MAX_PLAYERS is defined in a_samp.inc which is a must to include in any script so I don't see how it would give you an undefined symbol error.

pawn Код:

#include <a_samp>

#undef MAX_PLAYERS
#define MAX_PLAYERS 50

// rest of includes..

and the above is an example to re-define MAX_PLAYERS instead of using 1000 which is the default.
