Topic hijac question about APIs.

Is there a way to add api's to a server? Would it have to be a resource pack and if so, would I need to constantly unzip it to modify the code in it or can it be a regular folder, not a .zip? I'm using ComputerCraft1.57 for minecraft 1.6.4 with the newest forge version. I haven't tried a resource pack but every time I try to unzip computercraft and get around the lua/rom mounting error, I've been unsuccessful.

Please don't hijack topics.

If you want to add an api to a specific computer, you can open <server folder>/<world folder>/computer/<id> and put it there.

Sorry, but I want the api to be accessed from more than one turtle without having to place it in each turtle individually.

How do you get multiple turtles to load an api that you made in game if it's not in the api folder?

I made an api on one turtle and I want to load it on another, how would I do that? I am using ComputerCraft 1.57 for minecraft 1.6.4.

Wow.. Nice necromancing skills :P/>
Anyway.. Are you trying to load an API from a turtle that is on another turtle? O_o
Well you need to have it on the other turtles. Maybe by letting them stand next to a disk drive and let them copy it from there, Or simply send the file through rednet, Or even better.. Pastebin :P/>

From one turtle to another, yes. Is there a way to "broadcast" an api over rednet? or better yet, broadcast the pastebin function to all turtles/computers?

Okay, Todo this you must have the turtles receiveing ofcourse.
Now here's a way todo it.

Transmitter

term.clear()
term.setCursorPos(1,1)
write("File: ")
local filename = read()

local code
if fs.exists(filename) then
    local f = fs.open(filename, "r")
    code = f.readAll()
    f.close()
    print("Broadcasting code!")
    rednet.broadcast(code)
else
    print("File didn't exist!")
end

Receiver

local id, code = rednet.receive()
local file = fs.open("YourFile", "w")
file.write(code)
file.close()

end 

Receiver

local file = fs.open("YourFile", "w") 
file.write(code) 
file.close() 

In the receiver, why is there a "w" standalone second parameter for fs.open? Also, sorry to bug you about this, but could you go through the code and explain it a little? I understand most of it… I just get a little lost while going through it. Thank you.

Moved the whole message over so people can see what I'm answering. This guy should get an award for hijacking.

The "w" tells the FS API to open the file in write mode. And of course, the same thing happens in the transmitter on line 8, but fs.open gets an "r" there, which means read mode.

When you fs.open() a file, you need to specify whether you intend to read data from it, or write data to it.

Edit: Ninja'd!

Nah. If there was any kind of call, you'd see at least two parentheses. local is a keyword in Lua that *surprise* localizes variables. That means when you localize a variable inside a block (will explain that later), you cannot access that variable once you get out of the block.

local x = 8 -- x is localized here, in the body of the program
if true then -- makes no sense, but it is a block nonetheless
    local y = 9 -- y is localized here, in the body of the IF block
    print(x) -- prints 8
    print(y) -- prints 9
end
print(x) -- prints 8 - we are still in the program, we are still able to access x
print(y) -- prints nothing - we're out of the IF block - y has got garbagecollected 2 lines ago, and now it isn't set at all (nil)

Blocks are those things enclosed by then and do (which start blocks), until and end (which end blocks). The so called "indentation" is about making these blocks more visible (eg. by using tabs or four (or whatever number of) spaces).

So:

local id, code

is like saying "hey, Lua, localize id and code here".

Threads merged. What a mess. Ninjawhatever, you really need to start one topic in Ask a Pro when you have a question instead of digging up months-old or year-old threads to post tangentially-related (at best) questions on them.
