Terasology is a game that pays ample tribute to Minecraft in initial look and origin, but stakes out its own niche by aiming for the NPC-helper and caretaker focus from such games as Dwarf Fortress and Dungeon Keeper, while striving for added depth and sophistication.

Terasology is an open source project started by Benjamin "begla" Glatzel to research procedural terrain generation and efficient rendering techniques in Java using the LWJGL. The engine uses a block-based voxel-like approach as seen in Minecraft.

The creators of Terasology are a diverse mix of software developers, game testers, graphic artists, and musicians. Get involved by checking out our Community Portal, our blog Moving Blocks!, and our Facebook Page.

Terasology is licensed under the Apache 2.0 License and available in source code form at GitHub.

Terasology requires Java 7, the newer the better - download it here. Also make sure that your graphics card driver is up to date.

For easy setup (recommended) you can use our launcher - download it here

For direct downloads you can get the latest stable version here or our cutting-edge develop version here from our Jenkins

You can use the Windows executable or one of the default launch scripts to start the game. They will setup your Java Virtual Machine to allocate up to 1024 MB of memory. Under Linux and Mac OS X the run script needs the access permission "Execute" to run properly: "chmod +x [scriptname].sh".

To name yourself for a multiplayer game use Settings / Player

More or completely alternative line-ups with certain modules / world types selected

Press the grave key (usually the ` key immediately above tab) to show the in-game console. Block names and some other things are not capital sensitive while command names are. Copy paste is supported and up/down arrow will cycle through commands you've used before. Hitting tab with a partially typed command will auto-complete it (including abbreviated camel case like lS for listShapes). For partial commands with multiple completion candidates you can tab again to cycle through them.

• help - Show in-game help (more thorough)
• flight - just what it sounds like :)
• ghost - no-clip mode (fly through anything)
• hspeed - greatly increase your movement speed
• hjump - jump really high. Almost like flying - but it isn't. Just jump good.
• restoreSpeed - normalizes speed (both horizontal and vertical)
• help "giveBlock" - Shows detailed help on the "giveBlock" command
• giveBlock "Water" - Gives 16 water blocks
• giveBlock "Stone" "Stair" 99 - Gives you 99 stone stair blocks
• giveBlock "Chest" - Gives you a Chest block you can place, activate ('E'), put stuff in, break, pick up, place elsewhere, find same stuff in it!
• giveBlock "TNT" - Gives you 16 TNT blocks you can place and activate ('E') to blow up
• listBlocks - Lists all actively used blocks (have been loaded for the world)
• listFreeShapeBlocks - Lists all blocks that can be requested in any known shape
• listShapes - Lists the available shapes
• teleport 42 42 42 - Warps the player to x = 42, y = 42, z = 42
• fullHealth - Fully restores the player's health

Run any commands in the project root directory

• Download / clone the source from GitHub
• To prepare for IntelliJ run: gradlew idea
• To prepare for Eclipse run: gradlew eclipse
• To run from the command line: gradlew run
• Start a headless server: gradlew start (stores data in /terasology-server - the Gradle command blocks until server is killed)
• For more tasks: gradlew tasks

You may also need to tweak IDE settings further for your convenience, in particular for Eclipse. See Dev Setup in our wiki for more details.

Note that by default stored data (config, saves, etc) is sent to a user profile directory like Saved Games under Windows. Add -homedir to a run configuration or command line execution to use the project dir instead (this is done automatically in some cases including IntelliJ and gradlew run)

If you want to pull down the source code for a module you can easily do so via Gradle:

• gradlew fetchModuleSample
• gradlew idea

This fetches the module source for the "Sample" module and the second command fetches any dependencies and updates the IntelliJ project structure so you can see it as a module. Likewise for Eclipse or any other setup you should run any one gradlew command to make sure the new module's dependencies have been fetched as well. See Codebase Structure in the wiki for more.

Content, gameplay mechanics, and mostly everything other than the engine that allows the game to run is stored in what we call "modules" which are similar to the traditional meaning of "mods" but intended to be smaller building blocks you'd normally put several of together to make one traditional "mod".

Modules must be enabled during world creation by selecting them using the "Modules" button. Some world generator types may be registered by a module and auto-select that and maybe other modules if you choose that world type. Modules may also enable additional console commands (listed by the "help" command when active).

As opposed to engine level projects listed under https://github.com/MovingBlocks all modules are listed under a different GitHub organization at https://github.com/Terasology

Here's a list of modules bundled with the game by default (as of this writing anyway - this line-up will change now and then). It should roughly match this category in Jenkins: http://jenkins.movingblocks.net/view/Modules and you can download updated modules from there if needed.

• AlterationEffects - module for storing some buff/debuff type effects
• AnotherWorld - world gen module, includes features like ore placement and caves, used by WoodAndStone's world
• BlockNetwork - a framework to support blocks that can communicate with each other in some fashion
• BlockPicker - allows the player access to an infinite block inventory with the B key
• Breathing - without this you can't breathe! But you also don't need to. Enable it to drown properly in water (or not!)
• CakeLie - the cake may be a lie, but these cake and candy blocks are delicious!
• Caves - a cave generation module (actually an ore vein generator placing air veins!) based on CustomOreGen
• ChangingBlocks - allows blocks that change over time (like crops that grow - which will happen if you also enable Crops)
• Cities - procedural city placer and plot organizer, also places roads to connect cities
• CommonWorld - general world generation utility module
• CopperAndBronze - another era for throughout the ages, this time copper and bronze (comes after wood and stone)
• Core - mandatory content needed for normal game launch
• Crops - a series of crop-like plants with multiple growth stages

• Fences - fences!
• Fluid - adds support for fluid in non-world situations (such as for storage in workstations)
• FunnyBlocks - cheese wheels and bowling pins - why not
• Genome - genetics WOO! Complete with DNA letters and mutating plants. Part of the Wood & Stone line-up
• GrowingFlora - organically growing (step by step) trees and such
• Hunger - makes the player slowly gets hungry (needs actual GUI work and ways to then actually eat food though). Console hungerCheck for stats
• Journal - allows the player to use an in-game journal for gameplay notifications and such. Default toggle key 'J'
• LightAndShadow - main module for the Light & Shadow gameplay
• LightAndShadowResources - IMMA FIRIN’ MAH LASR!! Art assets for the Light & Shadow concept
• Machines - machine infrastructure library module

• Minerals - a large collection of mineral blocks
• Miniion - base creature control system, used by MasterOfOreon - old module that has gone through a few redesigns
• Minimap - a basic minimap using "slicing" (showing a single layer at a time as per a selected axis). Show/hide with 'M' by default
• MoreLights - assorted illuminated blocks
• MultiBlock - supports the concept of multiple blocks being part of the same structure
• NameGenerator - can create random themed names for use by other modules, or via console using commands like generateNameList 10
• OreGeneration - ore generation plugin system based on CustomOreGen (this one enables easy definition of what ores you want in a world)

• PlantPack - more plants! Used by the Wood and Stone gameplay
• Portals - allows placement of portal blocks that'll spawn Oreons giveBlock "portal"
• Rails - Railroads and trains! Press 'e' to start a caboose or enter a cart. Use the wrench to attach carts
• Sample - miscellaneous example content showcasing module usage
• Signalling - circuitry implementation based on BlockNetwork, similar to redstone
• Soils - a small pack of different soil types
• Spawning - split out from Portals to serve as general utility for anything needing stuff to spawn
• StructuralResources - a set of structural shapes suitable for buildings and such
• TerraTech - Machines to improve your life (the "Terra" is for Earth, not short for Terasology)
• WoodAndStone - big gameplay module featuring "from scratch" crafting throughout the ages - wood here
• Workstation - workstations offer a way to use blocks in-world for advanced purposes
• Zones - allows you to define zones within the world, that other modules can then use for assorted reasons
