How to make a permanant variable - AphexCCFC - 25.04.2014

Hello. How do I make it so when someone uses /createhouse it adds one more onto the id variable, but when I restart the server, the id variable goes back to 0.

pawn Код:

stock CreateHouse(price, Float:PosX, Float:PosY, Float:PosZ)
{
    new string[140], query[300];
    new id = 0; // Here is the ID variable. I want it to save even on game mode restart

    HouseInfo[id][hHouseID] = id;
    HouseInfo[id][hEnterPos][0] = PosX;
    HouseInfo[id][hEnterPos][1] = PosY;
    HouseInfo[id][hEnterPos][2] = PosZ;
    HouseInfo[id][hExitPos][0] = 266.9708;
    HouseInfo[id][hExitPos][1] = 304.9378;
    HouseInfo[id][hExitPos][2] = 999.1484;
    HouseInfo[id][hExitPos][3] = 273.4171;
    HouseInfo[id][hInterior] = 2;
    format(HouseInfo[id][hAddress], 32, "1 San Fierro Drive");
    HouseInfo[id][hPrice] = price;

    format(query, sizeof(query), "INSERT INTO `Houses` (`HouseID`, `Address`, `Price`, `EnterX`, `EnterY`, `EnterZ`, `ExitX`, `ExitY`, `ExitZ`, `ExitA`, `Interior`) VALUES (%d, \'%s\', %d, %f, %f, %f, %f, %f, %f, %f, %d)",
    HouseInfo[id][hHouseID],
    HouseInfo[id][hAddress],
    HouseInfo[id][hPrice],
    HouseInfo[id][hEnterPos][0],
    HouseInfo[id][hEnterPos][1],
    HouseInfo[id][hEnterPos][2],
    HouseInfo[id][hExitPos][0],
    HouseInfo[id][hExitPos][1],
    HouseInfo[id][hExitPos][2],
    HouseInfo[id][hExitPos][3],
    HouseInfo[id][hInterior]
    );

    mysql_function_query(g_Handle, query, false, "", "");

    HouseInfo[id][hPickup] = CreateDynamicPickup(1273, 23, PosX, PosY, PosZ, -1, -1, -1, 100.0);
    format(string,sizeof(string),"HouseID: %d\nAddress: %s\nPrice: %d", HouseInfo[id][hHouseID], HouseInfo[id][hAddress], HouseInfo[id][hPrice]);
    HouseInfo[id][hText] = CreateDynamic3DTextLabel(string, -1, PosX, PosY, PosZ, 25, INVALID_PLAYER_ID, INVALID_VEHICLE_ID, 1, -1, -1, -1, 100);
    id ++; // Here it adds one on each time a house is created
}

Save the value to a file / database and load it afterwards

Ahh found another way so it adds one on when it loads the house rows, thanks.

One more question, how does one make it so when a player exits the house, it sets their facing angle 180 degrees (half turn)?
Tried this but doesn't work:

pawn Код:

SetPlayerFacingAngle(playerid, HouseInfo[i][hEnterPos][3]-180);

you give a value of id to global variable like this..

pawn Код:

//global variable above on GameModeInit()
new housecount;

stock CreateHouse(price, Float:PosX, Float:PosY, Float:PosZ)
{
    new string[140], query[300];
    new id = housescount;

    HouseInfo[id][hHouseID] = id;
    HouseInfo[id][hEnterPos][0] = PosX;
    HouseInfo[id][hEnterPos][1] = PosY;
    HouseInfo[id][hEnterPos][2] = PosZ;
    HouseInfo[id][hExitPos][0] = 266.9708;
    HouseInfo[id][hExitPos][1] = 304.9378;
    HouseInfo[id][hExitPos][2] = 999.1484;
    HouseInfo[id][hExitPos][3] = 273.4171;
    HouseInfo[id][hInterior] = 2;
    format(HouseInfo[id][hAddress], 32, "1 San Fierro Drive");
    HouseInfo[id][hPrice] = price;

    format(query, sizeof(query), "INSERT INTO `Houses` (`HouseID`, `Address`, `Price`, `EnterX`, `EnterY`, `EnterZ`, `ExitX`, `ExitY`, `ExitZ`, `ExitA`, `Interior`) VALUES (%d, \'%s\', %d, %f, %f, %f, %f, %f, %f, %f, %d)",
    HouseInfo[id][hHouseID],
    HouseInfo[id][hAddress],
    HouseInfo[id][hPrice],
    HouseInfo[id][hEnterPos][0],
    HouseInfo[id][hEnterPos][1],
    HouseInfo[id][hEnterPos][2],
    HouseInfo[id][hExitPos][0],
    HouseInfo[id][hExitPos][1],
    HouseInfo[id][hExitPos][2],
    HouseInfo[id][hExitPos][3],
    HouseInfo[id][hInterior]
    );

    mysql_function_query(g_Handle, query, false, "", "");

    HouseInfo[id][hPickup] = CreateDynamicPickup(1273, 23, PosX, PosY, PosZ, -1, -1, -1, 100.0);
    format(string,sizeof(string),"HouseID: %d\nAddress: %s\nPrice: %d", HouseInfo[id][hHouseID], HouseInfo[id][hAddress], HouseInfo[id][hPrice]);
    HouseInfo[id][hText] = CreateDynamic3DTextLabel(string, -1, PosX, PosY, PosZ, 25, INVALID_PLAYER_ID, INVALID_VEHICLE_ID, 1, -1, -1, -1, 100);
    id++; // Here it adds one on each time a house is created
}

obviusly when you restart the server if you don't use any system for save this informations the count back to 0.
