Lua Understanding how doors work

[Sortdcz]

Hello,

I'm interested in making a script where you use a key on a locked door that you can only lock up with that specific door key. In order to do this, do I only need the same actionid on the door and the item? Also, will I have to consider that when you use the item on the door again, it should transform back?

Edit: can I also just do this?

function onUse(cid, item, frompos, item2, topos)
    if item.actionid == 21591 then
        doTeleportThing(cid, {x = 1, y = 1, z = 1}, {x = 1, y = 1, z = 1})
        doSendMagicEffect(frompos, CONST_ME_TELEPORT, getCreaturePosition(cid), CONST_ME_TELEPORT)
        return true
    end
end

will this simply if you use the key with aid on the door, tp you to the other side of the door?

Which server do you use?
https://github.com/otland/forgottenserver/blob/master/data/actions/scripts/other/doors.lua#L19-#L29
In the doors.lua in actions you can see how it works, it transforms the door to an open door if the key item actionid is the same as the door actionid.
The key item needs to be added in the table keys and in actions.xml and the door in the table doors.

Here is a small tutorial.

-- Ofcourse, Limos is faster.

Sorry, I use OTServ SVN 0.6.3

this is my keys.lua:

function onUse(cid, item, frompos, item2, topos)
    if (item2.actionid == 0 or
      (isInArray(LOCKED_DOORS, item2.itemid) == false and
       isInArray(LOCKED_DOORS, item2.itemid-1) == false and
        isInArray(LOCKED_DOORS, item2.itemid-2) == false)) then
        return false
    end

    local canOpen = (item.actionid == 10000 or item.actionid == item2.actionid)
    if not(canOpen) then
        doPlayerSendCancel(cid, "The key does not match.")
        return true
    end

    -- Verify if you are opening or closing the door
    if(isInArray(LOCKED_DOORS, item2.itemid) ) then -- Opening
        doTransformItem(item2.uid, item2.itemid+2)
    elseif(isInArray(LOCKED_DOORS, item2.itemid-2) ) then -- Closing and Locking
        doTransformItem(item2.uid, item2.itemid-2)
    else                                                   -- Locking an already closed door
        doTransformItem(item2.uid, item2.itemid-1)
    end
    doSetItemActionId(item2.uid, item2.actionid)

    return true
end

and this is my doors_locked.lua (I don't have doors.lua):

function onUse(cid, item, frompos, item2, topos)
    if(item.actionid == 0) then
        -- This is impossible to happen, but whatever.
        doTransformItem(item.uid, item.itemid+2)
        return true
    end

    doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "It is locked.")
    return true
end

This basicly works the same way, use one of the doors of the LOCKED_DOORS table (or add one) and use same actionid in the door as in the key item and add the key item to actions.xml.
