hello dear friends,

how can i save the player position in a storage?

and after this, get this position back in another script...

ps:

i need this to work in a "waypoint back" action script
i'm using TFS 1.3, to 10.98 version

I've tried these lines of code:
in first action item:
Lua: 
local storage = 15636  --storage for example

  setPlayerStorageValue(cid, storage, player:getPosition())  -- to save player position

in second action item:
Lua: 
   player:teleportTo(cid, getPlayerStorageValue(cid, 15636))  -- to get position back

but I had this error:
Lua Script Error: [Action Interface]
data/actions/scripts/other/summon.lua:eek:nUse
attempt to index a nil value
stack traceback:
[C]: at 0x7ff6a2e092d0

Lua: 
function Player.savePosition(self, storage)
    self:setStorageValue(storage, self:getPosition().x)
    self:setStorageValue(storage+1, self:getPosition().y)
    self:setStorageValue(storage+2, self:getPosition().z)
end

function Player.loadPosition(self, storage)
    return Position(self:getStorageValue(storage), self:getStorageValue(storage+1), self:getStorageValue(storage+2))
end

-- 15636 = x, 15637 = y,  15638 = z
local start = 15636
player:teleportTo(player:loadPosition(start))

By this way u're using 3 storages. I think it's better to use .gsub and transform positions table to string, and then save it to storage + add function to convert string to table again.

like this ?

Lua: 
local WINDOW_ID = 4203
local BUTTON_ACCEPT = 0
local BUTTON_CLOSE = 1
local storage = 15636 -- < --- storage

local WAYPOINTS_STORAGE = 41875
local WAYPOINTS = {
  [1] = {
    name = "Rhyves Town",
    position = Position(32984, 31284, 6)
  },
  [2] = {
    name = "Deep",
    position = Position(32858, 31291, 8)
  },
  [3] = {
    name = "Firelink Shrine",
    position = Position(32858, 31316, 6)
  },
}

function Player.savePosition(self, storage) -- < -- save function
    self:setStorageValue(storage, self:getPosition().x)
    self:setStorageValue(storage+1, self:getPosition().y)
    self:setStorageValue(storage+2, self:getPosition().z)
end


function onUse(player, item, position, fromPosition)

local itenx = item:getPosition()
  if player:isPlayer() then
  Player.savePosition(self, storage) -- < --- command to save position
   
    for i = 1, #WAYPOINTS do
      local waypoint = WAYPOINTS[i]
      if item:getPosition() == waypoint.position and player:getStorageValue(WAYPOINTS_STORAGE + i) ~= 1 then
        player:setStorageValue(WAYPOINTS_STORAGE + i, 1)
        player:sendTextMessage(MESSAGE_INFO_DESCR, "New waypoint unlocked!\n-- " .. waypoint.name .. " --")
        item:sendMagicEffect(CONST_ME_POFF)
        return true
      end
    end

    local empty = true
    for i = 1, #WAYPOINTS do
      local waypoint = WAYPOINTS[i]
      if item:getPosition() == waypoint.position and player:getStorageValue(WAYPOINTS_STORAGE + i) == 1 then
        empty = false
        break
      end
    end

    if not empty then
      player:registerEvent("WaypointsModal")
     
      local title = "Bonfire Warp"
      local message = "Choose your destination."
     
      local window = ModalWindow(WINDOW_ID, title, message)

      window:addButton(BUTTON_ACCEPT, "Teleport")
      window:addButton(BUTTON_CLOSE, "Close")

      for i = 1, #WAYPOINTS do
        local waypoint = WAYPOINTS[i]
        if player:getStorageValue(WAYPOINTS_STORAGE + i) == 1 then
          window:addChoice(i, waypoint.name)
        end
      end
      window:setDefaultEnterButton(BUTTON_ACCEPT)
      window:setDefaultEscapeButton(BUTTON_CLOSE)

      window:sendToPlayer(player)
    end
  end
    return true
end

function onWaypointsModal(player, modalWindowId, buttonId, choiceId)
  player:unregisterEvent("WaypointsModal")


  if modalWindowId == WINDOW_ID then
      if buttonId == BUTTON_ACCEPT then
      WAYPOINTS[choiceId].position.y = WAYPOINTS[choiceId].position.y + 1
        if player:getStorageValue(WAYPOINTS_STORAGE + choiceId) == 1 then
          player:teleportTo(WAYPOINTS[choiceId].position)
          setPlayerStorageValue(cid, 15636,WAYPOINTS[choiceId].position)
          WAYPOINTS[choiceId].position:sendMagicEffect(CONST_ME_FIREAREA)
          WAYPOINTS[choiceId].position.y = WAYPOINTS[choiceId].position.y - 1
        end
      end
  end
end

i had this error back:

at line 33 change
Lua: 
Player.savePosition(self, storage) -- < --- command to save position
to
Lua: 
player:savePosition(storage) -- < --- command to save position

atleast thats how i understand it by the example code how to load the position

TFS 1.3 does not support storageValues of string type, hence we have to stick to 3 different storageValues
