Trying to make an "advanced timer" with args.

SOLVED!! Thanks to Woodyr!

Hello out there Pro's!

im trying to make a timer, and i know its almost is working tho i've hit the wall with it to start..
"test:13: attempt to concentrate nil and string"

Code:

local args = {...}
local delay = tonumber(args[2])
local side = args[3]

if args[1] == nil or args[1] == "help" then
   print("test <time> <side>")
else
   while true do
	 shell.run("redpulse", side, "1")
	  sleep(delay)
end

EDIT: when i change "args[2]" to 3 and the args[3]" to 2 it says "no such program :S

I cant spot what im doing wrong :/

You never ended the while true do loop, thats something to start off with.

If you give your turtle a command line it reads it as following:

<program name> <1st argument> <2nd argument> etc..

So what your program does is pretty much skip the first argument, read the second (the side) and attempt to convert it to a number. Then it reads a 3rd argument, which there isn't.

So the fix is:

local args = {...}
local delay = tonumber(args[1])
local side = args[2]

I think that should work :)/>

PS: if you have a different function for the first argument and knew what I posted already: Ignore my post :P/>

What you just said, i've allready did, but i'd like to when you type "test help" it will print how it wants you to do it, the other thing works Perfectly! that allready worked for me :)/>

its the help thingy thats gives me the issue :/

local args = {...}
if args[1] == nil or args[1] == "help" then
   print("test <time> <side>")
   return
else
	local delay = tonumber(args[1])
	local side = args[2]
	while true do
		 shell.run("redpulse", side, "1")
		 sleep(delay)
	end
end

Something like that may do the trick (haven't tested it, on my mobile phone :P/>)

Will test it soon :)/>

Wooo! it works!

pastebin get DSBV2QYt Timer

– It works!!! THanks alot woodyr! :D/>

I simply made it break the program when it has no arguments or when it is "help", if its something else, itll do the timer stuff :P/>

"return" - just return to the code before the IF loop? or does it just say, we skip this part and go on! =P

"return" ends the program
