ОК, я не знаю, как сформулировать этот вопрос, но, возможно, мой код разобьет проблему:
public class ControllerTest
{
public static void main(String [] args)
{
GamePadController rockbandDrum = new GamePadController();
DrumMachine drum = new DrumMachine();
while(true)
{
try{
rockbandDrum.poll();
if(rockbandDrum.isButtonPressed(1)) //BLUE PAD HhiHat)
{
drum.playSound("hiHat.wav");
Thread.sleep(50);
}
if(rockbandDrum.isButtonPressed(2)) //GREEN PAD (Crash)
{
//Todo: Change to Crash
drum.playSound("hiHat.wav");
Thread.sleep(50);
}
//Etc....
}
}
}
public class DrumMachine
{
InputStream soundPlayer = null;
AudioStream audio = null;
static boolean running = true;
public void playSound(String soundFile)
{
//Tak a sound file as a paramater and then
//play that sound file
try{
soundPlayer = new FileInputStream(soundFile);
audio = new AudioStream(soundPlayer);
}
catch(FileNotFoundException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
AudioPlayer.player.start(audio);
}
//Etc... Methods for multiple audio clip playing
}
Теперь проблема в том, если я уменьшу задержку в
Thread.sleep(50)
тогда звук воспроизводится несколько раз в секунду, но если я останусь на этом уровне или выше, я могу пропустить воспроизводимые звуки ...
Это странная проблема: когда задержка слишком мала, звук зацикливается. Но если он слишком высокий, он пропускает звуки. Это просто проблема, когда мне нужно настроить параметры, или есть другой способ опроса контроллера без зацикливания звука?
Изменить: Если мне нужно опубликовать код для опроса контроллера, я буду ...
