Isn't it possible to use a file reader or writer on the webside? My game "Call of Worms" just doesn't start on the webside. If I run it on my computer it works perfectly. In the stack trace there it says that there is a NullPointerException when I try to use a fileReader in the world consructor. Any ideas why this doesn't work and how I can fix it?

Writing to files is not allowed on the site for security reasons. An exception to this is the UserInfo class data storage provided in Greenfoot 2.2.0+ which is limited to one score, ten integers and five Strings of fifty characters each. Reading files within your scenario is allowed, however. Make sure that your path/names are based on current directory location and that the file is within the scenario folder

Ok for security reasons that sounds reasonable. Then I have to delete this in the upload version of my game. Thank you for the reply.
