Rolling Down in the Deep is a lightweight,
fully clientside addon for Do a Barrel Roll
that extends its unlocked camera features to underwater environments.
It redesigns swimming to be more interesting and satisfying by
giving players full pitch, yaw and roll control.

Controls

The default controls are as follows, but can be modified:

  • Mouse x axis to roll
  • Mouse y axis to pitch
  • strafe keys (normally A and D) to yaw and strafe at the same time

Configuration

The mod can be configured in-game using ModMenu and YACL.
Once you install both of these,
you can access the config screen by finding the mod in the mods list and pressing the config button.

Everything this mod does is designed to be as configurable as possible,
so you'll be able to tweak things to your hearts content.
If you think a particular option is missing
you should definitely open an issue on GitHub or message us on Discord,
it will most likely be added.

Disclaimer

This mod modifies swimming mechanics significantly,
which includes allowing players to stay in "swim mode" without moving.
It does this by tricking the server and desyncing with it in a controlled way.
While this works perfectly fine on vanilla servers, and likely will on many others,
some serverside anticheat might flag it as suspicious.

Use at your own risk, and when in doubt, check with your server admin.

Frequently Asked Questions

Does Rolling Down in the Deep need to be installed on the Minecraft server?

No. Modrinth marks Rolling Down in the Deep as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Rolling Down in the Deep require?

Use a file for fabric, neoforge and your exact Minecraft version. Supported versions include 1.21.1, 1.21, 1.20.6. Files for different loaders are not interchangeable.

Rolling Down in the Deep is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
