open a new sketch on a button click?

fadingbeat

hello hello. I'm building a small program for my thesis. It includes several buttons and i want those buttons, when clicked, to open a new sketch. Is that possible or is it done in some other way?

I'm familiar with Java but if it's done differently in Processing, i would like to know. Also i failed in search of this on forums and google, so i'm hoping for some direction if the question or topic already exists. Thank you

All the examples i found include only visual changes when button clicked, for example:

if(button.clicked)background(#somecolor);

I was hoping it would be that simple with invoking another sketch. thank you

You're looking for function runSketch(), in which we pass a String[] + a PApplet subclass instance in order to get another window running concurrently w/ other windows.

Too much info, i'm looking at everything and wondering what now..

I've found this example but i don't quite understand it.

https://forum.processing.org/one/topic/loading-other-sketches-from-within-a-sketch.html

This guy PhiLho says it would be best to merge all sketches. According to his examples (which you can find in his post ^^), does it mean i have to put all my code of each sketch in a separate class and then do as he did, extend them from main sketch class? Do I do it all in a completely new sketch? I'm totally confused with this one.

ok, different options:

processBuilder

when you have the sketches compiled as a exe-files they are just programs.

You could run them

join the sketches

then you can join the sketches on processing programming level into one.

let's say you have those 2 simple sketches:

int[] p = { 
  250, 50, 450
};

void setup()
{
  size( 800, 800);
  fill(255, 2, 2);
} // setup

void draw()
{
  background(255);
  for (int i = 0; i < p.length; i++) {
    ellipse(p[i], 100, 12, 12);
  }
} // draw

AND

float lowerRightCornerX = 210; 

void setup()
{
  // init
  size(800, 600);
} // func 

void draw() 
{
  // runs on and on 
  background(255);

  triangle(30, 75, 
    58, 20, 
    lowerRightCornerX, 75);
} // func 

void mousePressed() {
  if (lowerRightCornerX==86)
    lowerRightCornerX = 210;
  else 
  lowerRightCornerX=86 ;
} // func

only examples!!!

joining them you need one draw to handle what's going on. Therefore the draws above to draw1 and draw2.

Then join global vars and setup()

Don't have double names of vars etc. ;-)

The states tell you which sketch of the 2 old ones you are using.

//
// states
final int stateGame  = 0;  // consts // find better names!!!!!! 
final int statePause  = 1;
int state = statePause;    // current state


// stuff for draw1


int i; 
int[] p = { 
  250, 50, 450
};

// stuff for draw2

float lowerRightCornerX = 210; 


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

void setup()
{
  // init (runs only once)
  size(800, 600);
} // func 

void draw() 
{ 
  // draw() runs on and on 

  switch (state) {

  case stateGame: 
    // Game
    draw2(); 
    break; 

  case statePause:
    // Pause
    draw1(); 
    break;

  default:
    // error
    println("Error number 939; unknown state : " 
      + state 
      + ".");
    exit();
    break;
  } // switch

  fill(0);
  text("hit p to toggle", 77, 177); 
  //
} // func 

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

// functions for states - called from draw() 

void draw1()
{
  background(255);
  for (int i = 0; i < p.length; i++) {
    ellipse(p[i], 100, 12, 12);
  }
} // draw

void draw2() 
{
  // runs on and on 
  background(255);

  triangle(30, 75, 
    58, 20, 
    lowerRightCornerX, 75);
} // func 

// ----------------------------------------
// keyboard input 

void keyPressed() {

  switch (state) {

  case stateGame: 
    // Game
    keyPressedForStateGame();
    break; 

  case statePause:
    // Pause
    keyPressedForStatePause(); 
    break;

  default:
    // error
    println("Error number 1039; unknown state : "
      + state 
      + ".");
    exit();
    break;

  if (dist(mouseX, mouseY, width-70, 100) < 30 ) { 
    println ("Hit Pause.");
  }
} // func 
// =========================================

ok, one idea is that:

float ballX;
float ballY;

public void settings() { 
  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);
  }
}

these lines you could call from mousePressed on a button I think:

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

PM me if you need more

Best, Chrisir ;-)

I'm in big rush, will let you know the end of it ;) Thank you for your answers and help!!

Chrisir

All right

quark

The launch() method might be your solution

fadingbeat

That seems fairly easy and what i need quark, i put the right path but only the println line works, it doesn't open the app. I exported it before too.

This would be perfect if i could make it work.
