basically whenever i go to on to greenfoot i cant see any of my actors ,an the only the thing i can see is the greenfoot logo as a replacement what can i do to solve this problem?
Well, seeing the greenfoot logos is a good sign. The greenfoot logo is the default image greenfoot supplied for you actors. It at least means your project is compiling without error and your actors are being added to the world. You can right-click on your Actor subclass icons and select 'Set image ...' to change the default image for actors created from the class; or, you can add a constructor to the class code that creates a GreenfootImage to set as the image for the actors created from the class.
