Theeboris: /* Getting started */

Rednet is an API that allows computers and turtles interact with each other wirelessly.

== Getting started ==

* Attach a [[Modem|wireless modem]] to your [[Console|computer]].
{{Crafting grid
|A1=stone |B1=stone |C1=stone
|A2=stone |B2=redstone_torch |C2=stone
|A3=stone |B3=stone |C3=stone
|Output=modem
}}

A modem is made using 8 stone blocks surrounding a redstone torch.

== Rednet scripts ==
Rednet uses several methods to interact with other computers.

Here is a basic program that runs most of them. It requires 2 PCs.

PC1
[[Rednet_(API)|rednet]].[[Rednet.open|open]]("right") --enable the modem attached to the right side of the PC
[[Rednet_(API)|rednet]].[[Rednet.broadcast|broadcast]]("Hello world") --send "Hello world" over rednet to all PCs in range
[[print]]("PC1 - Hello world")
id,message = [[Rednet_(API)|rednet]].[[Rednet.receive|receive]]() --wait until something is received over rednet
if id == 2 and message == "Hello from pc2" then
[[write]]("PC2 -")
[[print]](message)
[[Rednet_(API)|rednet]].[[Rednet.send|send]](2,"How are you") --Send a message only to the PC with ID 2
[[print]]("PC1 - How are you")
id,message = [[Rednet_(API)|rednet]].[[Rednet.receive|receive]](10) --Wait until a message arrives or 10 seconds pass
if message == "Fine thanks" then
[[print]]("PC2 - Fine thanks")
end
end
[[print]]("disconnecting")
[[Rednet_(API)|rednet]].[[Rednet.close|close]]("right") --disable modem on the right side of the PC

PC2
[[Rednet_(API)|rednet]].[[Rednet.open|open]]("right") --enable modem on the right side of the PC
id,message = [[Rednet_(API)|rednet]].[[Rednet.receive|receive]]() --wait until a mesage is received
if id == 1 and message == "Hello world" then
[[Rednet_(API)|rednet]].[[Rednet.send|send]](1,"Hello from pc2") -- send a message to only the PC with ID 1
id,message = [[Rednet_(API)|rednet]].[[Rednet.receive|receive]]() -- Wait until a message is received
if message == "How are you" then
[[Rednet_(API)|rednet]].[[Rednet.broadcast|broadcast]]("Fine thanks") -- Send to all PCs in range
end
end
[[Rednet_(API)|rednet]].[[Rednet.close|close]]("right") -- disable modem on the right side of the PC

Open PC2 first after that open PC1 and then run the program
