El interfaz de intercambio mostrando un intercambio de 28 unidades de papel por 1 esmeralda.

El sistema de intercambio es una mecánica del juego que permite al jugador intercambiar esmeraldas por objetos y viceversa con NPC aldeanos.

Funcionalidad

Usando click derecho sobre un aldeano abrirá un interfaz que permitirá al jugador intercambiar con él. Los aldeanos harán ofertas basadas en su profesión, y solamente harán intercambios basados en las ofertas que ellos mismos hacen. Se pueden observar ofertas distintas si se va pulsando los botones de derecha e izquierda que se sitúan al lado de la oferta mostrada. Todas las ofertas incluyen esmeraldas como recurso, y algún objeto perteneciente a la profesión del aldeano. El intercambio permite la adquisición de objetos poco comunes que si fuera de otro modo sería realmente difícil de obtener, como la armadura de malla. También es e único modo de obtener los frascos con experiencia en el modo supervivencia.

Un aldeano nunca ofrecerá para comprar/vender el mismo objeto a diferentes precios o cantidades (por ejemplo, un mismo aldeano no ofrecerá chuletas de cerdo crudas a por 16 esmeraldas y 17 esmeraldas a la vez, sólo puede haber una oferta para comprarlas). Sin embargo, las cantidades y precios pueden variar entre aldeanos, y las cantidades/precios pueden variar cuando se generan nuevas ofertas.

Todos los aldeanos tienen en un inicio solamente una oferta. Pueden generar nuevas ofertas cuando la última oferta se ha cumplido al menos una vez. Es importante que se cierre el interfaz de intercambio antes de que el aldeano genere una nueva oferta. Al hacerlo, los aldeanos se ven envueltos con partículas verdes y moradas por un momento. Las nuevas ofertas pueden involucrar objetos que un aldeano ya estaba ofreciendo para comprar/vender: es cuyo caso, la oferta que se genera posteriormente sobrescribirá la anterior, permitiendo que los precios del aldeanos varíen. Pese a eso no hay un límite del número de ofertas que un aldeano individual puede hacer, solamente pueden tener una oferta por cada tipo de objeto que puedan intercambiar. Además, cuando un aldeano ya tiene varias ofertas, hay una alta probabilidad de que una oferta recién generada sea sobre un objeto que ya se ha ofrecido: pese a que la oferta antigua se sobrescriba, y no haya ningún espacio de oferta nuevo que se añada al aldeano.

Los aldeanos desactivarán una oferta si se ha usado un número determinado de veces y no es la única disponible. La probabilidad de que una oferta se desactive es aleatoria, pero una oferta se debe cumplir al menos 3 veces antes de que pueda ser desactivada. Después de que una oferta se haya usado 13 veces, se desactivará en todo caso si se cierra el interfaz de intercambio después de cumplirla. Intercambiar la última oferta activará una nueva oferta.

Antes de la Pretty Scary Update (v1.4), era posible intercambiar más de 13 veces sobre una misma oferta porque las ofertas no se eliminaban hasta que se cerraba el interfaz. Esto significaba que podías cumplir una oferta tantas veces como tus espacios en el inventario te lo permitieran. Actualmente, los aldeanos pueden interrumpir un intercambio de un objeto en particular si las condiciones para la desactivación se han dado incluso si el interfaz sigue abierto. Esto puede causar comportamientos extraños en el inventario cuando el jugador usa shift+click durante el intercambio. Al principio parece que el inventario se ha completado, pero después los objetos vuelven a estar igual que antes. Cuando se cierra y reabre la ventana del intercambio, la oferta se mostrará, pero X rojas indicarán que ya no se encuentra disponible. Pese a eso, solamente se puede eliminar na oferta después de que se cierre el interfaz de intercambio: si intercambias ofertas múltiples antes dentro límite, solamente se eliminará el último intercambio. De este modo, una oferta con más de 13 usos se pueden mantener y el juego no comprueba las ofertas para desactivar hasta que la oferta se completa.

Además, si una oferta es la última que está disponible, nunca se desactiva cuando sus usos exceden 12. Puesto que ya no es la última oferta, puede que se elija para que se desactive. Cuando una oferta se desactiva, tiene el mismo efecto de partículas que cuando se crea una oferta.

Desafortunadamente, no se puede cambiar lo que un aldeano vende, por lo que habrá que intercambiar hasta que todos los objetos se desbloqueen.

Posibles ofertas

La siguiente tabla lista el mínimo y máximo de ofertas que un aldeano hará cuando se compren y venda objetos.

Granjero

Librarian

Priest

Blacksmith

Butcher

Generic Villager (green clothes)

Note: The green villager is only obtainable using /summon, server commands, mods, or third-party map editors on version 1.7.6 or lower. In the first 1.8 snapshots when the new villager professions were added, its number was changed to -1. It doesn't spawn naturally, even when using a spawn egg.

Notes

1. ↑ ^{1,0 1,1 1,2 1,3 1,4 1,5} Gold ingot offers do not have a probability value in the code, except for one of the two blacksmith offers. If no potential offers are generated, then the game will default to an offer of gold ingots. Note that this offer is more likely when all other offers have a low probability.
2. ↑ The enchantment is chosen randomly, with equal chance of any enchantment type occurring and equal chance to get any level of it, so higher-leveled enchantments are as likely to get as low-leveled enchantments. The price in emeralds depends on enchantment level only. The possible values are 5 – 19 emeralds for Lvl I, 8 – 32 for Lvl II, 11 – 45 for Lvl III, 14 – 58 for Lvl IV and 17 – 71 for Lvl V.
3. ↑ Priests will offer to enchant items for you. Every enchantment costs between 2 – 4 emeralds, and requests the item to be enchanted in the first slot. Trading for an enchanted item in this manner repairs the item if it is damaged, allowing items to have infinite durability at the cost of emeralds. When creating the enchantment offer, the game uses a random enchantment level from 5 – 19. For a listing of what enchantments will show up at these levels, see Enchantment Mechanics
4. ↑ ^{4,0 4,1} Villagers buy Charcoal as Coal in 1.7 versions, but not since snapshot 14w02a (1.8)
5. ↑ The blacksmith actually has two chances to offer to buy gold ingots. This is because it is an explicit offer a smith may ordinarily make (0.5 probability value, or 6.6765% chance), and it is also a default offer for all villagers (with a 0.0052% chance from a blacksmith). Note that, despite two chances to generate a gold ingot offer each time an offer is generated, a blacksmith will never have two separate offers to buy gold ingots in the trading interface, because the offers involve the same items.
6. ↑ "Price per Unit Ingredient" is the equivalent price per diamond gem or iron ingot that you would be paying if you were buying the diamonds or iron and then crafting the resulting tool or armor yourself. In the case of chainmail armor, these numbers are given for a theoretical comparison only, since chainmail cannot be player-crafted. In the case of tools, sticks used in the crafting of tools are ignored in the calculation.

Future

In 14w02a, Villager trading has been revamped:

• Villagers now spawn with careers.
  • Trades are now specific to career, and are unlocked in tiers
  • Villager career is now displayed in trade GUI.
• Buying/selling any of the available options can unlock new tiers/reactivate available options. This is opposed to having to trade the last offer.
  • An offer is guaranteed to reactivate available options (and unlock a tier, if some have not yet been unlocked) the first time it is traded. On subsequent attempts, it will only have a 20% chance of doing so.
• New offers will no longer rewrite old ones. New offers are appended to the end of the villager's list.
• Each tier consists of a defined set of trade offers, and the tiers are the same for any given career (see chart).
• When a trade has deactivated, the red X will appear immediately and prevent further trading, instead of having to close and reopen the trading window.
• Villagers now distinguish between damage values; so, different colors of wool CANNOT replace white wool, charcoal cannot be traded in place of coal, and damaged tools cannot be traded in place of fully repaired tools. NBT data, however, is still ignored, so the content of a written book does not matter.
• Trading now gives experience.
• All villagers in your world before 14w02a+ will retain their previous trade offers, but will gain the new trading mechanics.

Different careers are assigned to each Villager (viewable in the trading GUI). For example, brown-robed Villagers can be Fletchers or Fishermen; Blacksmiths can be Armorers or Weapon Smiths; etc. Every Villager spawns with Tier 1 of their given career, which range from 2-4 initial unlocked trades (i.e. all Shepherds will spawn with only two options, buying wool and selling shears).

Completing any trade offer with a Villager may unlock a subsequent tier of new offers and reactivate old ones. This is guaranteed the first time you trade a particular offer, and also has a 20% chance of occurring with subsequent trades to that offer.

The full list of careers and tiers is listed below:

Aldeano con túnica marrón (agricultor)

White Robed Villager (Librarian)

Purple Robed Villager (Priest)

Black Apron Villager (Blacksmith)

White Apron Villager (Butcher)

The green Villager is no longer obtainable, even using /summon, server commands, mods, or third-party map editors. Attempting to create one instead yields a Farmer.

The order of trades, including the order that they are unlocked, is the same for any given career of Villager. However, the prices and enchantments may vary between two Villagers of the same career.

1. ↑ ^{1,0 1,1 1,2 1,3 1,4 1,5 1,6 1,7 1,8} When creating an enchantment offer, the game uses a random enchantment level from 5 – 19. For a listing of what enchantments will show up at these levels, see Enchantment Mechanics
2. ↑ ^{2,0 2,1 2,2} The enchantment is chosen randomly, with equal chance of any enchantment type occurring and equal chance to get any level of it, so higher-leveled enchantments are as likely to get as low-leveled enchantments. The price in emeralds depends on enchantment level only. The possible values are 5 – 19 emeralds for Lvl I, 8 – 32 for Lvl II, 11 – 45 for Lvl III, 14 – 58 for Lvl IV, and 17 – 71 for Lvl V. Note that the cost is capped to 64, meaning that Lvl V books truly range from 17 - 64 emeralds, but costs at the upper end of the range are more common.
3. ↑ ^{3,0 3,1} Librarians offer the enchanted book trade three different times.

History

Issues

Issues relating to "Trading", "Trades", or "Trade" are maintained on the issue tracker. Report issues there.

Trivia

• Right-clicking on a villager pauses that villager's pathfinding.
• Right-clicking on a villager right after a killing blow is dealt will result in the player trading with a dead villager. The trade goes through without any problems.
• You cannot trade with child villagers.
• If you're not satisfied with the current trade offers, you can kill some of the villagers. The remaining villagers will start breeding again, resulting in possibly better offers. You can do this using environmental damage (fire, lava, TNT etc.) as not to aggravate the village's Iron Golem.
• Gold armor is the only armor that cannot be traded for. (Butchers sell leather, and the blacksmith every other type.)
• In the first Pre-release of the Beta 1.9 lost update, villagers had a "name bar" above their head similar to other players in multiplayer. Their name was "TESTIFICATE".

Prior to trading revamp

• Charcoal can be sold as coal to blacksmiths and butchers.
• Trading is currently the only legitimate way to get Bottles O' Enchanting without creative mode.
• Gold Ingots are used as a fallback offer; any time a villager randomly selects none of its offers, it chooses to buy gold ingots instead. This is why gold is offered so rarely as a trade, and also why it is the green villager's only item.
• It is possible, when trading for an Enchanted Book with a librarian, that the cost in emeralds exceeds 64. This only happens with books containing tier 5 enchantments.
