ok so, all players in the map, are stored in a 'Players' array?
and what excactly does chr.elms mean?

anyway thanks alot

and btw. Chrs undeclared identifier?

yes, if world will have multiple players they all will be stored in this array
'elms' function return number of elenets
if(Players.elms()) // means if number of players isn't zero

its used because you can't access 0-th player when it doesn't exist, so first you have to check if it really exists
and then access it

sorry, it should be Players.elms instead of Chrs.elms (I've editied the post)

ok so its kinda error check, so prevent the it from crashing during runtime because it cant find the player? .... or what?

yes
