The method of doing this is really simple.

You might want to make this on your OnPlayerUpdate: Easy way of stopping money hacks

pawn Код:

if(GetPlayerMoney(playerid) != Player[playerid][Money])
        {
            ResetPlayerMoney(playerid);
            GivePlayerMoney(playerid, Player[playerid][Money]);
        }
        if(GetPlayerScore(playerid) != Player[playerid][Level])
        {
            SetPlayerScore(playerid, 0);
            SetPlayerScore(playerid, Player[playerid][Level]);
        }]

Change the variables, obviously.

Then, rather than your method you can do this:

pawn Код:

if(PlayerInfo[playerid][pCash] < 500) return SendClientMessage(playerid, COLOR_GREY, "You don't have enough money");
PlayerInfo[playerid][pRenting] = 1;
SendClientMessage(playerid, COLOR_GREEN, "Enjoy your ride!");
PlayerInfo[playerid][pCash] -= 500;

Using the -= operator we can take a value away from a variable.

Don't do this, an exception will occur:

pawn Код:

PlayerInfo[playerid][pCash] - 500;
