Hello, I can't get this to work, I am trying to make (the red part) find the order of the track parts(Orange Part) and Cframe through them in Order. This is for a rollercoaster so it would be able cframe through each part.

Thanks!

Code:

local function StartCoaster(Coaster,RailModel)
    local Rails = RailModel:GetChildren()
    --sort rails table from lowest number name to highest number name:
    table.sort(Rails,function(a,b)
        return tonumber(a.Name) < tonumber(b.Name)
    end)
    for RailNum,Rail in pairs(Rails) do --go through ordered rails
        for _,Segment in pairs(Coaster:GetChildren()) do
            local GoalRail = Rails[RailNum + tonumber(Segment.Name)]
           local Tween = game:GetService("TweenService"):Create(Segment, GoalRail.CFrame)
           Tween:Play()(Segment, GoalRail.CFrame) --handle tweening here
        end
        wait(1) --change to time taken for tween
    end
end



StartCoaster(workspace.Coaster, workspace.RailParts)
