Exploding Die Demo

What is Exploding Die Demo?

When an exploding die comes up with the highest possible value it rolls again and adds the results



How the Template Works

The code for this demo creates an object showcasing a feature of the RollPlayer.js library and returns it to the template as demo.rollable. Both when the page loads and when the button above is pressed the template code calls demo.rollable.roll() and the returned result is displayed above. This process is identicle for all the demos allowing the explanations below to focus on only the object being demoed.

Every result is also logged to the console if you want to see a history after a bunch of button clicks.

  1. 1: var demo = function() {

  3. 3: return { rollable : d4 };
  4. 4: }();


We're creating a wrapper object called demo so that the template code can access the inner workings of this particular example.

  1. 1: var demo = function() {

We'll use a 4-sider for the sake of demonstration since it will explode easily. The arguments for explodingDie() work just like a standard die().

  1. 2: var d4 = RollPlayer.explodingDie(4);

Return an object so that our template code can access the star of this example as demo.rollable

  1. 3: return { rollable : d4 };
  2. 4: }();
