Hi everybody!

I'm trying to use a playstation eye camera as a mouse. I tryed different ways, using different libraries but I always become the same error message: "Error while setting up Capture".

There is this disscution on the old forum ( http://processing.org/discourse/yabb2/YaBB.pl?num=1251903672/4) where somebody says it works only on an iMac. It was in 2009, maybe somebody has a current version of it? Would be great!

Cheers

sliders & text

Hi!

For my first project with processing, I try to modify some text using sliders. I'd like that on key pressed the sliders affects just one part of the text but I have no idea how to do that. It's probably really simple but I'm quite new with processing. Has anyone an idea? Thanks!

code:

String textTyped = "J'ai faim_j'ai envie_d'aller_au_macdo!!!";

String [] Sentence = splitTokens(textTyped, "_");

splitLetters[] words = new splitLetters [Sentence.length];

import geomerative.*;

import controlP5.*;

ControlP5 controlP5;

ControlWindow controlWindow;

public float MYGAP = 4.5;

public int MYTHICKNESS = 2;

public int MYRANDOM = 0;

public float MY_VAL = 0;

RFont font;

void setup() {

  size(1324, 1350, P3D);

  controlP5 = new ControlP5(this);

  controlP5.setAutoDraw(false);

  controlWindow = controlP5.addControlWindow("externalWindow", 0, 0, 200, 200);

  controlWindow.hideCoordinates();

  controlWindow.setBackground(color(40));

  Controller mySlider1 = controlP5.addSlider("MYGAP", -10, 0, MYGAP, 20, 20, 100, 10);

  mySlider1.setWindow(controlWindow);

  Controller mySlider2 = controlP5.addSlider("MYTHICKNESS", 0, 50, MYTHICKNESS, 20, 40, 100, 10);

  mySlider2.setWindow(controlWindow);

  Controller mySlider4 = controlP5.addSlider("MYRANDOM", 0, 20, MYRANDOM, 20, 60, 100, 10);

  mySlider4.setWindow(controlWindow);

  Controller mySlider6 = controlP5.addSlider("MY_VAL", -1, 1, MY_VAL, 20, 100, 100, 10);

  mySlider6.setWindow(controlWindow);

  controlWindow.setTitle("x4 Sliders");

// smooth();

  RG.init(this);

  font = new RFont("FreeSans.ttf", 60, RFont.LEFT);

  RCommand.setSegmentLength (1);

  RCommand.setSegmentator(RCommand.UNIFORMLENGTH);

  background(0);

  stroke(255);

  noFill();

  for (int k = 0; k < Sentence.length; k++) {

   words[k] = new splitLetters(Sentence[k]);

  }

}

void draw() {

  background(0);

  for (int k = 0; k < Sentence.length; k++) {

   words[k].mySplit(k);

  }

  if (key == '1') {

   words[0].transX = mouseY;

  }

  if (key == '2') {

   words[1].transX = mouseY;

  }

  if (key == '3') {

   words[2].transX = mouseY;

  }

  if (key == '4') {

   words[3].transX = mouseY;

  }

  if (key == '5') {

   words[4].transX = mouseY;

  }

}

class splitLetters {

  String mySentence;

  float transX = 30;



  splitLetters (String _mySentence) {

   mySentence = _mySentence;

  }

  void mySplit (int textDist) {

   if (mySentence.length() > 0) {

   RGroup grp;

   grp = font.toGroup(mySentence);

   grp = grp.toPolygonGroup();

   RPoint[] pnts = grp.getPoints();

   pushMatrix();

   translate(transX, 0 + -600 + (100 * textDist)); // calculate Sentence.length to fontsize

   for (int j = 0; j < pnts.length; j++ ) {

   float diameter = (MYRANDOM);

   if (j%2 == 0) {

   ellipse(pnts[j].x+100+MYGAP*20+(j*+(MY_VAL/2)), pnts[j].y+700, MYRANDOM, diameter );

   strokeWeight(MYTHICKNESS);

   }

   }

   popMatrix();

   }

  }

}
