Hello, I'm relatively new to SFML and find myself stuck on what seems like a simple problem.
I'm trying to store a pointer in a class to a sf::Font defined in main. However, it doesn't seem to be dereferencing properly, or is perhaps pointing to NULL? - although, if it is, I can't work out why!
Any help would be
massively appreciated.
Here's a small amount of code which reproduces the problem.
#ifndef __GUARD_FONTSTORAGE
#define __GUARD_FONTSTORAGE
// header file for FontStorage class
#include <SFML/Graphics.hpp>
class FontStorage
{
public:
void setFont(sf::Font& new_font) { font_pointer = &new_font; }
sf::Font getFont() const { return *font_pointer; }
private:
sf::Font* font_pointer;
};
#endif
Main function:
#include <SFML/Graphics.hpp>
#include "FontStorage.hpp"
using namespace sf;
int main()
{
// render the window
RenderWindow window(VideoMode(800, 500), "Font Testing");
window.setFramerateLimit(50);
// store a font in our FontStorage class
Font font;
font.loadFromFile("fonts/DejaVuSans.ttf");
FontStorage font_store;
font_store.setFont(font);
// set up some text to test
Text test_text;
test_text.setString("Greased lightning! Go, Greased lighting!");
test_text.setFillColor(Color::Red);
test_text.setPosition(100,100);
test_text.setFont(font_store.getFont());
test_text.setCharacterSize(30);
// main loop
while(window.isOpen())
{
//Poll events
Event event;
while(window.pollEvent(event))
{
if(event.type == Event::Closed)
window.close();
}
// draw to the window
window.clear();
window.draw(test_text);
window.display();
} // end main loop
return 0;
}
Nothing displays with the above code, but if you set the font directly rather than through the FontStorage instance, it displays fine.
