You can also store 32 true/false values in a single variable if you really want to save memory. By using bit flags.

Код:

enum PLAYER_FLAGS :(<<= 1)
{
    LOGGED_IN = 1,
    IN_RACE
};

new PLAYER_FLAGS: PlayerFlags[MAX_PLAYERS];

//when player logs in...
PlayerFlags[playerid] |= LOGGED_IN;

//when player logs out
PlayerFlags[playerid] &= ~LOGGED_IN;

//check if player is logged in.
if( PlayerFlags[playerid] & LOGGED_IN )
