Can return a value or an object containing multiple values.</p></li><li><p>display(): A function returning everything that should be displayed on the buyable after the title, likely including the description, amount bought, cost, and current effect. Can use basic HTML.</p></li><li><p>unlocked(): <strong>optional</strong>. A function returning a bool to determine if the buyable is visible or not.

A function that implements buying as many of the buyable as possible.</p></li><li><p>style: <strong>optional</strong>.

They are functionally identical, but "sell one" appears above "sell all". You can also use them for other things.</p><ul><li><p>sellOne/sellAll(): <strong>optional</strong>. Called when the button is pressed.
