Trouble with sf::Text
« on: June 01, 2012, 06:39:07 pm »
Hello,
I'm having trouble with the sf::Text class.  Here is part of my code:

// gui.cpp

playerCardGUI::playerCardGUI()
{
    texture.loadFromFile("data\\GUI\\playercard.png");
    texture.setSmooth(false);
    sprite.setTexture(texture);
}

playerCardGUI::~playerCardGUI()
{
}

void playerCardGUI::create(unsigned short int argOwner, NATIONALITY natl, sf::Vector2f pos)
{
    texture.loadFromFile("data\\GUI\\playercard.png");
    texture.setSmooth(false);
    sprite.setTexture(texture);

    playerName.setFont(data.mainFont);
    health.setFont(data.mainFont);
    ammoMag.setFont(data.mainFont);
    ammoTotal.setFont(data.mainFont);

    playerName.setString("Name");

    owner = argOwner;

    if(natl == US)
        txNational.loadFromFile("data\\GUI\\ally_US.png");
    else if(natl == GR)
        txNational.loadFromFile("data\\GUI\\axis_GR.png");

    sprite.setPosition(pos);
    playerName.setPosition(pos);
}

void playerCardGUI::update(int HP, int ammo, int totalAmmo)
{
    std::stringstream stream;

    stream << HP;
    health.setString(stream.str());

    stream.clear();
    stream << ammo;
    ammoMag.setString(stream.str());

    stream.clear();
    stream << totalAmmo;
    ammoTotal.setString(stream.str());
}

void playerCardGUI::draw()
{
}
// gui.h
#ifndef GUI_H
#define GUI_H

class playerCardGUI
{
    private:
        // graphics variables
        sf::Sprite sprite;
        sf::Texture texture;
        sf::Sprite spClass, spNational;
        sf::Texture txClass, txNational;

        // text variables
        sf::Text playerName;
        sf::Text health;
        sf::Text ammoMag, ammoTotal;

        // misc variables
        unsigned short int owner;
    public:
        playerCardGUI();
        ~playerCardGUI();
        void create(unsigned short int argOwner, NATIONALITY natl, sf::Vector2f pos);

        void update(int HP, int ammo, int totalAmmo);
        void draw();

    friend class Player;
};

#endif // GUI_H

Specifically, the issue is with playerName.  When I try to compile this, it works fine-- until I close the main program window.  Then the process continues to run until I manually end it using the Windows Task Manager.

I don't see anything wrong with my code.  Does anyone else see anything wrong?
Thanks in advance.

The famous AMD/ATI bug strikes again!  ;D

You should avoid the default sf::Text constructor.
The solution I found is creating a temporary sf::Text object inside my draw method:

sf::Text playerName (p1Name, data.mainFont, 30);
...
window.draw (playerName);

Isn't that a lot slower? Having to reallocate a Text object and recalculate the text geometry every frame?

Thanks, mateandmetal.  ;D
I'll probably just add something like
playerName = new sf::Text(p1Name, data.mainFont, 30);
in the constructor.

Does anyone know if Laurent will fix this bug before the official SFML 2 release?  It seems like it will get pretty annoying.  :(

Please don't use new unless really necessary. Why can't the sf::Text be an automatic variable?

The bug is quite complex to fix and potentially requires an internal redesign, so I doubt it will be fixed for version 2.0. The workaround is to link statically.

Without the new, the process continues to run after I close the program window.
