How do I find all of the parts in a model with the same Y value?

I want to union all of the parts with the same Y axis and have a certain value (Weight) in a model, but i'm not sure how to do it

local Print = workspace.GameValues.MagicDebug

local roundDecimals = function(num, places) 
--This Part Works (You don't need to see it and it's just a visual thing)
end

if Print then print(script.Parent.Name.."'s Union Function Begin") end
for i, part in pairs(script.Parent:GetChildren()) do
    if part:WaitForChild("Weight") then
        part.Name = roundDecimals(part.Position.Y, 2)
    end
end
if Print then print(script.Parent.Name.."'s Union Function End") end

(It does name the parts their Y but it's more exact if I were to check their Y property)

I created this function for you.. it's pretty straightforward and basically just creates a dictionary with all the different positions inside the model with a table inside of each value naming all the parts.

function findAllPartsWithY(MODEL) 
    local t = {} -- create an empy table

    local function roundDecimals(num, places) -- simple rounding function
        return tonumber(string.format("%." .. (places or 0) .. "f", num))
    end

    for i,v in pairs(MODEL:GetChildren()) do
        if v:FindFirstChild("Weight") then
            local y = roundDecimals(v.Position.Y, 2)
            t[tostring(y)] = {}
        end
    end
    for i,v in pairs(MODEL:GetChildren()) do
        if v:FindFirstChild("Weight") then
            local y = roundDecimals(v.Position.Y, 2)
            if t[tostring(y)] then
                table.insert(t[tostring(y)], v.Name)
            end
        end
    end

    return t
end

findPartsWithSameY(MODEL) -- replace MODEL with whatever model you're using this on

Would there be a way for me to union the parts with the same Y together? I also get an error on line 8 and 26 of your script saying` attempt to call a nil value` ArvidSilverlock 50 — 4y

You need to replace MODEL inside the parenthesis with wherever your model is located in the game. In your case it would probably be script.Parent Wiscript 622 — 4y
