Yes,I know that...I was trying to make a better one,for exemple: When you turn on until the last green bar,when you press to turn off the bars,turn off the last green instead the red bars, then the yellow bars,theeeeeeen turn off the green... But it's reaaaaally hard to do. :P If you know how,please tell me. Sorry for bad english.
@victorherbst No, I have no idea at all. XD That save is pretty clever though. Interesting concept. I will probably have a fiddle with it, but I doubt I could do any better. =D
EDIT: Got this to work for an engine, so the base one stays on and only the second one goes on and off, without going through the green!
