For example when you make a U shape tube with different heights in each column one side rises and the other falls until they have the same depth. While it is correct in its final state, it is wrong in how it gets there. You have the water slowly come to equilibrium. However in real life, one column of water would fall fast, the other would rise fast, and they'd OVERSHOOT the equilibrium position, but not by as much as when they started. It would "slosh" back and forth like this, with an ever decreasing amplitude until it finally reached equilibrium. THAT is how it actually works in real life. Please make that correction to your implementation.
Yay! You're back! Finally someone who suggests stuff that hasn't been rejected countless times! :D
Well, it is a relatively new function, so any modification now will not have much of an effect on saves that use that function so I doubt that it will break saves. I guess you'll have to wait fora developer to respond and decide whether or not it can be coded in.
Actually, I love this idea. I have been meaning to make a creation that works with water equalization but haven't gotten to it. Your idea would actually make what I have been wanting to create work a lot better and more realistically.
