Let's say I wanted my lerp to last exactly 2 seconds. How would I do that?
COMMUNITY QUESTION
Is there a way to control the Speed of a lerp?
2 answers
-- Declaration Section
local MaxTime = 2 --Change Value
local Increment = 0.25 --Change Value
for number = 0, MaxTime, Increment do
--Your lerp function goes here along with the number. Here's an ex.
Camera.CFrame = Part1.CFrame:lerp(Part2.CFrame, number)
end

what is the purpose of Increment? Does it effect the speed?

^ Yup, increment is basically the speed

This isn't how this works.

Mind explaining Avigant?

This code wouldn't work, you need to use an easing function. Check my answer for a hint in the right direction, you can apply it to what you're doing. TweenService is also an option.
We need to use an easing function to do this. Here's a collection of useful easing functions for your reference: https://github.com/EmmanuelOga/easing/blob/master/lib/easing.lua

-- For all easing functions:
-- t = elapsed time
-- b = begin
-- c = change == ending - beginning
-- d = duration (total time)
local function linear(t, b, c, d)
return c * t / d + b
end
TweenService can abstract this for you should you choose to use it.
Worth noting that Roblox's CFrame:lerp() actually performs slerp (spherical linear interpolation).

https://www.youtube.com/watch?v=ft7t8xHbehM. I used my above code to strictly accomplish this.

So this will work like lerp, or tween?

I don't see what you mean. Your answer wasn't correct, if that's what you're implying.

You could simply use this easing function or TweenService, either way you'd get the same functionality. TweenService just abstracts the act of easing for you so you don't need to worry about it.

I want to know why it wont work because I have been doing using this way for a while and If it is not the way to do so, I would like to change it.

Alpha is a number between 0 and 1, you're not waiting any amount of time between calls, and towards the end of your interpolation the distance covered would be smaller and smaller. You need to ease it.

The only problem with Tween is that it doesn't rotate...

Try using some maths like multiplying, deviding, I've also been tried to make something like this before but never worked.
