WPO Hydraulic Utilities

This repository currently targets Forge 1.20.1 on the active branch.

What It Adds

Hydraulic Utilities adds practical control blocks for moving, directing, filtering, sealing, and testing water in WPO setups.

The current block set includes:

• Drain
• Pump
• Nozzle
• Valve
• Water Grate
• Water + Item Grate
• Water + Item + No Mob Grate
• Watertight Door
• Watertight Trapdoor
• Creative Water Source
• Creative Lava Source

System Overview

This add-on is focused on control and infrastructure rather than world simulation.

Its systems let players:

• pull WPO water into internal machine tanks
• push stored water back into the world
• spray or output water through nozzles
• block or allow flow with valves
• filter what passes through a grate
• keep structures sealed with watertight door blocks
• spawn test fluids directly with creative sources

The machine-side tuning is controlled through:

• machine tank capacity in buckets
• drain throughput in WPO water levels
• pump throughput in WPO water levels
• nozzle throughput in WPO water levels
• creative source output in WPO water levels

Configuration

The common config is stored at:

config/wpo_hydraulic_utilities/common.toml

The in-game config screen exposes both system toggles and balance values.

System toggles include:

• drains
• pumps
• nozzles
• creative sources
• valves
• grates
• watertight doors
• watertight trapdoors
• redstone control
• void excess water

How It Fits With WPO

Hydraulic Utilities assumes the base Water Physics Overhaul simulation already exists and adds player-facing tools around it.

This mod is useful for:

• moving water in controlled builds
• automation setups
• compact test rigs
• sealing structures against WPO water
• creative debugging and reproduction setups

For external fluid transport between machines, Pipez is the recommended companion mod.

Build

For local source builds, clone these repositories next to this one so the folder layout is:

../SKDS-Core
../Water-Physics-Overhaul
../WPO-Hydraulic-Utilities

Typical local build:

.\gradlew.bat build

Explicit version build:

.\gradlew.bat build -PmcVersion=1.20.1

Stage the release jar into the workspace release folder:

.\gradlew.bat stageRelease -PmcVersion=1.20.1

Version-specific Minecraft and release values now live in versions/<mcVersion>.properties. Keep release tags in the form v1.20.1-<mod-version>, and branch by Minecraft version when later ports stop being source-compatible.

Version Strategy

• Stable repository name, without the Minecraft version in the repo title
• main for the current maintained line
• mc/<minecraft-version> branches when code starts to diverge between game versions
• release tags in the form v<minecraft-version>-<mod-version>
