Define max_value for extraAttributes?

[j-greig]

Is it possible to set a max_value for randomised values created using extraAttributes?

As per the metadata standards on OpenSea: "Adding an optional max_value sets a ceiling for a numerical trait's possible values. It defaults to the maximum that OpenSea has seen so far on the assets on your contract. If you set a max_value, make sure not to pass in a higher value."

https://docs.opensea.io/docs/metadata-standards#numeric-traits

In our case we'd set max_value to 100 and be generating a number between 0 and 100.

Thanks! :)

Yes, the extraAttribute config is open to static data or functions.

In this case, max_value would be a fixed values. something like

const extraAttributes = () => [
  {
    trait_type: "Aqua Power",
    display_type: "boost_number",
    value: (Math.random() * 100).toFixed(0),
    max_value: 100,
  },
]

Will return an attribute like the following:

   {
      "trait_type": "Aqua Power",
      "display_type": "boost_number",
      "value": 79,
      "max_value": 100
    }

Perfect, thank you for this :)
