How to give easing style to part when using .Heartbeat?

[karta333 (pro)]

What I’m trying to achieve is i want to animate part position simillar to how tween service does it but without using tween service. Because my part is inside runservice and it doesn’t really work that well

(My script

local Pet = pet:Clone()
Pet.CanCollide = false
Pet.Anchored = true

local offset = CFrame.new(2, 1, 2)


local connection
local function StartFollow()
	connection = runservice.Heartbeat:Connect(function()
		Pet.CFrame = char.PrimaryPart.CFrame * offset
	end)
end

You can’t tween without using TweenService. Do you want to interpolate?

local Pet = pet:Clone()
Pet.CanCollide = false
Pet.Anchored = true

--\\ Constants

local PET_OFFSET = CFrame.new(2, 1, 2)
local SPEED = 9

--\\ Connections

local connection: RBXScriptConnection do
	connection = runservice.Heartbeat:Connect(function(dt: number)
		local goalCFrame = char:GetPivot() * offset
		Pet.CFrame = Pet.CFrame:Lerp(goalCFrame, math.min(1, dt * SPEED))
	end)
end

This will move the pet closer and closer to the target position over time. The SPEED variable determines how quickly it does that.

A Comprehensive Lerp Module for Smooth Property Interpolation

I decided to write a module for handling linear interpolation, as I find myself needing it pretty frequently. I assume you, the reader, might also benefit from this, so I attached the code. If you don’t know what linear interpolation is, it’s smoothly transitioning from one value to the next. Here’s the syntax Lerp(rbx, prop, target, duration?, callback? easingStyle?, easingDirection? is_relative?) rbx: the object you are targeting. prop: the property you want to smoothly change. target: th…

This is what you’re looking for, I think
