 
   
	HANDLE houtbuf = CreateConsoleScreenBuffer(GENERIC_WRITE, FILE_SHARE_WRITE, NULL, CONSOLE_TEXTMODE_BUFFER, NULL);
	CONSOLE_CURSOR_INFO cci{ 
    25,0 };
	SetConsoleCursorInfo(houtbuf, &cci);
	DWORD NumberOfCharsWritten;
	COORD coord;
	coord.Y = 0;
	for (coord.X = 0; coord.X < 64; coord.X += 2)
	{ 
   
		WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	}
	coord.Y = 31;
	for (coord.X = 0; coord.X < 64; coord.X += 2)
	{ 
   
		WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	}
	coord.X = 0;
	for (coord.Y = 0; coord.Y < 32; coord.Y++)
	{ 
   
		WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	}
	coord.X = 62;
	for (coord.Y = 0; coord.Y < 32; coord.Y++)
	{ 
   
		WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	}
	coord.Y = food.Y + 1;
	coord.X = (food.X + 1) * 2;
	FillConsoleOutputAttribute(houtbuf, FOREGROUND_BLUE, 2, coord, &NumberOfCharsWritten);
	WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	for (COORD* node : snack.body)
	{ 
   
		coord.X = (1 + node->X) * 2;
		coord.Y = 1 + node->Y;
		FillConsoleOutputAttribute(houtbuf, FOREGROUND_GREEN, 2, coord, &NumberOfCharsWritten);
		WriteConsoleOutputCharacterW(houtbuf, L"■", 1, coord, &NumberOfCharsWritten);
	}
	if (die)
	{ 
   
		coord.Y = 16;
		coord.X = 28;
		FillConsoleOutputAttribute(houtbuf, FOREGROUND_RED, 8, coord, &NumberOfCharsWritten);
		WriteConsoleOutputCharacterW(houtbuf, L"##LOST##", 8, coord, &NumberOfCharsWritten);
		die = true;
	}
	SetConsoleActiveScreenBuffer(houtbuf);
}

GenerateFood()

用来生成一个和蛇身不重叠的食物

void GenerateFood()
{ 
   
	unfished:
	food.X = rand() % 30;
	food.Y = rand() % 30;
	for (COORD* node : snack.body)
	{ 
   
		if (node->X == food.X && node->Y == food.Y)
			goto unfished;
	}
}

所有代码

#include <Windows.h>
#include <iostream>
#include <cstdlib>
#include <conio.h>
#include <list>
using namespace std;
enum Direction { 
    up, down, left, right };
struct { 
   
	list<COORD*> body;
	Direction heading = Direction::right;
	int timeperstep;
}snack;
COORD food;
bool die;
void ProcessKey()
{ 
   
	Direction before = snack.heading;
	snack.timeperstep = 1000 / snack.body.size();
	char ch1, ch2;
	while (_kbhit())
	{ 
   
		ch1 = _getch();
		switch (ch1)
		{ 
   
		case VK_ESCAPE:
			if (_getch() == 27)exit(0);
			break;
		case -32:
			switch (ch2 = _getch())
			{ 
   
			case 72://up
				if (Direction::down != before)
					snack.heading = Direction::up;
				break;
			case 80://down
				if (Direction::up != before)
					snack.heading = Direction::down;
				break;
			case 75://left
				if (Direction::right != before)
					snack.heading = Direction::left;
				break;
			case 77://right
				if (Direction::left != before)
					snack.heading = Direction::right;
			}
			break;
		case VK_SPACE:
			snack.timeperstep = snack.timeperstep = 300 / snack.body.size();;
		}
