devc++贪吃蛇代码

以下是一个使用DevC++编写的简单贪吃蛇代码的例子：

#include <iostream>
#include <conio.h>
#include <windows.h>
#include <list>
using namespace std;

HANDLE hand;
COORD dir = {0, 1};
COORD food;
int score = 0;
int level = 1;
int length = 5;
list<COORD> snake;

void init() {
    hand = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_CURSOR_INFO cci;
    cci.bVisible = 0;
    cci.dwSize = sizeof(cci);
    SetConsoleCursorInfo(hand, &cci);
    srand((unsigned)time(NULL));
    food.X = rand() % 30 + 1;
    food.Y = rand() % 20 + 1;
}

void gotoxy(int x, int y) {
    COORD pos;
    pos.X = x;
    pos.Y = y;
    SetConsoleCursorPosition(hand, pos);
}

void drawFood() {
    gotoxy(food.X, food.Y);
    SetConsoleTextAttribute(hand, FOREGROUND_BLUE | FOREGROUND_INTENSITY);
    cout << "F";
}

void drawSnake() {
    for (auto it = snake.begin(); it != snake.end(); ++it) {
        gotoxy((*it).X, (*it).Y);
        SetConsoleTextAttribute(hand, FOREGROUND_GREEN | FOREGROUND_INTENSITY);
        cout << "O";
    }
}

void eraseSnake() {
    for (auto it = snake.begin(); it != snake.end(); ++it) {
        gotoxy((*it).X, (*it).Y);
        cout << " ";
    }
}

void updateSnake() {
    COORD head = snake.front();
    COORD next = {head.X + dir.X, head.Y + dir.Y};
    snake.push_front(next);
    if (next.X == food.X && next.Y == food.Y) {
        score += 10;
        length++;
        food.X = rand() % 30 + 1;
        food.Y = rand() % 20 + 1;
    } else if (snake.size() > length) {
        snake.pop_back();
    }
    if (next.X < 0 || next.X > 31 || next.Y < 0 || next.Y > 21) {
        gameover();
    }
    for (auto it = snake.begin(); it != snake.end(); ++it) {
        if (it != snake.begin() && (*it).X == head.X && (*it).Y == head.Y) {
            gameover();
        }
    }
}

void input() {
    if (_kbhit()) {
        char ch = _getch();
        switch (ch) {
            case 'w':
                if (dir.Y != 1) {
                    dir.X = 0;
                    dir.Y = -1;
                }
                break;
            case 'a':
                if (dir.X != 1) {
                    dir.X = -1;
                    dir.Y = 0;
                }
                break;
            case 's':
                if (dir.Y != -1) {
                    dir.X = 0;
                    dir.Y = 1;
                }
                break;
            case 'd':
                if (dir.X != -1) {
                    dir.X = 1;
                    dir.Y = 0;
                }
                break;
        }
    }
}

void gameover() {
    system("cls");
    gotoxy(15, 10);
    cout << "Game Over!" << endl;
    gotoxy(15, 11);
    cout << "Score: " << score << endl;
    while (_getch() != 13) {}
    exit(0);
}

int main() {
    init();
    while (1) {
        eraseSnake();
        drawFood();
        drawSnake();
        input();
        updateSnake();
        Sleep(200);
    }
    return 0;
}

这段代码使用了Windows API函数和标准库函数来实现贪吃蛇的基本功能。其中使用了`list`容器来存储蛇的身体坐标，通过不断更新蛇的位置来控制蛇的移动。当蛇的头与食物的位置重合时，会增加分数和长度，并生成新的食物。如果蛇撞到墙壁或者撞到自己的身体，游戏结束并显示得分。
