Aeronautics: Massbound
Adds dynamic mass to items, inventories, and entities for physics-based Minecraft mods.
⬇ Download on ModrinthMassbound is a lightweight mass system designed to make Minecraft physics more dynamic and consistent.
The mod assigns mass to items and vanilla entities and takes inventory contents into account when calculating their total mass. Containers and other inventory-holding blocks dynamically change their mass depending on what is stored inside them, while entities can become heavier based on the items they carry.
Massbound is designed as a general-purpose system rather than an addon tied to a specific vehicle, submarine, or gameplay concept, making it useful for physics-focused modpacks and other mods that need meaningful, dynamic mass values.
Features:
Mass values for vanilla items Mass values for vanilla entities Entity inventory weight Dynamic mass for blocks and containers with inventories Automatic recalculation when inventory contents change Support for modded inventories Designed for integration with physics-based mods
