why this program crashes?
Jul 30th, 2005, 6:05pm  
hello list,

I am trying to program my first sketch in Processing: a version of "How many lines are necessary to erase a black rectangle?", www.rgbdesigndigital.com.br/atravesdoespelho/howmanylines/. But it crashes. I don't know if I have to make some pause between an interaction and another in the loop, or change the condition of stopping the animation. The fact is that it crashed my computer (last version of Processing, windows xp).

The program is below:

background(255,255,255);
fill(0,0,0);
rect(50,50,500,250);
stroke(255,255,255);
while (!mousePressed) {
   float x1 = random (50,550);
   float x2 = random (50,550);
   float y1 = random (50,300);
   float y2 = random (50,300);
   line (x1,y1,x2,y2);
}


bye, and thanks for your time,
andrei

Try this!

Play with the variables to suit.

Code:

void setup() {
size(600,350);
background(255,255,255); 
fill(0,0,0); 
rect(50,50,500,250); 
stroke(255,255,255); 

}

void draw() {
if (mousePressed) { 
    float x1 = random (0, width); 
    float x2 = random (0, width); 
    float y1 = random (0, height); 
    float y2 = random (0, height); 
    line (x1,y1,x2,y2); 
    count++;
    }
} 

int count;

void mouseReleased() {

   println("no of lines: "+count);

}
