C语言实现2048游戏
- 前置需要安装的库
libnucrses5-dev
- 引入头文件
#include <stdio.h>
#include <stdlib.h>
#include <curses.h>
#include <unistd.h>
#include <signal.h>
#include <time.h>
- 创建全局变量
// 游戏主界面是一个 4*4 的 16 宫格，使用二维数组进行表示，用 0 表示空格
int a[4][4] = {0};
// 16 宫格中空格的个数
int empty;
int old_y, old_x;
- 函数原型
void draw(); // 用于绘制游戏界面
void play(); // 游戏运行的逻辑主体
void init(); // 初始化函数，用于完成一些必要的初始化操作
void draw_one(int y, int x); // 绘制单个数字
void cnt_value(int *new_y, int *new_x);
int game_over(); // 结束游戏
int cnt_one(int y, int x);
- main函数
int main()
{
init();
play();
endwin();
return 0;
}
- init函数
void init()
{
int x, y;
initscr();
cbreak();
noecho();
curs_set(0);
empty = 15;
srand(time(0));
x = rand() % 4;
y = rand() % 4;
a[y][x] = 2;
draw();
}
- draw函数
void draw()
{
int n, m, x, y;
char c[4] = {'0', '0', '0', '0'};
clear();
for(n = 0; n < 9; n += 2) //绘制横线，n代表行，m代表列
{
for(m = 0; m < 21; m++)
{

addch('-');
refresh();
}
}
for(m = 0; m < 22; m += 5) //绘制竖线
{

}
for(y = 0; y < 4; y++) //绘制数字
{
for(x = 0; x < 4; x++)
{
draw_one(y, x);
}
}
}
- draw_one函数：用于绘制单个数字
void draw_one(int y, int x)
{
int i, m, k, j;
char c[5] = {0x00};
i = a[y][x];
m = 0;
while(i > 0)

k--;
}
}
