It's really a good stepping stone, though I think it requires knowledge of programming outside Scratch. I'm going to be working on porting Scratch to Processing at some point in the next couple weeks, to make the transition better. It'll use Scratch block names with Processing parenthetical syntax, and include collision sensing built in like Scratch does. Once I have a significant portion done, I'll upload it somewhere and make it an open source project. 

I was just thinking the same thing. B)

Whoa, I got it yesterday too. Yay.

Hmm, I haven't found it too confusing yet. Are you doing some of the tutorials they have?

Yeah, but I just don't really understand most of it. If I'm not mistaken, void setup() and void draw() are two of the most important things, and I don't have a clue what they do. XD

Lol, I kinda felt like that too.
I don't really get Setup, but Draw is pretty much where all the action is. You can have variables and classes out of them, but everything else I think have to be in there. 

Idk ahhh.

Uh okay here's an experimental version of the game Shots I made without the game part.

Code:

ArrayList shooters = new ArrayList();
int stimer,ctimer,gtimer,osec,firedelay,shotNum;
boolean fr = false;
float maxAll;
PHist hist;
void setup(){
  size(700,500);
  background(#FFEEEE);
  text("Shots",width/2-10,height/2-50);
  smooth();
  shooters.add(new Shooter(int(random(30,width-30)),int(random(30,height-30))));
  hist = new PHist(0,height,width,(height/4)*3,8);
  osec = 2;
  firedelay = 59;
}
void draw(){
  background(#445599);
  maxAll = 0;
  for (int i = 0; i < shooters.size(); i++) {
    Shooter shooter = (Shooter) shooters.get(i);
    float maxShot = shooter.update();
    shotNum+=shooter.shots.size();
    maxAll = max( maxAll, maxShot );
    for(int j=0; j < shooter.shotSpeeds.length; j++){
      hist.dumpValue(shooter.shotSpeeds[j]);
    }
  }
  hist.onDraw();
  hist.clearBins();
  shotNum=0;
  stimer++;
  ctimer++;
  if (osec != second()){
    gtimer++;
    osec = second();
  }
  if (stimer==firedelay) stimer=0;
  if (ctimer==199){
    shooters.add(new Shooter(int(random(30,width-30)),int(random(30,height-30))));
    ctimer=0;
  }
  if (fr) println(frameRate);
  println(" ");
}
class Shooter{
  int x,y,r;
  int ofd = firedelay;
  int[] colour = new int[3];
  int tnum = int(random(0,firedelay));
  ArrayList shots = new ArrayList();
  float[] shotSpeeds;
  Shooter (int x_, int y_){
    x = x_;
    y = y_;
    r = 20; 
    colour[0] = int(random(0,255));
    colour[1] = int(random(0,255));
    colour[2] = int(random(0,255));
  }
  float update(){
    if (firedelay != ofd){if(tnum>firedelay) tnum = int(random(0,firedelay));ofd=firedelay;}
    fill(colour[0],colour[1],colour[2]);
    if (stimer==tnum) shots.add(new Shot());
    rect(x,y,r,r);
    float maxSpeed = 0;
    float sumSpeed = 0;
    shotSpeeds = new float[shots.size()+1];
    for (int i = 0; i < shots.size(); i++) {
      Shot shot = (Shot) shots.get(i);
      shot.update();
      shotSpeeds[i] = shot.vel.mag();
      maxSpeed = max( maxSpeed, shot.vel.mag() );
      sumSpeed += shot.vel.mag();
    }
    return maxSpeed;
  }
  class Shot{      
    int r = 5;
    PVector vel   = new PVector( random(-.1,.1),random(-.1,.1) );
    PVector loc   = new PVector( x+r/2, y+r/2 );
    PVector accel = new PVector(0,0);
    void update(){
      accel.x = ( random(-.5,.5) );
      accel.y = ( random(-.5,.5) );
      ellipse( loc.x, loc.y, r*2, r*2 );
      if (   loc.y + r >= height 
          || loc.y - r <= 0) {
          vel.y *=-1;
      }
      if (   loc.x + r >= width 
          || loc.x - r <= 0) {
          vel.x *=-1;
      }
      vel.add(accel);
      loc.add(vel);
    }
  }
}
class PHist{
 int x,y;
 int updateSpeed,oupdateSpeed;

 int nbins;
 int[] binValues;
 color[] binColours;
 PHist () {
   x = 0;
   y = height;
   w = width;
   h = height/2;
   nbins = 10;
   binValues = new int[nbins];
   binColours = new color[nbins];
   updateSpeed = 29;
   for ( int ii = 0; ii < nbins; ii++ ) {
     binValues[ii] = 20*ii;
     binColours[ii] = color(random(128,200),random(128,200),random(128,200),200);

   }
 }
 void clearBins(){

     binValues[ii] = 0;
   }
 }
 void dumpValue( float value ){
     for ( int jj = 0; jj < nbins; jj++ ){
         if ( value > jj*maxAll/nbins && value < (jj + 1)*maxAll/nbins )
             binValues[ jj ] += h/shotNum;
     }
 }
 void onDraw(){
       for ( int ii = 0; ii < nbins; ii++ ) {
         fill( binColours[ii] );
         rect( x+ii*w/nbins, y-binValues[ii], w/nbins, constrain(binValues[ii],0,h) );
       }
 }
}

uhhhhhhh wut

Here's some junk I'm working on:
*paste*

Code:

class Ball {
  PVector pos;
  boolean done = false;
  
  Ball(PVector p) {
    pos = p;
  }
  
  void update(float diff) {
    pos.z += diff;
    if(pos.z > 420) {
      done = true;
    }
  }
  
  void display() {
    pushMatrix();
    if(pos.z < -100) {
      fill(map(pos.z,-10000,-100,0,255));
    } else {
      fill(255);
    }
    translate(pos.x,pos.y,pos.z);
    ellipse(0,0,10,10);
    popMatrix();
  }
}

import processing.opengl.*;

int NUM = 500;
ArrayList<Ball> balls = new ArrayList();

float speed = -0.5;

float mx,my,camX,camY;

void setup() {
  size(500,500,OPENGL);
  
  fill(255);
  noStroke();
  smooth();
  
  for(int i=0; i < NUM; i++) {
    if(i%2 == 0) {
      balls.add(new Ball(new PVector(width-50,height-50,(-i*10)-20)));
    } else {
      balls.add(new Ball(new PVector(50,height-50,(-i*10)-20)));
    }
  }
  
  perspective(PI/4,width/ (float) height,0.01,5000);
}

void draw() {
  mx += (mouseX-mx)/10f;
  my += (mouseY-my)/10f;
  
  camX = mx - width/2;
  camY = my - height/2;
  
  background(0);
  translate(camX,camY);
  for(int i = (balls.size()-1); i >= 0; i--) {
    Ball b = balls.get(i);
    if(!b.done) {
      b.update(speed);
      b.display();
    } else {
      balls.remove(i);
      addRandomBall();
    }
  }
  
  speed += 0.05;
}

void addRandomBall() {
  balls.add(new Ball(new PVector(random(-width*2,width*2),random(-height*2,height*2),random(-15000,-5000))));
}

Mine tracks all the speeds of the shots onscreen into a histogram.

Ohhhh! That's what the rects were for! 

hey ProgrammingFreak, have you tried putting noLoop() in setup()? It causes draw() to run just once. 

:0 I found a "processing for the iOS" in the app store! Unfortunately my iPod to too outdated to use it ;-;

I tried using it yesterday but uh, I suck at this whole memorizing the commands.
I don't have the dedication and I need like someone explaining what every single command does.

Yes, I've seen it,  but you have to click the things, then you're on a different page that you have to read a bunch on, then you have to click back.

They need a list like this:
float(); - whatever it does explained simply

Though I may be the extreme example for laziness.
