Rednet goes to wrong computer

I have 3 computers attached to each other using bundled cable, however when i send a message from computer 2 to computer 3, computer 1 and 3 get the message from computer 2. Even though rednet.send is set to send to computer 3. Cant work out why this is happening.

Do you have code that we can look at? I don't have any issues like this in any of my programs.

Not sure how your supposed to show code other then screenshots so here goes:

Computer 1, ID 93 (end line cut off):

Computer 2, ID 88:


Computer 3, ID 91:

Or is this more of a bug?

The only issue I see with just looking at the code is you never close the files you open. You add the following.

secret = file.readAll()
secret.close() -- add

Other then that I'm probably going to have to type out the code and try to duplicate your problem. You playing on a Server that don't have access to the file system? If your playing single player you can goto your .minecraft/saves/save_game/computer/computer_id folder and have access to your programs so you can copy and paste them.

Okay I see it. You have()'s if your if statement..

if(id == 91) then

if id == 91 then

You might have to convert id to a number to get it to work properly in the rest of the code as at this point it is a string. do

id = tonumber(id)

to convert it.

The wrong computer still recieves the rednet signal even if i remove that if statement.

Which computer is sending to the incorrect one? All of them? Are you sure you got the id's correct?

"when i send a message from computer 2 to computer 3, computer 1 and 3 get the message from computer 2. Even though rednet.send is set to send to computer 3"

And i listed the ID's on the pictures so you can see they are correct.

It should work. I don't see anything wrong with the code. I'm at work now, will setup a test for this when I get home and see if I can duplicate it. With the way you have your rednet.send command setup it should send to just 91.

Do the other sends that you have setup work properly or do they send to extra/wrong computers as well?

I had a elevator system with like 11 computers in it which worked fine before (only 1 receiving though). Though i do remember having issues with some computers i tried to setup to message to each other on the same rednet line as the elevators.

Ya I would expect to have some issues if sending both rs and rednet commands over the same cable.

It's probably best to use modems for rednet, they are faster and seem to work better.

I'll play around with it some when I get home tonight.

Modems range is awfull though.

You can increase it in the cc config file.

Still be good to know why this problem is happening.

No, seperate cables.

So this appears to be a bug with the bundled cable. If I use bundled cables I can duplicate your error. If I use a modem the code works flawlessly.
