The Nether



The Nether (Also referred to as "The Nexus" in Notch's Blog and was previously known as Hell and The Slip) is part of the Minecraft Halloween Update. It exists in a completely different world from the normal world above. The terrain is dimly lit, full of lava streams flowing from the ceiling, sudden cliffs, and lava lakes, making it extremely dangerous to explore. The ceiling and the base of the Nether are made of bedrock. Mushrooms are also commonly found. If the player dies in The Nether, they will be transported back to the spawn point on the surface world.

Portals and Fast Travel
The portals are made by creating a 4x5 (2x3 on inside) door frame out of obsidian and then lighting the inside of the frame on fire with Flint and Steel. The corners of the frame may be left out, using only 10 obsidian. When you stand inside the portal for the first time, it will create a portal in its equivalent area of the Nether. A loading screen will appear during the change of worlds.

A portal can be shut down if part of the obsidian frame is removed.

When re-entering the normal world, any distance covered in The Nether is multiplied by 8, effectively making The Nether a fast travel zone that allows for greater distances to be covered in a short amount of time in the normal world.

A form of nether portal travel can be extremely useful especially for the use as before said fast travel. However their are certain rules that do apply with this travel and most of them have to do with the location of the new portal created in the normal world. The first portal that gets a player to the nether is the only portal in the normal world that creates a portal in the nether after that all other portals built in the real world will connect with this main portal and this can be used for extremely fast travel back to your original base. Now portals in the nether are different as long as they meet the rules they will connect to the real world. As said before everything in the nether is 1/8th of the normal world using this ratio you can travel very far.

The portal must be built outside of sound range of any other portals. If it is within range the portal will then simply connect to the original one in that area. This is not true in older versions of Minecraft but in the newest currently Beta 1.2_02 this is true. Once a portal is outside of this noise range it will then after being built calculate the related location in the real world. The first thing the portal will do is search for an area in roughly (not 100% proven) a 8x8 or 10x10 block area. The portal may be height relative tests completed on this idea so far have worked like this. After creating a portal in the nether and going to the normal world a hole was dug and then at the bottom of that hole an area was cleared big enough to house a portal. The old portal was destroyed and then the test was done to see if height was relative since the hole had been dug below the point where the portal was created. The first and third tests turned up some large questions. The first portal came out on the surface then the hole was dug. The first true test spawned the gate in a cavern nearbye instead of in the hole. The second test worked wonderfully and was created in the hole. The third test then did once again what the second one did popping up in a nearbye cavern. These three tests show that their may be some randomization to a portal from the nether after all sadly it still does not show whether the portals are height relative as well as horizontally or x and z relative.

Because the nether is 1/8th the size of the normal world this means that an attempt to reach the end of the world, that being if there is one, the nether would be the fastest way to do so. Also by using minecart systems one could create a complex and extremely fast and comfortable way of travel if they are willing to of course risk the dangers of the nether. By using glass or a strong material a player could effectively make the nether safe to travel in as well though their work would be still cut out for them.

Walking through a portal will not teleport the player - in order to use them, the player has to stand still inside the purple haze. Currently, they will not transport mobs or minecarts. Attempting to go through a portal while in a minecart will result in the player needing to restart the game to continue.

Mobs
Mobs that spawn in the main world do not appear here. Instead, there are special mobs that appear only in the Nether (although Ghasts have an extremely small chance of spawning through a portal on the surface world.)


 * Ghasts - Flying jellyfish-like monsters that shoot fireballs. They can be damaged by any conventional weapons, but they do not get hurt when on fire, only when touching it. A Ghast can fly into lava falls or lava lakes, but even if they burn they don't get damaged (As of the November 10th Update). The fireballs they shoot can be deflected back at them using a fist or any tool by hitting it just before impact (shooting an arrow or using the Fishing Rod on the fireballs works too). They drop sulphur, But is very hard to obtain, since they're always flying around over lava lakes. Creepers provide a better source of sulphur.


 * Zombie Pigmen - Peaceful, humanoid creatures that turn hostile when attacked. They drop a cooked porkchop when killed. They carry gold swords, and do 2.5 damage. They often appear in packs of 4, and tend to stay together. If one Zombie Pigmen turns hostile, then so will every one in the range of 32 blocks. The only safe way is to fight a zombie pigman in a pack of: 1.

Blocks
Blocks can be brought to and from the main world. So far, there are three block types only found in the Nether:


 * Netherrack - This block burns indefinitely, and is the main block type forming the Nether. Setting these on fire while traveling in the Nether is a great way to save on torches.


 * Glowstone - A golden block that glows indefinitely, commonly found as stalactites on the ceiling of the Nether. These can be used as a light source underwater on the surface world, and the powder produced when it is mined is suspected to be an ingredient in making lanterns.


 * Soul Sand - A brown block resembling a creeper face. When walked on, it slows the movement speed of the player and mobs that walk across it, and makes them sink down a tiny bit.

There are three blocks that spawn in both worlds: Lava, Gravel and Bedrock. Also found in both worlds are both brown and red mushrooms.

Water
Water cannot be placed from buckets normally in the Nether. Instead, it generates a steam effect and the fizz.ogg sound effect (the same used when lava destroys an object) is played. If an inventory hack is used to give the player a water block, they can place the block. The water block will behave and flow normally, and it will react with lava as usual, creating obsidian. Another way to place water in The Nether is to place a block of ice and break it; water will flow normally from it. Squid can also spawn in water placed in this way.

Because water is normally unplaceable in The Nether, if a player falls into a lava pit or otherwise catches fire, they are unable to put themselves out. [It has been noted that walking through the Portal whilst on fire extinguishes the fire once on the other side].

Planting & Growing
As water cannot be placed in the Nether, Reeds will not be able to survive. Wheat, however, can be grown on well-lit dirt blocks, albeit slowly. Using a sapling and a dirt block (don't forget a source of light), Trees will be able to grow. Its leaves will take a dead-looking brownish colour. Cactus blocks will also be able to grow normally, provided they are planted on Sand. In addition, flowers can survive in the Nether, but only with a light source nearby.

Naming
In the original announcement, Notch mentioned "a brand new Hell world". However, he's made it clear that he doesn't want to use religious names (as mentioned in this article), and prefers for Minecraft to be unique. When the preview was sent out on 29 October 2010 to a couple of gaming websites, the new dimension was called the Slip. This was changed to The Nether on the day of the update release. It has since been referred to as 'The Nexus' on his personal blog, although there has been no indication as yet that there will be another name change.

Ambience
The most common ambience in the nether is the ghast's sounds. It plays ghast.ogg which is a sound file which sounds like evil children screaming and crying for help. Zombie Pigmen usually oink and slurp.

Trivia

 * When you warp from worlds, the direction you are facing is maintained (e.g., if you face east in the overworld and warp to the Nether, you will still be facing east).
 * While inside the Nether, Clocks and Compasses will be unable to tell the time or direction and will flail back and forth.
 * While inside the Nether, furnaces will stop smelting and plants will stop growing/decaying in the overworld. However, the day/night cycle continues while in the Nether.
 * It is possible, but very rare, for a Nether biome to be created on The Overworld. This is due to a bug.
 * The idea for the Nether came from a transportation method used in the novel series The Wheel of Time by Robert Jordan. Within this transportation system, the Ways, you could travel a massive amount of distance in a few days instead of weeks. Like the Nether, the Ways has many dangers.
