DeepSea

DeepSea is a Fabric mod that adds configurable boat behavior in ocean biomes. All loaded boats are periodically checked every 100 ticks (5 seconds ) by default, and those in the configured ocean biomes (#deepsea:ocean) and tagged with #deepsea:boat will be broken and dropped.

Compatibility

By default, only #c:boats is included in the #deepsea:boat tag and #c:is_ocean in the #deepsea:ocean.

Installation

  1. Drop the DeepSea .jar into your mods folder.
  2. Start the server or load into a world — the mod is active immediately.

This is a server-side only mod. Clients do not need to install it.

Customization

To include/remove boats just create a datapack for the tag file:

data/deepsea/tags/entity_type/boat.json

{
  "values": [
    "#c:boats"
  ]
}

To include/remove biomes just create a datapack for the tag file:

data/deepsea/tags/worldgen/biome/ocean.json

{
  "values": [
    {
      "id": "#c:is_ocean",
      "required": false
    }
  ]
}
