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 ?
