Recitation 7 – Arrays – Kevin Nader

Introduction: 

For this recitation, we were tasked with creating an array. Similar to animation, I also find arrays a bit confusing so this recitation was very helpful.

My Array:

This is a video containing my array. I was unable to make it to step four as there was no time left in the recitation, however this is what I ended up with.

Spooky

Code:

void setup () {
  size(600, 600);
  background(0);
  //drawNightmare(360, 240, color(120, 60, 0));
  //drawNightmare(240, 420, color(140, 50, 32));
  //drawNightmare(510, 140, color(240, 34, 88));
  //for (int i=0; i<100; i++) {
  //drawNightmare(random(0, width), random(0, height), color(random (0, 255), random(0, 255), random(0, 255)));
  //}
}

void drawNightmare(float x, float y, color c) {
  fill(c);
  ellipse(x, y, 150, 150);

  fill(255);
  ellipse(x-25, y-15, 30, 20);
  ellipse(x+25, y-15, 30, 20);
}

void draw () {
  for (int i=0; i<100; i++) {
    drawNightmare(random(0, width), random(0, height), color(random (0, 255), random(0, 255), random(0, 255)));
  }
}

Homework Questions:

Q1: In your own words, please explain the difference between having your for loop from Step 2 in setup() as opposed to in draw().

Answer: While setup runs the code once, void draw runs it over and over again.

What is the benefit of using arrays?  How might you use arrays in a potential project?

Arrays make it easy to deal animations containing a large number of different entities. This functions could be used to create complex patterns for future projects.
