pawn Код:

CMD:pay(playerid, params[])
{
    new ID, amount;
    if(sscanf(params, "ui", ID, amount)) return SendClientMessage(playerid, COLOR_GREY, "USAGE: {FFFFFF}/pay [ID] [Amount]");

    if(amount > PlayerInfo[playerid][pCash])
        return SendClientMessage(playerid, COLOR_WHITE, "ERROR: You don't have this much!");
        
    if(amount < 0)
        return SendClientMessage(playerid, COLOR_WHITE, "ERROR: Can't go below 0!");
        
    if(ID == INVALID_PLAYER_ID)
        return SendClientMessage(playerid, COLOR_WHITE, "ERROR: This ID is not connected!");

    PlayerInfo[ID][pCash] += amount;
    PlayerInfo[playerid][pCash] -= amount;
    GivePlayerMoney(ID, PlayerInfo[ID][pCash]);
    GivePlayerMoney(playerid, PlayerInfo[playerid][pCash]);
    return 1;
}

It just gives me money as well as the other player.

Instead of doing this.

pawn Код:

GivePlayerMoney(playerid, PlayerInfo[playerid][pCash]);

It would seem more logical to do.

pawn Код:

GivePlayerMoney(playerid, -amount);

Since you want to subtract what they are paying instead of their total money.
