Assembler Table

Assembly Table

Assembly Table is a NeoForge mod for Minecraft 1.21.1 that brings back a BuildCraft-inspired assembly workflow with modern FE-based automation.

The mod adds Assembly Table machines, configurable lasers, chipset items, and scripting support for custom recipes through both KubeJS and CraftTweaker.

Machines

Assembly Table

• Crafts recipes using stored FE
• Supports a recipe queue instead of a single fixed recipe
• Accepts energy from lasers
• Pushes crafted items into the inventory above the block when possible

Powered Assembly Table

• Works like the normal Assembly Table
• Can receive FE directly from cables or other energy providers
• Does not require lasers to operate

Lasers

• Search for valid targets in front of the block
• Require line of sight to transfer energy
• Support optional warmup behavior
• Can expose laser stats in the tooltip by holding Shift

Mining and Drops

• Assembly Table and Laser blocks are mineable with a pickaxe
• They require an iron-tier tool to drop themselves

How to Use

The mod supports both KubeJS and CraftTweaker for recipe creation.

KubeJS

The custom recipe type is:

assemblytable:assembly_table

Recipe format:

{
  "type": "assemblytable:assembly_table",
  "result": { "item": "minecraft:diamond" },
  "ingredients": [
    { "ingredient": { "item": "minecraft:iron_ingot" }, "count": 2 },
    { "ingredient": { "item": "minecraft:redstone" }, "count": 1 }
  ],
  "energy": 1000
}

Example:

ServerEvents.recipes(event => {
  event.custom({
    type: 'assemblytable:assembly_table',
    result: Item.of('minecraft:diamond'),
    ingredients: [
      { ingredient: { item: 'minecraft:iron_ingot' }, count: 2 },
      { ingredient: { item: 'minecraft:redstone' }, count: 1 }
    ],
    energy: 1000
  })
})

CraftTweaker

Assembly Table recipes can be added through the global bc_assemblyTable recipe manager.

Example:

bc_assemblyTable.addRecipe(
    "my_recipe_new_ct",
    <item:mekanism:ultimate_universal_cable>,
    [
        <item:minecraft:iron_ingot> * 4,
        <item:minecraft:diamond>,
        <item:minecraft:netherite_scrap> * 6
    ],
    5000000
);

Method signature:

bc_assemblyTable.addRecipe(
    recipeId as String,
    outItem as IItemStack,
    ingredient as IIngredientWithAmount[],
    energyRequired as int
);

Developer API

Laser Configuration

Laser variants can be created through LaserConfig.builder().

Supported builder options:

• targetRange(int) – search range in front of the laser
• energyBuffer(int) – internal FE buffer
• maxTransferPerTick(int) – maximum FE sent per tick
• maxSpeedTransferPerTick(int) – alias for max transfer, useful for warmup-based lasers
• maxReceivePerTick(int) – maximum FE the laser can receive per tick
• beamColor(...) – default beam color when warmup is disabled
• warmupDisabled() – keeps classic instant transfer behavior
• warmup(int) – enables warmup for the specified number of ticks
• rampUpTicks(int) – alias for warmup(int)
• warmupColors(Vec4i low, Vec4i mid, Vec4i max) – colors for low, medium, and max speed stages

Example:

LaserConfig config = LaserConfig.builder()
        .targetRange(6)
        .energyBuffer(1000)
        .maxSpeedTransferPerTick(1000)
        .maxReceivePerTick(5000)
        .rampUpTicks(60)
        .warmupColors(
                new Vec4i(255, 40, 20, 200),
                new Vec4i(255, 220, 30, 200),
                new Vec4i(30, 100, 255, 200)
        )
        .build();

Laser Targets

Block entities that want to receive power from lasers should implement LaserTarget.

Contract:

• getRequiredLaserPower() – returns how much FE the target currently wants
• receiveLaserPower(int) – accepts FE and returns leftover energy
• isInvalidTarget() – tells lasers whether the target should be ignored

Compatibility

• JEI
• CraftTweaker
• KubeJS
