Vector3 as an argument in function?

eg -

function CreatePart(Name,Size)
	Part = Instance.new("Part",workspace)
	Part.Name = Name
	Part.Size = Vector3.new(Size)
end

Is this how it would work or am I going about it in the wrong way?

You can either have 4 parameters, with 3 of them as the elements of the Vector3 value:

function CreatePart(Name, x, y, z)

With line 4 as:

Part.Size = Vector3.new(x, y, z)

OR

You can have 2 parameters, with one of them the whole Vector3 value itself:

This is what Perci1 means to "supply the Vector3 when [Perci1] call the function."

function CreatePart(Name, Vector3Value)

With line 4 as:

Part.Size = Vector3Value

Option 1

CreatePart(ExampleName, 1, 1, 1)

Option 2

CreatePart(ExampleName, Vector3.new(1, 1, 1))
