PressureMod

PressureMod adds a pressure-based survival mechanic to Minecraft. The system does not aim for medical accuracy, but tries to be as realistic as possible within the limits of gameplay.

The mod affects the player depending on:

• altitude and depth,
• dimension,
• ambient temperature,
• equipment and armor,
• selected pressure physics mode.

Pressure Modes

The mod includes two pressure modes.

Simple Mode (Default)

A simple and easy-to-understand pressure system based on:

• player Y level,
• current dimension,
• total armor protection.

If the armor protection is too low, negative effects are applied.

Important: Pressure does not affect the player if there is open sky above their head.

Realistic Mode (Beta)

An experimental mode with a more complex and dynamic pressure system.

Each player has a parameter called TC (Tick Pressure):

• normal range: 100–120,
• different debuffs are applied outside the normal range,
• a total of 9 pressure stages.

TC changes over time depending on:

• biome temperature,
• depth,
• dimension,
• temperature of items held in hand,
• weather conditions,
• armor protection level.

The mod also adds a Sphygmomanometer, an item that displays:

• the player’s current TC value,
• the current pressure stage. The crafting recipe can be found on the images page.

Simple Mode: Effects

Overworld

Y ≥ 200 Confusion IV (11 seconds), Wither I every 9 seconds, Poison I every 60 seconds if armor protection < 10

Y 45–10 Weakness I, Confusion I if armor protection < 5

Y 9– -30 Weakness II, Confusion I, Wither I every 9 seconds if armor protection < 8

Y -31– -56 Weakness II, Confusion II, Wither I every 7 seconds if armor protection < 12

Y -56– -64 Weakness IV, Confusion IV, Blindness I, Wither III every 3 seconds if armor protection < 15

Y = -64 Weakness V, Confusion V, Blindness I, Poison I, Wither IV every 2 seconds if armor protection < 15

The Nether

Confusion II, Weakness I, Slowness I if armor protection < 8

The End

Weakness II, Slowness II, Blindness I, Confusion I if armor protection < 12

Protection Tablets (Simple Mode)

Realistic Mode: TC Stages

Weather

Rain or snow without a helmet: +1 TC every 180 seconds.

Sources that Decrease TC

• Torches, campfires, magma blocks, lava
• Hot items held in hand
• Hot biomes
• Depth pressure
• The Nether: -4 TC every 40 seconds if armor protection ≤ 9

Sources that Increase TC

• Ice and snow-related blocks
• Cold biomes
• The End: +4 TC every 40 seconds if armor protection ≤ 9

Cold Dimensions

The End is considered a cold dimension and actively increases TC.

Modpack Compatibility

PressureMod can be safely used in any modpack. It does not require special configuration and is designed to be compatible with both vanilla-style and heavily modded survival gameplay.
