Lighthouse Sequence

I had this working, and it sort of works if I get rid of the Else part. It runs a lighthouse off two bundled cables. I have tried to set it to turn off during the day. I keep getting errors like 'end' expected and 'eof' expected. I have tried several rearrangements, but must be missing one.

function BundleRight()
rs.setBundledOutput("right", colors.combine( 0, alpha))
sleep(1.5)
alpha = alpha*2
end
function BundleBack()
rs.setBundledBack("back" , colors.combine(0, alpha))
sleep(1.5)
alpha = alpha*2
end
while rs.getInput("top)~=true do
alpha = 1
rs.setBundledOutput("right", colors.combine(0, 0))
rs.setBundledOutput("back", colors.combine(0, 0))
for count=1,9 do
  BundleRight()
end
rs.setBundledOutput("right", colors.combine(0, 0))
alpha = 1
for count=1,9 do
  BundleBack()
end
else
rs.setBundledOutput("right", colors.combine(0, 0))
rs.setBundledOutput("back", colors.combine(0, 0))
sleep(30)
end

Any help is appreciated.

Currently, this is your code, but I've taken all the shit from the middle.

while rs.getInput("top") ~= true do -- Your code says ("top), you should close that string otherwise it will always throw an error there.

else -- As far as I'm aware, you can't actually "else" a while loop.

end

while rs.getInput("top)~=true do

to

while rs.getInput("top") ~= true do

– You forgot the last "

The else on the 5 last line, what if does it correspond to?

EDIT: Ninja'd

That would be the issue, I was trying to use an else with while. Thanks for the help.

*edit* Still working out how to get the if statement to do what I want it to do.

If you need any more help, feel free to ask.

Ok. Yes.

This is the code to run the lights around the lighthouse.

alpha = 1
rs.setBundledOutput("right", colors.combine(0, 0))
rs.setBundledOutput("back", colors.combine(0, 0))
for count=1,9 do
  BundleRight()
end
rs.setBundledOutput("right", colors.combine(0, 0))
alpha = 1
for count=1,9 do
  BundleBack()
end

That works fine. I am not sure where to put the If statements around it though. I want to see if there is redstone signal from the Light Sensor is transmitting, if so I don't want to run the code. And I want it to check every 30 Seconds on that. My ideal plan was to run through the code for the lighthouse and check the sensor after a full rotation.

All you have to do is use a while true do loop with an if function to check for redstone signal.

local sLightSensor = "back" -- which ever side the redstone signal from lightsensor is coming from.

while true do
    if rs.getInput(sLightSensor) then
        print("Signal found")
        -- code if signal is found
    else
        alpha = 1
        rs.setBundledOutput("right", colors.combine(0, 0))
        rs.setBundledOutput("back", colors.combine(0, 0))
        for count=1,9 do
            BundleRight()
        end
        rs.setBundledOutput("right", colors.combine(0, 0))
        alpha = 1
        for count=1,9 do
            BundleBack()
        end
        print("Signal not found")
    end
    sleep(30)
end

Thank you, got it working by changing much of it to functions so it was easier to fix code. My issue now is startup.

I have this startup file on both the computer and a connected floppy drive

shell.run("lighthouse")

It returns the error

reboot:3: attempt to call nill

just curious, is the program actually called lighthouse, and is it on the root (as in not in a folder)?

Yes, all lowercase, and it is in the root directory.

Try,

os.run({}, "/lighthouse")

I'm not really familiar with shell.run() so I can't tell you the difference.

Also, could you please post the startup code?

That was my startup code…

It seems to work on a full server reset though, just not if I reboot

I'm a bit confused here. What doesn't work, the reboot, or the program after you reboot?

I just realized it is the reboot program that is failing. Not sure why.

Fails on the third line which is:

os.reboot()

with the error attempt to call nil

This is the default file in the rom directory, and no other files were made with the name reboot. But I don't actually need it to reboot as long as my startup file is working, which it is.

*edit* Ctrl-R works so I will just use that for testing.
