[Solved]Assign argument variables in function parameter?

[zutokaza]

How would I do something like this?

Code ( lua) Select Expand

function test(a = 5, b = "hey", c = true)
  if a == 5 then
    print("Letter A is",a)
  end
end

test()

I know it can be done like this:

Code ( lua) Select Expand

function test(a, b, c)
a = 5
b = "hey"
c = true
  if a == 5 then
    print("Letter A is",a)
  end
end

test()

function test(a, b, c)
  if a == 5 then
    print("letter A is " .. a)
    -- You can even modify your variables from there
  end
  return a, b, c
end
 
test(5, "hey", true)


The arguments should be when you call that function, not when you define it.
Of course, "return a, b, c" is optionnal, it's only when you want to store a, b or / and c in a variable, but since the function is called "test", you might wanna return some result somewhere else

Yes, I know of that method too. I want to know if it is possible to do like the surface create function. I would like to assign variables in a table for easier reading.

Code ( lua) Select Expand

sol.text_surface.create({ -- name a local variable something and assign it to the sol.text_surface
      font = "minecraftia", -- font name
      text = "what", -- text you want to show
      font_size = 50, -- font size obviously
      horizontal_alignment = "center", -- default "left"
      vertical_alignment = "bottom", -- default "middle"
      rendering_mode = "antialiasing", -- "solid" (faster) and default
      color = {0,0,0}, -- color must be in a table RGB (http://www.rapidtables.com/web/color/RGB_Color.htm)
    })

In that case you simply make a function that takes a table for the first parameter:

Code (lua) Select Expand

function test(info)
    if info.a == 5 then
        print("Letter A is",info.a)
    end
end

test{a=5, b="hey", c=true}

Keep in mind that the table passed to the function may not have values defined for every entry in the table. It also might not even be a table that gets passed to the function, so be sure your code handles all the possibilities.

Exactly what I wanted. Thanks again for your assistance!
