Pattern Crafter

Pattern Crafter is a Minecraft mod that adds automatic crafting machines based on patterns: you define recipes with letters (A, B, C…), set which items can go in each “cell”, and the machine crafts on its own—ideal for automation and factories. It is extremely versatile and can act both as a crafter (complex recipes, multiple patterns) and as a compacter (e.g. blocks from ingots, nuggets from ingots).

What the mod does

• Pattern Crafter (base): a block that crafts automatically using one or more patterns you configure. No energy by default; just ingredients in, results out.
• Improved Pattern Crafter: an upgraded version with RF energy, upgrade slots (more patterns, faster crafting), and more filter slots. Great for complex crafting chains.

Both blocks have:

• Input slots (27) and output slots (9), compatible with hoppers and other item transport.
• Input filters per letter (e.g. “A = stone, B = wood”).
• Output filters to forbid certain results (blacklist).
• Redstone modes: Ignore, Low, High, Pulse, Disabled.
• Shaped and shapeless recipe support (per pattern you can choose “both”, “shaped only”, or “shapeless only”).

How to use (quick guide)

1. Place the Pattern Crafter or Improved Pattern Crafter.
2. Open the GUI (use key on the block).
3. Set patterns in the 3×3 grid using letters (A, B, C, …); each letter maps to an item type you set in the filters.
4. Set input filters: for each letter used in the pattern, assign (or “mark”) the allowed item. A letter with no item assigned (“any”) can use any item that is not assigned to another letter—e.g. if A = any and B = Iron Ingot, then A will use all items except Iron Ingot (reserved for B). Assign an item to a letter to reserve that item for that cell only.
5. Optional: set forbidden outputs and redstone mode.
6. Supply the input slots (by hand or with hoppers); the machine crafts at regular intervals and puts results in the output slots.

On Improved you can also:

• Provide RF energy (e.g. with cables or compatible generators).
• Insert modules in the upgrade slots (if you use the optional Iskandert Utilities mod): logic modules = more patterns, speed modules = faster crafting.

Blocks

Block	Description
Pattern Crafter	Base machine: multiple patterns, filters, redstone. No energy or upgrades by default. Crafted with cobblestone, planks, and vanilla Crafter.
Improved Pattern Crafter	Advanced version: RF energy, logic/speed module slots, more patterns and filters. Crafted from Pattern Crafter plus gems (quartz/diamond/prismarine, lapis/glow ink).

Both appear in the Redstone creative tab.

Main features

• Multiple patterns: each machine can store several recipes (patterns); max count is configurable and, on Improved, increases with Logic Modules (optional mod).
• Letters A–Z: in the 3×3 grid you assign letters to cells; in filters you map each letter to an item type. A key with no item assigned (“any”) accepts any item that is not assigned to another letter—e.g. A = any, B = Iron Ingot: A uses all items except Iron Ingot (which is reserved for B). Assign an item to a key to reserve it for that cell only.
• Mark Input: you can “mark” input slots with an item type so the machine (and hoppers) only accept that item in that slot.
• Forbidden outputs: list of items the machine must never produce (useful to avoid unwanted recipes).
• Redstone:
  • Ignore – always craft.
  • Low – craft only when no redstone signal.
  • High – craft only when redstone signal.
  • Pulse – one craft per rising edge of the signal.
  • Disabled – never craft.
• Automation: input slots are insert-only and output slots extract-only for automation (hoppers, pipes, etc.), so you can easily hook up other mods.

Configuration

The mod adds a Common config file where you can tune, separately for Pattern Crafter and Improved:

• Maximum number of patterns
• Ticks between crafting attempts
• Energy capacity and per-craft cost (Improved by default)
• Base pattern count and max logic/speed modules
• Speed multipliers for each speed module
• Maximum number of “keys” (letters) for filters

Restart the game (or server) after changing the config.

Optional mod: Iskandert Utilities

To use upgrades on the Improved Pattern Crafter (logic module and speed module) you need Iskandert Utilities (or a compatible mod that adds the same items).
Without it the mod still works; upgrade slots simply stay empty and unused.

• Logic Module (top upgrade slot): each module adds one more usable pattern.
• Speed Module (bottom upgrade slot): only one module is used (e.g. Slow, Moderate, Fast, Extreme, Ultra); it shortens the interval between crafts (speed configurable in config).

Requirements

• Iskandert Utilities: only if you want logic/speed modules on Improved (optional)
