Title: Help with Iron Tank Level showing on Monitor

I'm trying to get a monitor to show me the liquid level of an Iron Tank from Railcraft. I have a wired modem connected to it and have right clicked it and it says "Peripheral iron_tank_valve_0 connected". Now my only problem is getting a monitor to show the level. I don't know what commands I should give the computer to get it to show it. Can anyone help?

Also, I'm on FTB Unleashed v1.0.3

... I wasn't entirely sure that worked. But, supposing it does, you can find out what functions a particular peripheral has by using the following:

m = peripheral.wrap(side or name) -- either the side of the computer, or the name of the remote peripheral, in this case "iron_tank_valve_0"
for k, v in pairs(m) do
  print(k)
end

And that will print out what the peripheral can do (if anything).

Thanks Omega. I did that and now it says:

getTanks
listMethods

Now the next intuitive thing to try would be :

m = peripheral.wrap(side or name)
print(m.getTanks())

and see what it returns I think it returns a table so then try

m = peripheral.wrap(side or name)
tanksTable = m.getTanks("unknown")
maintank = tanksTable[1]
print(maintank.capacity)
print(maintank.amount)

and finally to print to monitor

m = peripheral.wrap("iron_tank_valve_0")
mon = peripheral.wrap("left")

-- loop so constantly updates
while true do 
  tanksTable = m.getTanks("unknown")
  maintank = tanksTable[1] -- gets data for tank

  -- prints all data to computer
  shell.run('clear')
  for k, v in pairs(maintank) do
	print(tostring(k)..": "..tostring(v))
  end

  -- prints only capacity/amount to monitor
  mon.clear() -- resets monitor
  mon.setCursorPos(1,1)
  mon.write("Capacity: "..maintank.capacity)
  mon.setCursorPos(1,2)
  mon.write("Amount: "..maintank.amount)

  -- waits 5 seconds
  sleep(5)
end

Thanks Last1Here, that worked a little. Now when I start that program it says:

startup:6: attempt to index ? (a nil value)

Is that line 6 where it says "unknown"? Sorry I'm trying to learn all the lua stuff.

worked fine for me


did you wrap the peripheral correctly? (make sure the modem on the tank is red)

[Teralink]

Is there any additonal Mod needed than RailCraft and ComputerCraft? I can't connect the Iron Tank to a CC Computer. The wired Modem doesn't get red and it doesn't say "Peripheral iron_tank_valve_0 connected". Do I have to do something special to connect them?

I'm thankful for every hint!

Kind regards,

Probably OpenPeripheral.

Thanks, it works. =)

If you ask me, I don't see why we have to use getTanks(side), I would much prefer a function like getData that simply returns a table wit the data... Why the double nesting?

Guess I'll have to make an API for that.
