What is this?

This is an asset with component (BuoyancyComponent) that allows target gameobjects to floating

Effects that are implemented

Pushing out
Lift when moving
Controlled drift on turn
Wave rolling and stabilization

Also drag forces:

• Air drag force
• Viscous fluid resistance

Requirements

• Unity engine 2018.4.0 and older
• Water function that allow to find distance between any point and water surface
• Low polygonal mesh for gameobjects for which you want allow to floating

Project was started as diploma bachelor's work (Russian language). Find the work here
