Wad-JS

A NodeJS module for extracting resources and loading Lumps/Data from WAD files

Supported Features

• Opening WAD and listing all Lumps
• Opening and exporting Graphics/Flat Lumps as PNG
• Map Data parsing and export to PNG
• Convert MUS data to Midi and export

Getting started

There are a few different classes/types that handle all these tasks,

let { Wad, Graphic, MapData, Flat, Mus2Midi, Playpal } = require("wadjs")

• Wad
• Graphic
• MapData
• Flat
• Mus2Midi
• Playpal

You can load a WAD file using the following

let Wadfile = new Wad("./path/to/wad");

once loaded you can then check on the lumps/files that the wad file has with a console.log of

Wadfile.getLump( index ) 

or check the LumpType here

Wadfile.detectLumpType( index )

When you know what file you are working with, you can choose the type and create a new object with the data needed

let mapData = new MapData(WadFile, "E1M1")
let graphic = new Graphic(WadFile.getLumpByName("TITLEPIC"))
let mus = new Mus2midi(WadFile.getLumpByName("D_E1M1"))

You can then write a png or midi using the following

fs.writeFileSync('./map.png', mapData.getImageData())
fs.writeFileSync('/music.mid', Buffer.from(mus))
fs.writeFileSync('/image.png', graphic.getImageData(WadFile))

More examples can be found in the test package included running Jest
