Does not work for me. b_update causes a crash in line 67. Attempt to compare __lt on nil and nil

Thank you both. I've made it work now with variables.

As soon I'm finished with work I'll change the code from inspect to detect.

Hi,

I try to make a turtle digging while there is gravel in front of it.

My first test was

  if turtle.forward() == false then
   if turtle.inspect() == true, "minecraft:gravel" then
    while turtle.inspect() == true, "minecraft:gravel" do
	 turtle.dig()
	 sleep(1)
    end
   else
    break
   end
  end

Unfortunately it seems the while command is not able to handle both values at once. Is there a way to make it work or do I have to fill the inspect information to variables first and compare then?

Argh. Thanks. Sorry to waste your time with this

Does not change the result. Still attempt to call nil value

Thanks. One last question. Though its not part of the original I'm not sure if I need to open a new thread. I now try to put the work in functions but it seems I do not know how to submit the table to the function. The content seems to get lost because I always get the message: "attempt to call nil"

function getMaxEnergy(cell)
local count = 0
local i = 0
for i in pairs(cell) do
  count = count + cell[i].getMaxEnergy()
end
print(i)
return(count)
end
cell = {peripheral.find("tile_thermalexpansion_cell_resonant_name")}

print(getMaxEnergy(cell))

Thanks. That was the solution. I thought find (and my variant) look up a part of the string and wrap when the part is found in the peripherals name.

Still it refuses to comply.

x = peripheral.wrap("tile_thermalexpansion_cell_resonant_name_3")

print("Energy: "..x.getEnergyStored("unknown"))
print("Max Energy: "..x.getMaxEnergyStored("unknown"))

This prints:

Energy: 78236235
Max Energy: 80000000

And this prints nothing:

cell = {peripheral.find("tile_thermalexpansion_cell")}

for i = 1, #cell do
  print(cell[i].getEnergyStored())
end

Even when I add the "unknown" to the method.

I've checked find and I've tried to fix my old code. Both result in the same problem. I do not get the data.

function prepare()
cell = {}
local peripheralList = peripheral.getNames()
counter = 0
for Index = 1, #peripheralList do
  if string.find(peripheralList[Index], "tile_thermalexpansion_cell") then
	counter = counter + 1
	cell[counter]=peripheral.wrap(peripheralList[Index])
   end
end
return(cell)
end

cell = prepare()

print(cell[1][1])

cell = {peripheral.find("tile_thermalexpansion_cell")}
print(cell[1][1])

The table seems always to be empty.

If I wrap a single energy cell I get data.

Edit: Oh, if I use just cell[1] I just get the table ID, thus I've used [1][1]. There might be the problem if I haven't understood how table work.

Argh, thanks. I intended to put it in the IF but it seems I mixed it up. I'll try the find.

Hi,

I'm trying to read the energy status of multiple energy cells. I'm trying to make it adaptive so I just have to add more cells and add them to the network and the program recognizes them. Therefore I thought I use function which uses a loop to check for all the cells and add them to a table. Then returns the table. Unfortunately it seems the table is empty when I try to access it from the main program.

function prepare()
cell = {}
local peripheralList = peripheral.getNames()
counter = 0
for Index = 1, #peripheralList do
  counter = counter + 1
  if string.find(peripheralList[Index], "tile_thermalexpansion_cell") then
   cell[counter]=peripheral.wrap(peripheralList[Index])
  end
end
return(cell)
end
function getEnergy()
end

cell = prepare()
print(cell[1].getType())

Thanks. I think I'll go with the piston method.

It seems I always get the "movement obstructed" message. Is there a way around this? It does not matter if its a normal door or a 6x3 garage door from carpenter blocks.

I don't like the idea of having open wall or ceiling elements in my base for the turtles to use.

Thanks. I hope the creator of computercraft will add the support for the other mods at some point.

I'd like to automate the placing of the named blocks but I don't got the orientation of the microblocks right. Is there a way to handle this. Perhaps an addon to computercraft?
