Um Ejetor é um bloco especial ligado por redstone. Quando clicado, um menu permite que você coloque os itens dentro dele. Cada vez que o bloco recebe energia a partir de um circuito de redstone, um item aleatório de seu estoque dropa fora. Ejetores assemelham-se com fornalhas e liberadores, mas os três blocos têm diferentes usos e receitas de criação.

Ejetando[editar | editar código-fonte]

A ação exata do ejetor depende dos itens que estiverem nele.

  • A maioria simplesmente será ejetada como itens cerca de 3 blocos a frente (se estiver no solo), similar aos itens largados pelo jogador.
  • Heads e Pumpkins serão colocadas (a partir da 14w04a).
  • Command Blocks will be placed with their Tile Entity data (a partir da 14w07a).
  • Arrows, Fire Charges, Chicken Eggs, Snowballs, Splash Potions, Bottles o' Enchanting, e Firework Rockets serão lançandos fora como quando o jogador aperta o botão direito do mouse.
    • Arrows fired from a height of 2 above level ground will go anywhere from 10 to 21 blocks away. When firing arrows, its optimal range for mob killing (if placed at eye level) is 1 to 5 blocks with a hit ratio of about 98% at the edge of the 5 block range on a target the size of a standard mob. Flechas causarão 3HP (1.5 corações) de dano, e podem ser picked up, unlike those fired by skeletons.
      • Arrows fired from a dispenser at the top layer not facing up or down will travel a maximum of approximately 80 blocks (±7 blocks) away from the dispenser before hitting the ground on the bottom layer.
      • Arrows fired from a height of 1 block above level ground, can go anywhere from 6 to 13 blocks away. In some weird cases, the arrows, 9 blocks away from the dispenser can go to the left or to the right of a target.
    • Chicken eggs and snowballs break with most of the usual effects. Any projectiles shot by the dispenser do not knockback the mobs that it hits; it is unclear whether this is a bug or not.
  • Fire Charges will become fireballs of the same type as Blaze fireballs and will continue in a straight line (though the line may be at an angle from the dispenser). Upon being dispensed, the fire charge will make the same sound as Blazes and Ghasts when they launch their projectile. However if used by the player, it makes the same sound as Flint and Steel.
  • Spawn Eggs will result in the corresponding mob being created with its feet in the block directly in front of the dispenser, with no initial velocity.
  • Minecarts and Boats will be placed (as their entity form), but only if the dispenser is placed above water (for boats) or on a rail (for minecarts).
  • Water and lava buckets will place water and lava source blocks. Water and lava source blocks will also be taken if there is an empty bucket inside. Water won't be placed if the dispenser is in Nether though.
  • TNT will be placed and ignited with no obvious forward velocity. However, when they are dispensed, they may be moving at a very small rate in a random direction before falling straight down. Thus, if you try to drop TNT using a dispenser above a one block by one block hole, the TNT will have a good chance of narrowly missing the hole. Because of this, extra caution must be used in delicate machines requiring TNT and dispensers.
  • Flint and Steel will ignite fire in front of the dispenser consuming one durability.
  • Bone Meal será usada on the crops it is pointing at.
  • Armor será equipada em um jogador que esteja a um bloco de distância.

All items which are fired out have a random variation in direction.

When a dispenser dispenses an item, it emits a clicking sound (unless the item is a projectile or a Spawn Egg) and a puff of smoke. If it is empty when activated, it emits a slightly higher-pitched click.

Triggering[editar | editar código-fonte]

Unlike most other redstone devices, it may be triggered by redstone wire placed up to one block adjacent to it, as well as running directly into it; therefore, a single redstone wire can trigger up to 5 dispensers in a cross pattern. This allows easy creation of large walls of dispensers. You can place redstone on dispensers by sneaking when placing.

Another use for dispensers is delaying. Using a single water current and a wooden pressure plate, you can delay a signal up to 11 seconds. The equivalent of this is 28 redstone repeaters, which is quite expensive. For even longer delays, the item despawn time can be utilised. This can be done by using a dispenser to eject an item onto a pressure plate, which then has its current inverted and wired to the next dispenser. Dispensing more than 1 item every 5 minutes will cause them to stack and no extra time will be added to the 5 minute despawn of the first item.

When powered there is a delay of 2 redstone ticks (4 game ticks) before a dispenser fires. [1]

Due to the dispenser's ability to equip armor, it is also possible to make a set of four dispensers arranged around a one block space that will equip a full set of armor all at once when a button is pressed.

Dispensers are most effectively used offensively with a 5-clock or pulser hooked up to a pressure plate or switch.

A dispenser will work if it is placed underwater, even without any blocks touching it, by placing a redstone torch underneath it. Also, it can be properly wired by placing the redstone in a tunnel underneath the water.

A mob killed by something dispensed will not drop XP.

Placing a trapped chest adjacent to a dispenser and opening the chest triggers the dispenser.

Probability distribution[editar | editar código-fonte]

Currently each stack in the dispenser is picked with equal probability. That is, if there are x stacks in the dispenser, the probability that a particular stack is picked is 1/x. Beware that the distribution isn't weighted by stack size. That skews the distribution of individual items. For example, if there are two stacks in the dispenser, one of 18 dandelions and one of 6 poppies, at first dandelions and poppies are equally likely. Poppies will run out rapidly, after which the distribution abruptly changes to 100% dandelions. Example output: Erro em Lua em Módulo:Sprite na linha 139: attempt to index field 'settings' (a nil value).

If each individual item were picked with equal probability, as if each item of a stack were in a different slot, the distribution would stay at roughly 75%/25% even over time. Indeed the output would be a uniform random permutation: Erro em Lua em Módulo:Sprite na linha 139: attempt to index field 'settings' (a nil value).

While such behavior is impossible to replicate for anything over 9 items, it can be approximated by splitting stacks such that each stack is fairly small and has the same number of items. For example, three stacks of 6 dandelions will neatly complement the stack of 6 poppies. Splitting into stacks of 3 would be even better, since smaller stacks can't retain as much 'undeserved' probability.

1.3.1 12w15a Dispensers were given the ability to place Boats and Minecarts.
12w21a Dispensers were given the ability to shoot the liquids inside water and lava buckets. They could also suck up the liquids if activated again, filling up the buckets with the liquid dropped.
12w22a Dispensers can naturally generate within jungle temples and are filled with a random amount of arrows that will shoot the player should they touch the tripwire connected to it or destroy it without shears
1.4.7 1.4.7pre Fixed crash related to arrows fired from dispensers.
[[[dinnerbonetweet:292069254017204224||January 18, 2013]]]Dinnerbone has stated that dispensers will have more features in future, so players should stick to using droppers to dispense items.
1.5 13w04a Dispensers can now face all 6 directions.
Dispensers were given the ability to use many new items. These include TNT, bone meal, flint and steel and equip armor.
13w10b Powered dispensers now do not fire if they receive a redstone update.
Em breve
1.8 14w04a Dispensers can put pumpkins on top iron/snow to make Iron and Snow Golems. This also works with Wither Skeleton Heads and Soul Sand.
14w07a Dispensers now places command blocks and runs the preset command if there's one, instead of shooting it out.
Edição de Console Legado
TU1 Added dispensers.
TU3 Dispensers use the 1.2 (12w04a) texture Ejetor.png
TU5 Added quick move to the dispenser.
TU9 Dispensers are now able to spawn mobs from a spawn egg.
They were given the ability to shoot out the liquids inside water and lava buckets. They could also suck up the liquids if activated again, but did not fill up the buckets with the liquid dropped due to a bug.
TU10 Fixed the bug where the liquid did not properly fill empty buckets.
Versão Mobile / Pocket Edition
0.14.0 Especula-se que haverá a introducão de ejetores.

Trivia[editar | editar código-fonte]

  • The texture the dispenser uses is similar to the one used by the dropper.
  • The Dispenser uses the same texture as the Furnace on all sides except the face, which has a unique texture.
  • You can use dispensers to delay Redstone circuits by intervals of five minutes, hook up a wooden pressure-plate to an i/o reverse then to a dispenser and put an item onto it. when the item vanishes then the Redstone charge will change state.
  • The texture file for the dispenser menu is named "trap.png", which suggests that it was originally designed for making arrow traps.
  • Pistons cannot push or pull dispensers, because they are tile entities.
  • It is now possible to design more compact and powerful cannons and traps with Dispensers since they can ignite TNT upon activation.
  • One can cause dispensers to drop items or fire projectiles at abnormally high speeds by powering it with an ordinary rapid pulsing circuit, with the addition of a single redstone repeater directly behind the dispenser.
  • An arrow dispenser with a stair in front of it will act as a homing dispenser, always hitting the player, but not dealing any damage.
  • If the player dies from fall damage after being hit by an arrow shot by a dispenser, the death notice will show as "<name of player> was doomed to fall by arrow."
