Custom Waves Using Gerstner Wave Function (read notes very important)

[loltaco1110 (Amateur_Programmer)]

Notes:

• Please submit bug reports by commenting below, thank you.
• I am not using Gerstner Waves (woops), but I am using sin waves. (Sorry will fix soomTM) - Maybe fixed
• Working on foam.
• Thinking of creating some sort of code where it unloads bones the farther away they are - For performance & looks reasons.

I would like to share my work on creating custom waves, so you do not have to take 2 days to figure these out. Also, I will explain how I made it. (magic)

Video of my creation:

How I made it:
I found information on how to do this just by looking up key words. I eventually came to this devForum page:

Making A Mesh Deformation Ocean

If you stumbled upon this, more likely than not, you want to create a deformable mesh ocean like a lot of these cutting edge games nowadays. Good news is that after days of my own searching an learning to no avail, I eventually figured it out and now I’ll share what my process was. Note: This tutorial only covers the setup, the mesh, and the basics to scripting the waves. If you want an in depth tutorial on the wave equation and scripting side of things, use this well written post. This is my …

That only told me how to make the mesh with bones, so I had to code it myself.

Coding Adventure: Gerstner Waves

Explained everything I needed to know after a couple rewatches.
I just played around with different combinations of math functions and code until I got what I currently have. Anyways, enjoy having custom waves without the hassle!

Change log:
9/22/23

1. Changed some logic - maybe it’s using the gerstner wave function now?
2. Added a tag (“wave_drift”) that can be used to makes objects float in the water.
3. Added code to make objects float in the water.

8/31/23

1. Added displacement in the x and z direction.
2. Added 2 more textures.
3. Changed the way textures are animated for a more realistic look.

thanks for making this! was looking for solutions to gerstner waves on ROBLOX for a long time, and I’ll have a mess around with your model now

Great contribution!

Also…

Find the Y value in a X,Z position?

[loltaco1110 (Amateur_Programmer)]

Could you explain further on what you mean by that?

[Arro_x]

Oh, sorry.

Say I have any given object. Using its X and Z position values, how can I determine the Y value that corresponds to its position in the water?

[loltaco1110 (Amateur_Programmer)]

I just added up the x and z results in the script, note the current model does not use the gerstner wave function (woops) but I am working on it.

how optimized is this? just wondering

[loltaco1110 (Amateur_Programmer)]

Optimized enough to run easily on my phone.
