Hey, if I understand you correct, you need to add new quest function in source, which will take as argument item vnum. Something like this pc.unequip_item(vnum)

And use it like this (just an example):

when login begin
       if pc.get_map_index() == 113  then
             pc.unequip_item(101)
       end
end

quest login_cal begin
    state start begin
        when login begin
            local mapindex,vnum = 41,71124 or 41,71125 or 41,71126 or 41,71127 or 41,71128 or 1,71124 or 1,71125 or 1,71126 or 1,71127 or 1,71128 or 21,71124 or 21,71125 or 21,71126 or 21,71127 or 21,71128
            if pc.unequip_from_index(mapindex, vnum) then
                syschat(string.format('Item-ul %d a fost dezechipat.',vnum))
            end
        end
    end
end

That only happens when teleport/login or also when you click ctrl + g?

I think this will work:

 

quest login_cal begin
	state start begin
		when login begin
			local t = {
				[1] = {71124, 71125, 71126, 71127, 71128},
				[21] = {71124, 71125, 71126, 71127, 71128},
				[41] = {71124, 71125, 71126, 71127, 71128},
			}
			table.foreach(t, function(mapindex, items)
				for j=1, table.getn(items) do
					if pc.unequip_from_index(mapindex, items[j]) then
						syschat(string.format('Item-ul %d a fost dezechipat.', items[j]))
					end
				end
			end)
		end
	end
end

Try change your quest to this:

Spoiler

quest login_cal begin
    state start begin
        when login begin
            local  info_map = {
                [1] = {41,71124},
                [2] = {41,71125},
                [3] = {41,71126},
                [4] = {41,71127},
                [5] = {41,71128},
                [6] = {1,71124},
                [7] = {1,71125},
                [8] = {1,71126},
                [9] = {1,71127},
                [10] = {1,71128},
                [11] = {21,71124},
                [12] = {21,71125},
                [13] = {21,71126},
                [14] = {21,71127},
                [15] = {21,71128},
            }

            for j =1,15 do
                if pc.unequip_from_index(info_map[j][1], info_map[j][2]) then
                    syschat(string.format('Item-ul %d a fost dezechipat.',info_map[j][2]))
                end
            end
        end
    end
end

If it won't work, then try to debug quest function. Add this line in source before "if (lMapIndex == ch->GetMapIndex())"

sys_err("pc_unequip_from_index lMapIndex :%d vnum:%d", lMapIndex, vnum);

Then you'll see in syserr more info about the problem.

P.S.: Sry for almost the same quest, didn't see xP3NG3Rx reply.

Thx you all for reply. I try with all quest. i put the line to see the erorr in syserr  , and there are :

Spoiler

SYSERR: Jan 18 16:22:28 :: RunState: LUA_ERROR: [string "login_cal"]:19: attempt to call field `unequip_from_index' (a nil value)
SYSERR: Jan 18 16:22:28 :: WriteRunningStateToSyserr: LUA_ERROR: quest login_cal.start click

Try to change c++ quest function to this http://pastebin.com/Um1abyPp

P.S.:

@Denis, in your function, at this part: " if (item->GetVnum() == vnum) " need to be change to " if (item && item->GetVnum() == vnum)". Because if core trying to get vnum from NULL item it leads to crash.

[DeYaN. 28]

I change, didn`t work .. 

 

I put the quest function in questlua_pc.cpp and this is : http://pastebin.com/dP0F9bh3  

And this is the quest:

Spoiler

quest login_cal begin
    state start begin
        when login begin
            local  info_map = {
                [1] = {41,71124},
                [2] = {41,71125},
                [3] = {41,71126},
                [4] = {41,71127},
                [5] = {41,71128},
                [6] = {1,71124},
                [7] = {1,71125},
                [8] = {1,71126},
                [9] = {1,71127},
                [10] = {1,71128},
                [11] = {21,71124},
                [12] = {21,71125},
                [13] = {21,71126},
                [14] = {21,71127},
                [15] = {21,71128},
            }

            for j =1,15 do
                if pc.unequip_from_index(info_map[j][1], info_map[j][2]) then
                    syschat(string.format('Item-ul %d a fost dezechipat.',info_map[j][2]))
                end
            end
        end
    end
end

In syser,same errors...

(1)

In questlua_pc.cpp:

Search for "{ "get_killee_drop_pct",    pc_get_killee_drop_pct    },"
After add this line "{ "unequip_from_index",        pc_unequip_from_index    },"

Like on screen

 

(2)

Also in share/locale/XX/quest/quest_functions you need to add line with "pc.unequip_from_index"
