Answer 1

how do i get the f table from newpos

If you want to get a table from a function that function needs to return that table.

Let's say you want to create a table that represents a 2d point:

function newpos(x, y)
  local p = {
    x = x,
    y = y,
  }
  return p
end

Then you can do something like

local origin = newpos(0, 0)
print(origin.x, origin.y)
