用c++写能穿墙,能加速的贪吃蛇代码

以下是一个简单的能穿墙、能加速的贪吃蛇代码，使用了C++语言和SFML库实现：

#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>

int main()
{
    // 创建窗口
    sf::RenderWindow window(sf::VideoMode(800, 600), "Snake Game");

    // 设置帧率
    window.setFramerateLimit(60);

    // 创建蛇头
    sf::RectangleShape head(sf::Vector2f(20, 20));
    head.setFillColor(sf::Color::Green);
    head.setPosition(400, 300);

    // 创建蛇身
    std::vector<sf::RectangleShape> body;
    for(int i = 0; i < 3; i++) {
        body.emplace_back(sf::Vector2f(20, 20));
        body.back().setFillColor(sf::Color::Green);
        body.back().setPosition(380-i*20, 300);
    }

    // 初始化移动方向
    int direction = 0; // 0: 向右, 1: 向下, 2: 向左, 3: 向上

    // 初始化加速
    bool speedUp = false;

    // 游戏循环
    while (window.isOpen()) {
        // 处理事件
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }
            if (event.type == sf::Event::KeyPressed) {
                if (event.key.code == sf::Keyboard::Right && direction != 2) {
                    direction = 0;
                }
                if (event.key.code == sf::Keyboard::Down && direction != 3) {
                    direction = 1;
                }
                if (event.key.code == sf::Keyboard::Left && direction != 0) {
                    direction = 2;
                }
                if (event.key.code == sf::Keyboard::Up && direction != 1) {
                    direction = 3;
                }
                if (event.key.code == sf::Keyboard::Space) {
                    speedUp = true;
                }
            }
            if (event.type == sf::Event::KeyReleased) {
                if (event.key.code == sf::Keyboard::Space) {
                    speedUp = false;
                }
            }
        }

        // 移动蛇头
        if (direction == 0) {
            head.move(2*(speedUp?2:1), 0);
        } else if (direction == 1) {
            head.move(0, 2*(speedUp?2:1));
        } else if (direction == 2) {
            head.move(-2*(speedUp?2:1), 0);
        } else if (direction == 3) {
            head.move(0, -2*(speedUp?2:1));
        }

        // 穿墙
        if (head.getPosition().x > 800) {
            head.setPosition(0, head.getPosition().y);
        }
        if (head.getPosition().x < 0) {
            head.setPosition(800, head.getPosition().y);
        }
        if (head.getPosition().y > 600) {
            head.setPosition(head.getPosition().x, 0);
        }
        if (head.getPosition().y < 0) {
            head.setPosition(head.getPosition().x, 600);
        }

        // 移动蛇身
        for (int i = body.size()-1; i > 0; i--) {
            body[i].setPosition(body[i-1].getPosition());
        }
        body[0].setPosition(head.getPosition());

        // 检测蛇头和蛇身是否碰撞
        for (auto& part : body) {
            if (head.getGlobalBounds().intersects(part.getGlobalBounds())) {
                std::cout << "Game Over!" << std::endl;
                window.close();
            }
        }

        // 渲染
        window.clear();
        window.draw(head);
        for (auto& part : body) {
            window.draw(part);
        }
        window.display();
    }

    return 0;
}

这段代码使用了SFML库来实现窗口、图形等的操作。游戏循环中处理了事件、移动蛇头和蛇身、碰撞检测等逻辑，并在循环中渲染了游戏画面。其中，穿墙逻辑通过判断蛇头是否超出窗口边界来实现，加速逻辑通过按下空格键来切换加速状态来实现。
