Hydrostatic Pressure

Hydrostatic brings configurable depth* hazardous zones and immersive to Minecraft. Created mainly for modpacks, it adds to the basic underwater mechanics by bringing to the game dynamic pressure zones, low-pass audio dampening, depth hallucinations, and seamless modded gear integration.

*While originally created for worlds with deep oceans, it can be easily configured for vanilla minecraft worlds.

Key Features

• Dynamic Pressure Zones: Configure custom depth boundaries (Y-level based) where environmental pressure begins taking effect. Define specific damage scaling, minimum thresholds, and custom damage sources.
• Configurable Atmospheric Fog & Vision: Independent client-side controls for dynamic underwater fog that scales with depth.
• Decompression Sickness: Ascending too quickly from extreme depths inflicts adverse effects if ascending speed is not properly managed.
• Suit & Gear Degradation*: Environmental pressure slowly degrades armor. 

*Only gear explicitly rated for depth zones takes degradation damage, leaving standard items untouched.

Client-Side Audio

• Low-Pass Filter Muffling: Sound pitch and volume gradually dampen as you dive deeper into ocean trenches.
• Sound Hallucinations: Unprotected divers in extreme depths may experience audio hallucinations—hearing mob sounds echoing through the dark.

Modpack & Compatibility Features

• Mobs & Items: Assign depth immunity to custom entities or water mounts/vehicles, using item/entity tags on the desired zone line in the server config file (Ex.:"zone3 = mod_id:entity_id, ... or mod_id:item_id").
• Biome/Dimension Control: Enable pressure globally across all biomes and/or dimensions, or restrict to specific biomes, using whitelists and blacklists (ocean biomes by default).
• Dependencies: No dependencies at this time.
• Compatibilities: Most if not all mods should be compatible (including Create: Deep Sea submarine sub-level).

For easy configuration of the mod main settings, two config files are generated in the config folder:

1. deeppressure-server.toml: Stores game-logic settings for Pressure Zones, Entity/Item zone rating, and biome/dimension whitelists and blacklists.

2. deeppressure-client.toml: Stores client-side visual and audio preferences for Audio Muffling, Halucination (false) Sounds and fog depth settings.
