MustJS

MustJS is a KubeJS addon designed to simplify the creation and management of Create mod recipes through a collection of reusable JavaScript functions. The addon provides ready-to-use functions for common Create processing recipes, sequenced assembly, fluid manipulation, and item manipulation, allowing you to create complex recipes with cleaner and more organized scripts.

MustJS is intended to be used as a library for your KubeJS scripts.

---

📂 Structure

The MustJS folder contains all the functions required to create your recipes. You should treat this folder as a library and use its functions inside your recipe scripts.

⚠️ Do not edit the MustJS files directly.
The library is frequently updated, and your changes may be overwritten when updating the addon.

🛠️ Creating Recipes

To create recipes using MustJS, create a new .js file inside your KubeJS recipe scripts and register your recipes using:

ServerEvents.recipes(event => {
    // Your recipes here
})
All MustJS recipe-generation functions require the **`event`** parameter.
Example

js ServerEvents.recipes(event => { compacting( event, itemOutput('minecraft:diamond'), [itemInput('minecraft:coal'), itemInputTag('minecraft:logs')], 'heated' ) })

📜 Functions
CreateBaseFunctions
Functions for creating common Create processing recipes.



Function
Description

cutting(e, output, input, time)
Creates a cutting recipe


deploying(e, output, held, base, keep)
Creates a deploying recipe


emptying(e, output_item, output_fluid, input)
Creates an emptying recipe


filling(e, output, input, fluid)
Creates a filling recipe


haunting(e, output, input)
Creates a haunting recipe


item_application(e, output, input_block, input_item)
Creates an item application recipe


mechanical_crafting(e, output, input, pattern)
Creates a mechanical crafting recipe


milling(e, output, input, time)
Creates a milling recipe


mixing(e, output, input, heat)

pressing(e, output, input)
Creates a pressing recipe


polishing(e, output, input)
Creates a polishing recipe


splashing(e, output, input)
Creates a splashing recipe


sequenced_assembly(e, output, input, transitional, loops, processing)
Creates a sequenced assembly recipe




⚙️ Sequenced Assembly
MustJS also provides auxiliary functions specifically designed to simplify the creation of Create's Sequenced Assembly recipes.
Auxiliary Processing Functions

js cuttingS(output, input, time) deployingS(output, held, base, keep) fillingS(output, input, fluid) pressingS(output, input)

These functions can be combined inside `sequenced_assembly()` to build complex processing chains.

💧 FluidManipulator
Functions for easily defining fluid inputs and outputs.
Functions

js fluidOutput(fluid_id, fluid_amount) fluidInput(fluid_id, fluid_amount)

### Example

js fluidInput('minecraft:water', 1000)

---
📦 ItemManipulator
Functions for defining item inputs and outputs.
Output Functions

js itemOutput(id) itemOutputStack(id, count) itemOutputChance(id, chance) itemOutputChanceStack(id, chance, count)

### Input Functions

js itemInput(item) itemInputTag(tag) itemInputKey(symbol, id) itemInputTagKey(symbol, tag)

These functions make it easier to define regular items, item stacks, item tags, and keyed ingredients for recipe generation.

🔧 Example
A basic MustJS recipe script can look like this:

js ServerEvents.recipes(event => {

haunting(
    event,
    itemOutputStack('minecraft:iron_ingot', 12),
    itemInput('minecraft:iron_block')
)

}) ``` MustJS manages the recipe structure, allowing you to focus on what the recipe should produce rather than manually writing the entire creation recipe definition. All functions come with proper documentation and usage explanations, as well as error handling to assist in developing your recipes!
