The rednet_message event is fired when a message is sent over Rednet.
This event is usually handled by rednet.receive, but it can also be pulled manually.
rednet_message events are sent by rednet.run in the top-level coroutine in response to modem_message events. A rednet_message event is always preceded by a modem_message event. They are generated inside CraftOS rather than being sent by the ComputerCraft machine.
- string: The event name.
- number: The ID of the sending computer.
- any: The message sent.
- string|nil: The protocol of the message, if provided.
Prints a message when one is sent:
while true do local event, sender, message, protocol = os.pullEvent("rednet_message") if protocol ~= nil then print("Received message from " .. sender .. " with protocol " .. protocol .. " and message " .. tostring(message)) else print("Received message from " .. sender .. " with message " .. tostring(message)) end end
