Item desappears if moved

[Lucas Durais]

Hello otland!

How can I make a item desappears if the player moves it inside the backpack or if he take it out of the backpack??

My tfs version is 1.2

Thanks!!

why would you want to do that?
are you wanting all items do disappear or just a few/one item?

Sorry for the empty explanation.

I'm actually doing a quest that when the player uses a item on the floor, he gets a item inside his backpack.
But if he moves the item inside his backpack or even throws the item on the floor, the item disappears and a message appears.

data/events/scripts/player.lua

replace the function onMoveItem already there with this:

function Player:onMoveItem(item, count, fromPosition, toPosition, fromCylinder, toCylinder)
    if (item:getId() == ITEMID HERE) and (fromPosition.x == CONTAINER_POSITION) then
        item:remove()
        self:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "text here")
        return false
    end
    return true
end

data/events/events.xml

make sure this is enabled:

<event class="Player" method="onMoveItem" enabled="1" />

Works very well if the player moves the item manually. But if he moves another item inside the backpack, nothing happens.
The item that was supposed to desappears moves inside the backpack as well.

what?
you're wanting it to also disappear whenever it gets pushed over a slot?

Yeah... I've changed my mind.. I'll leave it as it is.

Thanks very much for your help as always Xeraphus

well poop
i already made it to where it gets removed like that
well anyways if you want to use it:

local questItem = 2160

local function deleteQuestItem(container)
    for index = container:getSize()-1, 0, -1 do
        local item = container:getItem(index)
        if ItemType(item:getId()):isContainer() then
            deleteQuestItem(item)
        elseif (item:getId() == questItem) then
            item:remove()
            return true
        end
    end
end

debug.sethook(
    function()
        local info = debug.getinfo(2)
        if info and info.name and (info.name == "addItem") then
            local _, player = debug.getlocal(2, 1)
            if player then
                local backpack = player:getSlotItem(CONST_SLOT_BACKPACK)
                if backpack and (backpack:getItemCountById(questItem) >= 1) then
                    deleteQuestItem(backpack)
                end
            end
            return true
        end
    end, "c"
)

function Player:onMoveItem(item, count, fromPosition, toPosition, fromCylinder, toCylinder)
    if (item:getId() == questItem) and (fromPosition.x == CONTAINER_POSITION) then
        item:remove()
        self:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "text here")
        return false
    end
    if (toCylinder:getItemCountById(questItem) >= 1) then
        deleteQuestItem(toCylinder)
    end
    return true
end

Just for curiosity I tried and it works flawless...
You are awesome.

But I'm going to let it as it was.. I think it would become too hard for the players..

Thanks!
