Some strange bug

Hello,so i just recently started developing in java.As i am not very advanced i decided to follow a tutorial for my first game,i found some on youtube and picked this one http://www.youtube.com/watch?v=JHxtxfUU5Is watched the first part everything went nice then on the second part i got to the part where you animate your character(Around minute 20-22).I managed to animate my character while he is walking right but when i press the A button to make him walk left he totally disappears ;/ i rechecked my code and everything seems fine.Any idea why i am getting this error ?

Well I am sure your code is perfect, I mean after all you rechecked it… and it seemed fine right? No need to show us your code or anything because the problem can’t possibly be there. Unfortunately, no I haven’t the faintest glimpse of a shadow of what might eventually become a hint of an idea on why your getting this error. Good luck debugging though!

I can telepathically tell what your problem is…one sec…sensing…hmm seems the weather is obstructing my powers. You gotta give us more information manually, OP.

Comeon fellas, he a JGO visitor, let’s put our best foot forward.
NLNP: it would be helpful if you could post some of your code here. If it’s extraordinarily long then maybe just the piece that’s likely to apply.

Starting with this kind of attitude tends to stay consistent, as you can see from some of the other members on this forum.

For this kind of topic, that was my best-foot-forward, I suppressed my first reaction! ;D
