Hi,

Basically as described in the title. I'm working with the icon class which is great but when I set it to being a switch, setting broadcast to false does not affect whether it calls the controlEvent function. In code:

controlP5.get(Icon.class, "Iconcontroller") .setBroadcast(false) .setOn() .setBroadcast(true) ;

Does not function like I would expect it too. Has anybody encountered or solved this problem before. Thanks

Hello everyone. I have a question. We are doing a new media art postgraduate project,our lecturer wants to get us involved with processing. I have seven different sketches. They are all separately. I want to combine them like a slideshow or with a mouse click in one pde file, because its a story . But i have "if mousepressed" comment some of my sketches. Maybe a button can solve my problem. But i have no idea how to do this because I'm a beginner. I am attaching my sketches. Can you please help me? Thank you all warmly.

I am trying to figure out a way to scroll down to the last line of the GTextArea after each time text is set.

If you try my code you can see when the text reaches the bottom of the view nothing happens. I tried using getTextAsArray in combination with moveCaretTo in order to place caret at the end of the text, hoping it would scroll down. But getTextAsArray always returns an array with only one element, even after text goes to a new line.

Hi, I was wondering if anyone here can help me getting my head around PVectors. I am creating a visualization of points on Earth. For this I am creating an arrayList of PVectors, which get their data from a csv (Longitude, Latitute). My problem is the csv has over 88 000 lines and slows down the program when drawn in void draw() Therefore I wanted to initialize the PVectors in void createLocationPoints()) and only display them in draw with another funciton... For instance with giving the points a stroke weight. Can someone explain how I can display the function LocationVectors.add(new PVector(x, y, z)); in this example? I was thinking of something similar like Daniel Schiffmans simple particle example from the documentation but I can't quite get my head around it. Please be gentle, I am quite new to processing. Thanks a lot!

hej –

i know how to play/loop an existing video. but what if i have a folder in which videos will be copied (from an external source – in my case a raspberry pi that uploads captured video clips) dynamically?

can i add videos to my canvas on runtime? there is a function to list folder contents – but i don't know HOW TO dynamically add video sources to a running project.

is there any help? or a definitive "NO" …? thanks anyways!

I am still a beginner with code and I was hoping to get some help in changing original image to show when there is a loud noise, and the filtered image show when it is quiet. I wasn't really shown how to complete this in my past class and want to learn how to edit it so I know how to in the future. My past teacher didn't really teach it to well.

Here is code I have so far:

// libraries
import processing.sound.*;

// global variables
Amplitude amp; // audio amplifier
AudioIn in; // audio input
PImage original; // original image
PImage filtered; // image that will receive filtering
float volume = 0;

void setup() {
  size(740, 920); //was 640, 360
  background(0, 255, 255);
  // Create an Input stream which is routed into the Amplitude analyzer
  amp = new Amplitude(this);
  // set the input the mic channel 0
  in = new AudioIn(this, 0);
  // turn on the mic
  in.start();
  // feed the mic data to the amp
  amp.input(in);
  // give image files to the image variables
  original = loadImage("Musical Note.png");
  filtered = loadImage("Musical Note.png");
}

void draw() {
  //Draw normal
  if (mousePressed && (mouseButton == LEFT)) {
    ellipse(mouseX, mouseY, 40, 40);
    fill(random(255), random(255), random(255));
    noStroke();
    //erases
  } else if (mousePressed && (mouseButton == RIGHT)) {
    ellipse(mouseX, mouseY, 40, 40);
    fill(0, 255, 255);
    noStroke();
  }

  float volume = amp.analyze();
  if (volume > 0.5) { // check if volume is above threshold
    image(original, 0, 0); // display original image
  } else {

    // YOUR FILTER CODE GOES HERE

    image(filtered, 0, 0); // display filtered image
    PImage img;
    img = loadImage("Musical Note.png");
    image(img, 0, 0);
    image(filtered, 0, 0); // display filtered image
  }
}

Hi guys, I have a basic set up of an animation storyline in which when the user clicks the mouse or does certain interactions, it then runs the next 'screen' or next animation. The issue I'm having is that on screen 5 a click of the mouse plays a video I made in after effects. However, this video then stops on the last frame and stays. I cannot work out how to 'screen++' after the video stops. I have tried duration, millis, etc. and nothing seems to be working. Could somebody please shed some light on what might be going on, or how I could achieve this?

Hi colleagues, which tools/libraries are good for scanning sound samples and extracting values. The values again should work as a driver for the visualization. As I saw a few, not sure where/how to start...

[see below for code]

hi everyone, i just exported my sketch to Rhino for making 3d model but i realized that each of my lines exported as 2 parallel and make them useless for lofting!! is it possible to fix them in processing and make only one Cv line for each of them or is just a way processing generate them?!

(image from exported lines in rhino)

Thanks

I'm trying to run the example in the documentation for the "Sound" library (https://processing.org/reference/libraries/sound/SoundFile.html) but I'm getting an error. I'm running v1.3.2 of the library, under Processing 3.1.1 and Windows 7 Pro. I tried both the 32-bit and 64-bit versions of Processing. The only change I made to the code was to change line 9 to point to the mp3 file on my hard drive. But when I try to open the file, I get this error message:

The constructor "SoundFile(SoundFile, String)" does not exist.

The error message doesn't make any sense, at least to me. I'm passing "this" as the first parameter, just as in the example, and a string with the full path name of the mp3 file as the second parameter. Why does it think "this" is a SoundFile?

Is the "Sound" library still working?

Here's my code, although as I said, I only changed the one line which opens the file.

import processing.sound.*;
SoundFile file;

void setup() {
  size(640, 360);
  background(255);

  // Load a soundfile from the /data folder of the sketch and play it back
  file = new SoundFile(this,"C:\\Users\\owner\\Music\\% Attac\\01 Tonino Carotone & Manu Chao - La Trampa.mp3");
  file.play();
}

void draw() {
}

Good evening to everyone and beg your pardon for my english. I'm new here even if it's a little while i'm working on Processing. In fact I use Processing to control arduino2009 board on my ROV, but I've only a problem to fix before I go to explore the abyss! On the front of the ROV there's a IPwebcam that I had to mount orizzontally to insert it into an acrilic cilynder. Webcam's video is correctly shown on my processing screen, but obviously it's 90 degrees clockwise rotated. I'm not able to turn the video counterclockwise, is there someone who can help me? (Of course i cannot mount webcam in other way because now i can rotate it to look up-forward-down). Every help is really really welcome! Thanks in advance. Andrew

PS: i put some lines of the program i've to improve with rotating 90deg counterclockwise, now it's only flips video horizontally.. (i'm not able to do more...)

Capture cam;
PImage camMirror;
void setup(){
  size(640,480,P2D);
  cam = new Capture(this,width,height,30);
  cam.start();
  camMirror = new PImage(cam.width,cam.height);
}
void draw(){
  if(cam.available() == true){
   cam.read();
  }
  cam.loadPixels();
  //Mirroring the image
  for(int x = 0; x < cam.width; x++){
    for(int y = 0; y < cam.height; y++){
      camMirror.pixels[x+y*cam.width] = cam.pixels[(cam.width-(x+1))+y*cam.width];
    }
  }
 camMirror.updatePixels();
  image(camMirror,0,0);
          }

Hi. I'm 22yo design major student.

Sorry for the bad english. I might be suck to understand. I try to make some kind of interaction work that by writing some words, It becomes a short melody on processing. And you can see your typewriting like usual web environment. It don't have to be a certain word and I try to make them sound when enterkey pressed.

this is the example)

In blank space, cursor blinking. You write some short sentences. You press enterkey. It becomes little melody that matched the keycode that you pressed. Like if you write 'a little butterfly' It became 'a' note melody~ 'l' note melody~ 'i' note melody~.

I used Pfont function for the text and Minim for the sound part. However I can't make them work togher.

A little example will helps me to understand, I really appreciate.

Thanks for reading this mess.

I am using G4P GUI Designer creating a PID Controller Screen to interface serially with a custom designed Arduino PID Controller. I created many Custom Sliders using the GUI Designer, but I do not get Mouse Wheel events through the G4P Slider Control Event Method. I want to use mouseWheel Events since it provides greater control of value settings than with mouseDragged Events, when considering my old shaky hands. I DO GET the G4P Control mouseWheel Events in my "Main Window", but how do I translate the mouseWheel(Event) to spSliderChange(Object, Event)? Or better yet, how do I get the mouseWheel Events to occur in the GUI slider event handlers?

Example Slider generated by GUI Designer (I have 10 of them total in GUI) which do not get mouseWheel Events, however the G4P controls do get mouse drag and steady events:

public void spSliderChange(GCustomSlider source, GEvent event) { //_CODE_:spSlider:950263:
  println("custom_slider1 - GCustomSlider >> GEvent." + event + " @ " + millis());
} //_CODE_:spSlider:950263:

public void createGUI() {
    G4P.messagesEnabled(false);
    G4P.setGlobalColorScheme(GCScheme.BLUE_SCHEME);
    G4P.setCursor(ARROW);
    surface.setTitle("Sketch Window");
    spSlider = new GCustomSlider(this, 120, 410, 300, 80, "blue18px");
    spSlider.setShowValue(true);
    spSlider.setShowLimits(true);
    spSlider.setRotation(PI/2, GControlMode.CORNER);
    spSlider.setLimits(0.5, 1.0, -1.0);
    spSlider.setShowTicks(true);
    spSlider.setNumberFormat(G4P.DECIMAL, 2);
    spSlider.setOpaque(false);
    spSlider.addEventHandler(this, "spSliderChange");
}

GCustomSlider spSlider;

And this in my "Main Window" which does get mouseWheel Events on slider:

void mouseWheel(MouseEvent event) {
    println(" - mouseWheel >> GEvent." + event + " @ " + millis());
}

I appreciate your input, who ever responds. I am not a GUI designer, but rather a low level 'C' and 'C++' coder. Your help is appreciated!

Thank you!

I have designed some 3D objects in Sketchup that I would like to display in processing. Different surfaces of the model are painted with different textures. I then export as .dae with textures which creates a folder with .jpgs of each texture. I then import into MeshLab where my textures do show up correctly. I then export as a .obj which also creates a .mtl. That mtl has a list of the "materials" and their .jpg file name. When I show the obj in processing it only paints on the last material/texture in the mtl list over the entire model, including areas which should have the earlier materials. It's either only accepting the last one or is possibly painting each material over the entire model showing only the last one.

Is there a way to get processing to accept multiple materials/textures? If I open the .obj (not the dae) in mesh lab it shows the textures correctly so I believe it's exporting correctly.

Alternatively, is there a way in mesh lab to create a single jpg from the repeated (tiled) and multiple jpgs given? I think this might be called baking. UV mapping is another keyword I don't full understand...do I need to export this separately in meshlab and can it be used by processing?

Thanks

What's wrong with my code. When I run the code, it pops out a grey windows nothing inside there. The camera should be activated and detect motion in the screen

import processing.video.*;
int numPixels;
int[] previousFrame;
Capture video;

void setup(){
  size (640, 480);
  video = new Capture (this, width, height);
  numPixels = video.width * video.height;
  previousFrame = new int[numPixels];

}

void draw() {
  if (video.available()){
    video.read();
    video.loadPixels();
    int movementSum=0;
    loadPixels();

    for (int i = 0; i < numPixels; i++){
      color currColor = video.pixels[i];
      color prevColor = previousFrame[i];

      int currR = (currColor >> 16) & 0xFF;
      int currG = (currColor >> 8) & 0xFF;
      int currB = currColor & 0xFF;

      int prevR = (currColor >> 16) & 0xFF;
      int prevG = (currColor >> 8) & 0xFF;
      int prevB = currColor & 0xFF;

      int diffR = abs(currR - prevR);
      int diffG = abs(currG - prevG);
      int diffB = abs(currB - prevB);

      movementSum += diffR + diffG + diffB;
      pixels[i] = color(diffR,diffG,diffB);
      previousFrame[i] = currColor;
    }

   if (movementSum > 0){
     updatePixels();
     println(movementSum);
   }
  }
}

I'm currently working on a project that uses the Twitter4j library which, along with Processing, also implements JSONObjects. I'm getting an error that reads "The type JSONObject is ambiguous" because of this. I know how to specify it so that is uses the Twitter4j JSONObject class, but how do I specify for it to use the Processing JSONObject class?

Thanks!

Hi guys, I asked this once, but still can't make it works..

I want to make the sentence I make to convert little melody when enterkey pressed.

those are codes

    }
    if (key_num >= num) {
      key_num = 0;
    }
  }
}

void keyPressed() {
  if (key!=8) {
    t[key_num] = key;
    key_num++;
  } else if (key==RETURN||key==ENTER) {
    playSong=true;
  } else if (key==8) {

  }
  println("pressed " + int(key) + " " + keyCode);

keycodes are just examples..

I hope someone shows me the functional code that I can understand. thanks for reading..

Hi I programing a game and I discovered the framework Hermes. First I have never used a Framework so I'd like to know if i need to know some things about the code or anything and also if i can freely use it for my project. Then when I tryed to launch some of the examples from the folder, I have a compilation error which says that some of the function doesn't work.

Thanks for helping :)
