1. Heat Mechanics & Difficulty Modes

Heat sources emit thermal energy to neighboring blocks within a defined radius. Heat accumulates over time during simulation ticks and dissipates when heat sources are removed.

Multi-Difficulty Modes (easy / normal / hard)

Administrators can switch the thermodynamics difficulty dynamically using /bf:fire difficulty <easy|normal|hard>:

• Easy (easy): 0.6x heat multiplier. Only major heat sources (Lava, Fire) operate; furnaces and smokers emit no ambient heat.
• Normal (normal - Default): 1.0x baseline physics. Lava, Fire, Campfires, and active Furnaces emit heat.
• Hard (hard): 1.4x heat multiplier. Torches, Soul Torches, Lanterns, Candles, and Lit Redstone Lamps become active heat sources! Under sustained exposure in hard mode, a torch placed adjacent to wooden planks, wool, or leaves will heat up and ignite the wood into flames.
