• Description:

  Here is just a test between the ipairs function and the old style for loops we used.

Code

p = print
a = {}
for i = 1, 10000 do
a[i] = i
end
local t1 = os.time()
for i, v in ipairs(a) do
      new = i
end
local t2 = os.time()
p("Time needed: ", t2 - t1)
for i = 1, #a do
    new = i
end
t3 = os.time()
p("Time needed:", t3 - t2)

like old style is FASTER!
For 1000000 items I get 2 secs for ipairs and 0 for old… lol
