when i use rednet to send messages between computers to do tasks with the starting computer using the lua command everything works as intended but when i make it a file even with the same code the 3 computer in the series sends the message but the computer receiving the message doesnt receive it although the code is the same link to video https://drive.google.com/file/d/1nwdiP9DqDxCeLzEAJdch5hoTSkd9Am1B/view?usp=sharing

I believe this is a bug in your program(s), rather than something to do with calling from lua or not. After all, rednet.send doesn't know how it's being invoked!

It's quite hard to know quite what's going wrong, without recreating your setup block-for-block. I'd recommend adding lots of print calls to your program, so you can see what code is/isn't being hit. For example, print out the value of message and messoge on the second computer.

One possible cause here is that the first computer will send "disasem" both when the redstone signal is turned on and turned off. This means messoge may be "disasem" (depending on timing), and so that second if block won't be triggered.

My assumption of your issue is that you aren't waiting for asem. You receive disasem, then only listen once for another message. If that message is not what you expect it to be, you go back to waiting for disasem.

Specifically, I am talking about this chunk here:

ido, messoge = rednet.receive()
if messoge == "asem" then
    print("recieved")
    redstone.setOutput("right", true)
end

if messoge is not asem, then it just... Does nothing. It skips over that if statement, then goes back to the very top of the loop, back to waiting for disasem again.

Recommendation: Listen for specific messages repetitively, instead of once. For example,

--- This function waits until a specific message arrives. Do note that you cannot compare tables received this way!
---@param expected_message any The message to listen for.
local function wait_for_message(expected_message)
  print("Waiting for:", expected_message)
  repeat
    local id, message = rednet.receieve()
  until message == expected_message
  print("Got:", expected_message)
end

Then, in your code, you could do something like so:

while true do
  wait_for_message("disasem") -- Waits specifically for "disasem".
  
  redstone.setOutput("right", false)
  sleep(0.2)
  rednet.send(3, "load")
  
  wait_for_message("asem") -- Waits specifically for "asem".

  redstone.setOutput("right", true)
end
