MT-Recipex

MT-Recipex is an advanced developer API mod for Minecraft 1.21.1 (NeoForge). It restores the recipe registration directly from Java, inspired by old version 1.7.10 (GameRegistry.addRecipe).

🚀 Key Features & Advantages

Full JEI (Just Enough Items) Compatibility: Because recipes are hot-swapped directly into the engine via a Mixin, JEI completely reads and correctly renders them across all appropriate tabs (including drop chances, processing time, and heat requirements).
Type Safety: Strict Java Enums (CreateRecipeType, HeatLevel…) instead of strings prevents typos.

🛠️ Supported Recipe Types

1. Vanilla Recipes (Crafting Table, Furnace, Smithing Table)

Shaped (addShaped): Traditional 1.7.10 grid layout style ("DDD", "DID") followed by symbol definitions.
Shapeless (addShapeless): Simple ingredients list (up to 9 items) that the player can throw anywhere into the crafting grid.
Furnace / Cooking (Smelting, Blasting, Smoking, Campfire Cooking): Support for the regular furnace, blast furnace, smoker and camp fire.
Smithing Table (addSmithingTransform): Full specification of the modern smithing upgrade layout requiring a Template, a Base item, and an Addition ingredient.

2. Create Mod Processing

Single-Ingredient Machines (addCreateProcessing): Pressing, sandpaper polishing (PRESSING, SANDPAPER_POLISHING).
Time-Dependent Machines: Crushing and cutting (CRUSHING, CUTTING, MILLING,HAUNTING, SPLASHING) with an optional explicit processingTime parameter.
Output Chances (CreateOutput Record): Create processing outputs accept an array of CreateOutput objects, combining an ItemStack and a float drop chance (from 0.0F to 1.0F).

3. Basin based Create Machines (Mixing & Compacting)

Mixing and Compacting (addCreateAdvanced): Multi-ingredient support for MIXING and COMPACTING.
Combined Inputs & Outputs: Accepts arrays of clean ItemLike objects and NeoForge FluidStack liquids on the input side, matching CreateOutput objects and FluidStack liquids on the output side.
Heat Requirements (HeatLevel Enum): Recipes can be strictly restricted to a specific Blaze Burner status: NONE, HEATED, or SUPERHEATED.
Filling & Emptying (addCreateFilling, addCreateEmptying): Fluid-container interactions handled programmatically.
Mechanical Deployer (addCreateDeploying): Simulates a deployer hand clicking an item onto a base block moving on a belt.
Item Application (addCreateItemApplication): Right-clicking an item onto a specific block (e.g., creating Casings).
Mechanical Crafting (addCreateMechanicalCrafting): Large crafting grids (5x5 and above) hooked up to shafts, featuring a toggleable acceptMirrored parameter.

4. Sequenced Assembly

addCreateSequencedAssembly: Used for Precision Mechanisms and high-tech components.
Complete Sub-Step Automation: Manually coding JSONs for sequences is extremely tedious in 1.21.1 MT-Recipex handles all of this automatically behind the scenes! You only define the steps in their natural order.
Built-in Step Factory Methods: stepPressing(), stepCutting(time), stepFilling(FluidStack), stepDeploying(ItemLike).

5. Custom Raw JSON Recipes

Custom (addCustom): Allows you to build and inject a completely raw JsonObject for any custom recipe type from other mods that are not natively supported by the API.
