Sound only plays once, why?

Leupsi

Hi community!
I've writen some code but i don't know how to get it working properly. I want to make a sound play and scaling the shape to the sound when the mouse moves over a certain area (rectangle or other shape). The sound works, but only once. After the sound has played i'm not able to replay it. And i've on more question. How can i scale a triangle, is there a CENTER mode like for rects? Cause my code only works with Java i've attached a short video as well as the original code. Thank's! :)

    {
      Snare.play();
    }
    if (mouseX > 225 && mouseX < 275 && mouseY > 100 && mouseY < 150)
    {
      Bass.play();
    }
    if (mouseX > 356 && mouseX < 411 && mouseY > 101.5 && mouseY < 149)
    {
      Cymbal_Crash.play();
    }

}

call rewind() before play(). the playhead needs to be pushed back to the start after you played it. rewind does this.

DCRaven

and you can use sound.trigger() or you could when I last checked

Leupsi

@mschi: The problem with rewind() ist that the sound keeps playing and overlays endless times so you only get to hear a mess. I would like to get the sound playing always one time when you move above the shape. Any ideas? :)
And trigger() does not seem to work anymore?

mschi

try pause(); rewind(); play();

maybe just calling play(0); also does the job.

Unfortounately this doesn't change anything. ^^
I really don't know what's wrong here, that's the actual code:

import ddf.minim.*;

Minim minim;
AudioPlayer Snare, Bass, Cymbal_Crash;


void setup()
{
  size(500, 250);

  minim = new Minim(this);
  Snare = minim.loadFile("Snare_Hit.wav");
  Bass = minim.loadFile("Bass_Drum.wav");
  Cymbal_Crash = minim.loadFile("Cymbal_Crash.wav");

}

void draw()
{
  background(255);

  ellipse(120.5, 125, 47, 47);
  rect(250, 125, 47, 47);


  //Snare_Hit = Circle
  noFill();
  float mix1 = Snare.mix.level();
  println(mix1);
  float grau1 = map(mix1, 0, 0.5, 0, 255);

  stroke(grau1);
  ellipse(120.5, 125, mix1*200, mix1*200);


  //Bass_Drum = Rect
  noFill();
  float mix2 = Bass.mix.level();
  println(mix2);
  float grau2 = map(mix2, 0, 0.5, 0, 255);

  stroke(grau2);
  rectMode(CENTER);
  rect(250, 125, mix2*200, mix2*200);


  //Cymbal_Crash = Triangle
  noFill();
  float mix3 = Cymbal_Crash.mix.level();
  println(mix3);
  float grau3 = map(mix3, 0, 0.5, 0, 255);

  stroke(grau3);
  triangle(356.866, 148, 383.135, 102.5, 409.405, 148);



    if (mouseX > 97+8 && mouseX < 144+8 && mouseY > 101.5+8 && mouseY < 148.5+8)
    {
      Snare.pause();
      Snare.rewind();
      Snare.play();
    }

    if (mouseX > 225 && mouseX < 275 && mouseY > 100 && mouseY < 150)
    {
      Bass.pause();
      Bass.rewind();
      Bass.play();
    }

    if (mouseX > 356 && mouseX < 411 && mouseY > 101.5 && mouseY < 149)
    {
      Cymbal_Crash.pause();
      Cymbal_Crash.rewind();
      Cymbal_Crash.play();
     }

}

And that's a short demonstration of the repetitive sound:

In setup just add player.loop();

mschi

take your play trigger code out of draw() and insert it into a mousePressed function:

void mousePressed() {
    if (mouseX > 97+8 && mouseX < 144+8 && mouseY > 101.5+8 && mouseY < 148.5+8)
    {
      Snare.pause();
      Snare.rewind();
      Snare.play();
    }

    if (mouseX > 225 && mouseX < 275 && mouseY > 100 && mouseY < 150)
    {
      Bass.pause();
      Bass.rewind();
      Bass.play();
    }

    if (mouseX > 356 && mouseX < 411 && mouseY > 101.5 && mouseY < 149)
    {
      Cymbal_Crash.pause();
      Cymbal_Crash.rewind();
      Cymbal_Crash.play();
     }
}

@mschi: Wow, that's really cool and does the job for me, thank you very much! :)
Do you also know how to scale a triangle with it's ankerpoint centered? ^^

mschi

you basically have to do something like that:

draw(){
pushMatrix();
  // define position where circle is supposed to sit
  translate(50, 50);

  // big is a boolean that is true as long as the circle is supposed to be big
  // you have to set it to true/false at some place
  if(big)scale(2.0);
  else scale(1.0);

  ellipseMode(CENTER);
  ellipse(0, 0, 40,40);
popMatrix();

pushMatrix();
... do the same with rect
popMatrix();

pushMatrix();
... do the same with triangle
popMatrix();
}

yes .trigger works and it would be way easier. This is a processing example that I changed a little:

import ddf.minim.*;

Minim minim;
AudioSample kick;
AudioSample snare;

void setup() {
  size(512, 200, P3D);
  minim = new Minim(this);
  kick = minim.loadSample( "kick.mp3", 512);
  snare = minim.loadSample("snare.mp3", 512);
}

void draw() {
  background(0);
  stroke(255);
  for (int i = 0; i < kick.bufferSize() - 1; i++) {
    float x1 = map(i, 0, kick.bufferSize(), 0, width);
    float x2 = map(i+1, 0, kick.bufferSize(), 0, width);
    line(x1, 50 - kick.mix.get(i)*50, x2, 50 - kick.mix.get(i+1)*50);
    line(x1, 150 - snare.mix.get(i)*50, x2, 150 - snare.mix.get(i+1)*50);
  }
}

void mousePressed() {
  if (mouseX < width/2) snare.trigger();
  if (mouseY > width/2) kick.trigger();
}

Hello, I think I know what the mousePressed is suppose to do but it is being used with width instead of height which does not seem to have the proper effect. I changed it to this and it seems to work better. Cool little mini drum pad BTW. DJ xSUBn ({-_-})

void mousePressed() {
  if (mouseY < height/2) { snare.trigger(); } else { kick.trigger(); }
}
