Buoys
by rotgruengelb
Buoys lets players place dyeable buoy blocks directly inside water, where they can be linked into lines across open water.
What it does
Buoy blocks can be placed straight into water without needing a supporting block underneath. Each one can be dyed, so a row of buoys can match a builder's colour scheme. Buoys are built as a double-height block, and the top half leaves room for lanterns, torches and similar items to sit on it. The double block is shorter and smaller than a full-height block, which keeps the marked water from looking cluttered.
When a buoy is placed, it connects to other buoy blocks nearby, both straight and diagonally, forming a chain. Placing a block one level above a buoy stops that buoy from connecting to others, and a block placed in that position is broken again once the buoy is set down. Buoys is published for Fabric and Quilt for 1.21.1, with 1.21 also among the game versions that have files, and it requires Fabric API on both loaders. The code is open source under the MIT License.
Key features
Dyeable buoy blocks
Buoy blocks take dye, so a line of markers can be coloured to match a route or a harbour.
Water placement
Buoys can be placed directly inside water and do not need a block beneath them to stay in place.
Double-height design
The top half of each buoy holds lanterns, torches and other small items, while the block stays shorter than a full-height block.
Automatic chaining
Buoys connect to nearby buoys on placement, straight and diagonally, so a run of markers forms in one action.
Connection blocking
A block placed one level above a buoy prevents it from linking to other buoys, which gives builders control over where chains stop.

Use cases
Marking water routes
Chains of buoys can outline a channel, a dock approach or a shipping lane across open water.
Decorating harbours
Dyed buoys with lanterns on top can light and colour a waterfront without extra support blocks.
Who it’s for: Builders who mark routes or decorate waterfronts, and server owners who want water-based markers in a shared world. Both client and server need the mod, and Fabric API must be installed beside it.
