Playing sounds simultaneously

[seba174]

Hi,
i have a problem when trying to play few sounds simultaneously.

I am currently using this method:
SoundManager.h

(click to show/hide)

#pragma once
#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <vector>
#include <map>

enum SoundsNames {Explosion};

class SoundManager
{
        std::vector<sf::Sound> sounds;
        std::map<SoundsNames, sf::SoundBuffer> soundBuffers;

        float soundsVolume;

public:
        SoundManager();

        void playSound(SoundsNames soundName);
};
 

SoundManager.cpp

(click to show/hide)

#include "SoundManager.h"

SoundManager::SoundManager()
{
        soundBuffers[SoundsNames::Explosion].loadFromFile("Sounds/Explosion.wav");
        soundsVolume = 100;
}

void SoundManager::playSound(SoundsNames soundName)
{
        sounds.push_back(sf::Sound(soundBuffers[soundName]));
        sounds[sounds.size() - 1].setVolume(soundsVolume);
        sounds[sounds.size() - 1].play();
}

 

When i use playSound() function after Player does specific action, it plays sound properly. But the problem is, that when i use playSound() and then after a short time (when the sound hasn't finished yet) use it again, the new sound of course starts, but that one which hasn't finished yet can't be heard (it just stops).
Is there any method to solve this?

Thanks in advance for all replies.

It could be the vector resizing as that would cause it to have to move the elements to a place that would fit them all. When an sf::Sound is moved, it is stopped.

A couple of solutions to this are: 'pre-size' the vector to a size that would cover however many sounds might be playing at once (pre-size here means to resize or reserve the vector), or use an std::list or std::forward_list instead of a vector.

Yeah, you are right. I changed std::vector for std::list, and that did the trick. Now everything works as intended.
Thanks a lot for help.
