Graphics / Issues with drawing an sf::Text vector

« on: August 26, 2015, 11:40:42 pm »

Hello, so we've encountered some problems when we try to draw a vector that contains sf::Text objects in it. We have a class that makes the objects, a for loop that puts them into the vector, and a while loop that should theoretically draw them - but that doesn't happen. The compiler also doesn't fling any kind of error at us, so we are not entirely sure what the issue is. Entire source code here -

#include <SFML/Graphics.hpp>
#include <vector>
#include <iostream>
#include <string>
using namespace std;

class texts{
    public:
    sf::Text textClass;
    texts();
    texts(sf::Font font, string symbol, int characterSize, float e, float f){
        textClass.setFont(font);
        textClass.setString(symbol);
        textClass.setCharacterSize(characterSize);
        textClass.setColor(sf::Color::Red);
        textClass.setStyle(sf::Text::Bold);
        textClass.setPosition(e, f);
    }
    unsigned int charSize(){
        return textClass.getCharacterSize();
    }
    string returnString(){
        return textClass.getString();
    }
};


int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "Project Talon!");

    sf::Font font;
    if (!font.loadFromFile("OpenSans-Bold.ttf"))

    // error...

            RLmap[i][j] = 1;

            }
        }

        text.setPosition(x,y);

                        {
                            x = x+24;
                        }
                }

        }
               
        window.clear();
        window.draw(text);

        while(!allTexts.empty()){
                window.draw(allTexts.back().textClass);
                allTexts.pop_back();

We're trying to make a roguelike and figured that we would start with making a few basic walls and an @ symbol to move around as the player. We are using sf::Text objects for all of this business, but if there is a more preferable method of doing this, we would love to hear it. Thank you for any help that you can offer on this issue!
