Background moving train

[ciaraparlay (vamp)]

@Dev_Scriptone

local TS = game:GetService("TweenService") 
local TI = TweenInfo.new(10, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut)
local Train = workspace.Train
TS:Create(train.PrimaryPart, TI, {Position = Vector3.new(ending position));

Just so you know, doing this will not work, because setting the primary part’s position only changes the primary part’s position.

You should to use this method (albeit outdated), because it would take significantly longer to rig the train.

@Edison20020216, here’s some food for thought.

local TweenService = game:GetService("TweenService")

local CFrameValue = Instance.new("CFrameValue")
CFrameValue.Value = Train:GetPrimaryPartCFrame()

local tween = TweenService:CreateTween(CFrameValue, TweenInfo.new(10, Enum.EasingStyle.Linear), {Value = endCFrame}) -- make sure to define endCFrame

CFrameValue.Changed:Connect(function()
	Train:SetPrimaryPartCFrame(CFrameValue.Value)
end)

tween:Play()

tween.Completed:Wait()
CFrameValue:Destroy() -- does garbage collection for changed on destroy

If you don’t feel comfortable using this method, then you can use the more updated version of @PostApproval’s model tweening method:

Introduction to Tweening Models

Edit (06/30/2021): Due to the release of the new pivot APIs and the thankful deprecation of SetPrimaryPartCFrame, the legacy method of CFraming is now also appropriate and you do not necessarily need to use this welding method. Do note that the pivot CFrame is different from the PrimaryPart CFrame though, so you will have to account for that when writing your proxy objects. Edit (05/31/2023): Roblox has an official code sample for model tweening! It’s very lightweight and covers the necessities…
