[Answered] Growing random lines

Kevzog

Hi everyone! I'm trying to make random lines that grows one after another. I got this far:

int xrand = 300;
int yrand = 300;
int py = 0;
int px = 0;
int x;
int y;

void setup () {
  size (500,500);
  smooth();
}

void draw () {
  if (x<xrand) {
    x = x + 1;
  } else if (x>xrand) {
    x = x - 1;
  } else {
    px = x;
    xrand = (int) random(0,width);
  }
  if (y<yrand) {
    y = y + 1;
  } else if (y>yrand) {
    y = y - 1;
  } else {
    py = y;
    yrand = (int) random(0,height);
  }
  line (px,py,x,y);
}

void mousePressed () {
  println(xrand,yrand,px,py,x,y);
}

The problem is that when the lines are growing they're drawing "every single step" but i only want the straight line. Anyone know how to solve it? Thanks!!

Like this?

int xrand = 300;
int yrand = 300;
int py = 0;
int px = 0;
int x;
int y;

void setup() {
    size(500, 500);
    smooth();
    frameRate(10);
}

void draw() {
    x = xrand;
    y = yrand;
    line(px, py, x, y);
    xrand = (int) random(0, width);
    yrand = (int) random(0, height);
    px = x;
    py = y;
}

void mousePressed() {
    println(xrand, yrand, px, py, x, y);
}

Thanks Ater! Kind of... i want that with processing drawing the lines little by little and not all of sudden. That's why i put the x = x + 1;

Maybe i misspelled the problem: i didn't want the "between lines" when i was drawing the random lines. Those "between line" are drawing shapes and i only want the line(px,py,x,y);

How can i solve it?

look at lerp() to make a line grow slowly...
