Accel towards mouse

// Nature of Code

// Accelerating towards the mouse

// Lesson on vector based movement using "objects"

// Variables 

//   position = pos 

//   velocity = vel

//   acceleration = vel

​

// this variable will be the object

var w;

​

function setup(){

  createCanvas(640,360);

  // 

  w = new Walker();

}

​

function draw(){

  background(51);

  w.update();

  w.display();

}

​

function Walker(){

  this.pos = createVector(width/2, height/2);

  this.vel = createVector(0,0);

​

  this.update = function(){

    var mousePos = createVector(mouseX,mouseY);

    this.acc = p5.Vector.sub(mousePos,this.pos);

//  this.acc.normalize();

//    this.acc.mult(.05);

    this.acc.setMag(.05);

​

    this.vel.add(this.acc);

    this.pos.add(this.vel);

  }
