For this project I focused on making the mouseX & mouseY interaction feel intuitive. As you move mouseX left to right, the boxes in the first and third row rotate alternatively based on the mouseX position. The shade of the boxes also get lighter as you increase mouseX. The transparency of the the smaller white boxes in the middle row also decrease as mouseX decreases. MouseY controls the scale of the middle boxes as well.

The hardest part of this assignment for me was keeping track of which variables controlled which reactions, and fixing them accordingly when they didn’t work the way I wanted them to.

The most difficult aspect of this week’s project was making sure that all the elements I used were placed correctly. This would ensure that once the user starts moving the cursor, the elements would follow the path of the mouse properly.

When I began thinking of what I wanted to do for this project, I thought it would be interesting to do something using triangles. Initially, I thought of the drawing as having 8 different parts because I created 8 sections and thought I would need 2 shapes per section. But I ended up using 3 per section, and figuring out the coordinates of the shapes took a little bit longer than expected. Overall, I quite enjoyed creating this!

(Comment: For whatever reason, the very right part of my project is getting cut off on the website, even though the canvas width is set correctly.)

For this project, it seemed more important than ever to build a rough template (the shapes, colors, lines, etc.) and expand upon it later (making global/local variables to avoid magic numbers, creating several of the same type of object with slight differences, etc.).

I was afraid I wouldn’t be able to get the rotate() functions to do what I wanted; thank goodness I attended lecture when they mentioned push(), pop(), and translate().

P.S., regarding the visual not “completing” when the mouse is put all the way to the right, I believe it’s simply a limitation of the site. Even when I put data-width=1000 during embedding, the actual amount of canvas shown doesn’t change. Also, when opened using the html file, the visual does complete when the mouse is dragged all the way to the right.

I found this project to be rather difficult, however I really enjoyed experimenting with the different effects the movement of the mouse could have on the picture.

For this project I decided to make a dynamic drawing that stretches and shrinks a series of ellipses when the mouse is moved around the canvas. I was listening to music while I was coding it and it made me think that the shapes were almost dancing around on the screen 🙂

var rY = 500;
var rX = 300;
var rW = 50;
var u = 200;
var u1 = 400;
var mod = 100;

function setup() {
    createCanvas(600, 600);
}

function draw() {
  background((rX+mod)/3,(rY+mod)/3,(rX+rY+mod)/3);
  rectMode(CENTER);
  noStroke();
  fill("white");
  rect(rX,rY,rW,rW);
  if (keyIsPressed) {
      if (key == 'w') {
      rY = rY - 3;
      }
      if (key == 'a') {
      rX = rX - 3;
      }
      if (key == 's') {
      rY = rY + 3;
      }
      if (key == 'd') {
      rX = rX + 3;
      }
  }
}

Try to catch a star!

The pong assignment was really challenging, but I used a lot of the concepts from that (such as if statements, boundary points, and animation) in this program. I attempted to simulate a shooting star while also making it a kind of game.

This was a challenge for me because I had a lot of trouble getting my if statements to work.  Luckily after many hours of perseverance it came together!
