This is a simplified change of this workshop item (so credits go there!)

https://www.leadwerks.com/workshopitem?tags=Material&queryType=1&fileType=0&fileid=699303085

A few changes I did:

1) the water.mat:

    changed Diffuse color (64,64,64,64) + refraction shader

2) The script, simplified, like this:

Add this script to a box, cylinder, what you want...With the water material up there added.

And here the result

sorry Footsteps sounds don't matched..
