Minecraft:Number provider

Template:For Template:Exclusive Template:Update Template:Wip A number provider is a data structure used to provide a number, which can be simply a constant, a random number within a certain distribution, a number under a certain condition, etc. Number providers are used in Minecraft:loot tables, Minecraft:predicates, Minecraft:item modifiers, villager trade, Minecraft:trade sets, the compute command, and in data components (Template:DCL, Template:DCL, and Template:DCL).

Use

Number providers are used in Minecraft:loot tables, Minecraft:predicates, Minecraft:item modifiers, villager trade, and Minecraft:trade sets.

Number provider Minecraft:registry can be used in the components Template:DCL, Template:DCL and Template:DCL. In this case, only number providers and constants are accepted, not inline definitions.

Format

Template:UpdateTemplate:Incomplete section A a number provider can be an Template:Nbt or Template:Nbt. They can either be defined as a constant value or as an object.

• Template:Nbt: Constant number provider.

Or:

• Template:Nbt: The root tag. Shorthand for a uniform distributionTemplate:Until.
  • Template:NbtTemplate:Nbt: Number provider. The minimum value.
  • Template:NbtTemplate:Nbt: Number provider. The maximum value.

Or:

• Template:Nbt: Namespaced ID pointing to an element of number provider Minecraft:registry. See Template:Slink.

Or:

• Template:Nbt: The root tag.
  • Template:Nbt: The number provider type as a Minecraft:resource location. .
  • Extra fields of the number provider, described below.

Number providers types

Template:Past Each type of number provider specifies the rules by which the number will be provided. To do this, they use associated extra contents, which function differently for each type.

The type values can omit or include the namespace Template:Cd, for example using the type Template:Cd or Template:Cd has the same effect.

Number provider types can not be customized via data packs.

Each type has two ways to get a number: an Minecraft:integer or a Minecraft:float.

Integer Providers

These can be used in Template:Cd

Abs

Returns the absolute value of the input.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:Nbt: The number to take the absolute value of

Avg

The mean of all inputs. Note this rounds towards 0.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:Nbt: The numbers to take the mean of

Binomial

A random number following a binomial distribution. The returned float has the same value as the int.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:NbtTemplate:Nbt: Number provider. The amount of trials.
  • Template:NbtTemplate:NbtTemplate:Nbt: Number provider. The probability of success on an individual trial.

Conditional

Returns the value from Template:NbtTemplate:NbtTemplate:Nbt if its Template:NbtTemplate:Nbt is met or Template:NbtTemplate:NbtTemplate:Nbt if not.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:Nbt: A Minecraft:predicate to test which value will be returned.
  • Template:NbtTemplate:NbtTemplate:Nbt: A number provider, which runs if the Template:NbtTemplate:Nbt is met.
  • Template:NbtTemplate:NbtTemplate:Nbt: (Optional. Default Template:Cd) A number provider, which runs if the Template:NbtTemplate:Nbt is not met.

Constant

A constant value.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:Nbt: The exact value.

Sub

Subtracts Template:NbtTemplate:NbtTemplate:Nbt from Template:NbtTemplate:NbtTemplate:Nbt and then returns that value

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:NbtTemplate:Nbt: The left of the equation
  • Template:NbtTemplate:NbtTemplate:Nbt: The right of the equation
    

Uniform

A random number following a uniform distribution between two values. The values are inclusive, meaning the provided number can be either Template:Cd or Template:Cd, except if the provided number is a float, in which case it must be strictly less than Template:Cd. If Template:Cd ≤ Template:Cd, the provided number is Template:Cd.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:PastTemplate:Nbt: Number provider. The minimum value (Template:Cd).
  • Template:PastTemplate:Nbt: Number provider. The maximum value (Template:Cd).

Score

To query and use a Minecraft:scoreboard value.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:Nbt: To choose which player name or entity UUID to query. (Must be an object unless specifying an entity from loot context using the same options as Template:Nbt)
    • Template:Nbt: Set to Template:Cd to manually specify a player name or UUID. Set to Template:Cd to use an entity from loot context.
    • Template:Nbt: Included only if Template:Nbt is set to Template:Cd. Specifies the name of the player, or the entity's UUID (in hypenated hexadecimal format) whose score to query.
    • Template:Nbt: Included only if Template:Nbt is set to Template:Cd. Specifies an entity from loot context to query the score of. Can be Template:Loot entity target
  • Template:Nbt: The scoreboard objective to query on the selected player name or UUID.
  • Template:PastTemplate:Nbt: (Optional. Default Template:Code) The value to return if Template:Nbt or Template:Nbt do not exist.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:Nbt: Minecraft:Level-based value calculating the value based on the enchantment.

Add

The sum of multiple value providers

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:Nbt: List of number providers to sum.

Mul

The product of the multiplication of multiple value providers

• Template:Nbt
  • Template:Nbt: Template:Cd

This provider requires a context with an origin position set as long as the environment attribute can vary positionally.

  • Template:Nbt: An environment attribute ID to fetch.

Number dispatcher

Returns the first case which fulfills its condition or the default if none do.

  • Template:Nbt: A list of cases in the order that the dispatcher will try to execute them.
    • Template:Nbt: A single case:
      • Template:NbtTemplate:Nbt: A Minecraft:predicate to be tested in this case.

Weighted list

Returns a value from a distribution of weighted number providers.

• Template:Nbt
  • Template:Nbt: Template:Cd
  • Template:Nbt: Returns a value from a distribution of weighted number providers.
    • Template:Nbt: A single weighted number provider:
      • Template:PastTemplate:Nbt: A number provider, which is executed if the weighted number provider is chosen.
      • Template:Nbt: A positive integer. Determines how often this weighted number provider is chosen out of all data in the distribution. Weighted number provider with higher weights are used more often. The chance of an weighted number provider being chosen is [this weighted number provider's weight ÷ total weight of all weighted number provider in the distribution].
