C++ 贪吃蛇小游戏(CLI)

前言

我大二的时候用c写过一个跑出五格就越界的贪吃蛇，现在看来简直是一堆垃圾。
我现在用cplusplus重写它，那就叫它垃圾plusplus好了(狗头）。

设计思路

贪吃蛇行为过程：
1.蛇吃果子
2.蛇以speed运动
3.蛇在ground上运动
4.果子以frquency为间隔出现
5.果子出现在在ground上
6.蛇的头撞到了空气和果子之外的物体会死

实现过程

backg.h文件：

#include<vector>
#include<windows.h>
#include<iostream>
#include<conio.h>
#include<queue>
#include<thread>
#include<random>
#include<time.h>
class backg {
public:
	std::vector<std::vector<int>> ground;
	HANDLE hout;
	backg();
	void jump(int x,int y);
	void plant();
	void startplant();
};

backg.c文件：

#include<backg.h>

	ground = t;
	hout = GetStdHandle(STD_OUTPUT_HANDLE);
	CONSOLE_CURSOR_INFO cursor_info = { 1,0 };
	SetConsoleCursorInfo(hout, &cursor_info);
	int i = 0;
	while (i < m || i < n)
	{
		if (i < m) 
		{ ground[i][0] = ground[i][n - 1] = 1; jump(0, i); std::cout << '|'; jump(n - 1, i); std::cout << '|'; }

		i++;
	}
}
void backg::jump(int x, int y)
{
	COORD coord;
	coord.X = x;
	coord.Y = y;
	SetConsoleCursorPosition(hout, coord);
}
