This repository contains ready-to-use water code reverse engineered from libpirates.dll.
This source was originally based on the water in a Pirates of the Caribbean cannon ride experience at a theme park. It later was implemented into Pirates of the Caribbean Online as the game's ocean wave calculation system.
This reverse engineering of the code is intended to be used alongside the latest version of the Panda3D Game Engine, which can be obtained here: https://github.com/Panda3D/Panda3D/
This subheading describes how to build libpirates alongside Panda3D.
The following code must be added to makepanda/makepanda.py.
The goal is to build libpirates into the panda3d.core package, thereby allowing this code to be interrogated by Panda and referenced in Python code.
The code below is provided in the order that it will appear in makepanda.py. Search makepanda.py for similar nearby code, then add the code below to the relevant areas.
Upon completion, run makepanda.py to build Panda3d. The built image will have libpirates support. From there, you may simply import SeaPatchNode and SeaPatchRoot from panda3d.core.

This will allow makepanda to discover the files and compile them into core, which can later be used from within your Python panda application.
