-- Script B+: Listen for "SMiner" broadcasts and watch shield state changes

-- 1) Find peripherals
local speaker = peripheral.find("warpdriveSpeaker")
local shield  = peripheral.find("warpdriveForceFieldProjector")
assert(shield, "ForceFieldProjector not found!")

-- 2) Open all modems for rednet
for _, side in ipairs(peripheral.getNames()) do
  if peripheral.getType(side) == "modem" then
    rednet.open(side)
  end
end

-- 3) Speak helper
local function trySpeak(msg)
  if speaker then speaker.speak(msg) end
end


-- 5) Rednet listener coroutine
local function rednetListener()
  while true do
    local senderID, message = rednet.receive("SMiner")
    if message == "check" then
      local enabled = shield.enable()  -- query current state
      if enabled then
        print("Received check → Shield currently ENABLED")
        trySpeak("Shield is enabled")
        rednet.broadcast("StatON", "SMiner")
      else
        print("Received check → Shield currently DISABLED")
        trySpeak("Shield is disabled")
        rednet.broadcast("StatOFF", "SMiner")
      end
    end
  end
end

-- 6) Shield-state monitor coroutine
local function stateMonitor()
  local prevEnabled = shield.enable()
  while true do
    local enabled = shield.enable()
    if enabled ~= prevEnabled then
      if enabled then
        print("Shield state changed → ENABLED")
        trySpeak("Shield enabled")
        rednet.broadcast("StatON", "SMiner")
      else
        print("Shield state changed → DISABLED")
        trySpeak("Shield disabled")
        rednet.broadcast("StatOFF", "SMiner")
      end
      prevEnabled = enabled
    end
    os.sleep(0.5)
  end
end

-- 7) Run both loops in parallel
parallel.waitForAny(rednetListener, stateMonitor)
