minim: 1st clip doesn't play on 1st play()

pop451

In my simple picture dictionary code cited below, I add the last line in setup() [line 29], i.e. preload the 1st sound clip, or else it doesn't play on 1st instance of play().

I guess this is not the best solution. Any advice?

import ddf.minim.spi.*;
import ddf.minim.signals.*;
import ddf.minim.*;
import ddf.minim.analysis.*;
import ddf.minim.ugens.*;
import ddf.minim.effects.*;
Minim minim;
AudioPlayer player;

PImage image, imageSprite;
int sX, sY, eX, eY ;
XML fruitList ;
XML[] fruits ;
int click;
String name, thisPage, startMessage;

void setup() {
  size(600, 400) ;
  minim = new Minim(this);
  click = 0 ;
  name ="";
  thisPage = "";

  image = loadImage("fruits.jpg") ;
  fruitList = loadXML("fruitList.xml") ;
  fruits = fruitList.getChildren("fruit") ;
  startMessage = "In this lesson, you will learn " + fruits.length + " words.\nLeft-click to start & go next. \nRight-click to go back." ;

  player = minim.loadFile("0.mp3", 2048); // to preload the initial sound clip
}

void draw() {
  if (click == 0) {
    background(255) ;
    textSize(20);
    fill(0);
    text(startMessage, width/2 - textWidth(startMessage)/2, height/2 - 40);
  } else {
    background(255) ;
    name = fruits[click-1].getChild("name").getContent();
    fill(0);
    textSize(40);
    text(name, width/2 - textWidth(name)/2, 60);


    sX = int(fruits[click-1].getChild("get/sX").getContent());
    sY = int(fruits[click-1].getChild("get/sY").getContent());
    eX = int(fruits[click-1].getChild("get/eX").getContent());
    eY = int(fruits[click-1].getChild("get/eY").getContent());
    imageSprite = image.get(sX, sY, eX - sX, eY - sY);
    image(imageSprite, width/2 - imageSprite.width/2, height/2 - imageSprite.height/2) ;

    thisPage = click + "/" + fruits.length ;
    fill(127);
    textSize(20);
    text(thisPage, width - textWidth(thisPage), height -25);
  }
}

void mouseClicked () {
  if (mouseButton == LEFT) {
    click++ ;
  } else if (mouseButton == RIGHT) {
    click-- ;
  }
  click = constrain(click, 1, fruits.length);

  player = minim.loadFile(click-1 + ".mp3", 2048); // 1024, 2048
  player.setGain(-20);
  player.play();
}

Without line 29, your mouseClicked() has no effect?

Dear kfrajer,

Not quite.

Say, I comment out line 29...

When I run the program & give the 1st left click, mouseClicked() makes the value of "click" to 1, so at line 68+ "0.mp3" should be loaded & played, but there is no sound.

Then, when I give another click (the value of "click" is now 2), "1.mp3" is played alright

Then, when I give a right click to revert the value of "click" to 1, "0.mp3" IS played.

I can reproduce it as I don't have the files. Something that could make a difference. At line 68:

player = minim.loadFile( (click-1) + ".mp3", 2048);

Not sure if it will make a difference. Give it a try.

I also tested it with this small change in your last function:

void mouseClicked () {
  if ( player!=null && player.isPlaying())
    player.pause();

  if (mouseButton == LEFT) {
    click++ ;
  } else if (mouseButton == RIGHT) {
    click-- ;
  }
  click = constrain(click, 1, fruits.length);

  player = minim.loadFile("snd0"+ (click-1) + ".mp3", 2048); // 1024, 2048
  //player.setGain(-20);
  player.play();
}

You can enable the setGain() line. I tested it and it works.

Thanks for your suggestion, kfrajer. I tried it, but the result is the same.

I've realized that my PC's power option was set to "eco", so I tried changing it to "high performance", and then it works.

With the "eco" mode (or on low performance PCs), the preloading at line 29 still seems to be a way of workaround.
