Rednet send message

Im trying to send a message with rednet to another computer but it dosent seem to want to work.

im using open peripherals to get a signal from a quarry so that i can tell if its active or not and sending that through rednet to a computer that connects to a monitor and prints the true false message that should be being sent but it dosent seem to work

here is the code for computer hooked to quarry sending the message

rednet.open("right")
net = peripheral.wrap("back")

net = net.callRemote("quarry_1","isActive")
while true do
rednet.send(13,net)
sleep(0.5)
end

and here is the code for the second computer receiving the message and writing it to the screen

rednet.open("left")
local monitor = peripheral.wrap("top")

while true do
id,message = rednet.receive()

monitor.write(message)
sleep(0.5)
end

if anyone can tell me what im doing wrong id be very appriciative thanks :D/>

rednet.send expects a string for the message, and you're giving it a boolean. Instead, you could do something like this:

rednet.send(13, net and "1" or "0")

That will send "1" if net is true or "0" if net is false. On the other side, you just check for "1" or "0". You can of course use whatever strings you want.

i got it to work but then i realized you cant send a rednet message through different worlds and that ruined the whole thing enles there is a way and i dont know how

i think there is a 50 block range on renet as well…

You could do it a few other ways, maybe an enderchest and get the turtle to get item stack, if it is one then make it emit a signal, if it isn't then stop it.

You could also do it, using a wired buildcraft structure pipe with a logical-gate, checking for "work scheduled - work done". But the traveling time for the signal gets long at long distances. Also put a gate at the receiver computer that emits a redstone signal when receiving a pipewire signal. Then you check via rs.getInput at the computer.
