Hi,  
I seem to be running into a lot of subtle bugs lately. This one is  
stranger than most.

def shake  
@engine.inject do  
@engine.run do |key|  
@engine.sleepForTime(key, 0.6) do |timePassed, timeSlept|  
@x = (rand_2-1)_(1-timeSlept)_30  
 @y = (rand_2-1)\*(1-timeSlept)\*30  
end  
end  
end  
\<— This empty line needs to be here.  
end

My program gives me wrong results when the empty line is not included.  
It doesn’t throw any syntax error. It just gives me wrong results,  
leaving me completely befuddled.  
Any guesses on what might be happening?

double check line endings maybe they’re messed?

Yup that was the problem. I moved the file over from a Linux system, and  
the line endings got corrupted.

Thanks Roger.
