    int npc_open_shop(lua_State * L)
    {
        int iShopVnum = 0;
        if (lua_gettop(L) == 1)
        {
            if (lua_isnumber(L, 1))
                iShopVnum = (int) lua_tonumber(L, 1);
        }

        if (CQuestManager::instance().GetCurrentNPCCharacterPtr())
            CShopManager::instance().StartShopping(CQuestManager::instance().GetCurrentCharacterPtr(), CQuestManager::instance().GetCurrentNPCCharacterPtr(), iShopVnum);
        else
            sys_err(" !NPCCharacterPtr");

        return 0;
    }

 

Ok this is right.

When you give it from LUA

you can decide to use  npc.shop_open()    or   npc.shop_open(SHOP_VNUM)

this function only work with button quest when i click or select any npc

i want to remove check for npc to open shop

[WeedHex 626]

bool CShopManager::StartShopping(LPCHARACTER pkChr, LPCHARACTER pkChrShopKeeper, int iShopVnum)

 

You're bound to give:

pkChr = CQuestManager::instance().GetCurrentCharacterPtr();

pkChrShopKeeper = CQuestManager::instance().GetCurrentNPCCharacterPtr();

iShopVnum = (int) lua_tonumber(L, 1);

 

If you want to open just from quest kinda letter, you must make a new boolean function to start shopping without pkChrShopKeeper.

You can show your character as a NPC. You just need to add a few variables and write a few situations with that variables prevent from Null pointer or unexpected errors. (I mean crashing game file)
