Standard size of a character sprite

12 December 2015 - 03:32 PM

I want to develop a game for mobile phones.
I'd like the user to be able to touch and drag the character around.
My question is: Is there a optimal size for the sprite? I'd lik it to be as small as possible but also big enough so it won't be a problem to drag it.

thanks :)

Choosing a Machine learning method for a game.

15 October 2014 - 10:02 AM

I'm thinking of developing some kind of a strategy game which will learn how the player plays as the time goes by.
It will probably have to consider a lot of variables in order to reach his best move each time and win.

But i'm a little confused about which learning method I should choose...
which would you recommend?
thanks! :)

Writing a game for mobile phones.

27 September 2013 - 05:54 AM

I'm thinking of writing a game for iPhone/android and  I have some questions:
I read that there are a few game engines that help develop games quickly. Shoud I use them or try to develop a game from scretch?
Is there an engine that you would recommend?
I'm thinking of a game in which the user "looks down" on the characters like in "Fallout", "Red Alert", "Dune" etc. Is it considered a 3D or a 2D game?

thanks :)





Making a "Busy Loop" not consume that much CPU (without Sleep)

18 May 2013 - 09:13 AM


I want to measure a very small period of time ( let's say 0.2 ms).

In order to do this, I'm using busy loop which checks whether or not we waited in the busy loop for the requested time like this:


double startTime = MeasureTime();

double endTime = MeasureTime();

while (endTime - startTime < timeToWait)

     endTime = MeasureTime();



I'd like to use some functions which don't use much CPU in that loop in order to ease the CPU load.

which functions should I use?


thanks :)

Invalid UNWIND_INFO data?

27 April 2013 - 07:44 AM


I'm trying to read the unwind data of some dlls (in this case: ntdll.dll).
I noticed that in some cases I read the data jsut fine, but in other cases I see "garbage".
I used dumpbin to look at the unwind data in the dll and I noticed that when I read "garbage" - dumbin can't read it either.

This is what I see with dumpbin:

  00006EF4 000442AF 000442C3 0014265D
  00006F00 000442C3 000442CD 00142669
  00006F0C 000442CD 000442D9 001444D5
  00006F18 000442D9 000442FD 00147E95
  00006F24 000442FD 00044376 00144679
  00006F30 00044376 000443D0 001448A1
  00006F3C 000443D0 0004442C 001254B0
    Unwind version: 1
    Unwind flags: None
    Size of prologue: 0x0A
    Count of codes: 4
    Unwind codes:
      0A: ALLOC_LARGE, size=0x1A8
      03: PUSH_NONVOL, register=rdi
      02: PUSH_NONVOL, register=rsi

I also noticed that when I resolve an IP to a "garbaged" runtime function,SymFunctionTableAccess64 does something that couldn't find any documnetation of.
So my questions are:
1. Is this really a garbaged unwind info? If not, how can I read its content?
2. What does SymFunctionTableAccess64 do when it handles such "garbage"? Where can I find some documentation for it?
