[Terasology Launcher][github terasologylauncher] is the official launcher for the open source game [Terasology][github terasology]. It provides easy access to the different game versions and build types. Terasology and related projects are developed by a group of software enthusiast volunteers under the organization name [MovingBlocks][github movingblocks].


If you want to get in contact with the Terasology community and the whole MovingBlocks team, you can easily connect with us, share your ideas, report and solve problems. We are present in nearly the complete round-up of social networks. Follow/friend us wherever you want, chat with us and tell the world.




  1. Download the corresponding archive for your platform from the latest release
  2. Extract the archive to the path where the launcher should be installed
  3. Start Terasology Launcher
Operating System Executable
Windows TerasologyLauncher.exe or bin/TerasologyLauncher.bat
Unix, Linux, Mac OS X bin/TerasologyLauncher


On first start-up, the Terasology Launcher will prompt you with the selection of the Terasology installation and data directories. The installation directory is the application directory of Terasology and contains downloaded and extracted game packages. The data directory is the place for configuration data and user-specific files such as key bindings and save games. Note, that these directories are different from the launcher installation directory, which is the folder you extracted the launcher archive to.

Terasology Launcher UI

The Terasology Launcher UI provides functionality to download, start, and delete different game versions. The game versions are grouped by the type of build they belong to:

Build Type Explanation
Terasology Released version of Terasology core game bundled with modules
Terasology (nightly) Development build of Terasology core game bundled with modules
Terasology Lite Released version of Terasology core game only
Terasology Lite (nightly) Development build of Terasology core game only

In addition to this main functionality, the UI displays information about new changes of the selected game version ("Changelog"), launcher information concerning changes, licensing and contribution guidelines ("About"), and logging data for the current launcher execution. Further, you have access to the social media representation of Terasology.

Terasology Launcher Settings UI

The settings view enables you to open the launcher installation, game installation and data directories for quick access and edit the data directory in case you want to change it after setting up the launcher. You can configure the memory settings for the game and even specify additional java or game arguments as well as the logging level for the game. Please note, that the "Initial Game Memory" and "Maximum Game Memory" setttings only apply to the game itself. The actual resource consumption may be higher due to additional resources required by the Java Virtual Machine (JVM).

The remaining settings can be used to configure the launcher. You can set the launcher language and decide whether the launcher should search for updates, close when a game is started and save downloaded game package files.


To be able to run TerasologyLauncher from source follow these steps. This guide is designed for IntelliJ IDEA (you can use the free community edition), but alternative setups are possible.

:octocat: Get Ready

To contribute to this repo, please open a [pull request][github forking] from your fork of this repository.

For more information on building and developing the Terasology Launcher, make sure to read the rest of this README and [][contributing].


You'll need the following tools:

  • Java SE Development Kit (JDK) 8 with JavaFX. It may be possible to use a later version of the JDK for local development, but the CI will verify against this baseline version.
  • Git to clone the repo and commit changes.

Development is possible on all common platforms (Windows, Linux, MacOS) as long as the JDK with JavaFX is properly set up.

:nerd_face: Start developing

Familiarise yourself with Git's concept of repositories, branches, and commits. To get the latest changes from your remote repositories (e.g. movingblocks) you need to fetch all remote data via git fetch --all. This does not change your workspace, it just loads up your local Git database.

Apart from Git, basically everything can be done using the [Gradle][gradle] [wrapper][gradle wrapper]. The following list is an excerpt of some commonly used tasks.

Command Description
gradlew build Compile the source code, run tests and build a JAR.
gradlew install Create a local runnable installation (placed in ./build/install/TerasologyLauncher).
gradlew run Build and run the launcher.
gradlew createRelease Create a local development release (located in ./build/distributions).
gradlew tasks Display other available build script tasks.

Assume you have pushed some changes to your fork into a branch myFeature. In order to let us know about your work and give us the possibility to incorporate your changes you should send us a pull request. You can do this by selecting the myFeature branch on your GitHub repo and click the button which says "Open pull request".
