Light Up!

Light Up (Fabric server-side)

Light Up places light sources automatically around players to brighten caves or surfaces, with per-tick pacing and undo support.

Features

- Server-side only (no client mod required) - Command-driven lighting with range, min light, skylight toggle, and type (surface/cave/all) - Per-player undo of the last lighting task - Action-bar style progress (toggle/format configurable) - JSON configuration with live reload - Multi-version builds (1.19.x → 1.21.x)

Commands

- `/lightup reload` – reloads `config/light-up.json` - `/lightup cancel` – cancels your active lighting task - `/lightup undo` – undoes your last lighting task - `/lightup <block> <min_light_level 0–15> <range> <include_skylight true|false> <lightup_type surface|cave|all>` – starts a new lighting task - Alias: `/lu`

Configuration (JSON)

A JSON file is created on first run:

``` /config/light-up.json ```

Version support

- 1.19.x, 1.20.x, 1.21.x
