Buoyancy with Unity Rigidbodies - Part 1 / Planar Buoyancy

[@LostAngel175]

Wow, amazing.I'm currently learning water shader and this make my water more realistic

[@dlgcreations2162]

Simple yet effective! Thanks for some great ideas

[@oscarcerro3816]

Gold, Nothing more to say

[@gamedevinspire]

so much thanks for these tutorials,however i didnt really need it becausei have my own solution but i thank you agian for creating these tuts for more people out there,you deserve more subscribers and views.

[@GrevMivlos]

Very cool - thank you

try this one it works for me

Thank you, the tutorial helped a lot!

I am getting error , any solution...

Is there a link for the project please?

[@munyunu]

Thank you!!!!!!

[@shadaialexander1345]

help, the rigid body just falls right through the plane, are you suppsoed to add something to the plane aka waterR??

[@shadowartz9968]

hey really good tutorials, quick question how would i go about limiting the physics to only work when inside the water plane? because ive noticed that moving the plane up or down doesnt change anything about the simulation.

[@shani1328]

I know this comment if from 5 months ago but just have the water height float be set to the water planes y position. it should be waterHeight = waterPlane.trasform.position.y;

[@beyond-thenoise]

​@@shani1328 what would you do if you want multiple water planes in a scene that have different heights?

[@shani1328]

@@beyond-thenoise Its been a while since I've used / made the buoyancy script, but what I assume you could do is use an array with a for loop for each plane's height.

[@herdboy83]

you should make a link to have the code

[@RavenMinis]

why do you make public floats instead of serializing private floats? Just curious

[@forasago]

faster to type

[@kairu_b]

Noice

[@catsEeter]

how is your sky that color?

[@OnkAnCa64]

Thanks, can you make or do you have an example of a shader made with shader graph on HDRP to manage vertex displacement using a heightmap? thx in advance

[@vincentaindiedev]

Hi, yeah I explain it in the part 2, it should be up in a few days !

[@OnkAnCa64]

@@vincentaindiedev Great, cool :) thanks

[@matus5422]

the object does not float for me :(

[@isaacturpin734]

change "if(difference < 0)" to a different number, for me 1 works.

[@damirshabayev344]

can someone help me my shipS all flip over
