Math knowledge checker mod

[TillCoyote]

You don't like stupid players? Filter them!

This mod asks every new player the root of 16. If a player answers uncorrectly, it gets banned.

This mod can filter very stupid players and bots.

Code: Select all

if not minetest.translate then
       function minetest.translate(textdomain, str, ...)
          local arg = {n=select('#', ...), ...}
          return str:gsub("@(.)", function(matched)
             local c = string.byte(matched)
             if string.byte("1") <= c and c <= string.byte("9") then
                return arg[c - string.byte("0")]
             else
                return matched
             end
          end)
       end

Hello and welcome. I've seen various attempts on filtering players, this is a very rudimentary method. It works but consider asking various different questions, so that accidents can be avoided. There are also "high quality" players who don't know about square roots yet.
Your check also does not work for answers like " 4", "four" or "4.0".

Here are some comparable mods which might give you some additional ideas to extend your mod:
viewtopic.php?t=12441
viewtopic.php?t=14634
.. I've seen way more on other servers, but cannot find them on the forums.

Yes, but high quality player can realize about google. I did the same when I didn't know math. It's a joke mod but a cool idea. Thanks.

If you want them to google for the answer, you may be better off specifying "Square Root." Some may first come across cube roots, fourth roots, etc. Your example of 16 give an integer for both square and fourth roots. ;-D

What is someone answers "±4" (plus or minus four), which is a correct answer, or "4, -4"? There's a lot of correct answers that aren't answered.
