Hello, I am currently trying to make enemy typing in a game I am making. I am using HardonCollider (HC) to construct polygons for enemy shapes, and for some reason it hates it when I try to pass a table as an argument, instead of a list of raw numbers (in the form func(1,2,3,4,5,6,etc.)). Is there a way to write a function that returns all the values of a table in the form of a,b,c,d,e,f,etc. ?

Something like:

function foo(t)
return t[1], t[2], t[3], t[4], t[5], t[6], etc.
end

But without having to write out a million billion table references.

Code: Select all

unpack( t )

For completeness, here is another way that you really shouldn't use because it is way slower and also less readable than unpack (but the technique is good to know anyway):

Code: Select all

function my_unpack_helper(n, t, ...)
    if n == 0 then  -- end recursion
        return ... 
    end
    return my_unpack_helper(n-1, t, t[n], ...) -- observe the power of tail recursion!
end

function my_unpack(t)
    return my_unpack_helper(#t, t)
end
