Sensor Glasses

To have the Sensor_Glasses detect additional ores, including ores from other mods, you — or the server owner if playing Multiplayer — will need to have set the additional ores in the under the Detectable IDs config like this (these are some vanilla ores, they can be removed if you like):

    # List blocks from other mods that the Sensor Glasses should recognize as solid blocks. Format is BlockName or BlockName:metadata.
    S:"External Detectable IDs" <
        16:0
        56:0
        14:0
        15:0
        21:0
        73:0
        74:0
     >

To set block names correctly there, follow the exact same procedure as described in SealableIDs. You only need to do that once.

This setting is done on your own Minecraft client in single player, but in multiplayer it will be overridden by the server settings. (That is done to prevent cheating, otherwise players could set the block IDs for chests, treasure chests or other desirable non-ore blocks…)

Here is an example of a config entry with detectable ores set up for Applied Energistics 2, Big Reactors, Biomes O’Plenty, IC2, Immersive Engineering, Railcraft, Thermal Foundation and Tinker’s Construct

Day-night cycle

Mars’s day-night cycle is synchronized with Overworld’s, and is therefore 20 minutes long, made up of 10 minutes of daylight and 10 minutes of night.

After sunset, the environment darkens but not as much as the Moon’s and hostile mobs will be able to spawn on surface. Since the sunrise and sunset of both planets happen at the same time, the best moment to travel to Mars is during the Overworld’s dawn (about 1.5 minutes before the sunrise), so that you have enough time to set up a quick base on Mars before the sunset.

Due to a bug in Galacticraft 2, the sun and stars were visible only on far-view distance. It is now fixed.

Mobs

Slimeling

Slimelings are tameable mobs found on Mars. Slimeling Eggs have a chance to spawn on the surface of Mars. They can be red, blue or yellow. They can be renamed and fed to create mini-slime bodyguards.

Sludgeling

Sludgelings are some kind of macro-bacteria that spawn in swarms in the Bacterial Sludge. They attack any mob, including the players. A Sludgeling swarm takes place when any mob touches or gets close enough to the bacterial sludge.

Boss

The Mars boss is the Evolved Creeper Boss, which can be found in the Mars dungeons. The boss is a three-headed giant Creeper that has an Oxygen Mask and shoots TNT at the player on sight.

Step Six: Building a Rocket

Reviewing steps completed so far: you’ve gathered ore and oil, created a power source (perhaps even solar power), crafted various machines for processing ore and filling both fuel and oxygen tanks, you’re wearing your spacesuit gear — or at least the oxygen-related components — since it’s always a good idea when leaving solid ground to carry a Parachute, add that too. The last slot on the spacesuit tab is for a Frequency Module — it’s optional, but will help you hear sounds properly while in space (it’s also used with the Telemetry Unit so that your buddies can keep track on you from your base, if you are playing with friends).

Every space program of course needs a rocket. It’s now time to get to work on that. First up, build the NASA Workbench — right click to view the Tier 1 Rocket layout. Insert the various components to make the rocket — nose cone, plating, fins and of course, the engine. Pro Tip: wooden chests are optional, but not expensive, so you should always add 3 wooden chests when crafting your rocket to give it the maximum cargo hold.

Build a launch pad and place your rocket on it and you’re almost ready for take-off!

Installing a Fuel Loader next to the launch pad enables the loading of fuel via canisters made in your Refinery. Other mods can also enable piping fuel directly, rather than using canisters. Click the Load Fuel button to start the fuelling process for your rocket. Enter your rocket and press «F» to not only view the fuel load percentage but also your inventory and — if you added chests during assembly — the inventory of the rocket itself.

Usage and functionality

An Oxygen needs at least three things before it becomes operational

• A sustainable oxygen supply.
• A capable power supply.
• An airtight room.

Connecting the sealer to a local source of air, as well as coupled to a power network will cause it to activate and intitiate a 5-second check of its surroundings. If there is no breach in the room, it is in, then it will successfuly seal, as indicated by the status, when you right click on it.

It is recommended to provide some storage for oxygen if you cannot sustain the oxygen supply for an extended period time.

What Oxygen Sealers do have is the ability to adjust the temperature to habitational levels which can relieve you of having to use thermal protection. This can be done by fitting a Ambient Thermal Controller into its slot. However, it may consume more energy in this way.

How to use

Read here for full information about how to make a sealed space.

«Special» types of blocks which are not normal solid blocks which you can place a torch on, might not be sealable unless you set it up in configs. This applies to nearly all see-through blocks except for vanilla Glass Blocks and Glass Panes. So most types of glass (for example Clear Glass from Tinker’s Construct) do not seal unless you edit the Galacticraft core/config file. (Some glass in other mods might seal if it is just a different version of vanilla Glass Blocks, for example Chisel 2 mod borderless glass should seal OK without you needing to change configs.)

Opening an Air Lock to go outside will expose that room to the planet’s environment, thereby sucking all of the air out of all rooms that are not sealed. This can be prevented by installing two air-locks to your base in tandem: one exterior door that goes directly outside and one interior door with a small room in between both air locks. This will create a sort of air lock chamber so that there is never a direct opening to the outside.

Glass panes in the wall can seal OK — see Figure 1. Glass panes in the roof or floor have holes in them, so they do not seal — see Figure 3. Wool including carpets, Sponge, Leaves and Gravel can never make seals. A Farmland Block in your roof can seal (it has a solid dirt underside) but not in the walls — there is a slight hole at the top which the air can escape through.

In the case of sealing larger rooms, a single oxygen sealer may not be able to seal it on its own. Thus multiple oxygen sealers may have to be used instead.

Figure 1: Glass panes in the walls can make good seals.

Figure 2: The room has gone from sealed to unsealed.

Figure 3: Glass panes in the ceiling have holes and do not make good seals.

Step Three: Crafting Machines

Galacticraft has quite a number of machines — usually the size of a crafting table — that perform some amazing functions. This part of the tutorial covers the basic machines you need to start off with.

Although the orientation of a simple crafting table doesn’t matter much, the machines you create using Galacticraft have some unique sides to them. Some might require power input on a particular side, some might produce oxygen on another side, and so on. Many of the machines need electricity to power up, though a couple of them are powered using coal.

Like regular Furnaces and Crafting Tables, usually right-clicking on the machine will let you view its console. Moving your mouse over the slots in the machine’s console will give you some information about what each part does, and what materials go where.

Circuit Fabricator

The first machine that you will want to build is the Circuit Fabricator, since it creates the Basic Wafer and Advanced Wafer which are essential components used in many of the other machines. (It also creates Solar Panels which you will use later to make solar power.)

Side Note (Galacticraft 2 only): If you power a Circuit Fabricator via a Buildcraft kinesis pipe network, we recommend using an iron kinesis pipe to limit the power that it draws. It works fine on an iron pipe at the lowest 2 MJ setting, but connected directly to a high-power pipe network, it can draw all available power.

Compressor

Now that you are able to create a Basic Wafer, the next machine to build is a Compressor, which compacts ingots into more durable, compressed versions of the material. The Compressor runs on coal, or other combustibles. Later you will be able to make an Electric Compressor that runs from a power source instead, but since it requires compressed materials to build, you need to make the coal-fired one first.

Introduction

Building rockets, space stations and colonies on new worlds may seem a little overwhelming, if you’re just starting out. So here is a small guide to getting started with Galacticraft!

Quick Start

Before you head into space, you will need a few items including the Tier 1 Rocket, Rocket Launch Pad, Fuel Loader, Fuel Canister, Oxygen Gear, Oxygen Mask, Oxygen Compressor, Oxygen Tanks, Parachute.

Later, for a proper scientific look (once you have obtained the basic items from a Circuit Fabricator and a Compressor), you can power your base using Basic or Advanced Solar Panels which track the movement of the sun.

The NASA Workbench and Refinery are needed to create your rocket and make the fuel for it. You will also need plenty of raw materials: a stack or more of iron ore, copper ore, tin ore, aluminum ore, and some silicon.

Additionally, you can make a Display Screen to place in your control room, which shows some of the planets and other interesting information.

Life Support and a Parachute

If you don’t take oxygen equipment with you into space, you will die. The four most crucial items you will need are the Oxygen Gear and Oxygen Mask and Oxygen Tank, and a Parachute of course. Once you have this equipment, you are almost ready.

Launch Your Ship

You will need to make the Rocket Launch Pad and Tier 1 Rocket, of course. Make the rocket in the NASA Workbench.

Place the nine rocket launch pads you have on the ground in a 3×3 square shape, so they join up to make a launch pad. Place your rocket on top of them. You will then place a Fuel Loader directly adjacent on any side of the launch pad. You are all but ready. You will of course need some Fuel to put in the Fuel Loader. If you haven’t found any oil yet, go ahead and get some, which generates deep in the ground around the gold ore level. Use a Portable Oil Extractor to place the oil into canisters, take those Oil Canisters to your Refinery and start converting the crude oil to Rocket Fuel. Place the Fuel Canisters in the Fuel Loader and click the load fuel button to have it fuel your rocket.

You can now go to the Moon! All you have to do is equip your Parachute and Oxygen Gear and mask, climb in your rocket, and hit Launch. If you want to be able to come back again, it’s also essential that you take a Fuel Loader with you, also a couple of charged batteries or something else to power it with and an Empty Canister, a spare Fuel Canister would also be wise just in case.

Once you reach the Moon, you can finally explore the lunar surface for Moon Village(s) or even the prized Moon Dungeon. For a longer stay, build a .

Next stop, Mars!

Warning

Constant updates between sealing and unsealing

If your sealer setup has «only just» enough oxygen or «only just» enough power to keep the sealers running, then probably some of the time some of the sealers will run out of oxygen or power — in which case obviously they will stop working! If a sealer stops working, then maybe your space will become unsealed. When it becomes unsealed, the sealers stop using so much oxygen, which maybe gives your system enough for all the sealers to start working again and re-seal the space. This is not a good arrangement. It can make for LAG on a server because switching a large room between sealed and unsealed is a lot of work for a server.

It’s up to players to make sure that any build with sealers has enough power and oxygen that it works properly. For the future, the developers are looking at ways to penalise builds which do not do this correctly, for example by having the sealers self-disable for a while.

Chunk loading issues

Sealers can only work properly if they, and the power and oxygen systems which feed them, are properly chunk-loaded — meaning inside the «active chunks» radius (see above: normally on servers the active chunks radius is 32 blocks less than the chunk loading view radius).

Some players route their oxygen and power for sealers around the edge of their bases, meaning that the crucial oxygen pipes or power conduits could be on the far side from the player (so maybe not chunk loaded all the time?).

Some other mods power systems are not as well-coded as Galacticraft and do not perform robustly and sensibly when chunks are loaded in a random order. Be especially wary if you are using sealers with power systems from other mods.

A great way to test whether chunk loading issues are affecting your build is to place Infinite Oxygen and Infinite Battery items in every Oxygen Sealer. Test whether the space stays sealed properly as you move around, and leave the area and return. If it does, then the sealers themselves are working properly and it is your power or oxygen delivery systems which need work.

Step One: Gathering Resources

Overworld Ores

The first thing is to gather Tin Ore, Copper Ore, and Aluminum Ore (which can be smelted into Tin Ingots, Copper Ingots, and Aluminum Ingots respectively). You will also want to find some Silicon Ore, which is rarer than the other three ores and forms at deeper levels (drops Raw Silicon when mined).

Oil

If Galacticraft is the only mod that you have installed, you can gather oil using either regular buckets, or Empty Canisters and a Portable Oil Extractor — we’ll get to these in a minute.

If you have Buildcraft installed, the recommended method for gathering oil is by using a pump and Buildcraft or Railcraft tanks. Buildcraft also has the ability to gather oil in buckets. Forestry gives you the option of using tin cans, which are cheap, but single-use. Or, you can wait until we’ve created the Galacticraft tools necessary for oil collection.

Potion effect error

Explanation: this is a crash caused by another mod not registering a potion effect properly. A «potion effect» can be any bad stuff that happens when you take damage from a mob, like poison, dizziness etc. To find the cause, take a look at your mods which have mobs which do extra damage effects like that.

Step Five: Collecting Oxygen

Eventually, you will be able to create oxygen while in space. But your first time up, it’s a rather crucial resource to bring with you!

Oxygen Collector

First, you will need to create an Oxygen Collector, which likewise requires power to run. In the Overworld, you can place it anywhere to begin gathering oxygen.

In space or a no-atmosphere environment, you would need to surround the Oxygen Collector either with leaves or growing wheat. But in the Overworld, you can place it anywhere, it just takes oxygen out of the air.

Oxygen Pipe

In order to do anything with the oxygen collected by the collector, you will need to create Oxygen Pipes using six panes of glass on the regular crafting grid — three across the top and bottom.

You will use the Oxygen Pipe to feed the Oxygen from the Oxygen Collector to the…

Oxygen Tanks

You will use the Oxygen Compressor to fill Oxygen Tanks. There are three sizes of oxygen tank that you can build — the Light Oxygen Tank, the Medium Oxygen Tank, or the Heavy Oxygen Tank. In order to have ample time to start your moon base, bringing multiple medium or heavy tanks is recommended. For detailed information on oxygen tanks as well as how to put on your spacesuit, head over to the Oxygen Tutorial page.

Galacticraft mob seen on Overworld

When your game is working properly, there will not be any Galacticraft mobs spawning naturally on the Overworld.

Occasionally, players report issues like this:

It could be the Evolved Creeper Boss seen on the Overworld as there, it could be some other Galacticraft mob.

This phenomenon happens when the player is on a server and the server has different mods (or different mod versions), or maybe just different configs for something connected with Entity IDs. It’s not Galacticraft causing this. One of your other mods is different.

The Galacticraft mob is not really there — it just looks that way, in reality it’s a chicken or a sheep or something. It won’t attack you.

How to fix:

This can be fixed simply by updating to the latest Galacticraft (versions 3.0.12.425 or later) on the server and on the client, note both need to update together. However, this fix might just transfer the problem to some other mod instead, in which case read on.

If that doesn’t solve it — if you need to stick with an older Galacticraft version for some reason, or now the same problem is happening for a different mod’s mobs — then:

Carefully check that the player does not have a mod which is missing on the server — this is the most likely reason. (Except: mods like Optifine or mapping mods are client-side only, so don’t worry about those ones.)

Carefully check the whole modlist to make sure every mod has exactly matching versions between server and client

If all the mod versions exactly match and the issue still happens, now check that all the configs exactly match

If there’s still a problem then most likely you did not check those things carefully enough. Either that, or it’s a bug in one of the other mods (very unlikely as any bug like this would have been spotted within minutes)

Oxygen

«Oxygen» in Galacticraft can mean either breathable Oxygen, or pure (industrially-made) .

A range of machines in Galacticraft handle breathable Oxygen so that players can breathe in a space environment. An Oxygen Collector collects oxygen, Oxygen Pipes pipe it to other machines, an Oxygen Storage Module can be used to store it.

The oxygen can be used in:

• Oxygen Compressor — used for filling player oxygen tanks
• Oxygen Distributor — used for making a bubble of breathable air in an unsealed space
• Oxygen Sealer — used to fill a Sealed Space with breathable air.

Oxygen cannot be transferred from the Oxygen Collector or Oxygen Storage Module to other mods — only Galacticraft can use this oxygen, and only Galacticraft’s own oxygen pipes can transport it.

Trivia

In the early US space program (Mercury, Gemini and Apollo missions), space suits supplied astronauts with pure oxygen for breathing. The oxygen was at low pressure, around 1/5 of atmospheric pressure, to match the partial pressure of oxygen in earth’s standard atmosphere but without the other atmospheric gases like nitrogen. This meant the missions did not have to carry the extra weight of nitrogen tanks, but it was also dangerous, as pure oxygen increases the fire risk.

The Russian space program has always used a mixture of nitrogen and oxygen for breathing purposes.

Galacticraft 3

Galacticraft 3 introduces oxygen made by industrial processes. It can be made either by electrolysing water in the Water Electrolyzer, or simply by feeding air on the Overworld (or any other planet with oxygen as a major atmospheric component) into a liquefaction plant, the Gas Liquefier.

Uses:

• oxygen can be made into in the Gas Liquefier
• oxygen can be piped through Oxygen Pipes into the Oxygen Storage Module, Oxygen Compressor, Oxygen Distributor or Oxygen Sealer and used for breathing
• oxygen from the Water Electrolyzer can be used by any other industrial mod which has a use for a Forge fluid named oxygen

The dimensions

The Overworld

Overworld landscape

Main article: Overworld

This one you know all about already. This is the old and good earthly-like dimension where the game always starts.

Here is where you will spend your first period of time in the game gathering resources to built your first rocket, your life support equipment and other essential items to start your travels in space. Don’t forget to check the Pre-flight Checklist.

By the way, did you know that you can make your own Space Station to orbit it?

Moon

Moon landscape

Main article: Moon

The Moon is made of Moon Rock with traces of cheese. Its surface is covered in craters from aeons of impacts by meteors.

It is reachable with a Tier 1 Rocket.

Some things to do on the Moon:

• land in a good spot in your Lunar Lander
• plant a Flag
• admire the Overworld in the night sky
• practise bounding in low gravity
• plant trees and get an Oxygen system running
• taunt some Evolved Spiders (be warned, they’re faster than regular spiders)
• make a Moon base
• find an Alien Village
• mine some Meteoric Iron
• kill the Moon Boss
• open the Tier 1 Treasure Chest
• make a Moon Buggy

Meteoric Iron is used to make several things including the Arc Lamp, the brightest light source in Minecraft!

Pro Tip: To travel between a Moon base and an Overworld base, make a rocket pad at each base and set up a Launch Controller on each pad. Now you can launch and land in the same rocket — it’s faster than using a Lander each time. You will have to think about refuelling arrangements of course.

Mars

Mars landscape

Main article: Mars

Mars is made of various kinds of red rock. The atmosphere is a dusty orange color, and the sun is a little dimmer than on the Overworld. It gets very cold at night, so make sure to wear Thermal Padding.

Mars is reachable with a Tier 2 Rocket.

If you spend some time on the surface, you will likely come across some Slimeling Eggs. Break them to hatch a friendly little critter which makes an excellent pet. You can grow it into a strong fighter; fit it with a bag and it will carry stuff for you; and adult slimelings can breed to make babies of new colors.

But the real wealth of Mars is underground. Here you will find:

• a variety of ores
• a new material, Desh which is used to craft some of the more powerful items in Galacticraft
• underground caverns with Bacterial Sludge, Sludgelings and Cavernous Vines
• the Mars Dungeon with the fearsome Evolved Creeper Boss
• Tier 2 Treasure Chest items include the Tier 3 Rocket Schematic, the Cargo Rocket Schematic and (as of version 3.0.12) the Astro Miner Schematic

Armor made from Desh has a unique knockback reduction ability — very useful in a fight!

Pro Tip: Mars is a great place to set up an automatic fuel production factory, using the Methane Synthesizer and Gas Liquefier.

Asteroids

Asteroids view

Main article: Asteroids

The Asteroids is a very different kind of dimension, filled with large and small asteroids. There is microgravity so you will need to figure out a safe way to move between them, or risk an endless fall!

You will need a Tier 3 Rocket to reach the Asteroids. It’s a little further from the sun so there’s not so much light as you are maybe used to: it’s a good idea to bring a powerful light source with you. It’s also cold in deep space: Thermal Padding is essential.

If you spend some time in the Asteroids dimension, you will discover that it’s a miner’s paradise. Around one third of the asteroids have a of mineable minerals. This includes a new ore, Ilmenite — you can make Titanium from it.

The Astro Miner can automate your asteroid mining: it automatically finds nearby asteroids, flies to them, mines out their cores, and brings back what it finds to its base.

Titanium is used to make the Titanium Sword, the most powerful weapon in Galacticraft, and also the Short Range Telepad, Beam Receivers and Beam Reflectors, and Walkways.

Pro Tip: The Grapple can help you move around this dimension. Once you get some Titanium you can make Short Range Telepads to travel between two Asteroid bases.

Venus

Venus landscape

Main article: Venus

Venus is the 4th and latest dimension to be added in Galacticraft 4. It is a Nether-like place with steep mountains, vapor, lava and lots of dangers.

The sky is very cloudy with constant lightning storm. There’s no rain or snowfall. The atmosphere is very poisonous and corrosive. The days are very long: about 10 hours (30 Overworld days). To generate energy, use Geothermal Generators.

The landscape offers a variety of terrain formations and biomes with tall and sharp mountains, plains and valleys with lava pools. Watch out for Sulphuric Acid pockets.

Featuring:

• Crashed Probes.
• Spider Queen, as boss, and ‘Juicers’, as her minions.
• Volcanic Pickaxe and Shield Controller as rewards for beating the boss.
• Galena ore (yeld lead).

Mod conflicts: Binary Seach method

So you have this huge modlist of 50 or more mods, and one of them is conflicting with Galacticraft, but it’s not obvious which one. How do you figure that out, without restarting the game 50 times?

A binary search method can find which mod is conflicting in just 6 restarts of the game.

The concept is you divide your modlist in half — remove half of the mods — then see if the game still has the issue. If the game still has the issue, then you know the problem is in the half of the mods you kept. If the issue stopped happening, then you know the problem is in the half of the mods you removed.

Steps:

Step 1. create a new folder /mods_removed and move half the mods from the /mods folder to it (keep together mods which have to go together, for example some mods have to be paired with core mods or libraries like Mantle)

Step 2. make a note or screenshot of the mods you just moved, because you will need to know later which is which — or maybe make subfolders in the /mods_removed folder so you know which group is which;

Step 3. start the game, create a new world, see if you stil have the issue or not;

Step 4A. if the issue was fixed, look at the mods you just removed, pick half of them and move that half back into the /mods folder, keeping a careful note of which mods these are, then go to Step 3;

Step 4B. if the issue was not fixed, pick half of the remaining mods (or half of the ones most recently added back in at Step 4A) for removal, and go to Step 1

Obviously you must not use an existing world before doing these tests, because changing mods around will damage any existing world. If you have to have an existing world because you need a complex build, keep a full backup.
