Water Propeller
by ppercree
Water Propeller is a server-required datapack that changes how fast players move through water, and it adds a boost that applies only while submerged.
What it does
Water Propeller is a data pack, so it needs no loader-specific code to run. Its boost raises speed in water, and the effect is limited to the moments a player is underwater. The author notes that earlier releases could cause villagers to die, and that the datapack can add lag on weaker devices. Server operators who want to see how it works can place a few repeating command blocks running the effect clear command.
Key features
Faster swimming
A datapack boost raises movement speed for players moving through water, so travel across lakes and oceans takes less time.
Underwater-only boost
The speed effect applies only while a player is under water, and it does not change speed on land or in the air.
Lag on weaker devices
The author warns that the datapack can cause lag on weaker devices, so server owners should test it before use.
