opencomputers { computer { timeout = 5 } }

i can not seem to find this in the config file of opencomputers. where exacly is this located?

yes the database is needed because i use a exportbus from ae2 with this setExportConfiguration(side:number[, slot:number][, database:address, entry:number):boolean function

I am currently working on a bigger project with open computers and have now run into as serious problem: due to the size of the project there are random tick skips of up to 500 ticks (no that is not a  typing error and no it is not constantly lagging) due to these skips some of my robots and computers decide to throw the error "to long without yielding". I know that this is to prevent open computers from going through infinite loops, but in my case i can not get rid of it(and yes they are sleeping and even printing out something).

What i think is happening is that open computers checks when the last command was executed (saved as the tick in which it was done or a ms timer is started) and in case this was longer ago than a specific time limit (in ticks or ms) it will through this error. In my case the tick skips seem to fill out the time limit so that it troughs the error (it even happens to OpenOS!! on robots)

Is there some way to disable this "feature" or prevent the error from showing up(no lag optimizing is not an option i already am in a flatworld with only the spawn chunks being loaded)

OK so i tried integrating your code into my program but very fast i noticed something: i can not download all items because the database upgrade only allows, as far as i know, 81 entries and i have way more ( i remind ~64000 items).

now that i am back at my PC i can give you my original code for going through the items:

local c = require("component")
local s = require("sides")
local event = require("event")

local db = c.database
local ex = c.proxy(c.me_exportbus.address)
local me = c.proxy(c.me_controller.address)
local r = c.redstone
local m = c.modem

args = {...}
m.open(111)
m.setStrength(64)

--z=args[2]
if args[4] then
 minz = args[4]
else
 minz = 0
end
for z=minz,args[2] do
 num = 0
 print(z)
 for x=0,args[3] do
  db.clear(1)
  l = z.."-"..args[1].."-"..(args[3]-x)..".0"
  items = me.getItemsInNetwork({label = l})
  if #items > 0 then
   me.store({label = l},db.address,1)
   print(db.get(1).label)
   ex.setExportConfiguration(5,1,db.address,1)
   ex.exportIntoSlot(5)
   os.sleep(0.1)
   num = num+1
  end
  if num == 40 then
   m.broadcast(111,z)
   os.sleep(10)
   red = r.getInput(5)
   while red == 0 do
    os.sleep(0.1)
    red = r.getInput(5)
   end
   num = 0
  end
 end
 if num > 0 then
  m.broadcast(111,z)
  os.sleep(10)
  red = r.getInput(5)
  while red == 0 do
   os.sleep(0.1)
   red = r.getInput(5)
  end
 end
end

ok thanks i will try it out as soon as i am back at my pc

i get these labels just with

for y=0,ydim do
  for x=0,xdim do
    for z=0,zdim do
      label = string.format("%d-%d-%d",x,y,z)
--    if in ae do something
--    else do nothing
    end
  end
end

and they are just the displayed name of the item (they are OC 3dprints made with the setLabel function)

I am currently in the midst of building a larger open computers project for which i need to go through a lot of blocks with very specific labels (x-y-z, where x,y and z are integers, 0-5-99 for example), which is the only difference that can be found between the blocks without looking at them, that are stored in an ae2 Me system.

The problem: I only know the maximum values for x,y and z, but not which individual block exist. My question is now if there is a way to do a "fuzzy" search (something like "-32-" to find all items containing that string in their label) within the ae2 integration(searching for all of the blocks takes way to long(64000 blocks and more)), so far i have only come across getting all items or only items with an exactly matching label. In case there is no way to do this in the current ae2 integration i would like to request this feature.

MC 1.12.2

OC 1.7.3.146

Maybe try connecting it to a ME-Core directly, it only worked for me in that case with in my program. The interface gave me no items at all.

Hello

i am still working on my 3dprinting programm but found a problem: I can not print colored glass!!

In the attached image you can see different kinds of glass(right) and their result when i use the texture in an 3dprint(left full block): they turn untinted.

they also can not be tinted again using the tint feature of the 3dprinter: They are just a solid block with the assigned color.

ok i will look into it

then i would like to change my question into how the tint setting works

now i only have to wait for a solution of my other problem

thanks again the code now works and you probably tried to use the files with the included printer program but they are not designed for it (wrote a custom simplifying algorithm to print them)

btw, the 3d files that the program downloads sems to be curupted.

thanks for the fast answer and no they are not corrupted but work in progress

Hello

i am trying to download a file use it and delete it again to make space on the hard drive for the next file but i does not delete the file somehow:

 local status, connection = pcall(internet.request, url)
 if not status or not connection then
  print("Download of " .. url .. " failed.")
 else
  local startTime = computer.uptime()
  while true do
   local response, isFinished = pcall(connection.finishConnect)

Hello

i am currently trying to use the textures of flat colored blocks in my 3d print but with the texture picker i always get "flatcoloredblocks:blocks/flatcoloredblock_drywall" which is just a white block.

is there a way to get the colored texture on to the print or is it just not compatible (oc-version:MC1.12.2-1.7.2.67 and flatcoloredblocks-version:mc1.12-6.6)?

ok i changed the programm a bit:

local c = require("component")
local computer = require("computer")
local internet = require("internet")
local f = io.open("test.txt", "wb")

local imax = 0
local xmax = 0
local ymax = 41
local zmax = 1

local TIMEOUT = 5  -- in seconds

local link = "https://raw.githubusercontent.com/LordNocturnus/sf-"
local folder = "/master/"

local pos = 0

for i = 0, imax do
  for xb = pos, xmax do
    for yb = 0, ymax do
      for zb = 0, zmax do
        print(xb, yb, zb)
        local file = xb .. "-" .. yb .. "-" .. zb .. ".mb3d"
        local url = link .. i .. folder .. file
        local status, connection = pcall(internet.request, url)

        if not status or not connection then
          print("Download of " .. url .. " failed.")
        else
          local startTime = computer.uptime()

          while true do
            local response, isFinished = pcall(connection.finishConnect)
            
            if response and isFinished then
              flagg = true
              break
            elseif not response then
              print("Could not connect to " .. url .. ".")
              flagg = false
              break
            elseif computer.uptime() - startTime > TIMEOUT then
              print("Request to " .. url .. " timed out")
              flagg = false
              break
            else
              os.sleep(0.25)
            end
          end
          if flagg == true then
            local f = io.open(file, "wb")

            for chunk in response do
              f:write(chunk)
            end
 
            f:close()
            connection:close()
            flagg = false
          end
        end
      end
    end
  end
end

but now i get for file 0 41 0 (first existing file) in line

for chunk in response do

a "attempt to call a nil value" error

now i get a "attempt to call method 'close' (a table value)" error

Thanks agian for the fast answer.

it successfully downloads a file and times out if there is no file but i get a indexing global value (nil) for this line:

          socket:close()

thanks for the quick answer.

i tried your code but got a compare number with nil in the line and i newer had a 404 error before even with wget it just wrote a empty file

if not status or not response or response.response() >= 400 then

Hello

i am currently trying to download files from github (and yes i know about wget) and i need to know if they exist or not (making a list of all existing files is not feasible, because there is not enough space on the disk for the list).

I tried multiple things:

1. wget and filesystem.size always gave a length of 0 even for existing files

2. copying wget in my own program and setting a flag if there is a chunk works ... but not with every file (all files that exist have the same structure and length) and i need all of the existing ones them

Now i tried to do it myself with internet.request() but i only get 4 files (also the empty ones) then 6 fail and 4 succeed again(see test.txt t = True and f = False). This is because of to many open connections and i do not know how to close them.

The internet.close() from the wiki dose not work for some reason. (attempt to call nil)

How can i detect if the file exists and close the connection after the download?
