ComputerCraft Help Please!

[Captain Caleb]

I'm using FTB Infinity and I'm attempting to use the OpenPeripheralsAddons block, the Sensor. However, after wrapped the peripheral, It seems I can't get an output from getPlayers(). I'm unaware how to paste my code into a copy-paste box, so I'll type it out like normal.

s = peripheral.wrap("back")
s.getPlayers()

One anomaly is that when I go into the interactive Lua program built in to the computer, is that the same code works.

Never used the sensor but I think this will print every player

--wrap the peripheral local to make it a local variable
local s = peripheral.wrap("back")
--get a table which I think contain will contain all the players
local players= s.getPlayers()
--loop over the table
for players in pairs(key,value)do
--print the keys and the values of the table
print(key,value)
end

if it does not print the players you at least see what is stored.

Giving me a bios error: test:3: bad argument: table expected, got nil. If I could be more clear, I'd like the sensor to tell me who is in my chamber, so I could have it print the username of the player in the chamber.

You removed the lines that started with -- I suppose.
where you in the range of the sensor?

edit to clarify what happens (if you removed the lines that started with --)
for some reason the sensor gives nil. I taught it would give a table with player names but as I already said I never used it and I can't test it right now.

 

[Captain Caleb]

I typed out the code myself, so I removed the lines, and tried it again with the lines. I was in range of the sensor. Something to note, getPlayers() gives the UUID and the name. When I attempt to print(name) it prints a blank space.

 

[lenscas]

what happens if you do:

s = peripheral.wrap("back")
print(s.getPlayers())

 

[Captain Caleb]

I get table and then a random series of letters and numbers

I think the loop has to look like this:

for key, value in pairs(s.getPlayers()) do
    print(key, value)
end

That should print out the table entries.

I think the loop has to look like this:

for key, value in pairs(s.getPlayers()) do
    print(key, value)
end

That should print out the table entries.

And I know see the derp I made, thats what I get when I write code when I am distracted

@Captain Caleb sorry for derping and wasting your time the above is correct

This seems to fix the problem. Thank you for the help!
