help with sscanf splitting into a enum - NewerthRoleplay - 22.10.2012

Hey with my house system I have it so a callback called OnHouseLoaded in this callback it should split the data into a enumerator which is stored in the variable: PlayerInfo. However I am not sure it is working as my text label is not being created which leads me to believe it is not storing the data for the X, Y and the Z co-ordinate.

Here is the code I am using:

pawn Код:

public OnHouseLoaded(playerid)
{
    new
        idx,
        result[256];
    mysql_store_result();
    while(mysql_fetch_row_format(result, "|"))
    {
        sscanf(result, "e<is[30]iifffiis[200]>", HouseInfo[idx]);
        new houselabel[200];
        format(houselabel, sizeof(houselabel), "House ID: %i\nHouse Owner: %s\nHouse Price: $%i\nHouseLevel: %i\nUse /buy to buy this house!", HouseInfo[idx][houseid], HouseInfo[idx][howner], HouseInfo[idx][hprice], HouseInfo[idx][hlevel]);
        HouseInfo[idx][hlabel] = Create3DTextLabel(houselabel, COLOR_LIGHTGREEN, HouseInfo[idx][HouseX], HouseInfo[idx][HouseY], HouseInfo[idx][HouseZ], 40.0, 0, 0);
        new string[200], name[MAX_PLAYER_NAME];
        GetPlayerName(playerid, name, sizeof(name));
        format(string, sizeof(string), "Admin: %s has created a new house with the ID: %i", name, HouseInfo[idx][houseid]);
        SendAdminMessage(COLOR_GOLD, string);
        idx++;
    }
    mysql_free_result();
    printf("MySQL: Succesful. Fetched %i rows from the database.", idx+1);
    return 1;
}

at the time of writing this the message that needs to be sent is being sent 3 times, (Obviously for all 3 houses in the DB) and I know why that is, the problem is they all ID 0 : S

Well surely I would not need to as the purpose of the print would be to output the data to test if it is being split however I have tested the data in the message that is being sent

Re: help with sscanf splitting into a enum - NewerthRoleplay - 29.10.2012

I tried it with all the data and with no luck this is with the price, it should be 999 however it is zero:

pawn Код:

[16:25:04] A house with the cost: 0 has been loaded. //Before
[16:25:04] A house with the cost: 0 has been loaded. //After

Here is the code:

pawn Код:

public OnHouseLoaded(playerid)
{
    new
        idx,
        result[256];
    mysql_store_result();
    while(mysql_fetch_row_format(result, "|"))
    {
        new string[256];
        format(string, sizeof(string), "A house with the cost: %i has been loaded.", HouseInfo[idx][hprice]);
        printf(string);
        sscanf(result, "p<|>e<is[30]iifffiis[200]>", HouseInfo[idx]);
        new houselabel[200];
        format(houselabel, sizeof(houselabel), "House ID: %i\nHouse Owner: %s\nHouse Price: $%i\nHouseLevel: %i\nUse /buy to buy this house!", HouseInfo[idx][houseid], HouseInfo[idx][howner], HouseInfo[idx][hprice], HouseInfo[idx][hlevel]);
        format(string, sizeof(string), "A house with the cost: %i has been loaded.", HouseInfo[idx][hprice]);
        printf(string);
        idx++;
    }
    mysql_free_result();
    printf("MySQL: Succesful. Fetched %i rows from the database.", idx+1);
    return 1;
}

Could it be anything to do with my sscanf stock?:

Oh also I kept that in as I got errors without it, but I did not have the sscanf included for some reason, however it is still not functional

Re: help with sscanf splitting into a enum - Babul - 29.10.2012

you are fucking the sscanf up by adding both variants. the best thing you can do: remove the sscanf stock in all your scripts, and #include the plugin. all upcoming errors/warnings are worth being converted to the new syntax, like changing a string "s" to a string with a destination size: "s[30]", or change an optional parameter to have a value: "D(1)".
it also could help us to see how your enum got declared. the order is relevant afaik?
adding debug lines in the house-reading loop will give you all information you need for further debugging, like

Код:

	new debugstring[128];
	format(debugstring, sizeof(debugstring), "House ID: %i Own:%s Pri:$%i Lev:%i",HouseInfo[idx][houseid], HouseInfo[idx][howner],HouseInfo[idx][hprice],HouseInfo[idx][hlevel]);
	SendClientMessageToAll(0xffaaaa00,debugstring);

..so you can see each single loaded house[looped idx]'s data

You're a bit late now, I have given up on that gamemode and I am making a new one which fully uses mysql and I am going to copy some of my commands etc. across.
