How to loop the whole proces?

in Core Library Questions • 1 year ago

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:

_________________________________________________________________________________________________

//Pre-setup

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

//Music
import ddf.minim.*;
Minim minim;
AudioPlayer introMusic;

//Images
PImage d, e;

//boolean movie
boolean movie = false;
boolean imagestarted = false;

//White rect
final int HowLongIsItWaiting1 = 3000;
final int HowLongIsItWaiting2 = 1000;
float m ;
char state='A';

//Setup

void setup() {
//workspace
size(640, 480, P2D);

//Intromusic
minim = new Minim(this);
introMusic = minim.loadFile("intro.mp3");
introMusic.loop();

//loadimages
d = loadImage("bg.jpg");

//Capture setup
myCapture = new Capture(this, width, height, 30);

//Movie shades setup
shades = new Movie(this, "film.mov");

//White rect setup
noStroke();
state='A';
m = millis();
}

//Make the Capture

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

//Draw

void draw() {

// Black background
fill(0);
rect(0, 0, 640, 480);

//The movie
if(movie == true) {
    image (d, 0, 0);
    if (imagestarted == false) {
    createdImage();
    image (e, 0, 0);
    }

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

//Intromusic stop when you press the mouse
if (mousePressed == true) {
    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
    } // if
} // func
}

//Mouse is pressed

void mousePressed() {

captureSave();
movieshades();
}

//End code

I use something like below - you can just call setup(), but I wouldn't recommend it.

// declare variables

void setup(){
// set size and renderer
// load your images, font's etc

init();
}

draw(){
// your code
}

void init(){
// initialize your variables
}

Thanks, I made this code below. And indeed it loops. But what you see is extremely slow. And I want that the whole project plays, and when it's finished , it starts at the beginning. Instead you have to press your mouse.

This is my code:

//Pre-setup

//Videos
import processing.video.*;
import codeanticode.gsvideo.*;
GSMovie shades;
Capture myCapture;

//Music
import ddf.minim.*;
Minim minim;
AudioPlayer introMusic;

//Images
PImage d, e;

//boolean movie
boolean intro = true;
boolean capture = false;
boolean whiteImage = false;
boolean movieShow = false;
boolean imagestarted = false;

//White rect
final int HowLongIsItWaiting1 = 3000;
final int HowLongIsItWaiting2 = 1000;
float m ;
char state='A';

//Setup

void setup() {
//workspace
size(640, 480, P2D);

//Intromusic
minim = new Minim(this);
introMusic = minim.loadFile("intro.mp3");
//introMusic.loop();

//loadimages
d = loadImage("bg.jpg");

//Capture setup
myCapture = new Capture(this, width, height, 30);

//Movie shades setup
shades = new GSMovie(this, "film.mov");

//White rect setup
noStroke();
state='A';
m = millis();
}

//Make the Capture

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

void movieEvent(GSMovie movie) {
movie.read();
}

//_________________________________________________________________________________________

// Draw

void draw() {

imagestarted = false;

//Zwart vierkant
fill(0);
rect(0, 0, 640, 480);

// de functies
mouse();
playIntroMusic();
captureImage();
imageShift();
imageFunc();
playMovie();

}
//_________________________________________________________________________________________

//Alle functies die worden aangeroepen

void playIntroMusic () {
if (intro == true) {
introMusic.play();
//introMusic.loop();
} else{
introMusic.pause();
}

}

void captureImage() {
    if (capture == true) {
image(myCapture, 0, 0);
saveFrame("data/createimage.jpg");
e = loadImage("createimage.jpg");
delay (300);
myCapture.stop();
}
}

void imageShift() {
    if (whiteImage == 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
    } // if
} // func
}

void imageFunc() {
// image shift
if(whiteImage == true) {
    image (d, 0, 0);
    if (imagestarted == false) {
    imageShift();
    image (e, 0, 0);
    }
}
}

void playMovie() {
if (movieShow == true) {
blend(shades, 0, 0, 640, 480, 0, 0, 640, 480, MULTIPLY);
shades.play();
} else {
shades.stop();

}
}

void mouse(){

if(mousePressed == true) {
intro = false;
capture = true;
whiteImage = true;
movieShow = true;
} else {
delay (300);
intro = true;
capture = false;
whiteImage = false;
movieShow = false;
}
}

You've already written code that executes in response to the mouse being pressed. This code restarts your sketch. Put this code in a standalone function called "restart". You can also replace the corresponding code in your mousePressed handler with a call to restart().

void restart()

{

// insert the code needed to restart the sketch

// (in which you reset all necessary variables)

intro = false;

// etc...

}

Now, basically you want to keep track of when the sketch started in a global variable. The millis() function gives you milliseconds since your sketch started.

int startTime = millis();

At some point, say 40 seconds, the sketch is over. That duration can also be represented in a global variable as well.

int sketchDurationInMilliseconds = 40*1000;

You can then detect this state of affairs in the draw routine, and reset the sketch when the time is up.

if (millis() - startTime > sketchDurationInMilliseconds) {

restart();

startTime = millis(); // ready to go again for the next round

}
