GTNH Extra Nerf

GTNH Extra Nerf is a fixed-ruleset difficulty add-on for GregTech: New Horizons on Minecraft 1.7.10. The mod is built for the pinned full GTNH environment.

It just nerfs stuff.

Steam Input Hatches hold 640,000 L to reduce power failures on high-demand recipes.

Supported pack release: GT New Horizons 2.9.0 (see compatibility). Release JARs are published on the GitHub releases page.

Telemetry and team tracking

Telemetry is opt-in and is decided for each world. When a world has no existing choice, an operator (or the owner of a singleplayer world) is shown a window with three choices: disable reporting, send basic statistics, or enable team tracking. An earlier team opt-in or telemetry opt-out is carried over. The console of a dedicated server is told how to answer with extranerftelemetry on or off. No statistics or team reports are sent until someone has answered, and the server never waits for it. Basic statistics include a random ID valid for one server run, the online player count, the highest available world progression tier, singleplayer status and an optional randomized JAR proof, about once per hour. They contribute to community statistics about active servers, online players and world progression, and help understand mod usage. The choice can be changed at any time with /extranerftelemetry on|off and /extranerfteam on|off. See the Privacy & Telemetry Policy and telemetry details and testing.

Team tracking is an alternative reporting mode. Enabling either it or basic statistics turns the other mode off; team reports also contribute to the server statistics. See team tracking. The mod also checks for newer releases (update check).

Build and test

Clone the repository with its GTNHGradle submodule, then run the Gradle checks:

git clone --recurse-submodules https://github.com/kuba6000/GTNH-Extra-Nerf.git
cd GTNH-Extra-Nerf
./gradlew check
./gradlew build

On Windows:

.\gradlew.bat check
.\gradlew.bat build

Run the automated full-pack scenarios with:

python .github/scripts/run_horizon_tests.py

The runner creates a scratch world, writes JSON/JUnit reports and closes its own client after the selected tests finish. The loot-preview and quest-retrieval scenarios use a separate scratch world:

python .github/scripts/run_horizon_tests.py --tests gtnhextranerfquesttests,gtnhextranerfloottests

Build artifacts are written to build/libs. See docs/BUILDING.md for full-pack client/server tasks and toolchain details.

Integrity model

Recipe patches identify exact upstream recipes and require their expected cardinality. Typed audit scopes aggregate successful semantic changes from recipe helpers and audited mixins. In production, a missing, duplicate or rejected patch produces a fatal GTNH Extra Nerf integrity check failed startup error instead of silently running an incomplete balance ruleset to prevent potentially gamebreaking bugs. In a deobfuscated development environment, the same failures are logged as warnings and startup continues so an incomplete local runtime remains usable.
