Better Diving

Overhaul of the vanilla diving experience modeled on the game Subnautica.


Note: When posting issues down in the comments please use a spoiler for your crash report. I also set up a GitHub Page where you can post issues.




No automatic sinking.

You swim in the direction you are looking instead of just straight forward. So if you look upwards you will swim upwards.

Swimming at the surface doubles swimspeed bonuses and penalities.

Swimspeed minimum at 1 / 3 of base swimspeed and maximum of 4 / 3 of base swimspeed (depth strider enchantment counts toward the base swimspeed -> increases the limits)



You can dive for 45 seconds with taking one breath of air.

Every level of the Respiration enchantment allows you to stay 15 seconds longer under water (up to +45 seconds).

Every 30 blocks below surface oxygen efficiency is decreased and so you consume more oxygen (the next air block over the player is counted as the surface).


Breaking blocks

Breaking blocks under water works at 100% of normal efficiency.

The Aqua Affinity lets you break blocks 10% faster under water.


New items

There are currently 3 versions of each item. A basic version. An improved version for increased perks. And a reinforced versions with more armor points.


Diving Masks:

Removes the water block overlay when diving. Needed for diving with Oxygen Tanks.

With the improved version you can dive at normal efficiency at depths greater than 30 blocks.


Oxygen Tanks:

Hold oxygen for longer dive sessions. Wearing slightly decreases the players swimspeed.


Wetsuit Leggings:

Wearing wetsuit leggings improve the players breakspeed under water. 



Increase the swimspeed of the player.


Visual changes

Oxygen GUI:

Custom oxygen display.


Fog underwater:

Altered fog while diving.

Diving deeper increases fog density.

During night fog gets more dense and turns darker.




Grows like Kelp up to 14 blocks high. Generates between y=30 and y=44. Used in crafting recipes. Also grows seeds which can be harvested with right click and used for crafting.



Just deco which generates all over the ocean.


Acid Mushroom:

Grows in clusters on the seabed. Can be used for crafting.



Limestone Outcrop:

Breaking it drops Titanium or Copper Ore.



Sandstone Outcrop:

Breaking it drops Silver Ore, Lead or Gold.




A small, versatile one-person submersible capable of sustained high-speed travel over considerable distances.



  • various mobs that live in the ocean
  • tools for easier underwater exploration (seaglide, ...)
  • (changes to fog and lightning underwater and a flashlight)
