Mob Spawners (or Monster Spawners) are unique Blocks with a transparent, black, cage-like, lattice structure found in various locations. Inside the block are flame particles that don't give off any light and a miniature spinning version of the Mob it spawns. This will slowly increase in speed until the next group of mobs is spawned. When mined with a Pickaxe, they drop experience, but it cannot be obtained, even with the Silk Touch enchantment. In Minecraft: Bedrock Edition, they are available in the Creative inventory. In other editions of the game, the only way to obtain the block is by using commands.

They are one of the few blocks not obtainable in Creative mode (except in the Bedrock Edition) unless commands are used. It is possible to get this block through the command, but it will only spawn pigs, even with the correct details. However, the command can be used to place monster spawners with a mob of a player's choice, provided that it is used with the correct NBT data. In the Minecraft: Pocket Edition from Update 0.9.0 and in the PC Edition, starting with snapshot 14w28b, the mob spawned can be set by using a Spawn Egg on it.

Behavior

A mob spawner will summon mobs, provided there is enough space for the mob to be generated, and the light level within the spawning radius remains below seven. Mobs are created within an 8x8x3 high area centered around the spawner's lower northwest corner. Note that mobs can spawn in any dark space within range, even if the spawner is fully lit. The spawner will only spawn mobs if a player is within 16 blocks of it. A common trend among seasoned players is to create mob traps around mob spawners for an easy way to gather that mob's resources with little or no danger to themselves.

Spawn List

  • Dungeons — The most common area to find monster spawners. The spawners found in these areas can spawn Zombies, Spiders, and Skeletons. Zombie spawners will appear 50% of the time, while the other two have a 25% chance of appearing.
  • Abandoned Mineshafts — These areas contain many useful items, as well as Cave Spider spawners.
  • Strongholds — These areas contain the portals to the End, along with a single spawner in the portal room that spawns Silverfish.
  • Nether Fortresses — Extremely large structures that have useful items found in the Nether; the spawners they hold spawn Blazes.
  • Woodland Mansions - Rare structures found in roofed forests, there is a secret room that occasionally generates which has a spider spawner inside of a said room.

Note:Monster spawners can only be obtained through mods and hacks, such as "TooManyItems", or by using the command.

Usage

Spawners can be used to make very effective "Mob Grinders", as they spawn more mobs faster when a player is in the spawner's vicinity. The best way to make one is by first make a large dark room around the spawner, then place down a "floor" 3-5 blocks below the spawner. Next, on the "floor", place down Water so it "funnels" the mobs that spawn into a hole in the "floor" which will lead wherever a player wants it to. Once the mobs are all gathered in the desired location, a player can either kill them manually or kill them with a Redstone contraption, and finally harvest the experience and items the killed mobs dropped.

Another option is to simply not place down any water and allow the mobs to take fall damage, which allows a player to kill the mobs more easily from a safer location. It is advised to light only the bottom of the pit. That way, the player will be less likely to encounter mobs other than the ones produced by the spawner.

Trivia

  • Mob spawners have an ID of 52, and they are named "Monster Spawner" in-game.
  • Even though the spinning mob figure is much smaller than the actual mob, Ghasts, Ender Dragons and Giants are too big for the spawner to be seen.
  • Monster spawners can spawn up to four mobs at once.
  • Very rarely, a monster spawner can be found in out-of-the-ordinary locations.
  • In the Minecraft XBLA (before the Christmas update in 2012), mob spawners would only show pigs, but they would spawn things other than pigs.
  • Blaze spawners are the only type of spawners that are found naturally in the nether.
  • Monster spawners were added to Minecraft Pocket Edition via update 0.9.0.
  • Many players searching for the command that give them a mob spawner. The command is:
/give (playername) minecraft:spawner (amount)

Example:

/give killer1201 minecraft:spawner 64

Update for Minecraft 1.9: the syntax for the mob spawner commands have been changed starting in Minecraft 1.9

You can read the rest of this blog post for all the examples, but the main key difference is that the tag has been removed and you need to do instead, replacing "EntityIdHere" with the entity ID you want (Zombie, Skeleton, PigZombie, VillagerGolem, etc.)

So, for the /setblock command:

Old way:
New way:

And for the /give command:

Old way:
New way:

So when you see examples below, translate them into the new format for Minecraft 1.9. I may eventually write a new version of this blog post that contains only 1.9 commands, but for now you'll have to rewrite them manually.

Edit 2: there seems to be a bug in 1.9 where a spawner given with the command will only spawn its monster one time before reverting to a pig spawner. The seems to be the culprit; when the block is placed it gets initialized to a list that only includes pigs. The list is supposed to be empty by default, so explicitly setting it to empty seems to work:

/give @p mob_spawner 1 0 {BlockEntityTag:{SpawnData:{id:Skeleton},SpawnPotentials:[]}}

The original blog post follows.

--Updated on 3/17/2016


Minecraft 1.7 added the commands , , and an extended syntax for , so that you could summon any entity, and attach a ton of NBT Tags on it to control attributes like what equipment it's wearing or whether it's invulnerable. ;)

I was excited about this because not only could I spawn an Enderdragon in the overworld (this never ends well), but it would open up the possibility to just give myself custom monster spawners, like those typically found in a zombie/skeleton/spider dungeon.

Update: since writing this I found the syntax for giving a mob spawner with . Example:

/give @p mob_spawner 1 0 {BlockEntityTag:{EntityId:Skeleton}, display:{Name:Skeleton Spawner}} This gives a Skeleton Spawner in your inventory. The stuff is just to give it a custom name, otherwise it will call itself "Mob Spawner" in your inventory. If you're gonna carry multiple spawners, the names will help differentiate them. Everything inside the part are the same tags from the examples below.

Now back to the original post...

Pictured above are your "naturally occurring" monster spawners along the bottom: Blaze (in Nether Fortresses), Skeleton, Zombie, Spider, and Cave Spider (in abandoned mineshafts). I've also created spawners along the top for: Magma Cube, Slime, Zombie Pigman, Creeper, and Enderman.

The basic command syntax is along these lines:

/setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:Zombie} Replace the value for for any other valid entity. There's a list of Entity IDs on the Minecraft Wiki. You can create a monster spawner for pretty much every monster in the game, including the bosses like the Enderdragon and Wither.

/setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:EnderDragon} /setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:WitherBoss} Things to watch out for: the Enderdragon will destroy every block it touches except for Bedrock, Obsidian, and End Stone (a.k.a. the only three types of blocks that naturally occur in the End Dimension), so it will destroy its own spawner, and if you create one in the overworld or the Nether, it will ruin everything it touches. You can mitigate this by turning off monster griefing with the command .

With this command you can also create a spawner for the Giant. This monster has been in the game for ages but never officially used. It's a super-huge zombie. However, I couldn't get this spawner to actually create a Giant for me. :( Your mileage may vary. You'll probably be better off summoning it directly with .

/setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:Giant}

You can also create a mob spawner for horses! (edit/warning: this worked for me when I originally wrote this post, but others have reported that horse spawners tend to crash their games. I can reproduce this behavior now too in Minecraft 1.7.10 and a few others I tried (1.7.9, 1.7.2). There's a Minecraft bug ticket for this. YMMV. It seems to work in snapshot 14w31a (screenshot) so may be fixed for 1.8)

The zombie and skeletal horses aren't naturally occurring in-game, and they cannot be tamed normally like other horses. You'll want to make sure the "Tame" flag is set when spawning these so that players can ride them. They can equip saddles, but not armor.

Zombie: /setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:EntityHorse,SpawnData:{Type:3,Tame:1}} Skeletal: /setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:EntityHorse,SpawnData:{Type:4,Tame:1}}Again, warning: horse spawners with SpawnData may crash your game. It's a known bug in several versions of Minecraft. If this happens, and your game managed to save the world before the crash, so that it instantly crashes again when rejoining the game, you'll have to use a third-party tool like MCEdit to delete the offending spawner.

That "SpawnData" attribute from the previous command is how you can attach NBT data to the spawned entity. Horses take a Type attribute and Tame, among some others. You can see all the relevant NBT tags at "Chunk format" on the Minecraft Wiki.

Here's a more advanced command that creates a Zombie spawner where the zombies are all equipped with Diamond Swords. I found this one from the Minecraft forums (I don't know or care too much about the NBT format; I usually just create simple spawners as listed above in this post).

/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {EntityId:Zombie,SpawnData:{Equipment:[{id:276,Count:1}]},SpawnPotentials:[{Type:Zombie,Weight:1,Properties:{Equipment:[{},{},{},{},{id:46,Count:1}]}}],SpawnCount:2}Note: You'll have to paste that into a Command Block () because the command is too long for the chat console. Attach a button to the command block with Shift+RightClick, push it and the spawner will appear above the block.

These tips are REALLY useful!

these commands wont work on my computer

these commands wont work on my computer

Hey im new in minecraft. I play since 2 weeks. Now i want to summon monsterspawners and was searching for the commands. I tried ur /setblock ~ ~ ~ mob_spawner 0 destroy {EntityId:EntityHorse,SpawnData:{Type:3,Tame:1}} but it crashed my world total. Now i cant back in longer as 5 sec. Do u have an idea. Sry for my english ;)

Thank you SO much. I couldn't find this Info ANYWHERE else :D

I cant get it to work for a cow... any help?

/setblock ~ ~ ~ mob_spawner 0 destroy {EntityId: Cow}

It sort of worked, but no image appeared in the spawner, is this a bad thing?

This is awsome it actually worked i love this page thx to whoever made or build this page or blog or vlog

Any idea how to place a custom mob spawner using multiplayer worldedit? I play on a server with a world edit plugin and I want to place down a spawner for diamond blocks.

@anon no space between colon and cow. /setblock ~ ~ ~ mob_spawner 0 replace {EntityId:Cow} that'll work for ya

@need a spawner The only way I know of to make an item spawner is with MC edit. You toss the item on the ground from your inventory, save and exit. Open MC edit, highlight the item (shown as an invisible block), click filter, open the drop down menu, click create spawner, check the box and click filter. Save, re-enter your world and the spawner will pop out that item. 1 - 4 every about 20 - 30 secs. Set up Hoppers under it to a chest and let it fill up.

I knew how to do this sort of, but the spawner would stop Working after a while, now I fixed it thanks to this page!

Is it possible to make a super charged creeper

To make a spawner for super charged creepers:

/setblock ~ ~ ~ mob_spawner 0 replace {EntityId:Creeper, SpawnData:{powered:1}}

how do I get a magma cube and zombie pigman

How would I do this to spawn, say, gold nuggets?

WOW!! The best commands ever!! :)

DON"T USE THE SET BLOCK COMMAND FOR THE SKELETAL OR ZOMBIE HORSE SPAWNERS!!!!!! it will crash your game! I used it, now (like the guy who said he can't stay in his game longer than five seconds) it will crash your world every time the mobspawner block renders. If there is a fix for this!!! PLEASE LET ME KNOW!!!

What version of the game are you using? I took those screenshots of the skeletal/horse spawners in-game on one of the 1.7.x versions and it didn't crash for me. Are you on the 1.8 snapshots? Those are highly unstable so don't be surprised when things crash snapshot worlds (recently, item frames crashed worlds in the snapshots).

Use MCEdit to remove the spawner from the world if you need to fix it.

I cant get it work IronGolem, can help?

Thanks You, Nice~ Its Work

Is it possible to let spawn colored sheep?

That'd product magenta sheep. See data values for a list of colors and their numbers.

I must be doing something wrong. I keep placing spawners that are empty and don't produce anything. I'm running 1.7.9.

the super power creeper wont work

I have no idea how you people can have trouble copying and pasting these commands. They all work on Minecraft 1.7.

  • Make sure you're on Minecraft 1.7 or higher

  • Make sure you're on Minecraft 1.7 or higher

  • They don't work on Minecraft 1.6

  • When you select the command to copy it, make sure that you ONLY select the command, the full command, and nothing BUT the command.

  • This means the at the beginning all the way up to the very last should be highlighted before you hit Ctrl-C.

  • If you didn't highlight enough of the command, so some 's are missing, it's a syntax error, the command won't run right in Minecraft.

  • If you copied too much (like your hand slipped and you copied 2 more sentences of text from the page), syntax error, command won't work right.

  • Some commands are TOO LONG to paste into the Minecraft chat console. After hitting Ctrl-V, if the command doesn't end with the same symbols you saw on the page, it's TOO LONG. Test it by typing "AAA" at the end, if it doesn't let you type anything, the command is too long.

  • IF the command is too long, give yourself a Command Block with , replacing with your Minecraft username, without the or . For example my Minecraft username is caskir, so I type

  • Be in creative mode and make sure you're the server OP and place the command block, then right click it, paste in the long command, hit OK, then attach a button or something to your command block to activate it (hold down shift and right-click to place the button). Then right click the button to activate the command block.

Snow Golem's entity name is SnowMan.

As mentioned twice so far on this page, consult the Entity IDs wiki page for the list of all entity IDs.

In case anyone else is too lazy, here are the "tricky" entity names that don't match the in-game names.

  • Wither Skeleton is still a (but with as its SpawnData)
  • Zombie Pigman is a
  • Magma Cube is a
  • Wither is a
  • Mooshroom is a
  • Snow Golem is a
  • Ocelot is a
  • Iron Golem is a
  • Horse is an

Other mobs that have a space in their names: just remove the space, capitalize all words. Cave Spider is a , Ender Dragon is an , etc.

So, I figured out what I've been doing wrong. The script is case sensitive. Thank you for showing me how to do this. I log it.

i made a snowgolem and irongolem spawners with 10 zombie spawners in a areana! it was awsome!

how do i spawn a cave spider spawner ??

i have placed down spawners for everything from primed tnt to wolves, but none of them spawn anything. they have the entity spinning in the middle but nothing comes out.

The spawner still follows the normal spawn rules for the entity inside it. So for passive animals like cows and sheep, there has to be grass around the spawner and a high light level (or be facing the sky). I'm not sure if wolves have an extra requirement of needing to be in a certain biome like a taiga forest though. Hostile monsters need darkness to spawn.

PrimedTnt has no natural spawn conditions so good luck getting the spawner to produce them. You may need some extra NBT tags to get that to work.

well this didn't work

i had a zombie sword spawner, then i blew it up; then i re-summoned it and it was a tnt-zombie spawner!

:D

can you spawn stacked entities?

thank you so much helped alote.

@powercamel:

Here's an example spawner that will produce Skeletons riding on top of Skeletal Horses. You'll need to paste this command into a command block, because it's too long to paste in the chat console.

Screenshot: http://imgur.com/Rz67PZP

With that specific command, the Skeleton won't be equipped with a bow. Here's a version that equips the Skeleton with his standard bow:

Also note, the mob on the bottom (the skeletal horse in this case) dictates where the stack of mobs wanders off to. So the skeleton jockey won't run after the player, it will just wander randomly and shoot you with its bow, because the horse's AI is to just wander randomly.

The only "neutral" mob whose AI is able to be taken over by its rider is the Chicken, when being ridden by a Baby Zombie.

If you place a big tower of fences on top of giant spawner it looks like he is pole dancing! ;)

can you have a spawner that gives a zombie on a pig?

Zombie riding a pig (untested, should work, might need to paste in a command block):

The zombie won't control the pig's movements though. The only mob whose AI can be overridden when riding is the chicken, and only when being ridden by a baby zombie.

how can you get a enderman to ride on another endermans back?

these tips helped me spawn a skelatan horse which was EPIC!!!!!!!

plz tell me how can you get a enderman to ride on another endermans back?

Look at the Minecraft wiki and/or look at the dozens of examples on this page and figure it out.

Untested:

hmm how do we spawn a zombie with full set diamond armor ??

Help me with the wither skeleton spawner I put spawn data but it always fails please help!!!!!

Oh and a chicken jockey spawner too. (Maybe a pig jockey) Note. Chicken jockey is baby zombie on a chicken. And pig jockey is the same just a baby pigman instead of baby zombie.

@Tommy:

  • Wither Skeleton Spawner (no weapon)

  • Wither Skeleton Spawner (with stone sword)*

  • Chicken Jockey

  • Pigman Jockey*

* The wither skeleton w/ sword and the Pigman Jockey will need a command block because the commands are too long to paste into chat. You'll want to change the beginning of the command (the part) to summon the spawner somewhere else so it doesn't replace the command block itself, i.e. will make the spawner appear on top of the command block.

Ok thank you. This will help for my mob arena and my redstone map.

I'll try it out right now.

If you're redstoning, you can also use the command to instantly summon desired monsters instead of creating mob spawner blocks. It might be a better option for a mob arena depending on your requirements (I'm imagining one arena room area, and some redstone to summon mobs in waves of increasing difficulty).

i.e. the standard wither skeleton w/ stone sword using the command:

Just take the NBT tags from the "SpawnData" part of a mob spawner and put it at the end of the /summon command.

what would the command for a zombie with enchanted armor and weapon be i can't figure it out

Hey, I've seen that people are having trouble and I KNOW WHAT THE PROBLEM IS!!! They type / to open up the chat bar, then they paste. But the problem is that then there are TWO /es! So that is probably what your problem is.

Now, for kirsle, is it possible to make a giant-riding-a-ghast spawner? IF SO, tell me what I should say.

Something like this, in theory:

But since the Giant has no valid spawn conditions naturally, it might not spawn anything from a mob spawner (I couldn't get normal Giant spawners to produce anything). Some other NBT tags might work but I don't know which ones for sure. I saw somebody who made PrimedTnt spawners that summoned the TNT a good distance away from the spawner (inside a "volcano" in fact), and PrimedTnt doesn't spawn under any natural conditions either, so there should be some way to force spawning.

Tile Entity Format

The command can for sure summon what you want. Depending on your needs you might be able to just build a redstone contraption with a command block.

So I'm trying to make a custom Pig spawner for my mini game world and unfortunately it refuses to spawn. The problem is not in the command because when I change the entity type into something hostile (like a zombie or a skeleton) the command works perfectly and to all the permitters that I set up. This is the command I'm using at the moment and if anyone could tell my why it refuses to spawn that would be very helpful, thanks! (Here is the command: /setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {EntityId:Zombie,SpawnCount:2,SpawnRange:3,RequiredPlayerRange:64,Delay:10,MinSpawnDelay:10,MaxSpawnDelay:100,MaxNearbyEntities:2} and i tried running on multiple versions and none worked

Normal spawn rule requirements apply to mob spawners.

Animals like pigs, sheep, chickens, horses, they can only spawn on grass blocks with a high light level (or facing the sky).

It's why in the original blog post, I switched from a desert superflat to a plains one to show screenshots of the horse spawner. The mobs wouldn't spawn in the desert due to the lack of grass.

how do i get the giant to work and is it possible to get a pig with armour???

I decided to look into it finally. From the wiki:

In the code, giants need to have a light level both less than 8 and greater than 11 to spawn, but since that can't happen, they don't spawn from monster spawners. However, this spawn condition can be bypassed with a custom spawner, if it attempts to spawn an entity with valid spawn conditions riding a giant.

So a giant won't spawn by itself from a mob spawner since its spawn conditions are impossible. But spawn something else that's riding the giant and you can do it. Something like,

And, pigs can't wear armor no matter what, so a mob spawner can't spawn a pig with armor. Same goes for all other mobs except for skeletons, zombies, and giants.

is it possible to make a pit riding a pig riding a pig

i mean pig riding a pig riding a pig

how to spawn an pig riding an enderman riding an villager riding an enderdragon riding an steve riding an giant

how to spawn an giant with armor my name in minecraft are porfen

what the heck i did all spawners but they just don't work!! they don't spawn HELP ME PLEASE

Ok my name is Anonymous and I love Minecraft. I play it neally every day so I think I should know what I am doing. Ok get a command block and type /see thru (do not do yours!) (ONLY WORKS ON MULTIPLAYER) then click DONE and put a redstone block next to it and it should make you be able to control someone elses body WITHOUT MODS or PLUGINS! Only works on 1.7.4:1 (First snapshot of 1.7.4)

The skeletal horse spawner crashes your game every time you enter the world, after you've spawned it in :(

I once tried putting a painting in a spawner... it didn't work out to well... CRASH.

Just now tried: /setblock ~ ~1 ~ mob_spawner 0 replace {EntityId:"EntityHorse",SpawnData:{Type:4}} Crashed: Yep. Version: 1.7.10. There's nothing wrong with this, right?

Confirmed that horse spawners do crash the game in 1.7.10.

Here's a Minecraft bug ticket about it for more information. Hopefully it'll be fixed soon. ;)

In the mean time you can use command blocks to the horses if you need them for something. Mob spawner-like behavior could be accomplished by a redstone circuit that uses to find players within a certain range of a coordinate, then some repeaters for delay, then the horse.

Update: tried the latest snapshot (14w31a) and spawned a skeleton horse spawner and it didn't crash the game.

Screenshot

Command was the typical

Hopefully this means they'll be fixed for when 1.8 is released. :)

Note In MC 1.7.9 the command to place a spawner for Zombie or Skeleton Horse's will Crash the Client every time you load the Chunk The spawner is in dose not crash the server Just the Client for MC 1.7.9 in a vanilla MC server or a Bukkit Server in Both server types the Client will Crash when you try to Make a zombie/skeleton horse spawner!

Love the page, really useful. The command for the zombie carrying the diamond sword actually seems to work fine if you cut it short like so: /setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {EntityId:Zombie,SpawnData:{Equipment:[{id:276}]}}

this way you can paste it directly into the chat console. hope it helps!

how do u make a donky spawner?

I have looked and I have seen it before but how do you get multipul mobs in 1 spawner

ITS OVER 9 9 9 9 9 90000000000000000000000000000000000000000000

I cant seem to do /summon giant. It said "unable to summon object"

The command is case sensitive, it has to be with a capital G.

This DID NOT WORK. I am on Minecraft 1.7.10 and I also tried it on 1.7.9, 1.7.6, and 1.7.2. It just said "There is no such item with ID mod." This happened on all of these. Help?

I think this page broke the awesomeness limit level. Kirsle you're a true genius, it's almost as if you designed the game itself!

-Bookmarked -Followed

Awesomeness level OVER NINE THOUSAND!!11!!!!1!!!ONE!

@Retarra:

How are you typing the commands in? That error doesn't make sense, unless you're typing something like, "/setblock ~ ~ ~ mod spawner .." or something.

The letters "mod" (with a D) should probably not even show up in the command at all, since they're mob spawners (with a B).

They can be obtained only by using the /give command, which gives a pig spawner by default; the mob can be changed by using a mob spawn egg on the block.

"It's a flaming pig in a cage, why is it spitting out chickens?" ~Anonymous


A mob spawner is a block that intermittently produces either monsters or animals when the lighting and surrounding conditions are appropriate. They are naturally found in dungeons.

Obtaining spawners

Spawners can be found naturally occurring in dungeons.

Mob spawners in the MinecraftOnline server can be collected by hand, unlike in the vanilla server (where they don't drop an item when broken). Simply break them with a diamond pickaxe as usual.

Breaking spawners placed by other players counts as griefing, in the same way as any other player-placed block.

Alternatively, as with just about every other block, it can be purchased at shops if they stock it.

Setting up spawners

Once it has been placed, a spawner needs to be set to a specific monster type, using /setspawner <mob type>. A spawner type can also be changed at any time after placement with the same command.

Spawner types

Allowable mob types are:

  • Chicken
  • Pig
  • Cow
  • Sheep
  • Zombie
  • Skeleton
  • Spider
  • Cavespider
  • Creeper
  • Slime
  • MushroomCow
  • Bat

The other mob types have been deemed too unfair to allow to be produced with spawners, as harvesting their drops would make certain challenging aspects of the game too easy.

Farming/Grinder Usage

This section is user added by -- bcMineOut and is NOT official guidance.

This information is not sanctioned or approved by the Admin team and is generated from user based understanding of best practices as of May 2019 for MC v1.7.10. This guidance is to be considered subject to change and ultimately the Admin team will act on spawners as they feel necessary, even if it's contrary to this guidance.

While no formal rules have been codified on this topic, there appears to be some general best practices that should keep your spawner/grinder from being deactivated.

  • No Zombie grinders (Zombies are considered buggy and a cause for lag).
  • No more than 50 mobs present in a grinder while operator is AFK.
  • Avoid running grinders AFK in general.
  • No more that 10-15 spawners in a farm/grinder.
  • General feeling among users is 4-5 spawners should be a safe optimal number but YMMV.
  • Try to avoid running grinders when there is a high number of players on the server.

The key point here is that all grinders should be built to prevent massive build-ups of mobs and not be designed around the player sitting AFK at them. If your farm/grinder is a lag risk it is likely to be disabled. Another idea would be adding a manual on/off switch so your grinder is off when you're not around as an extra safeguard.

But, that being said, grinders appear to be evaluated on a case by case basis and action on them is wholly at the discretion of the Admin team based on situational and other concerns they may have.

Players are welcome to ask an Admin to evaluate their spawner setup for any obvious concerns with the understanding that those concerns could change at a later date.

Additional note: Several staff were approached to provide guidance on this topic at the time of writing and they deferred as they were wary of setting up player expectations/commitments and other concerns as expressed above.

Trivia

  • It used to be necessary to ask admins to convert mob spawners they found in dungeons to an item, although this is no longer the case thanks to a drunken idea by  SlowRiot.
  • Previously mob spawners had to be configured using the /mspawn command by a moderator - this was a risky business, as there was a chance that a mistake could crash the server. This is no longer an issue since the creation of the /setspawner script.
  • Admins should take care not to confuse /setspawner with /setspawn - this is not the sort of mistake you want to make!
  • When broken, spawners often leave visible flames floating where they were. This can be fixed by relogging.
  • Spawners placed on grass produced invincible pigs before the 1.7 update, which were in fact client-side. Only you could see them, although most clients would produce their own invincible pigs when looking at the spawner, usually in different locations. They could be affected by you, but could move you around. It was one of Notch's little bugs caused by his deeply flawed philosophy of forking client code to make a server.
  • Zombie Pigmen (PigZombies) used to be permitted, as they dropped nothing. Now however they drop gold nuggets, making them a valuable resource.
  • Steves used to be able to be spawned, but Notch wrote them out of the game entirely. Villagers just aren't the same at all.

Forum thread

Configuration

usePermissions (false) - Whether to use Bukkit's superperms system, or the defaults below.

useWorldGuard (true) - Whether to use WorldGuard protection, if present.

minSilkTouchLevel (1) - Minimum enchantment level required for Silk Touch to harvest spawners. Normally Silk Touch I is required, but you can set this to 0 to make no enchantment required, or 2+ to require non-standard (normally unobtainable) enchantments.

destroyDropEgg (false) - Whether to give a spawn egg when spawner is destroyed without Silk Touch.

destroyDropXP (0) - Experience points to drop when spawner is destroyed.

destroyDropBars (0) - Iron bars to drop when spawner is destroyed.

ignoreFakeBreakEvents (true) - Ignore subclassed spawner block break events sent by other plugins (such as mcMMO with superbreaker).

denyBreakHoldingSpawner (true) - Deny players from breaking blocks while holding mob spawners, to prevent silk touch exploit.

consumeEgg (true) - Consume spawn eggs used to change spawners, or otherwise keep the egg in the player's inventory.

useReflection (true) - Use reflection to get/set mob IDs, or otherwise use Bukkit's wrapper. Required for custom mobs.

spawnEggOverride (false) - Override CraftBukkit's spawn egg routine and allow you to spawn any entity whatsoever by right-clicking the appropriate spawn eggs -- any entity is allowed, including enderdragons, ender crystals, primed TNT, boats, or even invalid entities, so be careful (note that SilkSpawners won't give you an egg for any item using /ss if it isn't in the config) -- although IDs can be disabled with the option below. Mainly intended for testing purposes, or if you want to spawn modded items not recognized by CraftBukkit.

spawnEggOverrideSpawnDefault (true) - If no enableSpawnEggOverrideAllowSpawn is given per-creature, use this instead.

enableCreatureDefault (true) - If no enable is given per-creature, use this instead.

verboseConfig (false) - Log verbose configuration information on load.

spawnerCommandReachDistance (6) - How close you have to be to use the /spawner command.

craftableSpawners (false) - Enable crafting mob spawners using spawner egg in center surrounded by 8 iron bars. Once enabled, crafting spawners for individual creatures can be disabled by setting enableCraftingSpawner to false in the creatures section below (if omitted, will default to true, but both config options must be enabled for spawners to be craftable).

useSpout (true) - Set to false to not use Spout features even if Spout plugin is present. If Spout is not detected, this option has no effect.

notifyOnClick (true) - Whether to notify a player the spawner type when clicking a spawner in inventory.

notifyOnHold (true) - Whether to notify a player the spawner type when holding a spawner.

spawnersUnstackable (false) - Prevent spawners from stacking, by setting max stack size to 1. Useful on CraftBukkit++ to prevent spawners from stacking when dropped as items. Not needed on vanilla CraftBukkit builds.

defaultCreature (null) - When generic spawner items are placed, spawn this creature (or null for Minecraft's default, pigs).

All spawner items obtained using SilkSpawners will have the creature type stored, but the default creature will be used if the spawner is obtained using:

  • /give player 52
  • 1.9 beta pre-release 6 silk touch
  • other plugins not knowledgeable of SilkSpawners' conventions

creatures - Mapping between internal mob ID string for spawners, and other crucial information. Keys include:

creatures.X.aliases: An optional list of aliases to recognize as alternate names for the mob.

creatures.X.displayName: The human-readable name of the mob.

creatures.X.enable (true): If false, this entity is skipped entirely and not recognized by SilkSpawners. Useful to exclude non-mob entities. If this key is missing, enableCreatureDefault will be checked instead. Note that entities not auto-detected are always skipped, so this key is safe to leave false for entities for mods you don't have installed.

creatures.X.enableCraftingSpawner (true): If craftableSpawners is enabled (see above), then a crafting recipe will be enabled for this mob unless this config option is false.

creatures.X.enableSpawnEggOverrideAllowSpawn (true): If spawnEggOverride is enabled, allow spawn eggs to be used for this creature. Set to false to block spawn eggs. If this key is missing, spawnEggOverrideSpawnDefault will be checked instead. Note that if spawnEggOverride is disabled, this option has no effect.

Permissions

Permission support is optional and off by default. When turned off, the settings shown in parentheses below are used, intended to allow for easy setup with minimal configuration.

For more advanced setup, set usePermissions: true in config.yml, and all permission nodes will be set to false, allowing for flexible configuration through your permission plugin as desired.

silkspawners.info (true) - Allows you to see informative messages about the spawners as you place and break them

silkspawners.silkdrop (true) - Allows you to use silk touch to acquire mob spawner items

silkspawners.destroydrop (true) - Allows you to destroy mob spawners to acquire mob spawn eggs / iron bars / XP (as configured)

silkspawners.viewtype (true) - Allows you to view the spawner type using /spawner

silkspawners.changetype (op) - Allows you to change the spawner type using /spawner [creature]

silkspawners.changetypewithegg (op) - Allows you to change the spawner type by left-clicking with a spawn egg

silkspawners.freeitem (op) - Allows you to get spawner items in your hand for free using /spawner [creature]

silkspawners.freeitemegg (op) - Allows you to get spawn eggs in your hand for free using /spawner [creature]egg

Technical Details

SilkSpawners stores the entity ID of creature in two places within the mob spawner item:

  • Durability (damage value), if possible. SilkSpawners does not rely on this field, although it will use it if it is available on newer builds which allow storing data on mob spawner items (see BUKKIT-329).

  • Enchantment SILK_TOUCH level

When a spawner block is broken, a spawner item drops with the appropriate entity ID stored, obtained from the creature spawner tile entity (CraftCreatureSpawner). When a spawner block is placed, the entity ID is read from the item and the spawner creature type is set (using the CreatureSpawner BlockState).

For plugin developers: if you want to interoperate with SilkSpawners' monster spawner items, use or on the , the enchantment level storing the creature type Entity ID.

Bukkit provides an EntityType wrapper, but it is implemented using an enum which cannot be easily extended by mods (without using reflection, as they do for the ItemStack wrapper), so SilkSpawners does not use this enum when possible, and instead directly accesses the net.minecraft.server classes if it can. If it fails or if useReflection is false, SilkSpawners will fallback to the EntityType wrapper.

Limitations

SilkSpawners only changes the spawner type, it does not manage the spawning itself; the spawning algorithm remains up to Minecraft. Other plugins offer more control.

If creaturebox is also installed, drops two spawners. Install either SilkSpawners or creaturebox, not both.

Not Enough Items may show all spawners as "Pig", because it does not recognize how SilkSpawners stores the spawner creature type (should be fixed after BUKKIT-329).

In the inventory window, item description is "Monster Spawner" for all kinds of spawners. Fixing this requires a client-side mod.
