Web APIs

Map Browser

Creeper World 1 and 2 do not have an easily readable map browser API and can only be accessed here:

Creeper World 3, 4 and Particle Fleet map browser API can be fetched from these URLs:

The data is gzipped, in XML format. Each map record contains the following information:

Shared values

  • g - string - Map GUID.
  • i - int - Map ID.
  • a - string - Map author name.
  • l - string - Map title.
  • w - int - Map width.
  • h - int - Map height.
  • t - int - Map upload UNIX timestamp, divided by 1000.
  • p - int - Forum thread ID (can be used to build URL).
  • u - int - Thumbnail image size (length).

CW4 values

  • b - int - Current map thumbs count.
  • s - string - Current map tags, delimited by commas.
  • o - int - Map objectives. Base 10 representation of available objectives in binary format. See Parsing the CW4 objectives value for more details.
  • v - int - Version number. Determines from which game version the map was uploaded. Presumably this is only incremented if an update with significant 4RPL additions is made, so older versions of the game cannot attempt to play them. Version 1.0 of the game did not have this system and will be able to play any map though.

CW3 and PF values

  • e - string - Map description.
  • s - int - Total current amount of scores posted.
  • r - float - Current map rating.
  • n - int - Total current amount of map ratings posted.
  • o - int - Total current amount of map downloads.

Score Query

Creeper World 1 does not have an easily readable score query API and scores can only be accessed through here:

Creeper World 2, 3, 4 and Particle Fleet score query API can be accessed through following examples:

Below is a list of available parameters to the score query APIs:

  • userfilter - Filter by user name. Leave empty for no user filter.
  • groupfilter - Filter by group name. Leave empty for no group filter.

The following arguments are exclusive, i.e. only use one of these at a time, as applicable:

  • customID - Custom map ID. Needed to query non-DMD custom maps.
  • gameUID - GUID of the map. Needed to query non-custom maps.
  • dmdID - CW3 only. DMD map ID. Needed to query DMD maps.

CW4 Chronom GUID

To query scores for Chronom maps, you must know what to supply to the gameUID parameter.

The value must look like follows: CHRONOM MAR 21, 2021, and then be encoded to base64.

Example JavaScript code for building a gameUID value for querying Chronom maps:

let months = ["JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC"];
let date = new Date();
let str = `CHRONOM ${months[date.getMonth()]} ${date.getDate()}, ${date.getFullYear()}`;
let gameUID = Buffer.from(str).toString('base64');

CW2 Code map GUID

To query scores for Code maps, you must know what to supply to the gameUID parameter.

The final string is based on the map's seed name, size and complexity.

Example JavaScript code for building a gameUID value for querying Code maps:

let name = 'think then after';
let size = 1; //0, 1, 2
let complexity = 2; //0, 1, 2
 
let hash = crypto.createHash('md5').update(name.toLowerCase().trim()).digest("hex");
let hnum = parseInt(hash.substring(0,8), 16);
let gameUID = "procedural" + hnum + "-" + size + complexity;

Campaign Mission GUIDs

To run score queries on campaign maps, you must know what to supply to the gameUID parameter. Below are long lists of campaign map GUIDs that can be supplied.

Misc Info

Parsing the CW4 objectives value

The objectives value from CW4 map data is a binary number saved in base 10 format, therefore to find which objectives exist on a map, we must look at each individual bit. There are 6 bits in total, as there are only 6 objectives.

Example JavaScript code for parsing the objectives value:

let o = 7;
 
let Custom =  (o >> 5 & 1) != 0; //false
let Collect = (o >> 4 & 1) != 0; //false
let Hold =    (o >> 3 & 1) != 0; //false
let Reclaim = (o >> 2 & 1) != 0; //true
let Totems =  (o >> 1 & 1) != 0; //true
let Nullify = (o >> 0 & 1) != 0; //true
 
//Conclusion: Map has Nullify, Totems and Reclaim objectives
