Description
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 (Legacy Forge / Cleanroom)
| 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)
