hi,
I am sure there must be a simple solution to this but i don't find it :(
I have an ellipse starting at 0,0, an the radius increases all the time until it is out of the window.
what i want is that there many ellipses on the screen, e.g all two seconds, and that this process never stops.

any help appreciated

regards
rettnoise

here is what i have so far:

float r;

void setup() {
  size(640, 480);
  background(0);
  smooth();
  noFill();
  strokeWeight(12);
  stroke(255);
}
void draw() {
  background(0); 
  make_ellipse();
  }


void make_ellipse() {
  ellipse(0, 0, r, r);
  r += 2;
  if (r > width*3) {
    r = 0;
  }
}

Hi,
I would like to convert my processing sketch to processing.js.
I tried with java mode in processing 2 but some questions came up:

- how to convert the processing font to a tft font?
- is the minim sound library supported?

You can view the sketch on my website
I have uploaded it as an applet made with processing 1.5.

any hints appreciated.

hi,
I have created a string array and the strings are randomly selected and diplayed after the DISPLAY_TIME.
Now I want to fade out and in using alphaVal over exact this time period, so that each time the string changes
the alphaVal starts changing from 0 ->255, ->255-0.
Any help appreciated.

regards
rettnoise


PFont font;
int counter;
final int DISPLAY_TIME = 3000; // 2000 ms = 2 seconds
int lastTime; // When the current image was first displayed

float rx = 120;
float ry = 160;
float alphaVal = 255;
float a = 1.5;

void setup() {
  size(640, 480);
  background(255);
  font = loadFont("ArialUnicodeMS-48.vlw");
  textFont(font);
  textSize(random(22, 35));
  fill(66, 190, 255);
  lastTime = millis();
}

void draw()
{
  background(255);
  if (millis() - lastTime >= DISPLAY_TIME) // Time to display next image
  {
    counter = int(random(quotes.length));
    textSize(random(20, 30));
    rx = random(10, 220);
    ry = random(10, 120);
    alphaVal = 255;
    lastTime = millis();
  }
  fill(66, 140, 255, alphaVal);
  text(quotes[counter], rx, ry, 400, 300);
  alphaVal -= a;
 
//  if (alphaVal < 0 || alphaVal > 255) {
//    a *= -1;
//  }
}

String[] quotes = {
  "string_1",
  "string_1",  
  "string_1",
  "string_1",  
  };
