好久不见啊同志们！！！
写了个《贪吃蛇》的代码，本来想早点作的结果忘了………………
上代码：
#include#include#include#include#include#include #define clear() cout << "\\033c" << flush using namespace std; struct node { int x, y; }; int num[15][15]; int x, y; node head, food; bool Food = false; listsnake; char ch = 0; int score = 0; static struct termios initial_settings, new_settings; static int peek_character = -1; void init_keyboard(); void close_keyboard(); bool kbhit(); char readch(); void changeNum(); void drawBoard(); void move(); int scanKeyboard(); void init_snake(); void fullFood(); bool getFood(); void longer(); bool gameOver(); void intro(); int getch(); // 不回显函数 //主函数 int main() { init_snake(); //初始化蛇 init_keyboard(); //初始化键盘 x = 0, y = 0; //初始化移动方向 intro(); //介绍游戏规则 char a = getch(); fullFood(); //填充食物 drawBoard(); //绘制游戏界面 while(ch != 'n') { usleep(200000); if(kbhit()) //如果按下按键 { ch = readch(); //读取按键值 } int nx = x, ny = y; if (ch == 'w') nx = -1,ny = 0; //预设移动方向 if (ch == 's') nx = 1, ny = 0; if (ch == 'a') nx = 0, ny = -1; if (ch == 'd') nx = 0, ny = 1; if (ch == 'n') return 0; if (nx != -x || ny != -y) x = nx, y = ny; if (getFood()) { score++; longer(); fullFood(); } else move(); if (gameOver()) { drawBoard(); cout << "GameOver!!" << endl; return 0; } drawBoard(); } close_keyboard(); return 0; } bool gameOver() { head = snake.front(); if (head.x <= 0 || head.x > 12) return true; if (head.y <= 0 || head.y > 12) return true; if (num[head.x][head.y] == 1) return true; return false; } void init_keyboard() { tcgetattr(0,&initial_settings); new_settings = initial_settings; new_settings.c_lflag &= ~ICANON; new_settings.c_lflag &= ~ECHO; new_settings.c_lflag &= ~ISIG; new_settings.c_cc[VMIN] = 1; new_settings.c_cc[VTIME] = 0; tcsetattr(0, TCSANOW, &new_settings); } void close_keyboard() { tcsetattr(0, TCSANOW, &initial_settings); } bool kbhit() { char ch; int nread; if(peek_character != -1) return 1; new_settings.c_cc[VMIN]=0; tcsetattr(0, TCSANOW, &new_settings); nread = read(0,&ch,1); new_settings.c_cc[VMIN]=1; tcsetattr(0, TCSANOW, &new_settings); if(nread == 1) { peek_character = ch; return 1; } return 0; } char readch() { char ch; if(peek_character != -1) { ch = peek_character; peek_character = -1; return ch; } read(0,&ch,1); return ch; } void fullFood() // 填充数据 { int x[200] = {}, y[200] = {}, cur = 0; for (int i = 1; i <= 12; i++) { for (int j = 1; j <= 12; j++) { if (num[i][j] == 0) { cur++; x[cur] = i; y[cur] = j; } } } if (cur > 0) // 还有空位 { srand(time(0)); int cc = rand() % cur + 1; // 随机从空位中取出一个 food.x = x[cc]; food.y = y[cc]; } } void changeNum() { if(snake.empty()) return; memset(num, 0, sizeof(num)); for (auto pos = snake.begin(); pos != snake.end(); pos++) { num[(*pos).x][(*pos).y] = 1; } num[food.x][food.y] = 3; auto pos = snake.begin(); num[(*pos).x][(*pos).y] = 2; } void drawBoard() // 打印当前表格 { changeNum(); clear(); cout << " ╔"; for (int i = 1; i <= 6; i++) cout << "════"; cout << "═╗\n"; // 输出中间部分 for (int i = 1; i <= 12; i++) // 行 { cout << " ║"; for (int j = 1; j <= 12; j++) // 列 { if (num[i][j] == 1) cout << "\033[41m \033[0m"; else if (num[i][j] == 2) cout << "\033[42m \033[0m"; else if (num[i][j] == 3) cout << "\033[43m \033[0m"; else cout << " "; } cout << " ║" << endl; } cout << " ╚"; for (int i = 1; i <= 6; i++) cout << "════"; cout << "═╝\n"; cout << "score:" << score << endl; } void move() { clear(); if (x == 0 && y == 0) { drawBoard(); return; } node next = snake.front(); next.y += y; next.x += x; snake.pop_back(); snake.push_front(next); } int scanKeyboard() { int in; struct termios new_settings; struct termios stored_settings; tcgetattr(0,&stored_settings); new_settings = stored_settings; new_settings.c_lflag &= (~ICANON); new_settings.c_cc[VTIME] = 0; tcgetattr(0,&stored_settings); new_settings.c_cc[VMIN] = 1; tcsetattr(0,TCSANOW,&new_settings); in = getchar(); tcsetattr(0,TCSANOW,&stored_settings); return in; } void init_snake() { head.x = 1, head.y = 1; snake.push_back(head); for (int i = 2; i <= 4; i++) { node a; a.x = 1, a.y = i; snake.push_back(a); } changeNum(); } bool getFood() { head = snake.front(); if(num[head.x + x][head.y + y] == 3) return true; else return false; } void longer() { node temp = snake.front(); temp.x += x; temp.y += y; snake.push_front(temp); } void intro() { cout << "欢迎来到贪吃蛇小游戏" << endl; cout << "游戏规则介绍：" << endl; cout << "你可以使用w,a,s,d来控制贪吃蛇进行上下左右的移动" << endl; cout << "在移动过程中，每吃到一个果子，你就能增加1分，同时你也会变长 1 格" << endl; cout << "但，如果你在移动过程中碰到了自己或者墙壁，那么你就GAMEOVER了！" << endl; cout << "当然，你也可以按下 n 键提前结束游戏。好了，现在按下任意键开始游戏吧！" << endl; } int getch() { struct termios nts, ots; // 得到当前终端(0表示标准输入)的设置 if (tcgetattr(0, &ots) < 0) return EOF; // 设置终端为Raw原始模式，该模式下所有的输入数据以字节为单位被处理 nts = ots; cfmakeraw(&nts); // 设置上更改之后的设置 if (tcsetattr(0, TCSANOW, &nts) < 0) return EOF; // 设置还原成老的模式 int cr; cr = getchar(); if (tcsetattr(0, TCSANOW, &ots) < 0) return EOF; return cr; }
好啦，代码上完了，呢么本期文章就结束了，拜拜！！！
