SFML Drawing centered text

I'm trying to center some text in SFML. It doesen't really work though as you can see in the picture below. enter image description here

Maybe something is wrong with my math?

void TextRenderer::renderCentered(sf::RenderWindow& window, std::string string, sf::Vector2f     position, int size, sf::Color color) {
    sf::Text text;

    text.setFont(TextRenderer::kavoon);
    text.setString(string);

    float width = text.getLocalBounds().width;

    text.setPosition(position.x - width / 2, position.y);

    text.setCharacterSize(size);
    text.setColor(color);

    window.draw(text);
}

in render method:

TextRenderer::renderCentered(*window, pickuptext.str(), sf::Vector2f(player->sprite.getPosition().x, player->sprite.getPosition().y - 48), 28, sf::Color(255, 145, 61));
TextRenderer::renderCentered(*window, pickuptextdesc.str(), sf::Vector2f(player->sprite.getPosition().x, player->sprite.getPosition().y - 16), 18, sf::Color(255, 145, 61));
Solution

  • The formula for centering text horizontally within a bounding box is:

    text_start = bounding_box_width / 2 - text_width / 2;

    Looks like you may not be supplying the bounding box horizontal center point.
