 【更新内容每日废话

关卡数量没变,每个都微调了一下。作者再此保证能过,都测试过,过不了技术问题

新增了一个暂停功能,如果不小心选错关可以用'x'或'X'进入暂停界面选择退出,不用重开了

重磅消息:

我终于学会文件操作了,预计可以在4.0.0之前写出存档!!!

哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈​​​​​​​哈哈!!!

### C++ 和 SFML 3.0.0 的游戏开发基础 SFML (Simple and Fast Multimedia Library) 是一个跨平台的多媒体库,广泛应用于2D图形、音频处理以及输入设备管理等领域。以下是基于 SFML 3.0.0 进行游戏开发的一些核心概念和示例代码。 #### 使用 SFML 创建基本的游戏循环 以下是一个简单的程序框架,展示了如何设置窗口并实现基本事件监听机制: ```cpp #include <SFML/Graphics.hpp> const int WINDOW_WIDTH = 800; const int WINDOW_HEIGHT = 600; int main() { sf::RenderWindow window(sf::VideoMode(WINDOW_WIDTH, WINDOW_HEIGHT), "Game Window"); while (window.isOpen()) { sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } window.clear(); // 清除屏幕内容 // 添加绘制逻辑 window.display(); // 显示当前帧 } return 0; } ``` 上述代码创建了一个固定大小的窗口,并通过 `pollEvent` 方法捕获关闭窗口的操作[^1]。 --- #### 绘制简单形状 可以利用 SFML 提供的功能来绘制各种几何形状,例如矩形或圆形: ```cpp sf::RectangleShape rectangle(sf::Vector2f(100.f, 50.f)); // 定义矩形尺寸 rectangle.setFillColor(sf::Color::Green); // 设置颜色 rectangle.setPosition((WINDOW_WIDTH / 2) - 50, (WINDOW_HEIGHT / 2) - 25); // 居中显示 while (window.isOpen()) { sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } window.clear(); window.draw(rectangle); // 绘制矩形到屏幕上 window.display(); } ``` 此部分扩展了之前的代码,在窗口中央绘制绿色矩形。 --- #### 加载纹理与精灵 为了在游戏中加载图片资源,可以使用 `sf::Texture` 类配合 `sf::Sprite` 来完成: ```cpp sf::Texture texture; if (!texture.loadFromFile("path/to/image.png")) // 替换为实际路径 { std::cerr << "Failed to load texture!" << std::endl; } sf::Sprite sprite(texture); sprite.setScale(0.5f, 0.5f); // 缩放比例 sprite.setPosition(100, 100); while (window.isOpen()) { sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } window.clear(); window.draw(sprite); // 将精灵渲染至屏幕 window.display(); } ``` 这段代码演示了如何加载外部图像文件作为纹理,并将其应用到精灵对象上。 --- #### 处理键盘输入 可以通过检测按键状态控制游戏角色移动或其他交互行为: ```cpp float speed = 200.0f; // 移动速度(像素/秒) sf::Clock clock; while (window.isOpen()) { float deltaTime = clock.restart().asSeconds(); sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up)) sprite.move(0, -speed * deltaTime); if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down)) sprite.move(0, speed * deltaTime); if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left)) sprite.move(-speed * deltaTime, 0); if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right)) sprite.move(speed * deltaTime, 0); window.clear(); window.draw(sprite); window.display(); } ``` 这里引入时间间隔计算 (`deltaTime`) 来确保不同硬件上的运动一致性。 --- ### 性能优化建议 对于更复杂的应用场景,应考虑以下几个方面: - **减少不必要的重新分配内存操作**:提前初始化容器类变量。 - **异步线程支持**:如果涉及长时间运行的任务,则可采用多线程技术提升响应效率。 - **缓存常用数据结构**:比如预加载所有可能使用的音效和字体等资源。 ---
