Cool OS - but many Programs like 'Geoscan', 'Holoclock' etc. are currently still in Russian-Language

I think that the current state with a Computer-Case with Slots for RAM etc is already a combination of Mainboard+PSU+Case, just easier to handle

But what you mean are the difference between CD, USB and Multicore-CPU apart of the texture?

I guess Robot's crafted out 'Creative Computer Case' doesnt need Power

I wrote a topic before but decided to put all questions into one topic.

Next time hit the EDIT button on the bottom-left of your Post and change everything you need.. That whould be better.

1. How do I delete a program? What do I have to type in? I tried "delete [filename]" and "remove [filename]" but I can't figure it out.

 

2. How do I go back to other folders/directories/cd I know how to get into them with "cd [directory]" but I don't know how to go back without rebooting.

As i posted in your other Thread:

Its the same behavior like with Unix / Linux:

 

cd bin
ls
cd ..

cd lib
cd /

In /bin/ you find all Programs you can run.

For a general help type

help

rm

3. For some reason when I make a program in a mounted hdd it makes a copy of it in the main system programs. Is that normal or just me messing something up?

Please post a Screenshot.

Its the same behavior like with Unix / Linux:

cd bin
ls
cd ..

cd lib
cd /

I've coded a simple methode with ComputerCraft to export all Items with a damage value of >= 6 : http://pastebin.com/NbC59sfW

--[[

 For: ComputerCraft

 If the Nuclear Reactor overheats the Robot drops not only depleted Uran Rods into the Trash...
 If your using Applied Energistics (like me) for Supporting the Robot you will have much used Rods after some Days
 which will blow you storages... 
 And here comes this Script in place:
 Extract all used Uran Rods from AE System and split them into a Chest. This Chest can than be linked to another AE or whatever..
 
 Setup:
 - Place an ME_Interface_Block to a Computer.
 - Connect the ME_Interface with your AE Network and to another side of the ME_Interface place a Chest.

--]]


-- Direction from ME_Interface to Chest. Only valid: north, south, west, east, up, down
directionChest = "NORTH"

-- Side of ME_Interface. Only valid sides: left, right, back, front, up, bottom
meInterfaceSide = "back"

-- Export all Items with a minimum or equal damage value of ...
local minDamage = 6

local CheckEvery = 15  -- sec.


--[[ Internal values - DONT change! ]]


local meInterface = peripheral.wrap(meInterfaceSide)

local version = 0.1
local Count = 0

function exportDamagedItems()
    for number,item in pairs(itemList) do
        local ID = item.fingerprint.id
        local DMG = item.fingerprint.dmg
        if (DMG >= minDamage) then
            Count = Count + 1
            meInterface.exportItem(item.fingerprint, directionChest, 1, 0)
            print("("..Count..") Exported "..ID.." with dmg: "..DMG)
        end
    end
end



---[[ Main Program ]]


-- FIXME: only export if enough space in chest is free

while true do
    itemList = meInterface.getAvailableItems()
    exportDamagedItems()
    os.sleep(CheckEvery)
end

But with OpenComputers i still not have a working way

Hello.

Is it possible to add to next OC Version a Feature to edit a Database entry?

I need to modify several Database Entries, but not over the .store() functions...

Thanks!

Do the damaged item in the database and the damaged item in the ME Network have the same damage value?

No. As i sayd: The Items have different damage values..

Since component.me_exportbus.exportIntoSlot needs an entry from a Database Upgrade, the only solution I see right now is to put every possible damage value in the database, though I'm not sure if you can do that since I don't know IC2

Well i can only add max. 81 entries to a Database but i have much more items with different damage values in my ME System (Uranium Rods are stackable but i have ~100 single stacks in the ME Network)

The only idea i had was something with the inventory_controller or geolyzer but i dont know if the ME_Network can get handled like an Inventory? didnt tested that yet..

I need a way to add something to Database without extra peripheral.. something where i can directly access the Database and store/erase entries.... Does anyone know such methode?

What is if you change 'binary' write-mode to normal? -> "w" instead of "wb"

And does the directory 'bankAccounts/' exists?

Add something like

if not fs.isDir("bankAccounts") then
    fs.makeDir("bankAccounts")
end

And btw: instead of using ev.pull("modem_message") inside of a loop you should use event.listen("modem_message", <yourfunction>) but after that you still need something so script doesnt quit -> a loop

E.g.:

if not fs.isDir("bankAccounts") then
  fs.makeDir("bankAccounts")
end

function messageReceived(event, localAddress, remoteAddress, port, senderDistance, message, nick, balance)
  nick = nick or nil
  balance = balance or nil
  if message == "getInfo" then
    ...
  elseif message == "setInfo" then
    local fil = io.open("bankAccounts/"..nick, "w")
    fil:write(balance)
    fil:close()
    net.send(remoteAddress, 15, "done it")
  end
end
event.listen("modem_message", messageReceived)

while true do
  os.sleep(1)
end

If you're sending messages wirelessly, and sometimes they fail to arrive, could it be that your wireless signal strength on the sender is too low?

actually i have set it to 200 but on default the problem was there too..

I'm just not sure if making a command queue is necessary. If all you're sending is a command to turn off a reactor, then it shouldn't matter if that gets executed multiple times, since you can't turn off an already off thing. The extra "off" signals would just be ignored.

Another example is, that the computer always sends a "ping" via broadcast and if a new client (robot) is in network it should get added to a GUI on computer.. but also this "pong" doesnt arrive allways but the robot doesnt repeats again...

Maybe it get clear if you have a look to the code:

Computer: http://pastebin.com/hfjT7e8s ...importend code for this begins @line 199

Robot: http://pastebin.com/FT4UuWdX ...importend code for this begins @line 543

Ooh, I just thought of something. What if you sent a random number as another parameter with the message,(i.e, modem.send(<address>,<port>,"Message",<random #>)) generated every time you click the button to start the command-sending loop? Then, the receiver could store that random number, and if the next command contains the same number, it's a duplicate, and can ignore it. That should work. I believe there's a library called math that has a random number generator.

Mh. You mean that the Client saves the last "random-key" and rechecks it on next received command? Oke... But what is with commands where the Computer requests stuff from Client, but that will not arrive?

PS. Making conversation, I noticed that you're in Germany. Where are you from in Germany? I'm personally from Texas in the US.

Hm. The Problem is that i want to send Commands which the 'receiver' execute. It would be bad if the 'receiver' execute that Command more than one time only coz the 'sender' didnt know that his command got arrived...

As example:

I have a Computer with touch-screen. Now i click on a "OFF" button to tell Robot#1 to turn reactor off. The problem now is that this command not always arrives and i need to click it again...

My idea now was to code something like a queue - a table with 'destinationAddress' and 'command'

local commandQueue = {}
remoteAddress = 'abcde-fghi...'
commandQueue.remoteAddress = 'POWER:OFF'

local proceedCommandQueue = function()
    if (tableLength(commandQueue) > 0) then
        for remoteAddress,command in pairs(commandQueue) do
            wlan.send(remoteAddress, wlanPort, command)
        end
    end
end
event.timer(0.5, proceedCommandQueue)

Is there a way to verify that a modem_message was received?

As i know a send() doesnt means that the message will 100% arrive - even like UDP.

I want to send Commands over Wireless Network but need to be sure that it really arrive and if not to repeat sending it... like a command-queue or so..

An example code whould be helpful

Thanks!

Hi.

Im searching for a methode to export damaged items from an AE2 Network. The Items have different damage values..

My situation:

I have several Nuclear Reactor's which gets controlled by Robots. The Robot's sometimes drops not fully used Uranium Rods back into my AE2 Network to prevent explosion..

Im using a Quantum Network Bridge over 2 dimensions and have no ME_Controller where i want to export the damaged Items, so im using following Setup:

- Adapter connected to a Computer.

- ME_Interface placed on Adapter and connected to my AE2 Network.

- right-clicked an Database-Upgrade in my hand and added an already used " IC2:reactorUraniumQuad " item. After that i put the Database into the Adapter.

- ME_ExportBus connected with Adapter and placed a Chest in front of it.

Now i have tried the following Code:

local component = require('component')
local side = require('sides')
local meExportBus = component.getPrimary('me_exportbus')
local meInterfaceBus = component.getPrimary('me_interface')
local db = component.database

local exportBusSide
for i = 0, 5 do
    if select(2, meExportBus.getConfiguration(i)) ~= "no export bus" then
        exportBusSide = i
        break
    end
end

local entryNum = {}
for i = 1, 81 do
    local item = db.get(i)
    if item then
        entryNum[item.name] = i
    end
end

local itemList = meInterfaceBus.getAvailableItems()
 
for k,v in pairs(itemList) do
    for key,value in pairs(v.fingerprint) do
        if (key == "dmg") and (value >= 10) then
            print("Exporting ".. v.fingerprint.id .." with dmg: "..value)
            meExportBus.setConfiguration(exportBusSide, 1, db.address, entryNum[v.fingerprint.id])
            meExportBus.exportIntoSlot(exportBusSide, 1)
        end
    end
end

My Problem is now that this doesnt work It outputs the print line but it doesnt export any Item

What am i doing wrong?

Thanks!

I'm pretty sure that right clicking or shift+rightclicking the upgrade itself opens a gui that you can manipulate.

I dont get it ... Where you mean should i right-(shift)click the upgrade ?

//EDIT: Now i read it in the in-game-manual: right-clicking with the database in hand.

I cant find Informations about how to add something to the Database component ... Only over the Inventory Controller store() but is there no other way?

Which Informations needs to get add to the Database and how is the fastest/best/easiest way to add that?

Solved: I must craft each Wireless card myself, else they dont get an unique address.

I've also tested it with table.insert() etc but that did nothing change...

But i now found out that all my Robots seems to have the same Address - how can that be?

Does all wireless-cards have the same Address? Thought thats like a NIC mac and is always unique ?

How can i change that?

@Negi: If you/he do something wrong in /etc/rc.d/script.lua or in /etc/rc.cfg than the system will not boot anymore. So i guess its better to do it over /autorun.lua

I have a strange behavior with an Table ...

I have a Script which listens for 'modem_message' events and to get track about 'Clients' i have a same named Table where i want to add each client-robot to it...

The Code looks reduced like:

local component = require("component")
local event = require("event")
local wlan = component.modem

local wlanPort = 7331
wlan.open(wlanPort)
local Clients = {}

function tableLength(T)
    local count = 0
    for k,v in pairs(T) do count = count + 1 end
    return count
end

function addClient(remoteAddress)
    local rcount = (tableLength(Clients) + 1)
    Clients[rcount] = remoteAddress
    print("Added new Client #"..rcount)
end

function messageReceived(event, localAddress, remoteAddress, port, senderDistance, message)
    addClient(remoteAddress)
end

event.listen("modem_message", messageReceived)

while true do
    os.sleep(1)
end

Real code: http://pastebin.com/hfjT7e8s

The Problem is that 'rcount' doesnt get expanded. Its always same

It receives a modem_message, so the event works - thats tested and is not the Problem. Also i know that #Clients can return the table length too but i have a good reason why i did it not that way (#tbl only works for numerical keys)

What am i doing wrong? 

//EDIT: the reduced code works... mmh why not the real?

The 'Creative' Computer-Case (tier 4) doesnt need Power.

Well my english is bad so i hope its oke when i explain it in german? (coz your also from Germany)

Ich hab einen Computer welcher als Wireless-Server fungiert und eine GUI bereitstellt.. Der Server pingt regelmäßig auf einem bestimmten wlan-Port via broadcast, also an "alle".

Dann starte ich einen Client, welcher den PING empfängt, sich die serverAddress merkt und einen PONG mit weiteren Informationen zurück schickt. (sobald er die serverAddress gespeichert hat antwortet er nicht mehr auf den PING).

Der Server soll dann eine weitere Zeile zur GUI hinzufügen, mit ON/OFF Buttons. Dies ist der dynamische Part, damit ich mal 2, mal 4, oder 9 Clients haben kann - also nicht festgelegt, um nicht jedes mal den Code anpassen zu müssen..

Um die Buttons bedienen zu können muss man sich ja die Koordinaten merken - zumindest wenn man das selbst, ohne deine API, schreiben würde... Dazu wollte ich mir die Zeile merken indem ich 'reactorTXT' als Array (oder Table) anlege und die Zeilennummer dort als Key setze -> 'rcount'.

Wäre sowas mit deiner API möglich?

Btw is it possible to generate lable / lablebox 's dynamic ?

Something like:

reactorTXT = {}
reactorTXT[rcount] = gui.label(2,rcount,30,2,101,rgb.orange,rgb.black,nil,nil,txt)

If i try that ill get an error 'not enough memory'

Is there a way to get a list of all available / usefull basic functions which can be used?

Maybe you can update the readme @ github or create a wiki?

Thanks!

Im currently not sure which Layout i should use:

1.: https://goo.gl/QQuazr

2.: https://goo.gl/nWW8wl

3.: https://goo.gl/dVs2nL

Fastest sides are: front, up, down

One of these i must use for Coolant. Maybe also as Trash/Drop to prevent explosion.

But solong i use a Cable i loose one Side.. Now i saw in the API something about Get/Set the wireless redstone input.

Whats that? 

How to use that?
