It's yet another Tuesday, and it seems that we've officially run out of quippy snapshot intros until the next delivery. Anyway, here's Snapshot 6, bringing some tweaks and improvements to the Abandoned Camp, a new World Options UI, as well as changing up how terrain is rendered.

Happy camping!

Changes

• Added a new Abandoned Camp campsite variant for each biome
• Minor tweaks to Abandoned Camp structures

UI

• Fixed an issue where Realm owners could not select automatic region preference as their Realm region
• Added a "Quit Shortcuts" option in Controls settings, which controls whether keyboard shortcuts can close the game (Alt + F4 on Windows/Linux, Cmd + Q and Cmd + W on macOS)
  • Off by default

World Options

• The World Options button has been moved to where the Open to Lan button used to be, accessible from the pause menu
  • The World Options screen is divided into two sections: "General" and "Multiplayer"
    • The "General" section contains the same options as the previous World Options screen
    • The "Multiplayer" section contains three options:
      • LAN: changes the multiplayer scope of the world
      • Command Access: Controls whether players that join your world can use commands or not
      • Port: the port number to use when opening the world to LAN
• The Online button used to access the Online Options screen will now always be shown in the Options menu

Technical Changes

• The Data Pack version is now 113.0
• The Resource Pack version is now 94.0
• Terrain blocks are now rendered with MultiDrawIndirect on supported devices

Data Pack Version 113.0

Commands

Changes to publish

• The gamemode argument has been removed
  • Instead, the default game mode of the world should be set using the defaultgamemode command or the Game Mode button in the World Options screen, while player-specific game modes should be set using the gamemode command

Data Components

Changed minecraft:cooking_fuel

• burn_time and speed_multiplier can now additionally be defined by an inline number

Changed minecraft:brewing_fuel

• uses and speed_multiplier can now additionally be defined by an inline number

Changed minecraft:compostable

• layers can now additionally be defined by an inline number

Entity Data

• Added invulnerable_time tag which makes a mob temporarily invulnerable for a specific number of ticks

Loot Table Types

Changed minecraft:block_interact

• origin is now available in context, as the center of the block being interacted with

World Generation

Noises

The format of Noises (defined in the worldgen/noise registry, or inline in noise-based Block State Providers) has been updated.

Noises define a fractal Brownian motion (fBm) configuration with the following properties:

• Produces output values (approximately) fitting a normal distribution

• Unless otherwise specified, fits the output amplitude to [-1; 1]

  • Due to the normal distribution, in practice this means that 99.7% of all samples will fit in that range - but values may still be encountered outside of this range

• Parameterized by persistence=0.5, lacunarity=2.0

  • i.e. between each octave, the amplitude is halved and the frequency doubled

• Has stable seeding such that an octave can be boosted, muted, or added without affecting the rest of the octaves

• Renamed firstOctave to base_octave

• Added base_amplitude - non-negative float, a scale factor to apply to the noise output

  • If not specified, defaults to 1.0

• Added octave_count - integer between 1 and 32, the number of octaves to sample

• Added normalize - boolean, or "legacy", controls how the output amplitude should be normalized

  • If true, base_amplitude is the expected amplitude of the output (i.e. 99.7% of all samples in [-base_amplitude; base_amplitude])
  • If false, base_amplitude is the amplitude of the first octave
  • If "legacy", inherits the same normalization behavior as expressed by the previous format
    • This would generally fit to a range smaller than expected
  • If not specified, defaults to true
  • Note: normalization is not affected by the amplitude_modifiers field - as such, modifying the amplitude of a single octave will not affect the amplitude of others

• Renamed amplitudes to amplitude_modifiers - list of floats, a scaling factor to apply to each octave

  • The number of elements in this list must match octave_count
  • As described above, this scaling factor bypasses normalization and will affect the output amplitude
  • This field is no longer required - if not specified, defaults to all 1.0

Density Functions

Added pow

Raises the given base value to an exponent.

Format: object with fields:

• base - Density Function, the base value
• exponent - Density Function, the exponent

Added sqrt

Computes the square root of the given input.

Format: object with fields:

• input - Density Function, the value for which to compute the square root

Added log

Computes the natural logarithm of the given input.

Format: object with fields:

• input - Density Function, the value for which to compute the natural logarithm

Added sign

Computes the sign of the input:

• If the input is positive, returns 1
• If the input is 0, returns 0
• If input is negative, returns -1

Format: object with fields:

• input - Density Function, the value of which to compute the sign

Added distance_to_point

Computes the distance to a fixed point using the specified distance function.

Format: object with fields:

• point - array of 3 integers in form [x, y, z], the point to compute distance to
• metric - one of:
  • euclidean - i.e. sqrt(dx^2 + dy^2 + dz^2)
  • euclidean_squared - i.e. dx^2 + dy^2 + dz^2
  • manhattan - i.e. abs(dx) + abs(dy) + abs(dz)
  • chebyshev - i.e. max(abs(dx), abs(dy), abs(dz))

Updated gradient (renamed from y_clamped_gradient)

Format: object with fields:

• axis - x, y, or z, the axis over which to define this gradient
• tiling - one of:
  • clamp_to_edge - outside the gradient boundaries, the value at the nearest boundary will be used
  • repeat - the gradient will be repeated outside its boundaries
  • mirrored_repeat - the gradient will be repeated such that odd repetitions are mirrored, ensuring continuity between repetitions
• from_coordinate - int, the coordinate at which the gradient starts
• to_coordinate - int, the coordinate at which the gradient ends
  • Must not be equal to from_coordinate
• from_value - float, the value at which the gradient starts
• to_value - float, the value at which the gradient ends

Added slice

Removes a dimension from the input domain by taking a "slice" along an axis with a specific coordinate. For example, with axis=y and coordinate=0, a slice will be taken along the XZ plane, with all values sampled at y=0.

Format: object with fields:

• axis - x, y, or z, the axis to remove
• coordinate - int, the fixed coordinate to be passed to the input function
• input - Density Function, the input function

Changed end_outer_islands

Renamed from end_islands. No longer computes the density of the main island.

Structure Pool Elements

Changed minecraft:feature_pool_element

• Can now connect to Jigsaw blocks with any target name, instead of just minecraft:bottom

Resource Pack Version 94.0

Shaders & Post-process Effects

• terrain.vsh and terrain.fsh shaders are refactored to support multi-draw
• Some of the members in Globals and DynamicTransforms are shuffled to use less memory for those uniform blocks
• Introduced new define: RENDERPEARL_EXPLICIT_DEPTH_INVARIANCE - If present, indicates that an OIT shader should explicitly output a depth value because a device it is running on can produce a slightly different implicit value

Equipment Assets

The trim_palette_replacements field has been replaced with trim_overrides. This can be used to swap out the texture or palette used with specific trim materials or patterns for a given equipment asset, not just swap specific palettes.

• Format: list of override entries with fields:
  • when - object with fields, the material and/or pattern to match
    • material - optional Trim Material ID, the material to match (if specified)
    • pattern - optional Trim Pattern ID, the pattern to match (if specified)
      • Note: this is not the palette ID, as trim_palette_replacements used to be!
    • At least one of material or pattern must be specified
    • If both are specified, both must match for the entry to be used
  • texture - optional trim pattern asset ID, a replacement texture to use if this entry matches
    • Textures are specified in the same format as asset_id
    • If not specified, the default texture for the pattern will be used
  • palette - optional palette ID, a replacement palette to use if this entry matches
    • If not specified, no palette remapping will be applied to the texture
  • The first matching entry will always be selected
  • At least one of texture or palette must be defined
