So I'm attempting to use computercraft to run a large system. The idea is that while a lever is on, it will output power to another line, and if the lever is off, it won't.

Also I plan to have an 'interrupt' command that will -temporarily- disable things, but resume them later... but I haven't got that far yet. Right now i'm still trying to get the first half to run.

function clear()
term.clear()
term.setCursorPos(1,1)
end

while true do
clear()
local event, param1 = os.pullevent("redstone")
local redState=rs.testBundledInput("bottom", colors.white)
if redState then
redstone.setBundledOutput("bottom", colors.red)
else
redstone.setBundledOutput("bottom", 0)
end
end


that's as far as I got. But every time I run it I get an error stating that: "Bios:206: [string "shield"]:14 ')' expected.


Help... I'm new to lua!

local redState=rs.testBundledInput("bottom", color.white)

needs colors not color

[Tassyr]

Fixed that- that's an error in my reproduced code, not the actual code in tekkit. Still has the error. XP

This:

local event, param1 = os.pullevent("redstone")

--should be

local event, param1 = os.pullEvent("redstone")

I don't see anything else wrong with what you have posted.

[Tassyr]

Corrected that- it still throws up an 'expected )' error about

redstone.setBundledOutput("bottom", 0)

But that's a standard code... I used it in another computer on the same map! Did I fry something in minecraft itself?

[Luanub]

Yeah that should work. I'll be to where I can play with it here shortly.

Go through and take a close look at it, make sure you don't have a period instead of comma or something like that.

[Tassyr]

That was it. I had a period in place of a comma x.x thanks for helping me out- you're awesome!

Since you seem to be in the knowhow, however... how would I make an 'interrupt' where I could say, tap a button, and have it break the output for a few seconds...?

Just remove you're event filter and use the key events.

while true do
clear()
local event, param1 = os.pullEvent()
if event == "redstone" then
  local redState=rs.testBundledInput("bottom", colors.white)
  if redState then
	redstone.setBundledOutput("bottom", colors.red)
  else
	redstone.setBundledOutput("bottom", 0)
  end
elseif event == "key" then
  if param1 == 16 then -- q was pressed can change to what key you want or just remove so any key will work
   sleep(5) -- change the sleep to what you want it to do
  end
end
end

Here is a link to the key codes in case you do not know what they are: http://www.minecraft.../wiki/Key_Codes

er, sorry I wasn't clear- I meant a -redstone- button specifically, instead. >.< and how would a single 'wait' deactivate things temporarily? o.o

[Luanub]

What exactly are you wanting to deactivate? Turn off all of the bundled output?

And to pick up a signal from a button/lever/etc... leave your os.pullEvent() with the redstone filter just add an other if statement to check to see if it is getting a redstone signal to the side that you have the button wired up to.

local event,param1 = os.pullEvent("redstone")
local redState=rs.testBundledInput("bottom", colors.white)
if redState then
  redstone.setBundledOutput("bottom", colors.red)
else
  redstone.setBundledOutput("bottom", 0)
end
if rs.getInput("change to your side") then
  --to deactivate the bundled
  local wasOn = rs.getBundledInput("bottom")
  rs.setBundledOutput("bottom", 0)
  os.pullEvent("key") -- will wait for a key press, change to what you want sleep/redstone signal etc..
  rs.setBundledOutput("bottom", wasOn)
end

[Tassyr]

aright, so here's exactly what I'm doing. I've set up a shield generator that runs if a lever inside it is on, with a small delay in case anyone needs to get out before it goes up/etc. I've also given a few people remote redstone controls, so they can deactivate it and slip inside should they somehow be trapped OUTSIDE.

I've wired the 'main' lever to white, the output to the shield to red, and the 'remote' redstone to black.

basically what I want is that if you get a signal from black it temporarily cuts the power if the shield is on. sort of a five-to-ten second 'interrupt.'

[Luanub]

Ahh very simple here you go:

while true do
clear()
local event,param1 = os.pullEvent("redstone")
local redState=rs.testBundledInput("bottom", colors.white)
if redState then
  redstone.setBundledOutput("bottom", colors.red)
else
  redstone.setBundledOutput("bottom", 0)
end
if rs.testBundledInput("bottom", colors.black) then

  rs.setBundledOutput("bottom", 0)
  sleep(5) --adjust accordingly
  if redState then
    rs.setBundledOutput("bottom", colors.red)
  end
end
end

Aha, thanks. Will test this tomorrow morning />

[Tassyr]

It worked, thanks! />
