本文实例为大家分享了C++控制台循环链表实现贪吃蛇的具体代码，供大家参考，具体内容如下

-stdafx.h 为了简化程序定义一些宏和全局变量

#ifndef __STDAFX_H__#define __STDAFX_H__ // ============上下左右=============const int UP = 72;const int DOWN = 80;const int LEFT = 75;const int RIGHT = 77; // ==============宽高===============#define HEIGHT 20#define WIDTH 39 // ==============输出===============#define cout_food std::cout<<"＊"#define cout_snake std::cout<<"■"#define cout_space std::cout << " "#define cout_snake_xy(x,y) SnakeUI::gotoXY(x,y);cout_snake#define cout_food_xy(x,y) SnakeUI::gotoXY(x,y);cout_food#define cout_space_xy(x,y) SnakeUI::gotoXY(x,y);cout_space // =============结束？==============#define OVER false#define RUN true #endif

-SnakeUI.h

主要是初始化UI，初始化蛇，还有生产食物，判断食物和蛇有没有相撞，还有对界面的一些操作

#ifndef __SNAKE_UI_H__#define __SNAKE_UI_H__ #include <iostream>#include <Windows.h>#include "Snake.h" struct Food { int x; int y;}; class SnakeUI {public: static void initUI(); static void initSnake(); static void gotoXY(int x, int y); static void productFood(Snake& snake); static bool meetWithFood(int x, int y); private: static Food food; }; #endif

-SnakeUI.cpp

#include "stdafx.h"#include "SnakeUI.h"#include <ctime>using namespace std; Food SnakeUI::food = { 0, 0 }; // init UIvoid SnakeUI::initUI() { cout << "┏"; for (int i = 1; i < WIDTH; ++i) cout << "━"; cout << "┓"; gotoXY(0, HEIGHT); cout << "┗"; for (int i = 1; i < WIDTH; ++i) cout << "━"; cout << "┛"; for (int y = 1; y < HEIGHT; ++y) { gotoXY(0, y); cout << "┃"; gotoXY(WIDTH, y); cout << "┃"; }} // init snake: three pointsvoid SnakeUI::initSnake() { gotoXY(2, 10); cout_snake; gotoXY(3, 10); cout_snake; gotoXY(4, 10); cout_snake;} // goto point(x, y) in consolevoid SnakeUI::gotoXY(int x, int y) { COORD coord = { x * 2, y }; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);} // random product foodvoid SnakeUI::productFood(Snake& snake) { srand((unsigned)time(NULL)); int x, y; // x from 1 to 38, y from 1 to 19 bool productOK; for (;;) { productOK = true; x = rand() % 38 + 1; y = rand() % 19 + 1; // 不和蛇身碰撞1->检查身体和尾部 for (SnakeNode* sn = snake.last; sn != snake.first; sn = sn->prev) { if (sn->x == x && sn->y == y) { productOK = false; break; } } // 不和蛇身碰撞2->检查头部 if (x == snake.first->x && y == snake.first->y) productOK = false; if (productOK) break; } food.x = x; food.y = y; cout_food_xy(food.x, food.y);} // is snake's head meet with food?bool SnakeUI::meetWithFood(int x, int y) { return (food.x == x && food.y == y);}

-Snake.h
蛇类，蛇的移动和状态

#ifndef __SNAKE_H__#define __SNAKE_H__ struct SnakeNode { int x; int y; SnakeNode* prev; SnakeNode(int x_t, int y_t){ x = x_t; y = y_t; } SnakeNode(){}}; class Snake { friend class SnakeUI; public: Snake(); ~Snake(); bool snakeMove(char& dir); private: void getKey(char& dir); private: SnakeNode* first; SnakeNode* last; char state;}; #endif

-Snake.cpp

#include "stdafx.h"#include "Snake.h"#include "SnakeUI.h" Snake::Snake() { // 状态：向右 state = RIGHT; // 创建循环链表 first = new SnakeNode(4, 10); last = new SnakeNode(2, 10); last->prev = new SnakeNode(3, 10); last->prev->prev = first; first->prev = last; // UI SnakeUI::initSnake(); SnakeUI::productFood(*this);} Snake::~Snake() { SnakeNode* tmp = last; while (last != last) { last = last->prev; delete tmp; tmp = last; } delete last;} bool Snake::snakeMove(char& dir) { int x = first->x; int y = first->y; getKey(dir); // 撞墙->Game Over switch (state) { case UP: --y; if (y == 0) return OVER; break; case DOWN: ++y; if (y == HEIGHT) return OVER; break; case LEFT: --x; if (x == 0) return OVER; break; case RIGHT: ++x; if (x == WIDTH) return OVER; break; } // 撞到了自己 SnakeNode* tmp = last; for (; tmp != first; tmp = tmp->prev) { if (first->x == tmp->x && first->y == tmp->y) return OVER; } // 吃食物 if (SnakeUI::meetWithFood(x, y)) { SnakeNode* newHead = new SnakeNode(x, y); first->prev = newHead; newHead->prev = last; first = newHead; cout_snake_xy(x, y); SnakeUI::productFood(*this); } else { cout_space_xy(last->x, last->y); last->x = x; last->y = y; first = last; last = last->prev; cout_snake_xy(x, y); } return RUN;} void Snake::getKey(char& dir) { switch (dir) { case UP: if (state == LEFT || state == RIGHT) state = UP; return; case DOWN: if (state == LEFT || state == RIGHT) state = DOWN; return; case LEFT: if (state == UP || state == DOWN) state = LEFT; return; case RIGHT: if (state == UP || state == DOWN) state = RIGHT; return; }}

-main.cpp

#include "stdafx.h"#include "SnakeUI.h"#include "Snake.h"#include <iostream>#include <conio.h>using namespace std; DWORD WINAPI ThreadProc1(LPVOID lpParameter); char dir = RIGHT; int main(){ SnakeUI::initUI(); Snake snake; CreateThread(NULL, 0, ThreadProc1, NULL, 0, NULL); while (snake.snakeMove(dir)) Sleep(100); system("pause"); return 0;} DWORD WINAPI ThreadProc1(LPVOID lpParameter){ for (;;) { dir = _getch(); } return 1; }
