How to draw text to screen - when text are tweets using a particular hashtag?

Ilaj

Hi there - beginner here

I am working on a project where I aim to visualise tweets of a certain hashtag. I am using Processing 3 with Twitter4j. I am able to get the tweets to show up in the console but not in a sketch. I understand I need to use text() as well as setting a font before this but I am confused as to what the data or string data is supposed to be in text() in this particular case

Examples of text() being used I usually see a word or a sentence, but in this case I need it to be the tweets that use this particular hashtag that I have set in the string keywords.

Ultimately I don't want to just display text in the sketch but also some lines and colour and pretty visuals etc. but right now I am stuck on this!

Any help would be really very much appreciated!

fill(255);

text( tweet, 111,111);

Does that work?

Not sure what’s the problem...

Can you show your code?

Hey thanks for your response - when I put that in it gives the message "tweet cannot be resolved to a variable" - will show the code

TwitterStream twitterStream;
ArrayList<String> words = new ArrayList();

void setup() {     
  size(500, 500);
  background(255, 47, 0); 
  printArray(PFont.list());
  createFont("Arial", 24);
  openTwitterStream();
}  


void draw() {     
  background(255, 47, 0);
  stroke(255);
  fill(96);
  text(words, 111, 111);
}  


    void openTwitterStream() {  

      ConfigurationBuilder cb = new ConfigurationBuilder();  
      cb.setOAuthConsumerKey("XXXXXXXXXXXXXXXX");
     cb.setOAuthConsumerSecret("XXXXXXXXXXXXXXX");
      cb.setOAuthAccessToken("XXXXXXXXXXXXXXX");
      cb.setOAuthAccessTokenSecret("XXXXXXXXXXXXX"); 

      TwitterStream twitterStream = new TwitterStreamFactory(cb.build()).getInstance();

      FilterQuery filtered = new FilterQuery();

      String keywords[] = {
        "#romance"

      };

      filtered.track(keywords);

      twitterStream.addListener(listener);

      if (keywords.length==0) {
        twitterStream.sample(); // and calls these adequate listener methods continuously.
      }
      else { 
        twitterStream.filter(filtered);
      }
      println("connected");
    } 


    StatusListener listener = new StatusListener() {

      public void onStatus(Status status) {
        System.out.println("@" + status.getUser().getScreenName() + " - " + status.getText());
      }

      public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {
        System.out.println("Got a status deletion notice id:" + statusDeletionNotice.getStatusId());
      }

      public void onTrackLimitationNotice(int numberOfLimitedStatuses) {
        System.out.println("Got track limitation notice:" + numberOfLimitedStatuses);
      }

      public void onScrubGeo(long userId, long upToStatusId) {
        System.out.println("Got scrub_geo event userId:" + userId + " upToStatusId:" + upToStatusId);
      }

      public void onStallWarning(StallWarning warning) {
        System.out.println("Got stall warning:" + warning);
      }

      public void onException(Exception ex) {
        ex.printStackTrace();
      }
};

tweet was just an example of course

this seems to be the great line:

  System.out.println("@" + status.getUser().getScreenName() + " - " +       status.getText());

so you want something like:

String tweet = "@" + status.getUser().getScreenName() + " - " +       status.getText(); 

text(tweet, 111,111); 

after line 55

Write line and line after each other

to write line and line after each other, place String tweet=""; before setup() and then say :

// adding up the tweets (because of += and without "String ")
tweet += "@" + status.getUser().getScreenName() + " - " +       status.getText() +"\n"; 
text(tweet, 111,111, 300, 700);  // display with line break in a box
