Hello there,
I have myself a SoundLoader class which loads some wav files into a map of soundbuffers and then I can call a method called PlaySound which takes an enum to play the sound, here is my method
if (playingSounds.size() == 0)
{
playingSounds.push_back(sf::Sound());
playingSounds.at(0).setBuffer(Sounds[soundName]);
playingSounds.at(0).play();
}
else
{
int location = -1;
for (int i = 0; i < playingSounds.size(); i++)
{
if (!playingSounds.at(i).getStatus() == sf::Sound::Playing)
{
location = i;
}
if (location != -1)
{
break;
}
}
if (location != -1)
{
playingSounds.at(location).setBuffer(Sounds[soundName]);
playingSounds.at(location).play();
}
else
{
playingSounds.push_back(sf::Sound());
playingSounds.at(playingSounds.size()-1).setBuffer(Sounds[soundName]);
playingSounds.at(playingSounds.size() - 1).play();
}
}
However I was testing my game and for a minute or so it is all going fine, but then all of a sudden I got this error
An internal OpenAL call failed in SoundSource.cpp (181) : AL_INVALID_NAME, an unacceptable name has been specified
What am I doing to cause this? P.S. my soundloader only has 60 lines of code so not sure what the 181 is relating to
UPDATE
I have just coded my enemy to spam its firing which plays one sound, this worked for a few seconds then an error was shown and my game continued for about 3 seconds then I got this error in visual studio
Unhandled exception at 0x56455365 (sfml-system-d-2.dll) in SpaceDestroyer.exe: 0xC00000FD: Stack overflow (parameters: 0x00000001, 0x07B52FFC).
then it shows in Err.cpp
virtual int overflow(int character)
{
if ((character != EOF) && (pptr() != epptr()))
{
// Valid character
return sputc(static_cast<char>(character));
}
else if (character != EOF)
{
// Not enough space in the buffer: synchronize output and try again
sync();
return overflow(character);
}
else
{
// Invalid character: synchronize output
return sync();
}
}
sfml-system-d-2.dll!`anonymous namespace'::DefaultErrStreamBuf::overflow(int character) Line 61 C++
UPDATE
It's ok I found it, I just changed my line to check location to be this
if (playingSounds.at(i).getStatus() != sf::Sound::Playing && location == -1)
{
location = i;
}
but just to let everyone else know, make sure when you are playing sounds never reach more than 140 sounds in memory, this will throw the "Internal OpenAL error", this error happened to me when my playingSounds.size() was equal to 140
