Encumbrance
Encumbrance adds a configurable inventory weight system. Items and blocks have weight, and carrying too much can slow you down. Supports vanilla defaults, modded items, decimal weight values, and an optional realism mode.

About this project
What does Encumbrance add?

Ever come back from a mining trip carrying half a mountain, a backup pickaxe, enough food for a week, and somehow still sprint home like nothing happened?
Encumbrance changes that.
This mod adds a weight system to your inventory, making what you carry actually matter. Stone, ores, tools, armor, building materials, loot… it all adds up. The more you load yourself down, the more you'll start to feel it.
Not in an annoying way. Not with arbitrary restrictions. Just enough to make you think a little more about what you're bringing with you before heading out.
What It Does
Every item in your inventory has a configurable weight value.
That includes:
Blocks
Tools
Weapons
Armor
Food
Resources
Modded items
Light items barely affect you.
Heavy loads start slowing you down.
That stack of cobblestone you swore you'd need? It might start feeling like a bad idea.
Weight Ranges
Weight values use a configurable range from 0.0 to 3.0.
Examples:
0.1 → Feathers, seeds, paper
0.5 → Food, leather, wool
1.0 → Most everyday items
2.0 → Stone, logs, ores
3.0 → Anvils, obsidian, metal blocks
Everything can be adjusted to fit your pack.
Want a harsher survival experience?
Make iron hurt.
Want a more relaxed adventure pack?
Tone it down.
Optional Realism Mode
For players who want survival to feel a little rougher.
Optional realism settings can increase the impact of heavy loads with things like:
Stronger movement penalties
Reduced sprint efficiency
Slight jump reduction
Entirely optional.
Turn it on if you want the extra challenge.
Leave it off if you just want smarter inventory management.
Built for Modpacks
Encumbrance automatically supports:
Vanilla items and blocks
Custom modded items
Full config editing
Decimal weight values
Example entries:
minecraft:stone = 2.0
minecraft:feather = 0.1
modid:steel_ingot = 1.8
If a mod adds new items, just assign them a weight and you're done.
