Problem with Rednet

while true do
local senderId, message, distance = rednet.message()
if y == "b1o" then
redstone.setBundledOutput("bottom", colors.orange)
os.reboot()
end
elseif message == "b2o" then
redstone.setBundledOutput("bottom", colors.blue)
os.reboot()
end
elseif message == "b3o" then
redstone.setBundledOutput("bottom", colors.white)
os.reboot()
end
elseif message == "b4o" then
redstone.setBundledOutput("bottom", colors.magenta)
os.reboot()
end
elseif message == "bo" then
redstone.setBundledOutput("bottom", colors.orange+colors.blue+colors.white+colors.magenta)
os.reboot()
end
elseif message == "bc" then
redstone.setBundledOutput("bottom", 0)
os.reboot()
end
end

What is my mistake?

PS: Sorry for the few informations, my english is very bad …

Remove all of the os.reboot calls. When the computer reboots, all redstone outputs are turned off.

rednet.message() is not a valid function. In the future you should post the actual error produced.

I´am very sorry this is the error:

bios:338: [string "tueren"]:6: ´end´ expected (to close ´while´ at line 1)

Your ifs are incorrect. You have if end elseif end elseif end. You need to remove most of those ends, so you have if elseif elseif end. One end for the entire if, not one for each part of it.

That's because you've inserted end's before your elseif's. You don't need them, the structure is "if conditional then codeblock elseif conditional then codeblock else codeblock end".

If you've changed your code, you need to post the most recent version.

while true do
if rednet.message() == "b1o" then
redstone.setBundledOutput("bottom", colors.orange)
elseif rednet.message() == "b2o" then
redstone.setBundledOutput("bottom", colors.blue)
elseif rednet.message() == "b3o" then
redstone.setBundledOutput("bottom", colors.white)
elseif rednet.message() == "b4o" then
redstone.setBundledOutput("bottom", colors.magenta)
elseif rednet.message() == "bo" then
redstone.setBundledOutput("bottom", colors.orange+colors.blue+colors.white+colors.magenta)
elseif rednet.message() == "bc" then
redstone.setBundledOutput("bottom", 0)
end

Thats the code …

bios:338: [string "tueren"]:14: ´end´ expected (to close ´while´ at line 1)

Thats the error …

rednet.message()

does not exists, you're looking for

id, msg = rednet.receive()

then in each comparison do:

if msg == "b1o" then
elseif msg == "b2o" then
--etc
end

Also open your modem,

rednet.open("side") -- ie "left"

Also, your if is now correct, but you do need a second end at the very end to close the while loop.

Thank you all!

/close

PostScriptum: Thats the code

while true do
id, msg = rednet.receive()
if msg == "b1o" then
redstone.setBundledOutput("bottom", colors.orange)
elseif msg == "b2o" then
redstone.setBundledOutput("bottom", colors.blue)
elseif msg == "b3o" then
redstone.setBundledOutput("bottom", colors.white)
elseif msg == "b4o" then
redstone.setBundledOutput("bottom", colors.magenta)
elseif msg == "bo" then
redstone.setBundledOutput("bottom", colors.orange+colors.blue+colors.white+colors.magenta)
elseif msg == "bc" then
redstone.setBundledOutput("bottom", 0)
end
end
