Minecraft Snapshot 24w18a

A Minecraft Java Snapshot

Because it's the month of May, may we tempt you with the first Snapshot for Java Edition 1.21? This one looks as excellent as it sounds, thanks to the 20 new paintings and 3 new music discs it adds to the game. And we're not stopping there, data-driven enchantments are also being thrown into the fray with this Snapshot (hence the 900+ line changelog). We also included a batch of new bug fixes for good measure.

Happy mining!

Enchantments

Enchantments are now set through data. An Enchantment is a set of core properties like level ranges and cost together with some effects. Most effect types also support a set of conditions, making it possible to apply them only when certain criteria are met.

Enchantments can be added in the registry enchantment. All Vanilla Enchantments can be found in the vanilla datapack in the client and server jar files.

Fields:

  • description: The name of the Enchantment when displayed in text represented as a Text Component

Level-Based Values

Many effects of Enchantments depend on the level of the Enchantment. For these fields, a type called Level-Based Values is used. In their most basic form, Level-Based Values can be written as floating-point constants, which is interpreted as a value that isn't in fact level-based, the constant is used as-is for all levels.

If a Level-Based value is not a floating-point constant, it is an object with a type field, specifying one of the following types.

linear

The most common type of Level-Based Value is a linear value. A linear Level-Based Value has two fields:

  • base: The base value added to all levels
  • per_level_above_first: Amount added for each level above the first one

In effect, a linear Level-Based Value results in base + per_level_above_first * (level - 1).

clamped

A Level-Based Value type that clamps a value between a min and max. Fields:

  • value: A Level-Based Value used as the input
  • min: A floating point value specifying the minimum value of the output
  • max: A floating point value specifying the maximum value of the output
fraction

A Level-Based Value type that represents the fraction between two values. Fields:

  • numerator: A Level-Based Value used as the numerator
  • denominator: A Level-Based Value used as the denominator
levels_squared

A Level-Based Value type that evaluates to the square of the levels, plus an addition. Fields:

  • added: A floating-point value added to the result of the squared levels

In effect, a levels_squared Level-Based Value results in level ^ 2 + added

Value Effect Types

Value Effects are effects used to manipulate the amount of something in the game.

A Value Effect that overwrites the input value with a given Level-Based Value.

Fields:

  • value: The Level-Based Value to use as the result

Attribute Effects

Attribute effects use the Attribute system to apply an Attribute Modifier whenever the Enchanted Item is correctly equipped. Attribute effects do not have a dynamic type - they are all the same type.

Fields:

  • name: The name of the Attribute Modifier to add
  • attribute: The ID of the attribute to modify
  • operation: The operation of the Attribute Modifier

Location-Based Effect Types

Location-Based Effects are special effects that activate and deactivate depending on where the owner of the Enchanted Item moves. Location-Based Effect only trigger when such items are initially equipped and subsequently when the owning Entity moves to a new space in the Block grid - i.e. when their coordinates change to a new integer value.

All Entity Effect types can also be used as Location-Based Effects, and in addition attribute can be used to specify an Attribute Effect as a location-based effect.

Effect Conditions

Most Enchantment effects are filtered using Conditions (same types as in loot tables). This enables effects to be specific for different situations. Each Effect Component defines which parameters are available for the condition to evaluate - some parameters are available for all of these parameter sets, while some are specific to a certain set.

Each effect component specifies which parameters are available in the Effect Components list below.

Damage Parameters
  • Entities: this, attacker, direct_attacker
  • Enchantment Level
  • Origin
  • Damage Source
Item Parameters
  • Tool

Effect Components

The effects field in an Enchantment is a map of Effect Component type the Effect List data. Most Effect Components are lists, so any number of Effects can be added of any Component Type. The data for each effect generally involves having a specified condition context and Effect Type, but some Effects also deviate from this format.

In cases where the documentation specifies a Condition Context and Effect, the Component is a list. Each entry in the list has a field named effect with the effect of the type used by the list. Entries can also optionally include a field named requirements specifying the condition parameters, which are then evaluated with the documented context.

trades/<biome>_<profession>_<equipment>_<level>

For example: trades/desert_armorer_helmet_4 and trades/taiga_armorer_chestplate_5.

Enchantment Provider Types

single_enchantment

An Enchantment Provider which always provides the same Enchantment. The level of the Enchantment can be either constant or randomized.

Fields:

  • enchantment: Namespaced ID of the Enchantment
  • level: Int provider representing the level of the Enchantment
enchantments_by_cost

An Enchantment Provider which gives one or more Enchantments from a set of options according to a given cost (similar to the cost value in the Enchantment Table).

Fields:

  • enchantments: The set of Enchantments as either a single Enchantment, a list of Enchantments or hash-prefixed Enchantment Tag
  • cost: Int provider representing the cost to use for the Enchanting process
enchantments_by_cost_with_difficulty

An Enchantment Provider which works like enchantments_by_cost, but where the cost is calculated partially based on the local difficulty of the area where the event happens causing the Enchantments to be added.

How efficiently the entity can move through impeding terrain that slows down movement. A factor of 1 removes all movement penalty, a factor of 0 applies full movement penalty.

  • Default: 0
  • Minimum: 0
  • Maximum: 1

generic.oxygen_bonus

Factor to the chance an Entity has to not use up air when underwater. 0 has no effect, values over 0 are used in the following formula to determine the chance of using up air:

1 / (oxygen_bonus + 1)

  • Default: 0
  • Minimum: 0
  • Maximum: 1

generic.water_movement_efficiency

The movement speed factor when submerged. The higher, the more of the underwater movement penalty is mitigated. Note that this represents only the submersion factor itself, and other factors (such as not touching the ground) also apply.
