## The VASSAL Engine

https://vassalengine.org

## Overview

VASSAL is a general-purpose engine for building online versions of traditional turn-based games. To play a game using VASSAL, you must first have a module for that game. Many modules are available for download on the VASSAL Modules page, although a module need not be hosted on the website to be playable.

## Quick Start

For an overview of VASSAL’s capabilities, select Help→Take the Tour, and step through the tour by hitting the Step Forward button.

To play a game, download a VASSAL module file to your computer. Select File→Open Module and choose the downloaded module. This will open a controls window for the game. Start a new game or load a saved game by using the File menu of the controls window. Some modules come with optional extensions, which can be downloaded separately. To enable an extension, right-click (Mac users: Command-click) on the module in the Module Library window, choose 'Add Extension' and select the downloaded extension.

You can also specify any number of directories containing saved games and load those games directly from the Module Library window.
From the Module Library’s File menu, you can edit any module or extension, or create new ones from scratch. You can also import modules created by Aide de Camp 2 (support for other formats is planned for the future).
Select Tools→Server Status to see what games are being played on the live server. To connect to the server, load a module and hit the Connect button. To chat with other players, double-click on the room with those players. To begin playing, one player must start a game from the File menu. The other player right-clicks on the first player’s name in the server controls and selects Synchronize.
VASSAL supports languages other than English. To change your preferred language, open any module, choose File→Preferences and select your language from the drop-down menu in the General tab. If your language is not listed, you can help provide a translation by selecting Tools→Translate VASSAL User Interface. Further details are given [here].
