FirmaNutrition
by JotredDev
FirmaNutrition changes how TerraFirmaCraft tracks player nutrition, replacing summed recent meals with a continuous decay model.
What it does
Under the addon, nutrient levels are read directly from the player and fall over time instead of being recalculated from stored meals. Each nutrient has its own decay rate per player, and the rate can be tuned with a command, so the hunger bar drops gradually rather than in sudden large steps. Nutrition can also be set directly with a command, which lets server owners adjust a player's levels when needed.
Two settings choose how decay runs: either a fixed rate, or a rate that scales with the nutrition a player currently holds. The dynamic option can be given a minimum proportion below which decay stops, so levels never fall past that floor. The addon also lowers the maximum hidden nutrition, which makes reaching an average of 100% nutrition easier. Because TerraFirmaCraft meals do not carry nutrient types, the addon is technically required for the nutrient tracking to work.
FirmaNutrition is server-side only, so players join without installing it. It is open source under the MIT License and targets NeoForge for 1.21.1 with a single file, version 1.1.2. TerraFirmaCraft is a required dependency.
Key features
Continuous nutrient decay
Nutrient levels drop steadily over time, making decay feel more realistic than the stored-meal method.
Per-player decay rates
Each player has individual decay rates for every nutrient, adjustable with a command.
Configurable decay modes
Decay can run at a constant rate or at a rate that follows the player's current nutrition, with an optional floor.
Command-based nutrition control
Server owners can set a player's nutrition directly with a command.
Further additions
The addon extends the TerraFirmaCraft nutrition system with changes that go beyond decay alone.
