How to scale models properly through script using Attributes?
So anyways
I need to scale models using attributes
which will be a vector3 value
these are the same 2 models with different vector3 values in size for the attribute
how would i properly scale them without using anything else like an iv loop to make them the same size of each part
For example if a model is 10 ,10,10
and another model i want to scale to is 50,50,50
I want the model to become from 10,10,10 to 50,50,50
while still maintaining the scale of all the parts in the model
I tried dividing 50/5 and using the value of 5 to multiply the size of 50,50,50 to every single part
now the problem is that since i do this to every part it ends up becoming bigger
does anyone know how I can get this to work?

Good news for you, Roblox just announced that they will add a new Model:ScaleTo() function 8 days ago from this post.
local size = 10 Model:ScaleTo(size)
However, Roblox hasn't officially released it yet as it is still pending (from this page). Be patient until it goes live.
In the meantime, try this code that I got from this guy. (credits btw)
function ScaleModel(model, xScale, yScale, zScale)
local cf, _ = model:GetBoundingBox()
local origin = cf.Position
local scale = Vector3.new(xScale, yScale, zScale)
for _, obj in pairs(model:GetDescendants()) do
local OriginalSize = obj:GetAttribute("OriginalSize")
if OriginalSize == nil then
if obj:IsA("BasePart") then
obj:GetAttribute("OriginalSize", obj.Size)
elseif obj:IsA("JointInstance") then
obj:GetAttribute("OriginalSize", Vector.zero)
elseif obj:IsA("SpecialMesh") then
obj:GetAttribute("OriginalSize", obj.Scale)
end
OriginalSize = obj:GetAttribute("OriginalSize")
end
local DontScale = obj:GetAttribute("DontScale")
if DontScale == nil then
if obj:IsA("BasePart") or obj:IsA("SpecialMesh") then
obj:SetAttribute("DontScale", false)
DontScale = obj:GetAttribute("DontScale")
elseif obj:IsA("JointInstance") then
DontScale = false
else
DontScale = true
end
end
if DontScale == true then return end
if obj:IsA("BasePart") then
local newSize = OriginalSize * scale
obj.Size = newSize
local distance = (obj.Position - origin)
local rotation = (obj.CFrame - obj.Position)
obj.CFrame = (CFrame.new(origin + distance*scale) * rotation)
elseif obj:IsA("JointInstance") then
local c0NewPos = obj.C0.p*scale
local c0RotX, c0RotY, c0RotZ = obj.C0:ToEulerAnglesXYZ()
local c1NewPos = obj.C1.p*scale
local c1RotX, c1RotY, c1RotZ = obj.C1:ToEulerAnglesXYZ()
obj.C0 = CFrame.new(c0NewPos)*CFrame.Angles(c0RotX, c0RotY, c0RotZ)
obj.C1 = CFrame.new(c1NewPos)*CFrame.Angles(c1RotX, c1RotY, c1RotZ)
elseif obj:IsA("SpecialMesh") then
local newScale = OriginalSize * scale
obj.Scale = newScale
end
end
return model
end
