usually my particle system lies under a boolean, and that boolean is activated/deactivated by a cp5 toggle. every time i toggle it to false, i want the ArrayList inside the particle system to be cleared, so the particle system starts fresh from zero instead of a simple interruption it's runtime.

so i put a ps.particles.clear(); in the toggle false condition. everytime it crashes and I get IndexOutOfBoundsException. it also happened to me with a bang and a button.

what is the most efficient way to really clear an ArrayList?

here is the code with whats going on.

main code

import controlP5.*;
ControlFrame cf;
RingSystem r;

boolean isRing = false;

void settings(){
   size(600,600);
}    

void setup(){

     //CONTROLP5
     cf =new ControlFrame(this, 400, displayHeight, "MENU", width, height);

     //RING SETUP
     cPos=new PVector(width/2, height/2, 0);
     r=new RingSystem(cPos);
}

void draw(){
  if (isRing) {
    if (frameCount%30==0) r.addRing();
    r.display();
  }
}

Ring System

class RingSystem{
 ArrayList<Ring> rings;
 PVector origin;
 RingSystem(PVector _origin){
   rings=new ArrayList<Ring>();
   origin=_origin.copy();
 }

 void addRing(){
  rings.add(new Ring(origin)); 
 }

 void display(){
   for(int i=rings.size()-1; i>0; i--){
    Ring r=rings.get(i);
    r.update();
    r.display();
    if(r.isDead()){
     rings.remove(i); 
    }
   }
 }
}

Ring/Particle

class Ring {
  PVector origin;
  float dim=0;
  float dimMax=400;
  float life=0;
  float alpha;

  Ring(PVector _origin) {
    origin=_origin.copy();
  }

  void update() {
    life++;
    //origin.y++;
    //dim=cos(radians(life))*life;
    dim=life;
    alpha=map(life,height*2,0,0,255);
  }

  void display() {
    pushMatrix();
    stroke(0, 255, 255,alpha);
    strokeWeight(6);
    noFill();
    translate(origin.x, origin.y, origin.z);
    //rotateX(radians(90));
    ellipse(0, 0, dim, dim);
    popMatrix();
  }

  boolean isDead() {
    if (life>height*2) {
      return true;
    } else {
      return false;
    }
  }
}

Control Frame

public class ControlFrame extends PApplet {

  ControlP5 cp5;
  Object parent;

  public void setup() {
    cp5 = new ControlP5(this);  

    cp5.addToggle("ringToggle")
      .setPosition(160, 50)
      .setSize(80, 80)
      .setValue(false)
      ;
}
  void ringToggle(boolean toggle) {
    if (toggle==true) {
      isRing=true;
    } else {
      isRing=false;

      r.removeAll(rings);
      for (int i=0; i<r.rings.size(); i++) {
        Ring ri=r.rings.get(i);
        r.rings.remove(i);
      }
    }
  }

}

Can anyone advise me in the right direction?

Kind regards

My problem is the following one: I would like to do a bar chart representing my 100 favorite songs (according to iTunes reproductions!), where you can change the table.sort, the disposition of the song in genre, artist, n° of reproduction, etc... with some buttons to do it. I've tried to do something with cp5 button, but the main problem is that if i maintain noLoop() the graph don't change, but if I take it away the graph goes crazy. I report down here the code and the CSV table!

Help me please, free hugs and the give of my final project if you do!

CODE:

import controlP5.*;

Here are the important bits. First, near the top is:

boolean runPause = true;

In the setup() block, among other lines, is this:

    RunPauseToggle = cp5.addToggle("runPause")
       .setPosition(ctrlOffsetX, ctrlOffsetY)
       .setSize(100, ctrlSizeY)
       .setFont(font)
       .setCaptionLabel("Running")
       .setColorCaptionLabel(0)
       .setValue(true)
       .setMode(ControlP5.SWITCH)
       ;

At the beginning of the draw() loop is this:

void draw() {
    if(runPause == false){
        RunPauseToggle.setCaptionLabel("Paused");
        return;
    } else {
        RunPauseToggle.setCaptionLabel("Running");
    }

As above, the first toggle of RunPauseToggle suspends draw() but writes PAUSED over RUNNING. The 2nd toggle displays a clean copy of RUNNING. This behavior continues on successive toggles. I've tried setting the label to all blanks (" ") and to no text ("") ahead of the "Paused" command line but that doesn't work. I've browsed the heck out of the forum but without finding a working example of what I want to do.

Thanks for looking and (fingers crossed) responding.

In CP5 examples the creation of a toggle control is this:

      cp5.addToggle("toggle")
         .setPosition(40,250)
         .setSize(50,20)
         .setValue(true)
         .setMode(ControlP5.SWITCH)
         ;

This generates not only the default coloration (black/blue) but places the "toggle" characters in all-caps below the graphic. My nearly-identical code is this:

    cp5.addToggle("run-pause")
       .setPosition(900, 50)
       .setSize(50, 40)
       .setValue(true)
       .setMode(ControlP5.SWITCH)
       ;

It creates the expected blue/black widget but no "RUN-PAUSE" text below the control. Why? Sure, I can add a text label and would do so to provide better captions for certain controls but it's still a puzzle.

import controlP5.*; Table table; ControlP5 cp5;

int col = color(255); controlP5.Toggle b;

boolean setVisible=true; int inside = -1; int x1= 0;

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

table = new Table();

cp5 = new ControlP5(this); table.addColumn("kapcsolo1",Table.INT);

TableRow newRow = table.addRow(); newRow.setInt("kapcsolo1", x1);

saveTable(table, "data/new.csv"); // create a toggle and change the default look to a (on/off) switch look b = cp5.addToggle("toggle") .setPosition(40,250) .setSize(50,20) .setValue(true) .setMode(ControlP5.SWITCH) .setVisible(true) ;

}

void draw() { background(0);

pushMatrix();

translate(280,100); if(inside==1) ellipse(0,0,100,100);

popMatrix(); }

void toggle(boolean theFlag) { if(theFlag==true) { inside=inside-1; x1=1; } else { inside=inside-1; x1=0; } }

I added the .setSwitch(true) to each button which acts like a toggle but the issues that when I click another button, the first button still stay highlighted.

How can I have a selected state?

Any idea?

Thanks.

I'm trying to put a bar to control the time / position when running a film, based on this example: https://forum.processing.org/two/discussion/8103/using-a-controlp5-slider-as-video-progress-bar

To show the bar as the elapsed time, ran regular ...

But how do if you want to advance the film? It did not work when I tried movie.position () (as sound).

Someone could give a tip, or where can I find some documentation on the subject?

Below the code I am using as an example:

import controlP5.*;
import processing.video.*;                              

ControlP5 cp5;
Movie movie1;

float md, mt;

int progress;
boolean play;

void setup() {
  size(600, 400);
  cp5 = new ControlP5(this);

  movie1 = new Movie(this, "D:/Projetos/Videos/Branca_de_Neve.mpg");
  movie1.play();

  ProgressBar p; // custom Controller class, see implementation below
  p = new ProgressBar(cp5, "progress"); // "progress" here will be linked to variable progress
  //p.setPosition(100, 300).setSize(200, 20).setRange(0, 1000).listen(true);
  p.setPosition(70, 330).setSize(350, 10).setRange(0,  (int) movie1.duration()).listen(true);

  // callback listener for TimeLine object   
  p.addCallback(new CallbackListener() {
    public void controlEvent(CallbackEvent theEvent) {
      if(theEvent.getAction() == ControlP5.ACTION_PRESS) {
        float x = theEvent.getController().getPointer().x();
        float a1 = 0;
        float a2 = theEvent.getController().getWidth();
        float b1 = theEvent.getController().getMin();
        float b2 = theEvent.getController().getMax();
        float val = map(x,a1,a2,b1,b2);
        theEvent.getController().setValue(val);
        println("now change movie time to ", val, movie1.time());

        //movie1.position(); //????
      }
    }
  }
  );

  // a toggle to switch between play and pause mode
  cp5.addToggle("play")
     .setPosition(10,375)
     .setSize(50,19)
     .getCaptionLabel().align(CENTER,CENTER);
}


void draw() {
  background(0);
  if (play) {
    // update the progressBar value/position
    // replace with audio-track position: progress = player.position();

    if (movie1.available()) movie1.read();
    image(movie1, 70, 40);

    //progress++;
    progress = (int) movie1.time();
  }
}

class ProgressBar extends Controller<ProgressBar> {

  public ProgressBar(ControlP5 theControlP5, String theName) {
    super(theControlP5, theName);

    setView(new ControllerView<ProgressBar>() {
      public void display(PGraphics pg, ProgressBar c) {

        pg.fill(!isMouseOver() ? c.getColor().getForeground():c.getColor().getActive());
        pg.rect(0, 0, c.getWidth(), c.getHeight());

        float val = map(c.getValue(),c.getMin(), c.getMax(), 0, c.getWidth()); 
        pg.fill(255);
        pg.rect(0, 0, val, c.getHeight());
      }
    }
    );
  }

  public ProgressBar setValue(float theValue) {
    return super.setValue(constrain(theValue, getMin(), getMax()));
  }

  public ProgressBar setRange(int theStart, int theEnd) {
    _myMin = theStart;
    _myMax = theEnd;
    return this;
  }
}

Thanks for listening

Default code would be: cp5.addToggle("toggleValue")

Well, that tries to resolve the event in the same window.

I can see you can pass a misterious object as first param, so I tried things like: cp5.addToggle(secondWindow, "toggleValue")

But that wont work either. The error is always this: Exception in thread "Thread-2" java.lang.NullPointerException

I think is previous versions one could create windows using controlWindow. Not sure. I'm using processing 3. And I'm creating the windows myself (in Eclipse context)

So, any clue on how to define a event listener or something like that?

Thanks in advance.
