Recitation 7: Functions and Arrays

Step 1:

float x = 0;
float y = 0;
float c = 0;
float a = 0; 
float b = 0; 
void setup() {
  size(800, 800);
  background(188, 245, 244);
}

void draw(){

   pattern(400,400,247,236,17);

}
void pattern(float x , float y, float a , float b , float c ){
  
  stroke(255);
  strokeWeight(4);
  fill (a,b,c);
  triangle(x, y, x+100, y, x+50, y-100);

  stroke(255);
  strokeWeight(4);
  line(x, y, x+20, y+20);

  stroke(255);
  strokeWeight(4);
  line(x+50, y-100, x+70, y-80);

  stroke(255);
  strokeWeight(4);
  fill (a,b,c+100);
  triangle(x+20, y+20, x+120, y, x+70, y-80);
}
  

Question 1:

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

Answer:

When the for loop is in setup(), it’s contents will repeat a limited amount of times- only as long as certain conditions are met. If it is placed in draw(), it can go on indefinitely.

Question 2:

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

Answer:

Arrays allow objects in code to be described efficiently. We can use Arrays in Processing to construct shapes, for example

I was only able to complete the first step during recitation. I will attempt the remaining steps on my own time.
