Sending multiple Variables in the network

[Zeldri 0]

Is that possible to send multiple variables with comp.modem.send() ?

Because I want to send like that :

function sendMsg(type,data,data2,data3)
    m.open(118)
    m.send(address,118,type,data,data2,data3)
end

And i call the function like that :

sendMsg("ReacteurInfo",pct(),cube.getEnergy(),cube.getMaxEnergy())

The problem is that the second variable isn't being send ( the third too ) same if i put cube.getEnergy() before, (in this case only cube.getEnergy() is being send and vise-versa) But when I want to send 2 or 3 string it's working perfectly 

sendMsg("ReacteurInfo","test1","test2","test3")

From looking at the modem component API you should be able to send up to 8 basic datums in each message.  From what I can see in your example It should work fine sending. Could you post your receiving code? The 'modem_message' event has 5 return values before the data you've sent.

local _event, localAddress, remoteAddress, portNumber, distance, sentData1, sentData2, sentData3, sentData4 = event.pull("modem_message")

Ok so I dont know why but now I receive all the data but the problem is that I receive nil when I'm using it on my program

But On my program i got a nil value

There is my code

local comp = require("component")
local term = require("term")
local colors = require("colors")
local event = require("event")
local gpu = comp.gpu
local m = comp.modem
gpu.setResolution(100,31)
local w,h = gpu.getResolution()
 
os.sleep(1)
m.open(118)
m.broadcast(118)
while true do
  gpu.setBackground(0x202020)
  gpu.fill(1,1, w, h, " ")
  gpu.setBackground(0x606060)
  gpu.fill(1, 1, 2, h, " ")
  gpu.fill(1, 1, w, 1, " ")
  gpu.fill(w-1, 1, 2, h, " ")
  gpu.fill(1, h, w, 1, " ")
  gpu.fill(w/2, 1, 2, h, " ")
  gpu.fill(1, 1, w, 3, " ")
  gpu.set(w/4-4, 2,"Réacteur")
  gpu.set((w/2+w/4)-4, 2, "Crystaux")
  os.sleep(1)
local  evt,ladd,radd,dis,port,type,data1,data2,data3 = event.pull("modem_message")
  if type == "ReacteurInfo" then
    data1 = pct
    data2 = nrj
    data3 = nrjMax
    gpu.set(4,8,nrj)
    gpu.set(4,10,nrjMax)
    gpu.set(4,12,pct)
  end
  gpu.setBackground(0x000000)
end

I'm pretty sure your problem is here..

    data1 = pct -- pct is nil
    data2 = nrj -- nrj is nil
    data3 = nrjMax -- nrjMax is nil
    gpu.set(4,8,nrj) -- This is where the error comes from. "Bad Argument #3 (string expected, got nil.)"...
    gpu.set(4,10,nrjMax) -- so on..
    gpu.set(4,12,pct) -- and so on..

Nowhere in the above code you supplied did you define the values of pct, nrj, or nrjMax. So, they are nil.
