Question

Need to create some table so I can get an info from it in this way:

table[attacker][id]

And if I’ll use

print(table[attacker][id])

It should print the value.

Tried many ways, but haven’t found any good …

I guess it should be something like this…

table.insert(table, attacker, [id] = value)

^ This does not work.

Can someone help me?

Edit

Well, when I try it this way:

x = {}
function xxx()
    if not x[attacker][cid] then
        x[attacker][cid] = value
    else
        x[attacker][cid] = x[attacker][cid] + value
    end
    print(x[attacker][cid])
end

I get an error saying:

attempt to index field ‘?’ (a nil value)

Answer 1

You need the curly braces to create the inner table:

table.insert(my_table, attacker, {[id]=value})

or

-- the advantage of this is that it works even if 'attacker' isn't a number
my_table[attacker] = {[id]=value}

a = 1
b = 2
c = 3
d = {}
table.insert(d, a, {[b]=c})
print(d[a][b]) -- prints '3'
