Heavy Inventories is a mod that aims to give a more realistic feel to Minecraft by adding a configurable weight to the items and blocks in the game, in an immersive, Minecraft-like way.
Version 4.0.0 for NeoForge 1.21.1 is currently in development. We will need help translating this mod to your language! Please help if you can!
PLEASE post any issues or suggestions on the github issue tracker.

Features
- An immersive and realistic experience for more hardcore players.
- Configurable item and block weights.
- Customizable in-game GUI.
Heavy Inventories does not generated weight files any longer. It uses crafting recipes to decide the starting weight of each item. If the item does not have a crafting recipe, it defaults to 0.1 Floating-Point.
This however can be changed in a .json file should you choose to. Example for ./weights/minecraft.json:
{
"cobblestone": {
"weight": 10.0
},
"dirt": {
"weight": 5.0
}
}
This can also be done via in-game commands. While holding the item you want to change the weight of, run command /heavyinventories set weight <number>
We have removed the old "pumping iron" feature, which allowed increasing the players strength through using an anvil.
Using strength potions now increase the players max carry weight to up to 120% of their base carry weight.
We have also introduced the enchantment Bracing which applies to chestplates that will increase the players carry weight to up to 100% (double).
We are implementing an enchantment for leggings which will allow for adding up to 50% extra carry weight.
Currently this mod is in development for NeoForge, but there are plans to include a Forge and Fabric release in the works.
