Title: Sound who doens't play.
Post by: Lolilolight on April 02, 2015, 07:46:49 pm

Hi!

I'm trying to play a sound but it doesn't play :

int main() {
    sf::SoundBuffer buffer;
    buffer.loadFromFile ("sounds/ballhurtbar.wav");
    sf::Sound sound;
    sound.setBuffer(buffer);
    sound.play();
    return 0;
}
 

OS : ubuntu LTS 64 bits.
SFML version : 2.2.

Lolilolight you make me sick, you have been around how long now? 5+ years and you have 1.2k+ posts to your name. And you really can't even find such a simple mistake in your code? Or even try the examples from the tutorials? Or for that matter just look around the forums a little bit...

The most common mistake is to let a sound buffer go out of scope (and therefore be destroyed) while a sound still uses it.

The same applies to sounds in general and not just buffers.

(BTW, thank you for at least not posting a wall of code)

And just for the record...

int main() {
    sf::SoundBuffer buffer;
    buffer.loadFromFile ("sounds/ballhurtbar.wav");
    sf::Sound sound;
    sound.setBuffer(buffer);
    sound.play(); // this is non blocking
    return 0;
} // everything goes byebye

And just to make sure that this thread does not end up going on forever, here's another spoiler with a complete working example (including build instructions).
Now there should be no reason at all to continue this thread.

(click to show/hide)

#include <SFML/System.hpp>
#include <SFML/Audio.hpp>

int main() {
    sf::SoundBuffer buffer;
    buffer.loadFromFile("sounds/ballhurtbar.wav");
    sf::Sound sound;
    sound.setBuffer(buffer);
    sound.play();
    const auto delay = sf::milliseconds(1);
    do {
        sf::sleep(delay);
    } while(sound.getStatus() == sf::SoundSource::Playing);
}
 

$ g++ -std=c++11 -o play -lsfml-audio -lsfml-system play.cc
$ ./play

Arg right this is non blocking, sorry sorry.
