sf::Text 不显示？

Question

I'm trying to display a sf::Text on my window and it doesn't work and i don't understand why !

Here's an example of the code: constructor

timerText.setFont(getFont());
timerText.setString("test");
timerText.setCharacterSize(70);
timerText.setColor(Color::Red);

getFont() :

Font& Timer::getFont(){
Font font;
if(!font.loadFromFile("arial.ttf")){
    cout << "font not loaded" << endl;
}
return font;

}

draw() :

timerText.setPosition(Vector2f(center.x - 8, center.y - size.y/2 + 12));
window.draw(timerText);

All my other draws work perfectly and i haven't error when i'm loading the font. Sorry for my English and thank you for your help !

Answer 1

Resolved by adding a private variable sf::Font in my class and by swaping setFont(getFont()); by font.loadFromFile(fontFile); setFont(font);

I still doesn't understand my error but now it works.

Answer 2

at getFont() , you load a font into local variable in stack memory. When the function returns, it is deleted automatically..

You should move or allocate it other place..

Font font;
Font& Timer::getFont(){
    if(!font.loadFromFile("arial.ttf")){
        cout << "font not loaded" << endl;
    }
    return font;
}
