For a small project of mine, I wanted to make a game without any graphics objects and just text. I went to SFML because it seemed the best for me (plus I wanted to brush up my C++). I followed the guide up to creating text and started to branch away. I got to this point, and the text loads just fine.
My main file.
#include <iostream>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
using namespace std;
int main()
{
//Boring window init
cout<<"Creating window..."<<endl;
sf::RenderWindow window(sf::VideoMode(800,600),"Space");
window.setVerticalSyncEnabled(true);
//Font Creation
cout<<"Creating Font..."<<endl;
sf::Font font;
if(!font.loadFromFile("res/font.ttf"))
{
cout<<"Font could not load. Perhaps it doesn't exist?"<<endl;
}
sf::Text text;
text.setFont(font);
text.setPosition(300,300);
text.setString("Hello World");
cout<<"Done."<<endl;
while(window.isOpen())
{
sf::Event event;
while(window.pollEvent(event))
{
if(event.type == sf::Event::Closed)
window.close();
}
window.clear(sf::Color::Black);
window.draw(text);
window.display();
}
cout<<"Finished!"<<endl;
return 0;
}
I went on to create a class so I could create a character of any color at any position. I called it Sprite.
Sprite header
#ifndef SPRITE_H
#define SPRITE_H
#include <SFML/Graphics.hpp>
class Sprite
{
public:
Sprite(char Character, sf::Font font, float r, float g, float b, float x, float y);
void draw(sf::RenderWindow& win);
void updatePosition(float x, float y);
void updateColor(float r, float g, float b);
protected:
char Character;
float r,g,b;
sf::Text text;
};
#endif // SPRITE_H
and the Implementation
#include "Sprite.h"
#include <SFML/Graphics.hpp>
Sprite::Sprite(char Character, sf::Font font, float r, float g, float b, float x, float y)
{
this->Character=Character;
this->r = r;
this->g = g;
this->b = b;
text.setFont(font);
text.setPosition(x,y);
text.setString(Character);
text.setFillColor(sf::Color(r,g,b));
}
void Sprite::draw(sf::RenderWindow& win)
{
win.draw(text);
}
void Sprite::updatePosition(float x, float y)
{
text.setPosition(x,y);
}
void Sprite::updateColor(float r, float g, float b)
{
text.setFillColor(sf::Color(r,g,b));
}
I go to try and create a sprite and see how it works.
Updated main
#include <iostream>
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
#include <Sprite.h>
using namespace std;
int main()
{
//Boring window init
cout<<"Creating window..."<<endl;
sf::RenderWindow window(sf::VideoMode(800,600),"Space");
window.setVerticalSyncEnabled(true);
//Font creation
cout<<"Creating Font..."<<endl;
sf::Font font;
if(!font.loadFromFile("res/font.ttf"))
{
cout<<"Font could not load. Perhaps it doesn't exist?"<<endl;
}
Sprite Star('*', font, 0, 255, 255, 5, 5);
cout<<"Done."<<endl;
while(window.isOpen())
{
sf::Event event;
while(window.pollEvent(event))
{
if(event.type == sf::Event::Closed)
window.close();
}
window.clear(sf::Color::Black);
Star.draw(window);
window.display();
}
cout<<"Finished!"<<endl;
return 0;
}
This is what I get
I tried some things including changing the symbol, changing the char to a string, increasing the font size, and even rewrote the class (this is my second draft of the class). I just can't figure out what's happening. I assume it's the Sprite::draw(sf::RenderWindow& win) that is causing trouble. If so, what's the best way I could draw something from another class onto the window? Thanks!
