so ive been trying to make an ocean and i finally found a way to make gerstner waves but now i wanna add buoyancy but i cant figure out how to add it for items or players boats etc

#

do i need to add a separate script to the object/part it self or do i need to a server side script?

Bouyancy is an upward force exerted on bodies within a fluid. For Gerstner waves, you can simplify bouyancy as a force that counteracts the body's weight when that body's position falls below the wave height at that position

#

You can find several resources for implementing bouyancy in Gerstner waves

I Made Ocean Waves and Buoyancy in Godot

Been playing Sea of Thieves a lot recently and really wanted to make some water physics, so I implemented some Gerstner/Trochoidal waves in Godot with a vertex shader and then simulated buoyancy in GDscript.
