OTBM2JSON

NodeJS library for programmatically modifying Open Tibia Binary Mapping files. This framework reads .otbm files and parses them to an intermediary JSON format. This JSON structure can be changed programatically to make generic modifications. Once a change has been committed to the structure, it can be encoded back to an .otbm file.

JSON Structure

The structure of the intermediary JSON format read from and to .otbm can be seen in the example OTBM.json.

Usage

Import the library in your script:

const otbm2json = require("./otbm2json.js");

The library provides two functions for reading and writing OTBM:

data = otbm2json.read(filename);

** Modify the data object here **

otbm2json.write(filename, data);

For an example see below.

Example

An example script examples/example.js is provided. This script uses the examples/void.otbm (8x8 void area) in this repository and replaces all void tiles with chessboard tiles and writes the result to examples/chess.otbm.

Version

Current version 0.2.0. This is a work in progress.

OTB2JSON

Based on OTBM2JSON library which reads .otb files and parses them into JSON format. As in original library, file can be later parsed again into .otb file to use it in RME, otitemeditor or OTServer.

Usage

Import the library in your script:

const otbm2json = require("./otb2json.js");

The library provides two functions for reading and writing OTB:

data = otb2json.read(filename);

** Modify the data object here **

otb2json.write(filename, data);

Example

Inside examples/otb directory there are 3 files:

• unpack.js which converts included items.otb file from RME for 8.60 version into items.json
• pack.js which can convert generated items.json into newItems.otb
• test.js which:
  1. creates items.json from items.otb
  2. creates newItems.otb from items.json
  3. creates newItems.json from newItems.otb

and you can see no difference in both JSON files which means scripts work correctly.
