General / Is this good beginner code?

« on: July 18, 2019, 11:08:54 pm »

I recently started programming withh C++.
What do you thing about my code?
Do you have any ideas to improve it?

surce.cpp

#include <SFML/Graphics.hpp>
#include <iostream>
#include "movePlayer.h"

//global variables
float speed = 5.0f;

int main()
{
        //game objects
        sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
        sf::RectangleShape shape(sf::Vector2f(10.0f, 10.0f));
        shape.setFillColor(sf::Color::Cyan);
        window.setFramerateLimit(50);

        while (window.isOpen())
        {
                //close window if closed
                sf::Event event;
                while (window.pollEvent(event))
                {
                        if (event.type == sf::Event::Closed)
                                window.close();
                }

                //move player
                shape.move(inputMoveVector());

                //draw window
                window.clear();
                window.draw(shape);
                window.display();
        }

        return 0;
}
 

movePlayer.h

#pragma once
#include <SFML/Graphics.hpp>
#include <iostream>

extern float speed;

//give out a Vector2f
sf::Vector2f inputMoveVector() {

        float x = 0.0f;
        float y = 0.0f;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
                x = speed;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
                x = -speed;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
                y = -speed;

        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
                y = speed;

        return sf::Vector2f(x, y);

}
