I have the following code:
colors.hpp:
#ifndef COLORS_HPP
#define COLORS_HPP
#include <SFML/Graphics/Color.hpp>
namespace Colors
{
extern const sf::Color Global;
extern const sf::Colot Text;
}
#endif // COLORS_HPP
colors.cpp:
#include "colors.hpp"
namespace Colors
{
const sf::Color Global(50, 50, 50, 255);
const sf::Color Text(255, 255, 255, 255);
}
And so I wanted to know if there was a way to load the values for those variables from a file on the computer, like for example "colors.txt". I know I could use a class, but I want these variables to be accessible in the whole program by just including "colors.hpp".
I would try something like this
#include "colors.hpp"
sf::Color loadFromFile(std::string const& filename) {
sf::Color result;
// open file 'filename'
// update result
return result;
}
namespace Colors
{
const sf::Color Global{loadFromFile("file1")};
const sf::Color Text{loadFromFile("file2")};
}
