For-loop problem

MentalWork

Hello everybody,

i have a problem. I want to do less coding but im not sure how to declare about 2*1000 variables without writing each of them. I want to have a falling numbers display just like in the movie "Matrix". I have written parts of two of theses line. Here is my code.

My aim is to have falling number lines with different speed each, I have almost done the main programming, but my code declares every falling number and it would take a lot of time to write each down in the code. I was thinking of using a for-loop for declaring the variables but i'm not sure how to mange it exactly!

Thanks

// first line position variables
float a1;
float a2;
float a3;
float a4;
float a5;
float a6;
float a7;
float a8;
float a9;

float a11;

// first line numbers between 0 and 1
int i1 = 1;
int i2 = 0;
int i3 = 1;

//second line position

You should seriously consider taking a look at array's reference: http://processing.org/reference/Array.html o->
Here's some "The Matrix" example from the old forum: <):)

 */

int w, h, i;

void setup() {
  size(w = 1000, h = w>>1, JAVA2D);
  frameRate(30);
  noSmooth();
  textFont( createFont("Arial Black", 10, false) );
}

void draw() {
  fill(0, 10);
  rect(0, 0, w, h);

  fill(i = 0, h>>1, 0);
  while (i < w)  text( (char) random(h>>1), i += 020
    , ( (frameCount<<3) + noise(i)*i*h ) % h );
}

Hey buddy,

Ok, I will. I had that kind of idea, but i was not really sure about it. I'll try to figure out.

Thanks

As if it was written for me. Thanks
