First, you should understand that

pawn Код:

#define useless exemple

create a macro, meaning "useless" will be replaced by "exemple" everywhere in your script when you'll compile it (in fact, it happens a bit before the compile itself).

Second, GetMaxPlayers() will read the number of slots from the server config (server.cfg) thought 500 is a constant number.

So, you can't use GetMaxPlayer() to define an array size because it should be a constant number.

So, best you have to do is using

pawn Код:

#define MAX_PLAYERS 500

but using foreach() for your loops.
