nwad

Read/write WAD files, as used by Doom et al.

npm install nwad

Usage

NB: All this module does is read from and write to the WAD data structure -
reading or creating the appropriate file header, indices etc. A WAD is just a
packed collection of "lumps" - to actually do anything interesting with the WAD
you will need to work with these lumps - nlump
is underway, this module serves as a base for that one.

$3

Takes a Uint8Array and returns a WAD data structure:

``javascript
{
"type": "", //"IWAD" or "PWAD"
"lumps": [] //an array of lumps, as below
}
`

The lump structure:

`javascript
{
"name": "", //name as per the WAD info table
"data": [] //a Uint8Array containing the lump data
}
`

Example:

`javascript
const fs = require( 'fs' )
const nwad = require( 'nwad' )

fs.readFile( 'doom.wad', ( err, buffer ) => {
if( err ) throw err

const wad = nwad.load( buffer )

console.log( wad.type, wad.lumps.length )
})
`

$3

Takes a WAD data structure (as above) and returns a buffer:

`javascript
const fs = require( 'fs' )
const nwad = require( 'nwad' )
const getLumps = require( './some-module-for-getting-lumps-from-somewhere' )

const wadBuffer = nwad.save({
type: 'PWAD',
lumps: getLumps()
})

fs.writeFile( 'my.wad', wadBuffer, err => {
if( err ) throw err
})
