Ocean

Sailing the ocean in your vessel is a safe enough venture, until you come across a pirate! Other players and random NPC ships (through VOTS only) may try sending you to a watery grave. Should you plunge into the cold blue, don't linger for long! Hungry sea creatures will seek you out after a short time. Keep this in mind when exploring underwater structures.

In Isles of Alex, the ocean floor tends to sit at around 50 blocks deep and contains no lava pools or caves by default.

Tidal Towns

The popular datapack, Tidal Towns, can be made compatible with Terra worlds by making a few minor adjustments. Namely, you must change the vanilla biome specification to check for structures instead. Specifically, you can set "biomes": "#minecraft:has_structure/ocean_ruin_warm", in its data/joshie/worldgen/structure/village_ocean.json folder for compatibility with Isles of Alex.

We found it best to also reduce generation frequency by setting "spacing": 136, "separation": 32 in its .../structure_set/village_ocean.json file. You can use this tool to visualize how spacing/separation values look before installation in your server's world/datapacks folder. Note that generation will occur in all worlds; Mojang has not provided a way to apply datapacks to specific worlds (to our knowledge).

The Surveyor compass will not detect or point to villages generated by Tidal Towns.
