SC2kParser.js

This is a module that parses SimCity 2000 save files (*.SC2)

Install

npm install sc2kparser

Output

After the file is parsed, the parser returns a map of coordinates to tile info objects. See comments and save file documentation for more information about what each property is.

The struct looks like:

{
  tiles: [
    {
      alt: 50,
      building: 0,
      conductive: false,
      piped: false,
      powersupplied: false,
      saltwater: false,
      terrain: {
        slope: [0,0,0,0],
        waterLevel: 0
      },
      underground: {
        slope: [0,0,0,0],
        subway: true
      },
      water: false,
      watercover: false,
      watersupplied: false,
      zone: {
        bottomLeft: false,
        bottomRight: false,
        topLeft: false,
        topRight: false,
        type: 0
      }
    }
  ],
  cityName: "Cool City",
  daysElapsed: 0,
  founded: 34,
  money: 0,
  population: 255
}

Usage

Pass a typed array of bytes to the parse function like this:

let sc2kparser = require('sc2kparser');

// get file bytes somehow
let bytes = new Uint8Array(...);

let struct = sc2kparser.parse(bytes);
console.log(struct);

Here is an easy way to get a sc2k save file in the browser:

document.body.addEventListener('dragover', function(event) {
  event.preventDefault();
  event.stopPropagation();
}, false);
document.body.addEventListener('drop', function(event) {
  event.preventDefault();
  event.stopPropagation();

  let file = event.dataTransfer.files[0];
  let fileReader = new FileReader();
  fileReader.onload = function(e) {
    let bytes = new Uint8Array(e.target.result);
    let struct = sc2kparser.parse(bytes);
    console.log(struct);
  };
  fileReader.readAsArrayBuffer(file);
}, false);
