Are you sure? Everyone is talking about them here.

#4

I just posted something like that, you should check it out

tuple kind of means each one

#5

Ok, so what’s pack then?

30char

#6

I’m not sure, but it’s probably the opposite of unpack, like grouping things together instead of separating them

#7

So converting a table into a tuple?

#8

table.pack() takes a tuple and gives you back a table with each element of the tuple as a seperate value:

local myTable = table.pack("This", "That")
print(myTable[1]) --> This

Edit because this was marked as the solution:

table.unpack() takes a table and gives you back a tuple with each value of the table as a seperate element:

local myTable = {"This", "That"}
local val1, val2 = table.unpack(myTable)
prinr(val2) --> That

Oh, I meant tuple into a table. That’s exactly what I thought. Thanks.

table.pack(...) creates an array with all elements passed through, along with an additional field n which stores the amount of arguments passed through. (select can be used to get this, too)

Equivalent:

local function pack(...)
    return {n=select("#",...),...}
end

table.unpack(list,i,j) returns elements i through j of array list. Default for i is 1, and default for j is #list

(unpack doesn’t support metamethods)

list[i],list[i+1],...,list[j]
