      Hi!
      We're currently two programmers and a game designer working on a turn-based tactics fantasy board game. For reference you can search for images of "Tactics Arena Online", a fairly dated game that used to have a lot of depth and complexity.
      Our goal is to use the same combat concepts, but giving it a much needed modern touch as well as a whole new set of heroes to choose from with additional abilities. The game is a mix of isometric and 3D and we plan to release the game on Steam and hopefully Android & iOS as well.
      We are looking for someone to work with us pro-bono (just like we're doing) as a 3D character artist. The skills needed are creativity, a hard working attitude and an ability to make minor animations (things like idle, walk, block and very rudimentary attack animations). A perk to have would be the ability to make some VFX. If the game makes it on steam and money starts coming in, you'd obviously be compensated for your hard work, but as it stands this is a hobby project to garnish your portfolio.
      A bit more about the game:
      This game will be an online multiplayer game where each user gets to pick up to 10 characters to place on his half of the board (this would be done before even entering matchmaking. Think runes in League of Legends for example). The user can place his 10 units of choice anywhere he likes on his half board. Some units can be used more than once. So if you want 4 knights and 2 mages or even if you want 10 clerics, you can do as you please. You can then save your setups for future use. The goal of the game is to wipe out the enemy team.
      Each character or Hero (except premium and abyss characters) start with 1 ability and they can ascend (either by playing a certain amount of matches with the character or by forcing the ascension with real money) to gain a new ability or passive. Acquiring a new character can be done by using in-game currency that you earn from playing matches or using real money with the exception of Abyss characters which can only be acquired by winning certain rare matches. The goal is to offer a freemium game with lots of customizable elements while making sure that no user can "buy power" with real money. We want everything that a paying user can get to be available to non-paying users who play the game a lot.
      Ultimately we want this to become a competitive game that people can enjoy and really get invested in. Each character is designed with options for counterplay in mind and synergy with other heroes.
       
      We sincerely believe in what this game can become and we home to find someone just as passionate as we are to get involved in this project!

         Hello , i would like to showcase my first game project, a simple endless casual arcade game called Apples Mania : Apple Catcher. The game has simple goal , scoring as high as possible by collecting falling apples while the difficulty gradually increases. Different apples are worth different amount of points and there are also 2 power-ups to help you in your challenge.
        The game took me about 2 months to complete and polish and i made everything except for the music tracks and some of the sound files. Made in unity and blender3d.
        Would appreciate any kind of feedback.
      Google Play Link

Unity Problem with log functions

Hi, I'm using some code I found on this thread about using SDL_TTF with OpenGL. Part of the code was a maths function, which I can't make work. You'll find the original in that thread I linkified. Here is said function as I have it, in a header file I made:
int nextpowerof2(int x)
{

	double logbase2 = log(x) / log(2); // This line is the culprit
	return round(pow(2,ceil(logbase2)));

}
But the compiler (VS2005 Express Beta 2) kicks up a fuss with the following error, twice on the same line as referenced in the above snippet: error C2668: 'log' : ambiguous call to overloaded function 1> c:\program files\microsoft visual studio 8\vc\include\math.h(553): could be 'long double log(long double)' 1> c:\program files\microsoft visual studio 8\vc\include\math.h(505): or 'float log(float)' 1> c:\program files\microsoft visual studio 8\vc\include\math.h(114): or 'double log(double)' 1> while trying to match the argument list '(int)' The errors are being flagged in cmath and not my own header file. No amount of hacking and working around can stop that - I usually just end up with new errors. If I typecast log(x) to be (double)log(x) there's no change, but if I do:
double log(x)
I'm told double was unexpected (error C2062). I can't make it work, can anybody help me out? Thanks, ukdeveloper.

log((double)x)

If you are going to do it that way, try using the function frexp instead. Something like this:
    int nextpowerof2(int x)
{
int n;
frexp( (double)x, &n );
return n+1;
}
Or, it may be faster and more accurate to do it this way:
    int nextpowerof2( int x )
{
int n = 1;
while ( n < x )
{
n *= 2;
}
return n;
}

The compiler doesn't know whether you want to promote 2 (an int) to a float or a double.
A MUCH MUCH more efficient way of doing what you require is:
!!!Warning: code below assumes 32-bit int's!!!
int nextpowerof2(int x)
{
x |= x >> 1;
x |= x >> 2;
x |= x >> 4;
x |= x >> 8;
x |= x >> 16;
return ++x;
}
[smile]
