Mekanism: Scuba Diving Effect
by bluffcon
Mekanism: Scuba Diving Effect gives a player the scubadivingeffect:swimmer status effect while they are underwater with active scuba gear, for modpack developers to use in other systems.
What it does
The effect is applied to a player who is underwater and carrying an active scuba setup, which is a Mekanism scuba tank whose item data marks it as running. The effect is applied on each player tick, and its duration, amplifier and the chest head item that triggers it can be changed in the server config file. Because the status effect is completely invisible, it does not appear in the inventory HUD and shows no particles.
The mod does nothing by itself. Its purpose is to provide a hook that other mods and datapacks can check. A common use is pairing it with a stamina tweaker mod so that stamina depletion is disabled while a player swims. Modpack developers can also test the effect by placing a repeating command block that checks for it.
The mod requires Mekanism to be installed, since the scuba tank it reacts to comes from that mod, and it is published only for Forge and only for 1.20.1. It runs on client and server, and the MIT License covers the code, which is not open source.

Use cases
Stamina tweaks

Testing in a pack
A repeating command block can check the effect, so developers can confirm it is applied before building on it.
Who it’s for: Modpack developers who want a status effect that other systems can detect when a player is diving with Mekanism scuba gear.
How it compares
Mekanism Enchantable is a Forge option for 1.20.1 – 1.20.6 that is server-side only and open source under the MIT License, so it works without any client install. Mekanism: Advanced Core is a Forge mod for 1.20.1 that both the server and clients run, but it is not open source and is published under All rights reserved. Tinkers' Create Diving Modifiers is also open source under the MIT License and runs on client and server, but it adds modifiers rather than a status effect.
