We can launch game balls, but there’s no way to score yet. In this section, we’ll build a Basket object that will add to the score when struck by a launched ball. We’ll start with a little more code in Basket than we did with Launcher, but try to keep the steps smallish.

We’ll add the Basket prototype code below the Launcher prototype code. So add a few spaces below the closing curly brace of Launcher.prototype.launch, then add the Basket constructor.

function Basket(size, points) {
  this.size = size;

  this.height = 100/Math.log10(size);

  var r = Math.random;
  this.color = new THREE.Color(r(), r(), r());

  this.draw();
}

This constructor takes two arguments: the size of the ...
