Micdoodlecore 1.8.9/1.7.10 (library for galacticraft mod)

What Next?

There are tons of great things you can try out in Galacticraft, and more are being added all the time!

Here’s a short list of things to try out:

• Construct an Overworld Space Station and invite your friends.
• Explore the Moon and make contact with a colony of Moon Villagers.
• Make your mark, by placing a Flag on the Moon or try it on the Overworld.
• Mine up some Cheese Ore.
• Establish an oxygen supply system on your Space Station, or Moon Colony.
• Make a Moon Buggy and drive around in it.
• Mine some Meteoric Iron and build Spin Thrusters to have your Space Station spin
• Build a more technological looking base, with Arc Lamps for illumination (this is the brightest light source available in Minecraft) and Display Screens on the walls
• Continue on to Mars.
• Mars unlocks a new material, Desh which will let you make better armour and tools and some other more powerful items
• Mars also unlocks new machines, and access to the Asteroids …

This How To guide can give you some more ideas for what is truly possible in Galacticraft…

Working with other mods

In Galacticraft 3 and Galacticraft 4 (and the final releases of Galacticraft 2), blocks from other mods should mostly be automatically detected whether they are sealed or unsealed.

For some special types of block, Galacticraft may ‘think’ they are not sealed, when in fact you want them to be sealed. The most common example is new types of glass from other mods — for example, Clear Glass from Tinker’s Construct. Unless set correctly as a sealable block in the config (see below) a base made out of Clear Glass will not be able to seal.

So if a space is not sealing and you think it should be, check whether you are using any special blocks from other mods. (Any block which you cannot place a torch onto, might be a ‘special’ block.)

Galacticraft’s config allows you to add the block IDs of any special blocks — for example Clear Glass or Hardened Glass from other mods which should be sealed. Players (or server owners) with other mods will need to add the block IDs for these blocks to the config: here’s how. But blocks from other mods which are made out of leaves, gravel, sponge or wool can never be sealed!

Commands available to all players

gcenergyunits

/gcenergyunits <unit> — changes the units used by Galacticraft to show how much energy something has or uses. The available units will depend on which other mods you have installed. Possible choices are:

• gJ (Galacticraft Joules)
• RF (Redstone Flux)
• EU (EU — only if IC2 is installed)
• MJ (Minecraft Joules — only if BuildCraft or EnderIO 2.0 is installed)
• J (Mekanism Joules — only if Mekanism is installed)

gchouston

/gchouston — available in Galacticraft 4 only — rescues a player who is stuck on the Moon, or another planet or space dimension. It teleports the player back home to his bed on the Overworld (or to Overworld spawn if the player currently has no bed). Of course this is a one-way transfer, the player would need to build another rocket on the Overworld to return to space. The command must be typed twice to confirm that the player really wants to do this. (12 second timer)

If the game detects that a player is in a dying loop on the Moon or another planet, it will prompt for this command in chat. The player does not have to use the command but he can choose — if he uses it, there can be a chat sequence like this.

Uh, Houston, we've had a problem.... (Type /gchouston to abandon mission and return home.)
/gchouston
This is Mission Control, say again please? (To abandon mission, type /gchouston again to confirm.)
/gchouston
OK, stand by, <name>, teleporting to Overworld home position.

Electrical power

For default power configs see .

Galacticraft 3 and Galacticraft 4 are 100% compatible with RF mods and with every other major power system in modded Minecraft. This means you can use Galacticraft wires and Energy Storage Modules as an easy way to convert power between two other mods which can’t connect directly.

(Galacticraft has a long history of energy compatibility, arising out of our participation in the original ‘Universal Electricity’ project. The Universal Electricity project was abandoned but Galacticraft kept the best parts from it and improved on them. Galacticraft now has the highest performance and most compatible energy system in modded Minecraft — tested by forum members in comparison tests between same-sized energy grids from different mods including EnderIO and others.)

(Except Gregtech. We’re not compatible with Gregtech’s electricity, because Gregtech made it so that other mods can’t be compatible with their systems. Gregtech think all the other mods make electricity too easy … )

Non-fixable issues

These will need to be fixed by the authors of the other mods.

More Player Models

We cannot offer compatibility with this mod, as it uses an approach which is not really compatible with other mods. You may have improved results if you install Player API and Render Player API, try it and see.

Too Much Time

This mod’s dimension handling will cause crashes whenever you travel to a Galacticraft dimension, so basically Galacticraft is unplayable if you have Too Much Time installed.

Shaders Mod

Karyonix GLSL Shaders Mod is currently unsupported; the sky will not look good on Galacticraft planets or space environments. Best would be if that mod can auto-disable itself in Galacticraft dimensions.

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).

Liquid Oxygen

Liquid Oxygen is a cryogenic (extremely cold) liquid form of . It is a useful way of transporting Oxygen in a compact form. It can be transported in special canisters, or in fluid pipes from other mods. It is not intended that it can be transported in buckets!

If Liquid Oxygen is placed in a normal oxygen-using machine like an Oxygen Sealer or Oxygen Storage Module, the liquefied oxygen turns back into a gas. 1 bucket (1000 mB) of Liquid Oxygen can make 5,555 units of .

Using the Liquid Oxygen Canister, Liquid Oxygen can also be used to refill player oxygen tanks in an emergency.

Trivia

• In real life, Liquid Oxygen is transported in special flasks used for handling super-cold liquids.
• At -183 °C it will be a constantly boiling liquid, whenever exposed to normal room temperatures. It boils rapidly because, to the Liquid Oxygen, room temperature (25 °C) is a very hot temperature, well above its boiling point. When it boils it becomes oxygen gas.
• Because it is pure oxygen, Liquid Oxygen is extremely dangerous used near to any sparks or naked flames: any flammable object will burn almost instantly in pure oxygen (especially if it is dunked in liquid oxygen!)
• In the aeronautics and space industries, Liquid Oxygen is often known as LOX

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

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.

Silicon compatibility with other mods

Galacticraft consumes a lot of silicon, it’s needed in the Circuit Fabricator. Silicon Ore is hard to find, but if you mine it with a Fortune III pick you can get plenty of silicon from a good mining expedition.

Galacticraft 3 offers compatibility with other mods’ versions of silicon — for example, EnderIO can extract small amounts of silicon out of sand or clay, using the SAG Mill. If silicon from other mods is in the Ore Dictionary, then Galacticraft’s Circuit Fabricator can use it. But you have to set in Galacticraft’s core config what the OreDict name of the silicon in the other mod is, because there are a few different names can be used. The default is which is used by EnderIO and several other mods. Other tech mods — for example MineChem or GregTech — may have different versions, with different OreDict names like «plateSilicon», which are harder to make but maybe more suitable for Galacticraft as more of an end-game mod.

To disable Galacticraft from being able to use other mods’ silicon, just change «itemSilicon» in Galacticraft’s config to a word which can’t be in the Ore Dictionary, like your cat’s name.

If you want to make for a very hard game, you can even disable Galacticraft Silicon Ore from generating in the world, so there will be no Galacticraft silicon. If you then set an advanced item from some other mod as the OreDict name of silicon which Galacticraft must use, that could make it so even something as simple as a Galacticraft solar panel is a very late game item.

Full Guide

Before we begin: Mod Compatibility Notes

Some quick points that you will be interested in if you are using Galacticraft in conjunction with other mods. For full notes on compatibility see Compatibility.

Power Sources

Some Galacticraft machines need power to function. This can be provided in the form of:

• Galacticraft energy (from the Coal Generator, Basic Solar Panel, or Advanced Solar Panel)
• RF (Redstone Flux) (requires Thermal Expansion in Galacticraft 2 — Galacticraft 3 and Galacticraft 4 work with all RF mods)
• Mekanism J (Joules)
• IC2 EU (Energy Units)
• Buildcraft MJ (Minecraft Joules)
• Universal Electricity’s UE units (Galacticraft 1 only)

Ore Dictionary

Galacticraft’s ores and fluids are registered with the ore dictionary, thus making them compatible with most other mods. For example, Galacticraft Copper Ingots and Tin Ingots are interchangeable with: Mekanism, IC2, Tinker’s Construct, Thermal Expansion or Forestry copper and tin. Galacticraft Oil and Rocket Fuel are interchangeable with Buildcraft oil and fuel. EnderIO Rocket Fuel Buckets can also be used in your Fuel Loader.

Aluminum Ore can be powdered in Thermal Expansion’s Pulverizer. From version 139 (February 2018), Galacticraft 4 also lets Aluminum Ore be ground in a Grindstone from Applied Energistics 2 or it can be macerated in an IC2 Macerator (and then processed further in IC2 by ore washing and thermal centrifuge).

Creation

Standard Space Station with Sealing Station

To create a space station, fly your Tier 1 or Tier 2 Rocket to space. You will then be given the option to create a space station in the Planet Selection Screen so long as you have the required materials in your inventory (required materials listed below).

The components below will assemble a basic space station comprised of a small main room with the roof and corners built, a platform where you can place a Rocket Launch Pad, and a Parachest containing your rocket and a small amount of left-over fuel that can be collected using an Empty Liquid Canister. The station does not have any sort of oxygen or other life support so you should prepare accordingly.

Some recommended supplies include:

• Oxygen Mask, Oxygen Gear, and Oxygen Tanks
• Food and Building Materials
• Oxygen Collectors, Oxygen Distributors, and Oxygen Compressors
• Trees, wheat, or other source to collect oxygen from

It is recommended that you read the oxygen tutorial.

Once you have the materials, grab your rocket and launch into space! Once the Planet Selection GUI shows up, select the «Create Space Station» button at the top of the screen. There should be a new option in the Planet Selection GUI with «Space Station» in its name (you may also rename your space station on this screen after it has been created). Select it and hit the «Go to Dimension» button to go to your Space Station.

After you have made the Space Station you may want to add some Oxygen Sealers and Oxygen Distributors and some Air Locks.

Galacticraft 1

If you are still using the old Galacticraft, the materials required to create a space station depend on the prerequisite mod you installed, either IndustrialCraft 2, Thermal Expansion or Basic Components.

Moon Base

For a longer stay on the Moon, apart from the Fuel Loader and Empty Canister (needed to refuel your rocket to come home again), the items you should be taking to the Moon with you might include:

• power source — solar panels, wires and Energy Storage Module
• oxygen source — Oxygen Compressor, some dirt and seeds or saplings, or a couple of stacks of leaves
• a source of light
• food(!)
• Oxygen Bubble Distributor or Oxygen Sealer and some Oxygen Pipes

You might also want a couple of water buckets to make a water supply, although water can sometimes be found in Alien Villages.

If you are wondering what the Sealer’s, Collector’s and Bubble Distributor’s function and purposes are, oxygen can be provided to your Moon-base through the use of the Oxygen Collector. Breathable oxygen is created by planting two or more trees on the moon with a source of water nearby with the Oxygen Collector very close to the leaves of the trees. Then, connect the Oxygen Bubble Distributor to the Oxygen Collector with Oxygen Pipes, so that the oxygen can travel from the collector to the Bubble Distributor. The Bubble Distributor is meant as a quick way to get you started, so you can take your mask off. For a more permanent base you will probably want to build an Oxygen Sealer which can fill any enclosed space with oxygen. To «enclose» your future Moon-base, it’s just a case of making sure that the walls are solid, and you will need a door made of solid blocks. If you are good with redstone, you can perhaps make a piston door, otherwise Galacticraft has Air Locks. To make one of these you will need at least seven Air Lock Frames, and one Air Lock Controller — note that has Meteoric Iron in its recipe so it can’t be made until you get to the Moon.

Like all Galacticraft machines, the oxygen providing machines require a source of power to work. A good source of power on the Moon is the solar panel, so long as you have a couple of Energy Storage Modules to keep everything running during the long Lunar night. A Coal Generator might be good to have as a backup.

Can you live permanently on the Moon?

The short answer is yes, as long as you took some supplies with you for farming food — so some wheat seeds, and maybe some pumpkin seeds, cane, and chicken eggs (to make a chicken farm, and eventually pumpkin pie). You will also need saplings to grow trees (needed to make enough oxygen for the Oxygen Collector) and as a supply of wood — or you can maybe steal saplings from an Alien Village.

There are some mineral resources on the Moon: so you can gather plenty of copper ore and tin ore, and Meteoric Iron which is an important resource to build some of the more advanced mid-game items, and to get to Mars.

However, some materials are lacking on the Moon and can only be found on the Overworld. These include: iron ore, silicon, gold ore, lapis lazuli, redstone, diamonds, lava and obsidian. Maybe also ores from other mods (depending on your ). Also cobblestone, gravel, sand, flint and dirt! All are suddenly precious commodities on the Moon, as you will only have what you brought with you. To replenish supplies of these materials, and perhaps also for food or other items, you will probably need to return to the Overworld sometimes — at least until you reach Mars, after that you can maybe set up an automatic system of Cargo Rockets and loaders and unloaders to bring you the items you need.

There are mobs on the Moon (Evolved Creeper, Evolved Zombie, Evolved Spider, Evolved Skeleton) and also (in Galacticraft 4 Evolved Endermen, so you can find Ender Pearls on the Moon.

It is impossible to reach The End from the Moon, and it is hard to reach the Nether as a Nether portal cannot be ignited in a no-oxygen environment. (Future versions of Galacticraft may disable Nether portals totally in space dimensions.)

There are no animals on the moon, and you cannot carry living animals with you in a rocket (unless you have another mod giving you a way to transport animals). This means normally in Galacticraft the only animals you can have on the Moon with you are chickens, because you can at least carry eggs.

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.

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.

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

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.

Op-only commands

These commands are available only for ops (or from the server console). Note that being in NEI’s Cheat Mode is the same as being an op. In single player, you are automatically «Op» if you created the world and if you set «Enable cheats = On» in the world options when you created it (there are also ways for advanced users to change this later, by editing the levels.dat file).

dimensiontp

/dimensiontp — take the named player directly to the Planet Selection Screen without riding a rocket. If the argument is omitted, you will be teleported.

gcinv

/gcinv <save|restore|drop|clear> <playername> — applies the relevant command to the extended Galacticraft inventory slots (save the inventory for a later restore, clear it, or force drop all items). This is intended for use by automatic systems including other server mods and plugins. It can be used if you need to save+clear and later restore player inventories when they enter and leave a certain area (for example, a Spleef arena or other BattleArena). Detailed guide to the /gcinv command

gckeeploaded

/gckeeploaded — keeps a dimension (for example, a space station) from unregistering on a server when all players have left the dimension. This is needed for certain things to work properly on servers, for example Essentials teleport commands including and . There may be other solutions for the same problem. It should not be needed for planets, which are static dimensions (they stay registered all the time). It will not cause any lag. See also: Tutorials/Space Station for Server Admins

gckit

/gckit — gives a Space Emergency Kit item to the named player, or to yourself if no player was specified.

gcastrominer

/gcastrominer <show|reset|set<number>> <playername> — shows the number of Astro Miners a player currently has placed in the world. It can be reset to 0, or set to a given number. Players are not allowed to place more Astro Miners than a server set maximum limit (controlled by the config setting «`astroMinerMax«` in planets.conf, the default is 6). A situation where a server admin might use this is if a player lost an Astro Miner or it was destroyed by a chunk reset, map save error, etc etc.

gcssnewowner

/gcssnewowner <dim#> <playername> Each space station has 1 player who ‘owns’ it, and each player can only own 1 space station per planet orbited. Ownership gives guaranteed access to the space station for that player from his rockets, and allows the player to use the «`/ssinvite«` and «`/ssuninvite«` commands to invite his friends. The «`/ggssnewowner«` command allocates a new owner to an existing space station. Note: this command does not check whether the new player already owns a space station orbiting the same planet — but if the new player already owns a space station, he will lose ownership of it, so it will be ownerless until a new owner for it is set using this command.

Galacticraft 4: Compatibility notes

Galacticraft 4 is currently compatible with most other mods. For extra notes about Sponge compatibility on servers, see Sponge.

If you come across compatibility issues, please (1) check the latest Galacticraft version as we make compatibility improvements all the time; (2) if there’s still a problem in the latest, let us know on Github. Also try installing PlayerAPI mod, that can fix some compatibility issues. (The compatibility notes for Galacticraft 3, below, may also be relevant.)

Custom NPCs In Minecraft 1.10.2 and 1.11.2, please make sure to use the latest (25 May 2017 or later) version of this mod with Galacticraft, older versions had inventory tab overlapping issues.

More Player Models In Minecraft 1.10.2 and 1.11.2, please make sure to use the latest (25 May 2017 or later) version of this mod with Galacticraft, older versions had inventory tab overlapping issues.

TechGuns uses its own inventory tabs which overlap with ours — if this is affecting you, please ask the TechGuns developer to update and use our API for compatibility.

Fixed compatibility issues

Avaritia Infinity Armor and other mods with custom hi-poly armor — please update to Galacticraft 4 build 152 or later, to have the armor drawn correctly on planets

Finder Compass To prevent client disconnects, please update your Galacticraft 4 to build 4.0.1.143 or newer.

JourneyMap If you are using JourneyMap waypoint teleports to travel between different planets, please update your Galacticraft 4 to build 4.0.1.143 or newer.

Forge — mods missing screen If you get a crash with this type of error when you start the game: (Minecraft 1.10.2 might show instead of there) it might be Forge trying to give you that brown screen naming the required mods «missing», but crashing instead of showing the screen. To solve this issue, try updating Galacticraft and MicdoodleCore to the latest version.

Known compatibility issues

All Shaders mods — please switch off shaders when you leave the Overworld and travel to other planets — shaders mods cannot understand the dark or differently colored sky on the Moon and other planets.

Advanced Rocketry is a space-themed mod which has made some overlapping content with Galacticraft. If Advanced Rocketry and Galacticraft are installed together, Advanced Rocketry may take over some of the space dimensions, for example you may have some features of Advanced Rocketry’s oxygen system or gravity on the Moon instead of Galacticraft’s features on the Moon. For example, players have complained they can’t breath on the Moon when they are wearing Oxygen Mask, Oxygen Gear and full Oxygen Tanks — if you’re wearing those then it’s Advanced Rocketry which is stopping you breathing, not us. We are hoping the Advanced Rocketry guys will provide a config or other solution to avoid this conflict (like they did in the 1.7.10 version of their mod)

WAILA: some versions of WAILA have a bug where the color of grass, leaves, sand and some other blocks changes to grey when the player is mounted in a vehicle, including a Galacticraft rocket. If using WAWLA with WAILA, please make sure to use the latest Galacticraft version.

Cubic Chunks mod causes multiple weird issues with Galacticraft if you build outside the 0-255 height range — for example it can interfere with rocket launch and landing.

ViveCraft is compatible with Galacticraft, but it needs you to set a config setting: «Disable Vehicle Third-Person and Zoom»=true

Minor issues reported with PlayerRevive and Valkyrie Warfare mods.
