Thaumcraft 4.2.3.5 and Thaumic Tinkerer 2.5-491 Computercraft Script

Hey there, I have an issue with the DireWolf20 Essentia Script (for version 1.6.4). I almost get it to work but there is 1 explicit error:

Some people say that it is because of the asp in line 67, but this is wrong.
When I perform the Command on line 68 on his own(without the asp on the end), I also get this error message.

The script needs to read out some data from the Jars from TT.
I did the following commands via LUA:
a = peripheral.wrap("tt_aspectContainer_0")
a.getAspects()

(Then I get the content of the jar)

when I perform the following:

a.getAspectCount()
(Then I get the error message: )

Java Exception Thrown: java.lang.ClassCastException: java.util.HashMap cannot be cast to java.lang.String


What can I do to solve this issue?

When I try to get the Methods on this peripheral, it states that he attempts to call nil.
So I can't check out the Methods of this Peripheral.

Kind Regards,
Renjestoo

Line 68 of what you've posted reads:

  essentia[asp] = math.floor(countasp)

I guess you mean line 66?:

countasp = peripheral.call(j, "getAspectCount", asp)

What type is "asp"? I'm guessing table, whereas getAspectCount is probably going to what a string, yeah? Try print(type(asp)) immediately after setting it, and posting the exact output you got from a.getAspects() in the Lua console (all of it, verbatim).

Odds are you aren't getting your function list because you're doing something like a.getMethods() when you should be doing peripheral.getMethods("tt_aspectContainer_0").

Hmmmm, I can't figure out the way you mean it. Do you mean that I shoud edit the script with this? print(type(asp))
or just try it in LUA without the script.

I tried it in LUA, and it seems that I can't use a table????

Sorry if I am a little bit confused.
I can read scripts a little bit, but writing them myself completely is an impossible task for me :P/>.

Maybe you can help me out just a little bit more?

In the Lua console, enter:

a = peripheral.wrap("tt_aspectContainer_0")
a.getAspects()  -- What EXACTLY does this display?
type(a.getAspects()) -- ... and what does this display?

okay

a = peripheral.wrap("tt_aspectContainer_0")
a.getAspects()   -- I get the Content of the jar where the aspects will be in
type(a.getAspects())  -- The only thing I see is "table"

So it seems that:

countasp = peripheral.call(j, "getAspectCount", asp)

can't read out the table it gets in the script with:

function scanEssentia()
    for i,j in ipairs(jars) do
        if peripheral.getType(j) == "tt_aspectContainer" then
            asp = peripheral.call(j, "getAspects")
            countasp = peripheral.call(j, "getAspectCount", asp)
            if countasp > 0 then
                essentia[asp] = math.floor(countasp)
            end
            --	   print(countasp)
            --	 print(asp..":"..countasp)
            --	 print(peripheral.getType(j))
        end
    end
end

when I use for example:

countasp = peripheral.call(j, "getAspectCount", "iter") -- One of the Aspects in TT

it seems to work.

But I want to read it out of a table.

How to do this?

I don't think the "exact" screen output of that second command there is "I get the Content of the jar where the aspects will be in". I'm asking for what it shows you. Precisely. Verbatim. Sic. As it is written. Show me what it shows you.

Ideally, provide this twice - once for when the jar is empty, and once when it's full.

Aahhh okay, then I did't understand it correctly.

when the jar is Empty:

a.getAspects()
-- {}

When the jar is full:

a.getAspects()
-- {
--    "terra",
-- }

when performing this:

peripheral.call("tt_aspectContainer_2", "getAspectCount", "terra")
-- 64

That's much better.

It looks like you should be able to get away with changing this line in the scanEssentia() function:

asp = peripheral.call(j, "getAspects")     -- Set asp to the table the peripheral call returns.

… like so:

asp = peripheral.call(j, "getAspects")[1]  -- Set asp to the first entry in the table the peripheral call returns.

Though since we can assume attempting to count aspects in a jar with nothing in it won't work, and countasp will likely always be more than 0 if a jar contains an aspect, it might be worth re-doing the whole function:

function scanEssentia()
	for i,j in ipairs(jars) do
		if peripheral.getType(j) == "tt_aspectContainer" then
			asp = peripheral.call(j, "getAspects")[1]
			if asp then essentia[asp] = math.floor(peripheral.call(j, "getAspectCount", asp)) end
		end
	end
end

Ahhh well. It seems to work now. Now I have another issue :S :S

I get a message in the button API from Direwolf20
button:33: attempt to perform arithmetic on string.

this is the button API:

local mon = peripheral.wrap("top")
mon.setTextScale(1)
mon.setTextColor(colors.white)
local button={}
mon.setBackgroundColor(colors.black)
function clearTable()
   button = {}
   mon.clear()
end

	  local on = data["active"]
	  if on == true then currColor = colors.lime else currColor = colors.red end
	  fill(name, currColor, data)
   end
end
function toggleButton(name)

   screen()

   mon.setCursorPos((w-string.len(text))/2+1, 1)
   mon.write(text)
end
	
function label(w, h, text)
   mon.setCursorPos(w, h)
   mon.write(text)
end

Hope you can find the error?

PS: here is the link to the API:
http://pastebin.com/HRbMF1Eg

The button API you've got there doesn't appear to match whatever button API the main script was written for.

At a glance, you might be able to sort things out by changing these two functions like so:

function setTable(name, func, param, xmin, xmax, ymin, ymax)
   button[name] = {}
   button[name]["func"] = func
   button[name]["param"] = param
   button[name]["active"] = false
   button[name]["xmin"] = xmin
   button[name]["ymin"] = ymin
   button[name]["xmax"] = xmax
   button[name]["ymax"] = ymax
end

function checkxy(x, y)
   for name, data in pairs(button) do
          if y>=data["ymin"] and  y <= data["ymax"] then
                 if x>=data["xmin"] and x<= data["xmax"] then
                        data["func"](data["param"])
                        return true
                        --data["active"] = not data["active"]
                        --print(name)
                 end
          end
   end
   return false
end

… but there might be more to it than that.

Thanks in advice ;)/>
This worked… But……..
now I get again an error in the first script on line 50: bad argument: table expected, got function

function sortEss(t)
  local keys = {}
  for k in pairs(t) do keys[#keys+1] = k end
		table.sort(keys) -- its this line. It seems correct to me, but okay.... I am not a LUA specialist :P/>  --
		local i = 0
		return function()
		i = i+1
		if keys[i] then
		  return keys[i], t[keys[i]]
		end
  end
end

Looks to me like you're mixing up the line numbers again. It'll be this line that's failing:

for k in pairs(t) do keys[#keys+1] = k end

"t" is supposed to be the "essentia" table defined right up at the top of the script… but that's later overwritten with a function, for who knows what reason. Whoever published this version of the script you're using either didn't intend for it to be used, or they completely failed to test it out first - maybe they uploaded the wrong copy?

Find these two lines:

function essentia(aspect, numAspect)

  essentia(essData[1], essData[2])

… and change them like:

function cookEssentia(aspect, numAspect)

  cookEssentia(essData[1], essData[2])

… and expect further problems.

Hey I changed this and it seems to work. I get a screen with all my essentia and it looks fine.

However, when I want to add some essentia into the jars (via the touchscreen) I get the following message:

http://imgur.com/plPdK9I

it is in the 2nd line of this function of the textutils API:

function unserialize( s )
	local func = loadstring( "return "..s, "unserialize" )
	if func then
		setfenv( func, {} )
		local ok, result = pcall( func )
		if ok then
			return result
		end
	end
	return nil
end

now I really want to know what is triggering this API and function what is showing this error message

I hope you can help me with this once more. I know I am a burdain, but I really want this to work :D/>

function fillEss()
  local essData = {}
  essData[1] = currEssentia
  essData[2] = fillAmt
  essData = textutils.unserialize(essData)  -- Delete this line.
  .
  .
  .

At this point I'm quite curious as to where you got this script. I've taken a bit of a dig around, but can't seem to spot an exact match for it.

Hey there, I have an issue with the DireWolf20 Essentia Script (for version 1.6.4).

Every program of Direwolf20 generates a flood of AAP threads because his scripts aren't really stable most of the time.

Usually, though, the problems stem from his scripts making use of OpenPeripherals, which undergoes all sorts of changes with each release (largely because it has to deal with MineCraft and a slew of other mods changing). Trying to use them with the wrong builds results in missing function errors and whatnot, which is fair enough.

I don't think I've seen a DW20 script like this one before, though - it's simply broken. I mean, look at that last function I quoted. "Define essData as a table, then pass it to a function that tries to convert strings to tables." There are a lot of "this is a DW20 script modified by such-and-such" scripts out there, though, and I'm suspecting this was one of them.

this is a script from DireWolf20, but it is a combination of 2 scripts from him.

the only thing I now get is the following:
test:36: attempt to index ? (a number value)

its this line:

c.pushItemIntoSlot("front", beans[aspect], numAspect,1)

I don't know how to solve this :(/>
Please Help

That explains a lot… Who combined those 2 scripts?

That error means "beans" is a number instead of a table. Could you upload you entire current code to pastebin? Then we'll able to give a better answer.

I thing you got your line numbers mixed up again. Is it perhaps line 34 causing that error?

Could you try sticking a print statement right before that line?

print (beans)

Post the result here.

Certainly not 24/7, if that's what you're expecting.

Let's see, line 34 in your paste:

c.pushItemIntoSlot("front", beans[aspect], numAspect,1)

Before that line, try printing "aspect", "numAspect", and "beans[aspect]".

hmmmm, sadly this doesn't work

That doesn't tell me anything useful.

Try:

function cookEssentia(aspect, numAspect)

        print(aspect)
        print(numAspect)
        print(beans[aspect])

        .

… and don't tell me what "doesn't" happen, tell me what "does"!

Okay, I will do this Step by step.
I added links to pictures from every step I took.
It should be rather easy to follow my issue now.

Ok, that could be handy, but - the computer screen which shows the error (and, at this point, presumably the output of those print statements), what's that saying…?

Look at the last imgur link:
there are 2 pictures there. One showing the "touchscreen" and one showing the Console with the error.

when looking for all steps on the console, I made a new screenshot(there are outputs of every step I took made by the console):

Or is this not the thing you are asking for?

Ah, that's the stuff! :)/>

That empty line before the error is where the script printed nil, indicating that it's "beans[aspect]" that the error's complaining about. Aspect's "terra", so apparently there's no "terra" key in the "beans" table.

This'll be because of line 17:

        data = a.getAspects()

As we were discussing on the last page, a.getApects() returns a table, and we're more interested in the first index of that table. So:

        data = a.getAspects()[1]

YESSS this is what I wanted :D/> :D/> :D/> Its working perfect.
I'm gonna test some more and report if there are more issues. Probably minor issues which should be adding some failsafe lines

The script is finaly fully functioning perfectly.
You can download the script in Computercraft with:
"pastebin get g4KzWGJK AutoEssence"

For the button API type this:
"pastebin get GNKKtzdE button1"


If you want, you can share this script with other people. This is a working script that is automatically refreshing all the aspects on the screen after a request.
