Multiplayer Spawn
The article notes a 13 tile border, but later states the total protected area is 33x33. If there were a 13 block border around a 20x20 space this would give a protected area of 46x46, or with a 33x33 protected area the border would only be 6.5 tiles. Which number is wrong? --sirdrault 17:38, 14 March 2011 (CST)
 * I've never played multiplayer but a 6.5-block border would be kinda awkward. I'm going to assume the editor forgot he needed to add 13 twice. Alphap 22:09, 15 March 2011 (UTC)

As of 1.5_01, I can confirm that the protected area around the spawn is indeed 33x33. Additionally, there is a bug that allows you to place a block inside the protected zone when you're not an op: Place a block against a block that is outside the zone, and it is allowed. --coldelectrons

Spawn block
Is there an actual spawn block or do you spawn inbetween blocks? When I used the Compass, it would point in between 4 blocks instead of right in the center of one, but I cannot be sure based on this --Kris159 18:11, 16 November 2010 (UTC)
 * Based on where you stand after a spawn, there is an actual spawn point. The compass points to the northwest corner of your spawn block. I don't intend to sound catty, but that information is on the compass page which you linked to! JohnnyMadhouse 16:53, 16 November 2010 (CST)
 * Whoops, I didn't notice that bit when I read it. Northeast corner, do you mean >.< --Kris159 14:50, 18 November 2010 (CST)

Can mobs spawn areas that I build?
So basicly, that's my question. If I build my self a fortress and I leave it unlit and unguarded, will eventually mobs spawn into it and infest it, if I stay inside the boundaries that they can spawn? Vvp 21:00, 17 November 2010 (UTC)
 * Yeah. Those bad creatures will spawn any where that is unlit. --Scykei 02:11, 19 November 2010 (UTC)

One exception. If the ENTIRE floor is made of glass, or half-blocks (slabs/steps), baddies will not spawn :) Calinou 19:48, 23 March 2011 (UTC)


 * Which is a big waste of time. Torches work a lot better. Lol R ocĸetor talk  20:22, 28 March 2011 (UTC)

x=0,y=0,z=0?
What does this mean? If I look at a level.dat using LolEditor it says the Y spawn point is 64, and the X and Z ones are pretty much random. Is the 0,0,0 thing a hangover from a previous version of Minecraft and no longer correct? --DannyF1966 15:29, 24 December 2010 (UTC) Those are your coordinates, Y=How high you are, between 0 and 5 is bedrock. X and Z are the length and with coordinates. You can see those when you press F3 (No mod needed).--Jippiedoe 21:27, 16 March 2011 (UTC)

Spawn on Sand?
Can anyone confirm this? I spawn on dirt and stone all the time. Dragon of Fate 15:50, 15 January 2011 (UTC)


 * Update I'm in the process of testing it. Hopefully I'll finish this weekend. Pludrpladr 22:09 3 Febuary 2011 (CET)
 * Can this be confirmed? What were the results of this test? (If no-one responds in an hour, I'll check myself.) Darkid 23:40, 15 March 2011 (UTC)

In Single player, you always spawn in sand, this sand may be underground.. You may spawn underground then, rarely. In multiplayer, you can spawn on any block. You may find yourself in 1 block water depth (not 2 or more), or even on a tree. Calinou 22:49, 24 March 2011 (UTC)

I can confirm that this is false in 1.3. You sometimes spawn on grass. --Euryleia 16:51, 24 March 2011 (UTC)
 * Are there any other possible spawn locations? Stone, etc? Diamond, for obvious reasons, is (probably) not spawnable upon. Maybe with the right map, though. Darkid 20:18, 24 March 2011 (UTC)


 * Game only attempts to spawn you near sea level, don't expect to see diamond at spawn. Calinou 22:49, 24 March 2011 (UTC)
 * Well it's possible to be above a massive cave system, right? Surface caves and all? And spawn moves vertically by default, I believe. Might take some reverse-engineering of the randomness. Darkid 00:01, 25 March 2011 (UTC)


 * In the seed 'gargamel' you spawn on stone underground in a cave system. Hwever most worlds spawn on sand. I hate that! Now I can't spawn inside me house. R ocĸetor talk  20:25, 28 March 2011 (UTC)

the ultimate paradise
i found this awesome island but it was extremely far away from my spawn point and after a while (as normal) i died and i could not remember where that island was it was chock full of diamond and steel. do you think that there will ever be a way to make a movable spawn area in-game.


 * Yes, it's speculated beds will be them.--Jippiedoe 21:27, 16 March 2011 (UTC)
 * It's nearly here: 1.4!Darkid 00:18, 25 March 2011 (UTC)


 * Yes! I can't wait for it! R ocĸetor talk  20:26, 28 March 2011 (UTC)

Enemy Mobs

 * Have not been able to spawn on Sandstone. Can someone else confirm my finding? If this is the case, it's the first opaque block that mobs will not spawn on. - Goose 19:06, 18 January 2011 (UTC)

That could be the reason my loot generator isn't working... I'll try what happens if I use cobblestone floors.--Jippiedoe 21:27, 16 March 2011 (UTC)

Actually, I built my house out of sandstone and monsters spawn up there, as I have not lit it. I am not sure they are spawning on the dirt up there or the sandstone. Stinkbug22 20:17, 28 March 2011 (UTC)

Monsters (aggressive) spawn on everything except half blocks (slabs) and glass/ice and mid-air. This has already been proven. NB: I tried it myself. Kay, hope I solved this. R ocĸetor talk  20:21, 28 March 2011 (UTC)

Top of the Map
I have not seen neutral or hostile mobs spawn on blocks (grass and dirt specifically) at the upper limit of the map in Beta 1.3_01 Multiplayer. Can anyone confirm this for dirt or other blocks? Islandre 00:01 13 March 2011 (GMT)
 * This may be due to the algorythm of spawning based on layers... It's possible notch never added an upper bound to the algorithm, meaning that at levels of ~100 mobs require light level <0 to spawn.

I thought he removed that... --Jippiedoe 21:27, 16 March 2011 (UTC)

I thought it might have been because the space above the top blocks isn't in a chunk? In the Mob Spawning Science external link it says "Individual Spawn Loop: 8) Check that current L(i) is unoccupied, has spawnable ground below, and an empty space above. 9) If check fails, get next L(i) and go back to 8)."

Is the empty space above the top blocks empty spaces (blocks) or is it just space? Also this article is quite old, not sure if this is still how things work. Islandre 18:04 23 March 2011 (GMT)

They can't at layer 127-128, top of the map... Calinou 19:53, 23 March 2011 (UTC)

Monsters and Peaceful
In the Difficulty section of this wiki, it says that Monsters CAN spawn on peaceful, although they shall be removed immediately. In this page, it says that monsters CANNOT spawn on peaceful. The wiki is contradicting itself. If I get more support I'll change whichever one, or someone else may. Stinkbug22 20:16, 28 March 2011 (UTC)


 * Monsters (aggressive) DO spawn on Peaceful, and that is a fact. However, they are all removed instantaneously from the game, EXCEPT Slimes. In The Nether, Zombie Pigmen and Ghasts DO spawn, but they are instantaneously removed as well. Hope this helped. R ocĸetor talk  20:18, 28 March 2011 (UTC)

The code has been modified so you won't see ghost mobs or sounds, in 1.2_01.

Updated Spawning Science?
The info in this page, as well as the external link, point to the old mob spawning science thread, which states at the very top of the OP that it refers to how spawning science worked prior to the Halloween update. I remember seeing a newer thread on the forum, but I can't seem to find it. Anyone subscribed to it or able to remember the thread title? >.< Genshou 17:33, 15 April 2011 (UTC)

OP and others discuss the updates later in the same thread. Not sure if it's fully up to date now. Islandre 23:52, 18 April 2011 (GMT)
 * Here is the thread I found: http://www.minecraftforum.net/viewtopic.php?f=1020&t=117374
 * On pg. 2 are some density maps that show spawning/despawning over a 10-hour (36,384 second) period on a flat map. There's another thread I read that has a bit more scientific explanation of exactly how mob spawning is sorted procedurally: http://www.minecraftforum.net/viewtopic.php?f=1020&t=147976


 * I think the spawning page could use some updates, since it's been out of date as of Halloween. If I don't get to it early on in this upcoming week, feel free to remind me via my user talk page ;D (Genshou 05:35, 15 May 2011 (UTC))

Mobs in caves
Mobs spawn in the 144 x 144 area around the player, but what about the height? If the player is on the surface, will monsters spawn in the caves underground? Does it matter how deep (or high) they are? --Joshua Issac 04:37, 26 April 2011 (UTC)
 * Pretty sure it doesn't. Mobs seem to spawn at all altitudes within that 144x144 area. - Alphap T ~ C 05:25, 26 April 2011 (UTC)

Spawn Point Changed
I have a second base very far from my first that I reached without generating the chunks in between by travelling through the Nether. I rested in a bed in this second base, then moved the bed and died. I spawned in a new location near this second base instead of my original spawn point near the first base.

Passive mob limit
I think the limit is higher than 15. Reasoning being that you can have a pack of up to 20 wolves before monster spawning stops. Nosrepa 03:20, 21 May 2011 (UTC)

I think the limit is around 30 personally, at least in SMP. I tried the //butcher command many times (I said this above maybe :P), it says "Killed 26 mobs." Sometimes 27 or 28. Unfortunately I can't read the code. C ali nou - talk × contribs » 08:04, 21 May 2011 (UTC)

I talked to tramsam in IRC and he said the limit is still 15, but that squids do not count towards that limit. There also could be an exception for chickens, as you can spawn those yourself via eggs Nosrepa 05:57, 23 May 2011 (UTC)

sunlight needed?
Passive mobs spawn on grass blocks with light level >9, right? Does that light HAVE to be from the sun, or can passive mobs spawn inside buildings if there is grass and light? And if it DOES need to be open to the sun, do glass roofs count?Wandergirl108 03:12, 22 June 2011 (UTC)
