Hi,
I looked at a lot of timer solutions in the forum, but they don't seem to 'fit'  my problem.  Perhaps you can help?

I'm trying to get a sketch working where the ball starts moving horizontally at a given digital clock-time - say 9.00 ( but for the purpose of the sketch, I set it only to seconds)  pauses for a few seconds, than drops vertically.
It seems to work, but I notice that the DISPLAY_DURATION is shorter than the expected 2 seconds. Also I'm not sure about the function of interval here. It does influence, but in an odd way.
What's wrong and how can it be solved?

many thanks for your time and thought
cheers

Hi there,
After a day of trying I really could do with some help. I know it's a common issue but I've tried to apply almost all relevant answers I could find, but I just can't get it right.
I can get an xml feed, I can do a keyword query in twitter ( thank you Forum!!) but I can't do a keyword querie in xml feeds.

(I'm after comparing all types of data queries and experimenting with their graphic expressions)
Here is the code I've 'constructed so far':

One day I'll hopefully be able to return the favors!!!

//-------------------------------------


String[] title;
//to highten the chance for something to show up I put in "have"
String[] good= {
  "good", "peace", "growth", "have"
};
//to highten the chance for something to show up I put in "no"
String[] bad = {
  "bad", "war", "cuts", "not"
};
XML xml;

PFont font;

ArrayList words;
//------------------------------------------------------
void setup() {
  size(700, 700);
  background(0);

  // Setup font
  font = loadFont("SansSerif-14.vlw");
  textFont(font, 14);

  words.add("good");
  words.add("pece");
  words.add("growth");
words.add("have");
  words.add( "bad");
  words.add("war");
  words.add("cuts");
words.add("no");
 
  ArrayList <String> words = new ArrayList <String> ();

  // Load RSS feed in this case BBC news
  xml = loadXML(  "http://feeds.bbci.co.uk/news/rss.xml");
  // Get title of each element
  XML[] title = xml.getChildren("channel/item/title");

  //----------------------------------
  try {

    QueryResult result = xml.search(title); //?????
    ArrayList title = (ArrayList) result.getTitles();

    title = new String[titlexml.length];
    for (int i = 0; i < titlexml.length; i++) {
      String title = titlexml[i].getContent();

      String[] input = title.split(" ");
      for (int j = 0;  j < input.length; j++) {

        //Put each word into the words ArrayList
        words.add(input[j]);
      }
    }
  }
  catch (Exception te) { // for when it goes wrong
    println("Couldn't connect: " + te);
  };
}
//------------------------------------------------------
void draw() {
  background(255);

  //Draw a word from the list of words that we've built
  int i = (frameCount % words.size());
  String word = words.get(i);

//show the results
  if (compareWordToArray(word, good)) {
    fill(0, 255, 0);
    text("good", random(width), random(height));
  }

  if (compareWordToArray(word, bad)) {
    fill(255, 0, 0);
    text("bad", random(width), random(height));
  }
}
//------------------------------------------------------
boolean compareWordToArray(String word, String[] wordArray) {
  for (int i=0; i<wordArray.length; i++) {
    if (word.equals(wordArray[i])) return true;
  }
  return false;

Hi There,
Learner driver here: I've tried various ways but I'm stuck
I've constructed a 'flower' and I want to rotate the stem+ flower from left to right ( but not the leave) I want it to move round a pivital point at the bottom of the stem. But I can't seem to make it rotate around that point.

btw I've haad simular problems with the leave, where I couldn't move the pivital point , making placement of the leave rather awkward- but I succeeded.

So this is what I'm after

this is how far I got:

 float x;
 float y;
float flowerAngle;
float angleChange =1.5;
final int ANGLE_LIMIT = 135;
 

void setup (){
  size (600, 400);
 smooth();
  }


void draw () {
  background (255);
drawLeave();
drawFlower ();
flowerAngle += angleChange;
 if (flowerAngle > ANGLE_LIMIT || flowerAngle < 0)
  {
    angleChange = -angleChange;
    flowerAngle += angleChange;
  }
}

  void drawFlower (){// draw flower and stem
  pushMatrix();
    translate (400, 300);
      //stem
      strokeWeight (6);
      noFill();
        stroke(96, 255, 82);
       rotate(radians(flowerAngle));
          arc(x, y, 250, 320, PI, 3.93);
   //flower
   noStroke ();
      fill (250, 0, 0);
 ellipse (x-75,y-130, 50,50);
       fill (250, 250, 0);
  ellipse (x-75,y-130, 20,20);
  popMatrix();
  }
 
 
    void drawLeave (){   //draw leave
  pushMatrix ();
      fill (96, 255, 82);
       translate (205,285);// make bottom of stem point zero
         rotate(radians(45)); //rotate the leafshape
      ellipse (-7, -40, 140, 20);
      popMatrix();
}
 

cheers
