Audio / Sound not playing, debugging says no symbols loaded for sfml-audio-d-2.dll
« on: June 25, 2013, 03:18:42 pm »
Hello everybody,
Today I decided to re-write the design/logic in my Sound class (renamed to Audio) (it used to work before the re-write but the design was bad) by storing a std::string and a sf::SoundBuffer in a std::map in the class and then loading all .wav files into this map on start-up of the application (later on moving this to a separate thread, of course). A new issue had arisen so I started throwing around breakpoints and came to the conclusion that it for whatever reason seems to not ever load the sfml-audio-d-2.dll, even though it is in place with all other .dll's. Here a screenshot of the error:
(take a look at the Watch window)
Showing that it did in fact find the song we are trying to play (different sound being played):
As for the .dll's:
Now as for the code, it can all be found on this GitHub repository, but I'll paste some code regarding the issue here anyhow.
audio.h
audio.cpp
Loading the audio (done using the Dirent library to load all files from a given directory)
Playing the audio (example)
Hope that is enough!
Thanks for reading,
Jasper

if ((dir = opendir("Audio")) != NULL)
{
while ((ent = readdir(dir)) != NULL)
{
if (ent->d_name[0] != '.') //! These seem to be the only hidden invisible files in there and the dirent library doesn't offer detection for it, so this will work. :)
{
ss << "Audio/" << ent->d_name;
audio->Load(ss.str().c_str());
ss.str(std::string());
}
}
closedir(dir);
}
}
{
DIR* dir;
struct dirent* ent;
std::stringstream ss;
audio = new Audio(this);
if ((dir = opendir("Audio")) != NULL)
{
while ((ent = readdir(dir)) != NULL)
{
if (ent->d_name[0] != '.') //! These seem to be the only hidden invisible files in there and the dirent library doesn't offer detection for it, so this will work. :)
{
ss << "Audio/" << ent->d_name;
audio->Load(ss.str().c_str());
ss.str(std::string());
}
}
closedir(dir);
}
}
Playing the audio (example)
Menu::Menu(Game* _game)
{
game = _game;
selectedOption = 1;
currentMenu = MENU_MAIN;
newMenu = MENU_NONE;
movingCurrMenuOut = false;
movingNewMenuIn = false;
game->GetAudio()->Play("Audio/menu_music.wav", true);
}
{
game = _game;
selectedOption = 1;
currentMenu = MENU_MAIN;
newMenu = MENU_NONE;
movingCurrMenuOut = false;
movingNewMenuIn = false;
game->GetAudio()->Play("Audio/menu_music.wav", true);
}
Hope that is enough!
