Warfactory Ultimate Weight

WarFactory Ultimate Weight is a multi-version Minecraft mod focused on inventory weight, movement penalties, and stamina.

It is designed around performance-first inventory tracking rather than the brute-force full inventory iteration used by many older weight mods and predecessors.

It is built around a shared core with version-specific runtime hooks. The mod currently targets:

Minecraft	Loaders
1.12.2	Legacy Forge
1.20.1	Fabric, Forge
1.21.1 (planned)	NeoForge, LexForge

Features

• Configurable item and inventory weight system
• HUD and tooltip weight display
• Weight-based movement and jump penalties
• Hard-lock threshold for blocking pickups and transfers
• Config sync from server to client
• Delta-based inventory weight updates where supported
• Stamina system with: totalStamina, staminaLossRate, staminaGainRate
• Weight-aware stamina drain penalties
• Optional stamina drain from sprinting and jumping
• Nested inventory weight support
• Mod compatibility patches and API for mod developers

Supported Mods

Ultimate Weight reads the contents of modded storage items so an item's weight scales with what it holds, and counts items worn in extra equipment slots (Baubles / Curios). Any item that exposes a standard item-handler capability is supported automatically; the mods below additionally get dedicated handling for their custom storage. Compatibility patches load only when the target mod is present and are safe when it is absent.

1.12.2

Mod	Supported
Baubles	Worn bauble items counted toward weight
Traveler's Backpack	Worn + carried backpack contents
Retro Sophisticated Backpacks	Backpack contents and installed upgrades
GregTech (CE Unofficial)	Machine / item inventories
HBM's Nuclear Tech	Storage crate contents
Storage Drawers	Drawer contents
Any item with an IItemHandler	Nested contents counted generically

1.20.1 (Forge)

Mod	Supported
Curios	Worn curio items counted toward weight
Sophisticated Backpacks	Worn (Curios/chest) + carried contents, click-to-stash
Traveler's Backpack	Worn + carried backpack contents
GregTechCEu Modern	Machine inventories, including crates
Superb Warfare	Ammo box (per-type ammo counts)
Storage Drawers	Drawer contents
Any item with an IItemHandler	Nested contents counted generically

The same registry the patches use is exposed as a public API, so other mods can register their own weight providers. On the 1.20.1 Fabric build, vanilla nested containers are counted, but the mod-specific handlers and the generic item-handler reader above are Forge-only. (Subject to change)
