Help please....SSCANF issue. - Dokins - 22.01.2012

Alright what happens is.... when i type /housestore it says the first sscanf call "Usage: /housestore [function]"
When I type /housestore money it says /housestore money [amount] when I type the amount it shows the same message!

Can anyone advise me on this?

pawn Code:

CMD:housestore(playerid, params[])
{
    if(LoggedIn[playerid] == 0) return SendClientMessage(playerid, COLOUR_GREY, "You must be logged in to use this command.");

    new cashamount, string[128],function[16], sum;
    new houseid = GetPlayerHouseID(playerid);
    if(sscanf(params, "s[16]D", function, cashamount)) return SendClientMessage(playerid, COLOUR_GREY, "Usage: /housestore [function] Available functions: weapon(coming soon), money");

    if(strcmp(function, "money", true) == 0)
    {
        if(sscanf(function, "d", cashamount)) return SendClientMessage(playerid, COLOUR_GREY, "Usage: /housestore money [amount]");
        if(cashamount < 1 || cashamount > 500000) return SendClientMessage(playerid, COLOUR_GREY, "The amount must be between $0 and $500,000.");
        if(cashamount > PlayerMoney[playerid]) return SendClientMessage(playerid, COLOUR_GREY, "You do not have this much to store.");
        if(HouseOwned[playerid] == houseid)
        {
            printf("House Owned: %d", HouseOwned[playerid]);
            sum = HouseMoney[houseid] += cashamount;
            HouseSQLID[houseid] = MySQL_GetValue(HouseSQLID[houseid], "id", "houses");
            MySQL_SetInteger(HouseSQLID[houseid], "HouseMoney", sum, "houses");
            GivePlayerMoney(playerid, -cashamount);
            printf("Cash amount %d", cashamount);
            format(string, sizeof(string), "You have stored $%d in your house.", cashamount);
            SendClientMessage(playerid, COLOUR_ORANGE, string);
        }

    }
    return 1;
}

Sure can! Take a look at my /give command as a reference.

pawn Code:

pawn Code:

if(sscanf(params, "d",cashamount)) return SendClientMessage(playerid, -1, "Usage: /housestore [amount]");

Re: Help please....SSCANF issue. - Dokins - 23.01.2012

I've tried that before... it doesnt appear to work.

Re: Help please....SSCANF issue. - Scenario - 23.01.2012

I'm surprised you aren't receiving any messages from sscanf in the server console. First of all, you have an optional specifier in the sscanf line (D), change it to a lower-case letter (d). There's no reason for the optional specifier because they can't do anything without it!

And also, your strcmp line doesn't need to have "== 0" at the end. Just doing this will be fine:

pawn Code:

if(strcmp(function, "money", true))

If you still have problems with sscanf, it may be a good idea to download update 2.5 (or whatever the latest version is) because it works for all versions of SA-MP and doesn't have bugs like the previously released version for 0.3d did!

Re: Help please....SSCANF issue. - Dokins - 23.01.2012

I'm sure its an optional one because there are other parameters within the command that could be selected hence why I thought "D" was appropriate (optional integer) It basically returns the client message each time and I've tried an amount of changes to fix it.. I'll update the version.

Re: Help please....SSCANF issue. - Scenario - 23.01.2012

From what I can tell, the only "functions" you have are weapons and money, both probably not needing any further parameters

Re: Help please....SSCANF issue. - Babul - 24.01.2012

1) how can sscanf know where the string ends, and where your amount value is? you forgot to provide a default value for the optional integer aswell:

pawn Code:

if(sscanf(params, "s[16]D"

the optional parameter should look like

pawn Code:

if(sscanf(params, "s[16]D(0)"

...but this is supposed to fail aswell, due to the unknown string end. ("money 123" is stored in the same string atm, where the cashamount=0, not scanned at all)

pawn Code:

if(strcmp(function, "money", true) == 0)

function and params contain the same string, you need sscanf to stop at the " " space char - try to experiment with the search function (here with the space)

pawn Code:

if(sscanf(params, "s[5]' 'D(0)"

...maybe parsing the exact stringlenght [5] will work, but the ' ' search is a neat thing ^^

i didnt try (yet, as its default set to) to scan strings with the space delimeter:

pawn Code:

if(sscanf(params, "p< >s[16]D(0)"

Re: Help please....SSCANF issue. - Dokins - 25.01.2012

Yeah, that still doesnt work.
