RealWeight
by Atomization
RealWeight gives players and their inventories a weight that slows movement and affects how much they can carry on NeoForge for 1.21.1.
What it does
Weight is applied to the player, so the heavier a load becomes, the more it hinders movement. The weight of an item depends on its armor, appearance, material and other factors, and a block's weight depends on its density under given conditions. Players do not gain physical strength from levelling up, since that is planned for future updates rather than present in the mod. Client and server both need it, and the mod is released under All rights reserved, so it is not open source. Its optional dependencies are Create and Create Aeronautics.
Key features
Weighted player movement
Carried weight produces real penalties on movement, so a heavy load changes how the player moves through the world.
Item and block weights
Items take weight from armor, appearance, material and similar factors, while blocks take weight from their density.
Compatible with Create Aeronautics
The mod is customizable and works with Create Aeronautics and Legendary Survival Overhaul.
