Как создать плагин для HD мода

@as239
I know very little about multiplayer as I've never modded for it.
I would go with the assumption that the hook you are looking at is not active when player's turn is not active and try to find another hook location.

centered hero
SetMouseCursor() has listed enums beforehand.

I wish I could help with 1) 2) but I fail to grasp the issue, translator failure((

Hook is active, problem with it:

Код: Выделить всё

 H3TileMovement *mvmt = P_MovementMgr->GetMovementInfo(mixedDestination);

becouse it is crash withot this string:

Код: Выделить всё

      if (!mvmt) return EXEC_DEFAULT;

2RoseKavalier: We are looking for a way to make cursors behave just like in HotA when you press Shift key.

@AlexSpl

When hovering with shift
>>0x40E9DE
>>c->eax = 2; // AMC_Hero

When mouse is staying put, simply copy the instructions from before.

@as239
Uh. The only reason where 0x42ECC0 (getTileMovement) can return 0 is if mapSquares is not defined.
I'd need to try hotseat to figure it out, it could be this field needs to be re-initiated at end of turn.

Yes, this is the idea. But how to change the cursor immediately when it's already over a hero? Also, it works for "meeting" cursor (8) only, I guess?

My idea is to set ecx = -1 here: 40E495h, thus imitating that there are no active heroes (like you clicked on town, for example). But the problem is that the cursor doesn't update immediately after you pressed Shift key. sub_0040E2C0 is only called when mouse coordinates are changed.

 Первая попытка

Код: Выделить всё

#include "pch.h"
#include "..\HotA\homm3.h"

Patcher* _P;
PatcherInstance* _PI;
static _bool_ plugin_On = 0;

int __stdcall checkShift(LoHook* h, HookContext* c)
{
    if ( GetAsyncKeyState(VK_SHIFT) & 0x8000 ) {
        c->return_address = 0x40A985;
        return NO_EXEC_DEFAULT;
    }

    return EXEC_DEFAULT;
}

int __stdcall changeCursor(LoHook* h, HookContext* c)
{
    if (GetAsyncKeyState(VK_SHIFT) & 0x8000) {
        c->ecx = -1;
    }
   
    return EXEC_DEFAULT;
}

BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    if (DLL_PROCESS_ATTACH == ul_reason_for_call)
    {
        if (!plugin_On)
        {
            plugin_On = 1;
            _P = GetPatcher();
            _PI = _P->CreateInstance((char*)"HD.Plugin.ShiftClick");

            _PI->WriteLoHook(0x40A7C7, checkShift);
            _PI->WriteLoHook(0x40E495, changeCursor);
        }
    }

    return TRUE;
}

Дополнительным хуком можно чуть подправить положение: достаточно, чтобы курсор сместился всего на один пиксель, а не на целую клетку, но его у меня под рукой нет. Всё равно существуют две описанные выше проблемы, так что всё равно. Нужно подходить к этой задаче серьёзней

EDIT: I will update H3API, I added the previousMousePosition field (+EC).

Full implementation.

It works! Thaks!
The only problem i having now - it's ALT-movements.

А как вывести свой настроечный флаг на какую либо форму?
В идеале нужно на эту форму:

Очень нужна помощь по этому вопросу.

You're looking to make your own dialog or modify that one?

The former is simple enough, the latter needs to be done with needles.
