This is the public code repository for all things Wyldcard

For an overview on what Wyldcard is, check out the introductory blog post. After spending seven hours in the top position on Hacker News, I decided to crowdfund a Wyldcard DevKit on Crowd Supply

Game Development on Wyldcard

If you have a Wyldcard DevKit, you can program your own functionality and implement game mechanics using JavaScript. (You could also dive into a deeper level and program in any language you want, more on that later)

A simple Wyldcard demo that displays a random image on a card whenever a button is pressed could look like this:

let fs = require('fs/promises')
let path = require('path')

let { Plinth, imageUtilities } = require('@wyldcard/drivers')

async function main() {
  let plinth = new Plinth('devkit')

  let displayRandomImage = function(well) {
    return async () => {
      let image = await imageUtilities.randomImage()
      well.displayImage(image)
    }
  }

  plinth.wells.forEach((well) => {
    well.onAButtonPress(displayRandomImage(well))
    well.onBButtonPress(displayRandomImage(well))
    well.onCButtonPress(displayRandomImage(well))
  })
}

main()

In order to get to running this code, we need to go over the following:

• Setting Up a Development Environment
• Using the Wyldcard JavaScript SDK
• Formatting Images

If you want to design your own Wyldcard-compatible hardware, check out:

• Hardware Documentation

This repo also contains

• Examples and Demo code
• napi-rust-drivers - The core Rust code which runs the Wyldcard e-paper displays and the javascript native api wrappers which form the SDK
• images - Information about images, how to format them, programs for formatting and sending them to the Wyldcard plinth and some sample images to use
