I know, there are athousand threads about it but I seriously cant figure out how to do it correctly

since Iron Tanks by railcraft are currently broken ( It will always say its empty from the outside blocks, even from the valve ) I tried to use OpenBlocks tanks.

every single one of my tried ended up in errors so I dont even know how it would help describing my progress so far.


I know that "getTankInfo()" works but I cand figure out how to draw it onto a monitor / the computer screen itself.

Is there any simple way of just letting it tell how much is in the tank?

IIRC, getTankInfo() returns a table that contains the info you're looking for. This should get you started (untested)...

local tank = peripheral.wrap(<side in quotes>) --# wrap the tank as a peripheral
local tankInfo = tank.getTankInfo("unknown") --# get the tank info
local tankStats = tankInfo[1] --# store the first table returned
print tankStats.rawName --# print the raw name of the fluid in the tank
print tankStats.amount --# print the amount in the tank
print tankStats.capacity --# print the capacity of the tank

print tankStats.capacity --# print the capacity of the tank

Already tried it that way. This way it will only show the max capacity of the tanks I tried it with.
The lines with the names and the current amount will just stay empty/black which will look like this on the screen:

1 :
2 :
3: 16000

It seems the structure of the data returned has changed since I last worked with tanks. Try this and tell me what you get...

local tank = peripheral.wrap(<side in quotes>)
local tankInfo = tank.getTankInfo("unknown")
local tankStats = tankInfo[1]
for k, v in pairs(tankStats) do
  print(k .. " / " .. v)
end

The answer will be like that:

capacity / 16000 -- it will print the word capacity not the actual capacity
test:5: attempt to concatenate string and table -- test = the name you give the program

Adding a "type" will get rid of that error, while still giving you usable results.

local tank = peripheral.wrap(<side in quotes>)
local tankInfo = tank.getTankInfo("unknown")
local tankStats = tankInfo[1]
for k, v in pairs(tankStats) do
  print(k .. " / " .. type( v ) )
end

The final section of my tutorial covers this.

This ends in kind of the same result.





It will just print the words themselves.

[KingofGamesYami]

That was the intention, now you can inspect the contents table.

local tank = peripheral.wrap(<side in quotes>)
local tankInfo = tank.getTankInfo("unknown")
local tankStats = tankInfo[1]
for k, v in pairs(tankStats.contents) do
  print(k .. " / " .. type( v ) )
end

Sorry, if im retarded or just dumb, but how does the content table help me?

[Dog]

As I understand it, you're interested in the amount in the tank - contents may hold that information.

Yes, I am. But it still only prints the words themselves. :c
Not sure if its still an error on my side or if im using a bugged version

[Dog]

We need the words - that's telling us what is where. Please post the output of the program.

[Obsidia]

tank without anything in it:

test:4: bad argument: table expected, got nil

tank with any fluid in it:

rawName / string
amount / number
name / string
id / number

Nope, that was me.

[Dog]

KingofGamesYami shouldn't that be...

local tank = peripheral.wrap(<side in quotes>)
local tankInfo = tank.getTankInfo("unknown")
local tankStats = tankInfo[1]
if not tankStats.contents then --# tankStats.contents instead of tank.contents
  print( "No fluid" )
else
  print( "Amount: " .. tankStats.contents.amount ) --# tankStats.contents.amount instead of tank.contents.amount
end

Or am I derping?
