C++ (Cpp) pollMusic Examples

Example #1

File: adlibmusic.cpp Project: AdamRi/scummvm-pink

int AdLibMusic::readBuffer(int16 *data, const int numSamples) {
	if (_musicData == NULL) {
		// no music loaded
		memset(data, 0, numSamples * sizeof(int16));
	} else if ((_currentMusic == 0) || (_numberOfChannels == 0)) {
		// music loaded but not played as of yet
		memset(data, 0, numSamples * sizeof(int16));
		// poll anyways as pollMusic() can activate the music
		pollMusic();
		_nextMusicPoll = _sampleRate / 50;
	} else {
		uint32 render;
		uint remaining = numSamples;
		while (remaining) {
			render = (remaining > _nextMusicPoll) ? _nextMusicPoll : remaining;
			remaining -= render;
			_nextMusicPoll -= render;
			YM3812UpdateOne(_opl, data, render);
			data += render;
			if (_nextMusicPoll == 0) {
				pollMusic();
				_nextMusicPoll = _sampleRate / 50;
			}
		}
	}
	return numSamples;
}

Example #2

File: gmmusic.cpp Project: iPodLinux-Community/iScummVM

void GmMusic::timerCall(void) {
	_timerCount += _midiDrv->getBaseTempo();
	if (_timerCount > (1000000 / 50)) {
		// call pollMusic() 50 times per second
		_timerCount -= 1000000 / 50;
		if (_musicData != NULL)
			pollMusic();
	}
}

Example #3

File: music.cpp Project: olofn/db_public

	if (playingFile == file) {

	}

	if (playing != NULL) {

	}

	player = al_start_duh(playing, 2, 0, volume, 4096, 44100);
