Get second value from function

[Cpt Rawr]

Hi,

I have made a function which returns two values. How can I get the second value from the function and only the second.

In this example below I only want the b value, is this possible or do I have to get both and only use the one i want?

function example()

local a = 1
local b = 2

return a, b

local myA, myB = example()

It's also a common lua idiom to assign throw-away values to a variable named `_`
local _, myB = example()

If you need to get the second and only the second, you can create a throw-away table and index it
funcThatUsesB(({example()})[2])
It's not nearly as pretty as just making a variable though.

depending on how much data you return from a function, at some point you might want to consider returning it as a table instead of multiple returns. I'd say once you hit more than 3 returns it's probably a good idea to use a table instead if you want to return anything else.

There's also the select function which allows you to select single values from a vararg return.

local h = select(2, panel:GetSize())
