The goal of the library is to offer a small, simple game development environment which aspires to be as charming as PICO-8.

There are deliberate limitations to keep things simpler and to encourage the 8-bit aesthetic.

Aspirational specs:

• Display: 128x128 16 colours
• Sprites: 128 8x8 sprites
• Map: 128x32 cels
• Controls: 2 6-button joysticks

• Be a nice little playground
• Be a simple teaching tool
• Be a nice way to write small games

Install from http://package.elm-lang.org/packages/micktwomey/elmo-8/latest

1. elm package install micktwomey/elmo-8
2. Edit Hello.elm
3. Download examples/birdwatching.png
4. elm reactor
5. Go to http://localhost:8000/Hello.elm

Hello.elm:

import Elmo8.Console as Console
import Elmo8.Pico8 as Pico8

type alias Model = {}

draw : Model ->  List Console.Command
draw model =
    [ Console.putPixel 10 10 Pico8.peach
    , Console.print "Hello World" 10 50 Pico8.orange
    , Console.sprite 0 60 90
    ]

update : Model -> Model
update model = model

main : Program Never
main =
    Console.boot
        { draw = draw
        , init = {}
        , update = update
        , spritesUri = "birdwatching.png"
        }

The result should look like this:

To play with the examples in this repo:

1. git clone
2. elm package install (not required but useful to check dependencies)
3. elm reactor
4. Look in http://localhost:8000/examples/
