Was hoping someone might have some ideas as to the best method of uploading a json file to the wordpress uploads location so i can hopefully use the json with a sketch that will run on the site.

I will post an example of the code i have been trying :)

import http.requests.*;

public void setup() 
{
    size(400,400);
    smooth();

  //GetRequest get = new GetRequest("http://" + "forecast.weather.gov/MapClick.php?CityName=State+College&state=PA&site=CTP&textField1=40.7906&textField2=-77.8579");
  //GetRequest get = new GetRequest("http://" + "api.wunderground.com/api/dc43c0b770a7c1e0/forecast/q/PA/State_College.json");

    GetRequest get = new GetRequest("http://" + "www.accuweather.com/en/us/state-college-pa/16801/daily-weather-forecast/6787_pc");
    get.send();
    println("Reponse Content: " + get.getContent());
    println("Reponse Content-Length Header: " + get.getHeader("Content-Length"));
}

Thanks for any suggestions you may have,

    String trainInfo = "E215\n17:30 - Howth to Bray (-3 mins late)\nArrived Dublin Connolly next stop Tara Street";
    int start      = trainInfo.indexOf("(" ) + 1;  // STEP 1 
    int end        = trainInfo.indexOf(" mins", start);      // STEP 2
    String status  = trainInfo.substring(start, end);    // STEP 3
    int status_no   = int(status);                    // STEP 4
    println(status_no);

Whereas in my case I get an error at the point of the substring():

    void requestData() {   
      for (int i = 0; i < children.length; i++) {     

        XML announcementElement = children[i].getChild("PublicMessage");
        String announcement = announcementElement.getContent(); 

        int start      = announcement.indexOf("(" ) + 1;        // STEP 1 
        int end        = announcement.indexOf(" mins", start);  // STEP 2
        String status  = announcement.substring(start, end);    // STEP 3    ***error thrown at this point***
        int status_no   = int(status);                          // STEP 4

        println(status_no);
      }
    } 

[edit] Though not strictly related to Processing, I found a thread in the following forum that indicates that javascript does not permit substrings within arrays. I guess the same applies to Processing?: https://stackoverflow.com/questions/42429413/javascript-error-array-substring-is-not-a-function

The responder recommends to "slice and then remove the commas" or to use join(''). I have tried to to slice() and join(), based on Processing documentation but it's not working out.

Would anyone know of a way to get around this? Many thanks :)

import http.requests.*;

GetRequest get = new GetRequest("https://" + "api.yelp.com/v3/businesses/gary-danko-san-francisco");//Just a random example I found online. I know it's not an image.
get.addHeader("Authorization", "Bearer: <MY API KEY>");
//^ This is my attempt at using the API key
get.send();
println("Response Content: " + get.getContent());
println("Response Content-Length Header: " + get.getHeader("Content-Length"));

This gets printed in the console window

Response Content: {"error": {"code": "INVALID_AUTHORIZATION_METHOD", "description": "Invalid authorization method supplied."}}
Response Content-Length Header: 108

This is just a minimal reworking of the example code given in the HTTP requests library. As I said I'm very new to this and any pointers you could give would be much appreciated. Thanks in advance.

I've been working on a script where in very simple terms I would like a random beep to sound (Audioplayer beep - working!) and after that beep, a sequence of audio tracks to play (currently arranged in the array audio) and eventually audio recordings to be made (not set up yet).

My current issue is that

audio[0].play(); 

is working perfectly but not then playing the second audio track. I've tried setting this up as a separate event (

void playrecord()

) and have found this thread very helpful to get the crux of the code from @GoToLoop: https://forum.processing.org/two/discussion/12966/how-to-play-an-audio-file-sequentially.

Ideally I would like to sequence it as audio 0 play, record audio input 0 through microphone, audio 1 play, record audio input 1 through microphone. All before the next "beep" sound is made.

Can anyone suggest what is going wrong?

I've talked to Adam about how he did it, and he's using openFrameworks. He said he takes video from his webcam - down-samples it to those big pixels - then sends the greyscale (0-255) array information through UDP to Cinema 4d, and then has a videoIn python script (as an effector) which takes that information and displays the shading on a matrix of cubes (1 for each pixel in his down-sampled array).

I'm using Processing 3.0 and he said it would work just the same if I got everything working right. Well I found code that I've gotten to where the output is very similar to his video-downsampled.

import processing.video.*;

// Size of each cell in the grid, ratio of window size to video size
//Screen Pixels are 80 width and 60 height in this case 640/480
//Note: 128 large-pixel width at 1024 and 72 big-pixels at 576 height
int videoScale = 8;
// Number of columns and rows in the system
int cols, rows;
// Variable to hold onto Capture object
Capture video;

void setup() {  
  size(640, 480);  
  // Initialize columns and rows  
  cols = width/videoScale;  
  rows = height/videoScale;  
  background(0);
  video = new Capture(this, cols, rows);
  video.start();
}

// Read image from the camera
void captureEvent(Capture video) {  
  video.read();
}

void draw() {
  video.loadPixels();  
  // Begin loop for columns  
  for (int i = 0; i < cols; i++) {    
    // Begin loop for rows    
    for (int j = 0; j < rows; j++) {      
      // Where are you, pixel-wise?      
      int x = i*videoScale;      
      int y = j*videoScale;
      color c = video.pixels[i + j*video.width];
      fill(c);   
      stroke(0);      
      rect(x, y, videoScale, videoScale);    
    }  
  }
}

The above code gets me basically in the ballpark as far as a video downsampled to a manageable array size for UDP transfer. I've been able to get a simple UDP message sent from Processing 3.0 to cinema 4d in a python tag, which as I advance each frame I get the message (which is looping in processing) each frame I move forward. So in theory I'm getting there.

import hypermedia.net.*;

int port = 20000;
String ip ="127.0.0.1";
String message =new String("Hello");
UDP udpTX;

void setup(){
udpTX=new UDP(this);
udpTX.log(true);
noLoop();
}

void draw(){
udpTX.send(message,ip,port);
delay(499);
loop();
}

With this UDP transfer the string "Hello" gets sent in a loop with a little less than a half second delay. To the question! How do I meld the two? Have the camera start showing the down-sampled video and then be sending the black and white "big" pixel color data through the UDP connection? I'm new to this, and so filling in the gaps is a big challenge but I'm trying! If I can't get help though I probably will have to chalk this one up to being over my head. Hopefully someone here is a genius who can help me. :D

Im trying to receive osc on my mobile, using OscP5 library and android mode 4.0-beta2. Codes:

Android app

import oscP5.*;
import netP5.*;

OscP5 oscP5;
NetAddress endereco;

float x = 1.0;
float y = 2.0;
float z = 3.0;

void setup() {
  fullScreen();
  orientation(LANDSCAPE);
  textSize(100);
  oscP5 = new OscP5(this, 9000);
  endereco = new NetAddress("localhost", 10000); // not sure if i even need to import netP5
}

void draw() {
  background(0);
  fill(255);
  text("x = " + x, 20, 200);
  text("y = " + y, 20, 400);
  text("z = " + z, 20, 600);
}

void oscEvent(OscMessage mensagem) {
  // tests if any message is being received at all
  fill(255);
  rect(50, 30, 100, 100);

  if (mensagem.checkAddrPattern("/x")) x = mensagem.get(0).floatValue();
  else if (mensagem.checkAddrPattern("/y")) y = mensagem.get(0).floatValue();
  else if (mensagem.checkAddrPattern("/z")) z = mensagem.get(0).floatValue();
}

Java code running on my laptop

import oscP5.*;
import netP5.*;

OscP5 osc;
NetAddress endereco;

float x = 0;
float y = 0;
float z = 0;

OscMessage mx = new OscMessage("/x");
OscMessage my = new OscMessage("/y");
OscMessage mz = new OscMessage("/z");

void setup() {
  osc = new OscP5(this, 12000);
  endereco = new NetAddress("192.168.25.2", 9000);

}

void draw() {
}

void keyPressed() {
  if (key == 'q') {
    x += 10.4;
    mx.add(x);
    osc.send(mx, endereco);
    mx.clearArguments();
  } else if (key == 'w') {
    x -= 10.5;
    mx.add(x);
    osc.send(mx, endereco);
    mx.clearArguments();
  } else if (key == 'a') {
    y += 10.4;
    my.add(y);
    osc.send(my, endereco);
    my.clearArguments();
  } else if (key == 's') {
    y -= 10.5;
    my.add(y);
    osc.send(my, endereco);
    my.clearArguments();
  } else if (key == 'z') {
    z += 10.4;
    mz.add(z);
    osc.send(mz, endereco);
    mz.clearArguments();
  } else if (key == 'x') {
    z -= 10.5;
    mz.add(z);
    osc.send(mz, endereco);
    mz.clearArguments();
  }
}

They are both connected to the same Wifi network, im pretty sure the IP address is correct, but it just does not receive the message sent, the INTERNET permission is checked for the app. What can I be missing?

Using Processing 3.2.1, Android Mode 4.0-beta2, Android 6.0 (API 23), Zenphone 2 Laser Android 5.0.2.

I am scanning an image line by line and outputting the greyscale of each pixel to Pure Data via OSC, all of it is working ok but it seems super intensive for the computer, the fans are on full speed and sometimes Processing crashes a few minutes in.

Is there anything I can do to make this code less intensive? Might be missing something obvious?

It could be because of the frameRate, and if so are there any suggestions of other ways of doing this? So that I can still run the scanning pretty fast

Thanks in advance for any help

I used Processing to create a donation randomizer (basically gives me something random to do to make things interesting when someone donates a specific amount) and a swear counter (which tallies the swears I say via keyboard input and keeps track of how much money I owe).

The thing I wanted to do with it, though is make it show the total number of donations as well as the total amount donated thus far (not just the donations that I owe for swearing like it does now). I am unsure of how to write the Processing code to read the data off of the website I collect donations through, though. I'm also entirely unsure as to if such a thing is even possible.

Thank you in advance for the help! ^_^

But GET request work perfect.

Can somebody explain me how I fix this problem?

I use Processing 3.0 on MacOS 10.9.5

There are a ton of file upload examples using ajax/etc all over the web. But I'm missing the piece that takes the data created by .drop(). What am I not understanding about the data that drop() delivers? Have even tried copying and pasting the data from f.data from the console and into a new file and saving, but that doesn't work either... Seems like I'm missing something fundamental?

Here's some sample code:

var xhr = new XMLHttpRequest();
var formData = new FormData();

function gotFile(f) {
   console.log('gotFile: ' + f.name + ' ' + f.size + ' ' + f.type);
  formData.append('photos[]', f.data, f.name); //FAILING HERE, TypeError: Argument 2 of FormData.append is not an object.
  // Open the connection.
  xhr.open('POST', 'upload.php', true); //an upload script on server
  // Send the Data.
  xhr.send(formData);
}
// Set up a handler for when the request finishes.
xhr.onload = function () {
  if (xhr.status === 200) {
    // File(s) uploaded.
    console.log('uploaded');
  } else {
    console.log('upload error');
  }
};

I have successfully created the tcp connection between processing and matlab. I am using oscp5 library for that. I am sending an array containing x and y coordinates from processing and my intent is to draw a sine wave in matlab with these received x & y values.

My question is how i can separate the coordinates after receiving in matlab? Also, i think i need to alter some setting in tcpip object because i am not receiving the same values in matlab, which i am sending.

You can see the code and their values below.

OscMessage myMessage;
OscP5 oscP5tcpClient;

int xspacing = 16;   // How far apart should each horizontal location be spaced

float theta = 0.0;  // Start angle at 0
float amplitude = 75.0;  // Height of wave
float period = 500.0;  // How many pixels before the wave repeats
float dx;  // Value for incrementing X, a function of period and xspacing
float[] yvalues;  // Using an array to store height values for the wave
int x;

void setup() {
  size(640, 360);
  oscP5tcpClient = new OscP5( this, "141.44.219.161", 1234, OscP5.TCP);
  w = width+16;
  dx = (TWO_PI / period) * xspacing;
  yvalues = new float[w/xspacing];
}

void draw() {
  background(0);


  calcWave();
  OscMessage myMessage = new OscMessage("/test");
  myMessage.add(new float[] { x*xspacing, height/2+yvalues[x]});  =====>>> These values are sent to Matlab. 
  oscP5tcpClient.send(myMessage);
  print(x*xspacing, height/2+yvalues[x]);
}

void calcWave() {
  // Increment theta (try different values for 'angular velocity' here
  theta += 0.02;

  // For every x value, calculate a y value with sine function
  float x = theta;
  for (int i = 0; i < yvalues.length; i++) {
    yvalues[i] = sin(x)*amplitude;
    x+=dx;
  }
}

  noStroke();
  fill(255);
  // A simple way to draw the wave with an ellipse at each location
  for (int x = 0; x < yvalues.length; x++) {

  }

Now I first tried two apps both running in my computer (Both on local network 127.0.0.1 and swapped their ports) Here are the codes: Message sender (which send a random number every-time you mouse click in the applet window)

import oscP5.*;
import netP5.*;

OscP5 oscP5;
NetAddress myRemoteLocation;

float val;

void setup() {
  size(200, 200);

  /* start oscP5, listening for incoming messages at port 12000 */
  oscP5 = new OscP5(this, 12000);

  /* myRemoteLocation is a NetAddress. a NetAddress takes 2 parameters,
   * an ip address and a port number. myRemoteLocation is used as parameter in
   * oscP5.send() when sending osc packets to another computer, device, 
   * application. usage see below. for testing purposes the listening port
   * and the port of the remote location address are the same, hence you will
   * send messages back to this sketch.
   */
  myRemoteLocation = new NetAddress("127.0.0.1", 8000);
}


void draw() {
  background(255);
}

void mousePressed() {
  //constitute message:
  OscMessage myMessage = new OscMessage("/print");
  myMessage.add(random(10, 100));
  oscP5.send(myMessage, myRemoteLocation);
}

On the other hand the receiver processing app is kind of like this:

import oscP5.*;
import netP5.*;

OscP5 oscP5;
NetAddress myRemoteLocation;

float val;

void setup() {
  size(200, 200);

  /* start oscP5, listening for incoming messages at port 8000 */
  oscP5 = new OscP5(this, 8000);
  myRemoteLocation = new NetAddress("127.0.0.1", 12000);
}


void draw() {
  background(0);
}

void oscEvent(OscMessage theOscMessage) {
 val = theOscMessage.get(0).floatValue();
 println("Val: " + val);
} 

Now they seem to work on the computer ..

I imagined when porting it for android, I should just hardcode the ip-addresses .. But it doesn't work .. Tried to look at some help from the ketai library , but there's no direct example for a simple communication.. One example(wifi_direct_remote_cursor) explains but it's very scattered. I couldn't understand why I need to check if I was on the same network and get client addresses and all ..

Can someone help me establish a simple example like above below , The message sender is the Android app and the message receiver is the computer app ..

Thanks in advance ..
