Argument and Parameter

What is the difference(s) between “argument” and “parameter”

#2

A parameter is like a variable or placeholder you use to define that a value needs to be passed

 local function f(parameter)
 end
 -- you can pass any value to the function, the passed value
 -- will be the argument you supplied

Okay, I have a question

workspace.part.CFrame = workspace.part2.CFrame.LookVector*2

11:54:40.044 - Workspace.Script:1: bad argument #3 (CFrame expected, got Vector3)

It says 3rd argument was badly used. What are the 1st, 2nd and 3rd arguments?

#4

You meant to do something like

 local C = workspace.part.CFrame
 workspace.part.CFrame = CFrame.new(C.LookVector*2)

A LookVector is a Vector3, not a CFrame.

#5

Actually I know the mistake I did and I know how to solve it. I want you to find the arguments.

#6

Here the argument you passed was the Vector3, by doing part.CFrame = ...
you’re basically overwriting its current CFrame property.

#7

Well okay. What were the 1st, 2nd arguments?

#8

The error is related to instances being userdata with metatables and metamethods within, the error was thrown because the third argument for __newindex, the Vector3 you passed cannot be used as a CFrame directly.

In your case as you’re using it, there’s only one argument which is the Vector3.
