save position

[andree]

hey guys. teleports me in the designated position, after a moment teleports in the former position. the question is how to save the old storage position to be able to return there?

function back(cid, var)
local playerPosition = getCreaturePosition(cid)
doCreatureSetStorage(cid, 5421, '_' .. playerPosition.x .. '_' .. playerPosition.y .. '_' .. playerPosition.z)
local playerPosFromStorage = getCreatureStorage(cid, 5421):explode('_')
doTeleportThing(cid, {x = playerPosFromStorage[1], y = playerPosFromStorage[2], z = playerPosFromStorage[3]})
end

function onCastSpell(cid, var)
local target = getCreatureTarget(cid)
local pos = {x=910, y=897, z=7}
if target == isMonster or isPlayer then
doTeleportThing(cid, pos)
doTeleportThing(target, pos)
end
addEvent(back, 1000, cid)
end

use:

addEvent(back, 1000, cid, pos)

You don't have to use storages.

Example (your code), you can use it. This is final code.

local function back(cid, target, oldPos, oldTos)
    if isCreature(cid) == true then
        doTeleportThing(cid, oldPos)
    end
    if isCreature(target) == true then
        doTeleportThing(target, oldTos)
    end
    return true
end

function onCastSpell(cid, var)
    local target = getCreatureTarget(cid)
    local pos = {x=910, y=897, z=7}
    local oldPos = getCreaturePosition(cid)
    local oldTos = getCreaturePosition(target)

    if isCreature(target) == true then
        doTeleportThing(cid, pos)
        doTeleportThing(target, pos)
    end
    addEvent(back, 1000, cid, target, oldPos, oldTos)
    return true
end

And:

if target == isMonster or isPlayer then

is exactly the same as this:

if isCreature(target) == true then

@EDIT
If you are using addEvent(callback...) that callback function should be a local function.
Remembet to add return true before every last end in a function. Example:

function blablabla(blabla, bla)
     ...blabla
     return true
end

- that's important! If your spell haven't return true at the end ppl might be casting that spell without mana cost and without exhoust!
