Gumby and debuggers don't seem to get along.

If that's for me, I'm not talking about Java. I'm talking about Netbeans.

Sorry. I didn't notice.

Found a college course on programming and they are teaching C. You can watch the lectures.

Reviving the topic. Just learned C at the university. I was doing some kind of shells for linux, but I think now that I have absorbed the sintax and the basis.

Maybe I can help you now in future in something that requires this.

I was looking at the Daodan_Cheater.c, I got confuse with the memory hacking, because I have not touch this yet in any lessons. For example the defines that you have there like:

#define GSA_camera (0x00000080)

Seems be like a pointer to that memory position, but I was wondering how you could calculate that? Isn't oni memory code allocated differently every time you run it?

I believe that you have a algorithm that does calculate it, there is any source that I can look at, so I can have a little more notion how it works?

Also I started programming c with gcc and gedit, and it was ok for little when the program was little lines, but I couldn't resist and I migrated to complete eclipse c/c++ ide. Love it and how it show the errors.

AEInstaller's GUI is written in a framework called WxWidgets (if I remember correctly). This is what makes it cross-platform (running on both Windows and Mac OS.) It's also the same framework used to write Audacity.

Yeah seems it is a quite popular, pidgin which I use to talk with yahoo guys from here, seems also written with it.

I believe that I will work in next lessons with Windows and it's owns libraries or maybe guis. I will see.

It's a reference to an offset of a struct. A really ugly one. In the beta\unlrealeased version of the Daodan, I scrapped them for real structs.

typedef struct
{
  int TimerMode;
  char TimerName[32];
  int TimerDuration;
  char field_28;
  char gap_29[3];
  int field_2C;
  Letterbox Letterbox;
  char gap_3a[2];
  char field_3C;
  char gap_3d[3];
  int field_40;
  int CutsceneSyncMark;
  char field_48;
  char gap_49[3];
  int field_4C;
  int field_50;
  int field_54;
  int field_58;
  int field_5C;
  int field_60;
  int field_64;
  int field_68;
  int field_6C;
  int field_70;
  int FadeStartTime;
  int FadeEndTime;
  char field_7C;;
  int Camera;
/**more stuff* */
} GameState;

If you add up all the bytes before Camera, you get 0x80

For example...

#define GSA_CAMERA 0x80
GameState tempGS;
GameState* ONgGameState = &tempGS;

//this
GameState->Camera = 1;
//this
*(int *)((char)GameState + offsetof(GameState, Camera)) = 1;
//and this
*(int *)((char)GameState + GSA_CAMERA) = 1;
//Are all the same.

If you do decide to compile that code to check it out, make sure you set alignments to 1 byte boundries:

Thanks. I will look at it. Where can I find some more oni hacking source codes?

The Daodan source repository:

That code only compiles with GCC though, if you are an MSVC user (like me) you will need the beta-beta code. I'll upload that soon, I've been meaning to.
