Reposted from On Air Now! Live Art Base Coding Session - Let's Download the 10 000 Moonrunner Token Meta Data, Images, & More - Don't Get Left Out Of The Pack - Follow Along:

On Air Now! Your questions & comment welcome. Let's try something different today - a live art base coding session - yes, you can - follow along - live right now right here as I post updates throughout the day.

Let's download the 10 000 moonrunner wolfpack collection - that is - all 10 000 metadata records, all 10 000 images, let's downsample the images to its true 50x50 pixel art dimensions, let's put together a historic world's first all-in-one composite image and much more.

Let's get started and - yes, you can - follow along. I try to document all steps using the artbase scripts / machinery and upload all scripts, token metadata, images and more over at the pixel art exchange. In the artbase.sandbox see /moonrunners »

Yes, you can. Say hello or introduce yourself.

Learn more about Moonrunners at the official links:

What's your take on Moonrunners? Yes, you can. Tell us and post a comment.

Let's get started. Step 1: Find and go to the Moonrunners token collection contract (on etherscan). See https://etherscan.io/address/0x1485297e942ce64e0870ece60179dfda34b4c625

Now click on the "Contract" register tab and on the "Read Contract" register tab - now you can query the contract for the tokenURI - that is - the link to the "off-chain" token metadata records. Let's try the token id #1 - enter the number 1 and hit the "Query" button. Bingo! The contract returns:

Try out the link in your browser and you will get the metadata in the java script object notation (json) format:

{"image":"https://moonrunners.herokuapp.com/api/1/image",
 "name":"Moonrunners #1",
 "description":"A collection of 10,000...",
 "attributes":[
    {"trait_type":"Background","value":"Yellow"},
    {"trait_type":"Body","value":"Pack"},
    {"trait_type":"Fur","value":"Trippy"},
    {"trait_type":"Mouth","value":"Hungry"},
    {"trait_type":"Eyes","value":"Evil"},
    {"trait_type":"Headwear","value":"Full Moon Bucket"}
  ],
  "dna":"2a30bd91f09abcb2a092860e55903f342180a6ec"}

Now try out some more token metadata records by changing the id and counting up (to 10 000 max.):

and so on. Next - let's find and have a looksie at the ("off-chain") images...

Yes - surprise, surprise - in the token metadata record you will find the link to the ("off-chain") image. Let's cut'n' paste the image link for the token #1 and again let's try out in your browser:

Bingo! Now try out some more image links by changing the id and counting up (to 10 000 max.):

Next let's have a looksie at the pixel art and let's bring in / on the art critiques...

Moonrunner Art Question #1: What's the dimension (width x height) in pixels of the image?

A: 300x300

Moonrunner Art Question #2: What's the zoom factor (5x? 10x?) used in the "for-sale display" image and what's the true pixel art dimension (width x height)?

A: The zoom factor is 6x and the true pixel art dimension 50x50 (6x50 = 300).

Now let's hand it over to the artbase machinery. Let's add the collection configuration in /moonrunnersnft/collection.yml reading:

 slug: moonrunnersnft
 count: 10000
 token_base: https://moonrunners.herokuapp.com/api/{id}
 image_base: https://moonrunners.herokuapp.com/api/{id}/image
 format: 50x50    # e.g. 6px x 50 = 300
 source: 300x300
 offset: 1

And now you can:

  1. Download all metadata one-by-one using:

    $ artbase moonrunnersnft m

  2. Download all images one-by-one using:

    $ artbase moonrunnersnft i

  3. Downsample (from 300x300 to 50x50) / pixelate all images one-by-one using:

    $ artbase moonrunnersnft px

  4. Generate an all-in-one composite:

    $ artbase moonrunnersnft composite

And more.

Questions? Comments?

Yes, you can. Post them on the D.I.Y. Punk (Pixel) Art reddit. Thanks.
