Help in improving the code

Hello this is a script from Jailbreak train platform system? - #35 by Kord_K
Problem
The problem is that the code will only work if the part is called “RaftTop”
But what I want instead of making all parts name “RaftTop” I want it to work in models.

Script This script allows player to jump and walk in a moving Cframe platform.
local Players = game:GetService(“Players”)
local player = game.Players.LocalPlayer
local RunService = game:GetService(‘RunService’)

local LastTrainCFrame

local Function
local Function2

Function = RunService.Heartbeat:Connect(function()

--------------------------------------------------------------- CHECK PLATFORM BELOW

local RootPart = player.Character.LowerTorso

local Ignore = player.Character

local ray = Ray.new(RootPart.CFrame.p,Vector3.new(0,-50,0))

local Hit, Position, Normal, Material = workspace:FindPartOnRay(ray,Ignore)

if Hit and Hit.Name == “RaftTop” then – Change “RaftTop” to whatever the moving part’s name is

--------------------------------------------------------------- MOVE PLAYER TO NEW POSITON FROM OLD POSITION

local Train = Hit
if LastTrainCFrame == nil then – If no LastTrainCFrame exists, make one!
LastTrainCFrame = Train.CFrame – This is updated later.
end
local TrainCF = Train.CFrame

local Rel = TrainCF * LastTrainCFrame:inverse()

LastTrainCFrame = Train.CFrame – Updated here.

RootPart.CFrame = Rel * RootPart.CFrame – Set the player’s CFrame
–print(“set”)

else
LastTrainCFrame = nil – Clear the value when the player gets off.

end

Function2 = player.Character.Humanoid.Died:Connect(function()
Function:Disconnect() – Stop memory leaks
Function2:Disconnect() – Stop memory leaks
end)

end)

A simple solution would be to name all of the parts in the model a specific name and then keep Hit.Name the same.

You can also create a table with all of the parts and check if Hit is one of the parts in the table.

I have a plane model which has stuff like interior and exterior model inside and etc. can I make it so it find every parts and union inside the plane model?
