Java Side Scroller
Hey can anyone please help me out? I'm trying to create a side scroller game but having some difficulties with the ribbons and making it appear as though the my character is moving. I created this code below but I cannot test if the ribbons work because when I click compile it says there aren't any errors but it won't let me run it. Can anyone please give me some of your expertise on this? Thanks in advance.
