Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.21.5 · Fabric⬇ Download for 1.21.4 · Fabric⬇ Download for 1.21–1.21.1 · Fabric⬇ Download for 1.20–1.20.1 · Fabric⬇ Download for 1.19.4 · Fabric⬇ Download for 1.20–1.20.1 · Quilt⬇ Download for 1.19.4 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Archived

JSST has been archived so I can stay focused on a smaller amount of mods for now. It was mainly just a sandbox-y type mod I could add random features for, but would require a rewrite to make it more maintainable in current versions.

⚙️ Jack's Server Side Tweaks v2

Provides a suite of server-side tweaks and survival-friendly tools to the game.

Features

All features can be disabled individually, and are highlighly configurable. For more details, see the the wiki.

🗺️ Map Editor

A player removing, changing and renaming icons on a map in-game.

An in-game map editor, accessible by placing a map in an item frame and right clicking with a feather. You can add, rotate and add labels to a variety of icons, and easily remove them after.

🔤 Banner Writer

A player quickly writing text on banners.

A command to generate text on banners. Works in survival, as long as you have enough banners in your hand.

👻 Concealable Item Frames

A picture of two item frames, one invisible.

Players can now toggle the invisibility of item frames by sneak-right clicking with any invisibility potion. Shows particles when they're empty, so you don't lose them.

🚨 Beacon Enhancement

An example of the remade beacon GUI, supporting a max tier of 6 and custom powers.

Adds the ability to customize the beacon's primary and secondary power set, as well as increasing the maximum level to 6. All features are fully configurable.

🔥 Campfire Timers

Progress percentages above a campfire.

Adds a progress bar above cooking campfire items.

💡 Extra Highlights

Dropped sugarcane being highlighted through blocks.

Hidden logs being shown.

Sugarcane, when held in hand, will now highlight nearby dropped sugarcane items; useful for dense farms.

Players can also sneak-right click with an axe to find logs hidden in leaves.

🫵 Item Nudging

Items moving up and towards the player.

Mined items will now aim towards the player when mined, and will always gain enough height to be picked up from above. Especially useful for Skyblock; you'll notice it pretty quick.

🎄 Sapling Replanting

Saplings replanting themselves.

Sapling items, upon decaying, will now try to replant themselves nearby. They give eachother space and will group together for 2x2 saplings.

❓ Other features

There are also a handful of other features not easily shown:

🛠️ Install & Requirements

Works both in single players worlds, and server-side only. JSST is fine to add to existing worlds, but removing it will cause some custom map decorations and beacon powers to reset.

JSST requires Fabric API and YACL.
