Description

Backport of Functional Storage features for Minecraft 1.12.2 (Forge).

Implemented Features

Compared with traditional 1.12.2 drawer mods, this project is closer to modern Functional Storage interaction patterns:

  • Storage upgrades use a multiplicative scaling model
  • Drawer contents, upgrades, and config are preserved in item NBT after block break
  • Drawer items can expose IItemHandler capability for cross-mod interaction
  • Collector upgrade supports both dropped-item and fluid collection behaviors

Main Content

Drawers and Storage Blocks

  • Wooden drawers: 1x1, 1x2, 2x2
  • Wood types: oak, spruce, birch, jungle, acacia, dark_oak
  • Compacting Drawer: 3-tier compacting storage
  • Simple Compacting Drawer: 2-tier compacting storage
  • Fluid Drawer: 1 / 2 / 4-slot fluid variants
  • Ender Drawer: frequency-based shared single-slot storage
  • Storage Controller
  • Controller Extension
  • Armory Cabinet

Upgrade System

Storage Upgrades

  • Iron Downgrade
  • Copper Upgrade
  • Gold Upgrade
  • Diamond Upgrade
  • Netherite Upgrade
  • Creative Vending Upgrade

Notes:

  • Storage upgrades are calculated multiplicatively instead of single-tier overwrite
  • Default multipliers: copper x8, gold x16, diamond x24, netherite x32
  • Upgrades affect normal storage, fluid capacity, and controller range calculations
  • If removing an upgrade causes stored amount to exceed new capacity, that slot is locked and cannot be extracted directly
  • If holding a higher-level storage upgrade, it can still directly replace a lower-level one
  • Upgrade conflict checks are centralized (for example, Void Upgrade cannot be installed more than once)

Functional Upgrades

  • Void Upgrade
  • Redstone Upgrade
  • Pulling Upgrade
  • Pushing Upgrade
  • Collector Upgrade

Notes:

  • Void Upgrade discards overflow of matching items/fluids
  • Redstone Upgrade outputs signal based on fill ratio
  • Pulling / Pushing interact with adjacent item/fluid capabilities
  • Collector Upgrade collects dropped items from the block in front and collects fluids at a slower interval
  • Directional functional upgrades store facing in upgrade item NBT; sneak-right-click to cycle direction

Storage Features

Normal Drawers

  • Uses a high-capacity item handler; each slot can hold far more than vanilla 64
  • Item matching preserves metadata and NBT
  • Supports template retention when locked

Compacting Drawers

  • Automatically detects compacting/decompacting recipes
  • Supports initialization from any valid tier
  • Automatically converts total amount across multi-level outputs

Fluid Drawers

  • Each slot stores only one fluid type
  • Supports direct interaction with buckets and fluid containers
  • Locked slots retain fluid templates

Ender Drawers

  • Uses frequency strings for shared storage
  • Drawers with the same frequency share the same inventory
  • Does not support storage upgrades

Armory Cabinet

  • High-capacity storage for non-stackable equipment/tool items
  • Default capacity: 4096 slots
  • Independent from controller and drawer upgrade systems

Controller Network

Storage Controller

  • Aggregates item and fluid capabilities from connected drawers
  • Prioritizes already-matched/locked drawers on insertion
  • Controller range is affected by storage upgrade calculations

Controller Extension

  • Provides additional access points for a controller network
  • Can connect to adjacent controllers or already-connected extension blocks

Tools

Linking Tool

  • Right-click controller: record target controller
  • Right-click drawer: add or remove connection
  • Supports single mode and area batch mode
  • Supports add/remove mode switching
  • Also used to copy and set Ender Drawer frequency

Configuration Tool

  • Sneak-right-click air: cycle modes
  • Right-click drawer or controller: apply current mode
  • Supported modes include:
    • Lock
    • Number Display Toggle
    • Item Render Toggle
    • Upgrade Icon Toggle
    • Indicator Bar Mode

Item Form Capabilities and Tooltip

  • When a drawer block is broken or middle-click picked, contents and upgrades are written into item TileData
  • Normal drawer items and compacting drawer items expose IItemHandler capability
  • Other mods can interact with drawer items as containers
  • Tooltip displays stored content and amounts
