CC: Deep Seas

The mod builds on CC: Tweaked and Create Deep Seas. It adds a Ballast Vent and a Water Thruster that can be read and driven from Lua programs, and it extends the fluid handler methods of the existing blocks. A new method reports whether any hole in a hull faces underwater, and the thruster exposes getThrust, getScaledThrust, getAirflow and getAirflowScaling so a program can read its output.

Peripherals added by the Deep Seas addon expose internal information about submarines, so a computer can monitor a vessel while it sails. Because the mod works alongside the Create Deep Seas addon, it fits modpacks that already use submarines and lets their operators automate depth, ballast and thrust. Files target only 1.21.1 on NeoForge, and the code is published under the MIT License, so it is open source. The mod needs CC: Tweaked and Create Deep Seas to run, and it is classed as client and server, so servers and players both need it.
