Question about drops
Is this to say that, if you die and drop a bunch of stuff, and respawn far away from it, it won't despawn until you go back and enter that chunk? How long after entering a chunk do mobs begin to spawn? Is it essentially pointless to plant trees in areas you don't regularly visit? Sorry for all the questions, this is just very different from how I perceived the game working. MrMatthew 20:55, 7 October 2010 (UTC)


 * Items despawn after five minutes unless you're far away from them. I don't know the answer to the other questions. I think it's time for some experimenting! :D –Preceding unsigned comment was added by PurpleKiwi (Talk&#124;Contribs) 8 October 2010. Please sign your posts with


 * You are always in a 9x9 chunck square, with the chunk you're standing on, and 4 loaded infront, 4 loaded behind and 4 to either side of you. Monsters can spawn the second their chunk is activated (Within the 9x9 area around you) and trees and crops will only grow it you are within not 9, but 5 chunks away (As you're at the CENTER of the 9x9 square, not the edge), so anything further than 80 blocks away will never grow and monsters won't spawn, though I'm pretty sure it's the opposite with item decay. Only items further than 80 blocks/5 chunks will therefore decay so you will always have to run to get your items, unless your spawn is close to where you died. I could be wrong about the decay, and it may be the other way around... I forget =O.o= Reziah 07:15, 19 April 2011 (UTC)
 * I believe that dropped items don't get updated unless they are within your 9x9 chunk. Once I was exploring and got lost so I committed suicide by jumping off a mountain overhang. I had a lot of resources so I wanted to find where I died when I respawned. It probably took over half an hour of searching before I resorted to using map viewers to find where I died. My items were still there.--Lunt0er 22:03, 23 April 2011 (UTC)
 * I believe Notch himself said that there's a 5-minute timer on dropped items which pauses if they aren't within that 9x9 chunk box. My personal experience has confirmed this many times as well. - Alphap T ~ C 22:31, 23 April 2011 (UTC)

Chunk Load distance
I know I've seen somewhere where someone said either the radius or diameter of chunks that are "nearby" enough to load. Does anyone have this information still? My Google-fu is weak tonight. Cjc343 11:21, 23 October 2010 (UTC)


 * 128, I think. I read about that in the forum somewhere. PurpleKiwi 01:42, 24 October 2010 (CDT)


 * In Talk:Items, someone says the time is about 5 minutes. We’ll have to find out if we can get the chunk (on which some items are) to be saved to disk, then come back and see if the items still despawn. ‒ Flying sheep 13:14, 4 April 2011 (UTC)


 * 9x9 Chunks around you. You being in the center with 4 chunks on all sides (Including diagonals). That means if you're in the center of a chunk, things are loaded 70 blocks around you (4 full chunks loaded plus half one chunk that you're in the center of, minus 2 as you'd be standing on the corners of 4 blocks). This also means the furthest away you can be from a block in memory (Not including height) is 80 blocks, on the very corner of a chunk. Reziah 07:25, 19 April 2011 (UTC)

Isn't it 17x17 chunks loaded around a player, not 9x9? Benjaminkc 20:31, 4 October 2011 (UTC)
 * Ah, the page has been updated to say that it's variable based on view distance and single/multiplayer. If someone knows the radius per fog setting, a little table would be nice.  Benjaminkc 21:04, 5 October 2011 (UTC)

Chunk dimensious
Hi

is a chunk really 16 x 128 x 16, which is suppose is X x Y x Z? From the picture i would say it's 16 x 16 x 128. –Preceding unsigned comment was added by Knochi (Talk&#124;Contribs) 09:40, 17 November 2010. Please sign your posts with


 * According to Minecraft_map_format_(NBT), the Y coordinate is height, not Z. --DannyF1966 03:43, 17 November 2010 (CST)


 * Yeah. Minecraft reverses the usual meanings of "Y" and "Z" for some damn reason. Phasma Felis 06:55, 25 December 2010 (UTC)


 * Actually, X and Y were always Length and Height. Think back to 2D games, they had X and Y, Width and Height. The third dimension was added, so Z is always depth. Reziah 07:06, 19 April 2011 (UTC)


 * X and Z is the flatland in which the player walks on. X is Length, Z is Depth. Y is the elevation from bedrock. Ah, I love number cubes. --R ocĸetor talk  07:12, 19 April 2011 (UTC)


 * It depends on the developer and most modern engines allow you to change it. X, Z, Y is the most conventional method though and most don't find it easier to move to a different order. –Preceding unsigned comment was added by 99.22.209.41 (Talk) 12:57, 16 March 2012. Please sign your posts with

Chunk activity question
Is all activity stopping when not around ones 9x9 chunks? What about minecarts driving out of the active chunks? Do they continue or just when the inactive chunk they entered is reloaded (by getting into ones 9x9 area) or do they even just stop? I have experienced that neither a furnace works when nobody is around, nor grass is growing. Could also have been because nobody was logged in during this time. Don't know if it would have continued growing/smelting when another player had logged in, but further away than those 4/5 chunks. Enudoran 14:58, 19 May 2011 (UTC)

Dungeon=unlimted supply of hostile mob drops?
I think this is what this does I found a creeper spawner and now I have a total of 70000 TNT's I don't really think this is fair because getting Gun-powder should be more difficult. –Preceding unsigned comment was added by Dusty01 (Talk&#124;Contribs) 15:17, 19 May 2011. Please sign your posts with
 * You should have put this up on either monster spawner or dungeon, creeper spawners do not happen naturally, but while it makes it easy to get a lot of bones or TNT, it also makes them very dangeris. Timberdoodle 16:03, 19 May 2011 (UTC)

First of all, the person above is correct. Creeper spawners do NOT happen naturally. Second, if we assume that they DID exist, and each dropped 1-2 for an average of 1.5, to get the 350,000 gunpowder needed for that many TNT, you would need to kill about 230,000 creepers. With a spawn rate of about 1 every 5 seconds, that would take almost one million seconds, which is almost two week in real life time. Just saying, but what you said most likely could never happen, even if there WERE creeper spawners. 72.209.199.2 18:31, 14 July 2012 (UTC)

Slimes
Does anyone think slimes should spawn in all chunks, not just 10% of them? I need slimeballs. Jedi in, um, I forgot. 15:40, 12 July 2011 (UTC)
 * This site is for information, not for suggestions. Also, they spawn in somewhere around the 50% mark of chunks, but it doesn't appear to be entirely random, but instead working in groups. Shellface 15:50, 12 July 2011 (UTC)
 * That is completely wrong. There is exactly a 1 in 10 chance that a chunk spawns slimes. Escortkeel 10:03, 3 August 2012 (UTC)

Despawn
How much blocks from a monster exactly must the player go away to cause the monster to despawn (horizontally and vertically)? Xeoxer 12:18, 1 August 2011 (UTC)

After a minecraft update, do new blocks generate in new chunks?
this isn`t answered anywhere I can find, so I decided this would probaly be the best place to ask it.--Icecat can haz cool signature? 23:31, 25 September 2011 (UTC)
 * Yes. New chunks are generated using the terrain generation algorithm.  Thus, chunks that have already been generated do not get new stuff, on account of not being regenerated, and new chunks do get new stuff, on account of being generated with the new terrain generator.

A different Kind of Chunk Error
So here I am playing with the TMI mod on, a 111 stack of boats in hand and a map (that I soon learned I couldn't view while riding a boat.) I'm trying to find a suitable place that's not in the midddle of the ocean to build. I'm traveling West (towards the sunset) at full speed on a boat. I'm noticing the chunks are having trouble keeping up with me, so I wanted to see if I could outrun the generator. I'm pretty close I have to say, but suddenly it catches up, but an odd formation is formed. I'm calling it the Inverted Chunk Error, and you'll see why. I have some screen shots:


 * http://img801.imageshack.us/img801/5812/chunkerror1.png - Note, this is the 'Back/West' wall of the Inverted Chunk Error, where I'm facing east. I did not come this way at this angle at all to meet the chunk.


 * http://img80.imageshack.us/img80/2862/chunkerror2.png


 * http://img842.imageshack.us/img842/295/chunkerror3.png - This is the North side of the Chunk, and to the right is a single, tinier Chunk that was generated with the larger mountain chunk.


 * http://img98.imageshack.us/img98/9138/chunkerror4.png - At this angle, you can see the see floor. You can also see how the Inverted Chunk Error goes all the way down to the see floor, probably past that.


 * http://img821.imageshack.us/img821/4046/chunkerror5.png - Eastern side, facing West. I can now see that this is was obviously supposed to be an Extreme Mountain Biome, odd, yet funny, how the game generated this in the middle of an Ocean Biome. Also, in the bottom corner, you can see that there is a cave. The water wasn't flowing into that. I have another screenshot of another cave that shows it better.


 * http://imageshack.us/f/543/chunkerror6.png/ - What is this, a Farlands Wannabe? This is the angle I came at this chunk, not the exact place, but this nearly-solid wall was the first thing I saw, followed by a 'Wow.'. Oddly enough, there are waterfalls carved into the sheer wall, but a water-spring in that cave over there (in the top, left corner) the water will not flow out.


 * http://img135.imageshack.us/img135/3057/chunkerror7.png - Hard to understand/believe that this was generated in the middle of nowhere. Game, our race has ended, you win. Obviously, mobs are able to walk on it, so it isn't a 'normal' Chunk Error.


 * http://img580.imageshack.us/img580/2793/chunkerror8.png Here is a cave that was carved into this chunk. You can clearly see in this picture that water isn't flowing into it.


 * http://img651.imageshack.us/img651/1517/chunkerror9.png On the other side again.


 * http://img716.imageshack.us/img716/2880/chunkerror10.png Well, I am able to walk inside this chunk. Here I am, inside another cave that was generated. Again, no water flow.


 * http://img8.imageshack.us/img8/866/chunkerror11.png And here's the outside of it.

The onlything unusual about this is the generation. By all appearances, it's a completely different biome, but other than that, the land is normal, mob-spawning is normal, and I can even walk and build on it. Speaking of that, it appears the water will flow into the caves if a block around it is modified, which I expected. I put a ladder near one of them. Perhaps if I were to travel at high-speed across a Mountain Biome I'll suddenly run into a see Biome chunk strip, doubt it though, and I plan to stay here anyway.

So guys, what do you think about this? This is the most fascinating thing I'm found in Minecraft lately.--DemonSlayerThe3rd 20:49, 4 October 2011 (UTC)
 * There is nothing fascinating about this, sorry to burst your bubble. You've started a world in an old version and then upgraded to a new version (therefore a new world generation) which messes up the borders of your current world. Alternatively, the seed has changed (causing new generation). And before you say that it's a new world, there's a semi-bug where if you create a new world with the same name of an old one some chunks won't get deleted completely and this kind of stuff happens. --Wizjany 20:59, 4 October 2011 (UTC)
 * Not true, this is a brand new 1.8.1 world, I literally just made it 20 minutes ago, with a completely different name from any other world I've created. None-the-less, this type of error should also be noted in the page, since I see nothing in the article regarding this specific type of chunk error.--DemonSlayerThe3rd 21:40, 4 October 2011 (UTC)

Questions
Is there a program that will load chunks for you. So i wanted to load all chunks within 20 chunks of my position and it loads them without you have to walk to each on??? –Preceding unsigned comment was added by 75.174.36.2 (Talk) 00:23, 8 October 2011. Please sign your posts with

Question about chunk loading
I have a question about how things are loaded in multi-player. It says here that 32,768 blocks are loaded per chunk, and that 441 chunks are loaded when a player logs in.

If every block was sent as a byte (up to 255 unique blocks), that would come to a total of 14,450,688 bytes, or 13.78 megabytes on login ; which is a HUGE amount for even modern internet connections to send to every player. Am I missing something here? –Preceding unsigned comment was added by 70.70.194.197 (Talk) 07:09, 8 January 2012. Please sign your posts with

Ore Probability
Is it safe to say that there isa near-100% chance of finding Diamonds in a chunk? I'm currently quarrying a 64x64 area and am hoping to find some diamond. I also need to point out that there are the 4 full chunks (in a snow biome, can see the chunk outlines), so the oddsof me finding 4 formations are what? LightRod 01:03, 30 March 2012 (UTC)
 * It's possible for a chunk to contain no diamond ore, if it tried to generate in the same space as a cavern or lava pool. However, on average (over several thousand chunks), there's about 3 diamond ore per chunk. So a 64x64 quarry (4x4 chunks) should produce around 45-50 diamonds, more if you explore caves as well. -- Orthotope 02:31, 30 March 2012 (UTC)
