About Underwater

From Thunderstore

Allow players to go underwater.

Adds an option for players to walk along the seafloor instead of swimming at the water surface. This option can be changed in the mod config or by pressing the Backspace key in game (key can be changed in config).

This mod was created primarily to assist with placing building pieces underwater. I may try to add diving controls in the future, but for now the options are to swim on the surface or walk on the bottom.

Run the game once with the mod enabled to generate the config. See config for details on what each option does.

This is primarily a client side mod. It may also be installed on a server to sync configurations. A server may optionally require that clients have the mod installed via the ConditionalConfigSync.ModRequirements.cfg file in the ConditionalConfigSync config directory.

Some configuration options can be enforced by a server running ConditionalConfigSync. See included ConfigSync_Readme.txt file for more information.

Installation

This mod uses BepInExPack Valheim as a mod loader. You can use any BepinEx compatible mod manager to install the mod, or manually place it in the BepixEx plugins directory.
