 Event rednet_message | |
| Fired when any rednet.send()'d message arrives through an open modem. | |
| Returned Object 1 | The computer ID of the sender (see os.getComputerID()). |
| Returned Object 2 | The message. Functions / coroutines sent are converted to nil. Prior to about CC 1.53, so were tables, which required use of textutils.serialize() to transmit. |
| Returned Object 3 | The protocol used, or nil if none was specified. Prior to CC 1.6, this was the distance (in blocks) between the computers. |
 Example | |
| Prints a message | |
| Code |
while true do
event, senderId, message, distance = os.pullEvent("rednet_message")
print( "Computer: "..senderId.." sent a message: "..message.." from "..distance.." blocks away!" )
end
|
| Example | |
| Ignores messages from any computer other than the one with id 5 | |
| Code |
while true do
event, senderId, message, distance = os.pullEvent("rednet_message")
if senderId == 5 then
print("Got a message from the boss saying: "..message)
end
