Functions returning nil value

Hi!

I'm having a problem I can't seem to wrap my head around.... I'm trying to use the Big Reactors Computer port, but every time I try to do something with it i.e. component.br_reactor.getEnergyStored, which reads total energy stored in the reactor, I get an error message saying:

Attempt to index 'component' (a nil value) (On line 1)

Here's the code:

power = component.br_reactor.getEnergyStored()
if power>5000000 then component.br_reactor.setActive(false) else component.br_reactor.setActive(true) end
sleep(1)

I attempt to do something(I have no idea what I'm doing), and add one line to the top.

local component = require component
power = component.br_reactor.getEnergyStored()
if power>5000000 then component.br_reactor.setActive(false) else component.br_reactor.setActive(true) end
sleep(1)

I now get the error message Syntax error near 'power'

 

The code is supposed to check if the EnergyStored is more than 500000 (half full) if it is deactivate the reactor, if not activate it.

 

Any tips will be gladly appreciated!

 

This is the first I've done within coding ever, apart from some HTML, so be gentle.

require needs the api name as String, so try this:
local component = require 'component'

I'm not sure if I need the variable or not, but I trien once without(replaceing the variable with the actual function), but that didn't work either....

Thanks man! I'm amazed that the rest of the code actually worked too, but now I have to get working on that sleep function....

you mean

local os = require("os")

os.sleep(seconds: number)?

Wow! Thanks, Michiyo. I had no idea it was that easy! =)
