zsakulkill Posted March 26, 2012 Share Posted March 26, 2012 So, I got bored n decided to try n create a wireless signal through computercraft that would activate a redstone signal at the second location. I'd appreciate any input that someone knowledgeable on this topic could contribute. My current script has no error, but doesn't work as hoped (just btw, modem is on the left of the computer) ___________________________________________ pass = "zsakul" rednet.open("left") rednet.receive(999999999999999) input = read() if input == pass then exit() -------- (where i suspect problem occurs) redstone.output("back", true) else os.reboot() end ____________________________________________ The script on the sending computer works fine, so i don't need to post it.

freakachu Posted March 26, 2012 Share Posted March 26, 2012 yeah, exit() completely stops your program and just quits. why not try using a loop? pass="zsakul" renet.open("left") while true do input = read() if input == pass then redstone.output("back", true) end end basically what this does is loop forever waiting for a a rednet message, then set the redstone output to true when it finally gets the password. it's obviously barebones and doesn't turn it off, but there you go.

zsakulkill Posted March 26, 2012 Author Share Posted March 26, 2012 thanks for trying, but unfortunately that script doesn't even put the computer into the state to receive a message (rednet.receive(x)) also, the script seems to be complete as soon as it starts. Thanks for the try though =) Link to comment Share on other sites More sharing options...
ruben654 Posted March 26, 2012 Share Posted March 26, 2012 If I'm right this should work: rednet.open("left") while true do senderID, input = rednet.receive() if input == "zsakul" then redstone.output("back", true) end end rednet.receive() doesn't have a required timeout setting, if you don't set it it doesn't have a timeout And I suggest you put something in your code to turn the redstone off again like: rednet.open("left") while true do senderID, input = rednet.receive() if input == "zsakul" then redstone.setOutput("back", true) sleep(1) --wait one second redstone.setOutput("back", false) end end Link to comment Share on other sites More sharing options...
zsakulkill Posted March 26, 2012 Author Share Posted March 26, 2012 That is beautiful, tyvm, if you have some time to kill then something else that would be useful would be instead of a timed delay, sending another command to disable the redstone. Also a nice touch would be a script to send the command from the first computer without having to type lua rednet.broadcast("x") exit() EDIT: I edited the script to have the on off feature, but i still havn't designed a system of just typing in the word on the first computer without entering lua Link to comment Share on other sites More sharing options...
ruben654 Posted March 26, 2012 Share Posted March 26, 2012 You could always make a new program with a convenient name that does this: rednet.open("yoursidehere") rednet.broadcast("yourmessagehere") rednet.close("yoursidehere") if you want it send on redstone this will help: rednet.open("yoursidehere") while !(event=="char" and p1=="q") do event,p1=os.pullEvent() if event=="redstone" then if redstone.getInput("yoursidehere") then rednet.broadcast("onmessage") else rednet.broadcast("offmessage") end end end rednet.close("yoursidehere") and if you press Q in the bottom program, it'll terminate the program and turn off the modem Link to comment Share on other sites More sharing options...
zsakulkill Posted March 26, 2012 Author Share Posted March 26, 2012 thanks man, you're help is much appreciated, in the end this is what my script ended up looking like. _______________________________________________________________ Sending computer. rednet.open("left") while true do input = read() if input == "zsakul" then rednet.broadcast("zsakul") print("Z sent") sleep(5) else if inpiut == "shutdown" then rednet.broadcast("shutdown") print("S sent") sleep(5) os.reboot() else print("Null") sleep(5) os.reboot() end end end __________________________________________________ Receiving computer. rednet.open("left") while true do senderID, input = rednet.receive() if input == "zsakul" then redstone.setOutput("back", true ) else if input == "shutdown" then redstone.setOutput("back", false ) os.reboot() end end end _________________________________________ I used to know this but I forgot, whats the command to clear the monitor?

ruben654 Posted March 27, 2012 Share Posted March 27, 2012 It's term.clear() if I remember correctly Link to comment Share on other sites More sharing options...
zsakulkill Posted March 31, 2012 Author Share Posted March 31, 2012 yup term.clear() found it a while back but ty nevertheless. Another useful one after it is term.setCursorPos(1,1) to reset the mouse to the top Link to comment Share on other sites More sharing options...
Pedonymous Posted March 31, 2012 Share Posted March 31, 2012 Might as well ask this here... I was wondering if it would be possible to create a wireless network capable of sending files and chat messages on a Tekkit server. The idea was that each computer could be attached to two wireless transmitters (one for incoming, one for outgoing), which would connect to a central "server" which would relay the data to the desired computer on the network. This would be really cool to see on a server where there is no world chat, making long-distance communication impossible. How hard would it be?

I'm sorry to say this wouldn't be practical =/ Wireless modems have limited capabilities. The signal only carries for a distance of approx 60 blocks in good weather, and approx 17 in rain. However the using the same script I've used you'd just need to input a print("X") command after the signal is received, I've seen people do it before.

Taranis Posted April 1, 2012 Share Posted April 1, 2012 What if I used a wireless redstone transmitter? Or do they not work the same? The wireless redstone transmitter can only transfer redstone signals (on/off) so you would have to recode your message into binary and transfer it bit by bit. The receiver could then recode your message to characters again. No idea what frequency you could use, but I think it would be rather slow and unreliable.

In that case, we need proper transmitters. Link to comment Share on other sites More sharing options...
zsakulkill Posted April 1, 2012 Author Share Posted April 1, 2012 There is actually one alternative I just rememered.... Its a bit extreme though, you can connect all your computers using different color power cables to a router computer (with all the colors going into it) then have that computer relay the signal back down the network the the computer you specify the message is for, kinda a buzz kill and sooooo much cable... but it does work...

freakachu Posted April 2, 2012 Share Posted April 2, 2012 or you could use the http api, which actually would involve using a real for sure server not built inside minecraft. I am pretty sure I saw an IRC client for computercraft over at the mod's own forums. Link to comment Share on other sites More sharing options...

Do you think you could show me some diagrams or something? Sounds like it'd be good for long-distance communication in combination with chunk loaders.

zsakulkill Posted April 3, 2012 Author Share Posted April 3, 2012 Well its pretty straight forward, the maximum amount of computers on the network would be the maximum amount of colors of cable u have, minus one for the computer running your server which has to be connected to all the colors. Also, i don't know if there's a limit to the distance the colored wires can go. Link to comment Share on other sites More sharing options...

Also, i don't know if there's a limit to the distance the colored wires can go. The limit of wires is 128 blocks, but they can be refreshed with a repeater or something of the like. But I was hoping to be able to connect an unlimited number of computers to the network, you know? Link to comment Share on other sites More sharing options...
zsakulkill Posted April 6, 2012 Author Share Posted April 6, 2012 keep in mind, the moment you put in a repeater its a one way signal, the console could receive a signal, but not send. Also, another think to keep in mind is that every computer you add to the network requires more scripting on the main server computer. I don't really see computers being used as a viable form of communication in the near future (of minecraft lol). Link to comment Share on other sites More sharing options...
Elrol_Arrowsend Posted March 20, 2013 Share Posted March 20, 2013 okay, i dont know where else to post this, so here is my problem. i am making a computer send out a rednet signal to another computer that is looping and when it gets the signal, it runs a program on a monitor, i cant get the code i have written cause it is on a server but basicly, i have a login system and after any user logs in it opens the doors, turns on the lights and sends a signal to run the monitor, everything works except the rednet signal gets lost, the two computers are less then 10 blocks away, and i cant figure out the problem Link to comment Share on other sites More sharing options...
Elrol_Arrowsend Posted March 20, 2013 Share Posted March 20, 2013 i got the codes,, here they are Main Computer term.clear() term.setCursorPos(1,1) username = {'elrol_arrowsend', 'user'} password = {'ryvix', 'pass'} write('Please Enter Your Username: ') user = read() write('Please Enter Your TZO Password: ') pass = read() for i=1, #username do if user == username then if pass == password then access = true end end end if access == true then term.clear() term.setCursorPos(1,1) print('Logging in.......') sleep(2) term.clear() term.setCursorPos(1,1) print('Welcome '..user) rs.setOutput('top', true) rs.setOutput('right', true) rs.setOutput('left', true) rednet.open('back') rednet.announce() sleep(10) rs.setOutput('right', false) rs.setOutput('top', false) else print('Begone Intruder') sleep(2) os.shutdown() end Second Computer(runs the monitor) startup rednet.open('top') repeat local event, p1, p2, p3 = os.pullEvent() if event=='redset_message' then shell.run('monitor', 'right', 'rank') end until event=='char' and p1=='x' rank print('this should work') Link to comment Share on other sites More sharing options...
