Your name and position functions do the operation but return nothing, so if you execute name(playerid), nothing will be returned, as with the position function, you're not returning the position, you're just saving them in three different floats.

****** & RyDeR:
I didn't thought of using %x, you're right, it much better.

Edit:
I've checked that, and actually, using %x for 1 for example, will return "1" which is not able to be used on coloured chat messages.

Or, if it's in RGBA format:

pawn Код:
format(str, sizeof (str), "{%06x}", colour >>> 8);
Great, I didn't knew that "%0_x" is possible, thanks.

Re: Useful Functions - RyDeR` - 23.02.2011

Yet another version of quickSort implemented (from C++) to PAWN. I tested serveral times and it worked flawless (even a little bit faster than existing versions).

pawn Код:
stock quickSort(array[], left, right)
{
    new
        tempLeft = left,
        tempRight = right,
        pivot = array[(left + right) / 2],
        tempVar
    ;
    while(tempLeft <= tempRight)
    {
        while(array[tempLeft] < pivot) tempLeft++;
        while(array[tempRight] > pivot) tempRight--;
        
        if(tempLeft <= tempRight)
        {
            tempVar = array[tempLeft], array[tempLeft] = array[tempRight], array[tempRight] = tempVar;
            tempLeft++, tempRight--;
        }
    }
    if(left < tempRight) quickSort(array, left, tempRight);
    if(tempLeft < right) quickSort(array, tempLeft, right);
}
Example:
pawn Код:
new
    array[] = { -541, 54, 689, 12, 3, 0, 3, 55, 66, -541, 5468484, -564, 1554, 1656 }
;
quickSort(array, 0, sizeof(array) - 1);
    
for(new i; i != sizeof(array); ++i)
{
    printf("%d", array[i]);
}
Output:
Код:
-564
-541
-541
0
3
3
12
54
55
66
689
1554
1656
5468484


Re: Useful Functions - Sasino97 - 23.02.2011

Is there a function to return if a number is even or uneven?

Example:

stock IsNumberEven(number)
return true/false

etc...

Instead of

new EvenNumbers= {0,2,4,6,8,10,12,14,16,18,20,.... to the infinite?}

Re: Useful Functions - Toribio - 23.02.2011

A number is odd when (number & 1) returns 1 and it's even when it returns 0.

pawn Код:
#define iseven(%1) (((%1) & 1) == 0)
Then, of course !iseven(n) tells when a number is odd.

Re: Useful Functions - dice7 - 24.02.2011

pawn Код:
#define IsOdd(%0) %0 % 2
#define IsEven !IsOdd


Re: Useful Functions - Slice - 27.02.2011

That list will be full with disconnected IDs at the bottom having score 0. A good thing to add would probably be a size limit, which would allow one to loop through only what's neccessary.

Re: Useful Functions - RyDeR` - 27.02.2011

True, I changed the code a bit. Should work good now.

Unluckily I cant watch the video
Could you write an little explanation what this function does
Or what you need to insert in phi / lambda

Re: Useful Functions - smeti - 27.02.2011

GetPlayerFacingAngle(playerid, Lambda); (xy angle) 0-360
Phi = Horizont; (z angle) 0-360

Re: Useful Functions - RyDeR` - 28.02.2011

I edited my code a bit from this post (now, without checking if it's valid (-> code more faster)). Idea comes from JernejL. I just increased the performance of the code.

pawn Код:
stock filterColorTags(string[], bool: gxtTags, bool: sampColors)
{
    if(gxtTags)
    {
        new
            textPos = -1
        ;
        while((textPos = strfind(string, "~", false, (textPos + 1))) != -1)
        {   
            if(string[(textPos + 2)] == '~')
            {
                strdel(string, textPos, (textPos + 3));
            }
        }
    }
    if(sampColors)
    {
        new
            textPos = -1
        ;
        while((textPos = strfind(string, "{", false, (textPos + 1))) != -1)
        {
            if(string[(textPos + 7)] == '}')
            {
                strdel(string, textPos, (textPos + 8));
            }
        }
    }
}


Re: Useful Functions - Slice - 28.02.2011

You're assuming the string is 2 chars longer than any position found for the ~ character. That's not good!
A line ending with a ~ could cause problems with the script. Same goes for {, but that's even worse.

Re: Useful Functions - RyDeR` - 28.02.2011

No problems, works fine. (I just tried it)
