Week 8 – Buzzing

For my assignment this week, I wanted to recreate something that follows an attractor with high speeds and natural orbiting movement. I wanted this attractor to buzz around more than flow.  I thought of bees around honey or something similar.

class Attractor {
  constructor(x, y) {
    this.pos = createVector(x, y);
    this.mass = 50;
  }

  attract(star) {
    let force = p5.Vector.sub(this.pos, star.pos);
    let distance = force.mag();
    distance = constrain(distance, 100, 500);
    force.normalize();

    let strength = (1 * this.mass * star.mass) / (distance * distance);
    force.mult(strength);

    return force;
  }

  update() {
    this.pos.add(p5.Vector.random2D().mult(5));
  }

  display() {
    // noFill();
    noStroke();
    fill(237, 208, 92);
    ellipse(this.pos.x, this.pos.y, 20, 20);
  }
}

I want the attractor to move at certain distances and have a certain strength, so the update function is what controls the movement of the attractor so that it buzzes around. I set the multiplying as a number of 5 and it was the perfect value for the attractor to buzz around.

class Bee {
  constructor(x, y) {
    this.pos = createVector(x, y);
    this.vel = p5.Vector.random2D();
    this.acc = createVector();
    this.maxSpeed = 100;          //speed of the particles 
  }

For my bee class, the most important attribute in this class would be speed as it gives that high speed buzzing effect of the bees and makes the final code look much more realistic.

let choice = random();
    if (choice > 0 && choice < 1/3) {
      fill(255, 215, 0, alphaValue);
    } else if(choice > 1/3 && choice < 2/3){
      fill(255, alphaValue);
    }
    else{
    fill(0,alphaValue)}
    noStroke();
    ellipse(this.pos.x, this.pos.y, 5, 5);

This code gives an even chance of the colours I wanted to present on the canvas and the opacity is dependent on how far away the bees are from the attractor. The further away, the less opaque.

Next time

I think next time, I want to try an idea of the attractor moving in a natural curve like a shooting star collecting more stars on the way.
