I have recently started using construct 2. I have my background 1 and main layout how they should be, with my sprites on the layout. I have made sure the correct layout/background is locked and the main one is not. When I click run to test my game, all I see is just the original background. I have been watching walkthroughs on this and it appears I am doing everything right. What should I do now since I can't even see my sprites when I press run??
