Hello,

I made this code for a interactive installation. This is the idea of the installation: the visitor comes into a empty room (only music is playing), his shadow is projected on a wall, because of a lamp. When the visitor steps on a foot tile, his shadow is captured by a webcam and projected on the wall. (the lamp is switched off, and a beamer is projecting your freezed shadow on the wall). Now a movie is playing with people who are tearing you apart. When the movie stops, the whole proces can start all over again.

Now, that's a problem for me. I made a code that works, but because this is my first code I ever made in Processing and I didn't make a very good flow chart, I don't know how I can loop the whole proces.

I hope someone of you can help me a bit where to start. Thanks anyway!


By the way, this is my code:

boolean movie = false;
boolean imagestarted = false;

//White rect

    }
   
    blend(shades, 0, 0, 640, 480, 0, 0, 640, 480, MULTIPLY);
  }



  //Intromusic stop when you press the mouse

    introMusic.pause();
  }
}

//Hide till mouse is pressed

//Webcam capture, save image
void captureSave() {

  image(myCapture, 0, 0);
  saveFrame("data/createimage.jpg");
  e = loadImage("createimage.jpg");
  delay (300);
  myCapture.stop();
}



//Show movie shades
void movieshades() {

  movie = true;
  shades.play();
}

void createdImage() {

  if (mousePressed == true) {
    if (state=='B') {
      if (millis()-m>HowLongIsItWaiting1) {
        fill(255);  
        rect(0, 0, 640, 480);
        m = millis();
        state='A';
        imagestarted = true;
      } // if
    } // if
    else if (state=='A') {
      if (millis()-m>HowLongIsItWaiting2) {
        image (e, 0, 0); 
        m = millis();
        state='B';

    } // if

//Mouse is pressed

void mousePressed() {

  captureSave();

}


//End code

Hello,

I want to let Processing show an image after x seconds. And I want to hide another image simultaneously.

I don't know really how the seconds() and millis() works, so thats a problem.

I made this little script:

void draw() {
  float m = millis();
  delay(3000);
  fill(m % 50 + 1000);
  rect(0, 0, 640, 480);
}

A rectaingle appears after a few seconds, but I can't put it in another project because of the delay.
So is there a better way to do this?

Thank you?

Hello,

I want that Processing plays a song, but when you click on your mouse the song stops.
I've tried a several things, but nothing worked :(
I must say I'm still not very practised inProcessing.


This is the latest code I made:
_________________________________________________________________________________________________


// Pre setup


import ddf.minim.*;

Minim minim;
AudioPlayer introMusic;
AudioPlayer silenceMusic;

boolean music = true;


//setup


void setup(){
   minim = new Minim(this);
   introMusic = minim.loadFile("bloodbeat.mp3");
   silenceMusic = minim.loadFile("silence.mp3");

}

//Draw
//Song always plays

void draw(){

if(music == true){
   introMusic.play();
} else {
   silenceMusic.play();
}
}

//When you press your mouse, the song stops.

void mousePressed(){
  music = false;
}

I hope someone can help me. Thanks anyway!

Hello,

I've got this little problem, I want to play a song and when you press your mouse I want to let it stop of pause.
I guess it's a very stupid little mistake I make. But Processing said it couldn't find anything named 'musicPlays.'

Here's the code:
_____________________________________________

import ddf.minim.*;

boolean music = true;

Minim minim;
AudioPlayer player;


void musicPlays() {
   if (music == true) {
   minim = new Minim(this);
   player = minim.loadFile("liedje.mp3");
   player.loop();
   }
}

void mousePressed(){
if (music == false) {
musicPlays.stop();
}
}



Thanks anyway!

Here I am again. I made this following code in Processing, but nothing occurs. I think it have something to do with the booleans. I think I did something wrong in the void captureSave, movieShades and showImage with the 'if's,' but I can't figure out what :(

This is the code:
____________________________________________________________________________________________


//Pre-setup

//Videos
import processing.video.*;
Movie Shades;
Capture myCapture;

//booleans
boolean a = false;
boolean b = false;
boolean c = false;

//Images
PImage d, e;



//Setup

void setup() {
    //workspace
    size(640, 480, P2D);
 
    //loadimages
    d = loadImage("bg.jpg");
    e = loadImage("createimage.jpg");
 
    //Capture setup
    myCapture = new Capture(this, width, height, 30);
   
    //Movie Shades setup
     Shades = new Movie(this, "film.mov");
}


 //Make the Capture
 
 void captureEvent (Capture myCapture){
      myCapture.read ();
    }


//Draw

void draw(){
 
  //Is always visable
  image(d, 0, 0);
  }


  //Hide till mouse is pressed
 
  //Webcam capture, save image
  void captureSave(){
    if (a = true);
    image(myCapture, 0, 0);
    saveFrame("data/createimage.jpg");
    delay (300);
    myCapture.stop();
   }
  
   //Show movie Shades
    void movieShades(){
    if (b = true);
    image (Shades, 0, 0);
    Shades.play();
    }
   
  //Show saved image with blend
  void showImage(){
  if (c = true);
  blend(e, 0, 0, 640, 480, 0, 0, 640, 480, MULTIPLY);
  }
 
 
  //Mouse is pressed
 
  void mousePressed(){
    a = true;
    b = true;
    c = true;
  }
 
 
  //End code

Hello,

Here I am again. I've got a little problem. I've got the following idea: I want that processing makes a picture (of your shadow which is projected on a white wall), saves it in the data directory, put it back into processing with a blendmode (the white wall will be subtracted, and only your silhouette will be displayed) and BEHIND this silhouette I want to play a video.

But the problem is that the picture from the silhouette is been shown behind the video, instead of the silhoutte in front of the video.

a = a white background
b = the picture which is made with the webcam

This is the code till now:

___________________________________________________________________


import processing.video.*;

Capture myCapture;

PImage a, b;

Movie theMov;

void setup() {
  size(640, 480, P2D);


  a = loadImage("bg3.jpg");
  b = loadImage("plaatje.jpg");
  theMov = new Movie(this, "film.mov");

 
  {myCapture = new Capture(this, width, height, 30);
  }
 
}

void captureEvent (Capture myCapture) {
myCapture.read ();

}

void draw() {

image(theMov,0,0);
 
}

void movieEvent(Movie m) {
  m.read();
}



void mousePressed() {
   image(myCapture, 0, 0);
   saveFrame("data/plaatje.jpg");
   delay(300);
   myCapture.stop();
  
  image(theMov,0,0);
   theMov.play();
   aplhaImage(); 
}

void aplhaImage(){
  for (int i = 0; i < 4; i = i+1) {
  blend(b, 0, 0, 640, 480, 0, 0, 640, 480, MULTIPLY);
}
 
}

Thanks for te one who will help me! I'm not very practised in Processing.

Hello, I'm new here and not very experienced in Processing. But I hope someone will help me a bit.
I know how to capture a webcam and I know how to freeze the image when my mouse is pressed, like so:


import processing.video.*;


Capture myCapture;

int value = 0;

void setup ()
{
  size (640, 480);
 
  myCapture = new Capture(this, width, height, 30);
}

void captureEvent (Capture myCapture) {
myCapture.read ();

}

void draw() {
  image (myCapture, 0, 0);
  
}

void mousePressed() {
   myCapture.stop();
      
}

But I want that processing saves the freezed image and put it into the 'data' directory. Next I want to put that saved image back into processing with a blendmode.

So, first does anyone of you know how to save an image and put it into the data directory?
You will help me a lot! :D

Thanks anyway!
