The Variadic Arguement Symbol is very useful, it allows you to input multiple different things into a functions arguments. The print function uses this, if you look at the print function in the core functions section on the wiki you will see something like this:

Code:

print(...)

The variadic arguement symbol is represented by three dots. Though simple it is very useful, say you wanted to display and concatenate multiple different strings. You can do such a thing with this symbol, though you can does not mean I am going to go over it. We will just be seeing basic uses of this symbol. Here are a few functions created with that symbol.

Code:

function printargs(...)
print(...)
end

printargs("f",2,3)

Prints:

>> f
>> 2
>> 3

The code above is basically the print function, it allows you to print multiple different things. Here is another example of the use of the variadic argument symbol(NOTE: This is more advanced(:

Code:

function kill(...)
local targets = {...}

for i,v in pairs(targets) do
   if string.lower(v) == string.lower(game.Players:FindFirstChild(v).Name) then
   game.Players:FindFirstChild(v).Character:BreakJoints()
   end
end

end



kill("Riderj")

This will kill anyone specified in the function when you call the function. I could put any amount of strings,numbers,bools, or variables inside the function. The variadic argument allows me to do such a thing. Without it I would have to state the amount of arguments individually. This is very useful for scripts that receive more than one data type.


That is all I have for you guys, if you need me to revise this and make it more comprehensible I will.

wow, I knew what the '...' was before this but I didn't know the term for it! gj!

Haha thanks :D

sometimes with my arguments I make them optional. :3 eg:

root(num,r)
r = r or 2
return num^(1/r)
end
