'''23w04a''' is the second [[Minecraft:snapshot]] for [[Minecraft:Java Edition 1.19.4]], released on January 24, 2023,<ref>{{snap|23w04a|January 24, 2023}}</ref> which adds [[Minecraft:smithing template]]s and fixes bugs.

== Additions ==
=== Command format ===
'''{{cmd|execute}}'''
* Added a new relation <code>origin</code> for {{cmd|link=none|execute on}}, which can select:
** Shooter, if the executing entity is a [[Minecraft:projectile]] (like [[Minecraft:arrow]], [[Minecraft:fireball]], [[Minecraft:trident]], [[Minecraft:firework]], thrown [[Minecraft:potion]], etc.)
** Thrower, if the executing entity is an [[Minecraft:item (entity)|item]].
** Source of effects, if the executing entity is an [[Minecraft:area effect cloud]].
** Igniter, if the executing entity is a [[Minecraft:primed TNT]].
** Summoner, if the executing entity is [[Minecraft:evoker fangs]] or a [[Minecraft:vex]].

== Changes ==
=== Items ===
'''General'''
* Enchantment glint on items and armor is now more subtle.

=== General ===
'''User interface'''
* Placeholder icons for empty slots such as [[Minecraft:armor]] or in a [[Minecraft:brewing stand]] have been lightened.
** Change has not been applied to the [[Minecraft:loom]] menu.
** Setting the resource pack to [[Minecraft:programmer art]] does not revert this change (despite the change being made to the textures themselves).

== Experimental ==
These additions and changes only take effect when the 1.20 experimental data pack is enabled.

=== Additions ===
==== Items ====
'''[[Minecraft:Smithing Template|Smithing Templates]]'''
* New item series for armor trimming and netherite upgrading, with twelve of them.
** [[File:Netherite Upgrade Smithing Template JE1 BE1.png|32px]] [[Minecraft:Netherite Upgrade]]
** Armor trims:

* They can be obtained randomly from chests generated in structures accordingly.
** Exceptions:
*** While randomly generated in other rooms, a netherite upgrade smithing template is also guaranteed in every treasure room in a [[Minecraft:bastion remnant]].
*** A single tide armor trim smithing template is sometimes dropped by [[Minecraft:elder guardian]]s upon death.
** Some armor trims are rarer.
* Consumed when used to upgrade an item in the [[Minecraft:smithing table]].
* Can not be crafted directly, but can make a copy of them by crafting in [[Minecraft:crafting table]]s as following pattern:
** 7 diamonds, shaped as iron ingots in [[Minecraft:cauldron]] crafting recipe.
** 1 block of material that the template is made out of, placed in the center slot of the crafting grid.
** 1 smithing template, placed in the remaining slot.

==== General ====
'''[[Minecraft:Data pack]]'''
* Added registry <code>trim_pattern</code> and <code>trim_material</code>, which defines trim patterns and materials respectively, to allow add them via data packs.
** These are synchronized to clients when they join the server, but the accompanying resource pack is required on client to make them visible.
** The paths to these textures are inferred based on the filename of the pattern json, and try to find the textures within the same namespace as the trim pattern's <code>name</code> field.
* <code>trim_pattern</code> defines following data:
** <code>asset_id</code>: a namespaced ID used to infer texture locations and localization.
** <code>template_item</code>: the ID of the smithing template item used to apply the trim pattern.
** <code>description</code>: a text component used for displaying the pattern name of an armor trim when hovering an armor itemstack.
* <code>trim_material</code> defines following data:
** <code>asset_name</code>: a string used as a suffix for armor trim texture locations.
** <code>ingredient</code>: the ID of the ingredient item used to apply the trim material.
** <code>item_model_index</code>: a float number which defines the item model override each armor item model should target to change their visuals for this material.
** <code>incompatible_armor_material</code>: an optional ID of the armor material this trim material cannot be applied to.
** <code>description</code>: a text component used for displaying the material name of an armor trim when hovering an armor itemstack.
*** The style defined in this description is applied to the armor trim pattern <code>description</code> as well.

'''[[Minecraft:player.dat format]]'''
* Added new flag (value 128) to <code>HideFlags</code> NBT field for hiding armor trim item tooltips.

'''[[Minecraft:Recipe]]'''
* Added <code>smithing_transform</code> and <code>smithing_trim</code> recipe serializers for the updated netherite upgrade and the new armor trim recipe respectively.

'''[[Minecraft:Resource pack]]'''
* Added <code>paletted_permutations</code>, which is a new type of atlas configuration source used to dynamically generate new textures in memory based on a set of color palettes.
** Color palettes allows to swap out the colors of a texture without having to supply all files for the variants of a texture in a resource pack.
** This is useful for things like armor trims. It can change the their color directly without create a new texture for each color.
** The <code>paletted_permutations</code> source has a set of required parameters:
*** <code>textures</code>: a list of namespaced locations of base textures.
**** These textures are used to generate variants of them that have been modified by color palettes.
*** <code>palette_key</code>: a namespaced location of a color palette key file.
**** A color palette key is used to define the set of key pixel colors we want to swap out with the color palettes defined below.
*** <code>permutations</code>: a map of permutations from suffix to a namespaced location of a color palette file.
**** The suffix is appended at the beginning to the resource location of the output variant textures, with a <code>_</code> character separating the suffix and the base texture name.
**** The color palette is a texture file with a set of pixels that are used for replacing pixels that match the color palette key in each base texture.
**** The number of pixels in each color palette must be the same as that of the <code>palette_key</code> defined for this source.
**** Key matching is done by comparing the RGB values of each pixel in the <code>palette_key</code> to the RGB values of each pixel in the color palette.
**** Alpha channel is ignored for key matching, but in the resulting texture the alpha channel is multiplied with the color palette's alpha channel.
**** Pixels that do not match the <code>palette_key</code> are copied over to the resulting texture as-is.
** After defining a <code>paletted_permutations</code> source, those namespaced output textures can be referenced in other resources in resource pack.
*** For example, if the following <code>paletted_permutations</code> source exists:
**** <syntaxhighlight lang="json">
{
"type": "paletted_permutations",
"textures": [
"minecraft:item/leather_helmet",
"minecraft:item/leather_chestplate",
"minecraft:item/leather_leggings",
"minecraft:item/leather_boots"
],
"palette_key": "minecraft:colormap/color_palettes/leather_armor_color_key",
"permutations": {
"red": "minecraft:colormap/color_palettes/red",
"green": "minecraft:colormap/color_palettes/green",
"blue": "minecraft:colormap/color_palettes/blue"
}
}
</syntaxhighlight>
*** The resulting textures can be referenced in other resources like this:
**** <syntaxhighlight lang="json">
{
"textures": {
"layer0": "minecraft:item/leather_helmet_red",
"layer1": "minecraft:item/leather_chestplate_green",
"layer2": "minecraft:item/leather_boots_blue"
}
}
</syntaxhighlight>

'''[[Minecraft:Tag]]s'''
* Added following item tags:
** <code>#trim_materials</code>: contains {{cd|d=and|amethyst_shard|copper_ingot|diamond|emerald|gold_ingot|iron_ingot|lapis_lazuli|netherite_ingot|quartz|redstone}}.
** <code>#trim_templates</code>: contains {{cd|d=and|coast_armor_trim_smithing_template|dune_armor_trim_smithing_template|eye_armor_trim_smithing_template|rib_armor_trim_smithing_template|sentry_armor_trim_smithing_template|snout_armor_trim_smithing_template|spire_armor_trim_smithing_template|tide_armor_trim_smithing_template|vex_armor_trim_smithing_template|ward_armor_trim_smithing_template|wild_armor_trim_smithing_template}}.
** <code>#trimmable_armor</code>: contains {{cd|d=and|chainmail_boots|chainmail_chestplate|chainmail_helmet|chainmail_leggings|diamond_boots|diamond_chestplate|diamond_helmet|diamond_leggings|golden_boots|golden_chestplate|golden_helmet|golden_leggings|iron_boots|iron_chestplate|iron_helmet|iron_leggings|netherite_boots|netherite_chestplate|netherite_helmet|netherite_leggings|turtle_helmet}}.

=== Changes ===
==== Items ====
'''[[Minecraft:Armor]]'''
* Now can be visually customized with a variety of unique trims at the [[Minecraft:smithing table]], except leather armor.
* Purely visual with no gameplay benefits, and can only be applied to [[Minecraft:helmet]]s, [[Minecraft:chestplate]]s, [[Minecraft:leggings]] and [[Minecraft:boots]].
** All trim patterns are visually the same on an armor's item icon, but the color still changes based on the trim material.
** The name of the trim pattern is displayed on the item's tooltip.
* Armor trim has 2 properties: pattern and material.
** Pattern: Defined by the smithing template used to apply the trim, and represents the visual pattern of the trim.
** Material: Defined by what ingredient is used to apply the trim, and represents the color of the trim.
*** Available ingredients:
**** {{ItemLink|Amethyst shard}}
**** {{ItemLink|Copper ingot}}
**** {{ItemLink|Diamond}}
**** {{ItemLink|Emerald}}
**** {{ItemLink|Gold ingot}}
**** {{ItemLink|Iron ingot}}
**** {{ItemLink|Lapis lazuli}}
**** {{ItemLink|Nether quartz}}
**** {{ItemLink|Netherite ingot}}
**** {{ItemLink|Redstone dust}}
*** Armor cannot have the same material it is made of applied to it as a trim, except for diamond armor with netherite trim being upgraded to netherite armor.

==== Gameplay ====
'''[[Minecraft:Smithing Table]] functionality'''
* Redesigned: it is now a workstation for physical equipment upgrades and modifications.
* Added a slot used by smithing templates to the left of the old 2 slots.
* Smithing templates define what type of upgrade is made to equipment.
** It specifies both what type of items that can upgrade, and which ingredients are valid to customize the upgrade.
* Netherite equipment crafting now also requires a netherite upgrade smithing template.
* Two menu types:
** Old menu without the smithing template slot has been renamed to <code>legacy_smithing</code>, and will be removed when armor trims are no longer an experimental feature.
** New menu with smithing template slot was added, called <code>smithing</code>.
