Bedrock Edition Far Lands



The Far Lands were the area that formed the "edge" of the "infinite" map in versions prior to Beta 1.8. The distance from the center of the Minecraft map to the beginning of the Far Lands, 12,550,820 meters, is about $1/3$ of the circumference of the Earth at its equator. When players made it to the Far Lands, they would experience an excessive drop in framerate and the terrain would be severely distorted. According to Notch, the distortion could be fixed, as it was in 1.8 (resulting in the disappearance of the Far Lands). A post on Notch's blog indicates that this fix was accidental, and was probably an unintended side effect of the large changes in terrain generation for 1.8. In 1.8, instead of the Far Lands starting to generate at 12,550,820 meters from the center of the map, the playable area abruptly ends at 30,000,000 meters, and fake chunks (they are not solid, they can be fallen through) start generating. A sure sign that one has reached the edge of the map is that lighting no longer works past the 30,000,000th mark. Versions between Alpha 1.2.0 (Halloween Update) and Beta 1.7.3 rendered fake chunks outside of a limit of 32,000,000 meters; attempting to walk onto them would cause the player to die in the Void. From the beginning of Infdev all the way to the Halloween Update, the world abruptly ended at 32,000,000 meters, and leaving the boundary caused you to be trapped rather than die.

Getting to the Far Lands
Getting to the Far Lands without the use of an external program was a very difficult (or at least time consuming) task, as walking to there from the center of the map would have taken approximately 820 hours (or 34 days). Instead, a level.dat editor could be used to teleport the player there.

The boundary between the normal map and the Far Lands (defined by when the map started generating the distorted terrain) occurred at X/Z of ±12,550,821.

The hard limit where chunks are overwritten is at X/Z of ±34,359,738,368, which is about 23% of the distance from the Earth to the Sun. At X/Z of ±2,147,483,648 (crashes at 2,147,483,439), item positions, mob pathfinding and other things using 32-bit integers will overflow and act strangely, usually resulting in Minecraft crashing.

At X/Z of ±1.798*10308, the position of the player, represented by a double-precision floating point number, would overflow to 'infinity', causing a complete breakdown of arithmetic. Even at far smaller coordinates, the limited precision would cause errors in calculations. For example, at 1016, xPosition + 1 is equal to xPosition.

Using Single Player Commands, it is very easy to get to the Far Lands using teleportation. After pressing the chat key (default "T") to open up the console-like input window, using the "teleport" command (or its abbreviation, "tp") followed by X, Y, and Z coordinates will allow the player to go wherever they want. In 1.3, you can turn on cheats to teleport. For example:


 * To get to where the Edge Far Lands' wall was, try "tp 12550820 129 0". Make sure either flying is turned on or damage is turned off, as otherwise you'll fall to your death.
 * To get to where the Corner Far Lands was (the walls' intersection), try "tp 12550820 129 12550820". Again, make sure you're protected from fall damage.

Unfortunately, there was severe lag, and slower computers used to crash upon this teleportation. Opening a GUI helped the Far Lands render much, much faster. You can do this by pausing (pressing Escape) or opening the Single Player Commands prompt again. When you venture out farther above and into the far lands, the probability increases that a "bad chunk" will appear. A bad chunk is a chunk filled with terribly corrupt data, and is the cause of sudden lag spikes that can easily make Minecraft crash.

Avoiding lag in the Far Lands
If you're using Single Player Commands, you can get rid of the lag by using several commands, which include (but are not limited to):


 * the killall command to remove all mobs, dropped items, and falling gravel/sand which will be about 4000 per 20 seconds. This should be used at least three times per minute to prevent severe lag from occurring.
 * the drops command to stop blocks from dropping items, so gravel and sand that fall will not cause any lag.
 * the light command to make all blocks as bright as possible so you can actually see the layers underneath the top layer. Also helps with hostile mob spawning, which in turn, increases frame rate.

This all will increase your frame rate to a value close to what would be experienced in the "normal" area of the map.

If you don't want to use mods, you can also avoid some of the lag by setting your game difficulty to peaceful via options menu.

Geography of the Far Lands
Both areas of the Far Lands feature extremely strange terrain, although they are significantly different. In both zones, any area beneath sea level, excluding regular caves, will be flooded with water. The Far Lands' structure is dependent on the seed used for generating the map, although the general patterns remain the same. Beyond X/Z of ±32,000,000, chunks are treated as permanently nonexistent, and will not generate, even though they may appear to. This value is hardcoded in the source code of Minecraft. This means it cannot be changed without editing the source files.

The Far Lands will generate biomes but most biomes will be indistinguishable except by the color of the grass. Desert biomes will be covered in sand and snow-covered biomes will be covered with snow, excluding the top of the map (because there's no space for the snow cover up there). Trees will generate somewhat normally, but can only be found in the upper areas of the map due to the need for grass. However, if you open Single Player Commands, the biome will always be Forest.

Ores can be found up to their respective maximum heights just like in the normal world. Unfortunately, due to the flooding, everything except for coal is difficult, if not impossible, to acquire. In the solid areas of the Far Lands, normal caves will generate but will be limited and small. Along with the caves, dungeons (extremely rare) and lakes can be found in solid areas. Water and lava springs can be found out in the open and in caves.

Much of the open space in both areas is shrouded in darkness and thus hostile mobs run rampant, making the Far Lands as a whole incredibly dangerous. This is especially problematic in the Corner Far Lands due to its layered structure. The flooded zones are filled with squid.

In the Sky Dimension, the Far Lands are not half flooded with water and bedrock does not form at lower levels.

Edge Far Lands (The Loop)
The boundary of the Far Lands Edge (that is, where it meets the regular map) looks like a solid wall, all the way to the top of the map (Y-coordinate 127) that is filled with gaping holes perpendicular to the edge. These holes are extremely long, perhaps infinite, and on the whole seem to change very little no matter how deep the player ventures. They can be blocked, either partially or completely, but such blockages are rare and temporary. This "wall of Swiss cheese" pattern continues beneath ground level, all the way to the bottom of the map, and seems to be partially caused by a large one-dimensional distortion in the map generator's output.

Corner Far Lands (The Stack)
At a corner, when two perpendicular Edge Far Lands sections meet, the Corner Far Lands begin to generate. Unlike the infinite-length holes in the Edge Far Lands, the Corner Far Lands contains more normal terrain. This terrain is "stacked" on top of itself to create a bizarre sandwich with layers of ground and air, which gives it its nickname. Each layer looks like a gigantic floating continent, hovering over the next layer, which is shadowed.

The majority of the generated world is Corner Far Lands, as the "normal" map (before 12,550,821) only makes the center of the world, and the Edge Far Lands only makes its continued sides.

The number of layers isn't always the same, and varies between five to seven. Layers can be grouped into three categories:
 * The top layer. This layer exists at the absolute top of the map. Occasionally there can be a lower area that isn't shadowed (this is technically a dry layer). The lower area is where a majority of the trees and passive mobs can be found, as the top layer receives almost all of the sunlight. Due to the lack of space the area at the absolute top can't have trees or mobs.
 * The dry layers. These generate slightly flatter than normal terrain and have grass, despite the darkness. At sea level massive floating beaches can be found, which will collapse if modified. Hostile mobs are very common here due to being in the shadow of the top layer. Rarely, there are holes in the top layer that allow sunlight to reach these layers. Caves that have one of these layers as their "surface" can occasionally be carved out of dirt instead of stone. These layers have cave-like ceilings made out of stone, gravel and dirt.
 * The flooded layers. Like the dry layers, these generate somewhat flat terrain, but it is comprised primarily of stone. Sand and sandstone will show up down here, even up to 30 meters below sea level. Except for coal, all the ores can only be found in these layers.

Sometimes there are extremely tall pillars of gravel that stretch from the ground to the ceiling of a layer. Likewise, some of the beaches that collapse will create pillars of sand all the way down to the ground, despite there not being that much sand to begin with. The Corner Far Lands is also prone to having near-perfect diagonal lines being carved into the ceilings or floors of layers. If traced, these lines all intersect at the corner (X/Z ±12,550,821). This seems similar to how the Edge Far Lands have a consistent pattern along lines perpendicular to their edge, but is much less pronounced.

In the Nether


The Nether Edge Far Lands look identical to the regular Edge Far Lands, except with Nether blocks. They're constructed out of Netherrack with some Soul Sand mixed in. Glowstone will be found in coral-like structures like the rest of the Nether. Both the floor and ceiling bedrock layers will be present, as well as the lava ocean (at Y-coordinate 31). The Nether Corner Far Lands also look identical in nature to their real-world counterparts (although not necessarily exactly the same). They have a similar stack of layers and contain layers flooded with lava (at levels 31 and below) instead of water.

In the Nether, the terrible lag associated with the regular Far Lands will not occur. This is because there is no sand and very little gravel in the Nether.

If a nether portal is created in the Far Lands of the Nether, entering will cause the purple teleportation animation to continue to swirl around your screen.

In some cases, mostly in 1.0.0, a player will not be able to place or destroy any bricks and most of the generation becomes clear. if this is the case the giant wall will seem to despawn. In these cases there are usally also a corresponding effect of there being a lot more caves generated

Effects of the Far Lands


There are many effects that will be noticed after traveling millions of blocks away from the center of the map. The very first effect that will be noticed is the jumpy or stuttering movement of the map, which isn't directly related to the Far Lands themselves but instead to floating-point precision errors. This jumpy movement is notable even at X/Z of ±500,000. Players will experience extreme framerate drops and very high CPU usage, which will continue until Minecraft freezes completely. The framerate drops do not occur in multiplayer servers, though it will, depending on the server computer's RAM, make the server itself lag. In both Single-Player and multiplayer, the intense lag that is characteristic of the Far Lands is caused by massive numbers of falling sand or gravel entities. This in turn is caused (like most of the rest of the Far Lands' strange effects) by more floating-point precision errors.

As the player journeys even deeper into the Far Lands, the effects worsen to the point where the game is unplayable. At X/Z ±32,000,000, block physics stop functioning correctly. Lighting doesn't work and the blocks, although they appear to be there, aren't solid. If the player tries to walk on these blocks, he or she will fall into the Void. Because of this, it's impossible to get even close to X/Z ±34,359,738,368 or ±2,147,483,648 without the assistance of editors or mods. At excessive X/Z positions, World Renderer no longer works, or takes incredibly long times and uses most, if not all CPU usage. It then becomes almost impossible to close Minecraft without a task manager.

Weather is not affected by the Far Lands directly but is by their terrain. Lightning bolts that hit surfaces at the top of the map (Y-coordinate 127) will be invisible and will not cause fire. The particles created when rain hits these surfaces will be black instead of blue. Snow will not accumulate on these surfaces either (because there's no space). As of Beta 1.6, these effects are unique to the Far Lands as it's impossible to artificially place solid blocks at layer 127.

In Beta 1.8 and above


As of Beta 1.8, some of the strange terrain may be gone, but some of the effects aren't.
 * After X/Z ±30,000,000, the world will start generating fake chunks, where lighting doesn't work and blocks stop clipping. Fake chunks are composed of grass, dirt, mycelium, sand, bedrock, stone, (ice on rare occasions, but only spawning 1 block at a time) (or Netherrack if you're in the Nether far lands), water, and lava only. No foliage such as trees or grass will generate, nor will mobs.  If trees happen to generate next to the edge between the normal overworld and the far lands, then the trees will appear to "cut off" on the far lands side. There is a dark line of dirt seperating the 2 types of chunks. It is possible to walk on them if on the edge.
 * Fake chunks are non-solid; entering them will cause you to fall into the Void.
 * Past the point of 12550868 X/Z, Villager NPC arms will fail to render. However the rest of the body loads perfectly.
 * Flying about 32 blocks past the edge of a fake chunk will trap you in the air, immobilizing you. This happens with all entities. This seems no longer be the case as of 1.3.1 and further versions.
 * Also, the clouds will act strangely, moving at abnormally high speeds. Reloading the save should fix the clouds, but the position glitch will still be present, It will be impossible to escape.
 * Chunks stop rendering after X/Z of about ± 30,000,064
 * This seems to no longer be the case as of 12w27a.
 * Water and lava's visual overlays do not render at all considering the nature of blocks in the far lands.
 * At excessive X/Z positions, particles (rain, water, snow, etc.) fail to appear staggered, instead forming rows of flat "panes".
 * The Far Lands do not lag in Beta 1.8.
 * Ladders do not have hitboxes.
 * In 1.3.1 (positions unconfirmed for lower versions)
 * Torch Flame Light stops centering on its torch after block X/Z of ± 8,388,607
 * In the ± X Directions, it will render on the center of the X edge
 * On the -X side for odd blocks
 * On the +X side for even blocks
 * In the ± Z Directions, it will render on the center of the Z edge
 * On the -Z side for odd blocks
 * On the +Z side for even blocks
 * In the corner past X/Z of ± 8,388,607 it will render in the corner of the block
 * On the +X/Z corner for odd X/Z blocks
 * On the -X +Z corner for even X odd Z blocks
 * On the -X -Z corner for even X even Z blocks
 * On the +X -Z corner for odd X even Z blocks
 * Piston Shafts Stop Rendering correctly after X/Z of ± 2,097,151
 * They render 2 dimensionally in non-corners between X/Z of ± 2097151 and X/Z of ± 8,388,607
 * They do not render at all in corners between X/Z of ± 2,097,151 and X/Z of ± 8,388,607
 * They render as 3 dimensional rectangles in non-corners after X/Z of ± 8,388,607
 * When facing up or down, they render as 3 dimensional squares (full block size) in corners after X/Z of ± 8,388,607
 * Redstone stops rendering and connecting correctly after block X/Z of ± 4,194,303
 * After X/Z of ± 1,048,576 redstone is still small but it got a little bigger and After X/Z of ± 4,194,303 it does not appear as a single pile at all except for the corners past X/Z of ± 8,388,607 where it appears as a very large pile until you get to X/Z of ± 16,777,216 the redstone appears two times the size of the large pile and could only render in certain places.
 * Rain stops falling in random patters after X/Z of ± 8,388,607
 * In non-corners it falls in rows on the side of the blocks
 * In corners it falls on just the corner of every block

Additional effects occur in 1.0.0:
 * The fire of torches will appear in/on a block next to the torch, instead of on the torch itself.
 * At and past X/Z of ± 8,388,607 lit TNT will Jump to the corner of the cell it was lit in. this means Cannons are impossible.
 * Piston heads will disappear when the block is activated, and will have the same effect as sand does when falling (then disappears).
 * Paintings can be placed over other paintings near the far lands.
 * The floating book in the enchantment table seems to behave abnormally when a player is moving near it.
 * Redstone occasionally appears extremely distorted, with stretched graphics. It can also appear misplaced, or completely invisible, but the highlight box still appears indicating where redstone is placed.
 * Cauldrons, when looked from the inside, one of the sides is translucent, and the graphics for that side appear one block away from the cauldron on the opposite side of where the texture is missing from.
 * Highlight box for cake fails to appear correctly.
 * Lily pads fail to appear.
 * Flames from a monster spawner only appear on one side of the block.
 * Many lighting glitches and strange air pockets form on multiplayer, although untested in singleplayer.
 * The graphic for end portal block fails to appear correctly, and redstone ore particles are only in the corners.

As of 12w18a, the phantom chunks will start generating chunks as of the regular world and you could go over the 32 block limit.

As of 12w25a, the game lets you travel past 30,000,032 meters until it says "Illegal Position" at 32,000,000 meters.

Map editors
When viewing the Far Lands (Beta 1.7.3 and below) in a 3D Minecraft map editor, you will encounter errors. In MCEdit, the selection cubes start to distort and the map distorts when viewing.

In previous versions of Minecraft
Very little is known about the Far Lands of older versions of Minecraft for many reasons; they had no official name, and few knew of their existence. Fewer still tried to make them known to the world, and so they remained unknown. When Notch mentioned them on his blog and gave them an official nickname, interest took hold.

In Infdev, although the Far Lands existed, many of the side effects didn't. However, fire particles and doors would act strange. There was no lag or stuttering movement, and beyond X/Z ±32,000,000, the blocks would simply not render. Walking off the edge would cause the player to become stuck in a glitched position, unable to escape.

It has been confirmed that in Alpha v1.1.2, the blocks would not render beyond X/Z ±32,000,000, like older Infdev versions. The fake chunks started appearing in Alpha 1.2.0, the Halloween Update.

Trivia

 * The Far Lands spawn hostile mobs at a rate far higher than any natural chunk, due to the sheer amount of space in absolute darkness. In the Corner Far Lands, the spawn rate likely approaches the maximum possible because the stacked terrain works like a mob tower.
 * The flat plane at the very top of the Corner Far Lands tends to light incorrectly in day-night transitions. This is because the sunlight calculation doesn't work when the entire chunk is blocked at Y-coordinate 128.
 * Even traveling through the Nether, it would take 102 hours (or almost 5 days) of walking in a straight line to get to the Far Lands.
 * Entering a Portal which would take you to either world's Far Lands will cause Minecraft to crash. e.g. Building a portal at 2,000,000 in the Nether would take you to 16,000,000 in the Overworld, but this would cause a crash. The same cannot be done vice versa, because building a Portal which will take you to 12,550,820 in the Nether can only be done at X/Z of over 100,000,000 in the Overworld, that is, a distance more than 3 times greater than the point beyond which blocks can not be placed anymore.
 * When at the Far Lands, fences either have a thin wall collision box on one side, or no collision with mobs or the player.
 * If the player places a painting, it will be off by a few blocks from where it should be.
 * The Edge Far Lands' average block composition: 36% Stone, 25% Air, 23% Water, 10% Dirt/Grass, 2% Bedrock, and 4% others. (Based on a 14x14 chunk selection)
 * The Corner Far Lands' average block composition: 40% Stone, 16% Air, 28% Water, 10% Dirt/Grass, 2% Bedrock, and 4% others. (Based on a 14x14 chunk selection)
 * Even though Beta 1.6 made it impossible to place solid blocks at layer 128, the Far Lands' flat "ceiling" still gets generated there.
 * Because of the debates over renaming Endermen to "Far Landers," Notch jokingly suggested to rename the Far Lands to The End instead. This then became the name for the dimension where the Ender Dragon resides.
 * Notch still hasn't confirmed if he will re-add the Far Lands to the game, since it's almost impossible to get there without mods.
 * The Far Lands could cause major decrease in FPS, freezing, and crashing.
 * Even though the Far Lands themselves were removed, some of the bugs still happen, such as particle displacing. This can be seen if a torch is placed; the flame/smoke will be off-centered. Also, redstone looks weird; it expands outside the block boundaries.
 * When one travels past X/Z of ±30,000,000, fake chunks will generate and will have no clipping and the player will fall into the void and die. (tested in 1.4.5)
 * The farthest one can go without a severely high chance of crashing is X/Z coordinate 2,147,483,647. 32-bit machines will not last beyond this limit, as this is the highest 32-bit integer, therefore 64-bit Java may be able to handle going farther.
 * It is very dangerous to reach X/Z 4,000,000,000 or higher, as the chances of crashing (assuming you have 64-bit Java) are extremely high, and get higher the farther you go.
 * If one makes it to X/Z 34,359,738,368, chunks will start getting overwritten.
 * The highest value for 64-bit machines is X/Z 18,446,744,073,709,551,615.
