Processing - Programming Language

[7alewi]

Processing is an open source programming language and environment for people who want to program images, animation, and interactions.

http://www.processing.org

I am currently studying programming languages and one of them is Processing, it is based on Java (basically the same). It is a new programming language they introduced at my university this year.

Any of you studied/used it before?

What is the most used programming language nowadays?

This language looks cool.
If you have any online e-books used by your university to teach it, then link me please.

Yes, please do link him, and soon, he will be teaching it in Balamand.

Actually, this is the future of the web...
I'm currently integrating ProcessingJS in web-pages using HTML5 canvas tag.
I'm coding something now, I will post it here when I finish...

Seriously I find it so interesting!

Well its my first year so we are studying the basics.. the book we use is called: Learning Processing: A Beginner's Guide to Programming Images. Download from HERE.

I am currently trying to create a game in processing (part of our project), I will post the code when I'm done!

Edit: By the way you can browse THIS website for some sketches done using processing

Look at the bottom left side of this page.
I coded this watch using ProcessingJS and embedded it in the page using Canvas HTML5 tag.

wow that was fast lol nice one

Im stuck

I wrote the following code, I used classes to state the variables and then I used an array which calls the class everytime it needs to draw the object (circle).

In the program, the array is written in the sketch and then I added a Tab to the sketch (named it Ball), and worte the class in the added Tab.

P.S: If I put this whole code in one sketch without the "Tab" it works! But if I try to do it the same way done in the book (Using Tab) it doesn't work. It says: "Cannot find class or type named Ball"

Any idea? Thanks


Class (In Tab named "Ball")

class Ball {
  
  color r;
  color o;
  color g;
  float xPos;
  float yPos;
  float xSpeed;
  float xSize;
  float ySize; 


 Ball() {
    r = color (196,18,18);
    o = color (227,144,18);
    g = color (19,157,52);
    xPos = height/2;
    yPos = width/2;
    xSpeed = 1;
    xSize = 80;
    ySize = 80;
 }
}

Array (In original sketch)

Ball[] myball = new Ball[100];

void setup() {
  size(400,400);
  smooth();
  
    for (int i = 0; i < myball.length; i ++ ) {
    myball[i] = new Ball(color(i*2),0,i*2,i/20.0); 
}}


void draw() {
  background(50);
  for (int i = 0; i < myball.length; i ++ )
  {
  myball[i].move();
  myball[i].display();
    }
  }
}

You need to import the class file.
Syntax: import CLASS_NAME

Try to run this

PFont fontA;
  int sphereDiameter = 10;
  boolean shoot = false;
  
  int randx()
  {
    return int(random(600));
  }
  
  int[] sphereXCoords = { randx(), randx(), randx(), randx(), randx() };
  int[] sphereYCoords = { 0, 0, 0, 0, 0 };
  
  void setup()
  {
    size(600,620);
  }
  
  void draw()
  {
    background(0);
    fill(color(0,255,0));
    stroke(color(0,255,0));
    triangle(mouseX-8, 580, mouseX+8, 580, mouseX, 565);
    fill(color(255,0,0));
    stroke(color(255,0,0));
  
    if(shoot==true)
    {
      sphereKiller(mouseX);
      shoot = false;
    }
  
    sphereDropper();
    gameEnder();  
  }
  
  void mousePressed()
  {
    shoot = true;
  }
  
  void sphereDropper()
  {  
    stroke(255);
    fill(255);
    for (int i=0; i<5; i++)
    {
      ellipse(sphereXCoords[i], sphereYCoords[i]++,
              sphereDiameter, sphereDiameter);
    }
  }
  
  void sphereKiller(int shotX)
  {
    boolean hit = false;
    for (int i = 0; i < 5; i++)
    {
      if((shotX >= (sphereXCoords[i]-sphereDiameter/2)) && 
         (shotX <= (sphereXCoords[i]+sphereDiameter/2)))
      {
        hit = true;
        line(mouseX, 565, mouseX, sphereYCoords[i]);
        ellipse(sphereXCoords[i], sphereYCoords[i],
                sphereDiameter+25, sphereDiameter+25);
        sphereXCoords[i] = randx();
        sphereYCoords[i] = 0;
      }    
    }
  
    if(hit == false)
    {
      line(mouseX, 565, mouseX, 0);
    }  
  
  }
  
  void gameEnder()
  {
    for (int i=0; i< 5; i++)
    {
      if(sphereYCoords[i]==600)
      {
        fill(color(255,0,0));
        noLoop();
      }
    }
  }
