基岩版中的某些事物会在玩家长途旅行时逐渐崩坏。

第一极限(X/Z ±0–65,536)

基岩版在许多计算上都会使用32位浮点数,例如玩家的位置。当玩家移动时,玩家会在每一个刻上不断改变位置,它会受到浮点精度误差的影响。在低速且距离遥远的位置上误差会被忽略不计,这导致玩家无法移动。浮点精度误差会在2的每个幂次翻倍。

虽然实体中心的位置存储在NBT中,但碰撞箱角的位置存储在内存中。当玩家走过2的每个次幂时这些角分别可能会以不同的速度移动,导致碰撞箱的大小被改变。在某些情况下(比如重载世界、使用/tp命令或者其他方式[需要更多信息])会使碰撞箱大小重置为0.6。玩家的碰撞箱大小有可能会变成0,导致玩家穿过方块边缘掉入虚空(MCPE-39299)。

有一些方法能够降低玩家的移动速度,比如说潜行状态效果、使用物品(比如拉蓄力)或者进入某些方块中(比如蜘蛛网)。另外,沿对角线移动会降低玩家在任何给定轴上的速度。向对角线前面的方块移动会导致玩家向侧面移动,移动速度与玩家坐标允许的一样慢。

位置 现象
X/Z ±256(28 虽然这个位置上不太可能,但这是可能掉出世界的最近位置。由于故障是由受不同级别的浮点精度误差影响的碰撞箱角引起的,理论上可能在X/Z±1时就可以发生这类事件。但这至少需要耗去近6游戏日的时间(如果在此之间退出过游戏还必须重新计数)。
X/Z ±1,024(210 在生存中使用最慢的移动方式在非固体方块上移动在这个位置后变得不可能。(通过饮用神龟药水II得到缓慢VI效果并潜行和站在甜浆果丛和冰上的蜘蛛网的间隙中使用物品实现)。
X/Z ±16,384(214 非常小的抖动感可以在这个位置上感受到。
X/Z ±32,768(215 在上面有蜘蛛网的灵魂沙上潜行并拉弓将无法移动。[1]

抖动(X/Z ±131,072–524,288)

Eventually, some common forms of movement begin to glitch. In addition, blocks with very detailed models begin to render incorrectly.

Coordinates Effects
X/Z ±131,072 (217)
  • Climbing up ladders and vines while sneaking is slightly slower than normal.
  • Sneaking diagonally starts to become bumpy.
  • Lecterns, tripwire hooks, and the handle part of levers will start to become distorted.
X/Z ±262,144 (218)
  • Climbing up ladders and vines while sneaking is even slower and less smooth.
  • Sea pickles will render with slightly thinner stems than normal.
  • Tripwire string becomes invisible.
  • Sweet berry bushes and cobwebs appear slightly larger.
  • Sunflowers become glitched.
X/Z ±524,288 (219)
  • Paintings will be placed halfway inside the block, allowing multiple paintings to be placed on the same block.
  • The inner part of item frames render flush along the block.
  • Moving horizontally while on cobwebs becomes impossible.
  • Jitter is very noticeable beyond this point

3D方块模型渲染错误(X/Z ±1,048,576–8,388,608)

Blocks are rendered based on their corners, whose coordinates are 32-bit floating point integers. Generally, these are multiples of 116. Thus, most blocks render normally as long the floating points are accurate to the nearest sixteenth. This breaks at X/Z ±1,048,576 (220), and blocks continue to render incorrectly as the coordinates go even farther out.

In addition, many "normal" forms of movement become impossible.

Coordinates Effects
X/Z ±1,048,576 (220)
  • Walls render wider than normal.
  • Fences (excluding the posts) and closed fence gates render completely flat.
  • Doors and open trapdoors render thinner than normal.
  • Iron bars and glass panes render twice as wide than normal.
  • Climbing up ladders and vines is impossible without holding the jump button, and climbing up them while sneaking is extremely slow.
  • It becomes impossible to sneak outside the X/Z axis.
  • The cube inside slime blocks will be slightly wider.
  • The cube inside honey blocks is stretched to a full block, which results in a flickering effect.
  • Cakes appear stretched to full block.
  • Fire will render a bit differently.
  • Sea pickles render in slightly different places without the stem.
  • Lanterns render wider than usual and without the top part.
  • The logs in campfires render farther apart, overlapping with each other.
  • In brewing stands, the base renders incorrectly and the central pole is invisible.
  • The base of anvils will render incorrectly.
  • The supports of grindstones will render incorrectly.
  • The sides of item frames render wider than the top and bottom.
  • Flower pots will be slightly wider.
  • The inside of beacons will render incorrectly.
  • The supports of bells will render incorrectly.
  • Horizontal end rods render flat, while vertical End rods only render with their bases.
  • Redstone renders slightly differently.
  • Torches become invisible.
  • Buttons placed anywhere other than the sides of blocks will be distorted and such buttons are pushed all the way into the block.
  • Pressure plates cover an entire block.
  • Redstone repeaters and redstone comparators render without torches.
  • Cocoa beans in the second stage render as wide as mature cocoa beans.
  • Cacti render as full blocks, with gaps at the edges.
  • Bamboo renders wider than normal, flat, or invisible.
  • The dragon egg appears to be more blocky.
  • Turtle eggs are distorted.
  • The small bumps on chorus plant stems disappear.
X/Z ±2,097,152 (221)
  • Moving while sneaking becomes impossible.
  • Walking is very jerky.
  • Dropped items fall through the edges of blocks. Dropped items that land on the edges of lava bounce off without burning; this effect continues into the Stripe Lands.
  • Fence posts are invisible.
  • Open fence gates are completely flat.
  • Doors and trapdoors render wider than normal.
  • Iron bars and glass panes render completely flat.
  • The supports of scaffolding are invisible.
  • Cauldrons and composters have completely flat walls and whatever is inside them will be stretched to fit the top.
  • The bottom part of hoppers are invisible.
  • Nether portal blocks are completely flat.
  • Flowers, sweet berry bushes, cobwebs and tall grass are much smaller than normal.
  • The first stage of cocoa beans is flat.
  • Chorus flowers render as full blocks.
X/Z ±4,194,304 (222)
  • It becomes extremely difficult to traverse the world on foot from here. Players need to use ender pearls, chorus fruit, elytra with fireworks, horseback, boats, or any method faster than five blocks per second, meaning moving in normal walking speed is impossible.
  • Entities less than half a block wide (such as items and silverfish) fall through the edges of blocks, but can still stand on the centers. This is likely because the hitbox corners on both sides round to the same coordinates, resulting in a "null" hitbox; however, it is not confirmed.
  • Status effect particles snap to the center of the player, causing them to bunch around the center of the screen.
  • Eyes of ender placed inside end portal blocks will be stretched to cover the entire block.
  • Piston bases are stretched to full block. If retracted, the front "flickers" between the head and base textures.
  • Crops and seagrass render on the edges of blocks.
X/Z ±8,388,608 (223)
  • All entities are on the edges of blocks. As a result, the player, along with other entities less than 1 block wide, always falls through blocks. The only entities that can stand on blocks from this point onward are boats, spiders, horses, iron golems, polar bears, and ravagers.
    • If only one coordinate exceeds this value, blocks still have collision detection from the side.
    • The player can still be considered "under" blocks, meaning that phantoms do not spawn. Thus, it is theoretically possible to travel to and from the Far Lands in survival using horses.
  • To fly in creative the player must sprint or look directly along an axis. The Speed effect does not work, due to MCPE-61425.
  • All blocks that normally render as partial blocks are either stretched to become full blocks, or squished to become 2-dimensional. The exception is a few blocks that render normally no matter how far out the player travels, such as chests and bells.
    • If both coordinates exceed this value, blocks become 1-dimensional, and are therefore completely invisible.
  • The blade of a stonecutter duplicates, with each blade appearing on the edge.

硬极限(X/Z ±12,550,821–2,147,483,648)

Coordinates Effects
X/Z +12,550,821 or -12,550,824 The Far Lands begin at these coordinates.
X/Z ±16,777,216 (224)
  • The floating point precision errors cause only blocks with even coordinates not divisible by 4 to render, and are stretched to 2 blocks wide. This phenomenon is known as the Stripe Lands.
    • Some blocks at other coordinates can render 2-dimensional, but not if they would be rendered on the end of a double-length block. In general, blocks only render if they are "exposed" to air or another see-through block.
  • 2D blocks are non-solid, even from the sides. However, ghasts, large slimes, and large magma cubes treat both 2D and 3D blocks as solid because they are more than 2 blocks wide.
  • The game does not properly register when the player is in water if the player' coordinates are divisible by 4. As a result, the player falls through water, is unable to enter swimming, and the fog is black or dark blue. However, water still causes the player to exit gliding, and boats still float.
  • The only method of transportation possible is by elytra.
X/Z ±30,000,000 It is impossible to teleport beyond this distance using commands in the vanilla game. Any attempts to teleport further will put the player back to this coordinate. Attempting to use any block placement command results in an error message. Despite this, it is still possible to use structure blocks and the /locate command.
X/Z ±31999872 Maximum coordinates reachable in the Overworld via Nether portal.
X/Z ±33,554,432 (225)
  • Horizontal block rendering stops completely, leaving only vertical block rendering in its place, marking the start of the Slice Lands.

Blocks whose sides are not "exposed", such as the naturally-generated water, are completely invisible.
    • At this point, the slices are 4 blocks apart, but the gap widths double for every power of 2.
    • It is difficult to place blocks from this point onward. The player must look at an existing block and extend it along an axis. The only way to generate blocks (to place on) without external tools is to use structure blocks.
  • Block rendering essentially stops completely in the Corner Slice Lands;[2] blocks are rendered as one-dimensional, and are therefore impossible to see.
  • Water becomes completely non-solid.
  • To move, the player must glide with elytra at a downward angle of approximately 45 degrees. Tridents are the only other entity that can move horizontally beyond this point. It is therefore impossible to teleport using ender pearls.
X/Z ±67,108,864 (226) All entities cannot move horizontally beyond this point. However, it is still possible to teleport using chorus fruit.
X/Z ±134,217,728 (227)
  • Maximum coordinates where generated structures can generate on mobile devices. However on Windows, structures continue to generate all the way to the 32-bit integer limit.
  • It is no longer possible to teleport using chorus fruit, marking the absolute edge of the world reachable without external tools.
X/Z ±1,073,741,824 (230) Slices of rendered blocks become 128 blocks apart, far enough for neighboring slices to be completely invisible with a low render distance.
X/Y/Z ±2,147,483,648 (231) The game crashes beyond this point, as this is above the maximum signed binary integer allowed for 32-bit systems, such as C++.

垂直方向极限

Like the X and Z axes, the game breaks at excessive Y coordinates. Since blocks cannot be placed above Y=255, block rendering glitches do not occur, but other effects do.

Many of these effects would occur at negative coordinates, but there is a barrier at Y -40. Beyond this entities can only move vertically using the "fall through the world" glitch. Thus the barrier can be avoided by teleporting past X/Z ±8,388,608. In addition, all entities, except players in creative, disappear in the void.

Y Coordinates Effect
Y ±1,048,576
  • Floating due to Levitation ±1 is no longer possible, and the effect particles turn black.
Y ±2,097,152
  • Floating upwards by holding the jump button with elytra and Slow Falling is no longer possible.
Y ±8,388,608
  • Status effect particles snap to the head, feet, and center of the player, resulting in a glitched animation assuming the player is in first person.
  • Slow Falling causes the player to be stuck in mid-air. Again, the particles turn black.
  • Flying upwards in Creative is no longer possible, although the player can still fly downwards.
  • There is a noticeable delay between when the player exits flight mode and when the player actually starts falling.
Y ±16,777,216
  • The delay described above is even longer.
  • Flying downwards in Creative is no longer possible.
Y ±30,000,000
  • It is impossible to teleport beyond these coordinates without external tools.
