#165186 OpenPeripherals Glasses attempt to index ?

Posted by Scarjit on 17 February 2014 - 04:06 PM in Ask a Pro

Have rescripted it. New working code for the server is:
local bridge = peripheral.wrap("right")
rednet.open("top")
bridge.clear()
width = 200
x = 0
capacity = 80000000
amount = 0
msg = ""
message = ""
value = 0
mfsu0e = 1
mfsu2e = 1
local storageUnits = {
   {
		 ["id"] = "mfsu_0",
		 ["name"] = "Main Energy"
   }
}
local offset = 0
for key, storageUnit in pairs(storageUnits) do
  pxOffset = offset * 20
  storageUnit["label"] = bridge.addText(4, 4 + pxOffset, storageUnit["name"], 0x000000)
  storageUnit["bar"] = bridge.addBox(4, 14 + pxOffset, 0, 5, 0xCC0000, 0.9)
--  storageUnit["bar"].setZIndex(2)
  storageUnit["bg"] = bridge.addBox(4, 14 + pxOffset, width, 5, 0x000000, 0.5)
  offset = offset + 1
end
while true do
local senderID, message, distance = rednet.receive()
x = message:find("x")
x = x+1
msg = message:sub(x)
value = tonumber(string.sub(message, 1, x-2))
if msg == "mfsu_0" then do
  mfsu0e = value
  amount = mfsu0e+mfsu2e
  end
end
if msg == "mfsu_2" then do
  mfsu2e = value
  amount = mfsu2e+mfsu0e
  end
end
  for i=#storageUnits,1,-1 do
	    widht = 200
	    storageUnit = storageUnits[i]
		  storageUnit["bar"].setWidth(width / capacity * amount)
		  write("W"..tostring(widht))
		  write("C"..tostring(capacity))
		  write("A"..tostring(amount))
	    end
  end



#165054 OpenPeripherals Glasses attempt to index ?

Hi iv wrote an little script wich should monitor some Mfsu's using OpenPeripheral + Rednet.
Server Code:
m = peripheral.wrap("top")
bridge = peripheral.wrap("right")
rednet.open("top")
mfsu_0e = 0
mfsu_2e = 0
Cy = 1
--Mikees script
bridge.clear()
width = 200
local storageUnits = {
   {
		 ["id"] = "mfsu_Main",
		 ["name"] = "Main Power"
   }
}
local offset = 0
for key, storageUnit in pairs(storageUnits) do
  pxOffset = offset * 20
  storageUnit["label"] = bridge.addText(4, 4 + pxOffset, storageUnit["name"], 0x000000)
  storageUnit["bar"] = bridge.addBox(4, 14 + pxOffset, 0, 5, 0xCC0000, 0.9)
--  storageUnit["bar"].setZIndex(2)
  storageUnit["bg"] = bridge.addBox(4, 14 + pxOffset, width, 5, 0x000000, 0.5)
  offset = offset + 1
end
--Mikees script end
while true do
  local senderID, message, distance = rednet.receive()
  x = message:find("x")
  x = x+1
  msg = message:sub(x)
  value = string.sub(message, 1, x-2)
  write(msg..": "..value)

	if msg == mfsu_0 then do
	  mfsu_0e = value
	  end
	end
	if msg == mfsu_2 then do
	  mfsu_2e = value
	  end
	end
storageUnit = mfsu_Main
capacity = 80000000
amount = mfsu_0e+mfsu_2e
barwidht = width / capacity * amount
write(mfsu_0e)
storageUnit["bar"].setWidth(barwidht)

end
Client Code:
m = peripheral.wrap("top")
rednet.open("top")
mfsu0 = peripheral.wrap('mfsu_0')
mfsu2 = peripheral.wrap('mfsu_2')
while true do
-- MFSU_0
amount = mfsu0.getEUStored()
rednet.broadcast(amount.."xmfsu_0")
write(amount)
-- MFSU_2
amount = mfsu2.getEUStored()
rednet.broadcast(amount.."xmfsu_2")
write(amount)
-- Other Funktions
os.sleep(10)
term.clear()
term.setCursorPos(1,1)
end
The Clients sends strings like 40000000xmfsu_0
The server should decode them in to:
mfsu_0 (id of the mfsu) and 40000000 (actual energy)
Then he should save 40000000 to mfsu_0e
The last Part is for changing the bar on the glasses.
amount = mfsu_0e+mfsu_2e is because i have 2 msfu's that i want to combine.
