TFS 1.X+ [TFS 1.3] How to do Deep Search in a For Loop in Main Backpack to Searching Items Inside Other Backpacks?

[Yan18]

Hi guys

How to do a deep search for loop to search items in backpacks inside main backpack?

You will have to make a recursive function.

I do exactly that in this function.
I'm sure you can modify it to fit your needs.

TFS 1.4 getListOfContainerItems

Finds all of the items in a container, and returns it as a table. function getListOfContainerItems(container) if not container:isContainer() then return false end local containers, items = {}, {} table.insert(containers, container) while #containers > 0 do...

The main concept is to

• store results in a list
• put the list in function output
• call the same function on subcontainer to get results from it
• merge subcontainer search results with main (or parent) list

example:
(not actual code, just explaination how to do that)

function somekindofsearch(item)
declare main list
normal container search
if items[i]:isContainer() then
  local sublist = somekindofsearch(items[i])
  for k, v in pairs(sublist) do
    insert results to main list
  end
end

return some list
end

Yes, but I wanna know if there are easiest ways, but I think recursive is the only solution for this problem haha. Thanks!

Thanks! I'm gonna look.

  for k, v in pairs(sublist) do
    insert results to main list
  end
end

return some list
end

Yes, pratically it's necessary to do a recursive function as Boy67 said. I wanted to know if there was a easiest ways. But I will do recursive function! Thanks!

Here is another example that uses a repeat loop and only inserts
¡This method always is recursive!

function Container:getItems()
    local index, containers, items = 0, {self}, {}
    repeat
        index = index +1
        local container = containers[index]
        for i = 0, container:getSize() - 1 do  
            local item = container:getItem(i)
            items[#items +1] = item
            if item:isContainer() then
                containers[#containers +1] = item
            end
        end
    until #containers <= index
    return items
end

Although if you are in TFS 1.4+ you should already be able to use the Container.getItems method by default that already come from the sources
This method has a single optional parameter and it is a boolean, container:getItems(true) to get all the elements of all the containers including the same containers

Thanks! This is similar the code of Xikini in topic: TFS 1.4 getListOfContainerItems (https://otland.net/threads/tfs-1-4-getlistofcontaineritems.278178/)

But it is very helpful! Thanks a lot!

It does exactly the same thing, only that it is done with another type of loop, but any one works, I only did it to give more examples of loops to the public who read this

container:getItems(true) - the param is bool recursive and it's coded already so you don't need to do any extra container checks in your loop.
