The '''[[Minecraft:Far Lands (Java Edition)|Far Lands]]''' were a terrain bug that occurred in versions of {{MC}} up to Beta 1.7.3. They were caused by errors in the math that governs terrain generation, resulting in abnormal structures resembling excessively stretched-out terrain. They were fixed in [[Minecraft:Java Edition Beta 1.8 Pre-release|Beta 1.8 Pre-release]], and moved far beyond the boundary to 53,905,378,846,979,748 blocks from spawn. Reaching this distance is impossible without extensive modding. In addition, most of the [[Minecraft:Java Edition distance effects|distance effects]] were fixed. The Y Far Lands (aka the Sky and Ground Far Lands) were overlooked, but were fixed in 1.13 with the world generation rewrite. Prior to the removal of the first iteration of [[Minecraft:Custom]] worlds, it was possible to force the Far Lands to generate by setting the Coordinate Scale to extreme high values.

Beginning in [[Minecraft:Java Edition 1.14.4|1.14.4]], additional changes to the way the fix worked pushed the Far Lands to [[Minecraft:Far Lands (Java Edition)/Release 1.14.4 to 26.2.1|even further distances]].

== Explanation ==

The Far Lands were a terrain generation bug that occurred at ±12,550,824 along the X and Z-axes prior to Beta 1.8, as well as the Y-axis (technically) before Java 1.13. The Far Lands generated because of an integer overflow error within Minecraft. The [[Minecraft:noise generator]] that draws Minecraft's height map increases by 684.412 for every four blocks, causing an integer overflow at approximately ±12,550,824 (sometimes ±12,550,821.) Multiplying the aforementioned numbers and dividing the noise scale by 4 results in the 32-bit signed integer max value, which when overflowed, results in an extreme noise seed.

In [[Minecraft:Beta 1.8]], as part of changes to terrain generation, the following code, referred to as the '''"modulo" patch''', was added within the <code>NoiseGeneratorOctave.java</code> file:
<syntaxhighlight lang="java">
for (int var16 = 0; var16 < this.octaves; ++var16)
{
double var17 = (double)p_76304_2_ * var27 * p_76304_8_;
double var19 = (double)p_76304_3_ * var27 * p_76304_10_;
double var21 = (double)p_76304_4_ * var27 * p_76304_12_;
long var23 = MathHelper.floor_double_long(var17);
long var25 = MathHelper.floor_double_long(var17);
var17 -= (double)var23;
var21 -= (double)var25;
var23 %= 16777216L;
var25 %= 16777216L;
var17 += (double)var23;
var21 += (double)var25;
this.generatorCollection[var16].populationNoiseArray(p_76304_, var17, var19, var21, p_76304_5_, p_76304_6_, p_76304_7_, p_76304_8_ * var27, p_76304_10_ * var27, p_76304_12_ * var27;
var27 /= 2.0D;
}
return p_76304_1_;
</syntaxhighlight>

This was present in every following version, including Beta 1.8, up to [[Minecraft:Java Edition 1.14.3|1.14.3]]. It essentially prevents the noise generator from suffering integers overflowing by clamping the input before being passed. It also allows for the terrain to "wrap around" and continue generating normally even at high distances. By removing everything from <code>long var23</code> to the last <code>(double)var25;</code>, the patch is undone, and the Far Lands can be moved back within vanilla boundaries at their original locations.

== Location ==
[[File:Far Lands in 1.8.1.png|thumb|Far Lands generating in 1.8.1 with the patch removed]]
If the modulo patch is undone, on the X and Z axis, the Far Lands and Farther Lands initiate as they did in Beta 1.7 and below (±12,550,824), with an identical chance of offset at positive positions. However, due to the new height limits and new world generation, they are actually 256 blocks high. On the Y-axis, the Far Lands initiate at around twice the former number, which is therefore ±25,101,648. The Farther Lands also generate at ±2,008,131,840 on the Y-axis, however, they cannot be generated without lowering the selector noise period.

The new position due to the modulo patch is at X/Z: 53,905,378,846,979,748. As such, this makes them impossible to view in vanilla gameplay, due to imposed limitations and how ''Minecraft'' is designed.

== Structure ==
Whether enabled by simply removing the modulo patch or going to the new location where they generate,The edge Far Lands and corner Far Lands, as well as their Farther variations, generate relatively identically to their pre-Beta 1.8 counterparts, but utilizing the entire height limit. In versions prior to [[Minecraft:Java Edition 1.7.2|1.7.2]], they remained capped at y=128 despite the change in world height; afterwards, they will generate up to y=256. By modding the world height to continue indefinitely, they can continue up until they reach the sky Far Lands at y=+25,101,648 (and equivalently the ground Far Lands at y=-25,101,648).

=== Far Lands ===
==== Sky Far Lands ====
{{outdated|section=1|The ''[[Minecraft:Old Customized|Customized]]'' world type was removed in [[Minecraft:Java Edition 1.13|1.13]], so the Sky Far Lands can no longer be generated without mods.}}
[[File:Far lands on Y.png|thumb|right|The Far Lands generating on an unmodded modern custom world, before 1.13. A high coordinate scale was also used to generate this, resulting in repetitive terrain.]]

The Far Lands generate at positive values of the Y-axis past y=25,101,648. [[Minecraft:Monolith]]s generate up to this point if the player can get them to generate.

Setting the Height Scale extremely high can generate the Far Lands in the sky up to the height limit.

This is possible in Vanilla.

==== Vertex Far Lands ====
When the Sky or Ground Far Lands meet with the vanilla Corner Far Lands, many interesting terrain features can be sighted. The content of these intersections appears to vary throughout worlds, with some being completely blank, some completely solid, and some generating like regular Far Lands material. In some cases, diagonal patterns with large absent chunks generate.<ref>{{ytl|-w6okOz-iNs|Minecraft Stops Here. Please Turn Around!|AntVenom|January 20, 2018}}</ref>

=== Depth noise Far Lands ===
Like low/high and selector noise which respectively control the Far and Farther Lands, depth noise can be made to overflow at a given position. By default, it overflows at 42,949,672.96 blocks. Due to the Far Lands initiating before it, the overflow in depth noise is effectively impossible to see. However, if depth noise is made to overflow before tradition far lands, achievable by pushing the far lands farther out than this distance or moving the depth noise far lands closer, the effects can be seen immediately as it overflows, the terrain jumps up a few blocks. Terrain after this point is slightly more boring than before due to depth noise controlling subtle variation, which no longer exists after the overflow due to it almost always being at the max possible value. Every so often, very long "rifts" characteristic of depth noise far lands can be seen, which extend for extremely long. These rifts end once they hit the point twice the distance of the first overflow, and rifts as a whole past this point do not seem to be able to come into existence. Rifts have also only been noted on the positive X axis and are yet to be found on the Z axis.

===Dimensions===
==== The End ====
The End was implemented after the Far Lands were removed, meaning that the End Far Lands never generated naturally.

==Summary==
The Far Lands were never actually removed from the game in Beta 1.8. Rather, what ''was'' fixed was integers and noise values overflowing at the 32-bit limit, and thus putting the new start way beyond the boundaries of a normal ''Minecraft'' world. As such, by patching the game to reverse this change, or by using a BigInteger mod, the Far Lands can be brought back. However, their location, makeup and progression depends entirely on the version and/or method used. If the game is modded to simply undo the modulo patch that fixed the original Far Lands, then they will generate at their original starting point of X/Z: ±12,550,821. The limit to how much of the Far Lands will generate is dependent on what mods and/or version is being used. If only the patch is reversed, then it will vary due to various vanilla features throughout different versions that affected the edge of the world.

The only way to see the new locations of the Far Lands is by using a 64-bit mod or BigInteger mod that does not patch the fix. If a 64-bit mod is used, the [[Minecraft:Java Edition distance effects|distance effects]] will continue to progress as one goes further; while the BigInteger mods end up patching these.

* The Far Lands begin generating due to the "modulo" patch breaking down, resulting in noise value overflowing at this point. Because of the three-block offset that sometimes happened in the vanilla Far Lands, this offset is instead measured with a 12,452,760 block difference (but not a scaling of the original offset).<ref>[https://youtu.be/F8cMZA8J2Hk?t=473 breaking Minecraft's FINAL Distance Limit…], YouTube, April 1, 2021</ref>

* The Far Lands begin degrading into thinner slices due to the decay process, in three stages at the aforementioned distances.

* The Far Lands end completely at this point, though the end point is different on each axis, as they continue until at least 20 quindecillion on the Z axis. This marks the end of ''Minecraft'' terrain generation, unless extensive modding on top of this patches the noise overflow and Far Lands.
* As stated before, the end point is inconsistent due to how the decay works and does not result in a specific point each time, and will vary by seed.

== Effects ==
While completely unrelated to terrain, these effects occur coincidentally with Far Lands due to their shared extreme distances and are worth noting as a result.

=== Floating-point precision errors with entities and particles ===
{{main|Java Edition distance effects}}

Even in modern versions of Minecraft, the floating-point precision errors still exist, but only with translucent block rendering, natural snow generation and snowfall at extreme heights.

=== Darkness ===
{{main|Java Edition hard limits}}
In vanilla Minecraft 1.14, the lighting system breaks beyond 225 (X/Z ±33,554,432)<ref>{{bug|MC-194878}}</ref> (though this distance is available only via editing source codes), however, it isn't like what would happen beyond X/Z=32,000,000 in older versions. Instead, everything abruptly becomes absolutely dark and ignores light sources. By pressing F3, it shows that the sky light level is 0, thus [[Minecraft:Undead|undead mobs]] do not burn when exposed to the sky. The chunks, however, are still solid and block physics still function. Night Vision can help to counteract the visual darkness; it is currently unknown whether the [[Minecraft:Conduit Power]] effect works or not.
