How to use an array inside the fill function ?
Apr 22nd, 2010, 9:46am  
Hi , i got this array :

int[] als = { 12,25,38,50 };


i want now to use randomly one of these numbers in the array inside fill.


but i cannot get it.

how would that be ? this is my code :

Code:
int[] als = { 12,25,38,50 };
int largo = 80;
void setup() {
  smooth();
  size(800,800);
  frameRate(2);

}

void draw() 
{
 
for (int x = largo/2; x < width; x+= width/10-largo/2) 
{
	
  for (int y = largo/2; y < height; y+= width/10-largo/2)
  {
    noStroke();    
    
fill ();  // here is where i should choose a random array id
    ellipse(x,y,largo,largo);
   
    
}
 
} 

}

It is explained in the random() reference page.
So it is better to use fill( als[ int( random( als.length ) ) ] ) ; if you want to use the full array.
