Graphics / One sprite, various objects, am I doing it wrong?

« on: November 08, 2009, 05:57:52 pm »

I am new to SFML and I'm making a small shmup. I have this image of a star(its actually a white dot but whatever). Then  Ive to draw each of the 1000 stars in the screen. But instead of using one sprite for each star I use sprite for every star! And I'm not sure if this is the right way

Code: [Select]


    for(int i = 0; i < (int)cg->stars.size(); i++)
    {
        switch(cg->stars[i].kind)
        {
            case 0:
            {
                cg->sprites[sid_star0].SetPosition(cg->stars[i].x, cg->stars[i].y);
                cg->sprites[sid_star0].SetRotation(cg->stars[i].rot);

                wnd.Draw(cg->sprites[sid_star0]);
            }
            case 1:
            {
                cg->sprites[sid_star1].SetPosition(cg->stars[i].x, cg->stars[i].y);
                cg->sprites[sid_star1].SetRotation(cg->stars[i].rot);

                wnd.Draw(cg->sprites[sid_star1]);
            }
        }
    }

Graphics / Font segfault D:

« on: November 08, 2009, 02:04:49 am »

Hello, I added this code to my game

Code: [Select]

void draw_hud(){
    sf::String score, hp;
    std::stringstream ss;

    score.SetFont(cg->hud_font);
    hp.SetFont(cg->hud_font);

    ss << (int)cg->player.score;
    score.SetText(ss.str().c_str());

    ss.str("");
    ss << "%" << cg->player.hp;
    hp.SetText(ss.str().c_str());

    score.SetPosition(24,480-48);
    wnd.Draw(score);

    hp.SetPosition(400, 480-48);
    wnd.Draw(hp);
}

And now a segfault happens when I close the game D:
Call stack:
#0 08FEAFDA   igldev32!devProcessAttach() (C:\WINDOWS\system32\igldev32.dll:??)

I already checked, its that code that makes segfault happen.
