Anyways, I made this just now:

GetParam
Note: I have not fully tested this - only like 80% of the possible different inputs.

Am I the only one pissed off at strtok? Not sure why but it just annoys me.

Anyways, I made this function as a replacement. It's slightly faster than strtok, and easier to use.

Usage:
pawn Код:
GetParam( string[], param_num );
string is the string you want to look for params in, and param_num is the index of the param you want, starting at 1.
The function will seamlessly trim the string and return it.

Example:
pawn Код:
new params[] = "   I would  like to \t\t\nhave\n   50    bags    of   cheetos.\r\n";
   
    printf( "1: \"%s\"", GetParam( params, 1 ) ); // Prints "I"
    printf( "2: \"%s\"", GetParam( params, 2 ) ); // Prints "would"
    printf( "3: \"%s\"", GetParam( params, 3 ) ); // Prints "like"
    printf( "4: \"%s\"", GetParam( params, 4 ) ); // Prints "to"
    printf( "5: \"%s\"", GetParam( params, 5 ) ); // Prints "have"
    printf( "6: \"%s\"", GetParam( params, 6 ) ); // Prints "50"
    printf( "7: \"%s\"", GetParam( params, 7 ) ); // Prints "bags"
    printf( "8: \"%s\"", GetParam( params, 8 ) ); // Prints "of"
    printf( "9: \"%s\"", GetParam( params, 9 ) ); // Prints "cheetos."
Code:
pawn Код:
stock GetParam( const szString[ ], iParam )
{
    new iSearchPos, iPos, iHoles, szReturn[ 128 ], iFoundParam = -1;
   
    if ( szString[ 0 ] <= 1 ) // Treat \1 as a null character for ZCMD/YCMD compatibility.
        return szReturn; // If the string is empty there's no point in looking for stuff.
   
    iPos = -1;
   
    while ( 2 <= szString[ ++iPos ] <= ' ' ) {} // Trim the beginning of the string.
   
    if ( --iParam == 0 ) // Wether or not we're looking for the first parameter.
    {
       
       
        if (
               ( iSearchPos = strfind( szString, " ", _, iPos ) ) != -1 // Search for a space/tab
            || ( iSearchPos = strfind( szString, "\t", _, iPos ) ) != -1
        )
            strcat( szReturn, szString[ iPos ], iSearchPos + 1 - iPos ); // Put the found part into the return.
        else
            strcat( szReturn, szString[ iPos ] ); // Put the whole thing (except for the first tabs/spaces, if any) into the return.
    }
    else
    {
        while (
               ( iSearchPos = strfind( szString, " ", _, iPos ) ) != -1 // Search for a space/tab
            || ( iSearchPos = strfind( szString, "\t", _, iPos ) ) != -1
        )
        {
back_in_action:
            iPos = iSearchPos;
           
            while ( 2 <= szString[ ++iPos ] <= ' ' ) {} // Skip any whitespace.
           
            if ( iFoundParam != -1 ) // If the previous iteration found a param..
            {
                strcat( szReturn, szString[ iFoundParam ], iPos - iFoundParam ); // Put it into the return string.
               
                iFoundParam = -1;
               
                break; // Then BREAK YOSELF.
            }
           
            if ( ++iHoles == iParam ) // If this current "hole" is in front of the param we're looking for..
                iFoundParam = iPos; // ..let the script know that.
        }
       
        if ( iFoundParam != -1 ) // If a param was found in the last iteration.. (end of the string)
        {
            iSearchPos = strlen( szString ); // Set the next position to the end of the string.
           
            goto back_in_action;
        }
    }
   
    if ( szReturn[ 0 ] )
    {
        // Trim any whitespace on the right side.
        for ( iPos = strlen( szReturn ) - 1; iPos >= 0 && szReturn[ iPos ] <= ' '; iPos-- )
            szReturn[ iPos ] = 0;
    }
   
    return szReturn;
}
oh nice its crashing my server

Код:
CMD:test(playerid,params[])
{
	if((sscanf(params, "s", params[1])) || (sscanf(params, "s", params[2]))) return SendClientMessage(playerid, ADMINRED, "(!)"HEX_WHITE" Usage is /Test <Something>");
	SendClientMessagef(playerid, ADMINRED, "(!)"HEX_WHITE" The first param is %s and the second one is %s.", GetParam(params, 1), GetParam(params, 2));
	return 1;
}

Why do you actually re-release something that is not made by you without even giving credits?

Isn't it easier to just write credits than deleting the whole function? :O

Wonder if anyone's tried mine yet

    }
    else
    {
        SetPlayerPos(playerid, X, Y, Z);
    }
    return 1;
}
since i like suuper clean code, but pawno crashes. the compiler anyway.

That was a benchmark -> A script that compares two scripts / functions or something smilar like that.

I might add that it was a horrible benchmark.

A couple months ago whilst testing the new 0.3c objects, I found this rather interestant and tried to make something fun off it.

Just place the ammount of stairs after 'Desired = ..' and it will create alot of loop stairs to the heaven with the new 0.3c object at the positions :P
p.s: Sorry if it looks abit cheesy, this code is like a couple months old.
pawn Код:
stock StairsToHeaven(Float:X, Float:Y, Float:Z);
{
    new Z_Increase, Quant, Desired;
    Desired = 400; // We're creating 400 stairs!
    do
    {
        Z_Increase += 20;
        Quant += 1;
        CreateObject(18771, X, Y, Z+Z_Increase, 0, 0, 0, 250);
    }
    while (Desired != Quant);
    return 1;
}

For swapping, a simple XOR swap could be done as a macro instead.

XOR swap is slow (as far as I can remember).

I compared the two:

Bench for swap with variable: executes, by average, 2536.06 times/ms.
Bench for swap with xor: executes, by average, 3052.78 times/ms.

Indeed. Well, I probably miss-remembered again. Thanks for correcting.

getNumCountFromAlfabet(input[]);
This function returns the count from the first letter of the input string. If I put 'Hi there' in it, it will get from 'H' the value, which is '8':
A=1
B=2
C=3
etc.
The function:

pawn Код:
stock getNumCountFromAlfabet(input[])
{
    switch(input[0])
    {
        case 'a', 'A': return 1;
        case 'b', 'B': return 2;
        case 'c', 'C': return 3;
        case 'd', 'D': return 4;
        case 'e', 'E': return 5;
        case 'f', 'F': return 6;
        case 'g', 'G': return 7;
        case 'h', 'H': return 8;
        case 'i', 'I': return 9;
        case 'j', 'J': return 10;
        case 'k', 'K': return 11;
        case 'l', 'L': return 12;
        case 'm', 'M': return 13;
        case 'n', 'N': return 14;
        case 'o', 'O': return 15;
        case 'p', 'P': return 16;
        case 'q', 'Q': return 17;
        case 'r', 'R': return 18;
        case 's', 'S': return 19;
        case 't', 'T': return 20;
        case 'u', 'U': return 21;
        case 'v', 'V': return 22;
        case 'w', 'W': return 23;
        case 'x', 'X': return 24;
        case 'y', 'Y': return 25;
        case 'z', 'Z': return 26;
        default: return strval(input[0]);
    }
    return -1;
}
If it's an integer, it will return that. ('9hi there' will return 9).
I am by the way sure it can be made much easier.

Why did I made this?
I am using djson and Whirlpool. After gmx or something else, any password is good to login, so I made a hash function:
pawn Код:
stock hash(input[])
{
    new tmp[2], tmppass[129];
    WP_Hash(tmppass, 129, input);
    for(new i = 0; i < strlen(tmppass); i++){
        switch(tmppass[i]){
            case 'a'..'z', 0..9:    tmp[0]  =   ((tmp[0] + getNumCountFromAlfabet(tmppass[i]) [CENSORED])) * getNumCountFromAlfabet(tmppass[i]);
            case 'A'..'Z':          tmp[0]  =   ((tmp[0] + getNumCountFromAlfabet(tmppass[i]) [CENSORED])) * (100 + getNumCountFromAlfabet(tmppass[i]));
        }
        tmp[1]                              =   ([CENSORED]);
    }
    return [CENSORED];
}
I've censored it so that decrypt is harder. And as you can see, it first encrypts the string to whirlpool, and then I use getNumCountFromAlfabet to get an integer (I could've used that num_hash from dracoblue, but I made my own, I am not sure why).
With this hash, Hi there! You are very smart if you can decrypt this text. will be:
9371648.
However, I don't know why I posted this, because it's the getNumCountFromAlfabet.
And, please tell it if that function can be improved (something like "return 'a'..'z' = 1..26" or something :P)
Reply

Yes, it can be improved:
pawn Код:
stock GetAlphabetIndex(const ch)
{
    return ('a' <= ch <= 'z') ? (ch - 96) : ('A' <= ch <= 'Z') ? (ch - 64) : '\0';
}
Or:
pawn Код:
stock GetAlphabetIndex(const ch)
{
    if('a' <= ch <= 'z')
        return ch - 96;
    else if('A' <= ch <= 'Z')
        return ch - 64;
    else return '\0';
}
Or:
pawn Код:
stock GetAlphabetIndex(const ch)
{
    switch(ch)
    {
        case 'a'..'z': return ch - 96;
        case 'A'..'Z': return ch - 64;
    }
    return '\0';
}
Reply

I knew it was possible :') - Thanks.
By the way, I forgot that 'const' (that's why I'd use input[])
