Introduction
Minecraft became one of the most fascinating games for video game lovers. Various tools, weapons, vehicles, raw materials, anvils and dispenser etc. can be used while mastering various levels of this game. Minecraft dispenser is a block or an item that is used to dispense or shoot the objects, depending on what materials are kept inside. You can simply click the right button of your mouse to place the items inside. Dispenser dispenses an item if it receives some power from a red stone circuit. On activating the dispenser, most of the items will normally drop out.
On the other hand, snowballs, arrows, and eggs etc. will be fired out. Redstone circuits are generally used for powering a dispenser. However, all items present inside are not dispensed uniformly, and items at the bottom of the right side are much more than that to the top left. A dispenser is a type of block that is powdered with special Redstone. On clicking right button of the mouse, you will be allowed to place items inside it. The block receives power via Redstone circuit with dropping out of random item from its inventory. Dispenser looks like droppers and furnaces, but all three blocks have distinct uses and crafting procedure. Dispenser can even attack things.
Chapter 1. Dispensing
Dispenser has a major function of dispensing the items. The precise action of the dispenser depends on the items enclosed in it. Generally, most of the items are ejected as items and land 3 by 3 blocks away on ground level similar to the items that the player drops. Similarly, we can place the Heads and Pumpkins. Command blocks are even placed with their Tile Entity data. On the other hand, Arrows, Snowballs, Chicken Eggs, Splash potions, Fire Charges, Bottles O Enchanting, Firework Rockets etc. are fired outside with a right click.
Upon firing the arrows from 2 upper ground level, they can go anyplace from 10 to 21 blocks away. The optimal range of the fired arrows for mob killing is about 1 to 5 blocks including a hit ratio of about 98% at the power of the 5 block range on a target having the size of a standard mob. Arrows can create about 1.5 hearts of damage and are also selected, dissimilar to those fired by skeletons.
- The arrows fired from a dispenser present at the top layer (not facing up or down) travels a maximum about 80 blocks away from the dispenser before reaching the ground on the bottom layer.
- The arrows fired from 1 block above the ground level can travel anywhere from 6 to 13 blocks away.
Snowballs and chicken eggs will break with most common effects. The mobs hit by the dispenser shooting any projectile will not be rejected; it is uncertain whether this is a bug or not.
- Fire Charges will continue in a straight line becoming fireballs of same type as Blaze fireballs. Upon being dispensed, the fire charge will produce the similar sound as Ghasts and Blazes when they start their projectile. But if it is used by the player, it produces similar sound as Flint and Steel.
- Spawn Eggs will result in the respective mob being formed with its feet in the block directly, which is in front of the dispenser, with no initial velocity.
- If the dispenser is kept above the water or on a rail, Boats and Minecarts will be kept exactly as in their entity form.
- Water and lava source blocks are kept in Water and lava buckets. These sources are also taken if any empty bucket is present inside. Water couldnt be placed if the dispenser is below.
- A player from 1 block away can equip the armour.
- Bone Meal can be used on the pointed crops.
- Fire will be ignited in front of the dispenser consuming individual durability via Flint and Steel.
- TNT will explode and is kept with no exact forward velocity. But when they are dispensed, they might move at very minor rate in a random path before falling straight down. TNT will gain a good chance of narrowly losing the hole if you attempt to drop TNT by means of the dispenser above a one block by one block hole. As a result, an extra care must be put in delicate machines necessitating TNT and dispensers.
All fired out items possess a random variation in direction. When an item is dispensed using a dispenser, a clicking sound (if only the item is Spawn egg or a projectile) and a puff of smoke is emitted. If it is emptied during activation, a slightly higher-pitched click will be heard.
Chapter 2. Triggering
Instead of most other redstone devices, a redstone wire placed up to one nearby block may also be used for triggering. About 5 dispensers can be triggered by only one redstone wire in a cross pattern. This enables easy generation of large walls of dispensers. Redstone can be placed on dispensers by sneaking while placing.
Moreover dispensers can also be used in delaying. Delaying a signal up to 11 seconds can also be done by the help of single water current and a wooden pressure plate. The corresponding of this is 28 redstone repeaters, which is more expensive. Item de-spawn can be used well for longer delays. A dispenser can be used to eject the item onto a pressure plate, which then inverts its current and wires to the next dispenser. Dispensing 2 or more than 2 items in each 5 minutes will create stack between them and no extra time will be provided to the 5 minutes de-spawn of the first item. Before firing a dispenser while powdering causes a delay of 2 Redstone ticks.
Dispenser has the ability of equipping the armour that makes it possible to create a set of 4 dispensers arranged around a block space that can be implied to equip a full set of armour at once after you press a button. Dispenser can be used more effectively with a 5-clock or pulser hooked up to a pressure plate/switch. Dispenser will even work inside water freely without the touch of any blocks by fixing a redstone torch below it. Proper wiring of it can also be done by keeping the redstone in a tunnel below the water. XP will not be dropped by mob killed by something dispensed. You can place a trapped chest next to a dispenser and open the chest for triggering.
Chapter 3. Probability Distribution
Every stack in the dispenser is picked with the same probability. For example, if x number of stacks are present in the dispenser, then the probability of picking a particular stack is 1/x. Besides that, distribution is not weighted by size of the stacks. This twists the distribution of respective items. For example, if 2 stacks are present in the dispenser, one (18 dandelions) and one (6 poppies), initially dandelions and poppies are equally similar. Poppies will run out suddenly, which results the change of distribution to 100% dandelions. If every item of stack were kept in different slot likewise, if each individual item were picked with same probability, the distribution would be 75%/25% or even more. As a result, the output would be a uniform random variation.
