IC2 reactor controller

ive been thinking of taking red power out of the equation with my first program.

by taking it out i mean have the computer control the timer with sleep, but im running into a problem. im having bad luck with the if/then statements, it keeps saying <EOF> error , or expecting end at line 2.

the goal is to have 1 input 1 output:
the input will be triggered from a thermal sensor block, and then come into the computer telling it to set the output to the reactor on then wait 45 seconds with sleep. then turn off, else repeat the application

here the script

local cool = "back"
local control = "right"
function cool()
if rs.getInput(cool) then
rs.setOutput(control, true)
sleep(45)
end
else
Cool()

the end comes after the code of else

if <condition> then
  <code>
else
  <code>
end

okay thank you ill try it

still an error

Well whats your new code?

local cool = "back"
local control = "right"
function cool()
if rs.getInput(cool) then
rs.setOutput(control, true)
sleep(45)
rs.setOuput(control, false)
else
end
Cool()

uh well I don't know what exactly you are trying to do there
Looks like you're also trying to recursively call your function which will crash eventually
use timers instead

did you read my description on my first post?

oh yeah you only need to wait for the redstone event in a while loop then

or not quite sure there.. why "repeat the application"?

i repeat it so when it heats up again and the reactor hits 1000 temp. then it does it again

You should use the code blocks to preserve code formatting when posting your code, it makes it a lot easier to read. The problem with your code is you are missing and "end" at the end. In lua, there are a number of calls that work as brackets. To make things easier, we use indentation to help remember where we are missing an end. Here are some examples:

function callme(parameters)
  <code>
end

for i,j in ipairs(list) do
  <code>
end

while <condition> do
  <code>
end

if <condition> then
  <code>
end

if <condition> then
  <code>
elseif <condition> then
  <code>
else
  <code>
end

If you put any of these inside each other, each must be closed off by an end. Again, indentation helps you keep track of where you were, since you cannot go up an indentation level without using an end statement. For example:

local cool = "back"
local control = "right"
while true do
  if rs.getInput(cool) then
	rs.setOutput(control, true)
	sleep(45)
	rs.setOutput(control, false)
  else
	sleep(1)
  end
end

You will notice that each time I go in a level, I come back out later. In your code, your function and your if statement go in one level, but you only have one end statement, so the lua interpreter hits the end of the file and is still expecting another end, and thus gives an error.

Also, that last example should be a working version of your code. Cheers!

Lua is case sensitive. Your function name is cool but your calling Cool().

Your also using cool as a var and a function name, you can't do both.

Chaning the function name to Cool will fix both issues.

Try this.

local cool = "back"
local control = "right"
function cool()
  if rs.getInput(cool) then
	rs.setOutput(control, true)
	sleep(45)
	rs.setOuput(control, false)
  end
  cool()
end

Or this.

local cool = "back"
local control = "right"
repeat
  if rs.getInput(cool) then
	rs.setOutput(control, true)
	sleep(45)
	rs.setOuput(control, false)
until false

local cool = "back"
local control = "right"
while true do
os.pullEvent("redstone")
if rs.getInput(cool) then
rs.setOutput(control, true)
sleep(45)
rs.setOutput(control, false)
end
end

This would be better than constantly checking for input, just wait for it.
