Useful Functions

strCopyEx - Copies a string to another string until it reaches the given delimiter:
pawn Код:
stock strCopyEx(szSrc[], szDest[], const szDelim[], iSize = sizeof(szDest)) {
    new
        iPos
    ;
    if((iPos = strfind(szSrc, szDelim[0], true)) != -1) {
        szSrc[iPos] = EOS;
        iSize = strcat(szDest, szSrc, iSize);
        szSrc[iPos] = szDelim[0];
    }
    else {
        strcat(szDest, szSrc, iSize);
    }
    return iSize;
}
Example(s):
pawn Код:
new
    szStr[] = "This-is-a-test-string-!",
    szDest[7]
;
strCopyEx(szStr[5], szDest, "-");
print(szDest); // Prints "is"

szDest[0] = EOS;

strCopyEx(szStr[15], szDest, "-");
print(szDest); // Prints "string"
Analog to this function:

strExplode - Splits a string in parts (like "explode" in PHP):
pawn Код:
stock strExplode(szStr[], const szDelim[], szOutput[][], const iSize = sizeof(szOutput)) {
    new
        i,
        iPos,
        iLen = strlen(szStr)
    ;
    do {
        iPos += strCopyEx(szStr[iPos], szOutput[i], szDelim[0], iLen) + 1;
    }
    while(iPos < iLen && ++i < iSize);
    return i;
}
Example(s):
pawn Код:
new
    szStr[] = "This-is-a-test-string-!",
    szOutput[6][7] // We have 6 string parts and the biggest length is 7
;
strExplode(szStr, "-", szOutput);

print(szOutput[0]); // This
print(szOutput[1]); // is
print(szOutput[2]); // a
print(szOutput[3]); // test
print(szOutput[4]); // string
print(szOutput[5]); // !

I'm still wondering why you write "sz" before every variable/array you make.

Nice functions, however.

Hungarian notation. The variables are prefixed with their "type".

szTest[] = string, zero-terminated (all strings in PAWN are what's called zero-terminated, i.e. the text ends at the first 0 in that array).
fTest = float
iTest = integer


Also, RyDeR`, you should make sure the length of the 2nd dimension in the output for your explode function has boundary checks. Right now this will cause strange behavior:
pawn Код:
new
        szStr[] = "This-is-a-test-stringgggggg-!",
        szOutput[6][7] // We have 6 string parts and the biggest length is 7
    ;
    strExplode(szStr, "-", szOutput);

LMAO, I use it even on strings/floats/ints now since it does make code look cooler :O

            return 11;

I written up some functions. I guess they will be a heckload handy. Especially to me.

szAmmo and szWeapon is wrong! Those are plain integer variables! Should be iWeapon and iAmmo.

Some little functions I wrote up now, may be useful may not be useful

pawn Код:
#define setnull(%1)                 (%1[0]='\0') // similar to slices - Make a string "NULL"
#define inttobool(%1,%2)            (%2=!!%1) // INT to BOOL
#define Bit8:%1<%2>                 %1[(%2) char] // Creates a "CHAR" array, aka a 8bit array
#define Bit8_Get(%1,%2)             (%1{%2}) // Gets the "CHAR" array value (pretty self explanatory)
#define SetValue_2D(%1)             {_:%1,...} // Sets a value on a "2D" array

new
    Text: Hi[5] = SetValue_2D(INVALID_TEXT_DRAW),
    Bit8: Yo <5>
;

if(Bit8_Get(Yo, playerid) == 25) return true;

I found a little problem with strdel, it seems like it just sets the pos cell to '\0' and still leaves the rest.
Because I was writing a function and in it, it looped backwards through a string to find the last of something, and even though strdel had supposedly deleted from pos 40 it still found the character after this position.

I did a quick print test and deleted part of a string

str[20];
str = "a string that's 20.";
strdel(str, 10, 20);


Then printed the remaining part, that was supposed to be deleted:
print(str[11]);

"hat's 20."

So I made my own version that loops from the start to end and sets them all to 0.
Not sure if this is a function bug or I have a crappy version defined somewhere.
Strings are zero-terminated, meaning they're read until the first zero. Ex:
pawn Код:
new test[] = {'h', 'e', 'l', 'l', 'o', 0, 'w', 'o', 'r', 'l', 'd'};

print(test);
That would print "hello" because the string ends at the 0 after that.

Deleting after the 0 is pretty much useless and inefficient (unless you're planning to use the array for something other than strings).

What about vehicle color & tuning parts? Virtual world? Interior?

That won't disappear on SetVehicleToRespawn (altough color does not, this is 100%) - for the car parts, let me check it in a few minutes.

Edit: I fixed car parts in the code, thanks for suggestion.
Also I am experiencing a small bug: after respraying in a Transfender and then changing plates it will get the original color. Maybe just sync problem.

#define Packed:%1<%2[%3]> %1[%2 char]=!(%3)

new
    Packed: Hey <25["Hi All"]>,
    Packed: Hey1 <25["Hi All"]>

Creates a packed string with a default value however, I am not sure how to make something like "packed_format" so it'll be compatible with these type of "packed" strings. Maybe I am wrong and "format" itself works on such things but yeah, small and easy macro. Yet useful.

Simpler than:

    Hey[25 char] = !"Hi All",
    Hey1[25 char] = !"Hi All";
It's not even shorter.
Not really sure, however to me does look quite more simple (I don't know how but to me it does somehow).

Alright there we go, first un-needed macro created by Lorenc_ posted lol

Useful for debugging. Prints out a human-readable table of a database result.

Example (sorta):
pawn Код:
new DBResult:result = db_query(db, "SELECT * FROM blabla");

db_print_result(result);

db_free_result(result);
Beware that NULL values will cause it to crash, that's not my fault.

Example output:
As you can see some content is cut-off, it's because of the field length limit (which you can easily modify).

Nice function Slice, I'll try it with my sf-cnr gamemode

___

pawn Код:
#define TimeStampPassed(%1,%2)      ((GetTickCount()-%1)>(%2)) // TimeStampPassed(timestampVar, seconds
Usage:
pawn Код:
public OnPlayerUpdate(playerid)
{
    if(TimeStampPassed(p_WeaponUpdate[playerid], 250))
    {
        p_WeaponUpdate[playerid] = GetTickCount();
        SendClientMessage(playerid, -1, "Fart");
    }
    return 1;
}
Simple little macro instead of using timers

Encrypt and Decrypt

Introduction
Simple encryption technique based on Caesar's cipher.

How does it work?
Replaces a character according to the shift parameter.

Functions
pawn Код:
stock encrypt(string[],shift)
{
    for(new i=0; string[i] != '\0'; ++i)
        string[i]+=shift;
}
pawn Код:
stock decrypt(string[],shift)
{
    for(new i=0; string[i] != '\0'; ++i)
        string[i]-=shift;
}
Example
pawn Код:
main()
{
    new string[] = "This is a string.";
    encrypt(string, 13);
    printf("Encrypted String: %s", string);
    decrypt(string, 13);
    printf("Decrypted String: %s", string);
}

    decrypt(string, 13);
    printf("Decrypted String: %s", string);
}
Hmm.. what could this be for? Is this even secure?

Why not capitalizing V? Like DecreasePVar.
And if we have DecreasePVar, we could have IncreasePVar as well:
pawn Код:
#define IncreasePVar(%0,%1,%2) SetPVarInt(%0, %1, GetPVarInt(%0, %1) + %2)
#define DecreasePVar(%0,%1,%2) IncreasePVar(%0, %1, -(%2))
