Try this.

pawn Код:

stock GivePlayerScore(playerid, score)
{
  if(playerid == INVALID_PLAYER_ID) return -1;
   new amount = GetPlayerScore(playerid);
   SetPlayerScore(playerid, amount+score);
   return 1;
}

If the player isn't connected "-1" is returned. Otherwise, 1 will be returned. Should work fine.
