emeralds

---Simple little program to automate my Minecraft emerald farm.
---
---Basic idea: I have an infinite villager breeder feeding into a
---smeltery (yes, I'm a bad, bad man). This script is for the computer
---to monitor the smeltery and trigger the drain whenever there's more than
---one emerald in there. More than one so that the smeltery doesn't end up
---empty and stop killing villagers.

function alarm()
    allGood=false
    redstone.setOutput("bottom",true)
    while not allGood do
        info=smelt.getInfo()
        allGood= (info.id==27)
    end
    redstone.setOutput("bottom",false)
end

smelt=peripheral.wrap("right")

alarm()

while true do
    info=smelt.getInfo()
 print(info.id)
    if not (info.id==27) then
        alarm()
    elseif info.amount > 640 then
        redstone.setOutput("back",true)
        sleep(1)
        redstone.setOutput("back",false)
    end
    sleep(30)
end
