This is for all old strtok uses.

I build this function (strtok) from the beginning and i could optimize it by more than one and a half the original function:

PHP код:
stock strtok(str[], &index, array[20] = ' 'dilimiter[2] = ' ') {
    
format(array, 20str);
    
strdel(array, 0index);
    new 
pos strfind(array, dilimiterfalse);
    if(
pos == -1) array[index] = EOS;
    else {
        array[
pos] = EOS;
        
index += pos;
    }
    
index++;
    return array;

In addition there's the option to insert the result into an array and not just return it.

Speed results:

Код:
< speed > Ron's strtok: 1100
< speed > Original strtok: 1791
Enjoy

Few ms of difference, almost everyone use sscanf instead.

Almost.
This is for the people that not use sscanf...

dunno but some people stick to no plugin version gamemodes/scripts :/

Thought I'd share even though I wouldn't put my hand in fire that it couldn't be made simpler.
Код:
stock IsRPName(name[])
{
	new upos=strfind(name, "_");
	if(isnull(name)) return false;
	if(strlen(name)-2<upos<2) return false;
	for(new i = 0; i < 24; i++)
	{
		if(!name[i]) break;
		if(!i && 65 > name[i] > 90) return false;
		if(name[i] == 95 && i!=upos) return false;
		if(upos && i-upos == 1)
		{
			if(65 > name[i] > 90) return false;
		}
		if(65 <= name[i] <= 90)
		{
			if(!(!i || i==upos+1 || (i==2 && upos>5) || (i==upos+3 && strlen(name)-upos>5))) return false;
		}
		if(97 > name[i] > 122) return false;
	}
	if(upos==-1) return false;
	if(strlen(name)-upos<3) return false;
	return true;
}

This function checks if two line segments intersect.
pawn Код:
/*
Function:
SegmentsIntersect

Parameters:
Float:x1 - The X start point of the first line segment.
Float:y1 - The Y start point of the first line segment.
Float:x2 - The X end point of the first line segment.
Float:y2 - The Y end point of the first line segment.
Float:x3 - The X start point of the second line segment.
Float:y3 - The Y start point of the second line segment.
Float:x4 - The X end point of the second line segment.
Float:y4 - The Y end point of the second line segment.
Float:x - A float to store the X intersection point in, passed by reference.
Float:y - A float to store the Y intersection point in, passed by reference.

Returns:
0 - line segments do not intersect
1 - line segments intersect
*/

stock SegmentsIntersect(Float:x1, Float:y1, Float:x2, Float:y2, Float:x3, Float:y3, Float:x4, Float:y4, &Float:x, &Float:y)
{
    new
        Float:xA = x2 - x1,
        Float:yA = y2 - y1,
        Float:xB = x4 - x3,
        Float:yB = y4 - y3,
        Float:d  = xA * yB - yA * xB;
    if (!d)
    {
        // Lines are parallel, or one or both segments are zero-length
        return 0;
    }
    new
        Float:xC = x3 - x1,
        Float:yC = y3 - y1,
        Float:pA = (xC * yB - yC * xB) / d,
        Float:pB = (xC * yA - yC * xA) / d;
    if (pA < 0 || pA > 1 || pB < 0 || pB > 1)
    {
        return 0;
    }
    // Compute the intersection point
    x = x1 + pA * xA
    y = y1 + pA * yA
    return 1;

Stylock are you able to make a 3D version of that function?

It will be very useful, seeing as this is a 3D game.

You shouldn't enable people to use bad scripting methods.

Right, but if they already used this bad methods, why not optimize that?

It's true, but people that worked already with strtok, in most situation they have to work a lot to change it to sscanf.

Anyway i builded it as a challenge optimize it for me (not for use), i just wanted to see how much hard it to do that.

For example, using "random(100)" you can get a number ranging from 0-100(max, parameter in random), but with "randomNumber()" you choose how many digits you want your number to have.

pawn Код:
public OnFilterScriptInit()
{
    printf("random(100): %d", random(100));
    return 1;
}
Possible outputs:
Код:
random(100): 1
random(100): 5
random(100): 57
random(100): 98
And if you set "RND_NUM_DIG" to "3" for my function "randomNumber()":
pawn Код:
public OnFilterScriptInit()
{
    printf("Random number: %d", randomNumber());
    return 1;
}
Possible outputs:
Код:
Random number: 123
Random number: 359
Random number: 811
Random number: 925
NOTE: I may have not explained this properly, sorry, im not functioning okay today.
Not true, because with your function may happen that 0 is the first digit.

pawn Код:
decode_doors(src, &bonnet, &boot, &driver_door, &passenger_door)
{
    new int[1];
    int[0] = src;
    bonnet = int{3};
    boot = int{2};
    driver_door = int{1};
    passenger_door = int{0};
    return 1;
}

EXAMPLE:
pawn Код:
encode_doors(bonnet, boot, driver_door, passenger_door, behind_driver_door, behind_passenger_door)
{
    #pragma unused behind_driver_door
    #pragma unused behind_passenger_door
    return bonnet | (boot << 8) | (driver_door << 16) | (passenger_door << 24);
}
decode_doors(src, &bonnet, &boot, &driver_door, &passenger_door)
{
    new int[1];
    int[0] = src;
    bonnet = int{3};
    boot = int{2};
    driver_door = int{1};
    passenger_door = int{0};
    return 1;
}

main()
{
 new bonnet, boot, driver_door, passenger_door;
 decode_doors(encode_doors(1, 2, 3, 4, 0, 0), bonnet, boot, driver_door, passenger_door);
 printf("%d | %d | %d | %d", bonnet, boot, driver_door, passenger_door); // Result: "1 | 2 | 3 | 4"
}
Any idea how to implement decode_panels?

Well, guess what! There are only two possibilities (AFAIK) which means you can, for example, check for male and just return false for the others (to improve the function).
