Developing Addons

The following set of pages describes the process for developing addons for openBVE.

Basic Setup for creating a new addon:

In order to create openBVE addons, you should first download the openBVE Developer’s Tools :

Developer’s Tools 1.4.4 (2016-04-01)

This consists of two major tools- Object Viewer and Route Viewer , and two minor tools Train Editor and Object Bender

These should be extracted into your route openBVE folder, as they require data from the main download.

Route Viewer

Route Viewer allows you to render and view a route file. It supports viewing a route, reloading routes, visualising certain non-visual commands (such as Track.Section ), and jumping to stations and point of interest.

Object Viewer

Object Viewer allows you to view the 3D model formats which openBVE supports. It supports viewing multiple objects overlaid, reloading objects, and generates a list of errors in object files.

Train Editor

The Train Editor allows the editing of a train.dat file, including modifying properties and values, previewing train acceleration curves, and plotting of train sounds pitch and volume.

Object Bender

ObjectBender is a utility that helps create curved objects from shorter segments, for example, a 25m-long curved rail from a 5m rail segment.

ObjectBender offers a graphical user interface (GUI) as well as a command line interface (CLI). The GUI allows you to quickly create longer objects, while the command line interface helps with repetitive tasks.

The following is a list of command line arguments. Use these in a batch file to quickly create multiple objects that constantly needs updating(for example, multiple rails for different radiuses from a single rail segment.
