飞机大战c++实现类的代码

以下是一个简单的飞机大战C++类的代码示例，仅供参考：

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

using namespace sf;

class Bullet {
public:
    RectangleShape shape;
    Vector2f currVelocity;

    Bullet(float posX, float posY) {
        shape.setSize(Vector2f(2.f, 10.f));
        shape.setPosition(posX, posY);
        shape.setFillColor(Color::Yellow);
        currVelocity = Vector2f(0.f, -800.f);
    }
};

class Player {
public:
    RectangleShape shape;
    Vector2f currVelocity;
    float speed;

    Player(float posX, float posY) {
        shape.setSize(Vector2f(50.f, 50.f));
        shape.setPosition(posX, posY);
        shape.setFillColor(Color::Cyan);
        currVelocity = Vector2f(0.f, 0.f);
        speed = 500.f;
    }

    void update() {
        shape.move(currVelocity * speed * deltaTime.asSeconds());
    }

    void shoot() {
        Bullet bullet(shape.getPosition().x + shape.getSize().x / 2.f, shape.getPosition().y);
        bullets.push_back(bullet);
    }

    std::vector<Bullet> bullets;
};

class Enemy {
public:
    RectangleShape shape;
    Vector2f currVelocity;

    Enemy(float posX, float posY) {
        shape.setSize(Vector2f(50.f, 50.f));
        shape.setPosition(posX, posY);
        shape.setFillColor(Color::Red);
        currVelocity = Vector2f(0.f, 200.f);
    }

    void update() {
        shape.move(currVelocity * deltaTime.asSeconds());
    }
};

int main() {
    RenderWindow window(VideoMode(800, 600), "飞机大战");

    Player player(375.f, 500.f);
    Enemy enemy(375.f, 50.f);

    Clock clock;
    while (window.isOpen()) {
        deltaTime = clock.restart();

        Event event;
        while (window.pollEvent(event)) {
            if (event.type == Event::Closed) {
                window.close();
            }
            if (event.type == Event::KeyPressed) {
                if (event.key.code == Keyboard::Space) {
                    player.shoot();
                }
            }
        }

        if (Keyboard::isKeyPressed(Keyboard::A)) {
            player.currVelocity.x = -1.f;
        }
        else if (Keyboard::isKeyPressed(Keyboard::D)) {
            player.currVelocity.x = 1.f;
        }
        else {
            player.currVelocity.x = 0.f;
        }

        if (player.shape.getPosition().x <= 0.f) {
            player.shape.setPosition(0.f, player.shape.getPosition().y);
        }
        if (player.shape.getPosition().x >= window.getSize().x - player.shape.getSize().x) {
            player.shape.setPosition(window.getSize().x - player.shape.getSize().x, player.shape.getPosition().y);
        }

        player.update();
        enemy.update();

        for (size_t i = 0; i < player.bullets.size(); i++) {
            player.bullets[i].shape.move(player.bullets[i].currVelocity * deltaTime.asSeconds());
            if (player.bullets[i].shape.getPosition().y <= 0.f) {
                player.bullets.erase(player.bullets.begin() + i);
            }
        }

        window.clear();

        window.draw(player.shape);

        for (size_t i = 0; i < player.bullets.size(); i++) {
            window.draw(player.bullets[i].shape);
        }

        window.draw(enemy.shape);

        window.display();
    }

    return 0;
}

上面的代码实现了一个简单的飞机大战游戏，包括玩家、敌机和子弹等元素。其中，玩家可以通过键盘控制飞机的移动和攻击，敌机会自动向下移动，子弹会向上移动。注意，这只是一个简单的示例，具体实现还需要根据具体需求进行修改和完善。
