In Lua, #MapList only returns the amount of items in the array part of the table. It does not keep track of your dictionary (or "named" or "key-value") entries (such as (in your case): Template).

You need to either keep track of the number of items in your table manually, or use a loop to count them.

You can use a self-defined map_length function, as provided here to count things:


function table.map_length(t)
    local c = 0
    for k,v in pairs(t) do
         c = c+1
    end
    return c
end

a = {spam="data1",egg='data2'}

table.map_length(a)

Thanks! I got a way around it though. Abstract_Life 65 — 8y
