So, to clarify, you only want to move the part along the y axis? up and down?
I don’t think lerp is the right use case for such a task.

Change that
water.CFrame.Y = water.CFrame:lerp(CFrame.new(water.CFrame.Y, stop.CFrame.Y),i)
to that
water.CFrame = water.CFrame:Lerp(stop.CFrame, i/timelimit)
Because i must be between 0 and 1 inclusive.

opps forgot to add that in, thanks
Yes, I only want the part to move up and down, although it is not a must, as I figured out a way, I simply made an exact copy of water, named it stop, and moved it on the Y axis, that way it will line up properly.

It worked! Thanks!
Only problem is that it moves really blocky like.
I added a video so you know what I mean
It almost looks as if I was setting the CFrame to the same value but 4 studs above the original one very second. I think that is pretty much what is happening, but I wanted to use lerp so it went up smoothly. This is caused by the wait(1) but if I remove it, it just teleports to the top.
I used to use BodyVelocity, but the water just kept going up and I couldn’t really control the time it took to reach the top, so I switched to lerp.
Is there a better way to do this?
Yes, you can increase the amount of iterations
local iterations = 10
for i = 0, timelimit - 1 do
for j = 0, iterations do
water.CFrame = water.CFrame:Lerp(stop.CFrame, (i * iterations + j)/(timelimit * iterations))
wait(1/iterations)
end
end

1 would be 100% in the Lerp function.
Instead of doing this:
for i = 0, timelimit, 1 do -- Time limit is incrementing by 1, or 100%
try using this:
for i = 0, 1, 1/timelimit do -- Time limit is incrementing by 1/70 or ~1.43%

What are iterations? Is it like the ammount of time that code runs?
And what are all the multiplications for?
I want to understand the code so I can replicate it if I encounted the same problem.
Also, the code didn’t quite work, it teleported the water to the stop position.
But thanks anyways, I want to learn how this whole thing works so it would be great if you could explain the code aswell.

Yes, that does work!
But there are two problems.
1-. Water rises extremley slowly
2-. Water still rises in blocks, which ruins the whole effect.
Here is a vid of what I mean
I want the water to reach the top in the time-limit(70 seconds), and I wanted to use lerp so that it goes up seamlessly, without it being blocky.

Then why not use TweenService?
TweenService guarantees smooth transitions.
For instance:
local TS = game:GetService("TweenService")
local Ti = TweenInfo.new(70)
Ts:Create(part to tween, TI, {Position = Desired position}):Play()

Oops, a mistake, try this
local startCFrame = water.CFrame
local iterations = 10
for i = 0, timelimit - 1 do
for j = 0, iterations do
water.CFrame = startCFrame:Lerp(stop.CFrame, (i * iterations + j)/(timelimit * iterations))
wait(1/iterations)
end
end

This is how it looked when I used BodyVelocity, this is what I mean by smooth transitions.
Thing is I don’t want to use BodyVelocity as I cannot control the time it takes for the water to reach point A to point B and also the water doesn’t stop at point B.
My guess is that your best select is tween service.

How could I use TweenService? I did open a wiki article on it a while back for scaling gui using Tween but I just thought it was for GUI and lerp was for objects.
I’ll do more research on Tween, but that sitll leaves me the queston on what lerp is for? I thought lerp was also for smooth transitions.
Lerp is for saving pain on calculations, and can be useful. I’ve edited my post above, hope it helps.

local water = script.Parent.Water
local stop = script.Parent.Stop
local timelimit = 70
local tweenservice = game:GetService("TweenService")
local tweeninfo = TweenInfo.new(timelimit,Enum.EasingStyle.Linear,Enum.EasingDirection.Out)
local goal = {position = stop.Position}
local tween = tweenservice:Create(water,tweeninfo,goal)
wait(5)
tween:Play()

I hope this helps if not let me know! Also it might got spelling mistake as I didn’t test it. So check that.

It did work thank you very much but I think I’ll go for Tween.
Thank you though!
Yup, it worked!
Just had to fix some caps in Ts and Ti.
Thank you very much @VegetationBush and @Mr_Gamerious for the help on tweening!

I would recommend using run service for that and divide deltaTime by the expectedTime variable, before adding(+=) it to alpha value, to await the function to be finished set a bool value and change it, after the alphaValue reaches your set value by doing that
CanPass = alphaValue >= SetMaxValue
And then disconnect the event.
