What's the function to replace getContainerCap

[president vankk]

Hello, I was trying convert a code from 0.4 to 1.2 but I got stucked with theses two lines. Don't know what function to use on it.

if(getContainerCap(cid)) then
       doAddContainerItem(doPlayerAddItem(cid, potion.backpack, 1), potion.item, potion.ammount)
end

Thanks.

getContainerCap(cid) <- -> what is this function supposed to do?

Tell me what is the whole function meant to do?

I don't know what your old function do, but I guess this may help:

local bp = Container(cid)
if bp:getCapacity() > bp:getItemHoldingCount() then --bp:getSize() will do the trick too
    --add the item
end

It suppost to be if you have cap then addcontainer (potion.backpack) and in this backpack with potion.item with potion.ammount

@Colors
and which function can I use to add the items at backpack?

Oh... So your function is checking if the player have cap left? The coded I posted above it checks if X container have free slots...
Anyway, you can add items to a container with the following:

container:addItem(itemId[, count/subType = 1[, index = INDEX_WHEREEVER[, flags = 0]]])

Could you give me a example to how use it? I'm trying using it:

local container = player:addItem(potion.backpack)
if not container then
   return true
end

container:addItem(potion.item, potion.ammount)

Fully script:

local POTIONS = {
   [1515] = {cost = 400, backpack = 10519, item = 8704, ammount = 20}, -- small health potion
   [1516] = {cost = 900, backpack = 2000, item = 7618, ammount = 20}
}

function onUse(player, item, fromPosition, target, toPosition, isHotkey)
   local potion = POTIONS[item.actionid]
   if not potion then
     return true
   end

   local container = player:addItem(potion.backpack)
   if not container then
     return true
   end

   if(player:removeMoney(potion.cost)) then
     container:addItem(potion.item, potion.ammount)
     player:getPosition():sendMagicEffect(39)
   else
     player:sendCancelMessage("You need "..potion.cost.." gold coins for a backpack of 100x " .. ItemType(potion.item):getName() .. ".")
   end
   return true
end

You could do something along these lines to check whether the player has enough capacity or room before adding the item.

    local tmpContainer = Game.createItem(potion.backpack)
    if not tmpContainer then
        return true
    end

    tmpContainer:addItem(potion.item, potion.ammount) -- You can check if it's possible to add this item to the container as well (there are plenty of Item & Container methods to play around with)

    if player:addItemEx(tmpContainer) ~= RETURNVALUE_NOERROR then
        player:sendCancelMessage(player:getFreeCapacity() < tmpContainer:getWeight() and RETURNVALUE_NOTENOUGHCAPACITY or RETURNVALUE_NOTENOUGHROOM)
        return true
    end

    -- do something

@Ninja
Didn't understand how to fit into my script. Remove the money then give a backpack of fully item with charges 100.
