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?

```auto
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 🙂

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

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.

</div>

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.

</div>

You can open the following example in processing:

![ProcSoundEx](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/1/199878f19ecf37d7ed85dd84dbb4bb9ae5bd2053.png)

It will give you an idea on how it works.

Then you can replace the example code with the following:

```auto
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.

And how can I do this with two sounds?

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

```auto
import processing.sound.*;

SoundFile soundfile1;
SoundFile soundfile2;

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

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.

      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

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

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.**

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?

@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!

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:
