Initial Technical Details[edit]

Decompiling the 14w25a code (bdi.class) reveals that internally, this structure is referred to as a "Monument". It can only spawn in a chunk whose coordinates satisfy an equation (similar to Villages) and which has the biome Deep Ocean at its center point (+8,8 from the chunk corner). It also requires an aquatic biome (regular/Deep/Frozen Ocean, regular/Frozen River) everywhere within a 29 block square radius around the center point (i.e. a 59x59 square, not a circle).

Capitalization of all these new 1.8 blocks and things[edit]

I take this question here specifically, because by now this is a well-edited page. Pardon me if I was supposed to put this kind of thing somewhere else.

I have been wondering about the capitalization standards. Reading through the style guide, I got the idea that the new blocks and items ought to be referred to in the lowercase, as 'prismarine shards', 'prismarine', 'prismarine blocks', 'dark prismarine', 'prismarine crystals', 'sea lantern', 'sponge' and 'wet sponge' -- except when in the title or at the beginning of a sentence, then it's sentence case. Would that be right? I know 'prismarine' is an invented term, but style guide indicates only capitalizing invented species, so I am stuck on that.

Furthermore should 'ocean monument' be all lowercase? I know it has a biome name in it, but does that matter?

And since 'Guardian' and 'Elder Guardian' are invented species (unlike 'bat' or 'pig'), they are supposed to be capitalized, correct?

Oops, that was me: – Sealbudsman (Aaron) (talk) – 18:45, 20 June 2014 (UTC)

I dunno who wrote this (I do " 18:35, 20 June 2014 (UTC), er ~ ~ ~ ~ minus-spaces " after a Post /Comment, and am-subject to being "Edited" into Oblivion, like "anyone), but I do more than capitalize for Emphasis. My short-hand rule of Gaming thumb is that if a Game has a specific-term, which within that -particular Game's context(s) has a specifically-different meaning, than R L, then it gets-capitalized.

This even means I'll Re-capitalize things, after-already Ref'd. This is because often assumptions people make about R L /(a) Game(s) inter-bleed until they really Can't understand a given, particular set of Game (singular) Mechanics. Yilante 18:35, 20 June 2014 (UTC)

Capitalizing makes no sense, guardian is not a proper noun, so there is no reason to capitalize it. Moreover, there are a lot of guardians, a lot of endermites, a lot of ocelots. If you want to somehow highlight the fact it's an invented species, you can italicize it. IllidanS4 (talkcontribslogs) 10:32, 21 June 2014 (UTC)
I wasn't really saying that I was looking for alternatives to the style guide.. I fully intend on writing in conformity with the style guide.. I was just trying to figure whether or why the stuff already written about the ocean stuff was or wasn't in conformity to it. But it looks anyway like someone went ahead and fixed the majority of it. – Sealbudsman (Aaron) (talk) – 16:43, 21 June 2014 (UTC)

It is Capitalized[edit]

I was trying out the new customized world settings in the latest snapshot and saw that ocean monuments were referred to as Ocean Monuments, not Ocean monuments. TheFleet123 (talk) 19:49, 5 August 2014 (UTC)

Room generation[edit]

I was bored enough to dig through the obfuscated code and determine how exactly the maze of rooms in a monument are generated.

  1. It starts with 49 small rooms: two layers of 20 (5×4) with one layer of 6 (3×2) on top, plus 3 dummy rooms representing the wings and the "penthouse" at the top. Every room connects to all adjacent rooms (up, down, left, right, forward, and back, including connections with the dummy rooms), and all the walls between connected rooms are initially marked as "open". The 46 non-dummy rooms are marked as "unused", while the dummy rooms are "used".
  2. The Core (taking 2×2×2 of the small rooms) is placed somewhere at the back of the monument. The 8 small rooms taken up by the Core are marked as "used".
    • If the Core is at the far left or far right, it will open into the passage connecting the two wings.
  3. The list of small rooms is randomized, and for each room up to 5 attempts are made to close walls until two closures succeed:
    • A direction is chosen: up, down, left, right, forward, or back.
    • If the wall in that direction is already closed, the attempt fails.
    • The wall is marked as closed.
    • The two rooms on either side of the wall are checked to make sure a path through open walls still exists from each one back to the entry room. If either fails, the wall is re-opened and the attempt fails.
  4. Place the 1×1×1 entry room, marking that small room as used.
  5. The randomized list of rooms is gone through again to choose what size monument room will be placed for each one that is still unused. The first option that fits is applied:
    1. If the walls between the current room, the one above, the one to the right, and the one above and to the right are all open and all those rooms are still unused, place a 2×1×2 room (marking the 4 as used).
      • This room has two hollow pillars coming up with openings in each facing the top-center, and four sea lanterns at corners beneath the openings.
    2. If the walls between the current room, the one above, the one to the back, and the one above and to the back are all open and all those rooms are still unused, place a 2×1×2 room (marking the 4 as used).
      • This is a largely open room with a 2×2 pillar made of dark prismarine and sea lanterns in the middle. Openings in the top of the left and right walls have a ledge with a frame around the potential lower openings.
    3. If the wall between the current room and the one behind is open and the one behind is still unused, place a 2×1×1 room (marking both as used).
      • This room has an open-centered structure made of prismarine bricks in the middle, with sea lanterns on the four corners.
    4. If the wall between the current room and the one to the right is open and the one to the right is still unused, place a 2×1×1 room (marking both as used).
      • This room is U-shaped: one wall has an outcropping consisting of a 6×4 rectangle of prismarine bricks on the floor and ceiling with a 4×3 rectangle of prismarine with sea lanterns at the corners in the middle.
    5. If the wall between the current room and the one above is open and the one above is still unused, place a 1×1×2 room (marking both as used).
      • This tall room has 2×2 corners of prismarine bricks midway up, each with the piece in the corner of the room missing. Open walls have insets in the side such that two of these rooms adjacent will have additional 2×1 openings on either side of the usual passageway.
    6. If all walls except the bottom are closed, place a 1×1×1 sponge room.
      • Each of the 36 columns in the room has a 13 chance of being empty, a 12 chance of having one sponge, and a 16 chance of having two sponges. The walls have dark prismarine.
    7. Otherwise, place a 1×1×1 non-sponge room.
      • (13 chance) A small room made plus-shaped by 2×2 prismarine bricks at floor and ceiling in each corner, with sea lanterns in the four corners at the middle level.
      • (13 chance) A small room with four 1×1 pillars of prismarine brick and sea lantern. If both the top and bottom walls are closed and at least two other walls are open, has a 50% chance of having a 2×2 pillar in the middle.
      • (13 chance) A small, normally empty room with dark prismarine on the walls. If both the top and bottom walls are closed and at least two other walls are open, has a 50% chance of having a 2×2 pillar made of prismarine and prismarine bricks in the middle.

If anyone finds this interesting enough, feel free to incorporate it into the article. Anomie x (talk) 06:37, 26 October 2014 (UTC)

Where on the ocean?[edit]

This may be a very silly question, but do these structures generate on the ocean floor or underneath it? I assume it's the first, but the article doesn't say. The reason I ask here and not on some forum is because I think this ought to be mentioned, maybe just in the first paragraph. I cannot be the only one who is trying to find one without a map! 22:30, 8 January 2017 (UTC)

Drowning Prevention Tips?[edit]

Since this Wiki is primarily aimed at newcomers to Minecraft, it might be helpful to add something about ways to stay underwater in order to facilitate exploration of these ocean monuments. Things like relevant enchantments, temporal limitations, etc. Since the monuments manifest at the bottom of deep oceans, I thought it might be useful to add information such as this to help people without a lot of experience avoid drowning. If I am just missing something, I apologize, but I myself am a newcomer to Minecraft, and trying to learn as much as I can via this outstanding Wiki. Thank you. 18:34, 1 April 2017 (UTC)

Such things can be found over here; in this case, see Tutorials/Defeating an ocean monument. - MinecraftPhotos4U (talk) 19:33, 1 April 2017 (UTC)
Which I'm sure could use - itself - an update since 1.13 (Aquatic Update), between Swimming-between previously-inaccessible holes to block "laser beams" of Guardians every few sec's. and Always having extra diving-Helmets, available. Also the trick of items-"floating upwards," since (instead of drifting /sinking downwards), and becoming-invisible "in the ceiling," of all-but Transparent, Blocks, if-Blocked.

Like Coral Reef? (Generated Structure of 1.13 Aquatic Update)[edit]

So there are several reef-like features of the longer-extant O M. Basically All of them, if you look closely.

Should I List them, even? I'll just note they All, are (there, and ".. that's no reef!" is kind of valid, here). Yilante 8 /29 /18 5:43 a.m. 12:43, 29 August 2018 (UTC)

Odd Generation[edit]

Hello, should we add any photos in the gallery for odd generation? Because I think I've come across some in my world that is worth noting. From the images I have taken (they are not uploaded right now), it looks as if the moment the Monument hit something other than a deep version of an ocean, it stopped generating. Should this be considered? Resmartian01 (talk) 16:50, 28 June 2019 (UTC)

Done. Resmartian01 (talk) 17:37, 20 July 2019 (UTC) Resmartian01 (talk) 17:37, 20 July 2019 (UTC)

@Resmartian01:: It isn't odd, it's just an artifact of a structure generation that overlaps a pre-existing chunk. I left an expanded explanation on File talk:Ocean monument odd generation.png. ~ Amatulic (talk) 17:09, 19 September 2020 (UTC)
