Using defined colors from an array

Processing Beginners

I should somehow initialize the array list here ??? // kind of lost here

there are different ways :

valid:

before setup() :

color[] grays = new color [5];

in setup() :

  grays [0] = #FFFFFF;         
  grays [1] = #BEBEBE;
  grays [2] = #7F7F7F;
  grays [3] = #3F3F3F;
  grays [4] = #000000;

or like this

color[] grays = {
  #FFFFFF, 
  #BEBEBE, 
  #7F7F7F, 
  #3F3F3F, 
  #000000
};

Full Code





color[] grays = {
  #FFFFFF, 
  #BEBEBE, 
  #7F7F7F, 
  #3F3F3F, 
  #000000
}; 

float deg = 90; // 90 degrees
float rad = radians(deg); // convert to radians

void setup() {
  size(400, 400);
  frameRate(1);
}

void draw() {

  background (127);
  noStroke();

  float r = random(1);
  // println (r);

  translate (200, 200);

  if (r < 0.40) {
    rotate (rad);
  } else if (r > 0.40 && r < 0.50) {
    rotate (rad*3);
  } else if (r > 0.50 && r < 0.65) {
    rotate (rad*2);
  } else {
    rotate (rad*4);
  }

  // Would like a random selection from gray array list
  int index = int(random(grays.length));  
  println(index); 
  fill(grays[index]);

  // rect 
  rectMode (CENTER);
  rect (0, 0, 200, 200);

  arc (0, -100, 200, 200, 0, PI);
}
