Как создать плагин для HD мода

The best way is add one checkbox to that form.
But own dialog is also acceptable.

Hooking by needle, requires latest H3API update.

#pragma pack(push, 1)
struct HDDlg : public H3Dlg
{
   // * +70
   h3func HDproc;
};
#pragma pack(pop)

h3func HWproc;
PatcherInstance *_PI;

int __stdcall _HH_RunDialog(HiHook *h, HDDlg *dlg, int a2);

void GetHWproc()
{
   H3DLL HW;
   HW.GetDLLInfo("HW_SOD.dll");

   BYTE vt_needle[] = { 0xB0, 0xF9, 0x48, 0x00, 0xA0, 0xF0, 0x5F, 0x00 }; // vtable first 2 entries
   DWORD vtDword = HW.NeedleSearchData(vt_needle, sizeof(vt_needle));
   if (vtDword)
   {
      H3DlgVTable * vt = (H3DlgVTable *)vtDword;
      _PI->WriteHiHook((h3func)&vt->runDlg, FUNCPTR_, THISCALL_, _HH_RunDialog); // only hook run dialog from HW mod
   }
}

int __stdcall MyProc(HDDlg * dlg, H3Msg * msg)
{
   if (msg->IsRightClick())
      F_MessageBox("We have hooked this dialog.");

   return STDCALL_2(int, HWproc, dlg, msg);
}

int __stdcall _HH_RunDialog(HiHook *h, HDDlg *dlg, int a2)
{
   if (P_NewGameDlg) // if we're in lobby
   {
      HWproc = dlg->HDproc; // store HW proc
      dlg->HDproc = (h3func)MyProc; // replace with my own proc
      dlg->CreateBlackBox(5, 5, 30, 20); // modify dialog
   }
   return THISCALL_2(int, h->GetDefaultFunc(), dlg, a2); // run dialog
}


result:

Updated H3API, but having crash in this string:

Here is the start (RoseKavalierSDK.cpp):

Код: Выделить всё

void RoseKavalierSDK_init(PatcherInstance *pi)

        ....
   GetHWproc(pi);

How to get RMG_MapItem?
Tried this:

Код: Выделить всё

RMG_MapItem* AAA = RMG_Map::GetMapItem(9,66,0);

Recall that HW_SOD is loaded later so you have to place this function after it is added, the required address I have previously shared.

RMG_MapItem, you need to extract RMG_Main from the stack / registers, e.g.
It is not a fixed address like combat manager or others.

Код: Выделить всё

RMG_Main * rmg = (RMG_Main *)c->esi;
RMG_MapItem * xyz = rmg->GetMapItem(x, y, z);

It works now!
And how to transform that lovely BlackBox to CheckBox?

Take you pick

And how to set text?

It's crashes:

Код: Выделить всё

     H3DlgDefButton *FlagCheckBox = dlg->CreateOnOffCheckbox(190, 37, 30, 20);
     FlagCheckBox->SetText("ААА");

And how to change values?

Each item you see on a dialog is a separate element, including text.
You have to create a separate H3DlgText field to place your description there.

SetText() is for items that contain text themselves: H3DlgText, H3DlgEdit, H3DlgCaptionButton, H3DlgHintBar, H3DlgTextPcx.
I will separate these things better in the future.

Also you will either want to add a button id to use to update your flag, ~or~ use a button with a custom proc (H3DlgCustomButton) which will itself set the needed flags.
In the second case, there is no need to change the dlg proc, this part

Код: Выделить всё

      HWproc = dlg->HDproc; // store HW proc
      dlg->HDproc = (h3func)MyProc; // replace with my own proc

Needs code example for H3DlgCustomButton.
