You are fast. Why not make two mods, after all, you have two weeks.

The size of a table is not the total number of elements in it but rather the index n where the table has elements indexed by the continuous sequence of 1 to n. Any element with an index outside this sequence is not counted and you must either keep track of the table yourself or run a pairs() on it and tally the elements. Learn the significance between pairs and ipairs. Also look up the pound sign (#).

Also I can objectively state without hyperbole that lua is the greatest programming language ever invented.

Well thnx for the info about table.getn() I indeed didn't know that was his intended behavoiur. I'm still out on judging lua completly, but compared with groovy (other modern script language) it has some strange behaviours that I find mindboggeling it works that way. I've tried some stuff with the # operator ... it works ... but feels weird using it instead of my trusty foreach approach. Sofar I always used ipairs because having the index is handy, but I indeed haven't looked up yet what the significant difference is between ipairs and pairs

hmmm according to http://trac.caspring.org/wiki/LuaPerformance

ipair or pair should never be used , since it's a performance eater, same goes for table.insert ... I'll have some rewriting to do once I get home

Google_Frog wrote:The "no-pairs challenge" can become complicated, I would not recommend it if you are unfamiliar with the language. The difficulty mostly occurs when you have a list of units you want to iterate over as well as index by unitID. In this situation you need 2 tables with indexes to each other and any little mistake in updating these indexes will make the whole thing crash eventually but not necessarily at the time the bug occurred.

P.S since you don't know yet, most of the time I post from my phone so forgive the brief reply
