Talk:Monster Room

I was just wondering where you guys got all the statistics and percentages, did you calculate them or something? TheFoxGirl (talk) 13:30, 15 May 2015 (UTC)

Pretty much; analyzing decompiled source code. -- Orthotope^talk 15:26, 15 May 2015 (UTC)

While I was playing in a test world in version 15w51b, I found a dungeon that generated over a ravine and had part of the floor missing. I reported it as a bug on the bug tracker. It is a bug because the floor of the dungeon was not entirely solid, yet the dungeon was still generated. It turns out, my bug, MC-94804 was a duplicate of MC-48442. One of the moderators' comments on my issue said: "The order how caves and dungeons are created is most probably wrong on the wiki." This is making me doubt that the conditions for dungeons to generate are outdated for the 1.9 snapshots, however they could be outdated for the current version which is 1.8.9, thus making it incorrect, but I have not tested it as of yet. BrenBanStudios (talk) 23:05, 25 December 2015 (UTC)

According to the tracker, MC-48442 was fixed in 14w20a, so definitely outdated. Fixed. -BDJP ^(t|c) 00:16, 26 December 2015 (UTC)

What's most likely happening here is that the dungeon in chunk 29,71 (that overlaps into 29,72) generates first, then the ravine from another adjacent chunk happens to cut through the floor. Anomie x (talk) 15:04, 26 December 2015 (UTC)

The algorithm on this page defines openings as "2-high air spaces". Do they need to be exactly 2 blocks high, or do they just need to be at least 2 blocks high? The Blobs^{👁 Image}

Who cares? Mojang doesn't intend for us to care about this stuff, they just expect us to find a dungeon, beat the mobs, disable the spawner, loot the chests, and scram, instead of dwelling on the generation algorithm that doesn't actually affect gameplay at all. 2607:FEA8:88C0:DC00:E78E:C5B0:AA64:9C13 23:22, 15 February 2025 (UTC)

It can be over 2 blocks high, it just has to be AT LEAST 2 blocks. But it cannot be over 7 blocks, because then it would go over the roof or under the floor. --BigBadE (talk) 01:48, 10 February 2020 (UTC)

The article states there are 8 attempts to generate a dungeon per chunk. But the default setting in the customized world type ist 7 and as far as I know these settings resemble the default world type. So is 8 really true? Fusseel (talk) 10:56, 4 July 2017 (UTC)

Alright, I found it myself, but it's still pretty weird. 8 is the default value in the code, so it's true. Surprisingly enough 8 is also the default value for customized although it shows 7 in the world options. Only manually adjusting the slider and switching it back to 7 actually changes the value. I hope that makes sense. Fusseel (talk) 11:08, 4 July 2017 (UTC)

Does this structure make any use of the cave_air block when searching for a place to generate? -PancakeIdentity (talk) 20:47, 24 July 2019 (UTC)

It sets blocks to CAVE_AIR, but doesn't check cave air, it only checks for gaps in general. --BigBadE (talk) 01:49, 10 February 2020 (UTC)

I dont understand why the verz. goldene Apfel have in englisch 3,1% but when i calculate its 1,5%

Back calculating of english list (% + % + % = 184,4%) Back calculating of german list (% + % + % = 99,6%)

Why this different ?

Teayo (talk) 21:26, 20 January 2020 (UTC)

I believe that the Golden Apple chance in English is the chance over every roll, while your calculation is just for one roll. --BigBadE (talk) 01:59, 10 February 2020 (UTC)

fYI I've put a nowiki around this as it was causing several entries in the WantedTemplates report. Feel free to correct to use English templates. - User-12316399 (talk) 13:20, 5 March 2020 (UTC)

I don't know why, but I've been finding a lot of dungeons around or attached to mineshafts while flying around in spectator in the latest version. Is it just me or is this anything?--Starfire2020 (talk) 23:01, 30 May 2021 (UTC)Starfire

Browsing seed -513070979 on Chunkbase shows 2 dungeons near the spawn point in Bedrock 1.16 but none in Bedrock 1.17.

The locations of other structures (monuments, buried treasure, shipwrecks, etc.) seems unchanged. Did something happen to the algorithm that generates dungeons? I don't see that mentioned in the change log. Amatulic (talk) 17:01, 20 June 2021 (UTC)

Square root of two thanks for updating the history to answer my question. Amatulic (talk) 23:32, 21 June 2021 (UTC)

The article previously stated dungeons generate above Y level 6, which is not accurate as I have seen many dungeons deeper down than this. I checked the decompiled code for 1.19.2 (minecraft/data/worldgen/placement/CavePlacements.java) and saw these values:

MONSTER_ROOM = PlacementUtils.register("monster_room", CaveFeatures.MONSTER_ROOM, CountPlacement.of(10), InSquarePlacement.spread(), HeightRangePlacement.uniform(VerticalAnchor.absolute(0), VerticalAnchor.top()), BiomeFilter.biome()); MONSTER_ROOM_DEEP = PlacementUtils.register("monster_room_deep", CaveFeatures.MONSTER_ROOM, CountPlacement.of(4), InSquarePlacement.spread(), HeightRangePlacement.uniform(VerticalAnchor.aboveBottom(6), VerticalAnchor.absolute(-1)), BiomeFilter.biome());

Two different ranges for generation (ten in 0 to top[320], four in -58(bottom+6) to -1), which I outlined in my edit. Hope this helps!

Why is the title monster rooms, but everyone calls them dungeons? Is this an update in 1.20 or what? --221.126.246.210 01:11, 29 November 2023 (UTC)

They were renamed to "monster rooms" in Java 1.14, and as they have no display name and are no longer referred to as "dungeons" by Mojang, the page was moved to the new name. BDJP ^(t|c) 01:14, 29 November 2023 (UTC)

Yeah, it's technically a monster room, but dungeon just sounds so much better. Like, who would want to be just walking through a cave and then say to their buddy, "Hey, there's a monster room over here!" It just sounds so stupid. "Hey, we got a dungeon over here," sounds so much better.

Everybody calls them dungeons, which makes so much more sense.

COME ON MOJANG! CHANGE IT BACK!!! 2607:FEA8:88C0:DC00:E78E:C5B0:AA64:9C13 23:18, 15 February 2025 (UTC)

Just so you know, Mojang doesn't read MCW talk pages. This is for discussion on how to improve the page. --MinecraftExp123^{(talk|contribs)} 02:54, 16 February 2025 (UTC)

haha, I know, I'm just being rhetorical. 2607:FEA8:88C0:DC00:4932:929D:4947:9F94 23:10, 26 February 2025 (UTC)

Like saying "I have a monster room here." is not the same as "Hey, I've got a dungeon here." and the monsters could have been locked in the dungeon for a reason. right? 👁 Image

According to my researches, name "Monster Room" never appeared in java translation files. The name "Dungeon" with translation key "createWorld.customize.custom.useDungeons" existed until 1.21.3 and translation key "createWorld.customize.custom.useDungeons" still exists in BE. Sorry if I'm wrong but where did yall find the name "Monster Room"? — 👁 Image

MetroKopUA (talk) 04:36, 20 February 2025 (UTC)

"Monster Room" is the in-game name in Java Edition. You can see it using the /place command. The full command is /place feature minecraft:monster_room. Rampage455 (talk) 05:09, 20 February 2025 (UTC)

Do you mean the actual name or just an identifier? SymORmaK (talk) 14:35, 20 February 2025 (UTC)

Well, Dungeon isn't an actual name either as it's never seen in-game. --MinecraftExp123^{(talk|contribs)} 05:51, 21 February 2025 (UTC)

There is a line like this in the translation files (or whatever you want to call them): createWorld.customize.custom.useDungeons=Dungeons SymORmaK (talk) 06:33, 21 February 2025 (UTC)

That never appears in game, but the /place command exists in-game, so monster room is visible to players. --MinecraftExp123^{(talk|contribs)} 06:37, 21 February 2025 (UTC)

Also please take a screenshot or give me a link where that is used. I'm pretty sure it's not in the source code. Also you already said it's no longer there as of 1.21.3. --MinecraftExp123^{(talk|contribs)} 06:42, 21 February 2025 (UTC)

First of all, I didn't say that, and secondly, I took this line from the Bedrock Edition files. SymORmaK (talk) 06:45, 21 February 2025 (UTC)

You did, as in "existed until 1.21.3". The wiki takes Java Edition names over Bedrock Edition names, but if that appears in-game, I guess that takes priority. Can you show me a screenshot of that in-game? --MinecraftExp123^{(talk|contribs)} 06:47, 21 February 2025 (UTC)

It was Mr. MetroKopUA who said that, not me. As for the screenshot, I'm not sure if it's in the game at all, maybe in the developer releases, but not in the regular game. SymORmaK (talk) 06:50, 21 February 2025 (UTC)

Oh, never mind. But still, I think something visible in-game has priority over something only in the code. --MinecraftExp123^{(talk|contribs)} 06:51, 21 February 2025 (UTC)

I thought that since Bedrock has a name for this, but Java does not, the Bedrock version should be used 🥲 SymORmaK (talk) 09:12, 21 February 2025 (UTC)

But the word "dungeon" actually doesn't exist within the game, but in Java Edition montser_room is used in-game, with commands. --MinecraftExp123^{(talk|contribs)} 12:21, 21 February 2025 (UTC)

I guess I agree with you, well, let's keep existing name then. SymORmaK (talk) 16:07, 21 February 2025 (UTC)

Nah, I hate it, Mojang needs to change this 2607:FEA8:88C0:DC00:4932:929D:4947:9F94 23:11, 26 February 2025 (UTC)

You can suggest moving this page. Arina (she/her) 08:07, 14 March 2025 (UTC)

When did dungeon change to monster room, or was it never dungeon? The history section says it was monster room on addition, but the lead says it changed in 1.13. Which is correct?  Nixinova  T ⁄ C  22:11, 8 November 2025 (UTC)

I don't think these were ever properly renamed from "dungeon" to "monster room", but we can assume they have always been "monster rooms" in code and but also occasionally referred to as "dungeons" officially. "Dungeon" itself seems to originate as a community-made name.

• In Beta 1.2_02 (20110517), which is unobfuscated, they are called "monster rooms" in code (MonsterRoomFeature), and it's safe to assume this is the same name Notch had used since Infdev 625 as none of the other class names were renamed to match updated names (e.g. ClothTile, HellSandTile etc). There is a class named DungeonFeature, but it seems it's a copy of LargeCaveFeature and it's unused.
• In Beta 1.8, the generate structures option was added, and its description mentions "dungeons" (despite it not working on monster rooms/dungeons, so it's possible it was meant to generically refer to strongholds or mineshafts which were added in the same update). It's worth noting that the Beta 1.8 changelog on MCUpdate describes strongholds as "huge underground dungeons".
• 1.4 added customized superflats, and monster rooms are referred to as dungeon in the preset code syntax.
• 1.8 added custom world settings, and here monster rooms were clearly and unambiguously called "Dungeons".
• 1.9 added loot tables, and the loot table for monster rooms is simple_dungeon.
• 1.14.4, which is the earliest version with Mojang mappings, uses "monster room" in code (MonsterRoomFeature).

Currently "dungeon" or "monster room" are never mentioned in any displayed string in Java nor in Bedrock (customized world settings were removed and the generate structures description has been changed to mention shipwrecks instead). --Capopanzo (talk | contribs) 01:34, 9 November 2025 (UTC)
