Shouldn't maxLen = sizeof (strSrc)? Because you don't want to copy -4 bytes by default.^^
Useful Functions

It's indeed not in correct order as far as I can see. You just have to reverse it for correct output. Also better use a static variable in this case.
29.06.2011, 18:16
No, it's correct. Have tested it now.

And here is the renamed function and it's opposite to reverse it.

The order of both modes are the same, agreed, but what I actually meant is the order of the main order of the bytes itself:
Which should be "1A 2B 3C 4D" as order; that's what I meant with reverse. But that's not very important I think.
pawn Код:
new
byte[4]
;
GetBytes(0x1A2B3C4D, byte[0], byte[1], byte[2], byte[3]);
printf("%02x %02x %02x %02x", byte[0], byte[1], byte[2], byte[3]); // prints "4D 3C 2B 1A"
29.06.2011, 19:08
Oh, thanks, I actually prefer getting it in "correct" order. So I will revert it.

Hey,
I was doing some research on Game development. and I found a few things that could be usefull for samp.
Here's a quick one, its the dot product.
that means, it checks if a player is in someone else's field of view.
The default FoV(Field of View) is around 140, but you can change it while using it
Its untested, but i think my math is fairly good :P
Usage:
Good luck!

That will only work for strings and one variable, if I'm not mistaken. You're better off using the definition ****** created to do the same thing. Except his supports as many variables you want, and of any type.
I hope that's the correct code. I didn't feel like searching through his thousands of posts, and I'm not on a computer to test.

Here another quick function because I got bored a little.
The function is a little bit like 'Random()', but my version only choses from given numbers.
this could be usefull for random skins.
Example:
in this case your skin whil be a 'Law Enforcement' skin.
Код:
stock choose({int,_}:...)
{
new numbers = numargs();
new numb = random(numbers*100); // I added '100' to make it be a bit more random
return getarg(numb/100);
}
this could be usefull for random skins.
Example:
Код:
SetPlayerSkin(playerid, choose(165, 166, 280, 281, 282, 283, 284, 288)
02.07.2011, 17:27
Well, rapgangsta made same function some weeks ago 
stock randoMix(...) return getarg(random(numargs()));
stock randoMix(...) return getarg(random(numargs()));
