PeakSurge

PeakSurge is a server-side Fabric mod for Minecraft that gives you precise control over the generation frequency of the minecraft:stony_peaks biome in the Overworld. Whether you want a world dominated by towering peaks or prefer them to be a rare sight, PeakSurge allows you to tune the landscape to your preference.

Features

Configurable Stony Peaks Frequency

Adjust the generation rate of stony_peaks from 1% to 100% (vanilla is 10%). This setting directly influences how often this majestic biome appears in newly generated chunks.

Biome Conversion Options

PeakSurge can optionally convert other mountain-related biomes into stony_peaks as the frequency increases. This includes:

• Cold Peaks: Jagged Peaks, Frozen Peaks (converted from frequency 10% up to 60%)
• Mountain Slopes: Snowy Slopes, Grove, Windswept Hills, Windswept Gravelly Hills, Windswept Forest (converted from frequency 45% up to 100%)
• Highland Meadows: Meadow, Cherry Grove (converted from frequency 80% up to 100%)

Server-Side Only

This mod is designed to run exclusively on the server. Vanilla clients can connect and play without needing to install PeakSurge themselves, making it ideal for dedicated servers.

Live Configuration

Adjust settings on a running server without restarts using the /peaksurge command. Changes apply immediately to newly generated chunks.

Optional Client-Side UI

For single-player or client-side configuration, PeakSurge supports Mod Menu and Cloth Config, providing an intuitive in-game settings screen.

Version Scheme

PeakSurge follows Semantic Versioning + build metadata in the format MAJOR.MINOR.PATCH+mc<minecraft_version>. The version number is always maintained in gradle.properties (mod_version), and fabric.mod.json reads it automatically via ${version} — it is never hardcoded.

Only one position is incremented per release, matching the biggest change in that release. If a release contains both bug fixes and new features, only MINOR is incremented — a new feature always outranks a bug fix.

Technical Details

Note: The mod works by reassigning climate parameter slots to stony_peaks based on a stable hash of each climate volume. When the frequency is below the vanilla 10%, the mod works in reverse and thins stony_peaks out by remapping them back to jagged_peaks.

How it Works

PeakSurge uses a mixin to intercept the Overworld biome generation process. It reassigns climate parameter slots to stony_peaks based on a stable hash of each climate volume and the configured frequency. The Overworld biome table can be rebuilt in place, allowing changes to take effect immediately for new chunk generation without requiring a server restart.

This mod — and this description — was made entirely with AI assistance, in Thailand. Everything you see here is AI-generated. Is the mod good? Yes, I think so. But if you have a problem with people using AI to make mods, that is your problem, not mine. Don't believe this summary was written by AI? That is also your problem.

Future Plans

I might add features, fixes, or other things in the future — things that neither you nor I know about yet. Confused why I am telling you this? Because I might think of a feature at any moment. That is all.
