Thermodynamica Mod adds realistic heat transfer mechanics to Minecraft. It runs temperature spreading on separate CPU threads, so complex setups do not slow down your server ticks. The mod acts as a physics framework where block temperatures change based on nearby heat sources, material conductivity, and local biome weather.
Features:
- Calculates heat movement on separate threads so game tick rates stay smooth.
- Lets blocks conduct, transfer, and lose heat based on customizable material settings.
- Adjusts block temperatures naturally according to the surrounding biome climate.
- Runs as a lightweight physics base that reads block values from simple JSON data packs.
- Reloads thermal values in real time whenever data packs change.
- Provides built-in status checks to monitor active heat sources and simulation speed.
Commands:
/thermodynamica status: Checks active heat sources and engine health./thermodynamica tps: Views detailed simulation tick speed profiling.
How to Use:
- Install a compatible heat data pack to define material properties and heat sources.
- Place heat sources near blocks to start spreading temperature across the area.
- Run the status command in chat to monitor simulation activity.
