Sound Code in void draw makes me problem

TheKillerHD · September 14, 2018, 6:12pm

I want the sound to be played when the ball touches the player. At the moment I have the sound in void draw and that makes me problems because messages appear in the console and then the game blocks.
Can I somehow write it in void setup so that the sound plays when the player touches the ball?

void draw(){
  background(bg);
  rect(spieler_x, spieler_y, 20, 100);
  rect(ball_x, ball_y, 10 ,10);
  
  //Blur-Effekt
  for(int i = (blur_anzahl - 1); i > 0; i--){
    fill(255, 0, 0, 255/(i*2));
    positions_array[i][0] = positions_array[i-1][0];
    positions_array[i][1] = positions_array[i-1][1];
    rect(positions_array[i][0], positions_array[i][1], 10 ,10);
  }
  positions_array[0][0] = ball_x;
  positions_array[0][1] = ball_y;
  fill(200, 0, 0, 255);
 
  
  if(keyPressed){
    if(keyCode == DOWN){
      if(spieler_y < 650){
        spieler_y = spieler_y + 5;
      }
    }
    if(keyCode == UP){
      if(spieler_y > 50){  
        spieler_y = spieler_y - 5;
      }
    }
  }
  ball_x = ball_x + ball_geschwindigkeit_x;
  ball_y = ball_y + ball_geschwindigkeit_y;
  
  if(ball_x < 30){
    if(ball_y < (spieler_y + 55) && ball_y > (spieler_y - 55)){
      file = new SoundFile(this, "plop.mp3");    //Sound
      file.play();
      ball_geschwindigkeit_x = (-ball_geschwindigkeit_x) + 1;
      ball_geschwindigkeit_y = ball_geschwindigkeit_y - (spieler_y - ball_y) * 0.1;
      runde = runde + 1;
    }else{
       file = new SoundFile(this, "game_over.mp3");    //Sound
       file.play();

Hi TheKillerHD,

Please avoid posting picture of your code.

Instead copy/paste your code here, select it and hit the code format button </>

Thanks

TheKillerHD · September 14, 2018, 7:06pm

Okay I changed it now. But can you help me with this problem?

jb4x · September 14, 2018, 7:09pm

You want to load your sound in the setup() function: that’s made for it.

What you are currently doing right now is loading your song over and over every time you want to play it.

Instead create a global variable, load it in setup and play it when needed.

TheKillerHD · September 14, 2018, 7:25pm

I don’t understand how I can do this. Can you give me pls an example how I can do it? I have reuploaded my post with the command because I have forgot that I have two sounds.

jb4x · September 14, 2018, 7:35pm

You can open the following example in processing:

ProcSoundEx

It will give you an idea on how it works.

Then you can replace the example code with the following:

import processing.sound.*;

SoundFile soundfile;

void setup() {
  size(640, 360);
  background(255);

  //Load a soundfile
  soundfile = new SoundFile(this, "vibraphon.aiff");
}

void draw() {
}


void mousePressed() {
  if (soundfile.isPlaying() == 1) {
    soundfile.stop();
  } else {
    soundfile.play();
  }
}

What it will do is play and stop the sound alternatively every time you hit the mouse.

TheKillerHD · September 14, 2018, 7:41pm

And how can I do this with two sounds?

jb4x · September 14, 2018, 7:43pm

Just declare 2 variables like you would do for any other kind of variables:

import processing.sound.*;

SoundFile soundfile1;
SoundFile soundfile2;

void setup() {
  ...
  soundfile1 = new SoundFile(this, "file1.aiff");
  soundfile2 = new SoundFile(this, "file2.aiff");
}

TheKillerHD · September 14, 2018, 7:56pm

Now the game don’t block, but I became the same message in the console and I don’t know how I can’t put the soundfile1.play(); and the soundfile2.play(); in the void draw.

void setup(){
  positions_array = new float [blur_anzahl][2];
  spieler_x = 20;
  spieler_y = 353;
  ball_x = 450;
  ball_y = 350;
  ball_geschwindigkeit_x = - 4;
  ball_geschwindigkeit_y = 0;
  runde = 0;
  size (900, 700);
  rectMode(CENTER);
  bg = loadImage("pong_bg.png");    //Hintergrundbild
  noStroke();
  schrift = loadFont("burbank30.vlw");
  textFont(schrift);
  
  //Sound
  soundfile1 = new SoundFile(this, "plop.mp3");
  soundfile2 = new SoundFile(this, "game_over.mp3");
}

void draw(){
  background(bg);
  rect(spieler_x, spieler_y, 20, 100);
  rect(ball_x, ball_y, 10 ,10);
  
  //Blur-Effekt
  for(int i = (blur_anzahl - 1); i > 0; i--){
    fill(255, 0, 0, 255/(i*2));
    positions_array[i][0] = positions_array[i-1][0];
    positions_array[i][1] = positions_array[i-1][1];
    rect(positions_array[i][0], positions_array[i][1], 10 ,10);
  }
  positions_array[0][0] = ball_x;
  positions_array[0][1] = ball_y;
  fill(200, 0, 0, 255);
 
  
  if(keyPressed){
    if(keyCode == DOWN){
      if(spieler_y < 650){
        spieler_y = spieler_y + 5;
      }
    }
    if(keyCode == UP){
      if(spieler_y > 50){  
        spieler_y = spieler_y - 5;
      }
    }
  }
  ball_x = ball_x + ball_geschwindigkeit_x;
  ball_y = ball_y + ball_geschwindigkeit_y;
  
  //This is when then ball touches the player
  if(ball_x < 30){
    if(ball_y < (spieler_y + 55) && ball_y > (spieler_y - 55)){
      soundfile1.play();    //Sound
      ball_geschwindigkeit_x = (-ball_geschwindigkeit_x) + 1;
      ball_geschwindigkeit_y = ball_geschwindigkeit_y - (spieler_y - ball_y) * 0.1;
      runde = runde + 1;
    }else{
       soundfile2.play();    //Sound
       ball_x = 450;
       ball_y = 350;
       ball_geschwindigkeit_x = - 4;
       ball_geschwindigkeit_y = 0;
       runde = 0;
       spieler_y = 353;

jb4x · September 14, 2018, 7:59pm

Can you tell us what is the error message?

TheKillerHD · September 14, 2018, 8:00pm

This is the message: Sep 14, 2018 9:50:38 PM com.jsyn.devices.javasound.JavaSoundAudioDevice

Is there still a problem with the Processing Sound library? If so, I would recommend using the old minim library. Should work well

TheKillerHD · September 15, 2018, 9:13am

Okay I try, let’s hope it works.

TheKillerHD · September 15, 2018, 9:20am

Minim doesn’t work because I haven’t the old processing verison. I have the 3.4 processing version and that’s the problem why I can’t use the minim library.

The message in the console comes now only if I click on the playbutton.

jb4x · September 15, 2018, 10:25am

Maybe @kevinstadler can help, he is updating the sound library.

kevinstadler · September 16, 2018, 4:50am

@TheKillerHD

This is not an error message, just information about the sound library loading, you can ignore it (I’ll try to suppress the message in later versions of the library).

Is there actually anything that’s not working about the sound playback, except for the fact that it prints this message?

kevinstadler · September 16, 2018, 4:52am

@jb4x people repeatedly loading the same sound file in draw() shouldn’t actually be a problem, the new Sound library first checks if it has already loaded a file from the same path and simply reuses the same one from memory!

jb4x · September 16, 2018, 5:39am

Hoo, I didn’t know about that one! Thanks for clarifying

Still, I prefer to load everything once for clarity in the code.

What is strange is that doing so apparently changed the behavior of his sketch:

TheKillerHD · September 16, 2018, 8:23am

No, everything works and I’m very grateful that you helped me so well with the problem.
