PressureMod
by lightcan
PressureMod adds a blood pressure survival system to Forge, where the player's height, the dimension and the armor worn set the pressure that applies to them.
What it does
The mod tracks a player parameter called TC Tick Pressure, which changes over time depending on the player's Y level, altitude depth, ambient temperature, current dimension and the total armor protection the player wears. Rain or snow falling on a player without a helmet also counts. Two pressure modes are available: a simple one with a plainly stated system, and an experimental mode with a more complex dynamic model. The selected mode is chosen in the configuration.
Effects scale with the value. Between Y 45 and Y 10, a player with armor protection 5 receives Weakness and Confusion. Deeper, from Y 9 to Y -30, Weakness II, Confusion and Wither are applied, and below Y -56 the list grows to include Blindness and Poison. Armor protection of 10 or more lowers the effects, and a value too low brings negative effects. A Sphygmomanometer item displays the current reading for a player. Installation needs only Forge for Minecraft 1.20.1, and the mod runs on the client and the server, so both sides need it. Files are published for 1.20.1 only, and the latest file is 1.1.0-beta, released on 2026-02-01 on the beta channel.
