Weighted Armors
by ReversTeam
Weighted Armors adds a weight system that sorts armor pieces into light, medium and heavy classes, changing how fast a player moves and falls.
What it does
Each armor piece belongs to a weight class. Iron and netherite armor count as heavy, diamond as medium, and gold, chainmail and leather as light. Wearing heavier armor slows the player and makes falls faster, while light armor gives a small speed boost. By default, each heavy piece worn applies a -5% speed penalty, each medium piece -10%, and light pieces add +5% or +10% speed.
The system can be set to judge the whole outfit instead of each piece: the weight is then taken from the heaviest piece being worn. Gravity effects, meaning the change to falling speed, can be adjusted in the config or turned off completely. The weight data is configurable and data-driven, so server owners can change which items fall into which class without editing code.
Weighted Armors is a Forge mod for 1.20.1 and is published under the MIT License. It is not open source. Every player and the server need a copy of the mod.
Key features
Three weight classes
Armor is sorted into light, medium and heavy classes, each with its own movement effect.
Per-piece or heaviest-piece mode
Speed effects can count each worn piece separately or follow the heaviest piece worn.
Adjustable gravity effects
The change to falling speed can be tuned in the config or disabled entirely.
Data-driven weights
Which armor belongs to which class is set in configurable data, not fixed in code.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Survival and roleplay servers
Server owners who want armor to carry a cost in movement can use the weight classes to shape how players dress for travel and combat.
Custom armor packs
Armor from other mods can be placed into a weight class through the data files, so modded sets follow the same rules.
Who it’s for: Server owners and modpack authors who want armor to affect movement. Players on a server need the mod too, since it runs on client and server.
How it compares
Armor Impact Sounds is a Forge mod for 1.20.1, server-side only and not open source, so it adds sounds without changing movement. Weighted Inventory is open source under the MIT License and covers Forge and NeoForge for 1.20.1 – 26.1.2, with a weight system for items rather than armor. Andrej is also an MIT-licensed open source Forge mod for 1.20.1, but it is client and server, and it does not target armor weight.
