for loop for loop storing data

[DataHunter 0]

Good day

I am reading a chest full of items, and I want to store the items data for later use.

you can see the snippet of the program and I hope you see what I mean.

How do I store and recall a list of items?

local component = require("component")
 local sides = require("sides")
 local tp = component.transposer

slot = 1
   for i = 1 , slot do
       gis = tp.getItemInSlot(sides,east,i) --store item that is being read to recall later
         if gis then
            gp.label(i) == gis.label
            gp.size(i) == gis.size
            slot = slot + 1
          end

end

 

for i = 1 , slot do -- recall stored item and print

    print(gp.label(i)

    print(gp.size(i)

end

So there's quite a bit wrong with this, for a start the for loop can't be used that way, not in Lua atleast. I'd recomend a while loop which would look something like this.

while true do
	local gis = tp.getItemInSlot(sides,east,i) --store item that is being read to recall later
	if not gis then break end
  	
  	-- Rest of code
  
end

With your list, you first need to create a table before you can reference  gp like that. So at the top of your code you would need something like "local gp = {}". Then when adding to it the simplest way is to use

gp[slot] = gis
-- or if you want to copy it
gp[slot] = {}
gp[slot].label = gis.label
gp[slot].size  = gis.size

In above code I also fixed some other issues where you used the calling syntax "(" and ")" instead of indexing syntax "[" and "]". Also "==" is the equality operator, what you meant to have was "=" the assignment operator.

For the last bit of code the easiest way to do it correctly is using the same indexing you saw in above code (gp[slot].label) and replace slot with #gp

Thanks alot

 

I will try this, Iam still a beginner trying to write an advanced program.

Although I think I will get this to help me.

There is still one question that I have left and that is, I am reading items from a chest and then I print it ona screen. How can I compare all the slots by gp[slot].label and if it is the same then I want to add the gp [slot].size together.

The slots might be scrambled so I need to check all the slots compare then and then save them.  Will it look almost like this?

for i = 1, slot do

 If gp [slot].label == gp .label then

 gp [slot].size = gp [slot].size + gp.size

 gp .label = nil --to remove the compared slot if it was the same

 gp .size = nil

end --if

end --for

function checkDust()
    top = trans.getInventorySize(chest)
    for i = 1,top do
        inventory = trans.getStackInSlot(chest, i)
        if inventory ~= nil then
            for k,v in pairs(inventory) do
                if k == "name" then
                    if v == "minecraft:cobblestone" then
                        trans.transferItem(chest, hammer, 1,i, 1)
                        os.sleep(.5)
                        trans.transferItem(hammer, chest)
                    elseif v == "minecraft:gravel" then
                        trans.transferItem(chest,hammer, 1,i,1)
                        os.sleep(.5)
                        trans.transferItem(hammer, chest)
                    elseif v == "minecraft:sand" then
                        trans.transferItem(chest, hammer, 1,i, 1)
                        os.sleep(.5)
						trans.transferItem(hammer, chest, 1,i,1)
                    elseif v == "exnihloadscensio:blockDust" then
						trans.transferItem(chest, siev, 1,i,1)
					end
                end
            end
        end
    end
end

this is one of my functions on my functions in my sieve program, this is how i check all the slots =), hope its for any use to u
