[Error]Peripheral.find(side): attempt to call nil

Hi all,

So I'm testing some code out for a project I am doing and for some reason the line with

local table = peripheral.find("rcboilertankhightile")

kept return a nil error, so I decided to test it in lua interactive and I got this:

Anyone can help me with this?

NOTES:
Top = wired modem
Left = Monitor
rcboiler… = My steam boilers attached to the network.

P.S. Yes the boilers and the whole network is connected, I check this earlier with some other code and polling worked fine, it's just find peripheral.find(side) that is thorwin an "attempt to call nil" error.

peripheral.find is only available in ComputerCraft 1.6 and later. Based on your CraftOS version, you are running ComputerCraft 1.5x.

Great…I guess I have to wait for the FTB Monster pack to update or do this manually

Well, you can use rs.getSides() in a loop to find it, but if you already know which sides the items are on why no just 'hard code' it? Also, a word of advice…even though you've localized your table (name "table") it's a good idea not to name it "table" - name it myTable or something other than just "table".

He's connecting it through a wired modem, so checking each side isn't really relevant.
The find funciton itself really isn't that hard to do manually, its a pure Lua implementation actually. I don't have 1.6 either, so i don't know what it is exactly, but generally people just use peripheral.getNames instead.

local tBoilers = {}
for k,v in pairs(peirpheral.getNames()) do
  peripheral.getType(v) == "rcboilertankhightile" then
    tBoilers[#tBoilers+1] = peripheral.wrap(v)
  end
end

D'oh - embarrassed that I missed that. Thanks for setting things straight CometWolf :)/>
