SFML跑酷小游戏【代码加解析】！

以下是一个简单的C++跑酷游戏代码示例，使用SFML库实现。这个游戏包含一个玩家角色（方块）、障碍物（矩形）和基本的跳跃机制：

#include <SFML/Graphics.hpp>
#include <vector>
#include <cstdlib>
#include <ctime>

const int WINDOW_WIDTH = 800;
const int WINDOW_HEIGHT = 600;
const float GRAVITY = 0.6f;
const float JUMP_FORCE = -15.0f;
const float OBSTACLE_SPEED = 5.0f;

class Player {
   
   
public:
    sf::RectangleShape shape;
    float velocityY;

    Player() {
   
   
        shape.setSize(sf::Vector2f(50, 50));
        shape.setFillColor(sf::Color::Green);
        shape.setPosition(100, WINDOW_HEIGHT - 150);
        velocityY = 0;
    }

    void update() {
   
   
        // 应用重力
        velocityY += GRAVITY;
        shape.move(0, velocityY);

        // 地面碰撞检测
        if (shape.getPosition().y > WINDOW_HEIGHT - 150) {
   
   
            shape.setPosition(100, WINDOW_HEIGHT - 150);
            velocityY = 0;
        }
    }

    void jump() {
   
   
        if (shape.getPosition().y >= WINDOW_HEIGHT - 150) {
   
   
            velocityY = JUMP_FORCE;
        }
    }
};

class Obstacle {
   
   
public:
    sf::RectangleShape shape;
    bool passed = false;

    Obstacle(float x) {
   
   
        shape.setSize(sf::Vector2f(30, 80 + rand() % 100));
        shape.setFillColor(sf::Color::Red);
        shape.setPosition(x, WINDOW_HEIGHT - shape.getSize().y);
    }

    void update() {
   
   
        shape.move(-OBSTACLE_SPEED, 0);
    }
};

int main() {
   
   
    srand(time(0));
