This is a map plugin which adds an ocean with waves to the game.
Press O to open the menu.
There are tons of options there to play with, more than I can explain, feel free to ask questions.
This is my 250K special.
All the credit for making the physics work go to WNP78!
Before you tell me it's too bouncy when you spawn with a ship, please go watch videos on ships being launched. XD
Also, when the waves are large, starting on an aircraft carrier is probably not going to work.
There is a known issue with looking straight up underwater. Just avoid doing that.
It seems to not be compatible with the Free Cam mod...I can't fix that. Also not compatible with the underwater cam, but you don't need that with this anyway.
There are issues with the weapons. Make all your missiles waterproof true for now!
