dear all,

i am quite new in processing. and i don't know if it possible to add extra information into println.

 with a lot of help  i have manage to generate a random show wheel but i need to add extra information in the println. 

i have renamed the images and what i would like is;

if pictures   1 to 5    are shown then add happy to the println, 

if pictures 10 to 16 are shown then add angry to the println

if pictures 21 to 24 are shown then add sad to the println.

is it possible?

i attach the code-----------

PrintWriter output;

int counter; // Automatically initialized at 0

final int DISPLAY_TIME = 5000; // 5000 ms = 5 seconds

int lastTime; // When the current image was first displayed

//String logFileName = "FileList.txt";

String imageFolderPath = "C:/Users/FerranGaldon/Desktop/final projects MA/- PROCESSING/_9_text_file_java/data";

File[] files;

PImage[] images;

// Second version, just listing the images

void setup()

{

  size(700, 700);

  File imageFolder = new File(imageFolderPath);

  files = imageFolder.listFiles(new FileFilter()

  {

    public boolean accept(File file)

    {

      if (file.isDirectory())

        return false; // Only files. A directory can have a dot in its name...

      String name = file.getName();

      return name.endsWith(".jpg") || name.endsWith(".png") || name.endsWith(".gif");

    }

  });

  images = new PImage[files.length];

  for (int i = 0; i < files.length; i++)

  {

    images[i] = loadImage(files[i].getAbsolutePath());

  }

  randomizeImages();

  showImageInfo();

  lastTime = millis();

}

void draw()

{

  background(255);

  fill(#005599);

  if (millis() - lastTime >= DISPLAY_TIME) // Time to display next image

  {

    counter++;

    if (counter == files.length) // Or IMAGE_NB

    {

      // Displayed all images, re-randomize the images

      randomizeImages();

    }

    lastTime = millis();

    showImageInfo();

  }

  image(images[counter], 0,0);

}

void randomizeImages()

{

  for (int i = images.length - 1; i > 0; i--)

  {

    int j = int(random(i + 1));

    // Swap

    PImage ti = images[i];

    images[i] = images[j];

    images[j] = ti;

    // Swap

    File tf = files[i];

    files[i] = files[j];

    files[j] = tf;

  }

}

void showImageInfo()

{

  File tf = files[counter];

  println("-----------------------");

  println("Name: " + tf.getName());

  println("-----------------------");

}

it returns 

what i need is that when a new image updates the mousePressed event return to 0 instead of returning 1.

this is the structure  i am using

here is the full code

is it possible to output an excel file with processing?

many thanks

i am very new in processing and i need to hard code a part of a project.

basically i am working with an EEG and i have been able to obtain raw data from it. 512 times a second. the values are being printer in a file i called "positions.txt."

now i need to get into this file (i have been said with an arraylist) and then apply a discrete fourier 

how can i do it?

thank you very much for your time

the project i am working is an interface with a random slidewheel on one half and a punctuation  (27 values) on the other half. 

now i have to implement a discrete fourier transform to create different bands from raw data coming from an EEG (neurosky) but i have never applied this algorithm.

here i attach the code from the main project and an example of the discrete fourier transform i have been said will work

hi there!!!

i am very new in programing and i do not know how to move from hard code to a simple way.

 or maybe i need to use an array.

attach code

i am using controlP5 to checkbox. 

i have got 27 buttons in 3 rows and 9 columns.   

i need to PrintWriter output; the button i pressed. but i can't find what do i need to write. i am using;

output.println("Checkbox selected:" + theEvent.group()); 

but it is not working.

and if possible instead of the number the example gives me

...

i need 

...

i am doing another sketch, and i have a doubt.

i need to create 3 rows of  9 circles with 40mm of separation among them horizontally and 50 vertically (total 27 circles or ellipses).

i can't adapt this sketch to my work

i attached code

---------------------------------------------------------------------------------

i am trying to create a random image sketch that change image every 15 seconds. but it does not work

specifically this line  image ( images [ counter ] , 50 , 50 ) ;

PImage[] images = new PImage[20]; // Supposing we have 20 images 
int counter; // Automatically initialized at 0 
final int DISPLAY_TIME = 15000; // 15000 ms = 15 seconds 
int lastTime; // When the current image was first displayed   
void setup() 
{ 
  size(500, 500);  
  for (int i = 0; i < images.length; i++) 
  { 
    images[i] = loadImage("img" + nf(i+1, 2) + ".png"); // nf() allows to generate 01, 02, etc. 
  } 
  lastTime = millis(); 
}   

void draw() 
{ 
  background(255); 
  fill(#005599); 
  text(frameCount, 10, 20); // Shows the sketch isn't stopped between each image   
  if (millis() - lastTime >= DISPLAY_TIME) // Time to display next image 
  { 
    // Increment counter, then compute its modulo, ie. reset it at zero when reaching images.length 
    counter = ++counter % images.length; 
    lastTime = millis(); 
  } 
  image(images[counter], 50, 50); 
}
