Well, u gotta create ur own XP array to save all the players experience points
something like that

pawn Код:

enum ePlayerInfo
{
    // ....
    XP,
    // ...
};

new PlayerInfo[MAX_PLAYERS][ePlayerInfo]

// Usage
PlayerInfo[playerid][XP] = value;

or you can simply use the score system provided by SAMP by default as an EXP counter
