A library for building decoders for Tiled levels.

Motivation

I can not find good library that decodes Tiled data and is up to date, and use JavaScript ports was not an option.

Examples

module Main exposing (main)

import Browser
import Html
import Http
import Tiled
import Tiled.Level exposing (Level)


type Message
    = LevelLoaded (Result Http.Error Level)


load : String -> Cmd Message
load url =
    Http.get
        { url = url
        , expect = Http.expectJson LevelLoaded Tiled.decode
        }


main : Program () (Maybe Level) Message
main =
    Browser.element
        { init = \_ -> ( Nothing, load "./some_tiled_level.json" )
        , update = update
        , subscriptions = \_ -> Sub.none
        , view = view
        }


view : Maybe Level -> Html.Html Message
view model =
    Html.text (Debug.toString model)


update : Message -> Maybe Level -> ( Maybe Level, Cmd msg )
update msg model =
    case msg of
        LevelLoaded (Ok level) ->
            ( Just level, Cmd.none )

        LevelLoaded (Err _) ->
            ( model, Cmd.none )
