Timed Lerps Module

Hello all!

Today I have made a module that has timed Linear Interpolation for all properties of the part.

Link : Lerping Module - Roblox

Code 
local RunService = game:GetService("RunService")

local Lerp

Lerp = function(Part : PVInstance, Property : string, Goal, Time : number)
	local TimePassed = 0

	local Start = Part[Property]

	while TimePassed <= Time do
		TimePassed += RunService.Heartbeat:Wait()
		Part[Property] = Start:Lerp(Goal, TimePassed/Time)
	end
end

return Lerp

Example code:

local Lerp = require(script.ModuleScript)

local PartToLerp = workspace[YOURPARTHERE]
local Property = "YOURPROPERTYTOLERP"
local Time = YOURLENGTHOFLERP
local Goal = YOURLERPGOAL

Lerp(PartToLerp, Property , Goal, YOURLENGTHOFLERP)

Position Example Code:

local Lerp = require(script.Lerp)

Lerp(workspace.LerpingPart, "Position" , Vector3.new(48, 34, 34), 3)

Hope you enjoy!

A couple of questions:

  1. Why would we use this when the TweenService let’s us do this in-engine. Which would be much faster than trying to make a Lua variation of it.
#3

Well, as far as I’m aware, lerping is more efficient than tweening for linear interpolation.

#4

You should add tweenInfos for these lerps.

#5

I don’t think lerping is necessarily better than tweening, why do you say it is more efficient? From experience I believe they aren’t as smooth, plus they don’t support easing styles. I could be wrong so just trying to understand, maybe you can provide a comparison?

#6

That’s why I pointed out linear interpolation. Linear interpolation is for when you simply wanna change a value smoothly.

And yes, I’m pretty sure it’s more efficient. I can’t state it as a fact, though.

#7

Btw @Tomroblox54321, can you please put the model out for sale, think it’s still private.

#8

Not all properties have access to a built in Lerp function, so this only works with properties that support it (Color3, Vectors, CFrames, etc)

A lerp function is also, as the name entails - Linear. Which means you have no control over the transition rate

TweenService offers more control and is generally comparable in performance. Reinventing the wheel when it’s supported in-engine is usually bad practice

#9

Use TweenService.GetValue if you want to add customizable easing styles to the module. Instead of a while true loop with a Heartbeat:Wait() just use a heartbeat connection and disconnect it when the time goes over what it should be.

#10

Made it on-sale. Not sure what happened there.

#11

I’ll try to add easingstyles aswell.

#12

Lerps cause less lag and are better since they are based off of math.

#13

I’d use Stepped instead of Heartbeat, but that is a personal choice.

#14

I tried using Stepped for this module instead of heartbeat but it entirely broke it.
