2 separate screens in Processing 3

gerome

I want to put animations on 2 separate screens, one in Java2D, one in P3D. The available examples for that seem to function for P2 e.g. Multiple Nested PApplets (v2.0) by GoToLoop in the discussion https://forum.processing.org/two/discussion/10937/multiple-sketches

I do not know enough about Java and Processing to adapt this code to P3. Could someone link me to a functioning P3 example.

Help is much appreciated.

thank you very much GoToLoop for this hint!

here is the solution to my problem which I have found on this site: https://forum.processing.org/two/discussion/13152/2-displays#latest With the void setup() method is was not possible to change the size of the PApplet window e.g. to fullScreen. So I had to change that line of code to public void settings() to make it possible. For notice I give here the slightly modified code:

float ballX;
float ballY;

public void settings() { // this line was: public void setup() { it inhibited the risizing of the window size
  size(100, 100);

  String[] args = {"SecondApplet"};
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);
}

void draw() {
  ballX = mouseX;
  ballY = mouseY;
  background(0);
  ellipse(ballX, ballY, 10, 10);
}     

public class SecondApplet extends PApplet {

  public void settings() {
    size(100, 100);
  }
  public void draw() {
    background(0);
    ellipse(ballX, ballY, 50, 10);
  }
}

... but now I have an issue with the 3D renderer if I apply a class to this sketch. I posted this here.

Hi, I want to create two separate screens windows, one show the text that I'm typing and the second one show an image for each letter typed. Eg. I type: "Hi." and it will appear an image for H and next to it an image for I. Can anyone help me? I'm new in Processing.

I modified the previous example to do what you require. You need to have in your sketch folder a folder named "data" and place in it two files, "h.jpg" and "i.jpg".

float ballX;
float ballY;
int fig=-1;

ArrayList<PImage> imgs;

public void settings() { // this line was: public void setup() { it inhibited the risizing of the window size
  size(100, 100);

  imgs = new ArrayList<PImage>();
  imgs.add(loadImage("h.jpg"));
  imgs.add(loadImage("i.jpg"));

  String[] args = {"SecondApplet"};
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);
}

void draw() {
  ballX = mouseX;
  ballY = mouseY;
  background(0);
  ellipse(ballX, ballY, 10, 10);
}   

void keyPressed() {
  if (key=='h' || key =='H')
    fig=0;
  else if (key=='i' || key =='I')
    fig=1;
}

public class SecondApplet extends PApplet {

  public void settings() {
    size(100, 100);
  }
  public void draw() {
    background(0);
    if (fig==0){
      image(imgs.get(0),0,0,width,height);
      ellipse(ballX, ballY, 50, 10);
    }
    if (fig==1){
      image(imgs.get(1),0,0,width,height);
      rect(ballX, ballY, 50, 10);      
    }
  }
}

I hope this helps,
