Fortalezas são estruturas geradas naturalmente abaixo da superfície, e são importantes por abrigar o portal do fim. Fortalezas podem ser encontradas usando o olho do fim.

Geração

Esse artigo fala sobre a geração da estrutura. Para localizar fortalezas, veja Olho do End § Encontrando Fortalezas.

O quarto do Portal do Fim.

Layout da fortaleza através do mundo em Java Edition.

Há um limite de 128 fortalezas por mundo. Todas as fortalezas estão localizadas em posições aleatórias dentro de anéis, cada anel com um certo raio da origem - o ponto em x = 0, z = 0, não o spawn do mundo, que pode estar a algumas centenas de blocos de distância. As fortalezas também podem se estender ainda mais dentro ou fora dessa área. O jogo não irá gerar uma fortaleza acima do solo: qualquer porção acima da camada do solo será substituída por blocos de ar, deixando um corte. As fortalezas podem gerar no nível da Rocha Matriz, cortando-a.

Na Edição Bedrock, 3 fortalezas geram dentro de um anel de raio entre 640 e 1152 blocos. Outras fortalezas serão geradas aleatoriamente em todo o mundo.

Na Edição Java, elas geram em anéis com as fortalezas uniformemente espaçadas ao redor do círculo até que o total de 128 seja atingido.

• O primeiro anel tem 3 fortalezas entre 1408 e 2688 da origem
• O segundo anel tem 6 fortalezas entre 4480-5760 da origem
• O terceiro anel tem 10 fortalezas entre 7552–8832 da origem
• O quarto anel tem 15 fortalezas entre 10624–11904 da origem
• O quinto anel tem 21 fortalezas entre 13696–14976 da origem
• O sexto anel tem 28 fortalezas entre 16768-18048 da origem
• O sétimo anel tem 36 fortalezas entre 19840–21120 da origem
• O oitavo anel tem 9 fortalezas entre 22912–24192 da origem

Na Edição de Console Legado, apenas uma fortaleza é gerada (mais que 3 em mundo superplanos).

Strongholds primarily generate underground, and prefer to generate in biomes above sea level but will generate underwater if necessary. Whole rooms can be flooded if the stronghold is intersected by a mineshaft or ravine. Sometimes, floating portal rooms can be found in the ocean, where no other room can generate. Na Edição Bedrock they also attempt to generate under village wells or meeting points. Most parts of the stronghold can be overwritten by ravines, caves, abandoned mineshafts or dungeons; but it is very rare that the end portal is replaced, which would force a player to find one of the other strongholds.

Structure

Strongholds vary in size. They contain several doors and rooms made mostly of stone brick (45%), mossy stone brick (30%), cracked stone brick (20%) and infested stone bricks (5%). Interestingly, infested cracked stone bricks and infested mossy stone bricks do not generate. Strongholds are lit by enough torches to provide visibility in most areas, though not enough to suppress mob spawns.

Each Stronghold contains several dispersed chests containing a variety of loot.

Rooms

Strongholds feature various types of main rooms. Each room has an entrance, which is either a plain 3×3 opening, a wall with a wooden door, a wall with an iron door (with buttons‌^{[EJ & ELC apenas]}), or a 3×3 opening with a grate of iron bars leaving a 1×2 opening, and may have exits to other room pieces or dead-end "exits" into stone. Additional "passages" between rooms may exist if their generation overlaps or if the stronghold intersects a cave, mineshaft, or other structure. Sometimes, doors can be sealed off by stone bricks, resulting in "secret doors", its usually occur on 5-way crossing.

Stronghold generation begins with a spiral staircase room with a 5-way crossing at the bottom, with additional rooms being randomly generated from the exits of previous rooms up to a maximum distance of 50 rooms and 112 blocks horizontally. If a portal room is not generated, generation is redone.

• End portal room: Contains an End portal and a silverfish spawner. There are two pools of lava in the front sides of the room and a bigger lava pool below the End Portal. There are 16 iron bars windows in the room, and the entrance is always a gate. One per stronghold, and never within 5 rooms of the starting staircase. On average, 0-3 eye of ender generate in the portal frames, and very, very rarely generates completely filled. Each portal frame has a 10% chance to be prefilled with an Eye, thus the chance of the portal being completely filled is one in a trillion (10^-12).
• Libraries (see below). Maximum two per stronghold, and never within 4 rooms of the starting staircase.
• Large rooms: A room with three exits (four counting the entrance). The center of the room may have various decorations. Maximum six per stronghold.
  • Empty rooms: Has no decoration.
  • Stone Pillar rooms: Has a stone brick pillar with torches on it.
  • Fountain rooms: Contain a fountain in the center, which consists of a stone brick ring and pillar with a water source block on top of the pillar.
  • Store rooms: Dual-level rooms, each 2 blocks high, with a cobblestone center structure joining the two. A lone torch is housed within the structure. A ladder runs up the side wall for access to the second floor, which is a chamber made of wood planks and containing a chest.
• Five-way crossing: Has up to five exits (six counting the entrance): one across from the entrance down a short stairway made of stone slabs and stone brick blocks, one each to the left and right of the entrance, one on the left side of the upper level reached by a short stairway made of stone slabs and stone brick blocks, and one on the right side of the upper level across a bridge of stone slabs and double stone slabs over the downward stair. A single torch is on the side of the bridge.

Na Edição Bedrock the 4 entrance of side, (both right and left and upper side) usually has 1 to 4 entrance sealed. Maximum five per stronghold.

• Empty prison cells: A corridor with one wall partially made of iron bars and with two iron doors (in an "open" position, with no buttons). Beyond each iron door are cells with an iron bar wall between them. An exit is opposite the entrance. Maximum five per stronghold. In Bedrock Edition, no iron doors will be generated.
• Spiral staircase: A 3×3 spiral stair made of stone brick blocks and stone slabs, leading down, with an exit at the bottom. Maximum six per stronghold.
• Straight staircase: A 3 block wide staircase of cobblestone stairs leading downwards, with an exit at the bottom of the stairs. There is also an empty alcove under the stairs. Maximum five per stronghold.
• Corridor: A bare corridor with up to 3 exits: one straight ahead, and optional exits to the left and right.
• Chest corridor: A corridor with a small altar made of stone brick slabs, with a chest on the altar. One exit, opposite the entrance. Maximum four per stronghold.
• Corridor turn: A bare corridor with one exit, left or right. May resemble a small room if both the entrance and the next room's entrance have doors.
• Dead-end corridor: A bare corridor with no exits, although it is likely to intersect other rooms. This room type never has a door or grate at the entrance.

Libraries

A library inside a stronghold.

Libraries occur in two sizes: Small single-level libraries, and larger duplex libraries. All libraries contain bookshelves, wood planks, chests and cobwebs dispersed randomly.

Large libraries contain a second level consisting of a surrounding balcony with fences as railings, and fences/torches arranged in a chandelier formation over the center of the room. The two levels are connected by ladders on the wall furthest from the entrance.

Chests are found on the corner of one bookshelf in each library, with an additional chest in the corner of the top floor in duplex libraries.

Problemas relacionados com "Fortaleza" são mantidos no rastreador de erros. Reporte problemas lá, em inglês.

Trivia

• There are exactly 233 bookshelves in one large Library Room, which, if mined without Silk Touch, will yield exactly 699 books.
• Though Strongholds do not generate above ground, they can be exposed through above ground dungeons or ravines.
• They can also sometimes be exposed underwater if they generate in terrain that is close to an Ocean.
• Strongholds have an increased chance of intersecting with other generated underground structures (dungeons, abandoned mineshafts, etc.) on the Legacy Console Editions of Minecraft, primarily due to generated worlds being much smaller than ones on Java or Bedrock Edition.
• The only variant of infested block that can naturally generate within strongholds are regular stone bricks. Interestingly, mossy and cracked variants cannot generate as infested blocks naturally.
• Mining an infested block with a Silk Touch pickaxe will not release silverfish, but instead will yield a normal block that can be used for construction.
• On Bedrock Edition, letting a silverfish enter any stone brick variants will turn these blocks into infested stone instead of the corresponding infested block. This can also happen on igloos with basement.
  • Because of this, infested stone can also be found outside mountains biome in this version.
