d30 Demo

What is d30 Demo?

If your house rules dictate that the die(30) should be purple or emerald you'll have to use your imagination



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.
