How to tween character parts?

[obamagremlin (xvez)]

Is there a better way of doing this like a more modern way (without using animations)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TweenService = game:GetService("TweenService")
local Players = game:GetService("Players")

local localPlayer = Players.LocalPlayer
local character = localPlayer.Character or localPlayer.CharacterAdded:Wait()

local remoteEvents = ReplicatedStorage.RemoteEvents

local WeldManager = {}

local appendigeNames = {
	"Right Arm",
	"Left Arm",
	"Right Leg",
	"Left Leg",
	"Head"
}
local correspondingJointNames = {
	"Right Shoulder",
	"Left Shoulder",
	"Right Hip",
	"Left Hip",
	"Neck"
}

function WeldManager:tweenWeld(targetCharacter: Model, part1: BasePart, startCFrame: CFrame, endCFrame: CFrame, tweenInfo: TweenInfo)
	if targetCharacter == character then
		remoteEvents.ReplicateTweenWeld:FireServer(targetCharacter, part1, startCFrame, endCFrame, tweenInfo.Time, tweenInfo.EasingStyle, tweenInfo.EasingDirection)
	end

	local torso = targetCharacter:FindFirstChild("Torso")

	if not torso then
		return
	end

	local weldExists = false
	local weld

	for index, descendant in ipairs(targetCharacter:GetDescendants()) do
		if descendant:IsA("Weld") then
			if descendant.Part1 == part1 then
				weldExists = true
				weld = descendant
			end
		end
	end
	if not weldExists then
		weld = Instance.new("Weld")
	end

	for index, appendigeName in pairs(appendigeNames) do
		local appendige = targetCharacter[appendigeName]

		if appendige then
			if part1 == appendige then
				local jointName = correspondingJointNames[index]
				local joint = torso[jointName]

				if joint then
					joint.Part1 = nil

					weld.Part0 = torso
					weld.Part1 = part1
					weld.C0 = startCFrame
					weld.Parent = torso
					TweenService:Create(weld, tweenInfo, {C0 = endCFrame}):Play()
				end
			end
		end
	end
end

function WeldManager:resetWelds(targetCharacter: Model)
	if targetCharacter == character then
		remoteEvents.ReplicateResetWelds:FireServer(targetCharacter)
	end

	local torso = targetCharacter:FindFirstChild("Torso")

	if not torso then
		return
	end

	for index, descendant in ipairs(torso:GetDescendants()) do
		if descendant:IsA("Weld") then
			descendant:Destroy()
		end
	end

	for index, jointName in pairs(correspondingJointNames) do
		jointName = correspondingJointNames[index]
		local joint = torso[jointName]

		if joint then
			local appendigeName = appendigeNames[index]
			local appendige = targetCharacter[appendigeName]

			if appendige then
				joint.Part1 = appendige
			end
		end
	end
end

return WeldManager

I don’t see why you would need to tween character parts? It takes so much more effort than animations.

There probably isn’t a modern way except animations.

Okay, I just feel like the problem with animations is that I have like specific time values in my scripts that the animations need to end by, I think I will try using animations.

You can adjust the speed at which your animation runs, or just focus on making your animation actually last the idealized duration
