What to do? (ArrayIndexOutOfBoundsExceptation)

Vasco

For now i'm only trying to do some keyPressed to change music. But this is showing me an error, that i dont kow how tot fix it. Error name is "ArrayIndexOutOfBoundsExceptation:1".

all arrays in processing start with the index 0

so 1st entry = 0

so 2nd entry = 1

I fixed lines 12 and 13 above

the error

the error is shown because in line 13 you had 2 which was higher than the maximum value of the array

Vasco

Kk. Thank you for the help

Chrisir

also line 29

i've been changing my code, i've made some attempts for what i want now, but i fail in all. This is my last save before i do my tests.

import java.io.File;
import ddf.minim.*;
import ddf.minim.analysis.*;

//BIBLIOTECA MUSICA

Minim minim;
AudioPlayer[] som = new AudioPlayer[5]; //NUMERO TOTAL DE MUSICAS
AudioMetaData meta;

PImage outline, play, pause; // IMAGEM COMANDO

FFT fft;

void setup() 
{ 
  size(1280, 720); //TAMANHO DA JANELA

  minim = new Minim(this);

  som[0]=minim.loadFile("C:/Users/Vasco/Documents/Processing/brainColors/data/som/Jason - Timeflip.wav"); 
  som[1]=minim.loadFile("C:/Users/Vasco/Documents/Processing/brainColors/data/som/metal/System of a down- Chop Suey!.mp3");
  som[2]=minim.loadFile("C:/Users/Vasco/Documents/Processing/brainColors/data/som/hardcore/Bratkilla & C-Netik - Corona Virus.mp3");
  som[3]=minim.loadFile("C:/Users/Vasco/Documents/Processing/brainColors/data/som/hardcore/The Supreme Team - Carnival of Doom.mp3");

  //IMAGEM COMANDO
  outline = loadImage("C:/Users/Vasco/Documents/Processing/brainColors/data/img/outline.png");
  play = loadImage("C:/Users/Vasco/Documents/Processing/brainColors/data/img/play.png"));
  pause = loadImage ("C:/Users/Vasco/Documents/Processing/brainColors/data/img/pause.png");
}

void draw() { 
  background(255);

  setupIcon();

  //BRAIN
}

void setupIcon() {
  image (outline, 16, 548);
  image (play, -10, 545);
  image (pause, 35, 549);
}

I'm uploading the img to try explain better what i'm trying to do. The img on the left shows what i've got so far, the one on the right shows what i'm trying. What i want for now is t put the name of the music playing and use the icons (play, pause), which is the eyes of the sketch to pause and play the music.

Chrisir

this is a simple button example

it printlns something when you press a button

Chrisir

sorry, I posted the wrong code

Vasco

ok, i'm going to try it

Vasco

Thank you for all the help. but my teacher said i couldnt do any of my idea because some of the things i need to use, we dont give in class yet, and now i got to think in a new project, do a report and send all to him before 9.30am. Sorry for all the time you take with me in this failed project, ahahah. I hope I can count on your help in a next idea

Chrisir

you could do a simple image viewer

show an image

click a button, he goes to next image in folder etc.

Vasco

I need to do something generative. I was thinking, in some geometric stuff (squares, lines, etc) in illustrator, save the images individually and make random stuff in processing.

Something like this image

Vasco

and make a void keyPressed, to every time i click on a letter the all img goes random, a do new stuff

Chrisir

ok

this is 3D?

Chrisir

https://www.processing.org/examples/texturecube.html

you need a image file and name it berlin-1.jpg

Vasco

Im not sure...I was searching for some geometric images, and seeing the deep of the image, maybe.

Chrisir

and change P3D to OPENGL

Chrisir

use this maybe http://www.emgu.com/wiki/images/OpenCV_Chessboard.png

Vasco

i'm getting an error because a library
