Rednet opener! (Super simple!)

for _, side in pairs(redstone.getSides()) do
		rednet.open(side)
end

Thanks to Espen for the redstone.getSides() method that I never noticed

Don't go thrashing because it's 3 lines of code. I made it super simple for people that are beginners with LUA.

You could also replace your fixed table with the built-in getSides() function of the redstone api to make it both shorter and future-proof:

for _, side in pairs(redstone.getSides()) do
	rednet.open(side)
end

Cheers :P/>/>

P.S.: In case someone learning Lua wonders about the _ (underscore):
In this case I've used it as the variable for the keys which in this case are of no need, because we only need the values ('side' variable).
It's commonly used to denote that either the keys or the values are of no need.

Thanks, but it was so it would be compatible for Tekkit cause my friends and I play on it :P/>/>

Tekkit doesn't have rs.getSides()? Not that I'm super dependent on it or anything, but that's kinda weird.

You also want to make it a function and return true if a modem was opened or false if no modem was found.

local function opnmdm()
for i,v in pairs(rs.getSides()) do
  if peripheral.getType(v) == "modem" then
   if not rednet.isOpen(v) then rednet.open(v) end
  return true end
end
return false end

No, I don't bother to ever use anything other than "for i,v in pairs/ipairs do … end". The i and v both get thrown away at the end of the loop anyway, and it helps me to remember never to set any variables named i or v.

I just found a ComputerCraft 1.21 on my drive and it supports getSides().
I'm not sure since when it was available, but if your Tekkit has turtles, then you should have getSides().

A possible reason for the confusion just came to mind:
If you typed "help rs" and didn't see a getSides() function, then that's because it's only listed on "help redstone", which is more up-to-date than the help-page for rs. But rs and redstone are the same API, so you should definitely have that function.^^

hehe, I just remembered (encountered while coding) the case where I have to use something other than i,v … when the for loop is inside another for loop that I need the i or v from.

Just noticed that said "redstone.getSides()"… XD

from a n00b.

Thank you so much for making this much faster and easier then going into LUA every time and telling it to open the side the modem is on.
now just run a program and done.

You're so very welcome :P/>/>

It's not a program, it's not even a function, really. It's just a couple of lines you can use to open a modem to stick in a program that uses a modem. I prefer a full function so I can use the return to know whether or not there was a modem to open, but for some purposes this would be fine.

Stop thrashing kid.

This has already been made.. multiple (thousands+) times?

Seriously. Any half-decent coder could write this exact thing up in about two seconds. Get rid of this.

I don't care how many times it's been made, there is no reason for you to be a complete douche and thrash just because I'm trying to help out some people that know little to no LUA. So leave.

Have you seen any of my projects? If you're gonna be a complete douche saying that I know little to no LUA then you should back it up with some proof kid.

I'm not thrashing… It's just unnecessary. If they want to learn these methods just read any rednet code.

EDIT: Here comes Cloudy…

I know it's unnecissary, but I made it because when I sit in the ComputerCraft IRC there are like 10 people a day that say "How do you open a modem on all sides?"

Yeah…that happens. You might want to post it on a tutorials thread or something. Or not.

I am not trashing this program because it stinks. I'm trashing it because it's useless. Any decent program that uses rednet will incorporate this code. So, any end users will never need to manually open a modem.

This program didnt open it at all sides, the topic the first time I read it was

Rednet opener!!

code:
rednet.open("left")
print"opened!"

it needs to be at the left side

It's not a program, it's a snip-it of code for people that know little to no lua, I just get tired of people spamming OPs in the IRC.

For one, this is not a program, for two, this snip-it of code never once said rednet.open("left") print"opened!".
Also, the post title is "Rednet opener! (Super simple!)" so you're reading a different post.

Locked thread, no offense stilldabomb, but this asks for hate.

Edit: hmm nvm, moved to tutorials instead.

Yeah, I thought about getting it moved to tutorials a while ago…

It's 3 lines of code, you cant act like you're the only one that coded that.

I never said I did, I'm saying, the amount of people that are like "I don't want to type this! It's too long!" when it's really only 3 lines.
