A list is an object, yes; but, it is an abstract object and cannot be displayed as such. Really all you have are a bunch of String object (which also are abstract). What needs done is to create objects to draw the strings on and display them, which you can accomplish by way of a list component gui or by coding it yourself (I prefer to code things myself, as then I am not restricted in any way as to how to do things and what can be done. The drawback to this, though, is the time factor. On the plus side, however, is the experience of the journey to accomplish this task; the knowledge

You saved me again thanks :-) I dont know why I didnt try that LOL

Hello davemac thanks for your help. I found an explanation in German. See: http://www.rootz.de/2011/02/debian-6-0-squeeze-java-apps-haben-probleme-mit-netzwerkverbindungen/#more-1966 which links to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560044 it says to do sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' /etc/sysctl.d/bindv6only.conf sudo invoke-rc.d procps restart now greenfoot starts. Just to make it clear: my log starts with

I think I understand that. Thank you.

There are plenty of examples out there, see tutorial #6 for instance.

I tried it and it worked. Thanks for all your help

When you detected you 'fall off' an edge, you need to reset the world doing this: <Code Omitted>Replace 'MyWorld' by your own subclass of World.

Thanks for all of your help...everything works as intended.

Yay, it works! Thanks again for all your help. Now all I have to do is draw a few more walking Lanas so it doesn't look so clunky, then implement your collision detection in one of the rooms, then make the NPC cat wander around, then draw a wardrobe and install it and code it, then make GUIs for various choices, then figure out how to use scale, then...all before next Wednesday!

Gazzzah, I think the suggestion was that you actually check the documentation, and see what methods are available. In terms of getting the finer details working, I think you need to narrow your questions down a bit, and perhaps post some code (whatever you have) to provide a basis for suggestions.

Thank you, will try!

Thanks so much! It worked perfectly : D

Well, all appears to be fine and dandy after cleaning up a bunch of code, I think I must've called the method twice? That was more difficult than it should've been :D.

Then 'p' is null.
