How to empty this string? - Anteino - 24.04.2011

Hi all,

I'm having difficulties with file loading for two weeks now and no solutions, I posted several topics on it but no-one seems to know what is going wrong, allright so here goes:

I have a gm which makes you register, the password and username will be saved in a file with Y_ini. When the script loads the password for a player out of that file and put it in Password[playerid], say the playerid is 0 ==> Password[0], that string will be unchanged till the next server restart. This means when player 0 logs out and another player with playerid 0 logs on he can only log in with the password of the previous player because this is still in Password[0]. I want to learn how to empty Password[0], no strdel or other str function will work, strdel does empty the string, but after that no other string can be put in Password[0]. It seems that a string can only once obtain a value out of a file :S I also tried using hash like ****** told me in the link I provided down here but that also doesn't seem to work.

How to solve this?

For more information on this problem see my other thread:

Please no noob responds.

Reset all variables when a player joins, when a player joins in my script I have a stock like. (setting everything to the number 0).

pawn Код:

stock ClearVars(playerid)
{
     Password[playerid] = 0;
};

But I defined Password[playerid] as:

pawn Код:

new Password[MAX_PLAYERS][129]

and your method results in an error about the variable indexed uncorrectly which is understandable .

Re: How to empty this string? - Vince - 24.04.2011

pawn Код:

Password[playerid][0] = EOS;

Should work. EOS = End Of String = '\0'. This effectively empties the string, and if you use the strlen function it will also return 0.

Re: How to empty this string? - Sinner - 24.04.2011

try

PHP код:



for(new i=0; i<MAX_PLAYERS; i++) strcpy(Password[i], "");

This will clear the entire array, you will need the strcpy() stock though:

PHP код:



stock strcpy(dest[], source[])
{
    
    new len = strlen(source), i;
    for (i = 0; i < len; i ++) dest[i] = source[i];
    return 1;
}

Sorry, I missread your question, do;

pawn Код:

Password[playerid][0] = '\0';

EDIT: Lold, double beat, I should learn to refresh before posting..

No, nothing of the above works :S A string which has gotten a value out of a file can NEVER obtain a new value through INI_String, not even if emptied before in ANY way. How do we normally solve this?

Re: How to empty this string? - playbox12 - 24.04.2011

That is really strange, as it should work, ask in the Y_Ini topic, or PM ****** as he is the author of yini.

(this works for me, I use mysql, I hear from other people using dini that this is how they do it aswell).

Yes I tried everything you just mentioned for like 4 times :P
